In this PhD thesis five genera of northern Neotropical sea catfish (Ariidae), a marine teleost lineage that repeatedly adapted to freshwater habitats, was investigated with regard to shape changes in relation to macrohabitat transition. An underlying fundamental assumption is that many morphological changes are adaptive in nature and it was examined here whether similar morphological changes occurred with each freshwater transition. Two skeletal features, the opercle bone, that has been shown to be a good marker for habitat adaptation in teleost fishes, and the skull, a commonly used marker for habitat adaptation in terrestrial vertebrates, were investigated applying 2D and 3D geometric morphometrics, respectively. The resulting shape data was analysed using phylogenetically informed multivariate statistics. The application of a mitochondrial DNA marker helped to verify species identities. The distribution of the investigated group makes it a rich subject to address the fundamental question on faunal evolution in the northern Neotropics. Another section of this thesis concerns the investigation of the dating of lineage splitting events among Caribbean and Eastern Pacific ariid species, solving questions on the taxonomy and phylogeny of the group but also testing conflicting hypotheses on the timing of the rise of the Panamanian Isthmus. To do so, a novel approach using Bayesian divergence time estimation was developed that constructs time-calibrated phylogenetic hypotheses from single-nucleotide polymorphisms and fossils for internal-node calibration. In the course of this study new species and freshwater populations of brackish/marine species were found and partially validated by mtDNA, nuclear DNA, or shape analysis, or all of the above together. Comprehensive morphometric analyses showed that habitat has a larger effect on opercle shape than on skull shape, but phylogenetic relationships largely determine the position of species in morphospace for both features. Freshwater species occupy a smaller area in morphospace than brackish and marine species. The Bayesian divergence time estimation revealed that most lineage splitting events among species from the two oceans happened during the Miocene, thus supporting findings for a longer and more complex formation history of the Panamanian Isthmus. 10 Zusammenfassung 11 Zusammenfassung Während der Evolution der echten Knochenfische (Teleostei) kam es häufig zu Transitionen zwischen den Makrohabitaten Salz- und Süßwasser. In der vorliegenden Doktorarbeit wurden fünf Gattungen der im salzwasserlebenden Ariidae (Kreuzwelse) aus den nördlichen Neotropen untersucht. Sie zeichnen sich dadurch aus, dass Mitglieder der einzelnen Gattungen sich wiederholt an Süßwasserhabitate angepasst haben. Die zugrundeliegende Hypothese ist, dass a) Formveränderungen der jeweiligen Art auf Grund von Anpassung an das neue Habitat auftreten können, und b) im gleichen Habitat die immer gleiche Form begünstigt werden könnte. Zwei Kapitel der vorliegenden Arbeit befassen sich mit den Formveränderungen,

Based on a specimen from Casaya Island in Panama’s Las Perlas archipelago, they named the first new species, Jimenez’s Sea Catfish, Ariopsis jimenzi for Máximo Jiménez Acosta, a zooarchaeology technician in archaeologist Richard Cooke’s lab at the Smithsonian Tropical Research Institute. Jiménez drew attention to the possible existence of a new species based on his examination of bone characteristics in specimens formerly originally believed to be A. seemanni, or the Colombian shark catfish. His observation that the bones belonged to a new species was immediately confirmed by molecular analysis. The second new species was named the New Granada sea catfish, Ariopsis canteri, for Diego Canter Ríos (1984-2007), a young and talented Colombian ichthyologist who died in a traffic accident near Santa Marta, Colombia along with three other biology undergraduates. He collected the data on the new species and also worked on this group of catfish for part of his bachelor’s thesis in marine biology. The zoologists in the team — Alexandre Marceniuk from Brazil’s Museu Paraense Emílio Goeldi; Arturo Acero of the Universidad Nacional de Colombia, and Ricardo Betancur of the University of Puerto Rico — constructed a family tree showing how the eight different species in the genus Ariopsis are related.

An updated checklist and characterisation of the ichthyofauna (Elasmobranchii and Actinopterygii) of the Laguna de Tamiahua, Veracruz, Mexico. Acta Ichthyol. Piscat. 48 (4): 341–362. Background. Laguna de Tamiahua is ecologically and economically important as a nursery area that favours the recruitment of species that sustain traditional fisheries. It has been studied previously, though not throughout its whole area, and considering the variety of habitats that sustain these fisheries, as well as an increase in population growth that impacts the system. The objectives of this study were to present an updated list of fish species, data on special status, new records, commercial importance, dominance, density, ecotic position, and the spatial and temporal distribution of species in the lagoon, together with a comparison of Tamiahua with 14 other Gulf of Mexico lagoons. Materials and methods. Fish were collected in August and December 1996 with a Renfro beam net and an otter trawl from different habitats throughout the lagoon. The species were identified, classified in relation to special status, new records, commercial importance, density, dominance, ecotic position, and spatial distribution patterns.

    THE SOUTH AMERICAN NEMATOGNATHI OF THE MUSEUMS AT LEIDEN AND AMSTERDAM by J. W. B. VAN DER STIQCHEL (Museum voor het OnderwSs, 's-Gravenhage) The collections of the South American Nematognathi in the Rijksmuseum van Natuurlijke Historie at Leiden, referred to in this publication as "Mu• seum Leiden", and of those in the Zoologisch Museum at Amsterdam, referred to as "Museum Amsterdam", consist of valuable material, which for a very important part has not been studied yet. I feel very much obliged to Prof. Dr. H. Boschma who allowed me to start with the study of the Leiden collections and whom I offer here my sincere thanks. At the same time I want to express my gratitude towards Prof. Dr. L. F. de Beaufort, who has been so kind to place the collection of the Zoological Museum at Amsterdam at my disposal. Furthermore I am greatly indebted to Dr. F. P. Koumans at Leiden for his assistance and advice to solve the various problems which I met during my study. The material dealt with here comes from a large number of collections of different collectors, from various areas of South America, it consists of 125 species, belonging to 14 families of the order Nematognathi. Contrary to the original expectations no adequate number of specimens from Surinam could be obtained to get a sufficient opinion about the occurrence of the various species, and, if possible, also about their distribution in this tropical American part of the Netherlands. On the whole the collections from Surinam were limited to the generally known species only.

    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.
