The fauna in the Antarctica could be in danger due the pathogens humans spread in places and research stations in the southern ocean, according to a study led by the experts Jacob González-Solís, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona, and Marta Cerdà-Cuéllas, from the Institute of Agrifood Research and Technology (IRTA-CReSA).
The ammonia oxidizing archaea, or Thaumarchaeota, are amongst the most abundant marine microorganisms. Yet, we are still discovering which factors allow them to thrive in the ocean: A new publication reveals that marine Thaumarchaeota have a broader metabolism than previously thought.
The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a study published today in Nature Climate Change, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching.
Microbes that provide natural fertilizer to the oceans by 'fixing' nitrogen from the atmosphere into a form useable by other organisms are active in the cold waters of the Bering and Chukchi Seas.
Seals feeding on fish does not decrease fish stocks of Baltic cod, herring and sprat the most -- climate change, nutrient load and fisheries do, shows a new study from Stockholm University.
One out of three rivers in the Iberian Peninsula has salinization mainly due the impact of agricultural activity and territory urbanization. This environmental problem will affect hydric ecosystems due global warming, the growing use of water and the exploitation of soil natural resources.
How much of a reef's ability to withstand stressful conditions is influenced by the type of symbiotic algae that the corals hosts? New work investigates how the nutrients algae share with their coral hosts varies between species and what this could mean for a coral's ability to survive in a changing climate. They determined that in the wake of a bleaching event, even an algal tenant that's poor provider may be better than no provider.
New research has reported effective conservation strategies that can mitigate the impacts of climate warming on sea turtle nesting success.
Industrial fisheries are starving seabirds like penguins and terns by competing for the same prey sources. Seabirds are now the most threatened bird group.
Geckos are amazingly agile. In addition to running across land and up trees, the animals can prance across the surface of water. A new study reveals how they do it.
