“…In contrast, during active periods, crayfish select warmer temperatures, increasing metabolic energy expenditure, with a trade-off being an increased predation risk as the crayfish that have burrowed congregate with other crayfish in shallower waters. Thus, it appears that the detection and selection of temperature is an important eco-physiological trait in P. clarkii and, presumably, other crayfish (Lagerspetz and Vainio, 2006). In the present study, we demonstrated that P. clarkii learn to thermoregulate behaviourally within a dual-choice shuttlebox.…”

SUMMARYAn unequal resource distribution is commonly seen in dominance hierarchies, in which the individual with the higher status is more successful in obtaining the resource. One possible resource is preferred temperature. When situations allow, ectotherms regulate their body temperature by behaviourally selecting different environmental conditions, achieving, when possible, a preferred temperature. Using a shuttlebox, the preferred temperature for Procambarus clarkii was determined to be 23.9°C with upper and lower voluntary escape temperatures of 25.9 and 21.8°C, respectively. If this preferred temperature zone (21.8-25.9°C) was valued as a resource, given the choice between a preferred temperature and a non-preferred temperature, crayfish should compete over the preferred temperature, with the dominant individual of dyadic pairs achieving the preferred temperature more often than the subordinate. Using a dual-choice experimental tank, competition over a binary temperature choice between rankestablished paired crayfish was determined under both warm and cold challenge conditions (warm vs preferred temperature and cold vs preferred temperature, respectively). In naive pairings, similar levels of competition over the preferred temperature occurred in both warm and cold challenge trials, as predicted by game theory. In established pairings, however, dominant crayfish gained significantly greater access to preferred temperature in both warm and cold challenge conditions. These results demonstrate that crayfish engage in a cost-benefit assessment during their initial agonistic contests over temperature, but as hierarchies mature, these thermal games are decided by the dominant animal gaining primary access to the temperature resource.

“…Temperature selection was observed in many benthic and planktonic crustaceans (Lagerspetz & Vainio, 2006). Usually, it is based on changes in activity and movement speed rather than on a directional taxis (Lagerspetz & Vainio, 2006).…”

“…Temperature may vary vertically due to the stratification of the water column, as well as horizontally and temporally in shallow waters, affected by shading and solar radiation (Lagerspetz & Vainio, 2006). For alien species, temperature can be the most important environmental factor determining the possibility of survival, reproduction and establishment in the new area in the case of climatic differences between the donor and recipient regions (Müller & Baur, 2011).…”

Abiotic factors affecting habitat selection by two invasive gammarids Dikerogammarus villosus and Pontogammarus robustoides

Identification of habitat preferences of invasive organisms is crucial for predicting their distribution and impact. We conducted laboratory experiments to determine preferences of Dikerogammarus villosus and Pontogammarus robustoides, invasive in Europe, with regard to ionic content (450 and 830 lS/cm in a Y-maze), flow (0-30 cm/s in a flow-through tank with stagnant water refuges) and temperature (a gradient 5-35°C). D. villosus selected the lower salinity, whereas P. robustoides did not discriminate between salinities, suggesting that, the raised ionic content in large European rivers cannot explain their absence in small tributaries, as previously postulated. Gammarids never preferred flowing over stagnant water, but could stay in a flow B10 cm/s without behavioural changes. They avoided flow C15 cm/s. Gammarids selected warmer water than their acclimation temperatures. Temperature selection by D. villosus was related to its acclimation temperature. The choice of P. robustoides depended on the season: it preferred a lower temperature in summer than in autumn. Therefore, its thermal preferences were more stable throughout the year, which might be advantageous in shallow, thermally variable areas. Gammarids used environmental variables to select warm, lentic, freshwater locations, which may help them locate an optimum microhabitat and thrive in temporally and spatially variable environments.

“…2, which showed little capacity for survival at temperatures different than 10°C, maintained a similar locomotor activity at temperatures ranging from 7 to 16°C. In addition to the technical challenge of accurately measuring the movement of these 5-mm-long arthropods in the dark, and despite numerous studies using locomotor activity as a proxy of isopods' performance (Lagerspetz and Vainio, 2006;Dailey et al, 2009;Schuler et al, 2011), mean velocity did not appear to be a pertinent indicator of the performance in Proasellus species for at least two reasons. First, mean velocities were extremely low (between 1 and 8cmmin…”

SUMMARYThe climate variability hypothesis assumes that the thermal tolerance breadth of a species is primarily determined by temperature variations experienced in its environment. If so, aquatic invertebrates living in thermally buffered environments would be expected to exhibit narrow thermal tolerance breadths (stenothermy). We tested this prediction by studying the thermal physiology of three isopods (Asellidae, Proasellus) colonizing groundwater habitats characterized by an annual temperature amplitude of less than 1°C. The species responses to temperature variation were assessed in the laboratory using five physiological variables: survival, locomotor activity, aerobic respiration, immune defense and concentrations of total free amino acids and sugars. The three species exhibited contrasted thermal physiologies, although all variables were not equally informative. In accordance with the climate variability hypothesis, two species were extremely sensitive even to moderate changes in temperature (2°C) below and above their habitat temperature. In contrast, the third species exhibited a surprisingly high thermal tolerance breadth (11°C). Differences in response to temperature variation among Proasellus species indicated that their thermal physiology was not solely shaped by the current temperature seasonality in their natural habitats. More particularly, recent gene flow among populations living in thermally constant yet contrasted habitats might explain the occurrence of eurytherm species in thermally buffered environments.
