Special Issue Information

Dear Colleagues,

Global warming and abnormal climate caused by the emission of many greenhouse gases are the most serious environmental problems facing the earth today. This phenomenon is occurring in various natural ecosystems, including lakes, rivers, and estuaries, as well as human activity spaces. In particular, it is more evident in the species abundance and diversity of aquatic communities, such as bacteria, aquatic insects, diatoms, aquatic plants, and fish that inhabit river ecosystems. This Special Issue covers the accumulation of long-term and short-term aquatic environment and biomonitoring data on changes in aquatic ecosystems caused by climate change, as well as advanced statistical analysis and future predictions based on them. In particular, this Special Issue is open to taxonomy, embryology, molecular biology, and hydraulic-model ecologists on aquatic environments and aquatic organisms, such as rivers, lakes and estuaries.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The Yeongsan River estuary was divided into freshwater and seawater zones by a sea dike constructed at its mouth in 1981. The freshwater zone, which flows through a metropolitan area, is eutrophic, causing frequent algal blooms with an expected increase in the concentration of refractory organic compounds such as humic substances (HS). Herein, the in situ freshwater zone phytoplankton community size and taxonomic composition were investigated in response to the addition of humic acids (HA) using seasonal mesocosm experiments. Phytoplankton (chlorophyll a) were fractionated into nano-(<20 µm) and net-size (>20 µm) classes and identified by species or genus. Their response to HA treatment was examined by repeated measures analysis of variance (RM-ANOVA). With the addition of HA, the concentrations of total and nanosized chlorophyll a increased significantly (p < 0.05), whereas that of net-sized chlorophyll a did not change significantly through the seasons. The abundance of Stephanodiscus sp. (diatoms) also increased significantly when this genus dominated the phytoplankton community. This suggests that the management of HS may be crucial in mitigating algal blooms in estuaries, such as in the Yeongsan River estuary, that are subjected to anthropogenic disturbances by engineered structures.
