1. Ponds and pools, broadly defined in this paper to include all small shallow standing waters that permanently or temporarily contain water, are numerous, diverse important from a conservation point of view. We here argue ponds pools offer powerful potential for studies ecology, evolutionary biology biology. 2. An outline is given the characteristics make them good model systems large-scale surveys hypothesis testing through experimental manipulation. Such will not only increase...
Anthropogenic environmental changes, or ‘stressors’, increasingly threaten biodiversity and ecosystem functioning worldwide. Multiple-stressor research is a rapidly expanding field of science that seeks to understand ultimately predict the interactions between stressors. Reviews meta-analyses primary scientific literature have largely been specific either freshwater, marine terrestrial ecology, ecotoxicology. In this cross-disciplinary study, we review state knowledge within among these...
Abstract The increasing urbanization process is hypothesized to drastically alter (semi‐)natural environments with a concomitant major decline in species abundance and diversity. Yet, studies on this effect of urbanization, the spatial scale at which it acts, are present inconclusive due large heterogeneity taxonomic groups scales relationship has been investigated among studies. Comprehensive analysing across multiple animal rare, hampering assessment how biodiversity generally responds...
Worldwide, urbanization leads to tremendous anthropogenic environmental alterations, causing strong selection pressures on populations of animals and plants. Although a key feature urban areas is their higher temperature ("urban heat islands"), adaptive thermal evolution in organisms inhabiting has rarely been studied. We tested for tolerance (CTMAX ) the water flea Daphnia magna, keystone grazer freshwater ecosystems, by carrying out common garden experiment at two temperatures (20°C 24°C)...
Although complex life cycles are widespread, we know little about how constraints in the larval stage influence adult fitness. Most models assume a tight coupling of conditions and fitness through size timing history transition. However, there few empirical tests this assumption. We combined an experimental manipulation environment with subsequent study fitness, measured as lifetime mating success. Individuals damselfly Lestes viridis were followed from egg to reproduction death. Under time...
Summary Despite its prominent role in life‐history theory, there is no direct empirical evidence for a behaviourally mediated predation cost of rapid growth. Moreover, we know little about how digestive physiology may also influence the shape growth/predation risk trade‐off function. We determined behaviour and experiments which damselfly larvae were induced to grow slowly or rapidly by manipulating photoperiod (time stress), exposure fish predator. showed that under time stress grew more...
1 Despite its wide ecological relevance, we know little about the physiological mechanisms underlying growth vs. mortality by predation trade-off. Here, test for two costly, potential correlates of fight-or-flight response that may contribute to reduction under risk: induction stress proteins (Hsp60 and Hsp70) antioxidant enzymes (superoxide dismutase, SOD catalase, CAT), in larvae damselfly Enallagma cyathigerum. 2 Under risk, there was a an increase oxygen consumption, indicative response....
Optimal values for life history traits are expected to depend upon environmental conditions during development and the period within which is constrained (e.g., biotic factors time constraints, respectively). Theory predicts that responses both constraints may be direct behaviorally mediated. Few experimental studies of histories have considered joint effects fewer still been able disentangle from mediated effects. We studied such interactions by manipulating perceived onset winter,...
Physiological costs of compensatory growth are poorly understood, yet may be the key components in explaining why rates typically submaximal. Here we tested hypothesized direct terms oxidative stress. We assessed stress a study where generated body mass by exposing larvae damselfly Lestes viridis to transient starvation period followed ad libitum food. Compensatory larval stage was associated with higher (as measured induction superoxide dismutase and catalase) adult stage. Our results...
Abstract We integrated the evidence for evolutionary and plastic trait changes in situ response to climate change freshwater invertebrates (aquatic insects zooplankton). The synthesis on expected reductions hydroperiod increases salinity indicated little adaptive, plastic, genetic local adaptation. With respect responses temperature, there are many studies temporal phenology body size wild that believed be driven by temperature increases, but is a general lack of rigorous demonstration...
