Contreras-Sánchez ([email protected]) ABSTRACT. The freshwater drum Aplodinotus grunniens is a species widely distributed in North America. In the Mexican southeast, this species occurs in the Usumacinta River, where it supports an artisanal fishery. In this regard, the present study was conducted to supply detailed information on the female reproductive cycle of this species. Calculations of gonadosomatic (GSI) and hepatosomatic (HSI) indexes, histological and visual staging of ovaries as well as the staging of oocyte development were applied together to determine the reproductive changes during an annual cycle. The histological analysis revealed the presence of spawning capable females throughout the year, and the distribution frequencies of oocyte diameters displayed the continuous occurrence of mature -

The isolation of South America from Central America and Africa during the Tertiary Period left a strong imprint on the biota of the Neotropics. For almost 100 million years Neotropical flora, fauna and microorganisms evolved in completely isolation. The emergence of a continuous land bridge, 3 Ma years ago, between Central and South America is well documented and is demonstrated by the arrival of temperate elements in South American highlands and concurrent appearance of South American taxa in Central America. There is strong evidence of displacement of the Neotropical fauna, especially mammals, by northern immigrants, but the same is not observed in relation to plants. -

Darwin and Ichthyology Xvii Darwin’ S Fishes: a Dry Run Xxiii
Darwin’s Fishes An Encyclopedia of Ichthyology, Ecology, and Evolution In Darwin’s Fishes, Daniel Pauly presents a unique encyclopedia of ichthyology, ecology, and evolution, based upon everything that Charles Darwin ever wrote about fish. Entries are arranged alphabetically and can be about, for example, a particular fish taxon, an anatomical part, a chemical substance, a scientist, a place, or an evolutionary or ecological concept. Readers can start wherever they like and are then led by a series of cross-references on a fascinating voyage of interconnected entries, each indirectly or directly connected with original writings from Darwin himself. Along the way, the reader is offered interpretation of the historical material put in the context of both Darwin’s time and that of contemporary biology and ecology. This book is intended for anyone interested in fishes, the work of Charles Darwin, evolutionary biology and ecology, and natural history in general. DANIEL PAULY is the Director of the Fisheries Centre, University of British Columbia, Vancouver, Canada. He has authored over 500 articles, books and papers.

Although we think that the establishment of any conservation policies along the vast coastline of Chile must be based on a multitude of approaches and considerations, scientific, biological, and ecological principles should guide much of these efforts.
