Scientists use forensic technology to genetically document infanticide in brown bears

Modern open-source software helped the researchers identify the male that killed a female and her two cubs

Scientists used a technology designed for the purposes of human forensics, to provide the first genetically documented case of infanticide in brown bears, following the murder of a female and her two cubs in Trentino, the Italian Alps, where a small re-introduced population has been genetically monitored for already 20 years.

The study, conducted and authored by Francesca Davoli, The Italian Institute for Environmental Protection and Research (ISPRA), Bologna, and her team, is published in the open access journal Nature Conservation.

To secure their own reproduction, males of some social mammalian species, such as lions and bears, exhibit infanticidal behaviour where they kill the offspring of their competitors, so that they can mate with the females which become fertile again soon after they lose their cubs. However, sometimes females are also killed while trying to protect their young, resulting in a survival threat to small populations and endangered species.

“In isolated populations with a small number of reproductive adults, sexually selected infanticide can negatively impact the long-term conservation of the species, especially in the case where the female is killed while protecting her cubs,” point out the researchers.

“Taking this into account, the genetic identification of the perpetrators could give concrete indications for the management of small populations, for example, placing radio-collars on infanticidal males to track them,” they add. “Nevertheless, genetic studies for identifying infanticidal males have received little attention.”

Thanks to a database containing the genotypes of all bears known to inhabit the study site and an open-source software used to analyse human forensic genetic profiles, the scientists were able to solve the case much like in a television crime series.

Upon finding the three corpses, the researchers were certain that the animals had not been killed by a human. In the beginning, the suspects were all male brown bears reported from the area in 2015.

Hoping to isolate the DNA of the perpetrator, the researchers collected three samples of hairs and swabbed the female’s wounds in search for saliva. Dealing with a relatively small population, the scientists expected that the animals would share a genotype to an extent, meaning they needed plenty of samples.

However, while the DNA retrieved from the saliva swabs did point to an adult male, at first glance it seemed that it belonged to the cubs’ father. Later, the scientists puzzled out that the attacker must have injured the cubs and the mother alternately, thus spreading blood containing the inherited genetic material from the father bear. Previous knowledge also excluded the father, since there are no known cases of male bears killing their offspring. In fact, they seem to distinguish their own younglings, even though they most likely recognise the mother.

To successfully determine the attacker, the scientists had to use the very small amount of genetic material from the saliva swabs they managed to collect and conduct a highly sophisticated analysis, in order to obtain four genetic profiles largely overlapping with each other. Then, they compared them against each of the males reported from the area that year. Eventually, they narrowed down the options to an individual listed as M7.

“The monitoring of litters is a fundamental tool for the management of bear populations: it has allowed the authors to genetically confirm the existence of cases of infanticide and in the future may facilitate the retrieval of information necessary to assess the impact of SSI on demographic trends,” conclude the researchers.

Researchers find post-fire logging harms Spotted owls

Wildlife ecologists studying the rare Spotted owl in the forests of California have discovered that large, intense wildfires are not responsible for the breeding territory extinction that has been reported recently.

Instead, the researchers found that post-fire logging operations, which are common on both private and national forest lands, were in fact causing the declines in the territory occupancy of this imperiled wildlife species. In areas, where no logging took place following large forest fires, the scientists failed to detect any significant effect in the spotted owls’ territory occupancy or extinction rate.

“This is good news for declining California spotted owls because this is something that we can control–we can make policy decisions to stop post-fire logging operations in spotted owl habitat,” says Dr. Chad Hanson, a research ecologist with the John Muir Project of the Earth Island Institute and the study’s lead author. His team’s article is published in the open access scientific journal Nature Conservation.

The study sheds light on recent large fires, such as the 99,000-acre King fire from 2014 which affected the Eldorado National Forest in the Sierra Nevada Mountains. As a result, spotted owl occupancy declined in the northern portion of the King fire area. However, the present study finds post-fire logging is to blame.

