In order to be effective, a Conservation Unit must have available a list of the species that live within it. They also should have detailed information about the distribution of species among the available habitats. It would be difficult to correctly plan the conservation actions and/or monitoring programs without some minimal knowledge about the species (who are the object of those measures). "This is why our study is so important to the park", said Dr. Miranda from Universidade Federal do Maranhão (CCAA/UFMA), leading author of the article, published in the open access journal ZooKeys.

In Lençóis Maranhenses National Park 42 species of reptiles were found. Approximately 80% of them live only in restinga habitats, which comprise about 20% of the area currently protected by the park. Restingas have been strongly disturbed by the clandestine openings of paths created to transport tourists to the dunes in the park, using off-road vehicles. This problem is more severe during the rainy season when paths become muddy quickly, and new ones are continuously opening. This could be extremely harmful to those habitats because their poor soil might severely limit natural recomposition.

"We recorded endangered species in Lençóis Maranhenses; particularly sea turtles located in the beach habitats. No one has any idea about the animal activity there! Are they spawning? It’s very likely, but we don’t have any data! It would be very important to study and monitor those species in the 70 km of beaches of the Lençóis Maranhenses National Park" adds Dr. Miranda.

Another turtle species, which deserves attention in Lençóis Maranhenses, is the Brazilian Slider Turtle, which has a limited geographic distribution in the coast of Maranhão, northeastern Brazil. This turtle is used as a source of food by the extremely poor inhabitants of Lençóis Maranhenses and surrounding areas.

"We believe that it would be helpful to promote awareness campaigns to help the conservation of that species, but it is equally important to provide alternatives to the people that live there. These inhabitants, for example, could be placed into the tourism business by providing training courses. They could work as tourist guides, waiters, or cooks. This would not only improve their economic capacity, but also free them of the need to use the Brazilian Slider Turtle as a food item. The efforts for conservation will only be successful with a joint effort of scientists, policymakers and society. We have to talk to one another and look for solutions together", concluded Dr. Miranda.

As a result of field work by associate professor James Davis Reimer and two graduate students from the University of the Ryukyus in Okinawa, Japan has found two new species of encrusting anemones, or colonial zoanthids, in unexpected locations. The species belong to the genus Neozoanthus, which was previously known only from a single species in the Indian Ocean. Surprisingly, the new species were found in the Pacific Ocean, in southern Japan and on the Great Barrier Reef, Australia. The study was published in the open access journal ZooKeys.

The only previous species of Neozoanthus was described in 1972 from Madagascar, and subsequently it was not seen for almost 40 years, until recent research had ascertained that new Pacific specimens likely belonged to Neozoanthus (Reimer et al. 2011, in the journal Marine Biology). The new study formally describes these new specimens as two species.

The members of this genus are small, with individual polyps no more than 6 mm in diameter, and have red, gray, blue or purple oral discs; all inhabit coral reef ecosystems in areas with strong currents and some siltation. Both new species and the species from Madagascar contain symbiotic, photosynthetic, single-celled algae that can provide them with energy from the sun.

"We were very surprised in 2008 to discover Neozoanthus in the Pacific, in Japan," said Reimer, "and initially thought that perhaps these were very rare." However, further research in southern Japan by graduate students Yuka Irei and Takuma Fujii, co-authors on the new paper, revealed that the Japanese species was locally common. A further surprise came during the Census of Marine Life’s Census of Coral Reef Ecosystems (CReefs) surveys on the Great Barrier Reef in 2009 and 2010, when similar encrusting anemones were found thousands of kilometers away from both Madagascar and Japan.

"These findings can be explained by the fact that there are very few zoanthid researchers in the world. These species are not particularly hard to find, but there was no one looking for them," Reimer added. "This research demonstrates how little we know about marine biodiversity, even in regions relatively well researched."

Field and laboratory work by a group of zoologists led by Omar Torres-Carvajal from Museo de Zoología QCAZ, Pontificia Universidad Católica del Ecuador, has resulted in the discovery of a new species of blunt-headed vine snake from the Chocoan forests in northwestern Ecuador. This region is part of the 274,597 km2 Tumbes-Chocó-Magdalena hotspot that lies west of the Andes. The study was published in the open access journal ZooKeys.

Blunt-headed vine snakes live in an area comprising Mexico and Argentina, and are different from all other New World snakes in having a very thin body, disproportionately slender neck, big eyes, and a blunt head. They live in trees and hunt frogs and lizards at night. The new species described by Torres-Carvajal and his collaborators was named Imantodes chocoensis and increases the number of species in this group of snakes to seven.

