Email: [email protected] Abstract: This checklist aims to list all the reported cyprinodontid fishes (superfamily Cyprinodontoidea/pupfishes) of the world. It lists 141 species in 8 genera and 4 families. The most diverse family is Cyprinodontidae (54 species, 38%), followed by Orestiidae (45 species, 32%), Aphaniidae (39 species, 28%), and Cubanichthyidae (3 species, 2%). Among 141 listed species, 73 (51.8%) species are Not Evaluated (NE), 15 (10.6%) Least Concern (LC), 9 (6.4%) Vulnerable (VU), 3 (2.1%) Data Deficient (DD), 11 (7.8%) Critically Endangered (CR), 4 (2.8%) Near Threatened (NT), 18 (12.8%) Endangered (EN), 3 (2.1%) Extinct in the Wild (EW) and 5 (3.5%) Extinct of the Red List of IUCN. They inhabit in the fresh, brackish and marine waters of the United States, Middle America, the West Indies, parts of northern South America, North Africa, the Mediterranean Anatolian region, coastal areas of the Persian Gulf and Makran Sea (Oman Sea), the northern Arabian Sea east to Gujarat in India, and some endorheic basins of Iran, Pakistan and the Arabian Peninsula.

  • Novel Trophic Niches Drive Variable Progress Towards Ecological Speciation Within an Adaptive Radiation of Pupfishes
    Molecular Ecology (2014) 23, 1846–1862 doi: 10.1111/mec.12658 Novel trophic niches drive variable progress towards ecological speciation within an adaptive radiation of pupfishes CHRISTOPHER H. MARTIN*† and LAURA C. FEINSTEIN†‡ *Department of Environmental Science, Policy, and Management, University of California, Berkeley, CA 94720, USA, †Department of Evolution & Ecology, University of California, Davis, CA 94616, USA, ‡California Council on Science and Technology, 1130 K Street, Sacramento, CA 95814, USA Abstract Adaptive radiation is recognized by a rapid burst of phenotypic, ecological and species diversification. However, it is unknown whether different species within an adaptive radiation evolve reproductive isolation at different rates. We compared patterns of genetic differentiation between nascent species within an adaptive radiation of Cyprin- odon pupfishes using genotyping by sequencing. Similar to classic adaptive radiations, this clade exhibits rapid morphological diversification rates and two species are novel trophic specialists, a scale-eater and hard-shelled prey specialist (durophage), yet the radiation is <10 000 years old. Both specialists and an abundant generalist species all coexist in the benthic zone of lakes on San Salvador Island, Bahamas. Based on 13 912 single-nucleotide polymorphisms (SNPs), we found consistent differences in genetic differentiation between each specialist species and the generalist across seven lakes. The scale-eater showed the greatest genetic differentiation and clustered by species across lakes, whereas durophage populations often clustered with sympatric generalist populations, consistent with parallel speciation across lakes. However, we found strong evidence of admixture between durophage populations in different lakes, sup- porting a single origin of this species and genome-wide introgression with sympatric generalist populations.

  • Introductions of Threatened and Endangered Fishes (Full Statement)
    AFS Policy Statement #19: Introductions of Threatened and Endangered Fishes (Full Statement) ABSTRACT Introductions of threatened and endangered fishes are often an integral feature in their recovery programs. More than 80% of threatened and endangered fishes have recovery plans that call for introductions to establish a new population or an educational exhibit, supplement an existing population, or begin artificial propagation. Despite a large number of recent and proposed introductions, no systematic procedural policies have been developed to conduct these recovery efforts. Some introductions have been inadequately planned or poorly implemented. As a result, introductions of some rare fishes have been successful, whereas recovery for others has progressed slowly. In at least one instance, the introduced fish eliminated a population of another rare native organism. We present guidelines for introductions of endangered and threatened fishes that are intended to apply when an introduction is proposed to supplement an existing population or establish a new population. However, portions of the guidelines may be helpful in other Situations, such as establishing a hatchery stock. The guidelines are divided into three components: (1) selecting the introduction site, (2) conducting the introduction, and (3) post-introduction monitoring, reporting, and analysis. Implementation should increase success of efforts to recover rare fishes. "On 3 August 1968, we collected 30 or 40 individuals from among the inundated prickly pear and mesquite near the flooded spring, which by that time was covered with about 7 m of clear water." Peden (1973) The above quote described the collection of Amistad gambusia, Gambusia amistadensis, as its habitat was being flooded. Fortunately, most translocations of endangered fishes do not occur under such a feverish pace as did this collection of Amistad gambusia.

