“…Colonization by a new Daphnia species or changes in the genetic composition of native Daphnia populations during the course of eutrophication have been shown in several studies conducted using sediment cores (Hairston et al 1999;Jankowski and Straile 2003;Brede et al 2009). Daphnia galeata invaded the formerly oligotrophic to mesotrophic Lakes Constance and Greifensee in the period of eutrophication and produced hybrids with the native Daphnia longispina population (Jankowski and Straile 2003;Brede et al 2009).…”

“…Because ephippia and other cladoceran remains sink to the lake bottom, sediment cores are a useful source of information for the investigation of past Daphnia populations (Korhola and Rautio 2001). Since the diapausing eggs can stay viable for several decades or longer, genetic analysis of the egg banks can be performed either on the hatchlings (Weider et al 1997;Hairston et al 1999;Jankowski and Straile 2003) or directly on the diapausing eggs (Duffy et al 2000;Brede et al 2009). Moreover, ephippia are important for dispersal and colonization of Daphnia into new habitats (Havel and Shurin 2004).…”

It has been proposed that anthropogenic eutrophication of lakes facilitated the establishment of populations of the cladoceran Daphnia galeata into the originally oligotrophic lakes north of the European Alps in the 1960s. This hypothesis lacks the support of studies on unproductive lakes, in which the past eutrophication is assumed to have never been on the level necessary for D. galeata to reach high abundances and to establish permanently. In order to investigate if such species shifts also happened in unproductive systems, we studied the past and present taxonomic composition of three ultra-oligotrophic Swiss lakes that were only marginally affected by eutrophication using molecular methods on diapausing eggs sampled from sediment cores. D. galeata temporarily established in unproductive lakes, but its colonization success seemed to depend on the general trophic state of the lake and the magnitude of eutrophication. In two of the studied lakes, D. galeata could establish a significant population size, whereas it was not successful in the most unproductive lake with the weakest eutrophication. Even in unproductive lakes, eutrophication led to partly irreversible species changes, providing evidence that this anthropogenic disturbance is responsible for species shifts in many pre-alpine lakes in Central Europe.

“…D. pulex is no longer present in the extant zooplankton fauna of the Belauer See. Environmental changes in a water body may influence invasion and extinction of Daphnia species (Hairston et al 1999b;Duffy et al 2000;Reid et al 2000). If one assumes that these resting eggs of D. pulex did not drift into the sediments from outside the basin, but reflect autochthonous production in the water column of the Belauer See in the past, this may serve as a tool for examining the effect of changing environments not only on populations, but also on communities.…”

‘Ancient’ DNA in the resting egg bank of a microcrustacean can serve as a palaeolimnological database

Recent work on the diapausing egg banks of zooplankton, such as Daphnia (Crustacea: Anomopoda), indicates that these eggs can remain viable for decades while, theoretically, DNA can remain intact for even longer periods (i.e. centuries or millennia). We isolated diapausing eggs of Daphnia from a 30 m long sediment core taken from a hypereutrophic, northern German lake (Belauer See), with some eggs found in dated core material as old as 4500 years. Using microsatellite markers, we analysed the genetic structure of the resting eggs dated as old as ca. 200 years, and found that, although levels of heterozygosity remained remarkably stable, significant genetic differentiation (Nei's D = 0.36; F ST = 0.15) between recent and 'ancient' resting eggs (including allele frequency shifts and private alleles) was detected. These shifts represent either species-level changes in this complex (i.e. species-specific characters of ephippia are not always robust), or intraspecific shifts in genetic variation, or a combination of both. This study demonstrates that the egg banks of aquatic zooplankton can serve as repositories of both genetic (intrapopulational) and ecological (interspecific) information. The use of molecular markers, such as microsatellites, on diapausing egg/seed banks may open new avenues of enquiry related to tracking the long-term genetic (and/or species) shifts that are associated with long-term environmental changes.

“…this strain was collected from one of the canals of Xochimilco close to the collection site of H. incongruens which was used in this test. Studies on zooplankton suggest that populations develop tolerance to toxicity (Hairston et al, 1999;Gustafsson and Hansson, 2004;Sarnelle and Wilson, 2005;Sarnelle et al, 2010) and/or adaptations in ingesting cyanobacteria (i.e. iyer and Rao, 1998), if they face constant exposure to these diets.…”

Demographic responses of Heterocypris incongruens (Ostracoda) related to stress factors of competition, predation and food

2016

Heterocypris incongruens is a widely distributed ostracod which can maintain its populations under stressful conditions such as those in temporary ponds and under low-quality diets, for example, detritus. It often co-occurs with cladocerans and fish living in shallow water bodies. Nevertheless, little is known about its response to the presence of predators, its consumption capacity of cyanobacteria typically present in eutrophic systems, and its interaction with other species in similar habits. We studied here the demographic responses of H. incongruens fed the green alga Scenedesmus acutus, two strains of Microcystis cf. aeruginosa and Limnothrix sp. Experiments were conducted separately and together in the presence of the cladoceran Simocephalus vetulus and the cichlid ﬁsh, Oreochromis kairomones. The ostracod maintained growth in all treatments, the reproductive output decreased on dietary Limnothrix sp., and its life expectancy was significantly lower with the toxic strain of Microcystis. The coexistence of both crustacean species increased the rate of population growth (~ 0.33 day-1) of S. vetulus and life expectancy (36-44 days) of H. incongruens on the test diets compared with controls (23-33 days). Our study suggests facilitation affects the interaction between the two microcrustaceans, especially on poor quality cyanobacterial diets.
