The oriental river prawn (Macrobrachium nipponense) is mainly distributed in East Asia. The phylogeography, population genetic structure and historical demography of this species in the East Asia were examined by using partial sequences of the cytochrome oxidase subunit I (COI) and 16S rRNA in mitochondrial DNA. Ten populations that included 239 individuals were collected from Taiwan (Shihmen R...

Many aquatic plant species are distributed over large areas and diverse environments with populations interconnected by abiotic and biotic mediators. Here, we examined differences and similarities in the population genetic structure of six sympatric and widespread aquatic plant species. We sampled the aquatic species from six Chinese lakes found on plateaus, plains, and different river systems ...

Data was collected on Nov. 6, 2009 at the ARL Lake Travis Test Station. The lake has an estimated maximum depth of 37 m [2]. As seen in Fig. 1, the lake has a nearby dam and hilly former river bed terrain that contribute to high reverberation. Fig. 2 shows the temperature and sound speed profiles—a relatively constant set of temperatures and speeds compared to the thermoclines from the July, 20...

In previous years, studies h.;.ve been conducted on several tributaries of Otsego Lake and the upper Susquehanna River that analyzed the concentrations offecal coliforms. a group of bacteria found in the intestines ofwarm blooded animals and thus indic' ve offecal contamination. Research was conducted for the duration of the SUIll:.ler ,f 1996 on the upper Susquehanna River, Hayden Creek, Shado...

Aims of the Study: The physical, chemical and biological characteristics of Karaj River (near the city of Tehran, Iran), has been studied to evaluate the suitability of its water for domestic uses. Materials & Methods: Samples of water were collected from various localities before, in and after Karaj Dam Lake and were analyzed based on needs for Water Q...

Giant salvinia (Salvinia molesta Mitchell) is a nuisance, free-floating aquatic fern that can double biomass in 10 days through vegetative reproduction. Hydrilla (Hydrilla verticillata (L.f.) Royle) is a perennial submersed aquatic plant that can propagate from stem fragments, turions, and subterranean tubers representing a triple threat for management methods. Both plants disrupt water bodies ...
