FLOODPLAIN RIVER FOOD WEBS IN THE LOWER MEKONG BASIN A Dissertation by CHOULY OU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kirk O. Winemiller Committee Members, Masami Fujiwara Thomas D. Olszewski Daniel L. Roelke Head of Department, Michael Masser December 2013 Major Subject: Wildlife and Fisheries Sciences Copyright 2013 Chouly Ou ABSTRACT The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened by major hydropower development and over-exploitation. Knowledge of river food web ecology is essential for management of the impacts created by anthropogenic activities on plant and animal populations and ecosystems. In the present study, I surveyed four tropical rivers in Cambodia within the Mekong River Basin. I examined the basal production sources supporting fish biomass in the four rivers during the dry and wet seasons and explored the relationship between trophic position and body size of fish at various taxonomic levels, among local species assemblages, and across trophic guilds. I used stable isotopes of carbon and nitrogen to estimate fish trophic levels and the principal primary production sources supporting fishes. My study provides evidence that food web dynamics in tropical rivers undergo significant seasonal shifts and emphasizes that river food webs are altered by dams and flow regulation. Seston and benthic algae were the most important production sources supporting fish biomass during the dry season, and riparian macrophytes appeared to be the most important production source supporting fishes during the wet season. -

The present study was undertaken in order to untangle some of the problems of classification which have beset this group. The genera have not been studied in toto since the days of Bleeker and Gunther. In this study I have made an attempt to clarify the relationships of the various genera, which in some cases has involved revision of generic limits. Lack of time and material has precluded a thorough analysis of the species within any genus; for the same reason no skeletal examinations were possible. It is hoped, however, that a clarification of generic limits through study of external characters will make it easier in the future for interested workers, with sufficient material at hand, to do further and much-needed work on both the genera and the species.

Ratanakiri, Cambodia*
Southeast Asian Studies, Vol. 47, No. 3, December 2009 Understanding Changes in Land and Forest Resource Management Systems: Ratanakiri, Cambodia* Jefferson FOX,** John B. VOGLER*** and Mark POFFENBERGER**** Abstract This paper draws on case studies from three communities in Ratanakiri to illustrate both the forces driving land-use and tenure change as well as how effective community stewardship can guide agricultural transi- tions. The study combines a time series of remotely sensed data from 1989 to 2006 to evaluate changes in land use, and relates this data to in-depth ground truth observations and social research from three villages. The methodology was designed to evaluate how indigenous communities who had historically managed forest lands as communal resources, are responding to market forces and pressures from land speculators. Krala Village received support from local non-government organizations (NGOs) to strengthen community, map its land, demarcate boundaries, strengthen resource use regulations, and develop land-use plans. The two other villages, Leu Khun and Tuy, each received successively less support from outside organizations for purposes of resource mapping and virtually no support for institutional strengthening. The remote sensing data indicates that in Krala, over the 16 year study period, protected forest areas remained virtually intact, while total forest cover declined at an annual rate of only 0.86% whereas in Leu Khun and Tuy the annual rates were 1.63 and 4.88% respectively. Keywords: land use, land cover, forest management, resource management systems, Cambodia I Introduction Over the past decade, Ratanakiri Province has experienced unprecedented changes in land use and tenure. This study analyzes remotely sensed images taken in 1989 and December 2006 to assess changes in vegetative cover in three areas near Banlung the provincial capital, and draws on in-depth case studies from three communities in the research area. -

Employing Geographical Information Systems in Fisheries Management in the Mekong River: a Case Study of Lao PDR
Employing Geographical Information Systems in Fisheries Management in the Mekong River: a case study of Lao PDR Kaviphone Phouthavongs A thesis submitted in partial fulfilment of the requirement for the Degree of Master of Science School of Geosciences University of Sydney June 2006 ABSTRACT The objective of this research is to employ Geographical Information Systems to fisheries management in the Mekong River Basin. The study uses artisanal fisheries practices in Khong district, Champasack province Lao PDR as a case study. The research focuses on integrating indigenous and scientific knowledge in fisheries management; how local communities use indigenous knowledge to access and manage their fish conservation zones; and the contribution of scientific knowledge to fishery co-management practices at village level. Specific attention is paid to how GIS can aid the integration of these two knowledge systems into a sustainable management system for fisheries resources. Fieldwork was conducted in three villages in the Khong district, Champasack province and Catch per Unit of Effort / hydro-acoustic data collected by the Living Aquatic Resources Research Centre was used to analyse and look at the differences and/or similarities between indigenous and scientific knowledge which can supplement each other and be used for small scale fisheries management. The results show that GIS has the potential not only for data storage and visualisation, but also as a tool to combine scientific and indigenous knowledge in digital maps. Integrating indigenous knowledge into a GIS framework can strengthen indigenous knowledge, from un processed data to information that scientists and decision-makers can easily access and use as a supplement to scientific knowledge in aquatic resource decision-making and planning across different levels. -
