Published Case study of rare, endangered tortoise highlights conservation priorities for present, future World Wildlife Days


Though wildlife trafficking has been effectively disrupted since the first World Wildlife Day -- established 50 years ago today via the 1973 Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora -- a newly published case study on one of the world's rarest tortoise species, the ploughshare tortoise, highlights how much room for improvement still exists.
Published Earlier take-off could lead to fewer bumblebees and less pollination


With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
Published U.S. birds' Eastern, Western behavior patterns are polar opposites


Scientists have established what could be considered a baseline map of annual avian functional and species diversity patterns in the U.S., finding that functional diversity patterns in the West, where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high.
Published Mulching time of forest meadows influences insect diversity


Researchers have examined how mulching at different times affects insect flower-visitors and larvae.
Published On a warming planet, these Arctic geese rapidly found (and shared) a new migratory route



As the planet warms, animals that breed in the Arctic are at particular risk. But a new study offers some encouraging news: in an apparent reaction to pressures along their former migratory route, a population of Arctic geese has rapidly adjusted, forming a new migration route and breeding location almost 1,000 kilometers from their original stomping grounds.
Published Deforestation in the tropics linked to a reduction in rainfall


Deforestation is resulting in reduced rainfall across large parts of the tropics, according to new research. People living in tropical forest communities have often complained that the climate gets hotter and drier once trees are cleared but until now, scientists have not been able to identify a clear link between the loss of tree cover and a decline in rainfall.
Published The counting of nine billion trees could help manage climate credits and nature restoration


Researchers have developed a method that has now mapped several billion trees and their carbon uptake in Africa's Sahel. In the future, the method could be used to monitor whether climate credit purchases have a positive effect on the number of trees and whether nature restoration is working.
Published Seabirds in the eye of the storm


Hurricanes are becoming more intense due to the climate crisis. Therefore, researchers have studied the wind speeds that different seabird species can withstand. The team was able to show that the individual species are well adapted to the average wind conditions in their breeding grounds, but use different strategies to avoid flying through the storm. Within their research, one behavior of the albatrosses particularly surprised the scientists.
Published Blue whale foraging and reproduction are related to environmental conditions, study shows



A new study of New Zealand blue whales' vocalizations indicates the whales are present year-round in the South Taranaki Bight and their behavior is influenced by environmental conditions in the region.
Published Better metric for prioritizing conservation of 'evolutionarily distinctive' species


Researchers have published an updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness.
Published Jurassic shark: Shark from the Jurassic period was already highly evolved


Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were already highly evolved in the Late Jurassic.
Published Flower power: The role of ants in forest regeneration


Ants play a key role in forest regeneration, according to a new article.
Published Australia's rarest bird of prey disappearing at alarming rate


Australia's rarest bird of prey -- the red goshawk -- is facing extinction, with Cape York Peninsula now the only place in Queensland known to support breeding populations.
Published Breathing is going to get tougher


Not all pollution comes from people. When global temperatures increase by 4 degrees Celsius, harmful plant emissions and dust will also increase by as much as 14 percent, according to new research.
Published Who are the first ancestors of present-day fish?


What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the 'bony-tongues' or the 'eels', was the oldest. A study has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of 'Eloposteoglossocephala'. These results shed new light on the evolutionary history of fish.
Published Exact magma locations may improve volcanic eruption forecasts


Cornell University researchers have unearthed precise, microscopic clues to where magma is stored, offering a way to better assess the risk of volcanic eruptions.
Published Looking back at the Tonga eruption


A 'back-projection' technique reveals new details of the volcanic eruption in Tonga that literally shook the world.
Published Immense diversity and interdependence in high temp deep-sea microorganism communities


A new study finds that microorganisms live in richly diverse and interdependent communities in high-temperature geothermal environments in the deep sea. By constructing genomes of 3,635 Bacteria and Archaea from 40 different rock communities, researchers discovered at least 500 new genera and have evidence for two new phyla. Samples from the deep-sea Brothers volcano were especially enriched with different kinds of microorganisms, many endemic to the volcano. The genomic data from this study also showed that many of these organisms depend on one another for survival. Some microorganisms cannot metabolize all of the nutrients they need to survive so they rely on nutrients created by other species in a process known as a 'metabolic handoff.'
Published Rare opportunity to study short-lived volcanic island reveals sulfur-metabolizing microbes


On the short-lived island of Hunga Tonga Hunga Ha'apai, researchers discovered a unique microbial community that metabolizes sulfur and atmospheric gases, similar to organisms found in deep sea vents or hot springs.
Published Predicting lava flow


A team is collecting data that will be used to create models that can help improve lava flow forecasting tools that are useful in determining how hazards impact populations. One such tool, known as MOLASSES, is a simulation engine that forecasts inundation areas of lava flow.
