Smaller species but larger stages
Global warming can alter size distributions of animal communities, but the contribution of size shifts within versus between species to such changes remains unknown. In particular, it is unclear if expected body size shrinkage in response to warming, observed at the interspecific level, can be used to infer similar size shifts within species. In this study, we compare warming effects on interspecific (relative species abundance) versus intraspecific (relative stage abundance) size structure of competing consumers by analyzing stage-structured bioenergetic food web models consisting of one or two consumer species and two resources, parameterized for pelagic plankton. Varying composition and temperature and body size dependencies in these models, we predicted interspecific versus intraspecific size structure across temperature. We found that warming shifted community size structure toward dominance of smaller species, in line with empirical evidence summarized in our review of 136 literature studies. However, this result emerged only given a size–temperature interaction favoring small over large individuals in warm environments. In contrast, the same mechanism caused an intraspecific shift toward dominance of larger (adult) stages, reconciling disparate observations of size responses within and across zooplankton species in the literature. As the empirical evidence for warming-driven stage shifts is scarce and equivocal, we call for more experimental studies on intraspecific size changes with warming. Understanding the global warming impacts on animal communities requires that we consider and quantify the relative importance of mechanisms concurrently shaping size distributions within and among species.

Nestwork
As more and more species fall under the threat of extinction, humans are not only taking action to protect critical habitats but are also engaging more directly with species to help mitigate their decline. Through innovative infrastructure design and by changing how we live, humans are becoming more attuned to nonhuman animals and are making efforts to live alongside them. Examining sites of loss, temporal orientations, and infrastructural mitigations, Nestwork blends rhetorical and posthuman sensibilities in service of the ecological care. In this innovative ethnographic study, rhetorician Jennifer Clary-Lemon examines human-nonhuman animal interactions, identifying forms of communication between species and within their material world. Looking in particular at nonhuman species that depend on human development for their habitat, Clary-Lemon examines the cases of the barn swallow, chimney swift, and bobolink. She studies their habitats along with the unique mitigation efforts taken by humans to maintain those habitats, including building “barn swallow gazebos” and artificial chimneys and altering farming practices to allow for nesting and breeding. What she reveals are fascinating forms of rhetoric not expressed through language but circulating between species and materials objects. Nestwork explores what are in essence nonlinguistic and decidedly nonhuman arguments within these local environments. Drawing on new materialist and Indigenous ontologies, the book helps attune our senses to the tragedy of species decline and to a new understanding of home and homemaking.

mevalonate pathway and the synthesis of juvenile hormone in insects
▪ Abstract The mevalonate pathway in insects has two important peculiarities, the absence of the sterol branch and the synthesis of juvenile hormone (JH), that may have influenced the mechanisms of regulation. The data available on these mechanisms indicate that cholesterol does not play a regulatory role and that JH modulates transcript levels of a number of genes of the mevalonate pathway or can influence the translatability and/or stability of the transcripts themselves. These data suggest that the mevalonate pathway in insects can best be interpreted in terms of coordinated regulation, in which regulators act in parallel to a number of enzymes, as occurs in the cholesterol-driven pathway in vertebrates.
