Allocation Strategies

Survival in variable environments often requires careful allocation of resources to competing physiological and behavioral functions. Because these competing processes often have additive energetic costs (Hawley et al. 2012), a limited resource pool forces individuals to make difficult trade-off decisions regarding energetic investments (Lochmiller and Deerenberg 2000). These trade-offs are a cornerstone of life-history theory that is aimed at determining the optimal allocation strategies in variable environments (Ricklefs and Wikelski 2002), and understanding their physiological and ecological consequences has renewed poignancy in the face of the unprecedented rate of anthropogenic environmental change occurring across the planet.

And Control

The increased awareness of the exploitation of resources, as well as the negative ecological consequences of the modern way of life, has made sustainability a central guiding concept of social change in the 21st century. Sustainability has taken the form of a largely undisputed normative model of development, behind which, however, very different conceptions of the future are concealed: from the attempt to initiate a major socio-ecological transformation, through modernization processes, to control practices in a state of emergency. This special issue aims at these practices but is not primarily concerned with sustainability as a normative guiding idea that can just be pursued. However, a sociology of sustainability has to ask which conflictual spaces of possibility for socioeconomic change open up when very different ideas of a sustainable future are in conflict with each other. Three ideal-typical trajectories or futures of sustainability emerge, which can be theoretically grasped with the terms modernization, transformation and control. These three concepts of a sustainable future can also be found in the ambivalent imaginations, practices and structures of various constellations of actors.

The Relationship

Developmental plasticity can elicit phenotypic adjustments that help organisms cope with environmental change, but the relationship between developmental plasticity and plasticity in adult life (e.g., acclimation) remains unresolved. We sought to examine developmental plasticity and adult acclimation in response to hypoxia of aerobic capacity (V̇O2max) for thermogenesis in deer mice (Peromyscus maniculatus) native to high altitude. Deer mice were bred in captivity and exposed to normoxia or one of four hypoxia treatments (12 kPa O2) across life stages: adult hypoxia (6–8 weeks), post-natal hypoxia (birth to adulthood), life-long hypoxia (before conception to adulthood), and parental hypoxia (mice conceived and raised in normoxia, but parents previously exposed to hypoxia). Hypoxia during perinatal development increased V̇O2max by a much greater magnitude than adult hypoxia. The amplified effect of developmental hypoxia resulted from physiological plasticity that did not occur with adult hypoxia – namely, increases in lung ventilation and volume. Evolved characteristics of deer mice enabled developmental plasticity, because white-footed mice (P. leucopus; a congener restricted to low altitudes) could not raise pups in hypoxia. Parental hypoxia had no persistent effects on V̇O2max. Therefore, developmental plasticity can have much stronger phenotypic effects and can manifest from distinct physiological mechanisms from adult acclimation.
