We investigated the evolutionary response of an ecologically important freshwater crustacean, Daphnia, to a rapidly changing toxin environment. From the 1920s until the 1960s, the use of leaded gasoline caused the aquatic concentration of Pb to increase at least fivefold, presumably exerting rapid selective pressure on organisms for resistance. We predicted that Daphnia from this time of intense pollution would display greater resistance than those hatched from times of lower pollution. This… Expand
Thermal evolution offsets the elevated toxicity of a contaminant under warming: A resurrection study in Daphnia magna
TLDR
The results suggest that the increased sensitivity to the sublethal concentration of nZnO under the predicted 4°C warming by the end of this century may be counteracted by thermal evolution in this D. magna population, illustrating the importance of evolution to warming in shaping the responses to another anthropogenic stressor, here a contaminant. Expand
Reversed evolution of grazer resistance to cyanobacteria
TLDR
It is shown here that the subsequent reduction in nutrient input, accompanied by a decrease in cyanobacteria, resulted in the re-emergence of highly susceptible Daphnia genotypes, a rare example of reversed evolution of a fitness-relevant trait in response to relaxed selection. Expand
Metal stress in zooplankton diapause production: post-hatching response
TLDR
It is shown that sub-lethal concentrations of copper affected traits related to sexual reproduction and diapausing egg production in the rotifer, suggesting that rapid initiation of mixis is promoted in risky environments, and an adaptive advantage of populations from natural sediments exposed to copper is suggested. Expand
Rapid evolution in response to warming does not affect the toxicity of a pollutant: Insights from experimental evolution in heated mesocosms
TLDR
Evaluating whether thermal evolution influences the toxicity of pollutants is important for ecological risk assessment and provides key information to extrapolate laboratory‐derived toxicity estimates of pollutants both in space to warmer regions and in time under future global warming scenarios. Expand
Resistance of Dormant Eggs of Cladocera to Anthropogenic Pollutants
TLDR
To predict the effect of contamination of bottom sediments by different pollutants on the ecosystem structure and functioning, it is highly important to investigate the viability of the resting eggs under a wide range of concentrations of various toxicants and different durations of direct contact of eggs with toxicants. Expand
Assessment of biochemical mechanisms of tolerance to chlorpyrifos in ancient and contemporary Daphnia pulicaria genotypes.
TLDR
Findings suggest that pathways involving Phase-I detoxification and/or bioactivation of chlorpyrifos play a significant role in dictating the microevolutionary trajectories of tolerance in this population of Daphnia pulicaria. Expand
Does geographic variation in thermal tolerance in Daphnia represent trade-offs or conditional neutrality?
TLDR
Geographic variation in thermal tolerance in Daphnia seems to represent genetic load at the loci specifically responsible for heat tolerance resulting from conditional neutrality, and pervasive positive correlations between fitness-related traits indicate differences in genetic load rather than trade-off based local adaptation or thermal specialization. Expand
Multi-generational exposure to Pb in two monophyletic Daphnia species: Individual, functional and population related endpoints.
TLDR
Data show an acclimation under a generational Pb exposure, which could increase the population of adapted organisms in natural habitats, and an indication of epigenetic changes for both species may also be considered. Expand
Stoichiometric responses to nano ZnO under warming are modified by thermal evolution in Daphnia magna.
TLDR
The results indicate that the stoichiometric responses to nZnO in Daphnia are temperature-dependent and modified by rapid evolution, which may affect the food quality of this important prey and have the potential to cascade through food webs and shape nutrients cycling. Expand
Sedimentary and egg-bank DNA from 3 European lakes reveal concurrent changes in the composition and diversity of cyanobacterial and Daphnia communities
TLDR
The recent re-oligotrophication of the lakes did not reverse the cyanobacterial and Daphnia assemblages to their pre-eutrophication composition and genetic structure, suggesting that both changed irreversibly due to anthropogenic influence on the ecosystems. Expand

Life-history consequences of adaptation to pollution. “Daphnia longispina clones historically exposed to copper”
TLDR
Higher respiration rates of the most resistant clone support in part the energy cost hypothesis of tolerance, whereas increase feeding, reproduction and growth rates across copper exposure levels may also, indicate that resistant individuals need copper to fulfil they physiological demands thus supporting the metal deficiency hypothesis as well.

Rapid Evolution of Metal Resistance in a Benthic Oligochaete Inhabiting a Metal-polluted Site
TLDR
A case of very rapid evolution of resistance in a common freshwater benthic invertebrate, to sediment with extremely high levels of cadmium and nickel, to metal-polluted sites in Foundry Cove was identified. Expand
A millennial-scale chronicle of evolutionary responses to cultural eutrophication in Daphnia.
TLDR
Using this resurrection ecology approach, environmental, genetic and phenotypic data spanning pre- and post-industrialised agricultural eras clearly reveal the evolutionary consequences of anthropogenic environmental change. Expand
Tainted resurrection: metal pollution is linked with reduced hatching and high juvenile mortality in Daphnia egg banks.
TLDR
There was a robust positive relationship between sediment metal concentrations and juvenile mortality in Daphnia hatching from those sediments, and exposure to metals may impose strong selection on DAPHnia diapausing egg banks. Expand
Evolutionary shifts in copepod acid tolerance in an acid-recovering lake indicated by resurrected resting eggs
TLDR
Zooplankton resting eggs were employed to track population-level shifts in acid tolerance over the last century in a boreal shield lake recovering from acidification to suggest support for the hypothesis that nauplii hatched from eggs deposited during the period of acidification in George Lake had reduced variation in pH tolerance compared to the recovery period.

Long–term genetic shifts in a microcrustacean egg bank associated with anthropogenic changes in the Lake Constance ecosystem
TLDR
The results indicate that significant shifts have occurred in the genetic structure of this population of zooplankton, which parallel concomitant shifts in the trophic state of Lake Constance during the past 25–35 years. Expand
The impact of human-made ecological changes on the genetic architecture of Daphnia species
TLDR
This work reconstructed the genetic architecture of a Daphnia species complex in 2 European lakes using diapausing eggs that were isolated from sediment layers covering the past 100 years to demonstrate that anthropogenically induced temporal alterations of habitats are associated with long-lasting changes in communities and species.

Lake ecosystems: Rapid evolution revealed by dormant eggs
TLDR
It is shown that the mean resistance of Daphnia genotypes to dietary cyanobacteria increased significantly during this eutrophication of Lake Constance, which has implications for the ways that ecosystems respond to nutrient enrichment through the impact of grazers on primary production. Expand

TLDR
The fact that the evolution of resistance to environmental pollutants does seem to occur in some populations in polluted environments warrants taking that possibility into consideration when evaluating the results of bioassays and monitoring programs. Expand

This study demonstrates a genetic approach to the study of ecological restoration and connects a genetic indicator of restoration to transfer of toxic metals through ecosystems. Expand
