The impact of temperature on developmental duration of insects has been long kept a high
profile in the studies of insect pests. The relationship between developmental rate, which is …

The general effects of temperature and nutritional quality on growth rate and body size are
well known. We know little, however, about the physiological mechanisms by which an …

In animals that do not regulate their body temperature by the production of heat, the
proportion of the total developmental time spent in a particular developmental stage does …

In many organisms, individuals in colder environments grow more slowly but are larger as
adults. This widespread pattern is embodied by two well-established rules: Bergmann's rule …

The incubation of eggs is strongly influenced by temperature as observed in all species
studied to date. For example, incubation duration, sexual phenotype, growth, and …

In a recent and stimulating Forum paper, Berrigan and Charnov (1994) address the
important life-history point that the slope of the reaction norm for size-to-age at maturity in …

Countergradient variation, or the conservation of the rate of a temperature-dependent
physiological process in the face of environmental temperature change (Levins 1969; Hazel …

Thermal reaction norms of ectotherms exhibit a distinctive latitudinal pattern: the temperature
at which performance is maximized coincides with the mean habitat temperature in tropical …

Phenotypic plasticity is an important mechanism that allows populations to adjust to
changing environments. Plastic responses induced by early life experiences can have …
