Issue 2.5 of Methods in Ecology and Evolution is published today, and it’s a special 150 page bumper edition!
The tempo of evolution heads the bill for this issue, with a strong phylogenetic duo in Measuring the temporal structure in serially sampled phylogenies by Rebecca R. Gray, Oliver G. Pybus and Marco Salemi, and A simple polytomy resolver for dated phylogenies by Tyler S. Kuhn, Arne Ø. Mooers and Gavin H. Thomas. The nature of life-history evolution is also examined, with a re-interpretation of the ubiquity of post-reproductive lifespan in Levitis and Lackey’s A measure for describing and comparing postreproductive life span as a population trait.
Two papers describe improved camera trapping methods, leading towards a practical application of the random encounter model in Quantifying the sensitivity of camera traps: an adapted distance sampling approach (Rowcliffe et al.), and towards a measure for correcting for observer error in Estimating survival in photographic capture–recapture studies: overcoming misidentification error (Morrison et al.).
An innovative use of stable isotope analysis to the problem of tracking carnivore ranges is explored in Tracking large carnivore dispersal using isotopic clues in claws: an application to cougars across the Great Plains by Hénaux et al., while an inexpensive, convenient and widely applicable assay for comparitive analysis of avian immune function is introduced in A simple assay for measurement of ovotransferrin – a marker of inflammation and infection in birds by Horrocks et al. An improved method for raising honeybees in vitro, with potential to improve urgent research on colony collapse disorder, is proposed by Hendriksma et al. in Honey bee risk assessment: new approaches for in vitro larvae rearing and data analyses.
Three papers deal with predicting and modelling range expansions, invasive migrations, and community upheaval under climate change. Improving prediction and management of range expansions by combining analytical and individual-based modelling approaches, by Travis et al., and A benefit analysis of screening for invasive species – base-rate uncertainty and the value of information, by Sahlin et al., provide useful tools for improved modelling under these uncertain conditions, while by contrast Heating up the forest: open-top chamber warming manipulation of arthropod communities at Harvard and Duke Forests, by Pelini et al., showcases an ingenious experimental setup for artificially simulating global change on a small scale, and in situ.
Population structure and community connectivity are addressed in Powney et al.’s Measuring functional connectivity using long-term monitoring data, and Joppa & Williams’ The influence of single elements on nested community structure.
Two papers on population modelling round off the issue, with Transient sensitivity analysis for nonlinear population models by Taverner et al., and Estimating abundance from presence/absence maps by Wen-Han Hwang and Fangliang He.
