Latest Species Stories
To understand how feeding interactions are structured, researchers from Finland and Canada chose to focus on one of the simplest food webs on Earth: the moths and butterflies of Northeast Greenland, as attacked by their specialist enemies, parasitic wasps and flies developing on their prey (called host), killing it in the process.
Amazonian biodiversity has been studied for hundreds of years. Despite this long history of exploration, new studies are resulting in the discovery of a large number of new species. The key of these discoveries lies in the use of advanced new tools for species detection.
Natural hybridization between two dolphin species likely helped to bring about the mysterious clymene dolphin, according to a study.
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.
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...
