Structure of Tropical River Food Webs Revealed by Stable Isotope Ratios
OIKOS 96: 46–55, 2002 Structure of tropical river food webs revealed by stable isotope ratios David B. Jepsen and Kirk O. Winemiller Jepsen, D. B. and Winemiller, K. O. 2002. Structure of tropical river food webs revealed by stable isotope ratios. – Oikos 96: 46–55. Fish assemblages in tropical river food webs are characterized by high taxonomic diversity, diverse foraging modes, omnivory, and an abundance of detritivores. Feeding links are complex and modified by hydrologic seasonality and system productivity. These properties make it difficult to generalize about feeding relation- ships and to identify dominant linkages of energy flow. We analyzed the stable carbon and nitrogen isotope ratios of 276 fishes and other food web components living in four Venezuelan rivers that differed in basal food resources to determine 1) whether fish trophic guilds integrated food resources in a predictable fashion, thereby providing similar trophic resolution as individual species, 2) whether food chain length differed with system productivity, and 3) how omnivory and detritivory influenced trophic structure within these food webs. Fishes were grouped into four trophic guilds (herbivores, detritivores/algivores, omnivores, piscivores) based on literature reports and external morphological characteristics. Results of discriminant function analyses showed that isotope data were effective at reclassifying individual fish into their pre-identified trophic category. Nutrient-poor, black-water rivers showed greater compartmentalization in isotope values than more productive rivers, leading to greater reclassification success. In three out of four food webs, omnivores were more often misclassified than other trophic groups, reflecting the diverse food sources they assimilated. When fish d15N values were used to estimate species position in the trophic hierarchy, top piscivores in nutrient-poor rivers had higher trophic positions than those in more productive rivers. -
Phylogenetic Relationships of the South American Doradoidea (Ostariophysi: Siluriformes)
Neotropical Ichthyology, 12(3): 451-564, 2014 Copyright © 2014 Sociedade Brasileira de Ictiologia DOI: 10.1590/1982-0224-20120027 Phylogenetic relationships of the South American Doradoidea (Ostariophysi: Siluriformes) José L. O. Birindelli A phylogenetic analysis based on 311 morphological characters is presented for most species of the Doradidae, all genera of the Auchenipteridae, and representatives of 16 other catfish families. The hypothesis that was derived from the six most parsimonious trees support the monophyly of the South American Doradoidea (Doradidae plus Auchenipteridae), as well as the monophyly of the clade Doradoidea plus the African Mochokidae. In addition, the clade with Sisoroidea plus Aspredinidae was considered sister to Doradoidea plus Mochokidae. Within the Auchenipteridae, the results support the monophyly of the Centromochlinae and Auchenipterinae. The latter is composed of Tocantinsia, and four monophyletic units, two small with Asterophysus and Liosomadoras, and Pseudotatia and Pseudauchenipterus, respectively, and two large ones with the remaining genera. Within the Doradidae, parsimony analysis recovered Wertheimeria as sister to Kalyptodoras, composing a clade sister to all remaining doradids, which include Franciscodoras and two monophyletic groups: Astrodoradinae (plus Acanthodoras and Agamyxis) and Doradinae (new arrangement). Wertheimerinae, new subfamily, is described for Kalyptodoras and Wertheimeria. Doradinae is corroborated as monophyletic and composed of four groups, one including Centrochir and Platydoras, the other with the large-size species of doradids (except Oxydoras), another with Orinocodoras, Rhinodoras, and Rhynchodoras, and another with Oxydoras plus all the fimbriate-barbel doradids. Based on the results, the species of Opsodoras are included in Hemidoras; and Tenellus, new genus, is described to include Nemadoras trimaculatus, N. -

