Scientists have discovered that milkweed butterflies harass, subdue, and subsequently feed on live, dead, and dying caterpillars belonging to other milkweed butterflies.

A series of recent research papers from a McGill-led team has found that the herbicide glyphosate—commonly sold under the label Roundup—can alter the structure of natural freshwater bacterial and zooplankton communities.

New research finds evidence of paternal care in a cephalopod, with male bigfin reef squids helping female squids find a suitable place to lay their eggs.

New research shows how the body condition of endangered Southern Resident killer whales reflects changes in Chinook salmon numbers in the Fraser River and the Salish Sea.

A new study finds that wing morphology and flight efficiency are critical factors in a bird’s ability to move to a new breeding place.

Biological diversity in the Appalachians is severely threatened by mountaintop coal mining, according to a study in the September 2021 issue of the journal Ecological Applications.

This month Colorado State University’s Dennis Ojima became president of the governing board of the Ecological Society of America.

(August 23, 2021) – The San Nicolas Island fox, a subspecies of the Channel Island Fox only found on the most remote of California’s eight Channel Islands, is at a low risk of extinction, new research published last week in Ecosphere shows.

A research team from the Institute of Applied Ecology of the Chinese Academy of Sciences found that found that two grassland sites in Inner Mongolia differed markedly in their aboveground net primary production responses to soil moisture, with greater sensitivity at the more arid site.

Logged forests near regional and rural towns and settlements are at increased risk of increased fire severity, new research from The Australian National University shows.

Researchers at the University of Bonn and the University of South-Eastern Norway find that potential consequences of climate change are extremely dependent on the specific location of the plants, and that deciduous species in particular will benefit from warming.

A new study published in Ecosphere shows how narwhals can be detected via infrared flukeprints from aerial survey imagery.

Scientists from the University of Hong Kong, along with colleagues in the UK and the USA, found that forest regeneration is critical to mitigating the increasing effects of extreme hot events for species survival.

A new study shows that coastal marshes are vulnerable to erosion caused by rising seas, pounding waves, and tidal flows, and that in some cases, these vulnerabilities are made worse by superabundant crabs on tidal creeks.

Results of a new study by ecologists at the University of Massachusetts Amherst show that 1,330 nurseries, garden centers and online retailers are still offering hundreds of invasive plant species as ornamental garden plants. This includes 20 species that are illegal to grow or sell nationwide.

For perhaps the first time ever, researchers have mapped out the true extent of habitat loss for salmon in the Lower Fraser River, one of the most important spawning and rearing grounds for Pacific salmon in British Columbia.

New research led by UC Santa Barbara and the University of Washington looking at the longer-term future of wildfires under scenarios of increased temperature and drought, using a model that focuses on the eastern California forests of the Sierra Nevada, finds that there will be an initial roughly decade-long burst of wildfire activity, followed by recurring fires of decreasing area.  

Losses of important eelgrass meadows in western Sweden since the 1980s have led to considerable bottom erosion and the release of carbon and nitrogen; says a new paper published in Ecosphere.

A team of researchers headquartered at the University of Massachusetts Amherst has recently discovered that fear plays an important, unrecognized role in the underdevelopment, and increased vulnerability, of backyard songbirds.
