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

Recruitment of Thalassia testudinum seedlings into physically disturbed seagrass beds [PDF]

Marine Ecology Progress Series, 2004
Thalassia testudinum seedling recruitment, survival, and growth were examined within physically disturbed seagrass beds in the Florida Keys. Two separate studies were conducted. In the first, a large-scale study, T. testudinum seedlings were surveyed and collected from a large seagrass disturbance (1560 m 2 ), 4.8 yr after the initial impact from a ...

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.

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.

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 in populations of the seagrass thalassia testudinum in rabbit key basin, Florida bay

, 1998
Levels of clonal diversity within the seagrass Thalassia testudinum Banks ex Kӧnig have been predicted to be low. This species has historically been perceived as relying on vegetative propagation for growth and extension of meadows, the role of sexual ...

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
