Sampling a pika’s pantry: Temporal shifts in nutritional quality & over-winter preservation of American pika food caches
Climate change is increasing temperature, decreasing precipitation, and increasing atmospheric CO2 concentrations in many ecosystems. As atmospheric carbon rises, plants may increase carbon-based defenses such as phenolics, thereby potentially affecting food quality, foraging habits, and habitat suitability for mammalian herbivores. In alpine habitats, the American pika (Ochotona princeps) is a model species for studying effects of changing plant chemistry on mammals. To survive between growing seasons, pikas cache “haypiles” of plants rich in phenolics. Although they are acutely toxic to pikas, phenolic compounds help plants retain biomass and nutrition during storage, and they break down over time. Alpine avens (Geum rossii, Rosales: Rosaceae) is a high-phenolic plant species that comprises up to 75% of pika winter diet in Colorado. Here, we tested the hypothesis that contemporary climate change has affected the nutritional value of Alpine avens to pikas in the last 30 years. Specifically, we compared phenolic activity, nutritional quality, and overwinter preservation of plants collected at Niwot Ridge, Colorado (USA) in 1992 to those collected between 2010 – 2018, spanning nearly three decades of climate change. Phenolic activity increased in alpine avens since 1992, while fiber and nitrogen content decreased. Importantly, overwinter preservation of plant biomass also increased, particularly on windblown slopes without long-lasting snow cover. Previous studies indicate that pikas at this site still depend on alpine avens in their winter food caches. Increasing phenolic content in alpine avens could therefore enhance the preservation of haypiles over winter; however, if pikas must further delay consuming these plants to avoid acute toxicity, then he nutritional gains from enhanced preservation may not be beneficial. This study provides important insights into how changing plant chemistry will affect mammalian herbivores in the future.

Full list of publications dealing with resources nutritional quality in ecology
<p><span>Our understanding of ecosystem functioning is strongly linked to the study of predator-prey relationships and food web structures. However, trophic ecology has often focused on identifying taxonomic relationships and quantifying the biomass or energy ingested by consumers, but has often failed to integrate the importance of the nutritional quality of resources in ecological dynamics. Underlying this gap is the multi-dimensional nature of resource quality which has hampered any consensus on the definition of resource nutritional quality. In this special issue, we aimed at gathering a subset of articles exemplifying the diversity of variables by which resources quality is quantified, the diversity of research topics that can be tackled in ecology - from physiological or evolutionary aspects to ecosystem processes - and propose some perspectives on the integration of nutritional quality within broader ecological concepts. Using a semi-automated literature analysis, we map the current landscape of the "resources nutritional quality" research of the last 30 years. We depict how it has been quantified through physical, biological or chemical indicators, the use of these parameters being largely dependent on the type of ecosystem studied and on the investigated ecological process. We then position t</span><span>he articles published in this special issue of Oikos within this landscape, showing they cover a small but relatively well representative subset of the domains of resources quality-related issues. Articles in this special issue browse a range of individual and population-level approaches (embracing evolutionary questions) to community related questions, include methodological issues and ecosystem-wide approaches using trophic quality indicators as tracers of resources origin. Based on these studies and on the literature review, we identify a non-exhaustive list of challenges and perspectives of research that we consider of highest priority in the large topic of trophic ecology.</span></p>

Longitudinal variation in the nutritional quality of basal food sources and its effect on invertebrates and fish in subalpine rivers
<p><span><span>1. There is growing recognition of the importance of food quality over quantity for aquatic consumers. In streams and rivers, most previous studies considered this primarily in terms of the quality of terrestrial leaf litter and importance of microbial conditioning. However, many recent studies suggest that algae are a more nutritional food source for riverine consumers than leaf litter. To date, few studies have quantified longitudinal shifts in the nutritional quality of basal food resources in river ecosystems and how these may affect consumers.</span></span></p> <p><span><span>2. We conducted a field investigation in a subalpine river ecosystem in Austria to investigate longitudinal variations in diet quality of basal food sources (submerged leaves and periphyton) and diet source dependence of stream consumers (invertebrate grazers, shredders, filterers and predators, and fish). Fatty acid (FA) profiles of basal food sources and their consumers were measured.</span></span></p> <p><span><span>3. Our results indicate systematic differences between the FA profiles of terrestrial leaves and aquatic biota, i.e., periphyton, invertebrates and fish. Submerged leaves contained very low proportions of long-chain polyunsaturated fatty acids (LC-PUFA), which were conversely rich in aquatic biota. While the FA composition of submerged leaves remained similar among sites, the LC-PUFA of periphyton increased longitudinally, which was associated with increasing nutrients from upstream to downstream.</span></span></p> <p><span><span>4. Longitudinal variations in periphyton LC-PUFA were reflected in the LC-PUFA of invertebrate grazers and shredders, and further tracked by invertebrate predators and fish. However, brown trout (<i>Salmo trutta</i>) contained a large proportion of docosahexaenoic acid (DHA, 22:6ω3), a LC-PUFA almost entirely missing in basal sources and invertebrates. The fish accumulated eicosapentaenoic acid (EPA, 20:5ω3) from invertebrate prey and may use this FA to synthesize DHA.</span></span></p> <p><span><span>5. Our results provide a nutritional perspective for river food web studies, emphasizing the importance of algal resources to consumer somatic growth and the need to account for the longitudinal shifts in the quality of these basal resources.</span></span></p>
