“…Most studies use cooling rates between 0.1 and 0.25 °C/min for determining CT min (e.g. Kleynhans et al, 2014;MacMillan and Sinclair, 2011b;Terblanche et al, 2006). Note that there has been considerable recent debate on the 'correct' rate for measuring high temperature tolerances Santos et al, 2011;Terblanche et al, 2007;Terblanche et al, 2011), and it is therefore imperative to clearly report the conditions when describing CT min experiments.…”

Insect performance is limited by the temperature of the environment, and in temperate, polar, and alpine regions, the majority of insects must face the challenge of exposure to low temperatures. The physiological response to cold exposure shapes the ability of insects to survive and thrive in these environments, and can be measured, without great technical difficulty, for both basic and applied research. For example, understanding insect cold tolerance allows us to predict the establishment and spread of insect pests and biological control agents. Additionally, the discipline provides the tools for drawing physiological comparisons among groups in wider studies that may not be focused primarily on the ability of insects to survive the cold. Thus, the study of insect cold tolerance is of a broad interest, and several reviews have addressed the theories and advances in the field. Here, however, we aim to clarify and provide rationale for common practices used to study cold tolerance, as a starter's guide for newcomers to the field, students, and those wishing to incorporate cold tolerance into a broader study. We cover the 'tried and true' measures of insect cold tolerance, the equipment necessary for these measurement, and summarize the ecological and biological significance of each. Additionally, we provide a suggested framework and workflow for measuring cold tolerance and low temperature performance in insects.

“…Forecasts of the effects of climate change have focused on the way in which species' ranges will be altered and how extinction is affected by rapid change and habitat loss ( Thomas et al 2004). The human health consequences of changes in vector distributions have been an especially significant and controversial component of these forecasts (Rogers & Randolph 2000;Terblanche et al 2006). Much of the modelling work is based on habitat models that seek to understand the present correlations among environmental factors and species abundances or distributions.…”

Macrophysiology for a changing world

The Millennium Ecosystem Assessment (MA) has identified climate change, habitat destruction, invasive species, overexploitation and pollution as the major drivers of biodiversity loss and sources of concern for human well-being. Understanding how these drivers operate and interact and how they might be mitigated are among the most pressing questions facing humanity. Here, we show how macrophysiology-the investigation of variation in physiological traits over large geographical, temporal and phylogenetic scalescan contribute significantly to answering these questions. We do so by demonstrating, for each of the MA drivers, how a macrophysiological approach can or has helped elucidate the impacts of these drivers and their interactions. Moreover, we illustrate that a large-scale physiological perspective can provide insights into previously unrecognized threats to diversity, such as the erosion of physiological variation and stress tolerance, which are a consequence of the removal of large species and individuals from the biosphere. In so doing we demonstrate that environmental physiologists have much to offer the scientific quest to resolve major environmental problems.

“…Such changes have been convincingly documented for butterflies in Britain, Australia, and North America (Dennis & Hardy, 1999;Hill et al, 1999;Beaumont & Hughes, 2002;Oberhauser & Peterson, 2003;Crozier & Dwyer, 2006), ground beetles (Eyre et al, 2004), cicadas species (Robertson et al, 2004), tsetse flies (Terblanche et al, 2006), and ticks (Wilkinson, 1967;Lindgren et al, 2000;Estrada-Pena, 2002). Analyses of how agricultural pest insects will respond to climate change are surprisingly rare (but see Coviella & Trumble, 1999;McKenney et al, 2003;Gevrey & Worner, 2006).…”

Climate change may dramatically affect the distribution and abundance of organisms. With the world's population size expected to increase significantly during the next 100 years, we need to know how climate change might impact our food production systems. In particular, we need estimates of how future climate might alter the distribution of agricultural pests. We used the climate projections from two general circulation models (GCMs) of global climate, the Canadian Centre for Climate Modelling and Analysis GCM (CGCM2) and the Hadley Centre model (HadCM3), for the A2 and B2 scenarios from the Special Report on Emissions Scenarios in conjunction with a previously published bioclimatic envelope model (BEM) to predict the potential changes in distribution and abundance of the swede midge, Contarinia nasturtii, in North America. The BEM in conjunction with either GCM predicted that C. nasturtii would spread from its current initial invasion in southern Ontario and northwestern New York State into the Canadian prairies, northern Canada, and midwestern United States, but the magnitude of risk depended strongly on the GCM and the scenario used. When the CGCM2 projections were used, the BEM predicted an extensive shift in the location of the midges' climatic envelope through most of Ontario, Quebec, and the maritime and prairie provinces by the 2080s. In the United States, C. nasturtii was predicted to spread to all the Great Lake states, into midwestern states as far south as Colorado, and west into Washington State. When the HadCM3 was applied, southern Ontario, Saskatchewan, and Washington State were not as favourable for C. nasturtii by the 2080s. Indeed, when used with the HadCM3 climate projections, the BEM predicted the virtual disappearance of 'very favourable' regions for C. nasturtii. The CGCM2 projections generally caused the BEM to predict a small increase in the mean number of midge generations throughout the course of the century, whereas, the HadCM3 projections resulted in roughly the same mean number of generations but decreased variance. Predictions of the likely potential of C. nasturtii spatial spread are thus strongly dependent on the source of climate projections. This study illustrates the importance of using multiple GCMs in combination with multiple scenarios when studying the potential for spatial spread of an organism in response to climate change.
