“…More importantly, it has been shown that locomotor activity is positively correlated with the ability to Þnd resources under Þeld conditions (Overgaard et al 2010). In addition to Þeld experiments, comparative studies including multiple populations originating from different habitats or the use of isofemale lines could be used to test the evolutionary signiÞcance of locomotor activity in future studies (Bahrndorff et al 2006(Bahrndorff et al , 2010. Several studies have shown how the activity of vectors can affect disease transmission.…”

The behavior of ectotherm organisms is affected by both abiotic and biotic factors. However, a limited number of studies have investigated the synergistic effects on behavioral traits. This study examined the effect of temperature and density on locomotor activity of Musca domestica (L.). Locomotor activity was measured for both sexes and at four densities (with mixed sexes) during a full light and dark (L:D) cycle at temperatures ranging from 10 to 40ºC. Locomotor activity during daytime increased with temperature at all densities until reaching 30ºC and then decreased. Highdensity treatments significantly reduced the locomotor activity per fly, except at 15ºC. For both sexes, daytime activity also increased with temperature until reaching 30 and 35ºC for males and females, respectively, and thereafter decreased. Furthermore, males showed a significantly higher and more predictable locomotor activity than females. During nighttime, locomotor activity was considerably lower for all treatments. Altogether the results of the current study show that there is a significant interaction of temperature and density on daytime locomotor activity of M. domestica and that houseflies are likely to show significant changes in locomotor activity with change in temperature.

Locomotor activity was measured for both sexes and at four densities (with mixed sexes) during a full light and dark (L:D) cycle at temperatures ranging from 10 to 40ЊC. Locomotor activity during daytime increased with temperature at all densities until reaching 30ЊC and then decreased.

For both sexes, daytime activity also increased with temperature until reaching 30 and 35ЊC for males and females, respectively, and thereafter decreased.

“…At the phenotypic level many studies have shown clinal variation in various resistance traits along climatic gradients (Hoffmann et al 2003;Sørensen et al 2005b;Bahrndorff et al 2006;Sarup et al 2006). However, for some traits clinal variation is only found in some studies, in one gender or life stage or under specifi c environmental conditions (see e.g.…”

“…While annual means in temperatures are usually available and correlate well with latitude, this may have only little effect for the populations. The variation or extreme events during days, seasons and years probably affect populations much more and are thus much more important (Bahrndorff et al 2006). Sarup et al (2006) made a study of climatic adaptation in different life stages of D. buzzatii populations collected in a geographical area where knowledge of many climatic parameters was available.…”

Most investigations on the effects of and responses to stress exposures have been performed on a limited number of model organisms in the laboratory. Here much progress has been made in terms of identifying and describing beneficial and detrimental effects of stress, responses to stress and the mechanisms behind stress tolerance. However, to gain further understanding of which genes are involved in stress resistance and how the responses are regulated from an ecological and evolutionary perspective there is a need to combine studies on multiple levels of biological organization from DNA to phenotypes. Furthermore,we emphasize the importance of studying ecologically relevant traits and natural or semi-natural conditions to verify whether the results obtained are representative of the ecological and evolutionary processes in the field. Here,we will review what we currently know about thermal adaptation and the role of different stress responses to thermal challenges in insects, particularly Drosophila.Furthermore,we address some key questions that require future attention.

“…Springtails are a globally significant group of organisms that play a major role in ecosystem functioning (Rusek 1998). Earlier studies have shown that O. cincta is adapted to local conditions including temperature (Timmermans et al 2005b;Bahrndorff et al 2006), and shows significant variation in temperature-induced plasticity of life history traits (Ellers et al 2008;Liefting and Ellers 2008).…”

Temperature is considered one of the most important mediators of phenotypic plasticity in ectotherms. However, the costs and benefits shaping the evolution of different thermal responses are poorly elucidated. One of the possible constraints to phenotypic plasticity is its intrinsic genetic cost, such as genetic linkage or pleiotropy. Genetic coupling of the thermal response curves for different life history traits may significantly affect the evolution of thermal sensitivity in thermally fluctuating environments. We used the collembolan Orchesella cincta to study if there is genetic variation in temperature-induced phenotypic plasticity in life history traits, and if the degree of temperature-induced plasticity is correlated across traits. Egg development rate, juvenile growth rate and egg size of 19 inbred isofemale lines were measured at two temperatures. Our results show that temperature was a highly significant factor for all three traits. Egg development rate and juvenile growth rate increased with increasing temperature, while egg size decreased. Line by temperature interaction was significant for all traits tested; indicating that genetic variation for temperature-induced plasticity existed. The degree of plasticity was significantly positively correlated between egg development rate and growth rate, but plasticity in egg size was not correlated to the other two plasticity traits. The findings suggest that the thermal plasticities of egg development rate and growth rate are partly under the control of the same genes or genetic regions. Hence, evolution of the thermal plasticity of traits cannot be understood in isolation of the response of other traits. If traits have similar and additive effects on fitness, genetic coupling between these traits may well facilitate the evolution of optimal phenotypes. However, for this we need to know the selective forces under field conditions.
