Many bumblebee species are declining at a rapid rate in the United Kingdom and elsewhere. This is commonly attributed to the decline in floral resources that has resulted from an intensification in farming practices. Here we assess growth of nests of the bumblebee, Bombus terrestris, in habitats providing different levels of floral resources. Experimental nests were placed out in conventional farmland, in farmland with flower-rich conservation measures and in suburban areas. Nests gained weight… 
Variability of bumblebee communities (Apidae, Bombini) in urban green areas
The number of bumblebee species in the surveyed green areas (r = 0.7497) was decisive for the arrangement of the mutual similarity of group structure, and green urban areas should be created in a size of at least 30 ha.
Lower bumblebee colony reproductive success in agricultural compared with urban environments
It is shown that urban land use is linked to long-term colony reproductive output in a key pollinator, supporting the theory that urban areas provide a refuge for pollinator populations in an otherwise barren agricultural landscape.
Causes of colony mortality in bumblebees
Insight is provided into the little-studied biology of wild bumblebee nests and factors affecting their survival; collecting similar datasets in the future would enable fascinating comparisons as to how parameters such as nest survival and reproduction are changing over time, and are affected by management interventions for bees.
Bumblebee family lineage survival is enhanced in high-quality landscapes
It is shown that the survival of family lineages from the summer worker to the spring queen stage in the following year increases significantly with the proportion of high-value foraging habitat within 250–1,000 m of the natal colony, providing evidence for a positive impact of habitat quality on survival and persistence between successive colony cycle stages in bumblebee populations.
A comparison of techniques for assessing farmland bumblebee populations
There was no significant correlation between the estimates obtained by the three techniques, suggesting that each technique captured a different aspect of local bumblebee population size and distribution in the landscape.
Colony Development and Reproductive Success of Bumblebees in an Urban Gradient
It is shown that not only bottom-up but also top-down effects are equally important for pollinator population dynamics.
Bumble bee species distributions and habitat associations in the Midwestern USA, a region of declining diversity
Bumble bees (Bombus spp.) are important pollinators, yet rapidly declining globally. In North America some species are thriving while others are nearing extinction. Recognizing subtle differences in
How landscape, pollen intake and pollen quality affect colony growth in Bombus terrestris
The results suggest that woody plant species represent highly important pollen sources for the generalist forager B. terrestris early in the season, indicating that several abundant plant species flowering throughout the bumblebees’ foraging season may cover the colonies’ nutritional needs.
The effect of ecological forest restoration on bumblebees (Bombus spp.) in the boreal forest
Insect pollinators are an important part of biodiversity, yet the number of pollinating insects is declining all over the world. Of all the wild plant species about 80% are reliant on insect


The Value of Uncropped Field Margins For Foraging Bumblebees
The role of naturally regenerated field margins in providing forage plants on land where nectar resources are otherwise impoverished is examined and the potential role that naturally regenerate field margins could play in the conservation of bumblebee species is discussed.
Bumble Bee Colonization, Extinction, and Reproduction in Subalpine Meadows in Northeastern Utah
The results suggest that the number and diversity of queens that colonize a meadow in early summer is a function of meadow area, and meadow floristics governs within—meadow Bombus species composition and the persistence, ontogeny, and reproduction of bumble bee colonies.
Foraging habitats and foraging distances of bumblebees, Bombus spp. (Hym., Apidae), in an agricultural landscape
A restricted foraging radius might be one important factor of bumblebee species loss and potential pollinator limitation in modern agricultural landscapes, and long‐distance flights ofbumblebee pollinators have to be considered in the present discussion on gene flow from transgenic plant species on a landscape scale.
The foraging behavior of bumblebees is discussed from a comparative standpoint with other bees and in relation to food distribution and availability in the environment.
Flower usage by bumble-bees : a basis for forage plant management
Bumble-bees allocate a disproportionately high percentage of their visits to perennial plants of later successional stages, which could be used to indicate which bumble-bee groups visit particular crops, and to plan vegetation management to favour particular bumblebee species selectively.
Forage for bumble bees and honey bees in farmland: a case study.
The main forage plants important for both long-tongued bumble bee species comprised a seasonal succession of labiates: Lamium album, Stachys sylvatica and Ballota nigra, and probably other plants outside the survey area.
The Distribution and Decline of British Bumble Bees (Bombus Latr.)
Large reductions in the distributional ranges recorded after 1960 were found for two of the biogeographic elements (especially for the Southern Local Species), which have resulted in the emergence of a new Central Impoverished Region covering 23 vice-counties in Central England.

A landscape‐scale study of bumble bee foraging range and constancy, using harmonic radar
The results support the hypothesis that bumble bees do not necessarily forage close to their nest, and illustrate that studies on a landscape scale are required if the authors are to evaluate bee foraging ranges fully with respect to resource availability.
Effects of habitat isolation on pollinator communities and seed set
It is concluded that habitat connectivity is essential to maintain not only abundant and diverse bee communities, but also plant-pollinator interactions in economically important crops and endangered wild plants.
