Tiny globetrotters: Bacteria which live in the Arctic and the Antarctic

Wed, 13 Dec 2017 12:57:38 EST ~ Geoscientists have compared micro-organisms in the polar regions, noting that some bacteria can be found in both regions of Earth. Find out more...

Using drones to estimate crop damage by wild boar

Tue, 12 Dec 2017 14:18:41 EST ~ Growing populations of wild boar (Sus scrofa L.) are causing more and more damage to agricultural land in Europe, requiring hundreds of thousands of Euros in compensation. A new drone-based method allows estimating crop damage in a fast, standardized and objective manner. Find out more...

How fires are changing the tundras face

Tue, 12 Dec 2017 14:18:39 EST ~ Climate change takes a heavy toll on the tundra, increasing the probability of extreme droughts. As a result, the frequency of fires in forests, bogs and even wetlands continues to rise. In addition, the northern areas of the tundra have also become more accessible and negatively impacted by human activities in recent years. Find out more...

Suburban ponds are a septic buffet

Tue, 12 Dec 2017 12:54:04 EST ~ Human waste accounts for a high percentage of nutrients consumed by some animals and plants in suburban ponds, new research indicates. Researchers found that residential, suburban land use is altering the dynamics of the food chain, as well as where nutrients originate and how they move through pond ecosystems. Find out more...

Native fish species at risk following water removal from the Colorado River

Tue, 12 Dec 2017 09:10:42 EST ~ Agriculture and domestic activities consume much of the Colorado River water that once flowed to the Colorado Delta and Northern Gulf of California. The nature and extent of impact of this fresh-water loss on the ecology and fisheries of the Colorado Delta and Gulf of California is controversial. A recent publication reveals a previously unseen risk to the unique local biodiversity of the tidal portion of the Delta. Find out more...

Cyanobacteria in lakes: Risks linked to loss of diversity

Mon, 11 Dec 2017 12:28:18 EST ~ The composition of cyanobacterial communities in peri-alpine lakes has become increasingly similar over the past century. Climate warming and a period of eutrophication have favored in particular potentially toxic species which can adapt rapidly to environmental changes. These are the findings of an study analyzing DNA extracted from sediment cores. Find out more...

African deforestation not as great as feared

Mon, 11 Dec 2017 12:04:25 EST ~ The loss of forests in Africa in the past century is substantially less than previously estimated, an analysis of historical records and paleontology evidence shows. Find out more...

World-first uses satellites, ocean models to explain Antarctic seafloor biodiversity

Mon, 11 Dec 2017 12:04:16 EST ~ In a world-first, a research team has used data collected by satellites and an ocean model to explain and predict biodiversity on the Antarctic seafloor. Find out more...

Novel framework to infer microbial interactions

Mon, 11 Dec 2017 09:07:30 EST ~ Inferring the underlying ecological networks of microbial communities is important to understanding their structure and responses to external stimuli. But it can be very challenging to make accurate network inferences. Scientists now detail a method to make the network inference easier by utilizing steady-state data without altering microbial communities. Find out more...

Study finds ways to avoid hidden dangers of accumulated stresses on seagrass

Fri, 08 Dec 2017 09:56:01 EST ~ A new study has found ways to detect hidden dangers of repeated stresses on seagrass using statistical modelling. The research found cumulative maintenance dredging which affected the light on the sea floor increased risks on seagrass survival. It found, globally, seagrass meadows can be at risk of collapse from accumulated effects of repeated dredging and natural stress. Find out more...
