There are roughly five times as many recreational fishers as commercial fishers throughout the world. And yet, the needs and peculiarities of these recreational fishers have largely been ignored in international fisheries and conservation policy. An international team of scientists led by Robert Arlinghaus from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries has now presented a five-point plan to bring about reform.
A scientific study describes for the first time the submarine cartography of a high-latitude system in the IBIS channel, which covers tens of kilometres in the northern western area of the Barents Sea, in the Arctic Ocean. This channel is one of the few submarine valleys in polar latitudes that kept its geological architecture during the Last Glacial Maximum (LGM).
Meadows adjacent to high-intensity agricultural areas are home to less than half the number of butterfly species than areas in nature preserves. The number of individuals is even down to one-third of that number. These are results of a research team led by Jan Christian Habel at the Technical University of Munich (TUM) and Thomas Schmitt at the Senckenberg Nature Research Society.
An array of underwater listening lines that detect passing giant Atlantic bluefin tuna previously caught and tagged by scientists has created a new system to monitor these enormous, fast, powerful and lucrative fish in the open ocean. Ten years of research using the technology sheds light on the species' natural mortality as well as migration, important information for sustainable management of their populations.
A global research team including scientists from La Trobe University have identified specific locations within plants' chromosomes capable of transferring immunity to their offspring.
Purdue University researchers have developed a process to remove nearly all traces of oil in produced water.
Honey bee colonies foraging on land with a strong cover of clover species and alfalfa do more than three times as well than if they are put next to crop fields of sunflowers or canola, according to a study just published in Scientific Reports by an Agricultural Research Service scientist and his colleagues.
Modern analytical tools like mass spectrometers can identify many unknown substances, allowing scientists to easily tell whether foods or medicines have been altered. However, the cost, size, power consumption and complexity of these instruments often prevent their use in resource-limited regions. Now, in ACS Central Science, researchers report that they have developed a simple, inexpensive method to identify samples by seeing how they react to a change in their environment.
Irrigation water's E. coli results can differ between labs, test types.
A new model quantifies how forest change affects local surface temperatures by altering sunlight-reflection and evapotranspiration properties, and predicts that Brazilian deforestation could result in a 1.45°C increase by 2050, in a study published March 20, 2019, in the open-access journal PLOS ONE by Jayme A. Prevedello from the Rio de Janeiro State University, Brazil, and colleagues.
