The Blob Returns
In the autumn of 2013, Nicholas Bond, who was then the State Climatologist for the state of Washington, first detected a large (500 miles wide x 300 feet deep), circular body of sea water which had not cooled as expected and was 2 to 3 degrees warmer than the rest of the surrounding Pacific Ocean. By mid-2014, this unnaturally warm patch of ocean had grown to 100 miles long x 1000 miles wide x ...

Living on the edge: Populations of two zooplankton species living closer to agricultural fields are more resistant to a common insecticide
Ecological communities across the globe are exposed to a diversity of natural and anthropogenic stressors and disturbances that can lead to community‐wide impacts. Contaminants are a group of anthropogenic disturbances that are ubiquitous in the environment and can trigger trophic cascades, increased susceptibility to pathogens, reduced biodiversity, and altered ecosystems. In these ...

Ecological characteristics of plankton and aquatic vegetation in Lake Qiluhu
Investigations of the phytoplankton, zooplankton, zoobenthos and aquatic vegetation in Lake Qiluhu were carried out in February, 2009. Over the whole lake, 13 sampling sites were set up for the analysis of phytoplankton and zooplankton, and 22 profiles for the collection of macrophytes and zoobenthos. In the survey, 7 phyla, 65 algae species were identified. The average abundance of ...

AHPN inferences based on behavior of Vibrio bacteria
Summary: Vibrio parahaemolyticus, the pathogen associated with acute hepatopancreatic necrosis (AHPN), has both toxic and benign strains. It inhabits the stomachs of shrimp in a biofilm, which protects it from antibiotics and other treatments. As with V. cholera, V. parahaemolyticus tolerates a range of salinities, pH and temperatures. Both species readily piggyback on marine plankton and may be ...
