Substantial genetic divergence and lack of recent gene flow support cryptic speciation in a colour polymorphic bumble bee (Bombus bifarius) species complex
<p>Phenotypic polymorphism can constitute an inherent challenge for species delimitation. This issue is exemplified in bumble bees (<i>Bombus</i>), where species can exhibit high colour variation across their range, but otherwise exhibit little morphological variation to distinguish them from close relatives. We examine the species status of one of the most abundant North American bumble bees, <i>Bombus bifarius</i> Cresson, which historically was comprised of two major taxa, <i>bifarius</i> <i>s.s.</i> (<i>sensu stricto</i>) and <i>nearcticus</i>. These sublineages are recognized primarily by red and black variation in their mid-abdominal coloration, however, a continuum from black (<i>nearcticus</i>) to red (<i>bifarius s.s.</i>) variation has led to their historic synonymisation. Integrating mitochondrial and nuclear data and whole-genome sequencing, we reveal a high level of both mitochondrial and nuclear divergence delimiting two morphologically cryptic species – the red <i>bifarius s.s.</i> and the color variable (black to red) <i>nearcticus</i>. Population genomic analysis supports an absence of recent genomic admixture and a strong population structure between the two clades even in sympatry. Species distribution models predict partially differentiated niches between the genetically-inferred clades with annual precipitation being a leading differentiating variable. The<i> bifarius</i> <i>s.s. </i>lineage also occupies significantly higher elevations, with regions of sympatry being among the highest elevations in <i>nearcticus</i>. Our data also support a subspecies-level divergence between the broadly distributed <i>nearcticus</i> and the island population <i>vancouverensis</i>. In this paper, we formally recognize the two species, <i>Bombus</i> <i>bifarius</i> Cresson and <i>Bombus</i> <i>vancouverensis </i>Cresson, the latter including the subspecies <i>B. vancouverensis vancouverensis</i> <b>comb. n.</b> and <i>B. vancouverensis nearcticus</i> <b>comb. n</b>., with <i>vancouverensis </i>the name bearer due to year priority.</p> <p> </p>
Data from: Influence of preexisting preference for color on sampling and tracking behavior in bumble bees
Animals reduce uncertainty in their lifetime by using information to guide decision making. Information available can be inherited from the past or gathered from the present. Therefore, animals must balance inherited biases with new information that may be in conflict with those potential biases. In our study, we set up color pairings such that an arbitrarily chosen focal color, human-orange, would result in an inherent bias in comparison to three other colors tested resulting in equal, medium, and strong preference differences. We chose color pairings through a series of preferences tests across 8 colonies of bumblebees. We subsequently used these pairings with rewards that varied in quality (good or bad states) and consistency (steady and fluctuating) in order to investigate how inherited biases affect the foraging choices of bumblebees when new information is gathered. We found that the pre-existing color biases within our bees were only maintained when the reward associated with those colors was steady, even if paired with mediocre sugar concentrations. When maintained, we observed that other aspects of bee choice also reflected this bias, including increased sampling for the preferred color and an increased likelihood of choosing that color in a subsequent choice. Thus, environmental change and reward differences interact with the level of pre-existing bias to determine whether inherited information is more heavily weighted than newly gathered information, and even a strong pre-existing bias can be quickly erased with experience under some conditions.

Introduced honey bees increase host plant abundance but decrease native bumble bee species richness and abundance
<p>Long-term variation in the population density of introduced honey bees (<em>Apis mellifera)</em> has been shown to be associated with variations in floral traits in alpine lotus (<em>Saussurea nigrescens</em>). However, it remains to be determined whether a high density of honey bees affects the abundance of nectariferous plants and the species richness and abundance of native bumble bees. We predicted that a high density of introduced honey bees lasting three decades would decrease the species richness and abundance of native bumble bees but increase the abundance of honeybee host plant species. Here, the field experiments were conducted to examine the diversity of nectariferous plants and native bumble bees along the typical gradients of honey bee density (high density of honey bee at close apiary and low density of honey bee at distant of apiary). We investigated nectariferous plant abundance, floral and seed traits, bumble bee species richness and abundance at sites with either a high or low honey bee density in an alpine meadow. Our results demonstrated that an increased population of introduced honey bees was associated with increased host plant abundance and flower/capitula number per plant but decreased nectar volume per flower, seed mass, species richness and abundance of native bumble bees. The bumble bee visitation rate was positively correlated with nectar volume per flower at sites close to and far from apiaries. The honey bee visitation rate was positively correlated with flower/capitula number per plant at sites close to apiaries and nectar volume per flower at sites far from apiaries. Seed mass was negatively correlated with nectariferous plant abundance. Our findings showed that introduced honey bees decreased the species richness and abundance of native bumble bees, attributed to evolutionary decrease nectar resources among honey bee host plant species, but increased the abundance of nectariferous plants, attributed to the production of many small seeds by plants. This suggests that long-term high-density beekeeping affects the biodiversity of honey bee host plants and native bumble bees. Our results provide new insights into the mechanisms of maintaining the biodiversity of nectariferous plants and native bumble bees.</p>
