Testing biodegradable interventions to disrupt plant–animal feedbacks and promote seagrass establishment

Restoration Ecology, Volume 34, Issue 1, January 2026.
Biogeochemical and physical feedbacks are well known to prevent ecosystem recovery even after initial disturbance factors are mitigated. However, multi‐trophic interactions that may maintain disturbed areas have received less attention, despite their potential importance in mediating restoration success. In this study, we surveyed stingray feeding pits

Subtropical seagrass epiphytes: Nitrogen fixation rates align with Crocosphaera‐like cyanobacteria abundances

Limnology and Oceanography, Volume 70, Issue 12, Page 3958-3971, December 2025.
Abstract Nitrogen fixers can enhance nitrogen availability for seagrass communities that may be nitrogen limited. However, the role of epiphytic diazotrophs, particularly cyanobacteria, in seagrass communities is not well understood. We measured nitrogen fixation rates, epiphyte biomass, and relative abundances of epiphytic diazotrophs on the leaves of

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

Revista 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

Up, Down, and All Around: Courtship Behavior Deviants and Genetic Divergence in the Reef‐Dwelling Bioluminescent Ostracod, Photeros annecohenae (Myodocopida: Cypridinidae)

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Species that have complex courtship behaviors are some of the most evolutionarily diverse lineages observed in nature. Here, we quantify differences in the courtship behavior, morphology, and genetics of a group of bioluminescent marine ostracod residents of the Mesoamerican barrier reef of Belize.

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

Contrasting effects of rhizosphere and sediment microbiota on seagrass performance in response to a simulated marine heatwave

Journal of Ecology, Volume 113, Issue 9, Page 2429-2446, September 2025.
We experimentally disrupted below‐ground microbial communities to test their role in the growth and survival of the seagrass Zostera muelleri under two marine heatwave scenarios. Seagrass leaf growth declined with rhizosphere microbiome disruption across all temperature and sediment conditions.

Carbon acquisition mechanisms in Halophila johnsonii and Thalassia testudinum

Aquatic 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.

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.
