Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.

Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.

A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.

A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species including the native common octopus and the invasive red-eared slider, which are both relevant to Japan.

Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.

An international group of researchers has created a mixed magnon state in an organic hybrid perovskite material by utilizing the Dzyaloshinskii--Moriya-Interaction (DMI). The resulting material has potential for processing and storing quantum computing information.

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.

The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.

Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.

In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.

While pollinator populations of many species have plummeted worldwide, one bee species is blowing up the map with its rapid population expansion. The key to this insect's success? Its passion for pumpkins, zucchinis, and other squashes, and the massive increase in cultivation of these crops across North America over the last 1,000 years. A new study found that the squash bee (Eucera pruinosa) has evolved in response to intensifying agriculture -- namely squashes in the genus Curcurbita. The research has demonstrated the role of agriculture as an evolutionary force acting on a wild insect pollinator and may have implications for food security.

Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.

The McCloud River redband trout, or O. mykiss calisulat, is newly identified as its own distinct subspecies of rainbow trout in a new study. It was named in consultation with the Winnemem Wintu tribe.

Moths are more efficient pollinators at night than day-flying pollinators such as bees, finds new research.

Physicists predict that layered electronic 2D semiconductors can host a curious quantum phase of matter called the supersolid. This counterintuitive quantum material simultaneously forms a rigid crystal, and yet at the same time allows particles to flow without friction, with all the particles belong to the same single quantum state.

A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.

Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.

New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.

Researchers collected the bodies of birds that crashed into buildings while migrating, and used these specimens to learn about the relationship between birds and the microbes living in their guts -- which appears to be wildly different from mammals and their microbiomes.