Post-fire logging removes important spotted owl foraging areas in “snag forest habitats” created by patches of intense fire, explain the scientists. These habitats are rich in small mammal species preyed on by the owls, whereas post-fire logging destroys these habitats, causing higher territory extinction rates.

The study also reports that many of the spotted owl territories in the King fire, which were previously described as lost due to the fire, had in fact already been unoccupied for years before it occurred. Other factors acting before the fire turn out to have been responsible for the occupancy changes at these sites.

The scientists’ findings also help to explain why previous research has found very high spotted owl occupancy in the 257,000-acre Rim fire in the Sierra Nevada prior to post-fire logging, which was then followed by a decline in owl territory occupancy after such logging occurred.

“These results were not surprising considering that spotted owls evolved with forest fires, but logging is a new disturbance to which they are not adapted,” says co-author Monica Bond, a wildlife ecologist with the Wild Nature Institute.

Wildlife researcher and co-author Derek Lee, also affiliated with the Wild Nature Institute, adds, “It is time to stop thinking logging will help the forest; we need to take a much more hands-off approach to forest management, so natural processes can be re-established.”

The study’s results coincide with the strong consensus among hundreds of U.S. scientists opposing post-fire logging operations due to a wide range of ecological harms. Pro-logging members of the U.S. Congress have recently pointed to large forest fires as a justification for proposed logging bills that would override most environmental laws and dramatically increase logging, including post-fire logging, on U.S. National Forests and other public lands.

The results of this study indicate that such legislative proposals would contradict scientific evidence, and harm spotted owls populations. Other studies have also indicated that increased logging would substantially reduce forest carbon storage, and increase greenhouse gas emissions, exacerbating climate change.

Special issue: Natura 2000 appropriate assessment and derogation procedure

The focus is on the case-law of the European Court of Justice and the German Federal Administrative Court

With over 27,500 sites, Natura 2000 is the greatest nature conservation network in the world. It covers more than 18 percent of the land area in the European Union and around 395,000 km2 of its marine territory.

Projects and plans within those sites or in their vicinity require an appropriate assessment to ensure that they will not have a significant impact on the integrity of a Natura 2000 site, according to Article 6(3) of the Habitats Directive 92/43/EEC. The Natura 2000 appropriate assessment is the central statutory instrument for the protection of the network, in addition to the general prohibition of deterioration.

An assessment must take place prior to the authorisation and implementation of a project or a plan. As a result of the European Court of Justice (ECJ) having maximised the effectiveness of the assessment by a stringent legal interpretation, a project or a plan must be rejected by the competent authorities if there is any remaining reasonable scientific doubt that it might adversely affect the integrity of the site.

Nevertheless, in accordance with the European principle of proportionality, the Habitats Directive does not intend to ban all human activity in Natura 2000 sites. This is the reason why, on the one hand, only significant adverse impacts on the integrity of a Natura 2000 site are relevant and, on the other, according to Article 6(4) Habitats Directive, a derogating authorisation is possible in favour of public interests.

However, numerous questions, which are relevant in practice, have so far only been considered by national courts. A special issue recently published with the open access journal Nature Conservation features a comprehensive review of the relevant case-law of the German Federal Administrative Court (BVerwG), which has thoroughly dealt with the Natura 2000 regime in a long series of judgements.

The author, Dr. Stefan Möckel of the Helmholtz-Centre for Environmental Research GmbH, Germany, is a long standing specialist in European and German nature conservation law. Within the four articles comprising the issue, he analyses the scope, procedural steps and requirements of the appropriate assessment and the derogation procedure. He also comments on the interpretations and practical solutions found by the ECJ and the BVerwG.

The first article explains the main steps and demands of the appropriate assessment. Questions on the scope of the terms “project” and “plan”, as well as determining significant impacts are discussed in greater detail in the second and third article. The fourth paper explores the requirements needed for a derogation to be approved.

