New paper: feral honey bees and competition for natural cavities

Manu Saunders2 Comments

Our new paper is out in Frontiers in Ecology and the Environment (open access). We used a combined search of peer-reviewed literature and iNaturalist observations to determine what evidence is available on the use of natural cavities and hollows by feral (wild) western honey bees (Apis mellifera). Our paper addresses an important knowledge gap on how invasive honey bees compete with native species in their introduced range.

The western honey bee (A. mellifera) is one of the world’s most successful invasive species. It has spread far and wide beyond its home range in Europe and the Middle East, and is found on every continent (and most islands) except Antarctica.

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 buzz-pollinate flowers with poricidal anthers and their ease of husbandry has led to the domestication of several species as managed pollinators, particularly Bombus terrestris, a native to Europe.  In many countries, bumblebee colonies are now mass-produced to pollinate a range of different crops in greenhouses, polytunnels and open fields, with an estimatedannual value of €55 million. The recent Policy Direction by Aizen et al.  investigates the consequences of this rapid expansion by reviewing the current…

Workshopping invasive insects

Manu Saunders3 Comments

Last week I was delighted to attend a workshop at Monash University focused on using EICAT methods to assess environmental impacts of invasive insect species. Thank you to Melodie McGeoch and her team (Dave, Chris & Rebecca), and Andrew and Carol from the Invasive Species Council, for inviting me in the first place, and for organising an excellent, productive week. We were also very lucky to have Sabrina Kumschick and Helen Roy there to share their expertise in developing and using EICAT.

It was a ‘proper’ workshop, i.e. a small group of researchers working on a project together with planned outcomes, rather than a training or upskilling ‘workshop’ (why aren’t they just called courses?!). As an early career researcher, it was so rewarding to be there. Research workshops have similar benefits to conferences, in that you have the opportunity to discuss new ideas and network outside your normal collaborative groups. But I find workshops much more fulfilling than conferences, because you have more time to develop those ideas, learn new perspectives, and really get to know people you may not otherwise cross paths with.
