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

Effects of Aquaculture and Thalassia testudinum on Sediment Organic Carbon in Xincun Bay, Hainan Island

Water
Eutrophication due to aquaculture can cause the decline of seagrasses and impact their carbon storage capacity. This study explored the effects of aquaculture on the sediment organic carbon (SOC) in Thalassia testudinum seagrass beds using enzyme ...

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

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

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 ...

A multi-year study of acoustic propagation and ambient sound in a Thalassia testudinum seagrass meadow in a shallow sub-tropical lagoona).

Journal of the Acoustical Society of America
Seagrasses provide a multitude of ecosystem services and act as important carbon sinks. However, seagrass habitats are declining globally, and they are among the most threatened ecosystems on earth.

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.

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.

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.
