Insect Pollinator Voucher Collection: Pollinator Visitation to Pacific Northwest Native Plants and Native Cultivars

Wed, 18 Dec 2024 00:00:00 -0800

Planting native flora continues to grow in popularity as a means of conserving pollinator fauna in fragmented landscapes. Due to the limited availability of native plants, consumers may encounter cultivars in their search for plants native to their region. Though consumers have a documented interest in planting native flora for their purported benefits to pollinators, it is unclear whether cultivars provide the same benefits as wild-type native plants. Over three years (2020-2022), we observed and collected pollinators from a common garden experiment in Corvallis, OR containing 8 species of Pacific Northwest native plants, 18 cultivars derived from native plant species, and one exotic perennial plant. Methods for collection are described in further detail in Hayes et al. (in prep.). Here, we report on and document the deposition of taxonomic voucher specimens which represent the primary species concepts used throughout Hayes et al. (in prep.) (Accession #). Specimens were identified to the lowest possible taxonomic level by L. R. Best (bees, Hymenoptera: Apoidea) and J. J-M. Hayes (syrphid flies, Diptera: Syrphidae). The vouchered material includes 139 individual specimens with at least one representative per caste and sex, as available, of 55 species and 14 morphospecies of bees (Hymenoptera: Apoidea) and 13 species and one morphospecies of syrphid flies (Diptera: Syrphidae). Additional vouchers are included for specimens identified only to the morphospecies level, and Megachile brevis Say, 1837 individuals that were captured while collecting sections of petal from Clarkia amoena (Lehm.) A.Nelson & J.F.Macbr. plants. These 139 voucher specimens come from a much larger dataset, containing over 6,500 observational records of plant-pollinator interactions.

Occurrence records and taxonomic voucher specimens for study of wild bee communities in early seral forests generated by wildfire, post-fire salvage logging, and intensive forest management in southwest Oregon

Early seral forests regenerating after stand-replacing disturbance events can provide important habitat for populations of wild bees, an important group of pollinating insects. However, variability in the abundance and diversity of wild bee communities across different types of early seral forests is poorly understood, and can inform pollinator conservation efforts and sustainable forest management practices. In this study, we compared wild bee assemblages from early seral forests regenerating from three widespread stand-replacing disturbances across a gradient in stand ages in the Klamath Ecoregion of southwest Oregon using blue vane traps. Here, we present occurrence data for each bee specimen observed in the study, including voucher specimens deposited to the Oregon State Arthropod Collection
