Amazonian rivers don’t often drive the creation of new species, but do help maintain distinct populations, according to a study published in the journal Science Advances last month. Amazonian rivers…
In a counterintuitive surprise, a new study finds that fish species evolve more than twice as rapidly at the poles than in the tropics. The reason why isn’t currently known.
Evolution takes time and space. Enough time needs to pass for genetic differences to crop up in a population of animals and make them distinct from their forebears. And enough…
A new study drastically upends conventional wisdom about when plants colonized land, pushing back the date about 80 million years to around half a billion years ago. The new date…
Although they may lie thousands of miles apart and house different species, the world’s tropical forests may not be as different from each other as they seem to be. A…
Scientists have compiled a list of every known vascular plant found in North and South America, providing a new tool to understand how species are distributed throughout the two continents.…
A team of scientists from Seychelles, the United States and the United Kingdom has found a new caecilian, perhaps the smallest species of the legless amphibian on Earth. "As soon…
Camera trap footage has shown, for the first time, that a threatened bat species in Malaysia is an important pollinator of durian trees (Durio zibethinus). Past research in other parts…
Stable climates tend to have more bird species, according to new research. There’s a widespread notion that climate change encourages the proliferation of new animal species. But ecologist Roland Jansson…
The first DNA analysis of ancient straight-tusked elephant fossils may be changing what we know about elephant evolution. Scientists have presumed that a species of giant elephant called Palaeoloxodon antiquus,…
There are three orders in the class Amphibia, collectively comprising nearly 7,700 species. Of those three, the order Anura, which includes frogs and toads, represents 6,787 of the world’s known…
Roads have been described as “an enormous net over the land” and “the largest human artifact on earth.” There are more than four million miles of roads in the United…
Sometimes for a scientist, the disconnected pieces of years of research come together in a single, “really awesome” point in time. For ecologist Greg Asner, where it happened was about…
cientists have long known that invasive species possess “pesty traits” that benefit their spread. But what if similar, but latent, “pesty traits” could be triggered into action in endangered species…
There are only a handful of bird species known to use tools for foraging in the wild, and now the ‘Alalā, or Hawaiian crow, can be counted as one of…
Sex is getting complicated. Especially fish sex in New England. Scientists have recently discovered that fish in the northeastern U.S. are changing gender – and it’s not due to an…
Next year is the 100th Anniversary of the United States National Park Service, a branch of the Department of the Interior. The NPS largely owes its existence to one of…
Nature isn’t quite so natural anymore. Our interaction with the world around us has changed it drastically, and nowhere more so than in cities, vast artificial landscapes lacking in biodiversity.…
Rainforests are full of bats, and with over 1,300 known species around the world bats really do come in all shapes and sizes. Each species has its own range of…
Researchers find small-scale farming may lead to a loss of "650 million years of evolutionary history."
