Análisis de la contribución de los sistemas silvopastoriles a la conservación de la flora y fauna en tres comunidades de la reserva de biósfera Bosawás

El estudio se realizó en tres comunidades del Territorio Miskitu Indian Tasbaika Kum, Reserva de Biósfera BOSAWAS (Shiminka, Boca de Plis y Esperanza), para describir la interacción entre especies de flora y avifauna y su influencia en la conservación de estas especies en las áreas de pastoreo, a partir de tres criterios: 1) cuantificar flora y avifauna, 2) prácticas de manejo tradicional, 3) estimar beneficios económico generado por sistemas de pastoreo. Se establecieron tres puntos de conteo dentro de transeptos para avifauna, se estableció parcelas para muestreo de la vegetación en cada comunidad, se seleccionó una comunidad beneficiada por subproyectos del Proyecto Corazón (MARENA) y dos áreas clasificadas como bosque secundario. Para evaluar el beneficio económi co se aplicó entrevistas abiertas y estructuradas dirigida a propietarios de ganado, para documentar los principales beneficios tangibles e intangibles que la población obtiene de estos agrosistemas. El análisis de resultados se determinó en base a índices de diversidad, dominancia, equidad y similitud; tomando en cuenta la riqueza, abundancia y densidad de especies. Se encontró que para flora Shiminka obtuvo los mayores valores de dominancia lo que indica que se encuentran especies de mayor importancia, Esperanza tiene mayor equidad y diversidad, en Shiminka y Esperanza se necesitan mayores estudios, el análisis de Clúster arrojó que aunque existe alguna concordancia entre Boca de Plis y Shiminka, las tres difieren entre sí y el mismo resultado se encontró para la avifauna; y para fauna mayor equidad en Shiminka y Esperanza, mientras la más diversa resultó Esperanza. La similitud establece que Boca de Plis y Esperanza necesitan mayor intensidad de muestreo.

Marine flora and fauna of the Eastern United States Anthozoa: Acitniaria, Corallimorpharia, Ceriantharia, and Zoanthidea

This key includes 60 species of sea anemones and their relatives in the orders Actiniaria, Corallimorpharia, Ceriantharia, and Zoanthidea. Species from the intertidal zone, continental slope, and deep sea are included over a geographic range from Atlantic Canada to approximately South Carolina. In addition to the illustrated key itself, characteristics of each species are summarized in tabular form, including morphology, distribution, and types and sizes of cnidae. Ecological and taxonomic information on each species are also included in an annotated species list. (PDF file contains 76 pages.)

Marine Flora and Fauna of the eastern United States: Acanthocephala

The phylum Acanthocephala (intestinal worm parasites of vertebrates) of the Atlantic coast of the United States comprises 43 species and 20 genera belonging to three orders: Echinorhynchida, Neoechinorhynchida, and Polymorphida. Adults are exclusively intestinal parasites of vertebrates. This study includes those species found in vertebrates of marine and estuarine environments along the North American Atlantic coast between Maine and Texas. Species that can be found within that geographical range and those that typically infect freshwater fishes but that are occasionally present in marine or estuarine hosts are also included. The taxonamy, anatomy, natural history, and ecology of the phylum Acanthocephala are discussed, and an illustrated key to the genera is presented. Techniques, an annotated systematic treatment of all 43 species, and a systematic index are included. No systematic decisions will be made at this time, but areas where such decisions are pending will be indicated and discussed for future reports. (PDF file contains 32 pages.)

Marine Flora and Fauna of the Eastern United States: Dicyemida

This manual treats the six species of dicyemid mesozoans that have been reported in three species of hosts (Octopus vulgaris, O. joubini, and O. briareus) from the eastern coast of North America and the Gulf of Mexico, including the Florida Keys. All are parasites of species of Octopus and are in the genus Dicyema, family Dicyemidae. In the introduction, the life cycle, as known, and the general morphology of dicyemids are briefly described, and methods are given for collecting and preparing material for study. These are followed by a key to species and by an annotated checklist, which includes data, some hitherto unpublished, on their known prevalence in hosts from various localities including Bimini and Bermuda.(PDF file contains 20 pages.)

Marine Flora and Fauna of the Northeastern United States: Erect Bryozoa

Forty-nine species of erect Bryozoa from a broad range of Cyclostome, Ctenostome, and Cheilostome families are described and illustrated, and an artificial dichotomous key is provided for their identification. In general, the marine bryozoan faunas of the northeastern coasts of the United States are poorly known; species records are sparse and voucher collections few, and it is certain that many more species occur in this region than are presently known. The species described here occur in intertidal, coastal or offshore habitats; some are well known and have been recorded on numerous previous occasions, others have been only rarely reported, while a few are known to occur commonly in the north of the region but have yet to be recorded south of Cape Cod. Some of the species described have not been recorded at all on northeastern coasts of the United States, but are widely distributed in North Atlantic continental shelf habitats and perhaps occur in similar parts of the outer shelf of this region. This fauna is thus provisional, but is intended to stimulate further work on the Bryozoa. (PDF file contains 52 pages.)

Marine Flora and Fauna of the Eastern United States: Copepoda, Cyclopoida: Archinotodelphyidae, Notodelphyidae, and Ascidicolidae

This manual includes an introduction to the general biology, a selected bibliography, and an illustrated key to 11 genera and 17 species of copepods of the Crustacea, Subclass Copepoda, Order Cyclopoida, Families Archinotodelphyidae, Notodelphyidae and Ascidicolidae, associated with ascidians from the Atlantic Coast of the United States. Species distributed from the Gulf of Maine to Long Island Sound are emphasized. An annotated systematic list, with statements of the world distribution and new records of association with hosts, and a systematic index are also provided. (PDF file contains 44 pages.)

Marine Flora and Fauna of the Northeastern United States Echinodermata: Crinoidea

The crinoid fauna of the continental margin (0-1500 m) of northeastern North America (Georgia to Canada) includes 14 species in 13 genera and 5 families. We introduce the external morphology and natural history of crinoids and include a glossary of terms, an illustrated key to local taxa, annotated systematic list, and an index. The fauna includes 2 species found no further south than New England and 8 that occur no further north than the Carolinas and Blake Plateau. Comactinia meridionalis (Agassiz) is the only species commonly found in shallow water «50 m). No taxa are endemic to the area. (PDF file contains 34 pages.)

Marine flora and fauna of the eastern United States Mollusca: Cephalopoda

The cephalopods found in neritic waters of the northeastern United States include myopsid and oegopsid squids, sepiolid squids, and octopods. A key with diagnostic illustrations is provided to aid in identification of the eleven species common in the neritic waters between Cape Hatteras and Nova Scotia; included also is information on two oceanic species that occur over the continental shelf in this area and that can be confused with similar-looking neritic species. Other sections comprise a glossary of taxonomic characters used for identification of these species, an annotated systematic checklist, and checklists of the 89 other oceanic species and 18 Carolinian and subtropical neritic species that might occur occasionally off the northeastern United States.
