“…One of the most valuable conclusions from recent work is that, just as trade-offs may be restricted to stressful situations in the laboratory (see above), whether seasonal time is limited or not-"time stress"-determines the structure of potential trade-offs. For example, when short photoperiods signal that the end of the season is approaching, development may accelerate in order to allow safe entry into diapause before the winter, or to allow emergence in time for reproduction, with varying influences on size and growth rate (Carrière et al, 1996;Leimar, 1996;Gotthard, 1998Gotthard, , 2001Nylin and Gotthard, 1998;Gotthard et al, 1999Gotthard et al, , 2000De Block and Stoks, 2004). When resources are limited, some species reduce developmental time with the same growth rate and so reduce size; others reduce size somewhat but maintain the same duration of development; yet others take longer to develop, but maintain size.…”

Recent work on selected topics of particular interest for understanding insect life-cycles is reviewed, including habitat patterns, kinds of variation, the spreading of risk and prolonged diapause, trade-offs and developmental plasticity, circannual rhythms, the concept of life cycles as developmental choices, and development or delay as the default response. Seasonal adaptations have a wider range of components than has often been appreciated. Variation in lifecycle traits, including the duration of development and the timing of emergence, can be wide, narrow, or discontinuous. Trade-offs encompass multiple simultaneous traits and are not always structured as might be expected. Diapause, cold hardiness, reproductive pattern, and other traits have evolved many times independently. Such complex interactions can be understood only by examining the detailed features of a species' habitat, because how developmental decisions are made and whether continuous development or delays are programmed reflect the predictability of habitats and the environmental signals they supply. Ecological context is important, not just mechanisms of adaptation. Therefore, although most previous studies have paid more attention to insect response than to habitat, interpreting the seasonal relevance of life-cycle patterns requires measurement and analysis for individual species of habitat characteristics and their variation, on a range of temporal and spatial scales, in much more detail than has been customary.

“…When confronted with such seasonal time constraints, free-living organisms with complex life cycles are often able to increase their growth rate and/or decrease their transitional size so as to switch habitats before conditions deteriorate (e.g. Leimar, 1996 ;Johansson and Rowe, 1999 ;Margraf et al 2003). Seasonal time constraints are also common in parasite life cycles.…”

Seasonal changes in host phenotype manipulation by an acanthocephalan: time to be transmitted?

et al. 2008

Many complex life cycle parasites exhibit seasonal transmission between hosts. Expression of parasite traits related to transmission, such as the manipulation of host phenotype, may peak in seasons when transmission is optimal. The acanthocephalan Acanthocephalus lucii is primarily transmitted to its fish definitive host in spring. We assessed whether the parasitic alteration of 2 traits (hiding behaviour and coloration) in the isopod intermediate host was more pronounced at this time of year. Refuge use by infected isopods was lower, relative to uninfected isopods, in spring than in summer or fall. Infected isopods had darker abdomens than uninfected isopods, but this difference did not vary between seasons. The level of host alteration was unaffected by exposing isopods to different light and temperature regimes. In a group of infected isopods kept at 4 xC, refuge use decreased from November to May, indicating that reduced hiding in spring develops during winter. Keeping isopods at 16 xC instead of 4 xC resulted in higher mortality but not accelerated changes in host behaviour. Our results suggest that changes in host and/or parasite age, not environmental conditions, underlie the seasonal alteration of host behaviour, but further work is necessary to determine if this is an adaptive parasite strategy to be transmitted in a particular season.

“…Sin embargo, todavía existe un vacío de información empírica básica que per mita hacer estimaciones cuantitativas de cómo la adecuación biológica depende del tamaño corporal, de las tasas iniciales de crecimiento (i.e., de crías o jóvenes) y del tiempo de desarrollo, bajo diferentes escenarios ecológicos o genéticos (Abrams et al 1996, Leimar 1996, Blanckenhorn 2000. Desafor tunadamente, estas estimaciones todavía son difíciles de obtener, además de la presencia de una fuer te variación de las mismas entre los organismos.…”
