Elevational Gradients Do Not Affect Thermal Tolerance at Local Scale in Populations of Livebearing Fishes of the Genus Limia (Cyprinodontiformes: Poeciliinae)
46 NOVITATES CARIBAEA 18: 46–62, 2021 ELEVATIONAL GRADIENTS DO NOT AFFECT THERMAL TOLERANCE AT LOCAL SCALE IN POPULATIONS OF LIVEBEARING FISHES OF THE GENUS LIMIA (CYPRINODONTIFORMES: POECILIINAE) Gradientes de elevación no afectan la tolerancia térmica a escala local en poblaciones de peces vivíparos del género Limia (Cyprinodontiformes: Poeciliinae) Rodet Rodriguez-Silva1a* and Ingo Schlupp1b 1Department of Biology, University of Oklahoma, 730 Van Vleet Oval, Norman, OK 73019; 1a orcid.org/0000– 0002–7463–8272; 1b orcid.org/0000–0002–2460–5667, [email protected]. *Corresponding author: rodet.rodriguez. [email protected]. ABSTRACT One of the main assumptions of Janzen’s mountain passes hypothesis is that due the low overlap in temperature regimes between low and high elevations in the tropics, organisms living in high-altitude evolve narrow tolerance for colder temperatures while low-altitude species develop narrow tolerance for warmer temperatures. Some studies have questioned the generality of the assumptions and predictions of this hypothesis suggesting that other factors different to temperature gradients between low and high elevations may explain altitudinal distribution of species in the tropics. In this study we test some predictions of the Janzen’s hypothesis at local scales through the analysis of the individual thermal niche breadth in populations of livebearing fishes of the genus Limia and its relationship with their altitudinal distribution in some islands of the Greater Antilles. We assessed variation in tolerance to extreme temperatures (measured as critical thermal minimum (CTmin) and maximum (CTmax) and compared thermal breadth for populations of eight species of Limia occurring in three Caribbean islands and that occupy different altitudinal distribution. -

The Evolution of the Placenta Drives a Shift in Sexual Selection in Livebearing Fish
LETTER doi:10.1038/nature13451 The evolution of the placenta drives a shift in sexual selection in livebearing fish B. J. A. Pollux1,2, R. W. Meredith1,3, M. S. Springer1, T. Garland1 & D. N. Reznick1 The evolution of the placenta from a non-placental ancestor causes a species produce large, ‘costly’ (that is, fully provisioned) eggs5,6, gaining shift of maternal investment from pre- to post-fertilization, creating most reproductive benefits by carefully selecting suitable mates based a venue for parent–offspring conflicts during pregnancy1–4. Theory on phenotype or behaviour2. These females, however, run the risk of mat- predicts that the rise of these conflicts should drive a shift from a ing with genetically inferior (for example, closely related or dishonestly reliance on pre-copulatory female mate choice to polyandry in conjunc- signalling) males, because genetically incompatible males are generally tion with post-zygotic mechanisms of sexual selection2. This hypoth- not discernable at the phenotypic level10. Placental females may reduce esis has not yet been empirically tested. Here we apply comparative these risks by producing tiny, inexpensive eggs and creating large mixed- methods to test a key prediction of this hypothesis, which is that the paternity litters by mating with multiple males. They may then rely on evolution of placentation is associated with reduced pre-copulatory the expression of the paternal genomes to induce differential patterns of female mate choice. We exploit a unique quality of the livebearing fish post-zygotic maternal investment among the embryos and, in extreme family Poeciliidae: placentas have repeatedly evolved or been lost, cases, divert resources from genetically defective (incompatible) to viable creating diversity among closely related lineages in the presence or embryos1–4,6,11. -

A REVISION of the GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT in Addition to Gambusia
Reprinted from PUBLICATIONS OF THE GULF COAST RESEARCH LABORATORY MUSEUM 2:47-77, June 18, 1971 A REVISION OF THE GAMBUSIA NICARAGUENSIS SPECIES GROUP (PISCES:POECILIIDAE) by William L. Fink ABSTRACT In addition to Gambusia nicaraguensis, the species group includes G. wrayi, G. mela pleura and G. his paniolae sp. nov. G. gracilior is a junior synonym of G. wrayi and G. dominicensis is found to be a member of another species group. A key and zoogeographical notes are provided for the group. Rivas (1963) published on subgenera and species groups in the genus Gambusia. He used only gonopodial characters in defining his groups, and I believe that his system is both natural and practical. Subsequent investigation has shown a need to review his findings and to make adjust- ments in the system. I have found that G. dominicensis is a member of another species group and that the species referred to as dominicensis by Rivas (1963) is actually undescribed. Otherwise, I accept his G. nicara- guensis species group and feel that its revision will help clarify other prob- lems within the genus. METHODS.—Methods are those of Fink (1971).

Esta surge en el marco del 6to aniversario de la fundación del Parque Zoológico Nacional de Cuba cuando a pesar de no haberse terminado su construcción ya se contaba con gran experiencia en la atención a los animales exóticos en cautiverio, de forma interdisciplinaria en las ramas de Biología, Veterinaria, y Nutrición, por sólo citar algunas. Todo este conocimiento alcanzado hasta el momento era imprescindible comenzarlo a divulgar, por lo cual se inicia la edición de la revista impresa; muy simple y modesta al inicio pero con los deseos y la perspectiva de ampliar su formato y llegar a otros niveles de consumo como se planteó en la Carta Editorial del primer número.

Acknowledgements………………………………………………………..………. 14 Literature Cited……………….………………………………………….……….. 14 2 Introduction A major goal of the Water Development Board's mission are its research, monitoring, and assessment programs designed to minimize the effects of water development projects on the affected native aquatic fauna and to maintain the quality and availability of instream habitats for the use of dependent aquatic resources. The instream flows necessary for the successful survival, growth and reproduction of affected aquatic life are a major concern. Unfortunately, instream flow data with respect to the ecological requirements of Texas riverine fishes are largely unknown. While some information can be found in the published literature, a substantial but unknown quantity of information is also present in various agencies and research museums around the state. In order to minimize the disruptions to the native fauna, quantitative and qualitative information concerning life histories, survival, -
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.

Wong Abstract Two North American species of mosquitofish, the Western (Gambusia affinis Baird and Girard, 1853) and Eastern mosquitofish (G. holbrooki Girard, 1859), rank amongst the most invasive freshwater fishes worldwide. While the existing literature suggests that G. affinis was introduced to mainland China, empirical evidence supporting this assumption was limited, and the possibility remained that both species were introduced during campaigns attempting to reduce vectors of malaria and dengue fever. We used combined molecular information (based on phylogenetic analyses of sequence variation of the mitochondrial cytochrome b gene) and morphometric data (dorsal and anal fin ray counts) to confirm the presence -
