Latest Species Stories
Researchers have collaborated to determine whether or not DNA barcoding could be useful for monitoring marine mammal biodiversity. They determined that it could be a useful method in conjunction with a stranding network.
The ability to sequence the DNA of plants and animals has revolutionized many areas of biology, but the unstable character of DNA poses difficulties for sequencing specimens in museum collection over time.
DNA barcoding is used as an effective tool for both the identification of known species and the discovery of new ones.
Evolutionary scientists have long argued that species that live together must evolve in different ways in order to avoid direct competition with each other, but new research published Sunday in the journal Nature suggests otherwise.
More than a thousand new species –nearly one-quarter of which are new to science – have been discovered in Norway since a unique effort to find and name all of the country's species began in 2009.
While we tend to equate youth with strength and old age with weakness, new research appearing in the journal Nature reveals that frailty during the later years of life is not a fixed law of nature, and that some species actually become stronger and less likely to die as they age.
Researchers studying the evolutionary history of wild cats have made a shocking discovery – while scientists had long assumed that there was a single species of the Brazilian tigrina, they now know there are actually two of them.
The lowland tropics were once though filled with widespread species, while moderate and higher elevations were thought to contain species with more restricted distributions.
Life history traits are the basic ecological descriptors of a species. These include physical traits, such as body mass and physiological traits, such as reproductive rate.
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...
