Biological invasions are a prominent factor contributing to global biodiversity loss. As a result, managing invasive species is a priority for many conservation scientists and natural resource managers. Invasive species management requires a multidisciplinary approach and there is increasing recognition that physiology can be used to inform conservation efforts because physiological processes underlie an individual's response to its environment. For example, physiological concepts and tools can be used to assess the impacts of invasive animals on their new ecosystems, to predict which animal species are likely to become invasive, to prevent the introduction of nonnative animals, and to control incipient or established invasions. To evaluate whether physiology is integrated within invasion science, the journal Biological Invasions was surveyed for a quantitative literature review. To determine how physiology is used to inform invasion science and which subdisciplines of physiology are particularly relevant to invasive animal management, the broader invasion literature was also reviewed to identify examples where physiology has contributed to studying and managing invasive animals. Only 6 % of articles published in Biological Invasions incorporated physiological knowledge or tools, mostly for the purposes of identifying traits associated with species invasiveness (i.e. prediction). However, the broader literature indicated that successful invasive species research and management can be supported by fundamental and applied physiological research for assessing, predicting, preventing, and controlling invasive animals. Development of new techniques and increased availability of equipment for remote or rapid monitoring of physiology in the field will increase opportunities for integrating physiology within invasion science.

“…Although we only sampled one known location of bigheaded carps' hybrids at one single point in time, it was from a location known to contain a high proportion of bigheaded carps and their hybrids (Lamer et al 2015). Nutritional trends for bigheaded carps may differ under varying environmental conditions and across seasons (Liss et al 2013); however, the nutritional parameters selected for this study were chosen because they represent a long-term body energy reserve nutritional component (Wagner & Congleton 2004;Congleton & Wagner 2006). Additionally, a longterm study by Sass et al (2014) observed a strong and consistent pattern between the presence of bigheaded carps and the zooplankton community of the Illinois River.…”

Hybridization can influence a range of characteristics and outcomes for an organism; however, relatively little is known about evolutionary consequences on nutritional performance. Information on hybrid nutritional performance would provide an understanding of how hybrids interact with their environment and insights into mechanisms affecting survival. Our goal was to test for relationships between hybridization and nutritional performance in invasive bigheaded carps (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), and their hybrids in the Marseilles reach of the Illinois River, Illinois, USA. Silver carp showed better nutritional performance relative to bighead carp. Early generation bighead and silver carp hybrid groups were intermediate to both parental lines, thereby, reducing their nutritional performance, and advanced generation bighead and silver carp groups were nutritionally more similar to their respective parental species. Differences in gill raker morphology and feeding habits among bigheaded carps and their hybrids are plausible mechanisms explaining observed nutritional performance patterns. In addition to providing unique insights about how hybridization influences the nutritional performance of wild organisms relative to parentals, our findings may have management implications for bigheaded carps if interbreeding persists over time and reduced nutritional performance is further manifested by continued hybridization.

“…First, a principal component analysis (PCA) was performed, and principal components (PCs) with eigenvalues 11 were interpreted for analysis (Kaiser 1960). For the FA, these PCs were rotated using varimax rotation on the maximum likelihood solution (Kaiser 1960;Liss et al 2013). Variables with factor loadings 1F0.4F were considered maximal contributors to each factor (Kaiser 1960;Liss et al 2013).…”

“…After the 25-min confinement in the fish bag, M. salmoides were bled a second time in a manner identical to that of the first before being weighed, measured, fin-clipped to prevent resampling, and released. Immediately following withdrawal, extracted blood samples were spun in a centrifuge for 3 min at 6,000 rpm to separate plasma from erythrocytes (Liss et al 2013). Following centrifugation, the plasma layer was removed and divided into two other microcentrifuge tubes.…”

Watershed-Scale Land Use Activities Influence the Physiological Condition of Stream Fish

Land use changes within watersheds can have large effects on stream ecosystems, but the mechanistic basis of those effects remains poorly understood. While changes to population size presumably reflect underlying variation in organismal health and condition, such individual-level metrics are rarely evaluated in the context of ecosystem disturbance. To address this deficiency, we combined physiological sampling with geographic information systems to quantify the effects of land use on physiological indicators of health in largemouth bass. More specifically, we first quantified blood metrics relating to nutrition, oxidative stress, and the glucocorticoid stress response from largemouth bass residing in eight watersheds. We then used Akaike's information criterion to define relationships between these blood metrics and land cover, including forests, agricultural areas, urban areas, and wetlands. The proportion of forest cover in a watershed was the best predictor of blood metrics representing recent feeding and resistance to oxidative stress, whereas the proportion of wetlands was the best predictor of glucocorticoid function; however, further investigation is needed, as the explanatory power of the models was relatively low. Patterns in energy reserves were not influenced by any land use practices. Interestingly, anthropogenic land use categories, such as urban and agricultural areas, were not the best predictor for any blood metrics. Together, our results indicate that fish health is most related to natural features of a landscape rather than anthropogenic land uses. Furthermore, these findings suggest that physiological methods could supplement traditional population and community assessments to develop a more comprehensive understanding of ecosystem interactions and improve stream management.
