Last year's extreme snowfall wiped out breeding of Arctic animals and plants

In 2018, vast amounts of snow were spread across most of the Arctic region and did not melt fully until late summer, if at all. Researchers documented the consequences of this extreme weather event at Zackenberg, Northeast Greenland by extensively monitoring all components of the local ecosystem for more than 20 years, allowing them to compare life in the extreme year of 2018 to other, more 'normal,' years.

Two new porcelain crab species discovered

Two new symbiotic porcelain crab species have been described. One of them, from the South China Sea of Vietnam, inhabits the compact tube-like shelters built by the polychaete worm with other organisms. The other inhabits the intertidal vermetid snail formations in the Colombian Caribbean.

Rare 'itinerant breeding' behavior revealed in California bird

Only two bird species have ever been shown to undertake what scientists call 'itinerant breeding': nesting in one area, migrating to another region, and nesting again there within the same year, to take advantage of shifting food resources. However, new research provides strong evidence of this rare behavior in a third bird — the Phainopepla, a unique bird found in the southwestern US and the northernmost member of an otherwise tropical family.

Lakes worldwide are experiencing more severe algal blooms

The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Researchers used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents.

The impact of human-caused noise pollution on birds

Anthropogenic noise pollution (ANP) is a globally invasive phenomenon impacting natural systems, but most research has occurred at local scales with few species. Researchers in this study investigated continental-scale breeding season associations with ANP for 322 bird species to test whether local-scale predictions are consistent at broad spatial extents for an extensive group of North American bird species in the continental United States.

Secrets to climate change adaptation uncovered in the European corn borer moth

Biologists have found two genes that may permit some insect species to survive climate change by adjusting their biological annual clocks while others succumb. The researchers looked at the European corn borer moth and pinpointed variation in two circadian clock genes — per and Pdfr — that enable different populations of the moth to adapt their transitions to longer or shorter winters.

A unique study sheds light on the ecology of the glacial relict amphipod Gammaracanthus lacustris

The glacial relict amphipod Gammaracanthus lacustris only occurs in deep and cold waters. A new study produced new information on the life cycle and ecology of this rare amphipod. G. lacustris is adapted to cold water and would probably not survive in rising water temperatures due to climate change.
