“…Behavioral variation within species sets a challenge for conservation, and suggests that using watersheds as units of management will favor the effective migration of fish in all their life stages and connectivity within populations to reduce the risk of local extinctions (McDowall, 1992(McDowall, , 1999(McDowall, , 2008. This is important for A. monticola, because genetic, molecular, and morphometric analyses demonstrated that this species represents more than 1 taxon (Díaz-Murillo et al, 2017;Durand et al, 2012;McMahan, Davis et al, 2013) and for S. multipunctatum, whose ecological and biological knowledge is limited and whose taxonomy is currently under debate (Chabarria & Pezold, 2013).…”

In the Acahuapa River watershed, the distribution, abundance, and length structure of A. monticola and S. multipunctatum were assessed in its tributary rivers and main channel for 1 year. Fishes were captured using electrofishing devices and nets. Environmental variables, habitat traits, and land use around the sampling points were taken into consideration. A total of 222 A. monticola and 183 S. multipunctatum were recorded during the sampled year. Their distribution was restricted to 8 of the 17 sampling points. Both species co-occurred at 7 of 8 sites, all at elevations between 19 and 325 m asl. Both species were more abundant in lower parts of the watershed and in the tributary rivers than in the main channel. Water temperature, dissolved oxygen, river width and depth, current speed, substrata dominated by rocks and logs, and surroundings of forest and small-scale agriculture favor the presence of these fishes. The smaller individuals of A. monticola occurred at lower elevations of the watershed but fish length differences were not present at the main channel or at the tributaries. For S. multipunctatum, the larger fish were captured also at low elevations and at the main channel of the Acahuapa River watershed. ResumenLos peces diádromos cambian de hábitat durante su ciclo de vida ocupando ambientes diferentes. En la cuenca del río Acahuapa, la distribución, abundancia y estructura de tallas de A. monticola y S. multipunctatum fueron evaluadas en sus ríos tributarios y en el canal principal durante 1 año. Los peces fueron capturados utilizando dispositivos de electropesca y trasmallos. Las variables ambientales, características del hábitat y el uso de suelo en los puntos de muestreo fueron cuantificados. Un total de 222 ejemplares de A. monticola y 183 de S. multipunctatum fueron registrados durante el año de muestreo. Su distribución estuvo restringida a 8 de los 17 sitios de muestreo coincidiendo en 7 de ellos, en alturas entre 19 y 325 m snm. Ambas especies fueron más abundantes en las partes bajas de la cuenca y en los ríos tributarios. La temperatura del agua, oxígeno disuelto, ancho y profundidad del río, velocidad de la corriente y sustrato dominado por rocas, troncos y rodeado por bosque o agricultura a pequeña escala favorecen la presencia de estos peces. Los peces de menor tamaño de A. monticola se encontraron en la parte baja de la cuenca sin importar si este es un río tributario o el canal principal. Peces de S. multipunctatum de mayor tamaño se capturaron S. González-Murcia, F.S. Álvarez / Revista Mexicana de Biodiversidad 89 (2018): 854 -864 855 https://doi.

“…Compared to stenohaline or euryhaline fishes, diadromous fishes can exhibit interesting patterns of evolutionary history and population structure given their occupancy of both freshwater and marine systems as integral parts of their life histories. These structured biogeographic patterns have been observed in several diadromous taxa in Middle America, including sleepers (family Eleotridae, Guimarães‐Costa et al ., 2017 and Galván‐Quesada et al ., 2016) and mullets (family Mugilidae, Díaz‐Murillo et al ., 2017 and McMahan et al ., 2013). Intraspecific divergence was recovered across all of these taxa, with different lineages present in Atlantic and Pacific‐slope rivers, as well as multiple lineages within each slope.…”

Diadromous fishes can exhibit interesting evolutionary and population‐level patterns given their use of freshwater and marine environments as part of their life histories. The River goby genus Awaous are prominent members of riverine ichthyofaunas and occur throughout Atlantic and Pacific slopes of the Americas from the southern United States to Ecuador and Brazil. Here we study the widespread and polymorphic Awaous banana complex to assess phylogeographic patterns and test previous hypotheses that all populations of this species in the Americas belong to the same species. Analysis of sequence data based on the mitochondrial cytochrome oxidase I gene shows multiple clades within the Atlantic and Pacific basins, which correspond to previously described species. Additionally, haplotype analysis demonstrates unique and unconnected networks between these species. Within these clades we document biogeographic patterns that are congruent with results of other co‐occurring diadromous species, as well as a novel biogeographic pattern for the region. Our results support the recognition of distinct species of Awaous in the Atlantic (A. banana and A. tajasica) and Pacific (A. transandeanus) basins. These results are concordant with previously established morphological characters permitting the separation of these species.

In this study, we describe a new species of Pseudoparacreptotrema (Allocreadiidae) from the mugilid Dajaus monticola collected in western Puerto Rico, where no allocreadiid has previously been reported, bringing the number of species in this genus to seven (five in D. monticola, two in Profundulus spp.). The new parasite species is distinguished from congeners by its overall size, oral-to-ventral sucker size ratio, pharynx size, cirrus sac, and oral lobe morphology, and by 0.64%–3.45% divergence in a 1019-bp alignment of 28S. We build on prior suggestions that the current concept of P. agonostomi likely includes multiple species and provide the first mitochondrial data (whole mitochondrial genome) as well as the complete nuclear rDNA array from Pseudoparacreptotrema to facilitate future phylogenetic work. Within the Allocreadiidae, phylogenetic analysis of mitochondrial genomes and 28S provides conflicting topologies for the placement of Pseudoparacreptotrema and Allocreadium. The 28S phylogeny of six species of Pseudoparacreptotrema resembles that of four lineages of D. monticola in that in both host and parasite, Pacific coastal lineages branch earliest, and a Caribbean lineage is more recently evolved.
