“…Crustaceans are widely used as sentinel species in various aquatic systems (Rinderhagen et al 2000; Peschke et al 2014; Chaumot et al 2015). Gammarids are currently used in ecotoxicology because of their sensitivity to contaminants (Kunz et al 2010).…”

Active biomonitoring approaches are now recognized as relevant for monitoring water contamination and toxicity. Nevertheless, due to the confounding influence of variable and uncontrolled environmental conditions such as temperature, biological markers measured on transplanted individuals to assess water quality are difficult to interpret. The purpose of the present study is to propose a methodology for adapting a laboratory test of chronic sublethal toxicity based on the molting cycle of Gammarus fossarum to in situ assays. To this end, we 1) adapted the molt cycle temperature‐dependent model developed in Part 1 (Chaumot et al. 2020, this issue) to the fluctuating temperatures measured in the field; 2) assessed the predictive power of our approach as a “reference value” from gammarids caged in 9 nonimpacted sites at different seasons; and 3) tested the relevance of our tool to interpret in situ reproductive bioassays from 5 upstream/downstream studies and a large‐scale deployment in 12 sites. Our approach based on modeling the progress of gammarid molting cycle as a function of temperature appeared to be a relevant and robust tool for interpreting in situ observations in different environmental contexts in time and space. By avoiding using a “reference” or upstream situation as a baseline from which water quality could be assessed, this approach provides a real added value to water quality diagnosis in biomonitoring programs.

“…Crustacean gammarids are a major constituent of animal communities inhabiting European freshwater lotic ecosystems. They are increasingly used as bioindicators in environmental monitoring [25]. Metallic and especially cadmium (Cd) contaminations have been documented as a limiting factor of gammarid abundance in French watercourses [26,27].…”

We explore the delayed consequences of parental exposure to environmentally relevant cadmium concentrations on the life-history traits throughout generations of the freshwater crustacean Gammarus fossarum. We report the preliminary results obtained during a challenging one-year laboratory experiment in this environmental species and propose the use of population modeling to interpret the changes in offspring life-history traits regarding their potential demographic impacts. The main outcome of this first long-term transgenerational assay is that the exposure of spawners during a single gametogenesis cycle (3 weeks) could result in severe cascading effects on the life-history traits along three unexposed offspring generations (one year). Indeed, we observed a decrease in F1 reproductive success, an early onset of F2 offspring puberty with reduced investment in egg yolk reserves, and finally a decrease in the growth rate of F3 juveniles. However, the analysis of these major transgenerational effects by means of a Lefkovitch matrix population model revealed only weak demographic impacts. Population compensatory processes mitigating the demographic consequences of parental exposure seem to drive the modification of life-history traits in offspring generations. This exploratory study sheds light on the role of population mechanisms involved in the demographic regulation of the delayed effects of environmental toxicity in wild populations.

“…Charophytes are one of the most important habitat formers among macrovegetation in the soft-bottom areas in the Baltic Sea [18]. Gammarids are diverse group of amphipod crustaceans which has important role in herbivory, detritus cycle and as a prey for fish [19]. Seven species of charophytes have been found in the Estonian coastal waters [16].…”

The ongoing climate change is expected to affect the distribution and vitality of marine aquatic species through various links and changes in environmental conditions. The aim of the study was to analyse and compare climate change related effects on native and non-native benthic species groups in the Baltic Sea. We analysed the impact of changes on the charophytes (native Chara aspera and non-native Chara connivens) and gammarid amphipods (native Gammarus salinus and non-native Gammarus tigrinus). Currently, C. aspera and G. salinus are the most widespread and frequent species among charophytes and gammarids in NE Baltic Sea. C. connivens has been recorded in single locations in the 1960s, following the continuous enlargement of the distribution area since 2005. G. tigrinus has showed significant occupation success in the region since their first finding in 2003. The random forest modelling method was used to produce current species distribution models and to predict the potential changes of distribution based on future climate scenarios. In the brackish Baltic Sea, species are often living close to their salinity tolerance limits and the decrease in salinity will probably cause profound changes in distribution of both marine and freshwater species. Moreover, the model predictions showed that, probably due to wider salinity and temperature tolerance, the non-native species will gain advantages over native species. Due to climate change, a significant increase of the distribution areas of non-native species is expected to occur on account of the native species. The distribution area of C. connivens is predicted to double and G. tigrinus to increase by 15%. Changes in environmental conditions also favour the distribution of native charophyte C. aspera due to the freshwater origin of the species. However, the marine species G. salinus is predicted to lose 65% of its distribution area.
