Researchers find that bumblebees’ body size could make them more vulnerable in a warming world

According to new research, the climate crisis may result in more small-bodied bees but fewer bumblebees, with potentially “cascading” implications on plant pollination and ecosystems. Over the course of eight years, scientists in the United States trapped and studied more than 20,000 bees in a region of the Rocky Mountains to see how different varieties […]

Where is the threshold of environmental change that biodiversity can withstand before it is destabilized and collapses planetwide?

Where is the threshold of environmental change that biodiversity can withstand before it is destabilized and collapses planetwide?

Biodiversity. When you hear this word, what do you picture? Iconic animals like African elephants, gray wolves and humpback whales? Or multicolored coral species that make up a reef system? Or bacteria and microbes that regulate nutrients in the soil, or oxygen-releasing phytoplankton that live in the ocean’s sunlit zones? While biodiversity does embrace all […]

EPA plans to allow the use of insecticides devastating to bees and butterflies to continue in America for the next 15 years

Despite steps by the European Union to limit the use of poisons responsible for widespread insect losses, the US Environmental Protection Agency is prepared to allow the use of four of the most harmful compounds to bees, butterflies, and other insects in America for the next 15 years. Despite “ecological hazards of concern, notably to […]
