Expansion Load and the Evolutionary Dynamics of a Species Range [PDF]
The American Naturalist, 2015 Expanding populations incur a mutation burden, the so-called expansion load. Using a mixture of individual-based simulations and analytical modeling, we study the expansion load process in models where population growth depends on the population's fitness (i.e., hard selection).

Range-Expansion in Processionary Moths and Biological Control [PDF]
Insects, 2020 Global climate change is resulting in a wide range of biotic responses, including changes in diel activity and seasonal phenology patterns, range shifts polewards in each hemisphere and/or to higher elevations, and altered intensity and frequency of ...

Impacts of climate driven range changes on the genetics and morphology of butterflies [PDF]
, 2011 This thesis studied the genetic responses of butterflies to climate induced distribution shifts in terms of patterns of genetic diversity at expanding and contracting range margins, the relative importance of genes versus environment on adaptations to ...

An advanced decision process for capacity expansion in manufacturing networks [PDF]
, 2008 Manufacturing companies develop multiple production sites for various reasons from cheaper labour to access to local markets. Expansion of capacity in such a manufacturing network is a complex decision and requires consideration of multiple factors ...

Range Expansion of Heterogeneous Populations [PDF]
Physical Review Letters, 2014 Risk spreading in bacterial populations is generally regarded as a strategy to maximize survival. Here, we study its role during range expansion of a genetically diverse population where growth and motility are two alternative traits. We find that during the initial expansion phase fast growing cells do have a selective advantage.

Linking habitat use to range expansion rates in fragmented landscapes: a metapopulation approach [PDF]
, 2010 Temperature increases because of climate change are expected to cause expansions at the high latitude margins of species distributions, but, in practice, fragmented landscapes act as barriers to colonization for most species.

Fauna Norvegica, 2020 A small (36.5 cm) female walleye pollock Gadus chalcogrammus Pallas, 1814 was caught north of Spitsbergen in 2011. The specimen had a high number of pyloric caeca (n=109), indicating a Pacific origin.

Ecology and Evolution, 2021 It is prevalent to use ecological niche models in the analysis of species expansion and niche changes. However, it is difficult to estimate the niche when alien species fail to establish in exotic areas.

Testing consistency of modelled predictions of the impact of climate change on bats
Climate Change Ecology, 2021 Species Distribution Models (SDMs) are a cornerstone of climate change conservation research but temporal extrapolations into future climate scenarios cannot be verified until later this century.

Expansion of the Range of Pierce's Disease in Virginia [PDF]
Plant Health Progress, 2007 Pierce's disease (PD) is a vascular disease of grapes vectored by xylem-feeding sharpshooters and leading to vine decline, yield loss, and vine death. Recent warm winters have increased concerns about PD in Virginia. The authors conducted a survey of 31 Virginia vineyards in 21 counties for X. fastidiosa in late fall, 2006.
