Abstract:

Pseudoplatystoma fasciatum represents one of the most important items in the continental fisheries of Venezuela. The great fishing pressure exerted on this species has decimated the populations in the Orinoco River Delta and other regions of the country. The current condition of the population in the delta region is unknown and information about basic biological parameters is unavailable. Hence, population and reproductive parameters of this catfish were determined in this region. Results showed that the size interval was from 30 to 105 cm total length (TL), generally smaller than the size ran

Abstract:

We present Orinoco, an open-source Python toolkit that applies the fast-marching method to derive a river delta channel network from a water mask and ocean delineation. We are able to estimate flow direction, along-channel distance, channel width, and network-related metrics for deltaic analyses including the steady-state fluxes. To demonstrate the capabilities of the toolkit, we apply our software to the Wax Lake and Atchafalaya River Deltas using water masks derived from Open Street Map (OSM) and Google Maps. We validate our width estimates using the Global River Width from Landsat (GRWL) da

ABSTRACT Icehouse continental-shelf-margin accretion is typically driven by high-sediment-supply deltas and repeated glacio-eustatic, climate-driven sea-level changes on a ca. 100 ky time scale. The paleo–Orinoco margin is no exception to this, as the paleo–Orinoco River Delta with its high sediment load prograded across Venezuela, then into the Southern and Columbus basins of Trinidad since the late Miocene, depositing a continental-margin sedimentary prism that is &gt; 12 km thick, 200 km wide, and 500 km along dip.

Abstract:

Beginning in 1661, the Jesuits conducted missionary activity in the Orinoquia [the Orinoco delta]. Among the more significant challenges was the introduction of literacy to a people whose concepts of history and society were quite foreign to Spanish and Italian priests. Creating Christians would therefore entail creating a literate culture: the Jesuits began by learning local traditions and committing these to paper, and only then teaching the children of the region to read and write. While none of these teaching books survive, the missionary schools and houses kept libraries which included vo

This paper addresses the use of greetings and the importance of promises in political speeches performed by Warao and non-Warao indigenous politicians to Warao audiences in the Orinoco Delta, Venezuela.

Promises are important for the Warao because they link political speech with other meaningful events, especially political gift distribution. Promises create trans-semiotic

Abstract:

A small suite of seafloor sediment samples (water depth less than 20 m) was collected in 2005 from the sheltered, logarithmic-spiral Guayaguayare Bay along the SE coast of Trinidad, West Indies. The easternmost shielded part of the bay was then occupied by a meadow of the seagrass Halodule wrightii, the closest seagrass bed to the Boca Grande, the main distributary of the Orinoco Delta. Four foraminiferal taphofacies were distinguished, ascribable to a relict coral reef system: (1) A shallow-water (approx. 5 m) taphofacies dominated by Pararotalia sarmientoi. (2) A back-reef taphofacies (appro

O objetivo deste trabalho foi descrever os aspectos socioambientais que favoreceram o processo de mobilidade praticado pela etnia indígena venezuelana Warao, desde o delta do Orinoco, no nordeste da Venezuela até Manaus, capital do estado do Amazonas, na região norte do Brasil. A metodologia utilizada nesta pesquisa foi a do método dedutivo; quanto aos meios, a pesquisa utilizou-se de produções bibliográficas e documentais; quanto aos fins, a pesquisa foi qualitativa. A conclusão a que se chegou foi a de que o primeiro fator que impulsionou a saída de inúmeros Warao de suas milenares terras fo

Abstract:

SummaryAn assessment of trade in parrots throughout Venezuela, 1988–1989, reveals alarmingly high internal and international levels. The national trade has main outlets in major cities, but is now compounded by the use of feathers for Indian artifacts sold to tourists. International trade involves illegal export chiefly from the Orinoco Delta, the majority of such birds (65,000–75,000) destined for Guyana. The large macaws suffer badly from both types of trade, but owing to its restricted range the endemic Amazona barbadensis is perhaps the most critically threatened species. Other species are
