Caribbean-wide, long-term study of seagrass beds reveals local variations, shifts in community structure and occasional collapse.

PLoS ONE, 2014
The CARICOMP monitoring network gathered standardized data from 52 seagrass sampling stations at 22 sites (mostly Thalassia testudinum-dominated beds in reef systems) across the Wider Caribbean twice a year over the period 1993 to 2007 (and in some cases

A New Conceptual Model of Tropical Seagrass Eutrophication: Evidence for Single Nutrient Management

Conservation Letters, Volume 18, Issue 5, September/October 2025.
ABSTRACT Nutrient enrichment is one of the greatest threats to seagrass ecosystems globally. Current management is based on a temperate conceptual model of seagrass eutrophication where epiphytes and then phytoplankton cause light limitation and seagrass die‐off.

Clonal Diversity and Connectedness of Turtle Grass (Thalassia Testudinum) Populations in a UNESCO Biosphere Reserve [PDF]

, 2015
John, American Virgin Island turtlegrass are not clonal populations. John\u27s populations have high connectivity to each other. We assessed Thalassia testudinum population genetics among four bays in St.

Global Review of Blue Carbon Ecosystem Microbial Communities

Environmental Microbiology, Volume 27, Issue 8, August 2025.
A thorough review of Blue Carbon Ecosystems' global and regional patterns in microbial diversity, functions, and distribution is currently missing. In this study, we have, for the first time, analysed 70 years (1930–2020) of data on archaeal, bacterial, and fungal diversity and reported functions in mangrove, saltmarsh, and seagrass ecosystems.

ESTIMACIÓN DE LA BIOMASA DE THALASSIA TESTUDINUM A PARTIR DE DATOS DE BIOMASA HÚMEDA/ Estimation of Thalassia testudinum dry biomass from wet biomass data

Revista de Investigaciones Marinas, 2014
La biomasa seca del macrofitobentos se emplea para analizar la abundancia, productividad y otros procesos que se producen en los ecosistemas. Pero el secado de la biomasa implica la destrucción del especimen, así como consumo de tiempo, electricidad.

Metacystis borrori n. sp (Ciliophora : Metacystidae) on the Seagrass Thalassia testudinum

, 2003
A new epibiontic ciliate of the genus Metacystis is described on the seagrass Thalassia testudinum of the coral reef lagoons of Veracruz, Mexico. The ciliate was studied in living and stained specimens and under the scanning electron microscope. The cell

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

Revista 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.

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 ...

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 ...
