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. -

This species was previously recorded from the same area over 15 years ago, but was considered extirpated. The rediscovery of a reproducing population of this species highlights the dearth of information available regarding the dozens of non-native fishes in Florida, as well as the need for additional research and monitoring. Key words: canal; croaking gourami; cypress swamp; Florida; Loxahatchee; Osphronemidae; Trichopsis vittata was previously considered extirpated (Shafland Introduction et al. 2008a, b), but is now known to be reproducing in a localised area. Dozens of non-native fishes have been introduced into Florida’s inland waterways, via accidental escape, pet releases, or intentional introduction -

Rivers in the Japanese archipelago, separated from the continent of Asia by about 17 Ma, have experienced an intermittent exchange of freshwater fish taxa through a narrow land bridge generated by lowered sea level. As the Korean Peninsula and Japanese archipelago were not covered by an ice sheet during glacial periods, phylogeographical analyses in this region can trace the history of biota that were, for a long time, beyond the last glacial maximum. In this study, we analyzed the phylogeography of four freshwater fish taxa, Hemibarbus longirostris, dark chub Nipponocypris temminckii, Tanakia ssp. and Carassius ssp., whose distributions include both the Korean Peninsula and Western Japan. We found for each taxon that a small component of diverse Korean clades of freshwater fishes Citation: Taniguchi, S.; Bertl, J.; migrated in waves into the Japanese archipelago to form the current phylogeographic structure of Futschik, A.; Kishino, H.; Okazaki, T. -

An Assessment of Exotic Species in the Tonle Sap Biosphere Reserve
AN ASSESSMENT OF EXOTIC SPECIES IN THE TONLE SAP BIOSPHERE RESERVE AND ASSOCIATED THREATS TO BIODIVERSITY A RESOURCE DOCUMENT FOR THE MANAGEMENT OF INVASIVE ALIEN SPECIES December 2006 Robert van Zalinge (compiler) This publication is a technical output of the UNDP/GEF-funded Tonle Sap Conservation Project Executive Summary Introduction This report is mainly a literature review. It attempts to put together all the available information from recent biological surveys, and environmental and resource use studies in the Tonle Sap Biosphere Reserve (TSBR) in order to assess the status of exotic species and report any information on their abundance, distribution and impact. For those exotic species found in the TSBR, it is examined whether they can be termed as being an invasive alien species (IAS). IAS are exotic species that pose a threat to native ecosystems, economies and/or human health. It is widely believed that IAS are the second most significant threat to biodiversity worldwide, following habitat destruction. In recognition of the threat posed by IAS the Convention on Biological Diversity puts forward the following strategy to all parties in Article 8h: “each contracting party shall as far as possible and as appropriate: prevent the introduction of, control, or eradicate those alien species which threaten ecosystems, habitats or species”. The National Assembly of Cambodia ratified the Convention on Biological Diversity in 1995. After reviewing the status of exotic species in the Tonle Sap from the literature, as well as the results from a survey based on questionnaires distributed among local communities, the main issues are discussed, possible strategies to combat the spread of alien species that are potentially invasive are examined, and recommendations are made to facilitate the implementation of a strategy towards reducing the impact of these species on the TSBR ecosystem.
