Predicting performance and survival across topographically heterogeneous landscapes: the global pest insect Helicoverpa armigera (Hübner, 1808) (Lepidoptera: Noctuidae)
(Australian Entomological Society, 2014)
Species distribution models provide a means of better understanding how climate constrains the survival of organisms. Although effective in predicting the presence or absence of species across the landscape, model outputs ...
Evolved variation in cold tolerance among populations of Eldana saccharina (Lepidoptera: Pyralidae) in South Africa
(European Society for Evolutionary Biology, 2014)
Among-population variation in chill-coma onset temperature (CTmin) is thought to reflect natural selection for local microclimatic conditions. However, few studies have investigated the evolutionary importance of cold ...
Impacts of environmental variability on desiccation rate, plastic responses and population dynamics of Glossina pallidipes
(European Society for Evolutionary Biology, 2014-02)
Physiological responses to transient conditions may result in costly responses with little fitness benefits, and therefore, a trade-off must exist between the speed of response and the duration of exposure to new conditions. ...
Investigating population differentiation in a major African agricultural pest: evidence from geometic morphometrics and connectivity suggests high invasion potential
(John Wiley & Sons Ltd, 2016)
The distribution, spatial pattern and population dynamics of a species can be influenced by differences in the environment across its range. Spatial variation in climatic conditions can cause local populations to undergo ...
Thermal biology, population fluctuations and implications of temperature extremes for the management of two globally significant insect pests
The link between environmental temperature, physiological processes and population fluctuations is a significant aspect of insect pest management. Here, we explore how thermal biology affects the population abundance of ...
