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

Measuring functional connectivity using butterflies

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.

Measuring the importance of species to ecosystems

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

Heating up the forest

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.

Studying deepwater animals with TrapCam

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

Estimating seed predation rates

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

Integrating ecology into macroevolutionary research

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

The impact of sampling 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

Modelling tick questing abundance

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

Unified analysis of ecological niche overlap

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

Analogue modelling of the terrestrial carbon cycle

Sara Kross, University of Canterbury, New Zealand, shows her fieldsite in New Zealand and a new, portable low-cost remote videography system for monitoring wildlife, developed with Ximena Nelson

Remote monitoring of nesting falcons

Arnaud Tarroux talks to Graziella Iossa about his work on the sensitivity of stable isotope mixing models to variation in isotopic ratios

Lipid extraction and stable isotope ratios

Aaron Ellison talks to Graziella Iossa from his field site in the middle of the Harvard Forest Hemlock Removal site

Foundation species in hemlock forests

Douglas Barron talks to Graziella Iossa about his work in developing a meta-analysis of transmitter effects on avian behaviour and ecology

Radio transmitters and bird ecology

Corey Bradshaw talks to Graziella Iossa about the development of spreadsheet models to aid in reducing invasive animal density

Managing invasive species with spreadsheet modelling

Methods in Ecology and Evolution's video podcast aims to expand the awareness, accessibility and uptake of new metholodologies in ecology and evolution
