Unlike their relatives, individuals of the poison frog Allobates femoralis are not poisonous but are captivating due to their different behavioral profiles: They successfully reproduce with different strategies depending on whether they are bold, aggressive or explorative. In addition, certain character traits are already present in this species at the tadpole stage.

Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.

A new analysis of 14,669 threatened species of plants and animals found in Europe reveals that about one fifth face the risk of extinction, and that agricultural land-use change poses a significant threat to these species.

Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.

Researchers say they have discovered high diversity of Darwin wasps in a tropical rainforest in Brazil, wasps which were previously thought to thrive more in cooler habitats.

The fascinating world of bacteria that live as symbionts or parasites in animal hosts often remains a mystery to researchers. A research team has made a breakthrough that provides insights into this mysterious micro-world.

Researchers have used fossil evidence to engineer a soft robotic replica of pleurocystitids, a marine organism that existed nearly 450 million years ago and is believed to be one of the first echinoderms capable of movement using a muscular stem.

New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.

They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.

Sharks and rays from threatened species are being caught off northern Cyprus, according to a new study by scientists who are working with local authorities and fishers to protect the animals.

Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.

By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation.

Researchers have developed a novel system to probe a rat's thoughts, finding that animals can control their brain activity to imagine remote locations.

A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.

A new analysis of the bones and muscles in ancient fish gives new clues about how the shoulder evolved in animals -- including us.

Local hunters in the Icefjord near Ilulissat have long known about a special ringed seal -- the Kangia seal -- which is significantly larger and has a markedly different fur color and pattern than typical Arctic ringed seals. Now scientific studies have shown that the Kangia ringed seal has been isolated from other ringed seals for a long period of time -- more than 100,000 years.

The world's largest dam removal and restoration project currently underway on the Klamath River in Oregon and California will aid salmon populations that have been devastated by disease and other factors. However, it will not fully alleviate challenges faced by the species, a team of researchers conclude.

New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
