An analysis of fossil teeth from mammals that lived in China following the most recent major mass extinction suggests size came before both shape and function as diets diversified.

New research from Monash University has provided the first comprehensive assessment of the Pilbara barking gecko (Underwoodisaurus seorsus) and revealed the species is facing a heightened risk of extinction under a rapidly warming climate.

Arguably one of the most curious ancient human relatives is Homo floresiensis, a 3-foot-tall species that lived on the Indonesian island of Flores and has been nicknamed "hobbit" for its diminutive stature. Even though they had small brains, scientists had thought they were surpr

When Dolly the sheep—the first cloned mammal—was born 30 years ago, she became one of the most famous animals in science history. Her arrival sparked predictions of a sci-fi future filled with cloned pets, cloned humans and even resurrected extinct animals like the wooly mammoth.

An interdisciplinary team from Florida State University's Department of Earth, Ocean, and Atmospheric Science has uncovered new evidence about processes that may have contributed to ancient mass-extinction events, some of the most dramatic ecosystem reorganizations in Earth's his

A squeaky frog that became an internet sensation is added to a global list of species at risk of extinction. O recorte ajuda a contextualizar a pauta dentro de Agro.

A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land animals died off during the Permian–Triassic extinction eve

Climate change threatens many plant and animal species not only when their habitats disappear as climatic conditions change, but also when those habitats shift. In a new study, a team of University of Potsdam researchers found that whether a species' habitat disappears or shifts

Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms

Przewalski's horses were once listed as extinct in the wild, with only a few remaining in captivity. O recorte ajuda a contextualizar a pauta dentro de Agro.

Estudo revela que gases liberados por rochas aquecidas após grandes eventos vulcânicos podem ter provocado mudanças climáticas extremas O post A lava é perigosa, mas há algo ainda pior nas erupções vulcânicas apareceu primeiro em Olhar Digital.

Cientistas desenvolveram ferramentas capazes de direcionar uma espécie à extinção deliberada. O bicheiro, parasita devastador do gado, é o candidato mais cotado para esse experimento sem precedentes.
