7 June 2021: Our new paper has just come out on social norms as a tool to promote pro-environmental behaviour. Check it out here.
3 June 2021: Our paper has just come online open at Conservation Letters. It's a perspective drawing attention to the inequity (even hypocrisy?) associated with calls to ban wild meat in response to covid. These measures disproportionately impact Indigenous Peoples and those in poverty, while ignoring other important causes of zoonosis (farming, habitat loss) that benefit wealthier consumers. In other words, it shifts the burden of pandemic prevention to a subset of humanity. Check it out here.
25 May 2021: Carla's paper has just come out as online early in Biological Reviews. It uses a national-scale meta-analysis to explore how land use influences trade-offs among a suite of ecosystem services. It also demonstrates that the strongest trade-offs occur when comparing native/natural with exotic/production systems, whereas differences between forested vs. unforested were less significant. Check it out here.

Check it out here.
7 May 2019: Our new paper, led by David Orme and Cris Banks-Leite, just came out in Nature Ecology and Evolution. It shows that species' sensitivity to habitat fragmentation is greatest in populations near their range edge. This suggests that species-level characteristics (e.g. traits) are not likely to be a good indicator of vulnerability to drivers such as fragmentation, unless they are considered within the context of other environmental drivers that determine the boundaries of species' geographic range. Check it out here (paywalled) or free read-only version here.

4 May 2018: Congratulations Sophie on submitting your masters thesis!
4 April 2018: Our new paper has just come online early at Ecology Letters (see it here). It shows that species that have few degrees of separation (i.e. short path lengths) from others are better able to attract interaction partners during community assembly, and also more likely to retain them during disassembly. These symmetrical assembly and disassembly processes are capable of producing important network structures such as nestedness. Our finding that short path lengths to all other species was more important than the number of direct interaction partners suggests that indirect effects may be important for network assembly and disassembly processes.

16 Nov 2016: Lupe's new paper is now online early at Ecology (read it here). In earlier work we found that food-web structure can differ systematically across habitats, but this raises the question of how food webs merge at the interface of two habitats. This paper uses empirical parasitoid-host networks from native and plantation forest edges to show that the edge web is not a mere blending of the webs from the two adjacent habitats. Rather, increases in generalist parasitoids at edges generated more highly-connected networks.
14 Oct 2016: Sophie has officially begun her masters in our group - welcome aboard Sophie!
4 Oct 2016: Welcome to our two new postdocs, Johanna and Warwick!
31 August 2016: Our new paper led by Carol Frost has just come out in Nature Communications (read it here). It shows that attack rates on hosts, and their consequent changes in population size, can be predicted by their sharing of natural enemies (parasitoids) with other hosts in the food web. Moreover, it shows that this apparent competition occurs across different habitats, such that the entire landscape functions as a single meta-network.
