Web 2.0 Y Medios Sociales Para El Desarrollo En Pesca Y Acuicultura. En Ruta Hacia Las Redes Sociales, ¿Cuál Puede Ser Un Itinerario De Puesta En Marcha?, Enrique Wulff
Enrique Wulff
El modelo usado por la antigua red, en base a carpetas compartidas y repositorios, para desarrollar nuevos contenidos y transmitirlos se agota. En éste libro se propone recordar que si nadie visita tu página, que si uno se limita a hablar de si mismo sin formular preguntas, que si por el contrario facilita respuestas y las promociona construyendo algo excitante, si establece objetivos trimestrales, y si siempre tiene un horizonte a largo término. Entonces accede a las nuevas y fáciles de usar herramientas que se conocen como Web 2.0, las cuales conectan gente dando lugar a redes sociales, colaborando y …
Wintering Ecology Of Adult North American Ospreys, Brian E. Washburn, Charles J. Henny, Mark S. Martell, Richard O. Bierregaard, Brian S. Dorr, Thomas J. Olexa
Wintering Ecology Of Adult North American Ospreys, Brian E. Washburn, Charles J. Henny, Mark S. Martell, Richard O. Bierregaard, Brian S. Dorr, Thomas J. Olexa

North American Ospreys (Pandion haliaetus) typically migrate long distances to their wintering grounds in the tropics. Beyond the general distribution of their wintering range (i.e., the Caribbean, South America, and Central America), very little is known about the wintering ecology of these birds. We used satellite telemetry to determine the duration of wintering period, to examine the characteristics of wintering areas used by Ospreys, and to quantify space use and activity patterns of wintering Ospreys. Adult Ospreys migrated to wintering sites and exhibited high wintering site fidelity among years. Overall, Ospreys wintered on river systems (50.6%) more than on lakes …
Geographic Segregation And Evidence Of Density-Dependent Changes In Sex Ratios In An Abundant Colonial Waterbird, Brian S. Dorr, Katie C. Hanson-Dorr, Travis L. Devault, Alban Guillaumet, Scott C. Barras
Geographic Segregation And Evidence Of Density-Dependent Changes In Sex Ratios In An Abundant Colonial Waterbird, Brian S. Dorr, Katie C. Hanson-Dorr, Travis L. Devault, Alban Guillaumet, Scott C. Barras
Brian S Dorr
Demographic information, such as geographic segregation of sexes and sex ratio data, is needed to develop, model and evaluate conservation and management strategies for wildlife. A variety of physiological, behavioral and environmental factors can influence segregation of sexes and sex ratios, many of which originate with density- dependent processes. Departure from 50:50 sex ratios of double-crested cormorants (Phalacrocorax auritus) collected during control efforts in breeding and wintering areas across their eastern range of the USA were evaluated using using a Z-test as well as Stouffer’s weighted Z-tests. In addition, a specifically-designed randomization test was used to evaluate density-dependent effects on …
Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra
Management Regimes And Its Impact On The Wetland Fisheries Management In Assam, Ganesh Chandra
Ganesh Chandra
Assam is endowed with copious aquatic wealth in the form of beels, swamps, ponds and rivers. The floodplain wetlands (beels) extending over one lakh hectare, constitute the most important fishery resource of the state. The beels are considered as one of the most productive ecosystems owing to their characteristic interactions between land and water system. These wetlands are the common property resource and under different management regimes. These wetlands are under various management regimes, i.e., private management (individuals and groups), fishermen cooperative management, Community-based fisheries management (decentralized management, Government works as facilitator) and open access. Most of the unregistered beels …
Population Dynamics Of Spiders In Ayya Nadar Janaki Ammal College Campus, Sivakasi, Virudhunagar District, Tamil Nadu, India, Jeyaparvathi S
Population Dynamics Of Spiders In Ayya Nadar Janaki Ammal College Campus, Sivakasi, Virudhunagar District, Tamil Nadu, India, Jeyaparvathi S
JOZS JOURNAL
Spiders play an important role in regulating insect pests in the agricultural ecosystem. There are a large number of species, many of them with high population densities. A survey was conducted in the Ayya Nadar Janaki Ammal College campus from January, 2011 - March, 2011. 29 individuals were collected representing 11 families and 21 genera. From these, 25 species were present throughout the campus; however, only 5 of these were taken in the ground, they are the ground dwellers. Peucetia viridana (Stolizcka), Oxyopes hindostanicus (Tikader), Lycosa pseudoannulata (Bosenberg) and Plexippus petersi, were common. P. viridana was the dominant species followed …
