The ability of organisms to perform at different temperatures could be described by a continuous nonlinear reaction norm (i.e., thermal performance curve, TPC), in which the phenotypic trait value varies as function temperature. Almost any shift parameters this curve highlight direct effect temperature on organism fitness, providing powerful framework for testing adaptation hypotheses. Inter-and intraspecific differences are also reflected tolerances limits (e.g., critical and lethal...
Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, during the rapid juvenile growth phase, food supply may play a key role in response organisms to OA. We experimentally evaluated modulating responses and biomineralization processes juveniles Chilean scallop, Argopecten purpuratus, that were exposed control (pH ~ 8.0) low pH 7.6) conditions using three treatments (high,...
Abstract The combined effect of increased ocean warming and elevated carbon dioxide in seawater is expected to have significant physiological ecological consequences at many organizational levels the marine ecosystem. In present study, juvenile mussels Mytilus chilensis were reared for 80 d a factorial combination two temperatures (12 16°C) three pCO2 (380, 700, 1000 µatm). We investigated effects increasing temperature on performance (i.e. feeding, metabolism, growth). Lower clearance rate...

Studies focusing on physiological variation among individuals, and its possible evolutionary consequences, are scarce. A trait can only be a target of natural selection if it is consistent over time, that is, must repeatable. In ectotherms has been suggested standard metabolic rate (MR) related to Darwinian fitness, since reflects energy usage expenditure. The the cricket Hophlosphyrum griseus was determined at three ambient temperatures. Repeatability MR estimated by product-moment...
We present experimental data obtained from an experiment with newly hatched veliger larvae of the gastropod Concholepas concholepas exposed to three pCO2 levels. Egg capsules were collected two locations in northern and central Chile, then incubated throughout their entire intra-capsular life cycle at nominal levels, ∼400, 700 1000 ppm (i.e. corresponding ∼8.0, 7.8 7.6 pH units, respectively). Hatched fed natural food assemblages. Food availability time zero did not vary significantly level....
Background Most research on Ocean Acidification (OA) has largely focused the process of calcification and physiological trade-offs employed by calcifying organisms to support building calcium carbonate structures. However, there is growing evidence that OA can also impact upon other key biological processes such as survival, growth behaviour. On wave-swept rocky shores ability gastropods self-right after dislodgement, rapidly return normal orientation, reduces risk predation....
Environmental temperature has profound effects on the biological performance and biogeographical distribution of ectothermic species. Variation this abiotic factor across geographic gradients is expected to produce physiological differentiation local adaptation natural populations depending their thermal tolerances sensitivities. Here, we studied variation in whole-organism physiology seven porcelain crab Petrolisthes violaceus a latitudinal gradient 3000 km, characterized by cline...
The assessment of the effects Ocean Acidifi cation (OA) on marine life has received increasing attention in recent research.On a mesocosmic scale, CO 2 levels seawater can be manipulated to evaluate experimentally consequences OA organisms (vertebrates and invertebrates).An ideal manipulation carbonate chemistry should mimic exactly changes chemistry, which will occur years come.Although some methods have been described literature, here we describe detail simple, robust inexpensive system...

Abstract Coastal biota is exposed to continuous environmental variability as a consequence of natural and anthropogenic processes. Responding heterogeneous conditions requires the presence physiological strategies cope with environment. Ecosystems influenced by upwelling endure naturally cold, acidic hypoxic conditions, nevertheless they sustain major fisheries worldwide. This suggests that species inhabiting habitats possess adaptations handle high variability. Here, we assessed impact main...
