The ecological impacts of the indirect effects predators are well established, but evolutionary consequences unknown. Predators often decrease prey density, which indirectly increases resources available to surviving prey. This effect could provide a link evolution because it is generally assumed that resource availability influences life history evolution. Yet, predictions from theory consider food inconsistent, and evidence for an important role in shaping absent. We compared traits...
Species that coexist in diverse natural communities interact complex ways alter each other's abundances and affect selection on traits. Consequently, predicting trait evolution may require understanding ecological evolutionary dynamics involving a number of species. In August 2016, the American Society Naturalists sponsored symposium to explore community context, focusing microevolutionary processes. Here we provide an introduction our perspectives this topic by defining context describing...
The potential of fishing mortality to cause rapid evolutionary changes in life history has received relatively little attention. By focusing only on ecological responses, standard fisheries theory and practice implicitly assume either that genetic influences the wild are negligible or natural selection adaptation is a slow process can be effectively ignored. Lack contrary evidence allowed these assumptions persist. Drawing upon >25 years research Atlantic silverside (Menidia menidia), we...
Changes in age/size-specific mortality, due to such factors as predation, have potent evolutionary consequences. However, interactions with predators commonly impact prey growth rates and food availability indirect effects may also influence change. We evaluated life-history differences Trinidadian killifish, Rivulus hartii, across a gradient predation. are located (1) "high predation" sites large piscivores, (2) "Rivulus/guppy" guppies, (3) "Rivulus-only" just Rivulus. suffer higher...
Much work has shown that the environment can induce non-genetic changes in phenotype span multiple generations. Theory predicts predictable environmental variation selects for both increased within- and across-generation responses. Yet, to best of our knowledge, there are no empirical tests this prediction. We explored relationship between versus plasticity by evaluating influence predator cues on life-history traits Daphnia ambigua . measured duration predator-induced transgenerational...
It is becoming increasingly clear that intraspecific evolutionary divergence influences the properties of populations, communities and ecosystems. The different ecological impacts phenotypes genotypes may alter selection on many species promote a cascade change throughout food web. Theory predicts interactions across trophic levels contribute to hypothesized feedbacks between ecology evolution. However, importance 'cascading change' in natural setting unknown. In lakes Connecticut, USA,...
Summary Research addressing the role of epigenetics in a diversity experimental and natural systems is rapidly accumulating. Diverse methods have been developed to study epigenetic states, including bisulphite sequencing AFLP ‐based approaches. However, existing are sometimes difficult apply non‐traditional model organisms that lack genomic resources (bisulphite sequencing), can fail be economical readily scalable diverse research questions because reliance on traditional Sanger (...
Environmental signals can induce phenotypic changes that span multiple generations. Along with responses occur during development (i.e. 'within-generation' plasticity), such 'transgenerational plasticity' (TGP) has been documented in a diverse array of taxa spanning many environmental perturbations. New theory predicts temporal stability is key driver the evolution TGP. We tested this prediction using natural populations zooplankton from lakes Connecticut large gradient dynamics...
Density-dependent selection, which promotes contrasting patterns of trait means at different population densities, has a long history in genetics and ecology. The unifying principle from theory is that density-dependent selection operates on phenotypic traits whose values counter the effects whatever ecological agent limiting growth, be it resource competition, predators, or pathogens. However, complexity inherent density dependence same selective process can generate multiple outcomes,...
Ecological factors are known to cause evolutionary diversification. Recent work has shown that evolution in strongly interacting predator species reciprocal impacts on ecosystems. These divergent of predators may alter the selective landscape and prey. Yet, this link between intraspecific variation is unexplored. We compared life history a zooplankton ( Daphnia ambigua ) from lakes New England which dominant planktivorous predator, alewife Alosa pseudoharengus ), differs feeding traits...
The impacts of predation and competition on life history, behavioral, morphological traits are well established for many organisms, but effects locomotor performance have received relatively little attention. We examined variation in sprint speed critical swimming (Ucrit, a measure stamina) the Trinidadian killifish (Rivulus hartii) across gradient ecological communities. R. hartii located (1) "high-predation" sites with large, piscine piscivores, (2) "Rivulus–guppy" guppies, (3)...
Abstract Research has shown that a change in environmental conditions can alter the expression of traits during development (i.e., “within‐generation phenotypic plasticity”) as well induce heritable responses persist for multiple generations “transgenerational plasticity”, TGP). It long been assumed shifts gene are tightly linked to observed trait at level. Yet, manner which organisms couple within‐ and TGP molecular level is unclear. Here we tested influence fish predator chemical cues on...
Abstract Anthropogenic climate change has increased the frequency of drought, wildfire, and invasions non‐native species. Although high‐severity fires linked to drought can inhibit recovery native vegetation in forested ecosystems, it remains unclear how impacts other plant communities following wildfire. We leveraged an existing rainfall manipulation experiment test hypothesis that reduced precipitation, fuel load, fire severity convert community composition from shrubs invasive grasses a...
Abstract Eco‐evolutionary experiments are typically conducted in semi‐unnatural controlled settings, such as mesocosms; yet inferences about how evolution and ecology interact the real world would surely benefit from natural uncontrolled settings. Opportunities for rare but do arise context of restoration ecology—where different “types” a given species can be introduced into “replicate” locations. Designing requires wrestling with consequential questions. (Q1) Which specific focal should to...
Disordered hemostasis associated with life-threatening hemorrhage commonly afflicts patients in the emergency department, critical care unit, and perioperative settings. Rapid sensitive phenotyping is needed to guide administration of blood components hemostatic adjuncts reverse aberrant hemostasis.

Behavioral plasticity is expected to be favored in risky environments, such as when prey species coexist with predators, because must alternate between fitness related foraging/mating behaviors and antipredator that enhance survival. We compared behavioral Trinidadian killifish are found sites without predators. quantified aggressive via a mirror assay second-generation lab-reared wild-caught before after exposure predator cues. two types of aggression including: overt (ramming, biting,...
Early theories of life-history evolution predict that increased predation on young/small individuals selects for delayed maturation and decreased reproductive effort, but such theory only considers changes in mortality. Predators reduce prey abundance increase food to survivors. Theory incorporates indirect effects yields different predictions. Trinidadian killifish, Rivulus hartii, inhabit communities with without guppies. Guppies young densities decline growth rates when guppies are...
The elemental composition of animals, or their organismal stoichiometry, is thought to constrain contribution nutrient recycling, interactions with other and demographic rates. Factors that affect stoichiometry are generally poorly understood, but likely reflect investments in morphological features life history traits, acting concert the environmental availability elements. We assessed relative traits variability an insectivorous Neotropical stream fish, Rivulus hartii. characterized...