Little is known about physiological costs of rapid growth. We successfully generated compensatory growth to time stress and transient food in the damselfly Lestes viridis studied correlates resulting reduced ability cope with starvation. found evidence for both mechanisms proposed underlie trade-off: was associated (1) a higher metabolic rate, as indicated by oxygen consumption faster depletion energy storage molecules (glycogen triglycerides), (2) smaller investment storage. The former may...
Abstract Global warming and its associated increase in temperature extremes pose a substantial challenge on natural systems. Tropical ectotherms, living close to their (upper) critical thermal limits, may be particularly vulnerable global warming, yet they are as group understudied. Most studies assessing fitness effects under focused life‐history correlates such body size largely neglected immune function. Furthermore did not consider what extent modulated resource‐based trade‐offs. Against...
Abstract We need to understand joint ecological and evolutionary responses climate change predict future threats biological diversity. The ‘evolving metacommunity’ framework emphasizes that interactions between mechanisms at both local regional scales will drive community dynamics during change. Theory suggests often interact produce outcomes different from those predicted based on either mechanism alone. highlight two of these dynamics: (i) species prevent adaptation nonresident new niches...
Abstract The field of eco‐evolutionary dynamics is developing rapidly, with a growing number well‐designed experiments quantifying the impact evolution on ecological processes and patterns, ranging from population demography to community composition ecosystem functioning. key challenge remains transfer insights these proof‐of‐principle natural settings, where multiple species interact are far more complex than those studied in most experiments. Here, we discuss potential pitfalls building...
Abstract Purpose of Review Global warming and pollution are among the five major causes global biodiversity loss, particularly in aquatic invertebrates which highly diverse but understudied. In this review, we highlight advancements current environmental studies investigating interactive effects between contaminants freshwater marine invertebrates. We not only focused on temperate regions also synthesized information less studied Arctic/Antarctic tropical regions. Recent Findings general,...
Invasive alien (IA) predators pose significant threats to native ecosystems, often leading profound impacts on prey species through both direct and non-consumptive effects (NCE). This study focused the NCE of predator-induced stress from one crayfish species, noble ( Astacus astacus ), compared danube Pontastacus leptodactylus ) two IA signal Pacifastacus leniusculus spinycheek Faxonius limosus damselfly Ischnura elegans . We investigated cue effect egg traits as well potential carry-over...
Abstract We investigated four predictions about how temperature, photoperiod and sex affect the life history plasticity foraging activity of a damselfly. (i) As predicted, increased temperatures growth rates, but in contrast with prediction, late (high time stress) did not rate. (ii) Unexpectedly, increase rate at increasing was larger under high stress. (iii) age size emergence decreased higher photoperiod. Temperature-induced shifts were direct or result behavioural mediation depending on...
The simultaneous presence of predators and a limited time for development imposes conflict: accelerating growth under constraints comes at the cost higher predation risk mediated by increased foraging. few studies that have addressed this trade-off dealt only with life history traits such as age size maturity. Physiological largely been ignored in assessing impact environmental stressors, it is unknown whether they respond independently traits. Here, we studied effects constraints, i.e.,...
Survey data from New England showed that assemblages of Lestes damselflies are organized along the entire gradient pond permanence and predator presence. One assemblage occupies vernal ponds lacking large dragonfly predators fish; four largely confined to temporary typically contain predators; one dominates fishless permanent lakes where dragonflies top fish predators. We determined role life history predation in maintaining this striking pattern by conducting a series transplant experiments...
In a large behavioral experiment we reconstructed the evolution of responses to predators explore how interactions with have shaped their prey's behavior. All Enallagma damselfly species reduced both movement and feeding in presence coexisting predators. Some inhabit water bodies fish dragonflies, these responded predators, whereas other that only dragonflies as dragonflies. Lineages shifted live showed no behaviors expressed but they evolved greater absence fish. These results suggest...
