Marine food webs and biogeochemical cycles react very sensitively to the increase in carbon dioxide (CO2) - but the effects are far more complex than previously thought. This is shown in a study published by a team of researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel in the journal Nature Climate Change. Data were combined from five large-scale field experiments, which investigated how the carbon cycle within plankton communities reacts to the increase of CO2.
Where are small marine animals most vulnerable to getting eaten? In a new study published in Proceedings of the National Academy of Sciences Oct. 26, scientists sketched the first global "BiteMap" showing where the ocean's mid-sized predators are most active. By fishing with dried squid baits called "squid pops," they discovered rising temperatures can shape entire communities of predators and have potential impacts lower down the food web.
Study using biomimetic fish-like robots shows that swimming closely together offers fish hydrodynamic benefits - research project with participation from University of Konstanz researchers provides first experimental validation of an answer to an old question.
MIAMI--As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true for humans but corals too, which are in an ongoing battle to ward off deadly diseases spreading on a reef.
The research team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous research has found.
Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
UC assistant professor Latonya Jackson conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.
The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.
Sponges are filter feeders that live on particulate matter -- but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. They can therefore serve as useful bioindicators of the health of marine ecosystems.
For decades, the front lobe of the pituitary was thought to be an evolutionary development that arose in vertebrates from a particular type of embryonic structure located in the ectoderm. USC researchers now present evidence that, in some vertebrates, the endoderm also forms part of the pituitary's front lobe. Findings from the study suggest that the gland may have a longer evolutionary history than previously thought.
