“…It is of biogeographic note that the Usumacinta River ichthyofauna includes 18 species with marine ancestry. This river system drains an eroded carbonate and limestone karst formation (Miller, 1966;Myers, 1966;West et al, 1969) and uplift of this formation potentially created an isolated high ionic habitat permitting marine fish to gradually shift to freshwater tolerance.…”

“…Despite recent gains toward understanding the biogeography of Central American freshwater fishes (Matamoros et al, 2012(Matamoros et al, , 2015, very little is known about the distribution and basic ecology of fishes in the small upland streams of the interior highlands (Miller, 1966, Lyons, 2005, Esselman et al, 2006. Livebearers (Poeciliidae) comprise a substantial portion of the Central American freshwater fish diversity, and are common in most aquatic habitats throughout the region (for example, Matamoros et al, 2009Matamoros et al, , 2012Matamoros et al, , 2015McMahan et al, 2013;Angulo et al, 2013).…”

Reproductive life history of Heterandria bimaculata (Heckel, 1848) (Poeciliinae: Poeciliidae) in the Honduran interior highlands: trait variation along an elevational gradient

This study examined reproductive traits and growth rates of Heterandria bimaculata (Poeciliidae) in Cusuco National Park (CNP), a cloud forest reserve in northern Honduras, Central America. In CNP, H. bimaculata occurs in the absence of other fish species and major invertebrate predators along an approximately 1000 m elevation gradient. This allowed for the examination of trait variation along the gradient without the confounding effects of interspecific interactions or habitat patchiness. Heterandria bimaculata exhibited traits characteristic of a low-predation environment: balanced sex ratio, slow growth, late maturity and large female size. Females produced more, smaller eggs from upstream to downstream, but overall reproductive allocation remained constant along the gradient. Maximum male length and annual growth rates increased from upstream to downstream, but female growth showed no trend. The patterns of growth and reproductive allocation tradeoff are consistent with predicted response to a longitudinally-increasing productivity gradient in which food resources become more abundant downstream. Macrobrachium and Bellastoma could have caused some predation, but were sparse and patchily distributed. Fish density remained fairly constant among elevations; if food resources were limiting in upstream habitats, per-capita resource availability would be lower and density-dependent competition would drive selection for larger but fewer, more competitive offspring. Future work should quantify longitudinal changes in productivity and conduct experiments to decouple the effects of stream order and fish density dependence.Este estudo analisou características reprodutivas e taxas de crescimento de Heterandria bimaculata (Poeciliidae) no Parque Nacional de Cusuco (CNP), uma reserva florestal nubosa no norte de Honduras, América Central. No CNP, H. bimaculata ocorre na ausência de outras espécies de peixes e grandes predadores invertebrados, ao longo de um gradiente de aproximadamente 1.000 m de altitude. Isto permitiu a análise de variação das características ao longo do gradiente sem a interferência dos efeitos de interações interespecíficas ou desconexão de hábitat. Heterandria bimaculata exibiu traços característicos de um ambiente de baixa predação: proporção sexual equilibrada, de crescimento lento, maturidade tardia e fêmeas de grande porte. As fêmeas produzem mais ovos menores de montante para jusante, mas a alocação reprodutiva global manteve-se constante ao longo do gradiente. O comprimento máximo dos machos e as taxas de crescimento anual aumentaram da montante para jusante, mas o crescimento as fêmeas não mostrou nenhuma tendência. Os padrões de crescimento e alteração de alocação reprodutiva são consistentes com a resposta prevista para um gradiente de produtividade que aumenta longitudinalmente, no qual os recursos alimentares se tornam mais abundantes a jusante. Macrobrachium e Bellastoma poderiam ter causado alguma predação, mas foram escassos e pouco distribuídos. A densidade de peixes manteve-se relativ...

“…However, the dispersion of freshwater fish and some other aquatics are strictly limited by hydrological barriers. Though many of them exhibit inter-watershed distribution caused by physiographic changes of land or occasional anastomosing of river systems during flood seasons throughout history (Loxterman and Keeley, 2012;Miller, 1966), they cannot naturally disperse across current hydrological barriers. Thus, it might be more appropriate to delineate distribution ranges of these taxa according to hydrological boundaries rather than predict them by using geographical variables in SDM.…”

Although China has established more than 600 wetland nature reserves, conservation gaps still exist for many species, especially for freshwater fishes. Underlying this problem is the fact that top-level planning is missing in the construction of nature reserves. To promote the development of nature reserves for fishes, this study took the middle and lower reaches of the Yangtze River basin (MLYRB) as an example to carry out top-level reserve network planning for fishes using approaches of systematic conservation planning. Typical fish species living in freshwater habitats were defined and considered in the planning. Based on sample data collected from large quantities of literatures, continuous distribution patterns of 142 fishes were obtained with species distribution modeling and subsequent processing, and the distributions of another eleven species were artificially designated. With the distribution pattern of species, Marxan was used to carry out conservation planning. To obtain ideal solutions with representativeness, persistence, and efficiency, parameters were set with careful consideration regarding existing wetland reserves, human disturbances, hydrological connectivity, and representation targets of species. Marxan produced the selection frequency of planning units (PUs) and a best solution. Selection frequency indicates the relative protection importance of a PU. The best solution is a representative of ideal fish reserve networks. Both of the PUs with high selection frequency and those in the best solution have low proportions included in existing wetland nature reserves, suggesting that there are significant conservation gaps for fish species in MLYRB. The best solution could serve as a reference for establishing a fish reserve network in the MLYRB. There is great flexibility for replacing selected PUs in the solution, and such flexibility facilitates the implementation of the solution in reality in case of unexpected obstacles. Further, we suggested adopting a freshwater management framework in the implementation of such solution.middle and lower Yangtze River basin, fish conservation, systematic conservation planning, reserve network, Marxan Citation:Huang, X., Li, F., and Chen, J.
