Biomasa y densidad de dos especies de pastos marinos en el sur de Quintana Roo, México

open access: yesRevista de Biología Tropical, 2000
La biomasa y productividad de una comunidad de pastos marinos es útil para determinar el estado ecológico de la costa. Se comparó la biomasa foliar y la densidad de vainas en praderas de Thalassia testudinum Banks & Sol. ex K. D. Koenig, en dos ambientes

A Comparison of Two Methods for Enhancing the Recovery of Seagrasses into Propellor Scars: Mechanical Injection of a Nutrient and Growth Hormone Solution vs. Defecation by Roosting Seabirds: Final Report. [PDF]

open access: yes, 2000
Based on the recovery rates for Thalassia testudinum measured in this study for scars of these excavation depths and assuming a linear recovery horizon, we estimate that it would take ~ 6.9 years (95% CI. = 5.4 to 9.6 years) for T.

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

open access: yesConservation 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.

Long-Term Effects of Adding Nutrients to an Oligotrophic Coastal Environment [PDF]

open access: yes, 2011
Management of ecological disturbances requires an understanding of the time scale and dynamics of community responses to disturbance events. To characterize long-term seagrass bed responses to nutrient enrichment, we established six study sites in ...

Global Review of Blue Carbon Ecosystem Microbial Communities

open access: yesEnvironmental 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.

Random amplified polymorphic DNA (RAPD) finger prints evidencing high genetic variability among marine angiosperms of India [PDF]

open access: yes, 2016
In India 14 seagrass species can be found with monospecific genera (Enhalus, Thalassia and Syringodium), Cymodocea with two species and Halophila and Halodule represented by more than two taxonomically complex species. Considering this, the present study

Carbon acquisition mechanisms in Halophila johnsonii and Thalassia testudinum

open access: yesAquatic Botany, 2019
Abstract Mechanisms for carbon uptake in the small-bodied Halophila johnsonii and large-bodied Thalassia testudinum were compared using photosynthesis measurements (oxygen flux) with, and without, the extracellular carbonic anhydrase inhibitor acetazolamide (AZ) and TRIS buffer. Our results indicated T. testudinum and H.

Biogeochemical effects of iron availability on primary producers in a shallow marine carbonate environment [PDF]

open access: yes, 2001
We completed a synoptic survey of iron, phosphorus, and sulfur concentrations in shallow marine carbonate sediments from south Florida. Total extracted iron concentrations typically were 50 μmol g-1 dry weight (DW) and tended to decrease away from the ...
