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 ...

Influence of social lifestyles on host-microbe symbioses in the bees. [PDF]

Ecol Evol, 2023
Microbiome diversity in bees from various social lifestyles and taxa was investigated using cloud computing and publicly available transcriptomic data. Results show that bacterial communities in bees are influenced by host location, phylogeny, and social lifestyle, with more complex bee societies hosting more diverse microbes.

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 ...

Effects of landscape, resource use, and body size on genetic structure in bee populations. [PDF]

Ecol Evol
Quantifying 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.

Gene Flow Across Large Distances in the Cavity-Nesting Wasp <i>Deuteragenia subintermedia</i> in a Central European Forest. [PDF]

Ecol Evol
Retention forestry is widely considered a promising approach to conserve forest biodiversity, and beneficial effects of more heterogeneous forest structure have been shown for several taxa. However, it is often unclear if the approaches taken locally can provide connectivity for specimens over the landscape or if they lead to “biodiversity islands ...

Pollen Analysis of the Post-Emergence Residue of Euglossa Bees (Apidae: Euglossini) Nesting in an Urban Fragment

Sociobiology, 2019
Euglossini bees are considered pollinators of a wide variety of plants in the Neotropical region, but little is known about their floral preferences. In this study, we identified the botanical species used as pollen and nectar sources by three Euglossa ...

Abelhas Euglossina (Hymenoptera, Apidae) coletadas em uma monocultura de eucalipto circundada por Cerrado em Urbano Santos, Maranhão, Brasil Euglossina bees (Hymenoptera, Apidae) collected in an eucalyptus monoculture surounded by Cerrado, Urbano Santos, MA, Brazil

Iheringia: Série Zoologia, 2008
Machos de Euglossina foram coletados por meio de iscas-odores de benzoato de benzila, eucaliptol, eugenol, salicilato de metila e vanilina em uma monocultura de eucalipto circundada por cerrado, no município de Urbanos Santos, Maranhão.

Going up: new altitudinal records of orchid bees (Hymenoptera: Apidae) in the inter-Andean valleys of southern Ecuador and their potential dispersal route

Revista Chilena de Entomología, 2023
Orchid bees are a conspicuous and ecologically important group of insects, commonly distributed at medium and low altitudes in tropical ecosystems. Therefore, new recordings of orchid bees at higher altitudes are interesting.

Large carpenter bees show high dispersal in a tropical semi-arid region susceptible to desertification. [PDF]

Ecol Evol
This 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.
