“…Forward 1990, Boudreau et al 1991 in order to maintain aerobic metabolism and high swimming activity, emphasizes their degree of thermal specialization. Behavioral responses to temperature can help larvae to control the experienced temperature regime only within limits (Kelly et al 1982, Sulkin 1984, Forward 1990, Shanks 1995, Gardner et al 2004), due to the large-scale nature of most physical drivers of SST fluctuations (e.g. upwelling, diurnal heating, internal waves).…”

Physiological responses of larval stages can differ from those of the adults, affecting key ecological processes. Therefore, developing a mechanistic understanding of larval responses to environmental conditions is essential vis-à-vis climate change. We studied the thermal tolerance windows, defined by lower and upper pejus (Tp) and critical temperatures (Tc), of zoea I, II, and megalopa stages of the Chilean kelp crab Taliepus dentatus. Tp limits determine the temperature range where aerobic scope is maximal and functioning of the organism is unrestrained, and were estimated from direct observations of larval activity. Tc limits define the transition from aerobic to anaerobic metabolism, and were estimated from the relationship between standard metabolic rate and temperature. Zoea I showed the broadest, zoea II an intermediate, and megalopae the narrowest tolerance window (Tp). Optimum performance in megalopae was limited to Tp between 11 and 15°C, while their Tc ranged between 7 and 19°C. Although Tc may be seldom encountered by larvae, the narrower Tp temperatures can frequently expose larvae to unfavorable conditions that can drastically constrain their performance. Temperatures beyond the Tp range of megalopae have been observed in most spring and summer months in central Chile, and can have important consequences for larval swimming per formance and impair their ability to avoid predators or settle successfully. Besides the well-documented effects of temperature on development time, variability in field temperatures beyond Tp can affect performance of particular larval stages, which could drive large-scale variability in recruitment and population dynamics of T. dentatus and possibly other invertebrate species.KEY WORDS: Metabolic rate · Critical temperature · Heart beat rate · Larvae · Megalopa · Sea surface temperature · Recruitment · ZoeaResale or republication not permitted without written consent of the publisher

“…For many years, larvae were considered planktonic, that is, moving at the whim of ocean currents but using feeding and predator avoidance behaviors that resulted in small-scale (millimeters to centimeters) movements (Blaxter, 1969). The view of passive larvae gave way to the concept that vertical swimming behavior, changes in buoyancy, and ontogenetic changes in vertical position influence the horizontal movement of larvae; this view was adopted early in estuarine and coastal lagoon systems (Nelson, 1912;Pritchard, 1953;Bousfield, 1955) and later in shelf and open-ocean systems (Kelly et al, 1982;Cowen et al, 1993).…”

“…At smaller spatial scales, the aggregations of zooplankton observed in the field can occur within regions of sharp temperature gradients associated with thermal microstructure (Boyd 1973). In the laboratory, recent studies on the estuarine crabs Callinectes sapidus and Eurypanopeus depressus, and the deep sea red crab Geryon quinquedens, have shown that sharp thermal gradients have no inhibitory effect on upward movements of the hatching stage (Kelly et al 1982, Sulkin et al 1983, McConnaughey & Sullun 1984. Unfortunately, there is no information about the behavioural responses of these crab larvae in relation to the thermocline after they have reached their upper limit in the water column.…”

The behavioural responses of each planktonic stage (I to IV) of American lobster Homarus americanus to a thermal gradient were studied during complete day/night cycles using an experimental approach. The thermocline markedly influenced the vertical position of larvae of all stages, limiting their distribution to the upper part of the water column. In both absence or presence of a thermocline, older individuals (stages 111 & IV) were observed deeper in the water column than younger individuals (stages I & 11). The vertical distribution of larvae was unaffected by the day/night regime. The ecological significance of this temperature-driven behaviour of the larvae relative to the recruitment dynamics of the adult stocks is discussed. We hypothesize that factors causing a breakdown in the thermocline should decrease recruitment to the adult population. The validity of this hypothesis was explored for the lobster stock of Iles-de-la-Madeleine (Gulf of St. Lawrence, Quebec). Significant negative correlations obtained between the frequency of strong winds (> 30 km h -' ) during dispersal and settlement periods. and subsequent lobster landings (with a n 8 yr lag) in this region over a 15 yr interval support the hypothesis.
