Arctic inland waters emit large amounts of carbon
Geoscientist Erik Lundin shows in his thesis that streams and lakes of Northern Sweden are hotspots for emissions of carbon dioxide and methane into the atmosphere. Erik defends his findings at Sweden's Umeň University on Friday, Jan. 31.

Large and in charge
A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height offered a distinct advantage to the earliest forms of multicellular life.

Bats use water ripples to hunt frogs
As the male tungara frog serenades females from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats. He will stop calling if he sees a bat overhead, but ripples continue moving for several seconds after the call ceases. In the study, researchers found evidence that bats use echolocation to detect these ripples and home in on a frog.

Study says sharks/rays globally overfished
One quarter of the world's cartilaginous fish, namely sharks and rays, face extinction within the next few decades, according to the first study to systematically and globally assess their fate. The International Union for Conservation of Nature's Shark Specialist Group, co-chaired by Nick Dulvy, a Simon Fraser University Canada Research Chair in Marine Biodiversity and Conservation in British Columbia, conducted the study. It was published in eLife journal today.

War on lionfish shows first promise of success
It may take a legion of scuba divers armed with nets and spears, but a new study confirms for the first time that controlling lionfish populations in the western Atlantic Ocean can pave the way for a recovery of native fish. Scientists say there's finally a way to fight back.

Predatory organisms at depth
In deep, old and nutrient-poor marine sediments there are up to 225 times more viruses than microbes. In such extreme habitats viruses make up the largest fraction of living biomass and take over the role as predators in this bizarre ecosystem.

Are anti-poaching efforts repeating the mistakes of the 'war on drugs'?
Illegal poaching, fueled by the demand for alternative "medicines" and luxury goods in Asian markets, continues unabated. In response unprecedented levels of funding are being invested in enforcement, while events such as China's public burning of confiscated ivory, serve to publicize the problem.

Micropredators dictate occurrence of deadly amphibian disease
Researchers have made progress in understanding the distribution of the deadly amphibian chytrid pathogen. In some regions, the deadly impact of the pathogen appears to be hampered by small predators, naturally occurring in freshwater bodies. These micropredators may efficiently reduce the number of free-swimming infectious stages (zoospores) by consuming them. This natural behavior will reduce the infection pressure on potential amphibian hosts. These results were published in the Cell Press journal Current Biology.

Curtin researchers to hide our splashes from sharks
Curtin University researchers will attempt to "mask" the noise of swimmers from sharks after receiving a grant from the State Government's Shark Hazard Mitigation Strategy. The project will first look at characterizing noises produced from swimming, surfing and kayaking that are detectable by a number of large shark species. Researchers will then compare shark behavior when the human noises are detectable to when they are masked, to see if masking typical swimmer noises can be effective at disrupting detection of humans.

Source of Galapagos eruptions is not where models place it
Images gathered by University of Oregon scientists using seismic waves penetrating to a depth of 300 kilometers have found an anomaly that likely is the volcanic mantle plume of the Galapagos Islands. It's not where geologists and computer modeling had assumed.

Frog fathers don't mind dropping off their tadpoles in cannibal-infested pools
Given a choice, male dyeing poison frogs snub empty pools in favor of ones in which their tiny tadpoles have to metamorphose into frogs in the company of larger, carnivorous ones of the same species. These are seemingly strange decisions, given how often cannibalism involving a large tadpole eating a smaller one takes place in natural pools, writes Bibiana Rojas of the University of Jyvaskyla in Finland in Springer's journal Behavioral Ecology and Sociobiology.

The water cycle amplifies abrupt climate change
During the abrupt cooling at the onset of the so-called Younger Dryas period 12680 years ago changes in the water cycle were the main drivers of widespread environmental change in western Europe. Thus, the regional impacts of future climate changes can be largely driven by hydrological changes, not only in the monsoonal areas of the world, but also in temperate areas.

Keeping whales safe in sound
The International Union for the Conservation of Nature is intensifying global efforts to safeguard whales and other marine species from the harms of powerful noise used in seismic seafloor surveys by the oil and gas industry and others. The impetus is the newly-documented success of harm mitigation measures used in a study near critical whale feeding grounds around energy resource-rich Sakhalin Island, Russia, just north of Japan.

Poison-breathing bacteria may be boon to industry, environment
Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in California, and their experiments with this unusual organism show that it may one day become a useful tool for industry and environmental protection.

A new toad from the 'warm valleys' of Peruvian Andes
A new species of toad was discovered hiding in the leaf litter of montane rain forest known as Peruvian Yungas ("warm valley" in translation). Like many other toads (family Bufonidae) inhabiting the forest floor, the new species Rhinella yunga has a cryptic body coloration resembling decaying leaves in the area, securing perfect camouflage but making morphological identification of species hard for scientists. The study was published in the open access journal ZooKeys.
