Identifying conservation priority areas for North American bumble bee species in Canada under current and future climate scenarios

Conservation Science and Practice, Journal Year: 2023, Volume and Issue: 5(8)

Published: July 5, 2023

Abstract Many bumble bee species are declining globally from multiple threats including climate change. Identifying conservation priority areas with a changing will be important for conserving species. Using systematic planning, we identified 44 in Canada under current and projected climates (year 2050). Conservation were as those that contained targeted amounts of each predicted occurrence through envelope models, while minimizing the area cost areas. two periods compared to established protected land cover types determine future sites landscapes within Notably, rarely Priority most often croplands grasslands, mainly mountain west, central Southern Ontario, Northern Quebec, Atlantic all scenarios. increase elevation latitude Our findings identify regions consistently selected sites.

Pollen associated with a Texas population of blow flies‐(Diptera: Calliphoridae) highlights underappreciated aspects of their biology

Ecological Entomology, Journal Year: 2023, Volume and Issue: 49(2), P. 215 - 224

Published: Nov. 14, 2023

Abstract Over 80% of agricultural crops rely on insect pollination. Thus, pollinator biodiversity is critical for augmented plant yield and quality. Blow flies (Diptera: Calliphoridae) are acknowledged pollinators several crops. However, there many open questions regarding their importance in pollination ecology. For instance, has not been a comprehensive assessment pollen use by blow flies, thus, it unknown whether individuals visit few or types per trip. At least one fly species ( Lucilia sericata ) can digest the protein therein as an oogenic resource. this commonly used strategy acquisition, given that they more associated with faeces, carrion myiasis. We surveyed found guts to determine (a) consume pollen, if so, which pollen; (b) exhibit species‐specific (c) demonstrate sex‐specific use. collected from natural habitats around Central Texas 2016 2019 dissected look presence pollen. widespread variety plants six discovered bias amount female compared males some, but all species. Pollen represents relatively underappreciated aspect biology, potential ecological impacts ranging disease ecology diversity.

Synergistic effects of multiple pesticides on the flight ability of honey bees (Apis ceranaF.)

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2023, Volume and Issue: unknown

Published: May 24, 2023

Abstract Pesticides cause risks in the environment for Asian honey bees ( Apis cerana ). Imidacloprid (I), chlorpyrifos (C) and glyphosate (G) are among most-widely used pesticides world. It is not clear on how these combination of them affect flight ability A. . Here we utilized mills to show new results that acute treatment individual pesticides, such as 0.2 ng/bees imidacloprid (20 μL, 10 ng/g), 0.6 30 ng/g) 1.2 60 had no effect bees. However, forager showed a significantly decrease flying duration distance when oral exposed two or three pesticides. This evidence indicated can produce synergistic changes behavior honeybees.

A Spatially Explicit Model of Landscape Pesticide Exposure to Bees: Development, Exploration, and Evaluation

Published: Jan. 1, 2023

Pesticides represent one of the greatest threats to bees and other beneficial insects in agricultural landscapes. Potential exposure is generated through compound- crop-specific patterns pesticide use over space time unique degradation behavior among compounds. Exposure develops from this template established by loading bee foraging movement their nests across spatiotemporal mosaic floral resources throughout landscape. Despite recognized importance a landscape-wide approach assessing exposure, we lack predictive framework inform mitigation decisions environmental risk assessment for bees. We address gap developing model that incorporates patterns, estimated rates degradation, resource dynamics habitats, movements. parameterized with data public database containing crop-field- date-specific records uses our study region an entire year. evaluate performance predicting using dataset residues pollens gathered bumble (Bombus vosnesenskii) returning 28 colonies 14 spatially independent landscapes Northern California. applied alternative formulations accumulation seasonality, explore different levels detail observed exposure.
