When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals' stress.
A study conducted by a UPV/EHU-University of the Basque Country research group within the framework of the European Globaqua project proposes going beyond the study of river ecosystems and incorporating into the studies routinely carried out a set of processes that regulate not only the fluxes of matter but also the fluxes of energy within an ecosystem. In a recently published paper, the group is proposing a new working framework to study the status of rivers.
Solutions to climate change, and particularly its effects on the ocean, are needed now more than ever. Coral bleaching caused by climate change is a huge threat to coral reefs. Recent extreme bleaching events have already killed corals worldwide and permanent destruction of reefs is projected within the century if immediate action is not taken. However, genetically engineering a group of microalgae found in corals may enhance their stress tolerance to ocean warming and save coral reefs.
The preferred fodder of horses is grass. This is true for domestic horses and wild horses in the Gobi Desert. Researchers from Vetmeduni Vienna found out through tail hair analysis that before their extinction in the wild Przewalski's horses had been on a different diet than today. Thanks to improved societal attitude, the horses have now access to richer pastures. In former times, the wild horses were hunted and chased away. Published in Scientific Reports.
The world's most extensive study of a major stormfront striking the coast has revealed a previously unrecognised danger from climate change: as storm patterns fluctuate, waterfront areas once thought safe are likely to be hammered and damaged as never before.
The unique system of hydraulic control of fins discovered in tuna indicates a new role for the lymphatic system in vertebrates. This natural mechanism may inspire designs for new 'smart' control surfaces with changeable shape and stiffness for both air and underwater unmanned vehicles.
Every day, humans pick up on idiosyncrasies such as slow drawls, high-pitched squeaks, or hints of accents to put names to voices from afar. This ability may not be as unique as once thought, researchers report on July 20 in Current Biology. They find that unlike all other non-human mammals, northern elephant seal males consider the spacing and timing of vocal pulses in addition to vocal tones when identifying the calls of their rivals.
Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species.
Researchers have identified a genetic difference in domesticated dogs and wolves that could explain the canines' contrasting social interaction with humans.
Shark feeding habits are helping scientists identify marks on human bones found in the ocean. By analyzing shark scavenging behavior, the University of Florida's C.A. Pound Human Identification Laboratory identified which marks were left behind by sharks, what species of sharks made the marks and where the feedings might have occurred.
