What makes two species different?

For most of the 20th century, scientists believed that the reproductive incompatibility between species evolved gradually as a by-product of adapting to different environments. New research has shown there are more factors at play...

Trees’ ‘enemies’ help tropical forests maintain their biodiversity

Scientists have long struggled to explain how tropical forests can maintain their staggering diversity of trees without having a handful of species take over -- or having many other species die out. The answer,...

450 fossilized millipedes found in 100-million-year-old amber

Since the success of the Jurassic Park film series, it is widely known that insects from the Age of the Dinosaurs can be found exceptionally well preserved in amber, which is in fact fossilised...

The oldest large-sized predatory dinosaur comes from the Italian Alps

Early Jurassic predatory dinosaurs are very rare, and mostly small in size. Saltriovenator zanellai, a new genus and species described in the peer-reviewed journal PeerJ -- the Journal of Life and Environmental Sciences by...

New insights on animal movement in fire-prone landscapes

A new Biological Reviews article considers how fire histories affect animals' movement and shape the distribution of species. The review article also considers how novel threats of altered fire regimes, landscape fragmentation, and invasive species...

Broading the biodiversity catalogue of spider populations in the Iberian Peninsula

The new study, covering the largest study area on this animal group in peninsular territory, is now published in the journal Biodiversity Data Journal. Other participants in the study are the experts from the...

Fossils suggest flowers originated 50 million years earlier than thought

Scientists have described a fossil plant species that suggests flowers bloomed in the Early Jurassic, more than 174 million years ago, according to new research in the open-access journal eLife. Before now, angiosperms (flowering plants)...

Explaining differences in rates of evolution

The rate at which evolution produces new species of plants and animals, or at which existing species die out, is a subject of much interest -- and not only to scientists. That's because the...

Could algae that are ‘poor-providers’ help corals come back after bleaching?

How much of the ability of a coral reef to withstand stressful conditions is influenced by the type of algae that the corals hosts? Corals are marine invertebrates from the phylum called cnidarians that build...

New butterfly named for pioneering 17th-century entomologist Maria Sibylla Merian

More than two centuries before initiatives to increase the number of women in STEM fields, 52-year-old Maria Sibylla Merian sailed across the Atlantic on a largely self-funded scientific expedition to document the animals and...
