The ghosts of harvesting can haunt today’s conservation efforts. Conserving or overharvesting a renewable resource like fish or other wildlife is often determined by habits and past decisions, according to a Rutgers-led study that challenges conventional expectations that the collapse of fast-growing natural resources is unlikely.
A "gold rush" of seabed mining could lead to unprecedented damage to fragile deep-sea ecosystems, researchers have warned.
Texas State University researchers have contributed to groundbreaking research that has identified the formation of a new sex chromosome in Xiphophorus fish.
After going missing on Christmas Day five years ago, deep ocean measuring equipment belonging to the UK’s National Oceanography Centre (NOC) has just been found on a beach in Tasmania by a local resident after making an incredible 14,000 km journey across the ocean.
Researchers from FSU’s Department of Earth, Ocean and Atmospheric Science suggest that projected increases in air temperatures, rainfall inundation and blistering solar radiation could significantly reduce hawksbill hatching success at a selection of major nesting beaches.
New research finds that the combined effects of land use and climate change are resulting in increased salinity levels in rivers and streams, further highlighting an emerging threat to freshwater resources, biodiversity and ecosystem functions across the United States.
Choosing a place to call home is one of the most consequential choices a coral can make. In the animal's larval stage, it floats freely in the ocean--but once it settles down, it anchors itself permanently to the rocky substrate of a reef, and remains stuck there for the rest of its life. Exactly how these larvae choose a specific place to live, however, is largely unclear.
The Government of Argentina has created two massive offshore marine parks in the southwest Atlantic that will help protect the diverse marine life of the Patagonian Sea, according to WCS (Wildlife Conservation Society) and a host of other partners who have worked for years to protect these biodiverse seascapes.
Many fish produce sounds for courtship and mating, navigation, and defending their territories. Scientists analyze these sounds to study their behavior such as reproduction. Since grouper spawning is brief and it takes them a long time to reach sexual maturity, they are vulnerable to overfishing. “Eavesdropping” on them is key to their survival. Researchers have developed a novel acoustic monitoring technique to classify grouper species by their sounds or “grouper calls,” with accuracy of about 90 percent.
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.
Inhabiting a vast network of estuaries along the Atlantic coast, blue crabs are ecologically important and represent one of the valuable and prized fisheries in the United States. Blue crabs spawn in estuaries at a time of year when water-quality issues such as low dissolved oxygen (hypoxia) and low pH (acidification) can be the most persistent and severe. A group from the lab of Christopher Gobler, a professor in the School of Marine Science (SoMAS) at Stony Brook University, investigated the effects of these individual and combined stressors on early life stages of the blue crab. Their study, recently published in PLoS One, provides evidence that larval blue crabs experience increased mortality when exposed to low oxygen and/or low pH conditions at levels routinely found in degraded estuaries.
The largest extinction in Earth’s history marked the end of the Permian period, some 252 million years ago. Long before dinosaurs, our planet was populated with plants and animals that were mostly obliterated after a series of massive volcanic eruptions in Siberia. Fossils in ancient seafloor rocks display a thriving and diverse marine ecosystem, then a swath of corpses.
An update for an internationally vital sea-ice computer model developed at Los Alamos National Laboratory with several collaborating groups, called CICE version 6.0, is being released this week, a timely tool that supports more accurate forecasting of ice occurrence and global climate modeling.
Climate change must no longer be viewed as a "tragedy of the commons", researchers say. December marks the 50th anniversary of the paper that popularized the concept of tragedy of the commons: it argued that individuals will always take advantage of a common resource and so degrade it. A new paper argues that the theory limits the way climate change is viewed.
On 3 December 2018, the laboratory of Professor Axel Meyer, University of Konstanz published new findings of an experimental evolutionary project that ran for 30 years on the genomic mechanisms of sex determination in swordtail fish in the journal "Nature Communications". Dr Paolo Franchini, evolutionary biologist and Junior Research Group Leader at the University of Konstanz is the lead author of this collaboration with the laboratory of Professor Manfred Schartl of the University of Würzburg
When the tiny and invasive spiny water flea began appearing in UW–Madison researchers’ nets in 2009, scientists began to wonder how Lake Mendota, one of the most-studied lakes in the world, went from flea-free to infested seemingly overnight, undetected by trained technicians. A new report published in the journal Ecosphere says Lake Mendota’s story may be the rule, rather than an exception.
New research shows that mussels readily take in microplastic pollution fibers from the ocean but quickly flush most of them out again, according to a study by researchers from Bigelow Laboratory for Ocean Sciences. The findings were published in December's Marine Pollution Bulletin.
Salt-adapted freshwater zooplankton grow 65 percent slower than regular zooplankton. Their slow growth cascades down the food chain in environments polluted with the most commonly found salt, triggering algal blooms.
