Can pollinators choose between pesticide-laced and pesticide-free foods? And is choice a good thing in terms of conservation? Paola Olaya‐Arenas and Ian Kaplan discuss their new research. Continue reading Milkweed pesticide residues deter feeding and egg-laying by monarch butterflies
Exploring local and landscape management actions, Costanza Geppert and colleagues recognise the value of flower strips but also point to the importance of organic agriculture when it comes to maintaining pollinator richness. Their new insights were recently published in Journal of Applied Ecology. In recent years, the ‘insect Armageddon’ has received growing attention in Europe. The main driver of this insect decline is agricultural intensification, … Continue reading Flower strips, organic management or small-scale farming: which benefits pollinator abundance, richness and reproduction most?
With demand on shea parklands increasing, Aoife Delaney and colleagues explore the pollination services to shea and how we can better support this resource of both ecological and economic importance. Their new research was recently published in Journal of Applied Ecology. Shea parklands occupy over 1 million km2 in the Sudano-Sahelian semi-arid zone of sub-Saharan Africa, from Senegal in the west to Uganda in the … Continue reading Biodiversity in West African parklands promotes pollination of shea
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
Recent research from Centrella et al. shows the effects agriculture and associated pesticides are having on bees in terms of both their diets and the offspring they produce. Here they discuss their findings. Threats to bee pollinators such as land use change, high pesticide use, and reduced floral diet diversity are usually assessed independently, even though we know that bees face these threats simultaneously in … Continue reading Bee pollen reveals how multiple threats could contribute to bee decline
This month’s Journal of Applied Ecology cover shows a foraging male Habropoda tarsata. Photographer, David Kleijn shares the joy of rediscovering your passion for your study species. These days when we talk and write about pollinators, it is often in the context of their role as providers of pollination services. Pollinators are important for maintaining the production of the insect-pollinated crops that provide most of … Continue reading Cover stories: celebrating the beauty of pollinators
For our March Editor’s Choice, Michael Pocock (Associate Editor) highlights the importance of recent research by Tremlett et al into pollination by bats and the value this brings to communities in Mexico. The slideshow above of images by César Guzmánr shows the journey of the pitaya fruit, for which bats are of key importance, from growth to market. One of the reoccurring themes in applied … Continue reading Editor’s Choice 57:03 – The economic implications of pollination by bats
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
In their recently published article, Tremlett et al. call for greater management focus for wild bat pollinator populations due to the ecosystem services they provide for valuable crops. Here they share a video of bat feeding in action and explain a little more about their work. *Update March 2020. The corresponding article to this video features as the Editor’s Choice for issue 57:03. Read Associate … Continue reading Why bats matter when it comes to pollination
An English version of this post is available here. La mayoría de los esfuerzos para promover la conservación de polinizadores están enfocados en mantener o incrementar el rango de plantas con flores disponibles para ellos. La razón es simple: las plantas con flores proveen néctar y polen, recursos esenciales para su subsistencia. Sin embargo, los polinizadores dependen de otros recursos que probablemente también determinan su … Continue reading Conservando flores conservamos polinizadores?
