“…An example of one of these particularly influential species is Hieracium pilosella, a plant native to central Europe and locally rare in our study sites. This species was positively associated with multifunctionality according to our method and has previously been shown to increase soil organic carbon, litter decomposition and microbial biomass in comparison to other grassland species [62], to attract a variety of pollinators [63] and to have a relatively high resistance to pathogenic fungal infections [64]. We found a similar number of influential species for both common and rare species, and for both above-and below-ground organisms; indicating that individual species within these biotic components are equally important for multifunctionality.…”

One contribution of 17 to a theme issue 'Biodiversity and ecosystem functioning in dynamic landscapes'. Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, the relative functional importance of rare and common species in driving the biodiversity-multifunctionality relationship remains unknown. We studied the relationship between the diversity of rare and common species (according to their local abundances and across nine different trophic groups), and multifunctionality indices derived from 14 ecosystem functions on 150 grasslands across a landuse intensity (LUI) gradient. The diversity of above-and below-ground rare species had opposite effects, with rare above-ground species being associated with high levels of multifunctionality, probably because their effects on different functions did not trade off against each other. Conversely, common species were only related to average, not high, levels of multifunctionality, and their functional effects declined with LUI. Apart from the communitylevel effects of diversity, we found significant positive associations between the abundance of individual species and multifunctionality in 6% of the species tested. Speciesspecific functional effects were best predicted by their response to LUI: species that declined in abundance with land use intensification were those associated with higher levels of multifunctionality. Our results highlight the importance of rare species for ecosystem multifunctionality and help guiding future conservation priorities.

“…Native to Europe, western Asia and northern Africa, A. manicatum is a solitary species that has been accidentally introduced to South America, the USA, Canada, the Canary Islands, Siberia and New Zealand (Proshchalykin 2007;Gibbs & Sheffield 2009). It was first discovered in Napier and Nelson in 2006 (Donovan 2007), adding to New Zealand's comparatively small bee fauna of 40 species, most of which are endemic (Donovan 2007;Howlett & Donovan 2010). In New Zealand, other insect pollinators such as moths, flies and beetles, as well as birds, play an important role in pollination (Newstrom & Robertson 2005; Kelly et al 2006, 2010).…”

Introduced pollinator species may exacerbate the problems faced by pollinator communities, so the detection in 2006 of a new solitary bee, Anthidium manicatum, to New Zealand was concerning. We assess whether establishment of this wool-carder bee presents potential risks to native flora and fauna by recording its current distribution, which plant species it visits, which insects co-occur at these plants, and identifying which species this territorial bee attacks. Anthidium manicatum is now widespread in urban New Zealand. More than 80% of the plants visited by A. manicatum were exotic species (predominantly Lamiaceae and Plantaginaceae), although it also visited native species of Veronica (Plantaginaceae) and Lobelia (Campanulaceae). Anthidium manicatum primarily interacted with other introduced bees. Native Lasioglossum bees were seldom attacked and only for short durations. Further research is required, particularly on weeds, but we suggest that A. manicatum does not present a major direct threat to New Zealand's native flora and fauna.

“…In Europe, estimated densities of honey bee colonies suggest that managed honey bees significantly supplement wild populations (Jaffé et al 2010). Since the discovery of V. destructor in the North Island of New Zealand and its subsequent spread to the South Island in 2006, feral honey bee populations across the country have declined dramatically (Howlett and Donovan 2010). This loss of feral honey bees may ultimately have more of an impact on pollination services than Varroa infestation of managed hives (Garibaldi et al 2013).…”

“…While resource competition between honey bees and native bees has yet to be identified in New Zealand, there have been very few studies undertaken to evaluate the degree of overlap between honey bees and native bees in this country (Howlett and Donovan (2010). A review of competitive interactions between honey bees and native bees across multiple continents, however, indicates that honey bees can have a negative effect on native bees (Paini 2004), but nowhere in the world has experimental manipulation of pollinator assemblages and resources utilization been conducted before and after V. destructor invasion.…”
