The bluegill on your dinner plate might have been more social than the rest of its group, according to a new study from the University of Illinois, and its removal from the lake could mean major changes for the remaining population.
Fossils come in many shapes and sizes, ranging from isolated fragments of bones and teeth to complete skeletons.
Scientists have measured the nutritional value of herbivore dinosaurs' diet by growing their food in atmospheric conditions similar to those found roughly 150 million years ago.
Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species published in eNeuro. The work could have important implications for the translation of research in animal models to humans.
Genetic research at has shed new light on how isolated populations of the same species evolve toward reproductive incompatibility and thus become separate species.
In a new report in the journal Nature Communications, Erol Akçay, a biologist at the University of Pennsylvania, addresses the question of how an evolving social network influences the likelihood of cooperation in a theoretical social group. He finds that, although networks where connected individuals are closely related are more likely to cooperate, such groups can trigger a feedback loop that alters the structure of the network and leads to cooperation's collapse.
An international team, which included three University of Maryland researchers, sequenced and analyzed the genome of Chara braunii, a freshwater green alga closely related to land plants. By comparing Chara's genome to multiple land plant genomes, the team was able to identify many important genes that originated in a common ancestor shared by Chara and land plants.
University of Kansas scientists discovered that polyps have no qualms about treating a nonrelated individual like part of the family. This goes way beyond sharing meals or even a roof. Polyps of the marine hydrozoan Ectopleura larynx allow nonrelated individuals to fuse their bodies to the familial colony and share what is essentially skin and a stomach. The findings appeared yesterday in the journal Evolution Letters.
An interdisciplinary team of scientists at the Centre for Genomic Regulation in Barcelona, Spain, deepens understanding of tumor genome evolution and suggests negative selection acting on cancer-essential genes plays a more important role than previously anticipated. Their work, published in Genome Biology, also provides new insights for improving cancer immunotherapies in the future.
Biologists at the Ruhr-Universität Bochum characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. As published on the July 11, 2018, in PLOS ONE the scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior.
