Climate change is exacerbating problems like habitat loss and temperatures swings that have already pushed many animal species to the brink. But can scientists predict which animals will be able to adapt and survive? Using genome sequencing, researchers from McGill University show that some fish, like the threespine stickleback, can adapt very rapidly to extreme seasonal changes. Their findings could help scientists forecast the evolutionary future of these populations.
A team of evolutionary biologists has shown that Anolis lizards, or anoles, are able to breathe underwater with the aid of a bubble clinging to their snouts. Some anoles are stream specialists, and these semi-aquatic species frequently dive underwater to avoid predators, where they can remain submerged for as long as 18 minutes. The researchers termed the process 'rebreathing' after the scuba-diving technology.
Scientists help protect sharks by developing aquarium breeding programs that pair up individuals in ways that increase genetic diversity. In a new study in Scientific Reports, scientists undertook the largest-ever effort to artificially inseminate sharks.Their work resulted in 97 new baby sharks, including ones whose parents live on opposite sides of the country and a few that don't have fathers at all.
Fossilised footprint tracks, recently discovered within the Hanna Formation in Wyoming, USA, which have been dated to 58 million years ago, may represent the earliest evidence of mammals gathering by the sea, according to a study published in Scientific Reports. Findings suggest that mammals may have first used marine habitats at least 9.4 million years earlier than previously thought, in the late Paleocene (66-56 million years ago), rather than the Eocene (56-33.9 million years ago).
A new whole genome sequence for the Yap hadal snailfish provides insights into how the unusual fish survives in some of the deepest parts of the ocean. Xinhua Chen of the Fujian Agriculture and Forestry University and Qiong Shi of the BGI Academy of Marine Sciences published their analysis of the new genome May 13th in the journal PLOS Genetics.
A new study, by researchers from Simon Fraser University and the Department of Fisheries and Oceans, reveals the trade-offs of fish biodiversity--its costs and benefits to mixed-stock fisheries--and points to a potential way to harness the benefits while avoiding costs to fishery performance.
While standing dead trees in ghost forests did not release as much greenhouse gas emissions as the soils, they did increase GHG emissions of the overall ecosystem by about 25 percent.
The research, published in special issue of Sustainability that was co-edited by NAU researchers, demonstrates that biodiversity commitments will be key to global freshwater protection.
Using data captured by video cameras and smart accelerometers attached to female elephant seals, Taiki Adachi and colleagues show that the animals spend at least 80% of their day foraging for fish, feeding between 1,000 and 2,000 times per day. The unique glimpse at elephant seal foraging strategy shows how these large marine mammals exploit a unique ocean
A new study sets out guidelines to maximize the benefits of reef restoration, not only for the coral ecosystem, but also to protect local communities from coastal flooding. Researchers simulated waves travelling over different reef profiles at various stages of restoration and found that to reduce the risk of flooding, the upper fore reef and middle reef flat, typically characterized by physically-robust coral species, should be targeted for restoration.
