“…The American lobster has limited osmoregulatory capacity to adapt to variation in salinity (Jury et al 1994). Extreme spring rainfall can lower bottom salinity dramatically and cause severe mortality (Thomas & White 1969).…”

“…For instance, water temperature has a strong effect on survival rate, reproduction, growth and maturation (Aiken & Waddy 1986). Fluctuations of salinity can induce physiological changes that may be extremely stressful to lobster (Jury et al 1994). Wahle & Steneck (1991) suggested that local lobster density might be correlated with shelter availability.…”

“…Small lobsters are more likely to reside in inshore waters, whereas large lobsters are more common in offshore waters (Cooper et al 1975, Briggs 1985. These differences in spatial distribution are likely due to sex-and size-specific responses of lobster to the environment (Jury et al 1994, Factor 1995. Although season-, size-, and sex-specific patterns in the spatial distribution of the American lobster are prevalent, these have yet to be modeled quantitatively based on habitat and environmental variables.…”

The spatial distribution of the American lobster Homarus americanus is influenced by many factors, which are often difficult to quantify. We implemented a modeling approach for quantifying season-, size-, and sex-specific lobster spatial distribution in the Gulf of Maine with respect to environmental and spatial variables including bottom temperature, bottom salinity, latitude, longitude, depth, distance offshore, and 2 substratum features. Lobster distribution was strongly associated with temperature and depth, and differed seasonally by sex. In offshore waters in the fall, females were dominant at higher latitudes and males at lower latitudes. This segregation was not apparent in the spring although females were still dominant at higher latitudes in offshore waters. Juveniles and adults were also distributed differently; juveniles were more abundant at the lower latitudes in inshore waters, while adults were more widespread along the entire coast. These patterns are consistent with the ecology of the American lobster. This study provides a tool to evaluate changes in lobster spatial distribution with respect to changes in key habitat and other environmental variables, and consequently could be of value for the management of the American lobster.

“…Hence, it may be appropriate to assess OP toxicological impact by detecting the avoidance behavioral changes in a non-target invertebrate species. Invertebrate behavioral studies are most commonly developed [2,13,16]. The freshwater cladoceran Daphnia magna Straus are normally considered as sensitive to contaminants [23,29], and behavioral responses to contaminants were reported [11,21,30].…”

In this study, avoidance behavior of the freshwater cladoceran Daphnia magna Straus was used as indicator to assess the early stress of accidental organophosphorus pesticide (OP) contamination. The movement behavior was detected by a multi-species biomonitoring system. There was obvious concentration-response relationship between the OP stress and the behavioral response even at sublethal exposure. A rising OP stress resulted in a significant decrease of response time to escape (RTE; p<0.05). In comparison of different OPs, it was found that there was a power regression between RTE and the toxic unit of OPs. Therefore, the avoidance behavior of D. magna was a sensitive indicator of sublethal OP stress, and the power relationship could be used to predict the early warning thresholds of more OPs in the on-line biomonitoring system.

“…Differences in body mass between populations of C. moseleyi inhabiting contrasting habitats have been previously reported (Laparie et al 2012), but seem unrelated to body water content. Mechanisms other than bulk water storage, such as metabolic water storage (Gibbs et al 1997) or behavioural avoidance (Jury et al 1994), may account for differences in the response to dehydration stress of the two ecophenotypes and require further investigation.…”

Water conservation is a critical aspect affecting the survival, distribution and abundance of terrestrial arthropods. In this study we investigate mechanisms of dehydration tolerance of the native, flightless fly, Calycopteryx moseleyi, inhabiting contrasting environments at two localities in the Kerguelen Islands. We compare the survival abilities and management of body water content of adult flies from two different ecophenotypes when exposed to conditions of low relative humidity. Our results suggest a broad plasticity in the responses of C. moseleyi to desiccation, showing distinct local adaptations to environmental conditions.
