“…Freshwater is becoming an increasingly important and scarce resource around the world (Yeston et al 2006). While humans have altered freshwater ecosystems through damming in the majority of large-river systems in the world (Nilsson et al 2005), there is a trend to bring flows back to a more natural regime and to recognize rivers themselves as legitimate users of water (Naiman et al 2002).…”

Floods are a key component of the ecology and management of riverine ecosystems around the globe, but it is not clear whether floods have predictable effects on organisms that can allow us to generalize across regions and continents. To address this, we conducted a global-scale meta-analysis to investigate effects of natural and managed floods on invertebrate resistance, the ability of invertebrates to survive flood events. We considered 994 studies for inclusion in the analysis, and after evaluation based on a priori criteria, narrowed our analysis to 41 studies spanning six of the seven continents. We used the natural-log-ratio of invertebrate abundance before and within 10 days after flood events because this measure of effect size can be directly converted to estimates of percent survival. We conducted categorical and continuous analyses that examined the contribution of environmental and study design variables to effect size heterogeneity, and examined differences in effect size among taxonomic groups. We found that invertebrate abundance was lowered by at least one-half after flood events. While natural vs. managed floods were similar in their effect, effect size differed among habitat and substrate types, with pools, sand, and boulders experiencing the strongest effect. Although sample sizes were not sufficient to examine all taxonomic groups, floods had a significant, negative effect on densities of Coleoptera, Eumalacostraca, Annelida, Ephemeroptera, Diptera, Plecoptera, and Trichoptera. Results from this study provide guidance for river flow regime prescriptions that will be applicable across continents and climate types, as well as baseline expectations for future empirical studies of freshwater disturbance.

“…However, the complex character of environmental issues is nowadays recognized as a multidisciplinary research challenge with interdependent variables comprising, beside other issues, the chemodynamics of pollutants and the ecological response on all levels of biological systems, from molecules to population and community level (Van den Brink 2008; Yeston et al 2006), fields that are furthermore impacted by global trends, e.g., overriding scenarios such as global climate change. From the other end, Earth system science is more and more extending into smaller spatial scales.…”

“…In the early days, one of the subjects of our research was the Engystomops frog, a tiny creature known for its brown pustular skin (1). When the lab moved from New York City to California in 1971, a young assistant named Bill was entrusted with transporting the frog colony to its new home.…”
