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. -

BASOLO Nebraska Behavioral Biobgy Group, University of Nebraska, Lincoln, Nebraska 68510, USA; E-mail: [email protected] Abstract.—Robust phylogenetic information can be instrumental to the study of the evolution of female mating preferences and preferred male traits. In this paper, the evolution of a preexisting female bias favoring a sword in male swordtail fish and the evolution of the sword, a complex character, are used to demonstrate how the evolution of mating preferences and preferred traits can be examined in a phylogenetic context. Phylogenetic information suggests that a preference for a sword arose prior to the evolution of the sword in the genus Xiphophorus and that the sword was adaptive at its origin. A phylogenetic approach to the study of female preferences and male traits can also be informative when used in conjunction with mate choice theory in making predictions about evolutionary changes in an initial bias, both prior to the appearance of the male trait it favors and subsequent to the appearance of the trait. -

The Endangered White Sands Pupfish (Cyprinodon Tularosa)
The Endangered White Sands pupfish (Cyprinodon tularosa) genome reveals low diversity and heterogenous patterns of differentiation Andrew Black1, Janna Willoughby2, Anna Br¨uniche-Olsen3, Brian Pierce4, and Andrew DeWoody1 1Purdue University 2Auburn University 3University of Copenhagen 4Texas A and M University College Station November 24, 2020 Abstract The White Sands pupfish (Cyprinodon tularosa), endemic to New Mexico in Southwestern North America, is of conservation concern due in part to invasive species, chemical pollution, and groundwater withdrawal. Herein, we developed a high quality draft reference genome and use it to provide biological insights into the evolution and conservation of C. tularosa. Specifically, we localized microsatellite markers previously used to demarcate Evolutionary Significant Units, evaluated the possibility of introgression into the C. tularosa genome, and compared genomic diversity among related species. The de novo assembly of PacBio Sequel II error-corrected reads resulted in a 1.08Gb draft genome with a contig N50 of 1.4Mb and 25,260 annotated protein coding genes, including 95% of the expected Actinopterigii conserved orthologs. Many of the previously described C. tularosa microsatellite markers fell within or near genes and exhibited a pattern of increased heterozygosity near genic areas compared to those in intergenic regions. Genetic distances between C. tularosa and the widespread invasive species C. variegatus, which diverged ~1.6-4.7 MYA, were 0.027 (nuclear) and 0.022 (mitochondrial). Nuclear alignments revealed putative tracts of introgression that merit further investigation. Genome-wide heterozygosity was markedly lower in C. tularosa compared to estimates from related species, likely because of smaller long-term effective population sizes constrained by their isolated and limited habitat. -
Genetic Linkage and Color Polymorphism in the Southern Platyfish (Xiphophorus Maculatus): a Model System for Studies of Color Pattern Evolution
ZEBRAFISH Volume 3, Number 1, 2006 © Mary Ann Liebert, Inc. Genetic Linkage and Color Polymorphism in the Southern Platyfish (Xiphophorus maculatus): A Model System for Studies of Color Pattern Evolution ALEXANDRA L. BASOLO ABSTRACT Color pattern polymorphisms are widespread in animals, and are found within populations, among populations, and among species. The southern platyfish, Xiphophorus maculatus, represents one of the most extreme examples of color pattern polymorphism. Extensive research with this model system for melanoma formation has resulted in an understanding of the underlying genetic basis of over 40 sex-linked and autosomal color patterns, includ- ing alleles that code for melanin, pterin, and carotenoid coloration. Research has also found that genes that affect sex determination, timing of sexual maturation, and coloration are genetically linked on the sex chromosomes. In many animals, color patterns often show strong sexual dimorphism, with conspicuous coloration limited to males. Although some of the color pattern alleles are sex-limited in platyfish, many are expressed by both sexes. Despite the abundance of work on this model system, little is known about the evolutionary processes responsible for this diversity of color pattern alleles. This review discusses what is known about platyfish coloration, and the roles that genetic linkage and variation in environmental conditions within and among populations might play in the evolution and maintenance of the extreme color pattern polymorphism exhibited by this platyfish.

STATUS OF INTRODUCED FISHES IN CERTAIN SPRING SYSTEMS IN SOUTHERN NEVADA Walter R. Courtenay, Jr.," and James E. Deacon^ .Abstract.— We record eight species of exotic fishes as established, reproducing populations in certain springs in Clark, Lincoln, and Nye counties. Nevada. These include an unidentified species of Hi/postomus, Cyprinus carpio, Poecilia mexicana. Poecilia reticulata, a Xiphophorus hybrid, and Cichlasoma nigrofasciatiim. Tilapia mariae, estab- lished in a spring near the Overton Arm of Lake Mead, and Tilapia zilli, established in a golf course pond in Pah- rump Valley, are recorded for the first time from Nevada waters. Though populations of transplanted Gambusia af- finis persist, other populations of Poecilia latipinna are apparently no longer extant. Cichlasoma severum, Notemigomis crysoleucas, Poecilia latipinna, and Carassius auratus were apparently eradicated from Rogers Spring in 1963.

ZooKeys 874: 31–45. https://doi.org/10.3897/zookeys.874.35618 Abstract Species checklists and dichotomous keys are valuable tools that provide many services for ecological stud- ies and management through tracking native and non-native species through time. We developed nine drainage basin checklists and dichotomous keys for 196 inland fishes of Texas, consisting of 171 native fishes and 25 non-native fishes. Our checklists were updated from previous checklists and revised using reports of new established native and non-native fishes in Texas, reports of new fish occurrences among drainages, and changes in species taxonomic nomenclature. We provided the first dichotomous keys for major drainage basins in Texas. Among the 171 native inland fishes, 6 species are considered extinct or extirpated, 13 species are listed as threatened or endangered by U.S. Fish and Wildlife Service, and 59 spe- cies are listed as Species of Greatest Conservation Need (SGCN) by the state of Texas.
