Bird diets provide a real treasure for research into the distribution and conservation of their prey, conclude scientists after studying the Eurasian Eagle Owl in southeastern Bulgaria. In their paper, published in the open-access, peer-reviewed journal Travaux du Muséum National d’Histoire Naturelle “Grigore Antipa”, they report the frequent presence of the threatened Big-Bellied Glandular Bush-Cricket, and conclude that studies on the Eurasian Eagle Owl could be used to identify biodiversity-rich areas in need of protection.
Recent study conducted at a UK fishery farm provides new evidence that DNA from water samples can accurately determine fish abundance and biomass Organisms excrete DNA in their surroundings through metabolic waste, sloughed skin cells or gametes, and this genetic material is referred to as environmental DNA (eDNA). As eDNA can be collected directly from […]
Guest blog post by Marcos Caraballo The birdcatcher trees – genus Pisonia – are infamous for trapping birds with their super-sticky seed pods that would frequently entangle the body of the ‘victim’. Left flightless, the poor feathered creatures eventually die either from starvation or fatigue, or predators. Similarly notorious are the birdcatcher trees for botanists, […]
For the first time, a complete time-calibrated phylogeny for a large group of invertebrates is published for an entire continent. A German-Swedish team of scientists provide a diagrammatic hypothesis of the relationships and evolutionary history for all 496 European species of butterflies currently in existence. Their study provides an important tool for evolutionary and ecological research, meant for the use of insect and ecosystem conservation.
In recent years, the concept of Ecosystem Services (ES): the benefits people obtain from ecosystems, such as pollination provided by bees for crop growing, timber provided by forests or recreation enabled by appealing landscapes, has been greatly popularised, especially in the context of impeding ecological crises and constantly degrading natural environments. Hence, there has been […]
New open-access book presents a comprehensive report on the remarkable ecosystems of the Koytendag nature reserve Situated in the extreme south-east of Turkmenistan: on the border with Uzbekistan and close to the border with Afghanistan, Koytendag presents one of the most distinct landscapes in Central Asia. Reaching elevations of up to 3,137 m, this is […]
While exploring the way alien species invade cities around the world, South African PhD student Ashlyn L. Padayachee (University of KwaZulu-Natal, UKZN) and her supervisors, Serban Proches (UKZN) and John Wilson (SANBI and Stellenbosch University) remember suddenly being stricken. What they realised was that while cities were gradually starting to prepare for climate change, their responses to […]
Earlier this year, a research article triggered a media frenzy by predicting that as a result of an ongoing rapid decline, nearly half of the world’s insects will be no more pretty soon Amidst worldwide publicity and talks about ‘Insectageddon’: the extinction of 40% of the world’s insects, as estimated in a recent scientific review, a critical […]
Commonly known to predate on insects, praying mantises have occasionally been observed to feed on vertebrates, including small birds, lizards, frogs, newts, mice, snakes and turtles. Mostly, such records have either not been scientifically validated or have occurred under induced and human-manipulated circumstances. Nevertheless, no scientific data of mantises preying on fish existed until the […]
Originally collected 28 years ago in Ecuador, new species Poa laegaardiana has been just described, only to find out its prospects for surviving in its type location seem bleak nowadays. The study was published in the open access journal PhytoKeys. When roaming in the Cordillera de los Andes of Ecuador, near the village of Facundo Vela, little did Smithsonian scientist and author, […]
