Gary Powney and Tom Oliver explain how using data from the UK Butterfly Monitoring Scheme they can assess functional connectivity - the permeability of landscapes.

Nicholas Gotelli and Fernando T. Maestre discuss simple randomization tests for quantifying the effect of species on ecosystem variables, and the use of "natural experiments" to explore their contribution to ecosystem function.

Shannon Pelini demonstrates experimental equipment designed to test the effects of warmer climates on forest ecosystems - and, particuarly, arthropods.

Brett Favaro, Simon Fraser University and Vancouver Island University, demonstrates the construction of TrapCam apparatus: an inexpensive camera system developed for the study of deepwater animals and ecology.

Adam Davis demonstrates how field experiments and statistical models can can enable the extrapolation of long-term seed predation rates from short-term data

On the 9th of March, 2011, Methods in Ecology and Evolution sponsored this symposium with over 200 delegates and 12 speakers, held at the Zoological Society of London meeting rooms

Gurutzeta discusses the impact of partial occupancy on such studies, highlighting the necessity of a careful understanding of a system before deciding whether to sample with replacement

Fraser demonstrates that the Likelihood Ratio Test (LRT) may be applied to non-nested models by comparison of competing models, through comparison of simulated data sets

Shane explains the need for new indices to combine data from many different studies, allowing the creation of composite measures of mean niche overlap, which is of interest to population and community ecologists. Shane also demonstrates the R code developed to achieve this goal

Martin, Alexandru and Dennis discuss the need for a broad spectrum of approaches in understanding the effects of atmospheric carbon dioxide, and demonstrate their innovative experimental equipment at the Ecotron Controlled Environment Facility, Imperial College London, Silwood Park, UK
