An Otago researcher has added another piece to the puzzle of the evolution of modern baleen whales with a world-first study examining the teeth and enamel of baleen whales' ancestors.
The world of the dinosaurs just got a bit more bizarre with a newly discovered species of freshwater shark whose tiny teeth resemble the alien ships from the popular 1980s video game Galaga.
Currently approximately 600 species might be inaccurately assessed as non-threatened on the Red List of Threatened Species. More than a hundred others that couldn't be assessed before, also appear to be threatened. A new ...
Plant phytolith and water content cause differing degrees of tooth enamel abrasion in vertebrates. This is the conclusion reached by an international research team headed by scientists from Johannes Gutenberg University Mainz ...
Fragmentation within intact forests has a higher impact on vertebrate biodiversity than equivalent losses in already degraded landscapes, but the relationship between forest 'intactness' and extinction risk has not been quantified.
Scientists look to fossils and evolutionary trees to help determine the rate of evolution – albeit with conflicting results. A new model by ETH researchers has helped to resolve these contradictions.
The complex network of interdependencies between plants and animals multiplies the species at risk of extinction due to environmental change, according to a JRC study.
