A new study by Timberlake and colleagues finds that late summer nectar supply on farmland has an important influence on bumblebee colony density the following year – does this offer an opportunity to devise more targeted agri-environment schemes for pollinators? Pollen and nectar are the primary food source for most adult pollinators, and in the case of bees, their larvae too. It is no surprise … Continue reading What limits bumblebee populations on farmland?
In their recently published article, Bartomeus et al. show how the commercial bumblebee trade is affecting the genetic integrity of native pollinators. Here the authors provide a summary of their work. Bees, especially bumblebees, are threatened by human-induced rapid environmental change such as habitat loss, exotic pathogens and global warming. But some species are more resilient than others. This is the case for the buff-tailed … Continue reading A new threat to native bumblebees
New research by Néstor Pérez‐Méndez et al. highlights the economic implications of declining pollinator species. Here the authors summarise their work. Recent expansion and intensification of agriculture to meet growing food demands is among the main drivers of the alarming loss of insect diversity worldwide. This decline can lead to a marked degradation of the ecosystem services that insects provide, such as pollination or regulation of crop … Continue reading Loss of bumblebees is a loss to farmers
A new study by Thomas Timberlake et al. reveals seasonal ‘hunger gaps’ in farmland nectar supplies, which could be limiting pollinator populations. But does this offer an opportunity to devise more targeted and cost-effective conservation and agri-environment schemes for pollinators? Nectar and pollen are crucial resources which give bees and other pollinators the energy and protein they need to fly around, reproduce and maintain their … Continue reading Mind the gap: why flower timing matters to farmland pollinators
Addressing pollinator introduction policy and the effects introduced species can have on local ecosystems, Romina Rader, Manu Saunders and Tobias Smith discuss the recent Policy Direction, Coordinated species importation policies are needed to reduce serious invasions globally: The case of alien bumblebees in South America by Aizen et al. Bumblebees (Bombus spp.) are large, iconic pollinators of many wild flowers and crops. Their ability to … Continue reading Bumblebees are frequent flyers – what are the impacts?
