Critical thermal limits depend on methodological context
(The Royal Society, 2007-09-18)
A full-factorial study of the effects of rates of temperature change and start temperatures was undertaken for both upper and lower critical thermal limits (CTLs) using the tsetse fly, Glossina pallidipes. Results show ...
Variation in scorpion metabolic rate and rate–temperature relationships: implications for the fundamental equation of the metabolic theory of ecology
The fundamental equation of the metabolic theory of ecology (MTE) indicates that most of the variation in metabolic rate are a consequence of variation in organismal size and environmental temperature. Although evolution ...
Conservation with Caveats
Physiological tolerances account for range limits and abundance structure in an invasive slug.
(The Royal Society, 2009)
Despite the importance of understanding the mechanisms underlying range limits and abundance structure, few studies have sought to do so. Here we use a terrestrial slug species, Deroceras panormitanum, that has invaded ...
Phenotypic plasticity mediates climate change responses among invasive and indigenous arthropods
(The Royal Society, 2007)
Synergies between global change and biological invasion have been identified as a major potential threat to global biodiversity and human welfare. The global change-type drought characteristic of many temperate terrestrial ...
Assemblage level variation in springtail lower lethal temperature: the role of invasive species on sub-Antarctic Marion Island
(The Royal Entomological Society, 2009)
It is widely held both in the physiological literature, and more generally, that the average characteristics of species within an assemblage differ among sites. Such generalizations should be based on investigations of ...
Searching for generality in the patterns of parasite abundance and distribution: Ectoparasites of a South African rodent, Rhabdomys pumilio
(Australian Society for Parasitology Inc. Published by Elsevier Ltd, 2009)
We studied abundance and distribution of seven ectoparasite species (fleas Chiastopsylla rossi and Dynopsyllus ellobius, a louse Polyplax arvicanthis, mites Androlaelaps fahrenholzi and Laelaps giganteus and two ticks ...
The acute hypoxic ventilatory response: Testing the adaptive significance in human populations
(Elsevier Inc, 2005)
The acute Hypoxic Ventilatory Response (HVR) is an important component of human hypoxia tolerance, hence presumably physiological adaptation to high altitude. We measured the isocapnic HVR (L min¯¹ %¯¹) in two genetically ...
An operational model for mainstreaming ecosystem services for implementation
(The National Academy of Sciences of the USA, 2008-07-15)
Research on ecosystem services has grown markedly in recent years. However, few studies are embedded in a social process designed to ensure effective management of ecosystem services. Most research has focused only on ...
Overgrazing and bush encroachment by Tarchonanthus camphoratus in a semi-arid savanna
(Blackwell Publishing Ltd, 2008)
