Coastal wading birds shape their lives around the tides, and new research in The Auk: Ornithological Advances shows that different species respond differently to shifting patterns of high and low water according to their size and daily schedules, even following prey cycles tied to the phases of the moon.
Although sperm whales have not been driven to the brink of extinction as have some other whales, a new study has found a remarkable lack of diversity in the maternally inherited mitochondrial DNA within the species.
Discovering that the association between trees and two classes of underground mycorhizzal fungi can be detected from space is a huge leap forward in our ability to understand how forests change on a large scale because the fungi are indicators of forest nutrient uptake.
Researchers know that several proteins are involved in oyster shell formation, but how expression of these proteins is controlled is not well understood. Now investigators report that they have identified a protein called Pf-POU3F4 that promotes expression of two of these proteins, called Aspein and Prismalin-14.
Scientists raise are raising awareness that long-term use of herbal remedies is no guarantee of their safety. Herbal remedies are an overlooked global hazard.
New research challenges the traditional view that baleen whales (Mysticetes) migrate between high-latitude feeding areas and low-latitude breeding areas.
University of Leicester students examine plausibility of all the humans on Earth shedding enough tears to form a river -- and fill an Olympic size swimming pool.
A class of 150 7th graders from the USA has helped select a name for a newly discovered plant from Australia. Bucknell University biology professor Chris Martine and life science teacher Bradley Catherman challenged the students to come up with ideas for what to call the new species last spring. Nearly a year later, Martine and his co-authors, including two undergraduate students, have published the new species in the open access journal PhytoKeys.
How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists at Uppsala University and their colleagues report that whole genome sequencing of Atlantic and Baltic herring revealed hundreds of loci underlying adaptation to the brackish Baltic Sea or timing of reproduction. The study is published today in eLife.
A study has found that a cellular syringe-like device used to invade intestinal cells also acts as a traffic cop -- directing bacteria where to go and thereby enabling them to efficiently carry out infection. This mechanism is critical to a pathogen's success.
