“…Laboratory selection experiments that manipulated temperature have yielded results that mimic the life-history differences observed in Daphnia between anadromous lakes and the other lakes. Populations of Drosophila that were reared under a cold temperature for multiple generations evolved faster rates of growth and development than the warmtemperature lines ( [27,28], but see [45]). This is important because Daphia from anadromous lakes experience an environment that is, on average, colder than Daphnia from the other lake types and may thus experience similar temperature-mediated selection.…”

Interpopulation variation in a fish predator drives evolutionary divergence in prey in lakes

Ecological factors are known to cause evolutionary diversification. Recent work has shown that evolution in strongly interacting predator species has reciprocal impacts on ecosystems. These divergent impacts of predators may alter the selective landscape and cause the evolution of prey. Yet, this link between intraspecific variation and evolution is unexplored. We compared the life history of a species of zooplankton (Daphnia ambigua) from lakes in New England in which the dominant planktivorous predator, the alewife (Alosa pseudoharengus), differs in feeding traits and migratory behaviour. Anadromous alewife (seasonal migrants) exhibit larger gapes, gill-raker spacing and target larger prey than landlocked alewife (yearround freshwater resident). In 'anadromous' lakes, Daphnia are abundant in the spring but extirpated by alewife predation in summer. Daphnia are rare year-round in 'landlocked' lakes. We show that Daphnia from lakes with anadromous alewife grew faster, matured earlier but at the same size and produced more offspring than Daphnia from lakes with landlocked or no alewife across multiple temperature and resource treatments. Our results are inconsistent with a response to size-selective predation but are better explained as an adaptation to colder temperatures and shorter periods of development (countergradient variation) mediated by seasonal alewife predation.

“…More specifically, in an evolutionary metacommunity context (Urban et al 2008), evolu-tionary change may increase the importance of local dynamics and reduce the impact of regional dynamics. Results of a recent experiment with the water flea Daphnia indeed suggest that evolutionary adaptation may result in a reduced regional impact in the context of climate change (Van Doorslaer et al 2009a).…”

There are an increasing number of studies documenting effects of global warming on the distribution and ecology of a wide variety of organisms. However, much less is known about evolutionary responses in species to increasing temperature. As a result, thermal microevolution is often ignored when making predictions about the impact of global warming on the distribution of organisms and the composition of communities. We investigated the ability of 2 large-bodied Daphnia species, D. magna and D. pulex, to genetically respond to increased temperature under semi-natural conditions. Daphnia populations were exposed for 6 mo to different temperature treatments in large outdoor mesocosms that simulated small pond systems. The selection experiment was followed by a common garden experiment in which we quantified thermal microevolution in important life history traits. Intrinsic growth rate did not respond to thermal selection. Instead, we observed an effect of selection temperature on size at maturity, indicating that Daphnia may genetically adapt to increased temperature within one growing season. In a previous laboratory study on thermal microevolution using single-species cultures of D. magna, we documented the opposite pattern with thermal microevolution in intrinsic growth rate but not in size at maturity. These observations suggest that the ecological context (semi-natural conditions compared to single species cultures) is very important in determining with which traits species adapt to global warming.

“…Rapid adaptation to climate-related variables has been documented in a few single-species systems [3][4][5][6][7], but because virtually all organisms experience regular interspecific interactions [8], understanding how biotic interactions affect evolutionary responses is critical.…”

As climate regimes shift in many ecosystems worldwide, evolution may be a critical process allowing persistence in rapidly changing environments. Organisms regularly interact with other species, yet whether climate-mediated evolution can occur in the context of species interactions is not well understood. We tested whether a species interaction could modify evolutionary responses to temperature. We demonstrate that predation pressure by Dipteran larvae (Chaoborus americanus) modified the evolutionary response of a freshwater crustacean (Daphnia pulex) to its thermal environment over approximately seven generations in laboratory conditions. Daphnia kept at 218C evolved higher population growth rates than those kept at 188C, but only in those populations that were also reared with predators. Furthermore, predator-mediated selection resulted in the evolution of elevated Daphnia thermal plasticity. This laboratory natural selection experiment demonstrates that biotic interactions can modify evolutionary adaptation to temperature. Understanding the interplay between multiple selective forces can improve predictions of ecological and evolutionary responses of organisms to rapid environmental change.
