New ALMaSS collaborators from Portugal
Welcome to Sonia, Alberto, Antonio and Joana, from Braganca and Coimbra in Portugal!
Sonia and Alberto are part of a new project to extend the ALMaSS system to model Portuguese landscapes, and in particular olive growing regions. New additions to the ALMaSS species will be needed here, starting with a Collembola model. Once properly underway a short description of the project and its progress will be available on the discussion forum.
Antonio and Joana are both from Coimbra... (see more)
ALMaSS paper on recovery
"Recovery based on plot experiments is a poor predictor of landscape-level population impacts of agricultural pesticides"
Environmental Toxicology Chemistry 2014;33:1499–1507.
Current European Union regulatory risk assessment allows application of pesticides provided that recovery of nontarget arthropods in-crop occurs within a year. Despite the long-established theory of source-sink dynamics, risk assessment ignores depletion of surrounding populations... (see more)
Goose threads moved to Goose Modelling
I have moved the goose threads under a new discussion group called goose modelling. We can more easily discuss new matters in new threads in that group.
Landscape structure mediates the effects of a stressor on field vole populations - new paper
A new ALMaSS paper has been published, currently online first in the journal Landscape Ecology. DOI 10.1007/s10980-013-9932-7 link
There is a pdf deposited in the pdf library. This is an important piece of work demonstrating how landscape strucuture can effect the results of pesticide risk assessments for small mammals.
Abstract: Spatio-temporal landscape heterogeneity has rarely... (see more)
