Neo was right—The Matrix explains everything

Post provided by Jody Reimer

One of the unifying themes in ecology may be the acknowledgement that we live in a world of finite resources, and so we also live in a world of tradeoffs. A diverse range of research questions can be distilled into a question about tradeoffs. For example, how should an animal forage in the presence of predation? Which selective forces determine the life history of a flowering perennial? How should we manage a population to maximize the sustainable harvest rate?

Questions as varied as these can all be addressed using the same method of stochastic programming[1] (SDP) (see McNamara and Houston, 1986; Rees et al. 1999; and Runge and Johnson, 2002, respectively). SDP has been used extensively to study optimal tradeoffs in a wide range of applications in ecology, evolutionary biology, and management. It is a flexible and powerful modelling framework that allows for simultaneous consideration of an individual’s state, how an optimal decision might explicitly depend on time, and for a probabilistic landscape of risks and rewards.

Latest issue and other articles

Issue 3.4 Our latest issue covers an impressive array of subjects: from metabarcoding (with associated presentation), to population genetics and population monitoring (with video explaining a microphone array system). Modelling and monitoring dispersal also features heavily with four articles, one of which is accompanied by a video for a novel telemetry system to track wild animals. Articles also include topics such as transient dynamics, a review … Continue reading Latest issue and other articles

New MEE article featured in Faculty of 1000

Another of our recent articles, Assessing transferability of ecological models: an underappreciated aspect of statistical validation, by Seth Wenger and Julian Olden, has recently been highlighted on Faculty of 1000. F1000 is a platform providing post-publication peer-review and selecting only the most important articles in biology and medicine.

Methods in the press

Two articles have been recently highlighted in the press. Iain Stott, Dave Hodgson and Stuart Townley, University of Exeter, have developed Popdemo, a new software tool for helping prioritise efforts in species conservation. As well as determining which species need our help, it will also be useful in pest control and sustainable harvesting. The University press release was picked up by a variety of websites, … Continue reading Methods in the press

Issue 3.3

About the issue Issue 3.3 contains an amazing number of extra features: three videos, one podcast and one Powerpoint presentation. The topics in the issue range from DNA barcoding, surveys, measuring diversity, population and movement modelling and includes five free applications. About the cover Recently developed light-weighed tracking devices for positioning through light intensity pattern (‘geolocation’) have begun to greatly improve our knowledge of animal … Continue reading Issue 3.3

Recent content and new video

Lots of exciting content has recently gone online. Firstly, two interesting new applications (as always free): simapse, simulation maps for ecological niche modelling in Python and nadiv, an R package for estimating non-additive genetic variances in animal models. Also, two research articles. In the first, Julien Beguin and colleagues introduce an alternative procedure for fitting Bayesian hierarchical spatial models (BHSM) with quite general spatial covariance … Continue reading Recent content and new video
