How well corals respond to climate change could depend in part on the already scarce amount of iron available in their environment, according to a new study led by Penn State researchers.
Marine biologists studying the genetic structure of the Humboldt squid population found it is vulnerable to overfishing by fleets on its migration path.
Experts who study animal pheromones have traced the evolutionary origins of genes that allow mice, rats and other rodents to communicate through smell. The discovery is a clear example of how new genes can evolve through the random chance of molecular tinkering and may make identifying new pheromones easier in future studies. The results represent a genealogy for the exocrine-gland secreting peptide (ESP) gene family.
Life on Earth is all about strategies for survival, with every organism developing behaviors and bodies that maximize chances of staying alive and reproducing while minimizing the likelihood of being injured or eaten.
Decades of data allow researchers at the NOAA Northeast Fisheries Science Center to look at predator-prey interactions in a different way: among multiple species throughout the water column. They have developed an unusually rich picture of who is eating whom off the Northeastern United States.
European wildcats, thought to be extinct 50 years ago in the Jura mountains, have since recolonised part of their former territory. This resurgence in an area occupied by domestic cats has gone hand-in-hand with genetic crosses between the two species. A team of biologists from the University of Geneva modelled the interactions between the two species and predict that hybridisation will entail the irreversible genetic replacement of wildcats.
The water crisis in Flint, Michigan, brought much-needed attention to the problem of potentially toxic metals being released from drinking water distribution pipes when water chemistry changes. Now, researchers reporting in ACS' Environmental Science & Technology have investigated how hexavalent chromium, known as Cr(VI), can form in drinking water when corroded cast iron pipes interact with residual disinfectant. Their findings could suggest new strategies to control Cr(VI) formation in the water supply.
A new University of Washington study uses passive data from a fishing technology company to model the movement of anglers and predict where aquatic invasive species may be spreading.
The environment in the Cordell Bank National Marine Sanctuary off the coast of San Francisco is not a refuge from the noise generated by ship traffic, the first underwater marine acoustic study of the region has shown.
Their scientific name is "Parazoanthus axinellae" and they are among the most fascinating corals of the Mediterranean Sea. A genetic analysis suggests they may belong to two different species and, therefore, there could be two types of cluster anemone. Researchers claim this may lead to more effective conservation strategies against the negative impact of climate change on this sea population
