They shoot horses, don’t they?
Ok, that’s just a provocative way of introducing an interesting review in Trends in Ecology and Evolution describing how harvesting from animal populations can affect their genetic make-up. 1 The following three types of genetic change are highlighted:
- strengthening or collapse of population structure
- genetic erosion
- selection
The take-home message is that management plans should recognize that harvesting changes not just the demography but also the genetics of populations. Very important for sustainable management of fisheries etc., but I bring it up here because it got me thinking: are any wild relatives of livestock exploited through harvesting? Things like these cute pigs, for example. And would the conclusions be very different for plants?

Pollinator diversity, pollination services and landscape change
That’s the title (or part of it) of a guest editorial 2 in the latest issue of the Journal of Applied Ecology which introduces a Special Profile entitled “Pollination and Pollinators” (mainly bees, actually).
The papers in this Special Profile cover several of these topics: two papers address the impact of habitat fragmentation and semi-natural landscape elements for population densities, species richness and community composition of bees (Brosi et al. 2008; Osborne et al. 2008). The next three papers focus on the combined effects of local and landscape-scale land use intensity and semi-natural or natural landscape elements on pollinators (Kohler et al. 2008; Rundlöf, Bengtsson & Smith 2008; Winfree et al. 2008). The last two papers focus on pollination functions and consider cross-pollination rates in a major crop (Devaux et al. 2008) and plant–pollinator networks in heathlands (Forup et al. 2008).
The papers are behind paywalls, but the abstracts are still quite useful.
I guess the overall message is that “land use intensification and habitat fragmentation do not only affect pollinator diversity and abundance, but also pollination services” because “pollination success of insect-pollinated plant species is usually not dependent on single, highly specialized pollinator species, but rather on a diverse community of pollinators.” In some places, of course, bees have lots more to contend with.
