The death of individual species is not the only concern for biologists worried about groups of animals, such as frogs or the "big cats," going extinct.
A new study from the National Institute for Mathematical and Biological Synthesis finds that a female's mating decisions are largely based on traits that reflect fitness or those that help males perform well under the local ecological conditions.
Efforts to restore sturgeon in the Great Lakes region have received a lot of attention in recent years, and many of the news stories note that the prehistoric-looking fish are "living fossils" virtually unchanged for millions of years.
These days, phylogeneticists – experts who painstakingly map the complex branches of the tree of life – suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings.
Charles Darwin predicted that a plot of land growing distantly related grasses would be more productive than a plot with a single species of grass in On the Origin of Species, first published in 1859. Over 150 years later, a study from the University of Toronto Scarborough (UTSC), reveals Darwin was right
If there is one thing you can say about families, it is that the larger the better. And by looking at genetic data of people from Ireland to the Balkans, researchers have found that Europeans are one big family, and have been for the past thousand years.
Tropical rainforests are known to harbor a high biodiversity of untold species, many of them unknown and unnamed by scientists as yet. Insects, especially beetles, make up a large proportion of this undiscovered life on Earth.
Studying the relationship between plants and the insects that feed on them is an arduous task, as it must be done through direct observation.
Alex Pyron’s expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles.
Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...
The Three-Spined Stickleback, Gasterosteus aculeatus, is a fish native to much of northern Europe, northern Asia and North America. It has been introduced into parts of southern and central Europe. Three subspecies that are currently recognized by the IUCN are Gasterosteus aculeatus aculeatus, which is found in most of the species range, and is the subspecies most strictly termed the Three-Spined Stickleback; its common name in England is the Tiddler, although "tittlebat" is also sometimes...
