After aquatic systems are recovered, animals hatch from resting eggs and help re-establish active communities. However, although the ability of resting eggs to survive desiccation is largely known, it is unclear to what extent the duration of desiccation affects the viability and hatching patterns of resting eggs. In this study, we assessed the viability of resting egg banks in naturally wet and dry sediments through ex-situ hatching experiments. In addition, we simulated dry out episodes of different durations (2 and 8 months) in wet sediments originating from temporary systems. We observed hatchlings of rotifers, cladocerans, copepods, ostracods, and anostracans in wet and dry sediments. Drying the sediments for different durations did not change the species richness and composition of hatchlings, possibly because temporary systems select for species and genotypes that are more prone to producing resting eggs, which survive desiccation. However, some species were stimulated to hatch after desiccation, suggesting that desiccation might help break the dormancy of resting eggs from temporary systems. Desiccation intervals up to 8 months likely do not affect the viability of resting eggs from temporary systems. Since many lakes are about to experience unpredictable droughts owing to human activities and ongoing global changes, the ability of resting eggs to tolerate desiccation will play a key role in zooplankton community recovery.</p>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"104 1-2","pages":"26-33"},"PeriodicalIF":1.9,"publicationDate":"2019-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/iroh.201801977","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41523660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graça,&nbsp;Verónica Ferreira","doi":"10.1002/iroh.201801965","DOIUrl":"10.1002/iroh.201801965","url":null,"abstract":"The metabolism of forest streams depends on the decomposition of plant litter of terrestrial origin. In turn, the rate at which litter decomposes depends on litter characteristics, decomposer activity, environmental characteristics, and their interactions. Atmospheric changes, such as increases in atmospheric carbon dioxide concentration ([CO 2 ]) and in temperature, may affect all these variables. Here, we report the results of a meta ‐ analysis of 41 studies conducted worldwide between 1993 and 2017 on the effects of elevated atmospheric [CO 2 ], elevated temperature, or both (temperature + [CO 2 ]) on litter decomposition in streams. Elevated temperature significantly increased litter decomposition rates, whereas elevated [CO 2 ] and temperature + [CO 2 ] did not significantly affect litter decomposition rates. The effect of elevated temperature did not depend on the type of study (i.e., laboratory or field study, correlative field or manipulative field study) but in correlative field studies, the temperature effect was stronger over latitudinal than altitudinal gradients. Effects of elevated temperature also did not depend on the type of decomposer community (microbial or microbial and macroinvertebrates) but effects were always significant for total litter decomposition (both microbes and macroinvertebrates involved), whereas microbial ‐ driven litter decomposition was significantly affected only in manipulative studies. Effects of elevated temperature did not depend on the litter identity, although significant effects were found for some litter genera but not others. In terrestrial ecosystems, the elevated temperature was found to increase litter decomposition rates, whereas elevated [CO 2 ] decreased litter decomposition rates. Study type (laboratory or field) and litter identity were important moderators of the response of litter decomposition to elevated temperature and [CO 2 ] in terrestrial ecosystems. These differences between soil and stream ecosystems may be partially due to intrinsic differences (such as moisture that is not limiting in streams) between these ecosystems. In addition, our meta ‐ analysis is geographically biased with most studies being conducted in Europe. More studies in other parts of the world could allow for a better understanding of the effects of climate warming and [CO 2 ] increases on litter decomposition, the global carbon cycle, and biochemistry in streams.","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"104 1-2","pages":"14-25"},"PeriodicalIF":1.9,"publicationDate":"2019-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/iroh.201801965","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47891843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Is the absence of <i>Artemia</i> in some Crimean lakes determined by the presence of predators or by salinity? To answer this question field long-term and experimental data collected in the Crimean lakes were used. With the least probability, the populations of <i>Artemia</i> existed in the lakes with a salinity of up to 50 g/L or above 300 g/L. Self-reproducing <i>Artemia</i> populations (all age stages) were most likely (≥80% of occurrence) noted in the salinity range of 150–200 g/L. Long-term monitoring in two lakes showed that in different years, a significant negative correlation of <i>Artemia</i> abundance with the numbers of amphipod <i>Gammarus aequicauda</i> and ostracod <i>Eucypris mareotica</i> was found in both lakes. This correlation can be explained by ostracod and amphipod predation on <i>Artemia</i>. In years without predator populations, the number of <i>Artemia</i> was higher by several times.

The taxonomic and functional macroinvertebrate community composition significantly differed between outer margin, center, and shore locations. At shore locations, higher proportions of Gastropoda, Hydrachnidia and Coleoptera, mobile swimmers/skaters, predators, and shredders were found. However, outer margin locations were characterized by a higher proportion of sessile filter-feeding Bivalvia and mining Diptera. At the outer margins, also greater contributions of taxa preferring pelal habitats and r-strategists typical for more disturbed environments were observed. An indicator species analysis revealed <i>Asellus aquaticus</i> (Crustacea) and Scirtidae Gen sp.
