The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described.

ABSTRACT Estuaries and coastal lagoons in tropical latitudes are highly productive sustaining a rich fauna and a high fish biomass. The aim of the present work was to analyze the food partitioning and the pattern of length weight relationship of three fish species of the Gerreidae family (Diapterus auratus, Diapterus rhombeus and Eucinostomus melanopterus) by sampling the Alvarado lagoon system in Mexico from July 2008 to May 2010. Salinity and dissolved oxygen were higher in the dry season, when low volumes of fresh water drained into the lagoons. D. rhombeus was the most abundant species It showed isometric growth in the windy season, but growth was negatively allometric in the wet and dry seasons. D. auratus was second in abundance, with isometric growth in the rainy season and a negatively allometric growth in the dry and windy seasons.

Crustaceans used were the hololimnetic FW Aegla schmitti, and Macrobrachium potiuna, the diadromous FW Macrobrachium acanthurus, the estuarine Palaemon pandaliformis and the marine Hepatus pudibundus; fishes used were the FW Corydoras ehrhardti, Mimagoniates microlepis, and Geophagus brasiliensis, and the marine-estuarine Diapterus auratus. The capacity for IIR was assessed in vitro following wet weight changes of isolated muscle slices incubated in anisosmotic saline (~50% change). M. potiuna was the crustacean with the highest capacity for IIR; the euryhaline perciforms G.

Zoosystema 39 (4): 501-598. https://doi.org/10.5252/z2017n4a5 ABSTRACT 313 nominal species of monogenean parasites of aquatic vertebrates occurring in Mexico are included in this checklist; in addition, records of 54 undetermined taxa are also listed. All the monogeneans registered are associated with 363 vertebrate host taxa, and distributed in 498 localities pertaining to 29 of the 32 states of the Mexican Republic. Th e checklist contains updated information on their hosts, habitat, and distributional records. We revise the species list according to current schemes of KEY WORDS classifi cation for the group. Th e checklist also included the published records in the last 11 years, Platyhelminthes, Mexico, since the latest list was made in 2006. We also included taxon mentioned in thesis and informal distribution, literature. As a result of our review, numerous records presented in the list published in 2006 were Actinopterygii, modifi ed since inaccuracies and incomplete data were identifi ed. Even though the inventory of the Elasmobranchii, Anura, monogenean fauna occurring in Mexican vertebrates is far from complete, the data contained in our Testudines.

    Zoologica Scripta Molecular and morphometric systematics of Diapterus (Perciformes, Gerreidae) FRANCISCO JAVIER VERGARA-SOLANA,FRANCISCO JAVIER GARCIA-RODRIGUEZ,JOSE JULIAN TAVERA, € EFRAIN DE LUNA &JOSE DE LA CRUZ-AGUERO Submitted: 30 December 2013 Vergara-Solana, F.J., Garcıa-Rodriguez, F.J., Tavera, J.J., De Luna, E. & De La Accepted: 7 March 2014 Cruz-Aguero,€ J. (2014). Molecular and morphometric systematics of Diapterus (Perciformes, doi:10.1111/zsc.12054 Gerreidae). — Zoologica Scripta, 00, 000–000. The fish belonging to Gerreidae are common representatives of the coastal ichthyofauna of the tropics and subtropics of the world. The genus Diapterus has a neotropical distri- bution and currently includes four species: two in the Atlantic Ocean [Irish mojarra D. auratus Ranzani 1842 and rhombic mojarra D. rhombeus (Cuvier 1829)] and two in the Pacific Ocean [short-beaked mojarra D. brevirostris (Sauvage 1879) and golden mojarra D. aureolus (Jordan & Gilbert 1882)]. This genus has uncertain taxonomy based on the remarkable and dissimilar morphology of D. aureolus. We evaluated the taxonomy and phylogeny of Diapterus with statistical (canonical discriminant analysis) and phyloge- netic analyses (maximum parsimony, maximum likelihood and Bayesian inference) of geo- metric morphometric data (relative warps) and molecular data (12Sr RNA, 16Sr RNA, COI and RAG1 sequences). Our results indicate that the genus Diapterus as we currently conceive it is a polyphyletic group: [(Gerres cinereus – Eucinostomus spp. (D. aureolus – (Eugerres spp. (D. auratus – (D. brevirostris – D. rhombeus)))))]. Therefore, a taxonomic rearrangement is needed. To preserve the monophyly of the group, our proposal is to remove D. aureolus and place it in a new monotypic genus.

The generic diagnosis of Aristocleidus Mueller, 1936 is emended based on a collection of 2 species of the genus from the gills of the Peruvian mojarra, Diapterus peruvianus (Gerreidae), from a lagoon along the Pacifi c Coast of Mexico. The genus is characterized in part by species having a deeply incised base of the ventral anchor with the tip of the superfi cial root conspicuously directed toward that of the deep root. Aristocleidus hastatus Mueller, 1936 is redescribed and Aristocleidus lamothei n. sp. is described from D. peruvianus from the Tres Palos Lagoon, Guerrero State, Mexico. The fi nding of A. hastatus on D. peruvianus in Mexico represents new host and locality records for the species.

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).
