Phytoplankton and Ecological Status of the Lakes of the Forest Area in the Omsk Priirtyshye

GIS-based approach to find the suitable sites for surface flow constructed wetlands was employed for the Lithuanian river basins with low ecological status. According to the nature of the analysed criteria the flowchart consists of two phases. Criteria used include hydrographical network, soil properties, terrain features, land use, etc. Some of them have strictly defined values (constraints), and other ranges within certain limits (factors). Limited criteria were analysed using rejection principle and influencing factors using proximity analysis and overlay methods. Selecting the potential sites using standard GIS analysis tools there was estimated about 3286 sites for possible wetlands with the mean area of inflow basin about 4 km2 in the basins of water bodies at risk.

The internationally renowned Muong Phang Cultural and Historical Site is located in the Dien Bien Phu region, northwestern Vietnam, and has received special attention from the public because of its great biodiversity. This site has a large forest area and other habitats including lakes, streams, rivers and paddyfield. These habitats would be ideal homes for bats and other biological taxa. However, in general, the wildlife of the Muong Phang Cultural and Historical Site receives little attention from scientists and authorities. Between 2014 and 2016, we conducted series of surveys for bats in Muong Phang. Bat capture and sound recordings were the main procedure to obtain materials and data necessary for the assessment of diversity and conservation status. The results of the surveys this time revealed that there are 19 species of bats belonging to 7 genera, 5 families in the study area. Of these, a Myotis sp. is different from all the previously recorded Myotis bats from Vietnam, and, a Rhinolophus sp. is different from every described species of the family Rhinolophidae. This paper provides the first records of bats from Muong Phang with remarks on their taxonomy and conservation status. Citation: Dao Nhan Loi, Vu Dinh Thong, 2017.

Terrestrial Biodiversity

With the exponential rise of human activities in the past decades, majority of studies conducted in Taal Volcano Protected Landscape (TVPL) are geared towards the conservation and preservation of Lake Taal’s remaining biodiversity. However, the current structure and assemblage of its terrestrial biotic communities remain relatively unstudied. In this study, we conducted biodiversity censuses in the four sites in TVPL to provide baseline information regarding the community structure of the selected study sites. Comparison of the plant diversity in Taal Volcano Crater Island and Romandan Falls within the forested areas of Mataas na Kahoy, Batangas reveal that both sites support remarkably different vegetation, with the former supporting a smaller floral diversity. The fairly small number of animal samples present difficulty in providing conclusive findings to the wildlife structure of the two study sites. However, the presence of 11 animal species exhibit valuable results in determining the ecological status of TVPL. It is deduced that several ecological barriers exist between the sites, which is attributed to their unique terrestrial biota.
