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

Journal 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 ...

Simulated green turtle grazing affects benthic infauna abundance and community composition but not diversity in a Thalassia testudinum seagrass meadow

, 2020
Seagrass meadows host diverse invertebrate faunal communities. Infaunal organisms residing in the sediments of meadows play important roles in the functioning of these ecosystems, such as the breakdown of organic matter.

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

Ecology 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 ...

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

Restoration 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 ...

Micobiota endófita de Thalassia testudinum König en el Caribe colombiano

Boletín 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.

How much seagrass does a dugong need? Metabolic rate of live wild dugongs, Dugong dugon, determined through indirect calorimetry (oxygen consumption)

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract Deterioration of seagrass beds worldwide has raised concern about the future of dugongs because almost all aspects of their life history depend on availability of seagrass. Understanding their energy metabolism and consequently how much seagrass they need will inform protective conservation strategies for dugongs. This study determined resting
