Distribution and Attachment Characteristics of Sida Crystallina (O.F
Choi et al. Journal of Ecology and Environment (2016) 40:7 Journal of Ecology DOI 10.1186/s41610-016-0006-z and Environment RESEARCH Open Access Distribution and attachment characteristics of Sida crystallina (O.F. Müller, 1776) in lentic freshwater ecosystems of South Korea Jong-Yun Choi1*, Kwang-Seuk Jeong2,3, Seong-Ki Kim4, Se-Hwan Son1 and Gea-Jae Joo2 Abstract Background: Macrophytes are commonly utilised as habitat by epiphytic species; thus, complex macrophyte structures can support high diversities and abundances of epiphytic species. We tested the hypothesis that the presence of aquatic macrophytes is an important factor determining Sida crystallina (O.F. Müller, 1776) distribution. Results: An ecological survey was conducted in 147 lentic freshwater bodies. S. crystallina was frequently observed, and its density was strongly associated with macrophyte abundance. S. crystallina was found on emergent plant species such as Phragmites australis and Paspalum distichum, attached to the stem surfaces by adhesive substances secreted by the nuchal organ. Thus, S. crystallina was more strongly attached to macrophytes than to other epiphytic cladoceran species. We found higher densities of S. crystallina in filtered water with increased macrophyte shaking effort (i.e. 10, 20, 40, or 80 times). S. crystallina attachment was not related to fish predation. Stable isotope analysis showed that S. crystallina utilises epiphytic organic matter (EOM) on macrophytes as a food source. Conclusions: Consequently, S. crystallina seems to have a strong association with species-specific macrophyte biomass than with other cladoceran species, which may contribute to this species’ predominance in various freshwater ecosystems where macrophytes are abundant. -
Hull Fouling Is a Risk Factor for Intercontinental Species Exchange in Aquatic Ecosystems

Ballast water discharged from transoceanic ships is commonly believed to be the dominant pathway for species introduction and is therefore increasingly subject to domestic and international regulation. However, compared to species introductions from ballast, translocation by biofouling of ships’ exposed surfaces has been poorly quantified. We report translocation of species by a transoceanic bulk carrier intercepted in the North American Great Lakes in fall 2001. We collected 944 individuals of at least 74 distinct freshwater and marine taxa. Eight of 29 taxa identified to species have never been observed in the Great Lakes. Employing five different statistical techniques, we estimated that the biofouling community of this ship comprised from 100 to 200 species. These findings adjust upward by an order of magnitude the number of species collected from a single ship. -

Pandit Aquatic Ecology Laboratory, Centre of Research for Development, University of Kashmir 190006, J&K (India) Abstract: The present study was carried out on Wular lake, the largest freshwater lake of India to obtain a baseline data on the dynamics of species composition and density of cladoceran zooplankton for the period of one year from September 2010 to August 2011 at five different study sites. Investigations revealed about 23 species of Cladocera belonging to six families were reported during the entire study. Among the six families, Chydoridae was numerically dominant, being represented by nine species, followed by Daphnidae with seven species, Bosminidae, Moinidae and Sididae with two species each and Macrothricidae with only one species. Shannon index was noticed highest for site III reflecting the stable environmental conditions of this biotope.

Genetic Population Structure of the Fairy Shrimp Branchinecta Coloradensis (Anostraca) in the Rocky Mountains of Colorado
Color profile: Disabled Composite Default screen 2049 Genetic population structure of the fairy shrimp Branchinecta coloradensis (Anostraca) in the Rocky Mountains of Colorado Andrew J. Bohonak Abstract: Dispersal rates for freshwater invertebrates are often inferred from population genetic data. Although genetic approaches can indicate the amount of isolation in natural populations, departures from an equilibrium between drift and gene flow often lead to biased gene flow estimates. I investigated the genetic population structure of the pond- dwelling fairy shrimp Branchinecta coloradensis in the Rocky Mountains of Colorado, U.S.A., using allozymes. Glaciation in this area and the availability of direct dispersal estimates from previous work permit inferences regarding the relative impacts of history and contemporary gene flow on population structure. Hierarchical F statistics were used θ θ to quantify differentiation within and between valleys ( SV and VT, respectively). Between valleys separated by 5– θ 10 km, a high degree of differentiation ( VT = 0.77) corresponds to biologically reasonable gene flow estimates of 0.07 individuals per generation, although it is possible that this value represents founder effects and nonequilibrium ≤ θ conditions. On a local scale ( 110 m), populations are genetically similar ( SV = 0.13) and gene flow is estimated to be 1.7 individuals exchanged between ponds each generation. This is very close to an ecological estimate of dispersal for B. coloradensis via salamanders. Gene flow estimates from previous studies on other Anostraca are also similar on comparable geographic scales. Thus, population structure in B. coloradensis appears to be at or near equilibrium on a local scale, and possibly on a regional scale as well. -
