Understanding the Diet of Endangered Killer Whales can Help Focus on Recovery Efforts

Endangered Southern Resident killer whales prey on a diversity of Chinook and other salmon. The stocks come from an enormous geographic range as far north as Alaska and as far south as California's Central Valley, a new analysis shows.

Pesticide Residues can Negatively Affect Organic Farms for Decades

Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after switching to organic management.

Tundra Plant Communities Respond Similarly to Microclimate, Study Shows

Researchers are in the search for generalisable rules and patterns in nature. Biogeographer Julia Kemppinen together with her colleagues tested if plant functional traits show similar patterns along microclimatic gradients across far-apart regions from the high-Arctic Svalbard to the sub-Antarctic Marion Island. Kemppinen and her colleagues found surprisingly identical patterns.

Global Catalogue of Ecosystems Launched to Enable Coordinated Conservation Efforts

UNSW and The International Union for the Conservation of Nature (IUCN) have launched the world’s first Global Typology of Ecosystems, the first-ever comprehensive system for classifying and mapping all ecosystems on Earth based on both their functions and composition. The typology allows for more coordinated and effective approaches to conservation management.

Pesticide Hinders the Reproduction of Ground-Nesting Bees

An insecticide used to control pest infestations on squash and pumpkins significantly hinders the reproduction of ground-nesting bees -- valuable pollinators for many food crops, a new University of Guelph study has revealed.

Warming of Atlantic Coastal Waters may Enhance the Spread of Invasive Blue Catfish

A study by researchers at William & Mary's Virginia Institute of Marine Science suggests that continued warming of Atlantic coastal waters may enhance the spread of invasive blue catfish within the Chesapeake Bay and other estuaries along the U.S. East Coast.

Decline in Emergent Insects Appears to be Driven by Pollution of Water Bodies

A new study shows that a widespread decline in abundance of emergent insects - whose immature stages develop in lakes and streams while the adults live on land - can help to explain the alarming decline in abundance and diversity of aerial insectivorous birds (i.e. preying on flying insects) across the USA.

OU Researchers Identify the Limits and Insufficiency of Major Greenhouse Emission Database

A University of Oklahoma-led study published in 2020 revealed that both area and plant growth of paddy rice is significantly related to the spatial-temporal dynamics of atmospheric methane concentration in monsoon Asia, where 87% of the world's paddy rice fields are situated.
