“…Lakes within this sample are typically small and humic. Globally, however, small lakes dominate: one third of the total world lake surface area consists of lakes that are smaller than 0.1 km 2 , and the estimated global average of lake size is 0.012 km 2 (Downing et al, 2006). All of the lakes in our study were 0.04 km 2 or larger, and consequently median lake area in the current study, 0.28 km 2 , is larger than the estimate of average global lake area.…”

“…Particularly small lakes in the areas of thawing permafrost form significant spot sources of atmospheric CH 4 (Hamilton et al, 1994;Walter et al, 2007). The new estimates of number and area of global lakes emphasized the high number of small lakes in the boreal and arctic regions (Downing et al, 2006). These small water bodies are susceptible to ongoing changes in climate and land use, which may notably alter the lake environment and their CH 4 fluxes.…”

Abstract. This study explores the variability in concentrations of dissolved CH 4 and annual flux estimates in the pelagic zone in a statistically defined sample of 207 lakes in Finland. The lakes were situated in the boreal zone, in an area where the mean annual air temperature ranges from −2.8 to 5.9 • C. We examined how lake CH 4 dynamics related to regional lake types assessed according to the EU water framework directive. Ten lake types were defined on the basis of water chemistry, color, and size. Lakes were sampled for dissolved CH 4 concentrations four times per year, at four different depths at the deepest point of each lake. We found that CH 4 concentrations and fluxes to the atmosphere tended to be high in nutrient rich calcareous lakes, and that the shallow lakes had the greatest surface water concentrations. Methane concentration in the hypolimnion was related to oxygen and nutrient concentrations, and to lake depth or lake area. The surface water CH 4 concentration was related to the depth or area of lake. Methane concentration close to the bottom can be viewed as proxy of lake status in terms of frequency of anoxia and nutrient levels. The mean pelagic CH 4 release from randomly selected lakes was 49 mmol m −2 a −1 . The sum CH 4 flux (storage and diffusion) correlated with lake depth, area and nutrient content, and CH 4 release was greatest from the shallow nutrient rich and humic lakes. Our results support earlier lake studies regarding the regulating factors and also the magnitude of global emission estimate. These results propose that in boCorrespondence to: S. Juutinen (sjuutine@mtholyoke.edu) real region small lakes have higher CH 4 fluxes per unit area than larger lakes, and that the small lakes have a disproportionate significance regarding to the CH 4 release.

“…It can be concluded that riparian zones may also provide a hiding place for many fishes which prey on zooplankton. On the other hand, Dodson et al [38], and Xu et al [39] showed a high positive influence of riparian zones on the abundance and biodiversity of lake zooplankton. Hence, the precise causes of the greater abundance of zooplankton in rivers with vegetation-free riparian zone are difficult to explain, especially because the standard deviation of the abundance of each group of zooplankton was relatively high.…”

Abstract:The abundance and the biodiversity of summer zooplankton in the waters of the Drawa drainage (NW Poland) were studied, as was their relation to selected environmental conditions. The conditions upstream, especially in the outlets of lakes, did not affect the zooplankton communities downstream. This was also true of tributaries which had no influence on the shape of the zooplankton communities in the main river. The number of zooplankton in the outlets of eutrophic lakes was greater than in those of mesotrophic lakes. Increased vegetation cover significantly affected mainly the crustacean communities of zooplankton. Larger amounts of zooplankton were observed in rivers where the riparian zone was not covered with vegetation, but this difference was not significant. The hydrological conditions of the rivers and the Secchi depth visibility strongly impacted the composition of the zooplankton. The influence of abiotic factors was most pronounced on the abundance of cladocerans, and least pronounced on the abundance of rotifers.

“…For example, stocking of filter-feeding bighead carp is often planned based on the distribution data of crustacean zooplankton (Guo et al, 2015). The factors taken into account were mainly water chemistry, macrophytes and eutrophication (Alexander and Hotchkiss, 2010;Dodson et al, 2005). However, the spatial distribution of crustacean zooplankton is not always related to single environmental factor, and have seemingly contradictory distribution patterns in different water bodies (Hulot et al, 2000).…”

It has been reported that community structure of crustacean zooplankton is related to environment factors and abundance of predacious fishes. Most studies, however were based on observation on independent water bodies, which may complicate the results with uninterested factors. A large river-connected lake has partitioned regions with the characteristics of either a river or a lake albeit allowing exchanging of zooplankton of different regions. Thus, a river-connected lake is an ideal system for studying distribution of crustacean zooplankton and investigating its affecting factors. In this study, 11 stations of a large river-connected lake, Lake Gaoyou, were sampled in all four seasons. Taxonomic diversity and species abundance were recorded and their correlation with environmental factors was investigated. A total of 26 and 22 species of crustacean zooplankton were recorded in the river and lake region, respectively. The abundance of crustacean in the river region was significantly higher than that in the lake region. The relative abundance of calanoids and Bosmina fatalis in the river region was lower than that in the lake region, whereas the abundance of cyclopoids and other cladocera species was lower in the lake region than in the river region. Cluster analysis showed that crustacean assemblages could be divided into two, one cluster grouping all sites from the river region, and the other cluster included all sites in the lake region. According to Pearson correlation and canonical correspondence analysis, the distribution of crustacean was positively correlated with water temperature and chlorophyll a gradient. Chlorophyll a and fish abundance are excellent predictors on spatial distribution of crustacean zooplankton in Lake Gaoyou. Our findings may also help in planning of bighead carp stocking in Lake Gaoyou.
