Published Wild pig populations in U.S. can be managed



Recent conservation efforts have proven effective at controlling wild pig populations in the Southeastern United States, according to new research. Within 24 months of the start of control efforts in the study area located around the Savannah River Site in Aiken, South Carolina, researchers found a reduction of about 70% in relative abundance of pigs and a corresponding decline in environmental rooting damage of about 99%.
Published Tropical ecosystems more reliant on emerging aquatic insects, study finds, potentially putting them at greater risk



Researchers have found that tropical forest ecosystems are more reliant on aquatic insects than temperate forest ecosystems, making them more vulnerable to disruptions to the links between land and water. This is a significant finding, as tropical forests play a vital role in global biodiversity and climate regulation. The study's authors warn that any disruption to the land-water connections in these ecosystems could have serious consequences for their health and resilience.
Published Long-term lizard study challenges the rules of evolutionary biology



Researchers measured natural selection in four Anolis lizard species in the wild for five consecutive time periods over three years. This long-term study in a community of lizards reveals how evolution unfolds in the wild across multiple species.
Published Consistent metabolism may prove costly for insects in saltier water



Increased salinity usually spells trouble for freshwater insects like mayflies. A new study finds that the lack of metabolic responses to salinity may explain why some freshwater insects often struggle in higher salinity, while other freshwater invertebrates (like mollusks and crustaceans) thrive.
Published Natural GM crops: Grasses take evolutionary shortcut by borrowing genes from their neighbors



Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.
Published Bewick's swans choose wintering areas based on the weather



Bewick’s swans fly less far during their autumn migration when the weather is warm. Climate change has therefore led to a shift in their common wintering areas. Now, for the first time, bird researchers have been able to use long-term GPS data to pinpoint the specific choices that individual swans make.
Published Fear of humans pervades the South African savanna



Mammals living in South Africa's Greater Kruger National Park, home to one of the world's largest remaining lion populations, are far more afraid of hearing human voices than lion vocalizations or hunting sounds such as dogs barking or gunshots.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought



For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
Published Climate intervention technologies may create winners and losers in world food supply



A technology being studied to curb climate change – one that could be put in place in one or two decades if work on the technology began now – would affect food productivity in parts of planet Earth in dramatically different ways, benefiting some areas, and adversely affecting others, according to new projections.
Published Ruffed grouse population more resilient than expected, genetic study finds



Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
Published Invertebrate biodiversity is improving in England's rivers, long-term trends show



Rivers across England have seen a significant improvement in river invertebrate biodiversity since 1989, shows a new study.
Published Bird species changing faster than expected in protected areas



A recent study has found that bird communities inside and outside protected areas are beginning to resemble each other as a result of climate change. In both areas, southern species increase in abundance, while northern species decrease.
Published Birders and AI push bird conservation to the next level



Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
Published Honeybees are more selective in their choices for nutrition than previously thought



An international research group examined which plants honeybees favor when collecting nectar and pollen. The choices honeybees make have an impact on their health and also on humans, as honeybees pollinate important crop plants.
Published Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say



The increasingly urgent climate crisis has led to a boom in commercial tree plantations in an attempt to offset excess carbon emissions. However, authors argue that these carbon-offset plantations might come with costs for biodiversity and other ecosystem functions. Instead, the authors say we should prioritize conserving and restoring intact ecosystems.
Published Improved mangrove conservation could yield cash, carbon, coastal benefits



A shift in the way we think about the benefits mangroves provide to coastal regions could yield significant economic and biodiversity gains and protect millions from flooding, research has revealed.
Published Viruses dynamic and changing after dry soils are watered



Viruses in soil may not be as destructive to bacteria as once thought and could instead act like lawnmowers, culling older cells and giving space for new growth, according to research.
Published Study on mysterious Amazon porcupine can help its protection



A recent study sheds new light on the elusive Roosmalens' dwarf porcupine, a poorly understood neotropical species. After 22 years of relative obscurity, this research uncovers vital information about its distribution, phylogenetics, and potential conservation threats, not only revealing its endemic presence in the Madeira biogeographical province but also expanding its known range in the southern Amazon.
Published Genome study reveals 30 years of Darwin's finch evolution



An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin's finches. The study has revealed the genetic basis of adaptation in this iconic group.
Published Explosion in fish biodiversity due to genetic recycling



The rapid formation of 500 different species of fish in a single lake, each with specialized ecological roles, resulted from a small but genetically diverse hybrid population.
