    State of research of the Osteichthyes fish related to coral reefs in the Honduran Caribbean with catalogued records Estado del conocimiento de los peces osteíctios asociados a los arrecifes de coral en el Caribe de Honduras, con registros catalogados Anarda Isabel Salgado Ordoñez1, Julio Enrique Mérida Colindres1* & Gustavo Adolfo Cruz1 ABSTRACT Research on Honduran coral reef fish has been isolated and scattered. A list of fish species related to coral reefs was consolidated to establish a compiled database with updated taxonomy. The study was conducted between October 2017 and December 2018. Using primary and secondary sources, all potential species in the Western Atlantic were considered, and their actual presence was confirmed using catalogued records published in peer-reviewed journals that included Honduras. In addition, the specimens kept in the Museum of Natural History of Universidad Nacional Autónoma de Honduras were added. Once the list was consolidated, the taxonomic status of each species was updated based on recent literature. A total of 159 species and 76 genera were registered in 32 families. The family with the most species was Labrisomidae with 27 species (17%). Five families had more than five 5 genera registered, while four 4 were represented by more than 16 species, which is equivalent to 42% genera and 51% species. Gobiidae was represented by 10 genera (13%) and 21 species (13%), of which two 2 were endemic: Tigrigobius rubrigenis and Elacatinus lobeli. In turn, Grammatidae was represented by one endemic species Lipogramma idabeli (1.8%). The species Diodon holocanthus and Sphoeroides testudineus represent the first catalogued records for Honduras.

  • Alikes Among Tropical Reef Fishes
    Who Resembles Whom? Mimetic and Coincidental Look- Alikes among Tropical Reef Fishes D. Ross Robertson* Smithsonian Tropical Research Institute, Balboa, Republic of Panama´ Abstract Studies of mimicry among tropical reef-fishes usually give little or no consideration to alternative explanations for behavioral associations between unrelated, look-alike species that benefit the supposed mimic. I propose and assess such an alternative explanation. With mimicry the mimic resembles its model, evolved to do so in response to selection by the mimicry target, and gains evolved benefits from that resemblance. In the alternative, the social-trap hypothesis, a coincidental resemblance of the model to the ‘‘mimic’’ inadvertently attracts the latter to it, and reinforcement of this social trapping by learned benefits leads to the ‘‘mimic’’ regularly associating with the model. I examine three well known cases of supposed aggressive mimicry among reef-fishes in relation to nine predictions from these hypotheses, and assess which hypothesis offers a better explanation for each. One case, involving precise and complex morphological and behavioral resemblance, is strongly consistent with mimicry, one is inconclusive, and one is more consistent with a social- trap based on coincidental, imprecise resemblance. Few cases of supposed interspecific mimicry among tropical reef fishes have been examined in depth, and many such associations may involve social traps arising from generalized, coincidental resemblance. Mimicry may be much less common among these fishes than is generally thought. Citation: Robertson DR (2013) Who Resembles Whom? Mimetic and Coincidental Look-Alikes among Tropical Reef Fishes.

Its mission is to identify, designate, protect and manage the ecological, recreational, research, educational, historical, and aesthetic resources and qualities of nationally significant coastal and marine areas. The existing marine sanctuaries differ widely in their natural and historical resources and include nearshore and open ocean areas ranging in size from less than one to over 5,000 square miles. Protected habitats include rocky coasts, kelp forests, coral reefs, sea grass beds, estuarine habitats, hard and soft bottom habitats, segments of whale migration routes, and shipwrecks. Because of considerable differences in settings, resources, and threats, each marine sanctuary has a tailored management plan. Conservation, education, research, monitoring and enforcement programs vary accordingly. The integration of these programs is fundamental to marine protected area management. The Marine Sanctuaries Conservation Series reflects and supports this integration by providing a forum for publication and discussion of the complex issues currently facing the National Marine Sanctuary Program.

  • Inter-Chromosomal Coupling Between Vision and Pigmentation Genes During Genomic Divergence
    ARTICLES https://doi.org/10.1038/s41559-019-0814-5 Inter-chromosomal coupling between vision and pigmentation genes during genomic divergence Kosmas Hench 1*, Marta Vargas2, Marc P. Höppner3, W. Owen McMillan2 and Oscar Puebla 1,2,4* Recombination between loci underlying mate choice and ecological traits is a major evolutionary force acting against speciation with gene flow. The evolution of linkage disequilibrium between such loci is therefore a fundamental step in the origin of spe- cies. Here, we show that this process can take place in the absence of physical linkage in hamlets—a group of closely related reef fishes from the wider Caribbean that differ essentially in colour pattern and are reproductively isolated through strong visually-based assortative mating. Using full-genome analysis, we identify four narrow genomic intervals that are consistently differentiated among sympatric species in a backdrop of extremely low genomic divergence. These four intervals include genes involved in pigmentation (sox10), axial patterning (hoxc13a), photoreceptor development (casz1) and visual sensitivity (SWS and LWS opsins) that develop islands of long-distance and inter-chromosomal linkage disequilibrium as species diverge. The relatively simple genomic architecture of species differences facilitates the evolution of linkage disequilibrium in the presence of gene flow. ow new species may arise and persist in the presence of gene Here, we focus on the lower end of the speciation continuum flow is a fundamental and unresolved question in our under- and examine patterns of genomic divergence among the three Hstanding of the origins of biological diversity.

    3.0 Description, Distribution and Use of Essential Fish Habitat 3.0 DESCRIPTION, DISTRIBUTION, AND USE OF ESSENTIAL FISH HABITAT 3.1 Estuarine and Inshore Habitats 3.1.1 Estuarine 3.1.1.1 Estuarine Emergent (Saltmarsh and Brackish Marsh) 3.1.1.1.1 Description and Ecological Role and Function The saltmarsh is a type of wetland. Wetlands are classified on the basis of their hydrology, vegetation and substrate. One classification system proposed by Cowardin et al., (1979) and used by the USFWS classifies wetlands into five ecological systems. Estuarine emergents fall into two of these systems, the Estuarine and Marine. The Estuarine wetland is described as tidal wetlands in low-wave-energy environments, where the salinity is greater than 0.5 parts per thousand (ppt) and is variable owing to evaporation and the mixing of seawater and freshwater. Marine wetlands are described as tidal wetlands that are exposed to waves and currents of the open ocean and have a salinity of greater than 30 ppt. A saltmarsh, as defined by Beeflink (1977), is a “natural or semi-natural salt tolerant grassland and dwarf brushwood on the alluvial sediments bordering saline water bodies whose water level fluctuates either tidal or nontidally”. The flora comprise of erect, rooted, herbaceous hydrophytes dominated by salt- tolerant perennial plants (Cowardin et al. 1979). Structure and function of a saltmarsh are influenced by tide, salinity, nutrients and temperature. The saltmarsh can be a stressful environment to plants and animals, with rapid changes occurring in these abiotic variables (Gosselink 1980; Gosselink et al. 1974). Although species diversity may be lower than in other systems, the saltmarsh is one of the most biologically productive ecosystems in the world (Teal 1962; Teal and Teal, 1969).
