Using, Sharing, New Technologies Is Key for Conservation

Oct. 5, 2015 — Scientists estimate that we are losing species at 1,000 times the natural background rate. New technologies are improving conservation efforts by making it easier, faster, and cheaper to monitor ... read more

Cryptic Invasions by Ecological Engineers Conceal Profound Changes in Nature

Oct. 5, 2015 — A new study reveals that the salt marsh plant Spartina alterniflora, which grows on more than 9,000 km of the Atlantic coastline of South America, is not native to the area and was in fact introduced ... read more

Oct. 5, 2015 — The channel, Slo2.2, helps restore neurons' internal electrical state, and so prevents them from firing at too high a frequency for too long, which has the potential to damage the cells. With ... read more

Oct. 5, 2015 — The most common lab animals, rats and mice, can't tell scientists much about speech disorders. However, a new study shows how songbirds, specifically zebra finches, may be able to aid research ... read more

Oct. 5, 2015 — Three new species of trombiculid mites, also known as 'chiggers,' have been discovered in Taiwan, according to a new paper. Chiggers are tiny mites that feed on skin in the larval stage. ... read more

Wild Plants Call to Carnivores to Get Rid of Pests; Could Crops Do the Same?

Oct. 5, 2015 — Rose gardeners have a lot to say about aphids. Some may advise insecticides as a way to manage an infestation, but others will swear by live ladybugs. The latter is more environmental friendly, and ... read more

Trade in Invasive Plants Is Blossoming

Oct. 3, 2015 — Every day, hundreds of different plant species -- many of them listed as invasive -- are traded online worldwide on auction platforms. This exacerbates the problem of uncontrollable biological ... read more

Oct. 2, 2015 — Research into a vast bone bed in western Montana has yielded the most complete life history of any dinosaur ... read more

Oct. 2, 2015 — Scientists have compared the diets of two caterpillar species, expecting the one that exclusively consumed plants containing toxic chemicals would more easily incorporate toxins into its body than ... read more

Oct. 2, 2015 — Scientists have gained new insight into the formation of the spindle, which is the molecular machine that divides up genetic material prior to cell division. Their work focuses on the motor protein, ... read more

Oct. 2, 2015 — Imitation behaviors play a key role in many collective phenomena seen in animals. An analysis of the collective movements of grazing sheep has revealed that sheep alternate slow dispersion phases ... read more

Studying Cardiac Arrhythmias in Nematodes

Oct. 2, 2015 — A simple model using the nematode Caenorhabditis elegans has been developed that can be used to test substances for treating genetically-mediated cardiac arrhythmias. They used the nematode feeding ... read more

Oct. 1, 2015 — A new study has identified a number of genes that are repressed at various time points after memory formation, providing important clues as to how long-term memories are ... read more

Genetic Mutations Linked to a Form of Blindness

Oct. 1, 2015 — Scientists have identified two naturally occurring genetic mutations in dogs that result in achromatopsia, a form of blindness. One of the most promising avenues for developing a cure, however, is ... read more

Oct. 1, 2015 — White-nose syndrome, an invasive skin infection caused by the Pseudogymnoascus destructans fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene ... read more

Oct. 1, 2015 — Local habitat variability in northwest streams can help shield coastal cutthroat trout from the effects of forest harvest and climate change, a new study has ... read more

Oct. 1, 2015 — Variability, such as that seen in movement, is essential both for normal behavior and for longer-term evolution, scientists suggest. Their animal study shows sensory feedback increases the range of ... read more

Oct. 1, 2015 — As easy as it might seem, seeking new species among cultivated plants could be actually quite tricky. While looking into the undescribed orchid, known at the market as 'Big Pink', ... read more

Oct. 1, 2015 — Recent research showed that silicon (Si) is an important nutrient enhancing the endurability of rice plants, however, what controls on Si availability in soils still remain poorly studied. ... read more

The Ecology of Microbial Invasions

Oct. 1, 2015 — Scientists have described how microbial invasions follow the same general pattern as invasions by plant or animal species. This is a clear example of how the microbiological world follows general ... read more
