“…The body size of P. constricticollis did not show simple clinal variation, as is expected based on local adaptation to temperature conditions and a fixed life cycle (voltinism;Masaki, 1967;Roff, 1980). Because Tominaga (1988) mentioned the possibility of selection for large body size in areas with deep snow (see also Ego et al, 1988), we tested the effect of climatic factors, including temperature, rainfall, and snowfall, on body and ovipositor dimensions, and found that only depth of snow had a consistent positive effect on these dimensions.…”

“…Geographic variation in insect body size reflects the differential adaptation of local populations to local environmental conditions such as climatic factors, food availability, and the presence of related species (Masaki, 1967(Masaki, , 1978Roff, 1980;Mousseau & Roff, 1989;Blanckenhorn & Fairbairn, 1995;Sota et al, 2000a, b). As body parts are particularly important in the adaptation to habitat and food conditions, the ovipositor and associated structures also show marked geographic variation in response to abiotic conditions (Masaki, 1979(Masaki, , 1986Bradford et al, 1993;Mousseau & Roff, 1995) and host plant morphology (e.g., Toju & Sota, 2006a, b).…”

Abstract. Plateumaris constricticollis is a donaciine leaf beetle endemic to Japan, which lives in wetlands and uses Cyperaceae and Poaceae as larval hosts. We analyzed geographic variation in body size and ovipositor dimensions in three subspecies (constricticollis, babai, and toyamensis) in different climatic conditions and on different host plants. In addition, the genetic differentiation among subspecies was assessed using nuclear 28S rRNA gene sequences. The body size of subspecies toyamensis is smaller than that of the other subspecies; mean body size tended to increase towards the northeast. Ovipositor length and width are smaller in subspecies toyamensis than in the other subspecies. Although these dimensions depend on body size, ovipositor length still differed significantly between toyamensis and constricticollis-babai after the effect of body size was removed. Multiple regression analyses revealed that body size and ovipositor size are significantly correlated with the depth of snow, but not temperature or rainfall; sizes were larger in places where the snowfall was greatest. Haplotypes of the 28S rRNA gene sequence were not shared among the subspecies. Subspecies constricticollis and babai each had a unique haplotype, whereas subspecies toyamensis had four haplotypes, indicating differentiation among local populations within toyamensis. The evolution of body and ovipositor size in relation to habitat conditions and host plants is discussed.

“…Nevertheless, the age-size compromise may influence the type or magnitude of evolutionary change in phenology that would be expected in response to a warming climate (Etterson & Shaw 2001). In annual plants, for example, there is frequently a positive genetic correlation between age and size at flowering (Mitchell-Olds 1996;Franks & Weis 2008); in insects, many of which are likewise annuals, later metamorphosis to adulthood means more time for growth (Masaki 1967). In both cases, the optimal phenological response to an extended growing season depends on the relative benefits of reaching reproductive maturity earlier in the season or growing larger before reproducing.…”

Phenology affects nearly all aspects of ecology and evolution. Virtually all biological phenomenafrom individual physiology to interspecific relationships to global nutrient fluxes-have annual cycles and are influenced by the timing of abiotic events. Recent years have seen a surge of interest in this topic, as an increasing number of studies document phenological responses to climate change. Much recent research has addressed the genetic controls on phenology, modelling techniques and ecosystem-level and evolutionary consequences of phenological change. To date, however, these efforts have tended to proceed independently. Here, we bring together some of these disparate lines of inquiry to clarify vocabulary, facilitate comparisons among habitat types and promote the integration of ideas and methodologies across different disciplines and scales. We discuss the relationship between phenology and life history, the distinction between organismal-and population-level perspectives on phenology and the influence of phenology on evolutionary processes, communities and ecosystems. Future work should focus on linking ecological and physiological aspects of phenology, understanding the demographic effects of phenological change and explicitly accounting for seasonality and phenology in forecasts of ecological and evolutionary responses to climate change.

We investigated the genetic background of intraspecific variation in wing color across an elevational gradient in the butterfly Colias philodice eriphyle. The degree of wing melanization was an accelerating function of elevation, and differences in wing melanization persisted in a common environment. Full‐sibling analysis and parent‐offspring regression yielded consistent, moderate to high heritabilities for the degree of wing melanization. The breeding experiments also demonstrated that wing melanization is strongly sex linked. Because traits that differentiate sister species also tend to be sex linked, our results suggest that the genetic mechanisms underlying intraspecific differences in wing melanization are not fundamentally different from those that have been shown to differentiate sister species.
