“…Especially in poorly buffered waters, such levels could become much more common over the next decades. Similar levels of pCO 2 have been used in other studies that investigate the impact of global change associated elevated pCO 2 (Jeffrey et al 2018;Weiss et al 2018;Parra and Espinoza-Villalobos 2020). The control level of 700 ppm represents a commonly measured supersaturated scenario since concentrations in temperate lakes typically vary between 500 and 4000 ppm (Sobek and Tranvik 2005;Raymond et al 2013).…”

Increasing pCO 2 in freshwaters across the globe will likely be accompanied by acidification. Although this has been linked to reduced calcification, growth, and survival in several marine species, similar responses in freshwater organisms remain largely unexplored. Here, we investigated the direct effects of elevated pCO 2 and associated acidification on the water flea Daphnia magna. As a highly efficient filter feeder, this crustacean is a dominant primary consumer in freshwater zooplankton assemblages, capable of controlling algal growth. It has a high calcium content compared to other zooplankton species, which might make it particularly sensitive since calcification may be impaired under elevated pCO 2 . We exposed newly hatched individuals of four clonal lineages to 27,000 ppm pCO 2 corresponding to a pH of 6.7 in a controlled laboratory experiment. Both survival and calcium content were reduced and juveniles grew slower and matured later under elevated pCO 2 . Adult growth rate was not affected by pCO 2 suggesting that surviving adults are less sensitive or may acclimate over time but at the cost of reduced offspring size. We hypothesize that the combination of elevated pCO 2 and low pH interferes with the calcification process, reflected in slower growth, smaller body size and reduced calcification in D. magna. In turn, this might lead to less efficient control of phytoplankton as an ecosystem service and reduce their competitive advantage over other zooplankters with less calcified bodies.

Se muestran los primeros datos sobre la comunidad de ostrácodos en los humedales del sudeste de España (provincias de Jaén y Córdoba). Se han estudiado un total de 21 humedales, habiéndose registrado la presencia de 12 especies de ostrácodos, pertenecientes a 8 géneros diferentes. Los valores de singularidad muestran la importancia de los humedales temporales y salinos para esta comunidad biótica. Esta aportación pone en valor la necesidad de incrementar el conocimiento que se tiene sobre la distribución y ecología de las especies de ostrácodos en la Península Ibérica.
