Ecological partnerships, or mutualisms, are globally widespread, sustaining agriculture and biodiversity. Mutualisms evolve through the matching of functional traits between partners, such as tongue length of pollinators and flower tube depth of plants. Long-tongued pollinators specialize on flowers with deep corolla tubes, whereas shorter-tongued pollinators generalize across tube lengths. Losses of functional guilds because of shifts in global climate may disrupt mutualisms and threaten partner species.

On Thursday, a federal appeals court overturned the EPA's decision to approve marketing of sulfoxaflor, a pesticide that acts like the same neonicotinoids class associated with bee declines.

Landcare Research is opening a survey as an initial means of assessing the causes behind bee colony losses in New Zealand.

Landscape-wide research by former UK government agency on oilseed rape fields in England and Wales shows link between neonicotinoids and honeybee colony losses

It's not exactly an uncommon sentiment to believe that pesticides are causing a lot more environmental harm than big chemical lets on.

No, it isn't the End of Days, but we are likely living during what experts will later refer to as one of the largest extinction events in Earth's history - an unexpected addition to prehistory's "B

Farmers allowed to use two neonicotinoid pesticides on their crop for 120 days despite concerns over serious risk to bees and other pollinators

Anthropogenic declines of animal pollinators and the associated effects on human nutrition are of growing concern. We quantified the nutritional and health outcomes associated with decreased intake of pollinator-dependent foods for populations around the world. The researchers assembled a database of supplies of 224 types of food in 156 countries.

For many species, geographical ranges are expanding toward the poles in response to climate change, while remaining stable along range edges nearest the equator. Using long-term observations across Europe and North America over 110 years, we tested for climate change–related range shifts in bumblebee species across the full extents of their latitudinal and thermal limits and movements along elevation gradients.

The new studies have raised concerns about fungicides: in one, foraging on fungicide-dosed flowers harmed bumblebees.
