Methods used to design F1 cars and spacecraft have played a crucial role in new research into the tags used to track animal movements. Ecologists teamed up with aerospace colleagues at Swansea University to find the best way to reduce the drag of biologging tags -- the recording devices used to track animal movements and behaviour.
Horseshoe crabs that have undergone biomedical bleeding tend to reside in deeper water and approach mating beaches less often, according to a new study published in The Biological Bulletin. In 'Effects of the Biomedical Bleeding Process on the Behavior of the American Horseshoe Crab, Limulus polyphemus in Its Natural Habitat,' Meghan Owings and her colleagues report the results of an investigation of the behavioral and physiological effects that the bleeding process has on horseshoe crabs that are released back into their natural environment.
A team of University of Copenhagen researchers has compiled the first and only evidence that narwhals and beluga whales can breed successfully. DNA and stable isotope analysis of an anomalous skull from the Natural History Museum of Denmark has allowed researchers to confirm the existence of a narwhal-beluga hybrid.
A new paper examines the rarely explored coral reefs in deep water, where less than 1% of light from the surface makes it through. The research identifies how these corals are able to survive in such a dark place.
What factors govern algae's success as 'tenants' of their coral hosts both under optimal conditions and when oceanic temperatures rise?
According to ecotoxicologist from Far Eastern Federal University (FEFU), from the '90s and during 2000s in the tissues of Russian Far Eastern mussels the concentration of organochlorine pesticides (OCPs) that had been globally used in agriculture in the mid-20th century has increased about 10 times. OCPs pollute and affect badly the ecosystems of the Sea of Japan, the Sea of Okhotsk, and the Bering Sea. A related review was published in Water Research.
A newly identified genus and species of worm-like, freshwater clam, commonly known as a shipworm, eats rock and expels sand as scat while it burrows like an ecosystem engineer in the Abatan River in the Philippines.
Dominant, non-native plants reduce wetland biodiversity and abundance more than native plants do, researchers report. Even native plants that dominate wetland landscapes play better with others, the team found.
In nutrient-poor deep-sea sediments, microbes belonging to the Archaea have outcompeted bacterial microorganisms for millions of years. Their ability to efficiently scavenge dead cells makes them the basal producers in the food chain.
When plants absorb excess light energy during photosynthesis, reactive oxygen species are produced, potentially causing oxidative stress that damages important structures. Plants can suppress the production of reactive oxygen species by oxidizing P700 (the reaction center chlorophyll in photosystem I). A new study has revealed more about this vital process.
