Bats may have lived in caves and used soundwaves to navigate much earlier than first thought.

Many people have experienced a muddy off-flavor in farmed fish. While the aquaculture industry has known about the problem for 20 years, it continues to impact the consumption of otherwise healthy and potentially sustainable fish. Now, researchers have been able to pinpoint exactly when the off-flavors emerge. And this can make it easier to deal with the compounds that turn people away from farmed fish.

Researchers have harnessed the power of baker's yeast to create a cost-effective and highly efficient approach for unraveling how plants synthesize medicinal compounds, and used the new method to identify key enzymes in a kratom tree.

Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.

The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.

Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.

Researchers say mapping the genetic code of the brushtail possum will benefit those working to both conserve and control the animal.

Animal sounds are a very good indicator of biodiversity in tropical reforestation areas. Researchers demonstrate this by using sound recordings and AI models.

In the world of threatened and endangered species conservation, the genomic revolution has raised some complicated questions: How can scientists justify assessing species genetic diversity without consulting entire genomes now that they can be sequenced? But then again, how can scientists justify the time and expense of genome sequencing when age-old measures of neutral genetic diversity are much cheaper and easier to obtain? A new study suggests making a transition from 'old school' genetics to 'new school' genomics for species conservation purposes probably isn't necessary in all cases.

Populations of charismatic animals have recovered since hunting ban but now struggle to find enough food.

'Flagship' individual animals like Cecil the lion or Freya the walrus can boost conservation, new research suggests.

Tens of thousands of endangered sharks and rays are caught by small-scale fisheries off the Republic of the Congo each year, new research shows.

Both elegant and fierce, killer whales are some of the oceans' top predators, but even they can be exposed to environmental pollution. Now, in the largest study to date on North Atlantic killer whales, researchers report the levels of legacy and emerging pollutants in 162 individuals' blubber. The animals' diet, rather than location, greatly impacted contaminant levels and potential health risks -- information that's helpful to conservation efforts.

Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan now supports the idea.

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%.

Due to the changing climate, the underwater world is getting ever noisier.

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.

Grass may transfer genes from their neighbors in the same way genetically modified crops are made, a new study has revealed.

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.
