An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus in Peru. [PDF]
Ecol Evol, 2023 We analyzed floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. tarmicus along a steep elevational gradient in Peru. Results show floral traits and pollinator assemblage variation along the elevational gradient. We examined our results considering two hypotheses: (1) local adaptation to different bee assemblages ...

Evolution of five environmentally responsive gene families in a pine-feeding sawfly, Neodiprion lecontei (Hymenoptera: Diprionidae). [PDF]
Ecol Evol, 2023 We examine the predictability of gene family size changes in the pine tree specialist Neodiprion lecontei. Overall, our results are consistent with predictable gene family expansions and contractions in response to novel selection pressures. Abstract A central goal in evolutionary biology is to determine the predictability of adaptive genetic changes ...

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests. [PDF]
New PhytolHummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Effects of landscape, resource use, and body size on genetic structure in bee populations. [PDF]
Ecol EvolQuantifying genetic structure and levels of genetic variation are important to predicting the ability of populations to persist in human‐altered landscapes and adapt to future environmental changes. We assessed genetic diversity and genetic structure for seven Euglossine bee species that vary in resource specialization and body size.

Large carpenter bees show high dispersal in a tropical semi-arid region susceptible to desertification. [PDF]
Ecol EvolThis study examines the genetic status of native carpenter bees in a Brazilian region vulnerable to desertification. Employing a population genomic approach, we found low genetic diversity with high homogeneity across populations, even over distances exceeding 300 km.

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