Light at the end of the tunnel: Restored forest now shelters dozens of endangered species

During the last twenty years, scientists worked hard to protect and restore the scattered patches of a dilapidated forest and its surroundings of agricultural and fallow vegetation in southern Benin.

With the help of their locally recruited assistants, Peter Neuenschwander, International Institute of Tropical Agriculture, Benin, and Aristide Adomou, University of Abomey-Calavi, Benin, successfully thinned out the alien timber growing there and introduced 253 species, whose seeds and plantlets they had managed to collect from the last remnants of the original forest. Their research article is published in the open access journal Nature Conservation.

Today, the rehabilitated forest in Drabo harbours about 600 species of plants and constitutes a sanctuary for many animals, including the critically endangered and endemic red-bellied monkey.

Over the course of the last two decades, pantropical weedy species declined, while West-African forest species increased in numbers. Of the former, fifty-two species, mostly trees, shrubs and lianas, are listed as threatened – more than those in any other existing forest in Benin. Furthermore, some of the critically endangered species amongst them can be found exclusively in the last small, often sacred forests in Benin, which while covering merely 0.02% of the national territory, harbour 64% of all critically endangered plant species.

“The biodiversity richness of the rehabilitated forests of Drabo now rivals that of natural rainforest remnants of the region,” note the authors.

The newly restored forest in Drabo is relatively easy to access due to its proximity to large towns. It is intended to become an educational and research centre maintained by the International Institute of Tropical Agriculture. In fact, it already serves as an exemplary forest in the region.

With their initiative, the scientists and their followers demonstrate that by involving local communities and taking their customs into consideration, the safety of exposed precious ecosystems, even if located in a densely populated area, can be effectively assured.

Lion conservation requires effective international cooperation

Lions belong to the world’s most charismatic megafauna. However, lion numbers and range have declined alarmingly over the last two decades.

“To turn the tide, international cooperation is crucial,” says a team of lawyers, conservation biologists and social scientists.

In their recently published review article in the journal Nature Conservation, they assess the current and potential future role of international treaties regarding lion conservation.

To conduct this study, international wildlife lawyers Arie Trouwborst and Melissa Lewis from Tilburg Law School in the Netherlands teamed up with lion experts David Macdonald, Amy Dickman and other scientists from the University of Oxford‘s Wildlife Conservation Research Unit (WildCRU) – the research group that made Cecil the lion famous.

Their analysis clearly shows the importance of various global and regional treaties for lion conservation.

For instance, dozens of important lion areas have received international protection under treaties like the World Heritage Convention and the Ramsar Wetlands Convention, whereas trade in lion bones and hunting trophies is regulated through the Convention on International Trade in Endangered Species (CITES).

“There is still much room for improvement in the way the international commitments of lion range states are applied on the ground,” the review notes.

However, the authors conclude that it is worthwhile to invest in such improvements, and stress the importance of strategies involving the local people who live alongside lions. The review offers many concrete recommendations for optimising the contributions of the various treaties to lion conservation.

A particularly important recommendation is to formally list lions under the Convention on the Conservation of Migratory Species (CMS). A proposal to list lions is on the agenda of the next intergovernmental summit of the parties to the CMS in October this year.

As lead author Arie Trouwborst explains:

“Listing the lion would raise the profile of this iconic species, and would moreover enable the CMS to provide a framework for coordinating and assisting conservation efforts in the 25 countries where lions still occur in the wild.”

According to David Macdonald, Director of WildCRU:

“Biology is necessary, but not sufficient, to inform and deliver wildlife conservation. Our approach at the WildCRU in Oxford is holistic – this new partnership with international lawyers is a symbol of our determination to embrace knowledge from every discipline, leaving no stone unturned in our quest to conserve these iconic animals.”

