Invasive species spaghetti for dinner? A network of species interactions for managing invasive cats and rats on Christmas Island

Invasive cats and rats threaten native species on Christmas Island through predation and indirect changes in ecosystem processes. Management programs have been proposed to eradicate cats and possibly rats. Before an eradication program can commence, however we need to answer a number of key questions. What is the management goal? What are the alternative management strategies? What are the risks and benefits of these management strategies?

Oikos Editor’s Choice September

Oikos Blog

DriesFor the September issues, we chose the forum paper of Caplat et al. as editor’s choice. The paper arose from a special symposium at the 2011 ESA meeting in Austin, and synthesizes how insights from invasion ecology can help us understanding species responses to climate change. The paper does not aim to provide a systematic review or meta-analysis of the literature, but instead focusses on the useful concepts and insights generated from invasion processes relevant to climate change ecology of plants. The authors particularly focus on processes related to movement and especially the settlement phase and the expected impacts of altered species distributions on recipient ecosystems. While Oikos does not have a special focus on applied ecological research, we do stimulate the translation of fundamental insights into a global change or societal context. This appears especially important in the context of species management, both with respect to conservation and…

New Oikos article about plant movement & invasions

Yvonne and Paul Caplat et al. published a Forum paper on Oikos on the “Movement, impacts and management of plant distributions in response to climate change: insights from invasions” to synthesis the discussion of the ESA-meeting 2011.

A brief summary of the paper can be found on the Oikos journal blog:

2013 Winter School Seminar, University of Queensland

Yvonne recently gave a talk at the 2013 Winter School in Mathematical and Computational Biology at the University of Queensland (1-5 July) on “Management of invasive species, pests and diseases: making decisions in an uncertain and complex world”.

Claire goes to Western Australia again

Our associate PhD student, Claire Wainwright, is out in the York Gum woodland of Western Australia again. On this 6-month field trip, Claire is going to collect empirical data to investigate the processes that drive coexistence of native and exotic annuals in the woodland understorey. Since 2012 was drier than 2013, it would be interesting to compare the temporal difference between two years’ data.

This will be her final field trip in her PhD voyage. All the best Claire!
