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 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.
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.
A research team led by New York University professor Maurizio Porfiri put forth a robotics-based study to control information flow in predator-prey interactions, as well as test the validity of transfer entropy when attempting to understand causal influences of the system. They report their findings this week in the journal Chaos, from AIP Publishing.
Canada's current wetland protection efforts have overlooked how the environment naturally protects fresh-water resources from agricultural fertilizer contaminants.
In the intertidal zone, one of the most physically stressful habitats on Earth, Porphyra umbilicalis -- laver or Atlantic nori -- and its ancestors have survived and thrived. Now the sequencing of the P. umbilicalis genome has revealed the unexpected reasons for its ability to successfully compete.