Nature Conservation Special: Guidelines for the monitoring of beetles protected in Europe

In a follow-up to a recent special issue, 8 research articles outline a set of verified guidelines for the monitoring of 5 saproxylic beetle species listed in the Habitats Directive

In a set of eight research publications, scientists tested various methods for the monitoring of five European saproxylic (i.e. dependent on dead wood) beetle species protected by the Habitats Directive. The aim of their work was to test and propose a standard method for each species. A key role in this conservation initiative was played by citizen scientists who made it possible for sufficient data to be collected within a significantly shorter time frame.

The special issue “Guidelines for the monitoring of the saproxylic beetles protected in Europe” is the second in succession published in the open access journal Nature Conservation. Both are produced within the framework of the European Union’s LIFE Programme Project “Monitoring of insects with public participation” (LIFE11 NAT/IT/000252 MIPP) and were presented at the European Workshop held in Mantova in May 2017. Colonel Franco Mason, project manager of the MIPP project, notes that the workshop was aimed primarily at monitoring of saproxylic beetles.

While the first article collection focused on reporting recent findings derived from monitoring surveys across the European Union, the papers in the latest issue are devoted to testing various methods for the monitoring of five selected species of protected beetles, in order to determine the most efficient methods and, subsequently, to propose them as standard methods.

Curiously, the public participation in the project was not limited to ecology and entomology semi-experts and aficionados. The team specifically targeted children when recruiting volunteers. One of the dissemination activities of the MIPP project was the “MIPP-iacciono gli insetti” (translated to “I like insects” from Italian), where 3000 students from primary to high school undertook 60 activities per year in order to learn how to locate and identify the target insects.

“Participation by children in environmental education programmes seems to have a great impact on their attitude and behaviour,” notes Giuseppe Carpaneto, Roma Tre University and his co-authors in their introductory article.

“Some studies have shown that children who participate in such programmes are more concerned about nature, want to learn more about environmental issues and are more prone to follow pro-environmental behaviour (e.g. waste recycling) than children who did not participate”.

In another article, included in the special issue, Fabio Mosconi of the Italian Agricultural Research Council and Sapienza University of Rome and his co-authors tested whether a specially trained Golden Retriever could locate the threatened hermit beetle faster and more efficiently than scientists using the standard “wood mould sampling” method.

Do squirrels teach bears to cross the railroad? Grizzlies dig squirrel middens for grains

Grains have been reported to regularly trickle from hopper cars travelling via the railway located within the Canadian Banff and Yoho National Parks, attracting the local red squirrels.

As a result, the rodents have grown used to foraging on the spilled seeds, which they collect in underground storage areas where they can be discovered and dug up by grizzly bears. Grain-conditioned bears may frequent the railway more often than usual, resulting in increased mortality by trains strikes.

Furthermore, the dispersal, following caching and digestion of such seeds by both squirrels and bears, could lead to the spread and establishment of those agricultural plants in the area.

The case is investigated and discussed by members of the University of Alberta‘s research team of Julia Elizabeth Put, Laurens Put and Dr. Colleen Cassady St. Clair. Their study is published in the open access journal Nature Conservation.

It all began when members of the team found a grain-filled midden that was visited by a bear near where the same bear had bluff-charged Parks Canada employees. At the time, the researchers were investigating possible explanations for causes of grizzly bear mortality on the adjacent railway. Thus, an unexpected opportunity to document interactions between species and how those can lead to human-wildlife conflicts presented itself to the scientists.

The three basic questions brought up by Julia and her team were whether spilled grain could increase the number of squirrels near the rail; if other middens contained grain; and if other bears accessed grain in middens. Eventually, their data provided a resounding ‘yes’ to all of them.

In some mountain parks in North America, including Banff, grizzly bears are known to excavate squirrel middens to access whitebark pine seeds. The tree, however, is only found at high elevations far from the valley bottom where the railway is located. Nevertheless, this behaviour may easily translate to targeting other food items in middens, such as grain, speculate the researchers.

