Planting floral resources is a common strategy for increasing the abundance and diversity of beneficial flower-visiting insects in human-modified systems. However, context local area surrounding landscape may affect attractiveness these resource provisioning plots. We compared relative effects urban land-use on bees flowering plants gardens eastern Tennessee, USA. planted four types garden plots at each five different landscapes representing variety land use: 1) Urban Garden, 2) Forage Grassland, 3) Mixed Agriculture, 4) Forest, 5) Organic Farm. Each plot type had fixed plant community one three families (Asteraceae, Fabaceae, Lamiaceae) or mix all three, were replicated sites. concurrently sampled 50 m radius (local area) around found that size display (i.e. visual flowers) flowers did not bee species richness Although there was significant positive association between developed use 2 km gardens, effect small, no relationship area. There differences composition plots, but largest determinants variation bloom. This finding promising anyone wishing to promote pollinator populations by providing more resources.

Abstract Bumblebees (Apidae: Bombus ) are abundant pollinators in Mediterranean habitats; however, interaction networks with plants have not yet been investigated large areas of Italy, including its islands. Here, we analyzed plant-bumblebee through seasonal transects a suburban park and nature reserve Eastern Sicily. After molecular morphological identification bumblebees, built bipartite extracting complementarity, niche overlap, modularity nestedness. In total, sampled 10 the 15 species known from Richness was close to that predicted by accumulation curves, no differences community diversity were found between two sites. At both sites, nested, highly specialized modular, high complementarity low again species-level specialization varied considerably independent sample size. The network topologies suggest possible role local interspecific competition and/or variation among generalist bumblebees. Comparison previously published data revealed more than those continental climate. This suggests possibility increased phenotypic under harsh conditions. vulnerability basin droughts caused climate change calls for detailed studies on pollinator-plant conservation plans.

ABSTRACT We used flowers to explore how ephemeral anthosphere microbiomes differ among flowering plant species and along an urban gradient. Here, we sequenced 16S rRNA for bacteria, ITS1 fungi rbcL DNA from 10 different sampled characterise gradient identify important network interactions. Bacterial fungal flower significantly differed in diversity across species, especially Asteraceae Fabaceae. Across all analyses, four taxa, the bacteria Pantoea Rosenbergiella Alternaria Cladosporium were highly prevalent contributed majority of microbiome composition differences observed between species. These taxa harbour strains or that may be either pathogenic beneficial plants. a land use gradient, community bacterial was stable consistent. Flower‐plant networks confirmed focal families abundance on each flower, with addition Paulowniaceae, suggesting pollinators visiting also visit this family. Our findings reveal are diverse at level encouragingly remain robust against urbanisation.

Abstract Understanding the impacts of urbanization and climate change on organisms has become increasingly critical in ecology conservation as these anthropogenic stressors negatively impact wildlife biodiversity, especially pollinators such bees. We analysed demographic (abundance sex ratio) morphological (body size wing wear) responses to inter‐annual variation four common wild bee species across an urban gradient Toronto, Canada. observed more significant shifts demography with precipitation than urbanization, diverse patterns depending species. The drier active season saw a decrease abundance for Agapostemon virescens Ceratina calcarata , whereas Bombus impatiens Xenoglossa pruinosa increased when compared previous year. Wetter seasons resulted smaller body sizes greater wear all examined. For larger bees ( A. B. X. ), increasing significantly females only foraging effort reduced intensity increased. small, cavity‐nesting bee, C. exhibited urbanization. Moderate better supported most assemblages morphology, suggesting that moderate land use provides green spaces adequate resources

Determining the impact of ecological processes on adaptive genetic variation in wild populations can aid evaluating resilience potential species conservation concern. However, an in-depth understanding gene-environment interactions to uncover patterns global biodiversity losses requires inclusion non-model taxa genomic studies. For insects, this goal be achieved by use pinned specimens from curated collections. In study, we employ infer population structure and test for evidence divergence a native North American bee, Agapostemon virescens. We compare samples across three collections methods (pan trap, sweep net, blue vane) verify utility genetics studies, while at same time providing insights into local adaptation ground-nesting pollinator. Genome-wide single nucleotide polymorphism (SNP, n = 30,829) data revealed that A. virescens eastern Canada is comprised one cluster, with low levels differentiation between regions. Furthermore, each four examined regions had heterozygosity exhibited significant inbreeding. By examining signatures selection associated environmental variation, identified outlier SNPs corresponding genes involved energy metabolism, pathogen response insecticide resistance. Combined, these findings help characterize structure, diversity pollinator enhance our general bees.

Abstract Wild pollinators and their microbiota are sensitive to land use changes from anthropogenic activities that disrupt landscape environmental features. As urbanization agriculture affect bee habitats, human-led disturbances driving in microbiomes, potentially leading dysbiosis detrimental fitness. This study examines the bacterial, fungal, plant compositions of small carpenter bee, Ceratina calcarata, its pollen provisions across an urban–rural divide. We performed metabarcoding C. calcarata Toronto by targeting 16S rRNA, ITS, rbcL regions. Despite similar composition diversity bees provisions, there was a greater microbial than bees. By characterizing differences use, climate, pesticide residues differentiate urban rural landscapes, we find areas support elevated levels more complex networks between microbes plants areas. However, may lead lower relative abundances known beneficial symbionts increased pathogens, such as Ascosphaera Alternaria fungi. Further, indicate dysregulate symbiosis. continue alter ever changing environments threaten crucial maintaining health.
