“…As previously described, warming tends to reduce levels of phenolics but increase levels of terpenoids in plant foliage (Zvereva and Kozlov, 2006;Bidart-Bouzat and Imeh-Nathaniel, 2008). Likewise, drought can also increase and/or decrease terpenoids (e.g.…”

(A.M.T.) Understanding and predicting the impacts of anthropogenically driven climate change on species interactions and ecosystem processes is a critical scientific and societal challenge. Climate change has important ecological consequences for species interactions that occur across multiple trophic levels. In this Update, we broadly examine recent literature focused on disentangling the direct and indirect effects of temperature and water availability on plants, phytophagous insects, and the natural enemies of these insects, with special attention given to forest ecosystems. We highlight the role of temperature in shaping plant and insect metabolism, growth, development, and phenology. Additionally, we address the complexity involved in determining climate-mediated effects on plant-insect and multitrophic level interactions as well as the roles of plant ecophysiological processes in driving both bottom-up and top-down controls. Climate warming may exacerbate plant susceptibility to attack by some insect groups, particularly under reduced water availability. Despite considerable growth in research investigating the effects of climate change on plants and insects, we lack a mechanistic understanding of how temperature and precipitation influence species interactions, particularly with respect to plant defense traits and insect outbreaks. Moreover, a systematic literature review reveals that research efforts to date are highly overrepresented by plant studies and suggests a need for greater attention to plant-insect and multitrophic level interactions. Understanding the role of climatic variability and change on such interactions will provide further insight into links between abiotic and biotic drivers of community-and ecosystem-level processes.Anthropogenic activities have led to rapid and unprecedented increases in atmospheric carbon dioxide (CO 2 ) and other greenhouse gases, which in turn have resulted in numerous observable climatic changes, such as elevated temperature, increased frequency and severity of extreme weather events (e.g. heat waves and droughts), and altered precipitation patterns (e.g. decreased snow cover) (National Research Council, 2010). Species are responding to these climate change factors, as demonstrated by shifts in phenology (the timing of key biological and life history events), biogeographic ranges, and ecological interactions (Bale et al., 2002;Parmesan and Yohe, 2003;Hegland et al., 2009;Robinson et al., 2012). In this Update, we review and discuss the consequences of climate change on plant-insect and multitrophic interactions. Specifically, we address the direct and indirect effects of climate warming and altered precipitation patterns on plants, phytophagous insects, and higher trophic level organisms. We focus on these two components of climate change, firstly, because temperature is the abiotic factor that most directly influences insects (Bale et al., 2002), and secondly, because water availability plays a prominent role in mediating plant-insect interactions (Mattso...

“…To add to dietary complexity, feeding by herbivores can influence the concentration and distribution of both chemicals and nutrients. Environmental conditions that change over short (e.g., seasons) and longtime periods (e.g., global climate change) can also influence concentrations of PSMs (Bidart-Bouzat and Imeh-Nathaniel, 2008;Lindroth, 2010) as well as toxicity of PSMs (Dearing, 2012;Dearing et al, 2008). In some cases, changes in concentration of PSMs may differ between terrestrial and aquatic systems.…”

-We describe some recent themes in the nutritional and chemical ecology of herbivores and the importance of a broad pharmacological view of plant nutrients and chemical defenses that we integrate as "Pharm-ecology". The central role that dose, concentration, and response to plant components (nutrients and secondary metabolites) play in herbivore foraging behavior argues for broader application of approaches derived from pharmacology to both terrestrial and aquatic plant-herbivore systems. We describe how concepts of pharmacokinetics and pharmacodynamics are used to better understand the foraging phenotype of herbivores relative to nutrient and secondary metabolites in food. Implementing these concepts into the field remains a challenge but new modeling approaches that emphasize tradeoffs and the properties of individual animals show promise. Throughout we highlight similarities and differences between the historic and future applications of pharm-ecological concepts in understanding the ecology and evolution of terrestrial and aquatic interactions between herbivores and plants. We offer several pharm-ecology related questions and hypotheses that could strengthen our understanding of the nutritional and chemical factors that modulate foraging behavior of herbivores across terrestrial and aquatic systems.

“…The effects of external drivers (such as global change components) on organisms can be studied by investigating the response of individuals (behavior, morphology, physiology) or populations (reproduction, survivorship) (Bale et al., 2002; Bidart‐Bouzat & Imeh‐Nathaniel, 2008). Morphological changes in response to environmental drivers are usually studied within the framework of trait‐based ecology (Deraison, Badenhausser, Loeuille, Scherber, & Gross, 2015).…”

Imaging techniques are a cornerstone of contemporary biology. Over the last decades, advances in microscale imaging techniques have allowed fascinating new insights into cell and tissue morphology and internal anatomy of organisms across kingdoms. However, most studies so far provided snapshots of given reference taxa, describing organs and tissues under “idealized” conditions. Surprisingly, there is an almost complete lack of studies investigating how an organism′s internal morphology changes in response to environmental drivers. Consequently, ecology as a scientific discipline has so far almost neglected the possibilities arising from modern microscale imaging techniques. Here, we provide an overview of recent developments of X‐ray computed tomography as an affordable, simple method of high spatial resolution, allowing insights into three‐dimensional anatomy both in vivo and ex vivo. We review ecological studies using this technique to investigate the three‐dimensional internal structure of organisms. In addition, we provide practical comparisons between different preparation techniques for maximum contrast and tissue differentiation. In particular, we consider the novel modality of phase contrast by self‐interference of the X‐ray wave behind an object (i.e., phase contrast by free space propagation). Using the cricket Acheta domesticus (L.) as model organism, we found that the combination of FAE fixative and iodine staining provided the best results across different tissues. The drying technique also affected contrast and prevented artifacts in specific cases. Overall, we found that for the interests of ecological studies, X‐ray computed tomography is useful when the tissue or structure of interest has sufficient contrast that allows for an automatic or semiautomatic segmentation. In particular, we show that reconstruction schemes which exploit phase contrast can yield enhanced image quality. Combined with suitable specimen preparation and automated analysis, X‐ray CT can therefore become a promising quantitative 3D imaging technique to study organisms′ responses to environmental drivers, in both ecology and evolution.