Once a bear consumes grain from a squirrel midden, it could initiate or reinforce a tendency to seek grain on the rail, where it is generally less concentrated. Such conditioning of food rewards could lead to grizzly bears spending more time in the area around or on the rails, where they would be at risk of being struck by trains.

“The only feasible mitigation for these effects is to reduce spillage from hopper cars via careful attention to loading and gate maintenance,” conclude the authors.

Claims that declines of pollinator species richness are slowing down in Europe revisited

Having conducted a thorough interpretation of the results of a recent study that inferred decrease in the biodiversity loss among pollinators across Europe, Dr Tom J. M. Van Dooren reveals that this conclusion cannot in fact be drawn. It is only supported for the bee fauna in the Netherlands. His study is published in the open access journal Nature Conservation.

Changes in pollinator abundances and diversity are of major concern. Pollinator diversity is quantified by their species richness: the number of species from a specific taxonomic group of pollinating animals present at a given time in a given area. A recent study, adopted in the recent UN IPBES Pollination Report draft summary, inferred that pollinator species richnesses are decreasing more slowly in recent decades in several taxonomic groups and European countries.

However, Dr Tom J. M. Van Dooren, affiliated with both Naturalis Biodiversity Center, the Netherlands, and the Institute of Ecology and Environmental Sciences of Paris, France, has now published his own study to show in detail the inaccuracies that the earlier conclusion has been based on.

Among other points, the scientist notes that the earlier study contained no explicit statistical comparisons between species richness changes in different periods. The earlier study also treated richness changes at country level and small spatial resolution as equivalent, while they probably represent different processes.

“Plants in Great Britain at the smallest spatial scales suggest a reduced rate of changes, but the results for larger spatial scales are not significant,” he illustrates. “The same holds for butterflies in the Netherlands.”

Dr Tom J. M. Van Dooren only finds support in the results of the earlier publication for a decelerating decline in bumblebees and other wild bees in the Netherlands. “This is in fact one taxon, the bees Anthophila, in a single country, the Netherlands”, he notes.

“The lack of robustness points again to the possibility that results found in the data can be due to changes in the shapes of species accumulation curves,” Dr Tom J. M. Van Dooren summarises. “Therefore the status of the statement on decelerating declines in the Pollination Report should be adjusted accordingly.”

Online sales of threatened cacti point to the Internet as an open door for illegal trade

International trade of wildlife on the Internet is highly unregulated and has become a threat for species survival. Threatened cacti are available on websites and shipped across countries without any legal documents to certify their trade is not a menace to population viability in the wild. Is this ignorance or unwillingness to comply with regulations? Study published in the open access journal Nature Conservation reports on the activity and discusses assessment methods and solutions.

In present days, trade of species is possible without any real human interaction, and distance is no longer an obstacle. Although conventional trade routes are maintained through shipping of goods, the widespread use and the unregulated nature of the Internet make e-commerce a great concern to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

This convention regulates international trade through issuing and control of permits, which aim to guarantee that the trade of individuals is not a threat to the survival of a species in the wild. Due to the magnitude of the international trade, the entire cacti family is under CITES.

In their study, scientists Vania Olmos-Lau and Dr María C. Mandujano, both affiliated with the Universidad Nacional Autónoma de México (UNAM), México, present a quick and easy method to assess the online availability of a highly collectible Mexican threatened cactus, commonly known as disc cactus. The method can be readily used to assess other species.

Because of its threatened status, no commercial trade of wild specimens is allowed and a collection permit is needed for harvest of seeds and individuals. Plants and seeds were found available in major online markets like eBay and Amazon, and were also offered via online stores based in the USA, France, Germany, Australia, the Czech Republic, the UK, and others. Researchers point out that the Asian market was underestimated due to language constraints.

Only a minority of these online stores openly stated that they would provide CITES documentation, or that plants were obtained from nurseries that grew cacti themselves. Results also indicate that the country home to this species, Mexico, plays no important role in the legal international trade of the species.

