Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Silene, a versatile model system: from sex and genome evolution to ecology and speciation

New Phytologist, Volume 250, Issue 6, Page 3613-3630, June 2026.
Summary Fundamental and applied research in evolutionary biology benefits from the use of model systems in which approaches from disparate disciplines can be integrated. Here, we review recent progress in evolutionary research on the long‐standing model system Silene, a large genus with a well‐resolved phylogeny and newly available, expanded genomic ...

Pollinator conservation paradox: Exotic wildflowers provision native pollinators under anthropogenic changes

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Invasive wildflowers pose a conservation paradox: While they often reduce the diversity and abundance of native wildflowers, they can provide resources for native pollinators, including imperiled species. Previous work has framed wildflower invasions as outcomes of global change, but less is known about how interacting anthropogenic drivers ...

High Elevation Refugia for Bombus terricola (Hymenoptera: Apidae) Conservation and Wild Bees of the White Mountain National Forest

Journal of Insect Science, 2017
Many wild bee species are in global decline, yet much is still unknown about their diversity and contemporary distributions. National parks and forests offer unique areas of refuge important for the conservation of rare and declining species populations.

Indirect effects of herbicide use on the Bombus community mediated through changes to shrub and forb communities

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Pesticides are used around the world to control and suppress undesirable species. In many cases the direct effects of pesticides are well understood and characterized, describing how environments are likely to be altered. However, these direct effects are likely to cause other species to respond to ecosystem alteration. For example, herbicides

Proteomic Characterization of the Venom of Five Bombus (Thoracobombus) Species

Toxins, 2017
Venomous animals use venom, a complex biofluid composed of unique mixtures of proteins and peptides, to act on vital systems of the prey or predator. In bees, venom is solely used for defense against predators.

Bumblebees gain fitness through learning [PDF]

, 2007
Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning

Fire modulates the structural drivers and functioning of individual‐based plant‐pollinator networks

Journal of Ecology, Volume 114, Issue 5, May 2026.
Ecological drivers that shape (positively or negatively) the plant‐pollinator network and determine plant fitness, both before and after a fire. Abstract Fire is a natural phenomenon that shapes ecosystems, but climate change and human activities have increased its frequency and magnitude, disrupting essential ecosystem services like pollination ...

Fatty Acids from Pool Lipids as Possible Precursors of the Male Marking Pheromone in Bumblebees

Molecules, 2014
Triacylglycerols (TGs) stored in the fat bodies of bumblebee males have a species-specific composition. The striking structural similarities between TG fatty acids (FAs) and components of the male marking pheromone in certain species led to the ...