About the Book the Format Acknowledgments
About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization. -
Rotifer Species Diversity in Mexico: an Updated Checklist
diversity Review Rotifer Species Diversity in Mexico: An Updated Checklist S. S. S. Sarma 1,* , Marco Antonio Jiménez-Santos 2 and S. Nandini 1 1 Laboratory of Aquatic Zoology, FES Iztacala, National Autonomous University of Mexico, Av. de Los Barrios No. 1, Tlalnepantla 54090, Mexico; [email protected] 2 Posgrado en Ciencias del Mar y Limnología, Universidad Nacional Autónoma de México, Ciudad Universitaria, Mexico City 04510, Mexico; [email protected] * Correspondence: [email protected]; Tel.: +52-55-56231256 Abstract: A review of the Mexican rotifer species diversity is presented here. To date, 402 species of rotifers have been recorded from Mexico, besides a few infraspecific taxa such as subspecies and varieties. The rotifers from Mexico represent 27 families and 75 genera. Molecular analysis showed about 20 cryptic taxa from species complexes. The genera Lecane, Trichocerca, Brachionus, Lepadella, Cephalodella, Keratella, Ptygura, and Notommata accounted for more than 50% of all species recorded from the Mexican territory. The diversity of rotifers from the different states of Mexico was highly heterogeneous. Only five federal entities (the State of Mexico, Michoacán, Veracruz, Mexico City, Aguascalientes, and Quintana Roo) had more than 100 species. Extrapolation of rotifer species recorded from Mexico indicated the possible occurrence of more than 600 species in Mexican water bodies, hence more sampling effort is needed. In the current review, we also comment on the importance of seasonal sampling in enhancing the species richness and detecting exotic rotifer taxa in Mexico.

Recent discoveries of numerous 25 morphologically diverse lungfish tooth plates from southern Scotland and northern England indicate 26 that at least ten dipnoan taxa existed during the earliest Carboniferous. Of these taxa, only two, 27 Xylognathus and Ballgadus, preserve cranial and post-cranial skeletal elements that are yet to be 28 described. Here we present a description of the skull of a new genus and species of lungfish, 29 Limanichthys fraseri gen. -

New Materials on Ventalepis Ketleriensis Schultze, 1980 Extend the Zoogeographic Area of a Late Devonian Vertebrate Assemblage
Acta Geologica Polonica, Vol. 68 (2018), No. 3, pp. 437–454 DOI: 10.1515/agp-2018-0023 New materials on Ventalepis ketleriensis Schultze, 1980 extend the zoogeographic area of a Late Devonian vertebrate assemblage OLEG LEBEDEV1 and ERVĪNS LUKŠEVIČS2 1 Palaeontological Institute of Russian Academy of Sciences, 123 Profsoyuznaya Street, Moscow, 117997, Russia. E-mail: [email protected] 2 Department of Geology, University of Latvia, Raiņa Boulevard 19, Riga, LV-1586, Latvia. E-mail: [email protected] ABSTRACT: Lebedev, O. and Lukševičs, E. 2018. New materials on Ventalepis ketleriensis Schultze, 1980 extend the zoogeo- graphic area of a Late Devonian vertebrate assemblage. Acta Geologica Polonica, 68 (3), 437−454. Warszawa. Newly collected and restudied earlier materials on an enigmatic fish Ventalepis ketleriensis Schultze, 1980 from the upper Famennian (postera – ? Lower expansa conodont zones) of Latvia and central and northwestern Russia support its porolepiform affinities. A new family Ventalepididae fam. nova is established for this genus upon a peculiar combination of characters, including scale structure and dermal bones ornamentation. New records extend the distribution of this genus and the Ventalepis vertebrate assemblage on the whole to a vast geographical zone along the south-eastern coast of the Old Red Sandstone continent. The habitat area of the Devonian vertebrate assemblage over such a large territory within the zoogeographical province of Baltica is established for the first time. Palaeozoogeographical analysis suggests Laurentian affinities of the Ventalepis assemblage demonstrating the major congruency to the Belgian and East Greenland ones. These and Russian localities are separated by a vast ORS continent. Presence of the dipnoan Jarvikia in all three locations, as well as an Ichthyostega-like tetrapod in the Belgian one reveals palaeozoogeographical connections, which might reflect possible dwelling not only in the near-shore continent periphery but also in the river systems of the continent itself.