“This method is easily transferable to estimate the illegal market for any species and offers an understanding of the real magnitude and main targets of this new form of threat,” note the authors. “Compliance or other regulation mechanisms are needed in order to promote species conservation.”

For major online stores like eBay, Mercado Libre and Amazon, the researchers propose a policy based on filtering the publications which contain the name of CITES species.

For example, there could be downloadable forms for the sellers to sign and prove that they assume responsibility for the legal origin of the product. Also, a pop up window could let buyers know what a CITES species is and what its acquisition involves. After all, most times the lack of compliance with regulations for wildlife trade is a matter of ignorance rather than disobedience.

“We need to open our eyes to the demand for wildlife and how it can be satisfied through fair trade schemes that benefit local landowners,” point out the researchers.

Thousands of illegally traded wild animals at risk due to gaps in data

The fate of over 64,000 live wild animals officially reported to have been confiscated by CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) enforcement agencies between 2010 and 2014 remains untraceable, according to a new report released by the University of Oxford Wildlife Conservation Research Unit (WildCRU) and World Animal Protection.

In their publication in the open access journal Nature Conservation, the researchers document merely one in three partnering to CITES countries providing any data on seizures, and also highlight the importance of having this changed.

Although the reported number of confiscated animals is staggering, the researchers warn that these are likely to be only a fraction of the actual seizures. The study found two out of three countries did not report any live wildlife seizures, despite poaching of endangered species and supplying the illicit global wildlife trade being estimated to be worth between $8-10 billion per year.

The figures have prompted calls for better reporting of seizures and what happens to confiscated live wild animals.

The ultimate fate of seized live wild animals is unknown, the researchers found. Once animals have been confiscated, national authorities must decide whether to: keep them in captivity, return them to the wild or euthanize them. CITES provides guidelines to aid this decision-making based on the conservation status and welfare needs of the animals.

However, information about the fate of these wild animals is not a formal CITES requirement and as a result, there are no official numbers on just how many were euthanized, placed in captivity or returned to the wild.

Researchers are concerned this lack of data is placing the well-being and survival of seized wildlife at risk – many wild animals could be re-entering the wildlife trafficking industry as they simply can’t be accounted for.

University of Oxford‘s Professor David Macdonald, senior researcher for the study, said:

“We fear this staggering number is just the tip of the iceberg. Only a relatively small proportion of wild animals involved with illegal trade are thought to be intercepted by enforcement agencies – confiscation records were completely missing for 70% of countries Party to CITES. Given the rapidly growing global trends in illegal wildlife trade activity, it is highly unlikely that no live wildlife seizures were made on their borders.

“The records that were provided show that around 20% of all live wild animals reported as seized are currently considered to be threatened by extinction. We strongly recommend that the CITES trade database should include information on the fate of all live wild animal seizures, so we know what happens to these animals, and we can reduce the risk of them re-entering the illegal wildlife trade.”

World Animal Protection’s Dr Neil D’Cruze, lead researcher for the study, said:

“The illegal wildlife trade is a big, complex and dirty business. National authorities play a key role, facing some tough choices when they seize animals – whether they release them in the wild, place them in care in captivity or euthanize them.

“Improved data recording is critical to knowing what happens to each animal, and can help in looking at the challenges and issues enforcement agencies face in managing animals after seizure. Without this transparency, there’s a real possibility that endangered species may be put back into the hands of the same criminals whom they were taken from. We need to be able to account for these wild animals.

“If we’re really serious about protecting wildlife, action needs to be taken at all levels. It’s unfathomable that 70% of countries recorded no seizures when we know a global, multi-billion wildlife trafficking industry is flourishing.”

###

The findings and recommendations of this research were presented at the 17th meeting of the Conference of the Parties (CoP) in Johannesburg, South Africa on 27 September 2016 during a side event focused on the confiscation of live wild animals organised by the Species Survival Network (SSN).
