How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

• Behavior and organization of social groups is thought to be vital to the functioning of societies, yet the contributions of various roles within social groups toward population growth and dynamics have been difficult to quantify. A common approach to quantifying these role‐based contributions is evaluating the number of individuals conducting cer...

Life history trade‐offs are ubiquitous in nature. Life history theory posits that these trade‐offs arise from individuals having limited resources to allocate toward all vital functions, such as survival, growth and reproduction. These trade‐offs position most species along a slow‐fast life history continuum, where individuals with slow life histor...

For bumble bees and other social organisms, colonies are the functional unit of the population rather than the individual workers. Estimates of bumble bee nest density are thus critical for understanding population distribution and trends of this important pollinator group. Yet, surveys of bumble bee nests and other taxa with sessile life stages ra...
Article
A rapidly changing climate has the potential to interfere with the timing of environmental cues that ectothermic organisms rely on to initiate and regulate life history events. Short‐lived ectotherms that exhibit plasticity in their life history could increase the number of generations per year under warming climate. If many individuals successfull...

Matrix population models are widely used to assess population status and to inform management decisions. Despite existing theories for building such models, model construction is often partially based on expert opinion. So far, model structure has received relatively little attention, although it may affect estimates of population dynamics. Here, w...

For bumble bees, colonies (not individual workers) are the functional unit of the population. Estimates of colony density are thus critical for understanding population distribution and trends of this important pollinator group. Yet, surveys of bumble bee colonies and other taxa with sessile life cycle states rarely account for imperfect detection....
Article
Size‐number trade‐offs in reproduction are commonly observed in nature. Bumblebee (Bombus spp.) colonies produce workers that vary considerably in size. This variation suggests that colonies face potential size‐number trade‐offs when producing workers. Here, we estimated size‐based vital rates of Bombus vosnesenskii workers using colonies reared fr...

Management of invasive populations is typically investigated case‐by‐case. Comparative approaches have been applied to single aspects of management, such as demography, with cost or efficacy rarely incorporated. We present an analysis of the ranks of management actions for 14 species in five countries that extends beyond the use of demography alone...

My bumble bee project is investigating size-based trade-offs among workers of the yellow-faced bumble bee (Bombus vosnesenskii). Bumble bee workers vary significantly in body size (up to 10 fold difference in mass), and tasks within colonies are usually allocated based on worker size. However, the literature suggests larger workers are better at most tasks. My research is investigating the size-number trade-offs in producing workers of various sizes to understand why colonies maintain size variation.
