Data from: Contrasting effects of land cover on nesting habitat use and reproductive output for bumble bees
<p><span><span><a name="_Hlk64216363">Understanding habitat quality is central to understanding the distributions of species on the landscape, as well as to conserving and restoring at-risk species. Although it is well-known that many species require different resources throughout their life cycles, pollinator conservation efforts focus almost exclusively on forage resources. In this study, we evaluate nesting habitat for bumble bees by locating nests directly on the landscape. We compared colony density and colony reproductive output for <i>Bombus impatiens, </i>the common eastern bumble bee, across three different land cover types (hay fields, meadows, and forests). We also assessed nesting habitat associations for all <i>Bombus</i> nests located during surveys to tease apart species-specific patterns of habitat use. We found that <i>B. impatiens</i> nested under the ground in two natural land cover types, forests and meadows, but found no <i>B. impatiens</i> nests in hay fields. Though <i>B. impatiens</i> nested at similar densities in both meadows and forests, colonies in forests had much higher reproductive output<i>. </i></a>In contrast, <i>B. griseocollis</i> tended to nest on the surface of the ground and was almost always found in meadows. <i>B. perplexis</i> was the only species to nest in all three habitat types, including hay fields. For some bumble bee species in this system, meadows, the habitat type with abundant forage resources, may be sufficient to maintain them throughout their life cycles. However, <i>B. impatiens</i> might benefit from heterogeneous landscapes with forests and meadows. Results for <i>B. impatiens</i> emphasize the longstanding notion that habitat use is not always positively correlated with habitat quality (as measured by reproductive output). Our results also show that habitat selection by bumble bees at one spatial scale may be influenced by resources at other scales. Finally, we demonstrate the feasibility of direct nest searches for understanding bumble bee distribution and ecology. </span></span></p>