  • The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish

  • Building Trophic Specializations That Result in Substantial Niche
    Journal of Anatomy J. Anat. (2017) doi: 10.1111/joa.12742 Building trophic specializations that result in substantial niche partitioning within a young adaptive radiation Luz Patricia Hernandez,1 Dominique Adriaens,2 Christopher H. Martin,3 Peter C. Wainwright,4 Bert Masschaele5 and Manuel Dierick5 1Department of Biological Sciences, The George Washington University, Washington, DC, USA 2Evolutionary Morphology of Vertebrates, Ghent University, Ghent, Belgium 3Department of Biology, University of North Carolina, Chapel Hill, Chapel Hill, NC, USA 4Department of Evolution & Ecology, University of California, Davis, Davis, CA, USA 5Department of Subatomic and Radiation Physics, Ghent University, Ghent, Belgium Abstract Dietary partitioning often accompanies the increased morphological diversity seen during adaptive radiations within aquatic systems. While such niche partitioning would be expected in older radiations, it is unclear how significant morphological divergence occurs within a shorter time period. Here we show how differential growth in key elements of the feeding mechanism can bring about pronounced functional differences among closely related species. An incredibly young adaptive radiation of three Cyprinodon species residing within hypersaline lakes in San Salvador Island, Bahamas, has recently been described. Characterized by distinct head shapes, gut content analyses revealed three discrete feeding modes in these species: basal detritivory as well as derived durophagy and lepidophagy (scale-feeding). We dissected, cleared and stained, and micro-CT scanned species to assess functionally relevant differences in craniofacial musculoskeletal elements. The widespread feeding mode previously described for cyprinodontiforms, in which the force of the bite may be secondary to the requisite dexterity needed to pick at food items, is modified within both the scale specialist and the durophagous species.

De éstas, 81% son endémicas de la provincia biogeográfica chilena y 40% se encuentran clasificadas en peligro de extinción. Los grupos más representados corresponden a los órdenes Siluriformes (11 especies), Osmeriformes (9 especies) y Atheriniformes (7 especies). También están representados en Chile los ciclóstomos Petromyzontiformes (2 especies), y los teleósteos Characiformes (4 especies), Cyprinodontiformes (6 especies), Perciformes (4 especies) y Mugilifromes (1). Latitudinalmente, la mayor riqueza de especies ocurre en la zona centro-sur de la provincia Chilena, en tanto que los extremos norte y sur son de baja riqueza específica. Dado su origen, porcentaje de endemismo y retención de caracteres primitivos, este conjunto ictiofaunístico es de alto valor biogeográfico y de conservación.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • Cyprinodon Nevadensis Mionectes Ash Meadows Amargosa Pupfish
    Ash Meadows Amargosa pupfsh Cyprinodon nevadensis mionectes WAP 2012 species due to impacts from introduced detrimental aquatc species, habitat degradaton, and federal endangered status. Agency Status NV Natural Heritage G2T2S2 USFWS LE BLM-NV Sensitve State Prot Threatened Fish NAC 503.065.3 CCVI Presumed Stable TREND: Trend is stable to increasing with contnued on-going restoraton actvites. DISTRIBUTION: Springs and associated springbrooks, outlow stream systems and terminal marshes within Ash Meadows Natonal Wildlife Refuge, Nye Co., NV. GENERAL HABITAT AND LIFE HISTORY: This species is isolated to warm springs and outlows in Ash Meadows NWR including Point of Rocks, Crystal Springs, and the Carson Slough drainage. Pupfshes feed generally on substrate; feeding territories are ofen defended by pupfshes. Diet consists of mainly algae and detritus however, aquatc insects, crustaceans, snails and eggs are also consumed. Spawning actvity is typically from February to September and in some cases year round. Males defend territories vigorously during breeding season (Soltz and Naiman 1978). In warm springs, fsh may reach sexual maturity in 4-6 weeks. Reproducton variable: in springs, pupfsh breed throughout the year, may have 8-10 generatons/year; in streams, breeds in spring and summer, 2-3 generatons/year (Moyle 1976). In springs, males establish territories over sites suitable for ovipositon. Short generaton tme allows small populatons to be viable. Young adults typically comprise most of the biomass of a populaton. Compared to other C. nevadensis subspecies, this pupfsh has a short deep body and long head with typically low fn ray and scale counts (Soltz and Naiman 1978). CONSERVATION CHALLENGES: Being previously threatened by agricultural use of the area (loss and degradaton of habitat resultng from water diversion and pumping) and by impending residental development, the TNC purchased property, which later became the Ash Meadows NWR.
