Ecological coupling by material exchanges or dispersal between spatially distinct communities has important impacts on ecological processes, such as diversity stability relationships, ecosystem function, and food web dynamics. One important mode of coupling between ecosystems occurs via organisms with complex life histories, which often switch between distinct ecosystems during their life cycle...

Abstract Both non-rooted submerged vegetation dominated by coontail ( Ceratophyllum demersum) and floating duckweed Lemna gibba ) can maintain their stable dominance in small ponds channels. We examined the competitive interactions between them how sustain its state against plants a range of nutrient concentrations. Coontail were co-cultured static semi-static microcosm experiments, impact on n...

Bintang Alam is housing area in Karawang regency which often occurs flood. has a land of 147,33 ha and located on the edge Citarum River downstream section. Therefore, it necessary to have good implementation planning for drainage system housing. The research aimed find an effective way prevent solve floods Alam. There are 2 scenarios that applied at estate. Scenario 1, direct runoff from going...

Farm ponds in Yunlin County first appeared in 1,622 and have played roles in habitation, production, the ecology, culture, and disaster reduction. Farm ponds largely disappeared with the development of urban areas and the industrial sector; thus, effective preservation of the remaining ponds is critical. The criteria to evaluate the preservation value of farm ponds is established by expert ques...

The use of spawning sites by Bombina variegata was analysed in a dynamic habitat containing a variety of different ponds. Cool or shadowy as well as permanent ponds were not used for spawning at all. Among the ephemeral ponds that were used, egg numbers increased with water temperature, both when compared among ponds and between different areas within ponds. Egg numbers were also higher in pond...

A one year study was carried out in a waste stabilization ponds system where septage and sewage are cotreated. The system consists of two septage ponds which operate alternately followed by two ponds in series which receive the combined effluent. The septage ponds also act as evaporation ponds for the accumulated sludge. The monitoring program was divided in two phases. The results of the first...

The abundance and diversity of bacteria in two types of ponds were investigated by quantitative PCR and Illumina MiSeq sequencing. The results revealed that the abundance of bacterial 16S rRNA genes in D ponds (with grass carp fed sudan grass) was significantly lower than that in E ponds (with grass carp fed commercial feed). The microbial communities were dominated by Proteobacteria, Cyanobact...

Thawing permafrost in the Canadian Arctic tundra leads to peat erosion and slumping in narrow and shallow runnel ponds that surround more commonly studied polygonal ponds. Here we compared the methane production between runnel and polygonal ponds using stable isotope ratios, ¹⁴C signatures, and investigated potential methanogenic communities through high-throughput sequencing archaeal 16S rRNA ...
