Comparing Cloud Mask Products for Seagrass Mapping Over Sentinel‐2 Imagery: Toward a First National Seagrass Map for Venezuela

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Despite providing many valuable ecosystem services, seagrasses are a threatened habitat and their global distribution is not fully known. For example, Venezuela lacks a national seagrass map. An established regional mapping approach for seagrass exists for the Google Earth Engine (GEE) platform, but requires a long time window to obtain ...

Micobiota endófita de Thalassia testudinum König en el Caribe colombiano

open access: yesBoletín de Investigaciones Marinas y Costeras, 2023
Se evaluó la presencia de hongos endófitos en hojas de Thalassia testudinum a través del secuenciamiento de la región ITS encontrando abundancias de Ascomicetos (35,9 %), Basidiomicetos (2,9 %) y un alto porcentaje (60 %) de secuencias no clasificadas dada la limitada base de datos existentes.

Going With the Flow? Relative Importance of Riverine Hydrologic Connectivity Versus Tidal Influence for Spatial Structure of Genetic Diversity and Relatedness in a Foundational Submersed Aquatic Plant

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
We assessed genotypic and genetic diversity in the submersed aquatic plant species Vallisneria americana in the Potomac River, USA, to understand how riverine hydrologic connectivity and tidal regime affected spatial genetic structure. We found striking differences in the structure of diversity, clonal growth, and relatedness in different tidal ...

Polychaeta (Annelida) associated with Thalassia testudinum in the northeastern coastal waters of Venezuela

open access: yesRevista de Biología Tropical, 2006
Seasonal variations of polychaetes in a Thalassia testudinum bed were studied from June 2000 to April 2001 in Chacopata, northeastern Venezuela. Eight replicate samples were taken monthly with a 15 cm diameter core and the sediment was passed through a 0.

High species richness of epiphytic Mastogloia (Mastogloiales: Bacillariophyceae) on Thalassia testudinum along the coast of Campeche, southern Gulf of Mexico

open access: yesRevista Mexicana de Biodiversidad, 2020
Diatoms of the genus Mastogloia are naviculoid forms that are generally easy to discriminate due to the presence of marginal chambers known as partecta.

Employing invertebrates to restore herbivory on Caribbean coral reefs: recent developments and remaining barriers

open access: yesRestoration Ecology, Volume 33, Issue 4, May 2025.
With coral reefs in global decline and further threatened by growing anthropogenic impacts, effective strategies for restoring these critical ecosystems are increasingly sought after. In Caribbean reefs, where disease outbreaks and fishing pressure have reduced herbivore abundances and facilitated widespread phase shifts from coral to algal dominance ...

Is light involved in the vertical growth response of seagrasses when buried by sand? [PDF]

open access: yes, 1997
5 pages, 3 figures.Involvement of light in the vertical growth response of Cymodocea nodosa (Ucria) Ascherson seedlings to sand burial was tested by comparing the growth response of seedlings that were buried and seedlings that were buried but had the ...

Simulated herbivory and the dynamics of disease in Thalassia testudinum [PDF]

open access: yesMarine Ecology Progress Series, 2004
An experiment was conducted in a Thalassia testudinum bed in SW Florida to examine the effect of simulated green turtle Chelonia mydas L. herbivory on the intensity of infection by Labyrinthula, which causes wasting disease in seagrass. Four pairs of 4.0 m 2 plots were established at the site, with each pair containing one plot subjected to simulated ...
