Changes in seagrass species composition in northwestern Gulf of Mexico estuaries: effects on associated seagrass fauna.

PLoS ONE, 2014
The objective of this study was to measure the communities associated with different seagrass species to predict how shifts in seagrass species composition may affect associated fauna.

Explaining the divergence of population trajectories for two interacting waterfowl species

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Identifying the specific environmental features and associated density‐dependent processes that limit population growth is central to both ecology and conservation. Comparative assessments of sympatric species allow for inference about how ecologically similar species differentially respond to their shared environment, which can be used to ...

Fluxes of zooplankton biomass between a tidal estuary and the sea in Northeastern Brazil

Brazilian Journal of Oceanography, 2007
The objective of this study was to quantify the zooplankton biomass transport between the Santa Cruz Channel (SCC) at Catuama north inlet and the adjacent shelf located in Itamaracá estuarine ecosystem, Pernambuco State, Northeastern Brazil. Sampling was

Restored seagrass rapidly provides high‐quality habitat for mobile animals

Restoration Ecology, Volume 33, Issue 1, January 2025.
Restoring seagrasses provides habitat for animals, many of which play vital roles in the maintenance, persistence, and resilience of seagrass habitat. Understanding how the maturity of restored seagrass habitats influences the colonization and condition of associated animal communities can provide insights to inform restoration methods and improve ...

Seasonal variability and seagrass traits affect methane fluxes in a subtropical meadow

Journal of Ecology, Volume 112, Issue 12, Page 2771-2784, December 2024.
These results indicate that within‐species more so than between‐species trait variability drives the direction and magnitude of CH4 fluxes in seagrass meadows. The authors identified a trade‐off where seagrass biomass is often associated with enhanced sediment carbon storage, but in this study, plant size promoted CH4 production, potentially offsetting

Interactive effects of hyposalinity and nitrate loading on growth, physiology, and nitrogen status of the seagrass, Halodule wrightii

Frontiers in Marine Science
The study goal was to examine the interactive physiological effects of two freshwater inflow stressors, nitrate pulses coupled with salinity decrease, on the seagrass Halodule wrightii.

Understanding the drivers of seagrass loss in Kenya: Evidence for the impacts of population and fishing

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 7, July 2024.
Abstract Seagrass ecosystems are crucial for supporting biodiversity and serve as vital fishing grounds. Unfortunately, their cover is declining globally. In Kenya, seagrass cover is falling by ~ 1.6% annually but the causes are unknown. This study investigated the possible anthropogenic drivers of seagrass decline along the Kenyan coastline. Satellite

The distribution of seagrasses in Dominica, Lesser Antilles

Revista de Biología Tropical, 2010
Seagrass beds are the largest organism-built marine habitat in Dominica, yet have only been surveyed since 2007. Standardized examinations along a depth gradient between 0 and 24m, focusing on magnoliophyte species composition and benthic cover of shoots

Community structure of the ichthyofauna associated with seagrass beds ( Halodule wrightii) in Formoso River estuary - Pernambuco, Brazil

Anais da Academia Brasileira de Ciências, 2010
Seagrass beds are used by juvenile fishes in different ways, generally as nursery sites, shelter from predators, reducing competition and increasing availability of food resources, thus establishing a relationship of connectivity with other ecosystems ...

The Global Biogeochemical Cycle of the Rare Earth Elements

Global Biogeochemical Cycles, Volume 38, Issue 6, June 2024.
Abstract To improve our understanding and guide future studies and applications, we review the biogeochemistry of the rare earth elements (REE). The REEs, which form a chemically uniform group due to their nearly identical physicochemical properties, include the lanthanide series elements plus scandium (Sc) and yttrium (Y).
