Comparison of Phenolic and Flavonoid Content and Antioxidant and Chelating Activities of Rhizophora mangle in Different Anthropogenically-Polluted Coastal Lagoons

open access: yesFrontiers in Marine Science, 2022
The production of total phenolic content (TPC) and total flavonoid content (TFC), antioxidant (AA), and copper chelating (CACu+) activities of Rhizophora mangle from three coastal lagoons under different grades of anthropogenic pollution and pollutant ...

Morfofisiología del género Rhizophora en la Reserva Natural Isla Juan Venado, Pacífico de Nicaragua

open access: yesLa Calera, 2022
Los manglares son ecosistemas únicos que crecen en aguas salobres en las fronteras de los litorales tropicales; representan un enorme valor científico, ecológico, económico y cultural.

On the relationship between Photosystem II thermotolerance and irreversible heat damage in leaves of Rhizophora mangle

open access: yesPlant Biology, EarlyView.
Temperature‐F0 fluorescence curves of Rhizophora mangle leaves demonstrate that Tcrit, the temperature at which F0 begins to rise, is unrelated to tissue necrosis; irreversible leaf damage starts to occur at significantly higher temperatures where fluorescence emission is maximal. Abstract Global temperatures are on the rise and may, together with more

Extraordinary methane levels in a small bar‐built tropical estuary

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Small estuaries link uplands and nearshore marine environments but are understudied in many regions. We quantified spatial and temporal variability in CH4, CO2, nutrients, and organic matter in a small, deep, bar‐built tropical estuary in Fajardo, Puerto Rico.

Density Estimates of Endangered Endemic Rodents Suggest Broader Impacts of Invasive Burmese Pythons Following a Category 4 Hurricane in the Florida Keys

open access: yesBiological Diversity, Volume 3, Issue 2, Page 88-98, June 2026.
Density estimates of two endangered rodent subspecies, endemic to Key Largo, Florida, USA. These findings illustrate the contrasting dynamics of two native species associated with the prevalence of invasive Burmese pythons and global change. The woodrats' decline emphasizes its potential risk of extinction as global change continues to impact island ...

Photosynthetic performance of mangroves Rhizophora mangle and Laguncularia racemosa under field conditions Desempenho fotossintético de Rhizophora mangle e Laguncularia racemosa em condições de campo

open access: yesRevista Árvore, 2008
In mature mangrove plants Rhizophora mangle L. and Laguncularia racemosa Gaerth. growing under field conditions, photosystem 2 (PS2) photochemical efficiency, determined by the ratio of variable to maximum fluorescence (Fν/Fm), increased during the ...

Epigenetic Aging in Brain Tissue of the Self‐Fertilizing Vertebrate, Kryptolebias marmoratus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Using the self‐fertilizing vertebrate Kryptolebias marmoratus, we developed an epigenetic clock from brain tissue that predicts chronological age with high accuracy, demonstrating that DNA methylation changes consistently with age even in the near absence of genetic variation. The 40 age‐associated CpG sites identified map to genes with conserved roles

Macroalgae associated with aerial roots of Rhizophora manglein Islas del Rosario, Colombia, Southwestern Caribbean

open access: yesCaldasia, 2020
The roots of the red mangrove, Rhizophora mangle, provide a nursery habitat for many species, due to the tridimensional structure they provide, which delimits an area difficult to access to large predators.

Hydrological seasonality shapes microbial biomass and diversity in an equatorial estuarine mangrove

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Mangroves are pantropical marine forests rooted in soft sediments and subject to pronounced seasonal variability. However, the effects of these hydrological fluctuations on root‐associated prokaryotic communities remain poorly understood, particularly in underexplored regions like the Guianas.
