Trade‐Offs in Thermal Adaptation: The Need for a Molecular to Ecological Integration*
This effort illustrates the need for an overarching concept of thermal adaptation that encompasses molecular, organellar, cellular, and whole‐organism information as well as the mechanistic links between fitness, ecological success, and organismal physiology. Expand
Intrapopulational variation in the standard metabolic rate of insects: repeatability, thermal dependence and sensitivity (Q10) of oxygen consumption in a cricket
The results suggest that MR could be of selective value in insects, showing consistency over time and intrapopulational variability in its thermal dependence, Nevertheless, its heritability remains to be determined. Expand
Metabolism and life-history correlates in a lowland and highland population of a terrestrial isopod
Differences in VO2 between the populations contributed to the difference in reproductive output by wood lice from cold and warm habitats, and the metabolic cold-adaptation hypothesis was not supported. Expand
The energetics of reproduction and parental care in the terrestrial isopod Porcellio laevis.
The results presented here show that the parental care provided by female P. laevis is energetically costly and both proximal mechanisms and consequences of providing care on future reproduction, should be considered in explaining the evolution of parental care. Expand
Species-specific responses to ocean acidification should account for local adaptation and adaptive plasticity
A simple index taking into account the natural pCO2 variability is proposed, for a better interpretation of the potential consequences of ocean acidification on species inhabiting variable coastal ecosystems. Expand
Impact of medium-term exposure to elevated pCO(2) levels on the physiological energetics of the mussel Mytilus chilensis.
The results of this study clearly indicate that high pCO(2) levels in the seawater have a negative effect on the health of M. chilensis, and the predicted acidification of seawater associated with global climate change could be harmful to this ecologically and commercially important mussel. Expand
Species composition and distribution of decapod crustaceans in the waters off Patagonia and Tierra del Fuego, South America
SUMMARY: This paper comprises the decapod crustacean material collected during the “Victor Hensen” campaign 1994 and during the last phase of “Polarstern” cruise ANT XIII/4 in 1996. Sampling coveredExpand
Egg production in Betaeus emarginatus (H. Milne Edwards, 1837) (Decapoda: Alpheidae): fecundily, reproductive output and chemical composition of eggs
The snapping shrimp Betaeus emarginatus from central-southern Chile produced numerous and relatively large eggs, which more than double in volume during embryogenesis and corroborate the tendency of decreasing RO with increasing latitude. Expand
Genetic variation for plasticity in physiological and life-history traits among populations of an invasive species, the terrestrial isopod Porcellio laevis
The results support the hypothesis that phenotypic plasticity itself is an adaptive response to environmental heterogeneity and there is genetic variation for plasticity in response to the environment, which may be acted upon by natural selection. Expand
Latitudinal variation in the reproductive biology of the commensal crab Pinnaxodeschilensis (Decapoda: Pinnotheridae) along the Chilean coast
Results demonstrated significant differences in egg number, egg volume, dry egg weight, and reproductive output of ovigerous females, between the studied populations of northern and central-southern Chile. Expand