Snakes collected as far back as 1994 and deposited in several Ecuadorian and American natural history museums were also examined. The authors were soon surprised with an interesting discovery. Some individuals from the Ecuadorian Chocó lacked a big scale on their face that is present in all other blunt-headed vine snakes from the New World. Other features, as well as DNA evidence, indicate that these Chocoan snakes actually belong to a new species. DNA data also suggest that its closest relative is a species that inhabits the Amazon on the other side of the Andes.

‘One possible explanation for the disjunct distribution between the new species and its closest relative is that the uplift of the Andes fragmented an ancestral population into two, each of which evolved into a different species, one in the Chocó region and the other in the Amazon’ said Dr Torres-Carvajal.

Chromosome number is the most basic feature concerning the genome of a species, and it is known for about one third of higher plant species. In particular, for plants of Italy, Slovakia, and Poland, online chromosome number databases have been developed: ‘Chrobase.it – Chromosome numbers for the Italian flora’, ‘Karyological database of ferns and flowering plants of Slovakia‘ and ‘Chromosome number database – PLANTS‘, respectively. The three datasets account for about 35%, 60% and 40% of the whole floras, respectively.

"We used these datasets to compare chromosome number variation among plants of the three countries, with the aim to verify whether the patterns of chromosome number variation parallel the differences in latitudinal ranges" said Dr Peruzzi, leading author of the article, published in the open access journal Comparative Cytogenetics.

A concept that the occurrence of multiple genome copies (polyploidy) in plants tend to increase with latitude had already been formed in the second half of twentieth century, but pioneer works in this field had not significant statistical coverage, due to the absence of large, readily accessible datasets.

In the study, significant differences among the three countries were evidenced, confirming that mean chromosome number increases with increasing latitude. Mean chromosome number was used as an objective proxy of polyploidy.

In perspective, it would be interesting to verify whether the same chromosome number evolution dynamics occurs in the Austral hemisphere as well. Unfortunately, as far as we are aware, large chromosome number databases of these territories with significant latitudinal variations are not available, at the moment.

The leggiest animal in the world, the millipede lllacme plenipes, was re-discovered several years ago in California by Paul Marek. Now, Marek and his colleagues provide further details of the surprisingly complex anatomy of this diminutive creature and its extreme rarity, limited to a handful of spots just south of San Francisco. More details about the species and its biology can be read in an article that was recently published in the open access journal ZooKeys.

Millipedes have the most legs of any animal group. From their ancestors with just one pair of legs per body segment, millipedes evolved two pairs (four total) through segmental fusion. This coalescence of segments happened deep in the evolutionary history of millipedes, more than 400 million years ago. Four legs provide more thrust on a per segment basis, which benefits millipedes to help them burrow underground–e.g., to escape predators or access new resources. Those individuals with a coalescence of segments and hence a better burrowing ability, were able to persist in this early primordial ecosystem.

The most noticeable thing about millipedes are their number of legs, which lined up along their bodysides step in synchronous "metachronal waves". The acme of legginess in millipedes, and all animals for that matter, is the Californian species Illacme plenipes (literally meaning "in highest fulfillment of feet"). The females have up to an astounding 750 legs, outclassing the males who only have a maximum leg count of 562. The proliferation of legs may be an adaptation for its lifestyle spent burrowing underground or (based on the presence of features like legs with bifurcate claws and other traits known to be associated with rock-climbing in millipedes) enable it to cling tightly to the sandstone boulders found exclusively associated with the species in its habitat.

"This relict species is the only representative of its family in the Western Hemisphere. Its closest presumed relative, Nematozonium filum, lives in South Africa and this early relationship was established more than 200 million years ago when the continents coalesced in the landmass Pangaea", said the lead author Dr Paul Marek, from the University of Arizona.

Not only is this species the leggiest animal known on the planet, it also has surprising anatomical features: body hairs that produce silk, a jagged and scaly translucent exoskeleton, and comparatively massive (given its diminutive size) antennae that are used to feel its way through the dark because it lacks eyes. Its mouth, unlike other millipedes that chew with developed grinding mouthparts, is rudimentary and fused into structures that are probably used for piercing and sucking plant or fungal tissues.

This rare and ancient-looking creature’s home is California, on the outskirts of Silicon Valley. The species is exceedingly scarce and limited to just a single tiny area near San Juan Bautista, just east of the San Andreas Fault. Based on the known environmental conditions where it lives, the species’ probable distribution elsewhere in California was inferred. Yet still restricted to a small geographical range, the analysis indicated other areas of suitability limited to the terrestrial areas on the edge of Monterey Bay eastward to San Juan Bautista and throughout the Salinas Valley. What’s unique about this area, and seems to be correlated with the model’s area of highest suitability, is the thick layer of fog that accumulates in the area–like soup in a deep bowl. The fog and the species’ unique set of features in its habitat (oak forests, sandstone boulders, and fine sandy soil) make this area a special place and certainly deserving of attention as the home of this rare and superlative beast.

