Adjacent crop type impacts potential pollinator communities and their pollination services in remnants of natural vegetation.

Aim: Pollination plays a crucial role in the conservation of many plant species persisting in fragmented, human-dominated landscapes. Pollinators are known to be instrumental in maintaining genetic diversity and metapopulation dynamics for many plant species and are important for providing ecological services that are essential in agricultural landscapes where populations of native plants are highly isolated. Numerous studies have explored the value of remnant native vegetation for supporting pollination services to crop species; yet the effect of mass-flowering crops on the pollinator communities and the pollination services they provide to native plant communities persisting in fragmented landscapes are less well-understood. Here, we assess the influence of the presence and phenology of a mass-flowering crop to pollinator community structure, abundance and pollen load composition in remnant vegetation in complex agricultural landscapes. Location: South-west Western Australia, Austral...研究目的：传粉作用对于存续于受人类活动主导的破碎化景观中的众多植物物种的保护至关重要。传粉者被证实对维持多数植物物种的遗传多样性与集合种群动态具有关键作用，同时在本土植物种群高度隔离的农业景观中，其提供的生态系统服务亦不可或缺。已有大量研究探讨了残存本土植被为作物提供传粉服务的价值，但大面积开花作物对传粉者群落的影响，及其为破碎化景观中存续的本土植物群落所提供的传粉服务，目前仍鲜为人知。本研究旨在评估大面积开花作物的存在及其物候期，对复杂农业景观内残存植被中的传粉者群落结构、种群丰度及花粉负载组成的影响。研究区域：澳大利亚西澳西南部，澳大利亚……
