Latest Species Stories
Biologists have long wondered why some animals ignore other species and others aggressively combat interlopers from another species.
In Part I, we talked about how tetrapods, a group of animals including whales, dolphins, seals and sea turtles, returned to the sea having once survived on land. Other creatures such as snakes and elephants may also have changed their habitat multiple times.
This week a ground-breaking new resource for scientists went live. More than twenty paleontologists, molecular biologists, and computer programmers from five different countries designed and contributed to a new open-source database that stores carefully reviewed fossil data and makes it accessible worldwide.
DNA research provides evidence that some species of Icelandic algae may have originated in northeastern Asia.
Flotsam from the 2011 Japanese tsunami is still washing up on the western shores of the United States and these drifting boats could be transporting invasive and dangerous species into North American waters.
Birds that are related, such as Darwin’s finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation.
A study in the current issue of Phycologia examines algae of the Corallinales order.
A cross-disciplinary team is calling for public discussion about a potential new way to solve longstanding global ecological problems by using an emerging technology called “gene drives.”
Old World monkeys have undergone a remarkable evolution in facial appearance as a way of avoiding interbreeding with closely related and geographically proximate species
A new study of how biodiversity arises, by evolutionary biologists at the University of Massachusetts Amherst, shows how a mutation in a single gene during development can lead to different consequences not only in how animals' skull and jaw are shaped, but how this leads to different feeding strategies to exploit different ecological niches.
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...