Arboreal tarantulas are known from a few tropical places in Asia, Africa, South and Central America and the Caribbean. These tarantulas generally have a lighter build, thinner bodies and longer legs, better suited for their habitat. They have increased surface area at the ends of their legs, allowing them to better climb different surfaces, while their light build makes them more agile.

Their core area is the Amazon, from where most of the species are known and normally very common, living in the jungle or even in house’s surroundings. Now, nine new species were described from Central and Eastern Brazil, including four of the smallest arboreal species ever recorded.

The study was performed by Dr Rogério Bertani, who is a tarantula specialist and a researcher at the Instituto Butantan in Sao Paulo, Brazil. His results have been published in the open access journal ZooKeys.

"Instead of the seven species formerly known in the region, we now have sixteen", said Dr Bertani. "In a resurrected genus with a mysterious single species known from 1841, we have now five species". "These are the smallest arboreal tarantulas in the world, and their analysis suggests the genus to be very old, so they can be considered relicts of a formerly more widely distributed taxon".

Other discoveries include new species of tarantulas living inside bromeliads. "Only a single species had been known to live exclusively inside these plants, and now we have another that specialized in bromeliads as well". A further species was found at the top of table mountains where trees are rare. "This species also inhabits bromeliads, one of the few places for an arboreal tarantula to live that offer water and a retreat against the intense sunlight" he says.

The discovery of all these new species outside the Amazon was unexpected and illustrates how little we know of the fauna surrounding us, even from hot spots of threatened biodiversity like the Brazilian Atlantic Rainforest and the Cerrado (a kind of savannah vegetation). These species are highly endemic and the regions where they live are suffering high pressure from human activities. Therefore, studies for their conservation are necessaries. Furthermore, all these new species are colorful, which could attract the interest for capturing them for the pet trade, constituting another threat.

A European-wide network for systematic GMO impact assessment proposed

In Europe there are many concerns about adverse environmental effects of genetically modified (GM) crops, and the opinions on the outcomes of environmental risk assessments (ERA) differ largely. GM crop safety testing and studies on the standardisation of impact assessments of releases are insufficiently developed. Therefore a framework was published in the open access journal BioRisk, which aims at improving the European regulatory/legal system.

Specific elements of the network are a) methodologies for both indicator and field site selection for GM crop ERA and PMEM, b) an EU-wide typology of agro-environments, c) a pan-European field testing network using GM crops, d) specific hypotheses on GM crop effects, and e) state-of-the art sampling, statistics and modelling approaches. Involving actors from various sectors the network will address public concerns and create confidence in the ENSyGMO results.

"Assessing GMOs on the basis of separate criteria may yield misleading results, with negative consequences for both nature and mankind. The impact of GMO should be analysed using integrated approaches and methods at various scales. We are convinced that the proposed assessment framework has the potential to set up a new standard in regulation of the usage of GMO" commented Dr Josef Settele from Helmholtz Center for Environmental Research – UFZ, Halle and Editor-in-Chief of BioRisk.

Increasing demand for bioenergy feedstock is generating land-use conflicts which are currently discussed in the food vs. fuel controversy and the debate about indirect land-use change. Concepts for solving those conflicts suggest a spatial segregation of food/feed and bioenergy producing areas. It is suggested to continue producing food/feed on established agricultural land while growing dedicated energy crops on so called "surplus" land.

Confusion in the applicability of those concepts is however caused by ambiguity in the definition and characterization of surplus land as well as by uncertainties in assessments of land availability, both on the national and the global scale, and of the potential yields of bioenergy crops when grown on surplus land.

‘We still have limited understanding of how much land is truly surplus and suitable for energy crop production’ said Dr Dauber, the lead author of the study, ‘because constraints arising from environmental and socio-economic implications of bioenergy development in those areas are often not accounted for in assessments of land availability’.

The authors suggest a thorough reassessment of land availability for bioenergy production by clarifying the terminology of surplus land and taking both constraints and options for efficient and sustainable bioenergy-land use into account. Policy recommendations for resolving conflicting land-use demands are provided.

In Dr Daubers opinion, ‘factoring in the constraints, combined with creativity in utilizing the options provided by the novel cropping systems, would lead to a more sustainable and efficient development of the bioenergy sector’.
