Movement of nest‐searching bumblebee queens reflects nesting habitat quality

open access: yesEcological Entomology, Volume 47, Issue 5, Page 719-727, October 2022., 2022
We found that nest‐searching Bombus impatiens queens search more thoroughly in land cover types associated with high nest densities (forests and meadows) than low‐quality habitat (hay fields). Our results support the theoretical prediction that animals move in a way that increases time spent in higher‐quality habitat.

Long‐term (1979–2019) dynamics of protected orchid bees in Panama

open access: yesConservation Science and Practice, Volume 3, Issue 12, December 2021., 2021
We gathered quantitative data on 33 species of an intact orchid bee community in lowland forest. Our two studies combined included half the months during 50 years' monitoring. Most species increased or were stable, but the declines included some of the most common and, therefore, unthreatened species.
