Consumer resilience suppresses the recovery of overgrazed ecosystems. [PDF]

Ecol Appl
Abstract Many heterotroph species perish when faced with severe food limitation; others can persist, adapt, and thrive. Sea urchins are emblematic of this paradox: they can overgraze kelp forests to form barren habitats, but can then survive for decades in these nutritionally depauperate seascapes.

Association Analysis of Seagrass Coverage and Human Activities in Nusa Lembongan

Jurnal Biodjati, 2022
Nusa Lembongan has high marine biodiversity, including seagrass. Seagrass is a plant that lives submerged in a marine or estuary water that functions as a nursery ground, trapping sediment, and beach protector, so it is important to know the condition of

Contrasting Rare Earth Element Signatures Between Stromatolitic Carbonates and Lagoon Waters at Shark Bay, Western Australia: Implications for Paleo-Environmental Reconstructions of Microbial Habitats. [PDF]

Geobiology
ABSTRACT Rare earth elements and yttrium (REY) signatures in stromatolitic carbonates have emerged as powerful geochemical proxies for reconstructing paleo‐depositional environments of microbial habitats. The applicability of such a proxy relies on the assumption that REY substitutes for calcium into crystal lattices, directly reflecting the ...

Seasonal behavior of Thalassia testudinum (Hydrocharitaceae) metabolites

Revista de Biología Tropical, 2016
The marine angiosperm Thalassia testudinum, commonly known as turtle grass, is a dominant seagrass that grows in the Caribbean Sea shelf associated to Syringodium filiforme. The hydroalcoholic extract of T. testudinum is rich in polyphenols; the most abundant metabolite in this extract is thalassiolin B, a glycosilated flavonoid with skin damage ...

Carbon Stored on Seagrass Beds in Gili Maringkik, Lombok, Indonesia

Biotropia: The Southeast Asian Journal of Tropical Biology, 2023
Seagrass beds are an important vegetation for reducing the impact of global warming besides the function of forest and mangroves vegetation. The research aims to find the composition of seagrass species, density, seagrass coverage, seagrass standing ...

Classification of Marine Seagrasses by Leaf Fractal Dimensions Analysis

Recoletos Multidisciplinary Research Journal, 2013
This particular study used the fractal dimensions of leaves of sea-grasses that were found near the Marine Protected Area (MPA) of Punta, Panaon, Misamis Occidental to determine if the same can be used for classification purposes.

Spatial Patterns and Overlap of Sedimentary and Rhizosphere Microbiomes of the Seagrass Zostera capensis. [PDF]

Environ Microbiol Rep
Sedimentary microbiomes and, for the first time, rhizosphere microbiomes of Zostera capensis, South Africa's most abundant seagrass, were characterised using 16S rRNA metabarcoding across three estuaries. After accounting for seawater‐derived microbes, we found that sediment and rhizosphere communities largely overlapped but also harbor distinct core ...

Population Genetic Structure and Biogeographic Distribution of Tropical <i>Halodule uninervis</i> in the Bohol Sea and Adjacent Waters in the Philippines. [PDF]

Ecol Evol
Genome‐wide SNP markers reveal patterns of genetic structure and connectivity among Halodule uninervis populations across the Bohol Sea. Migration rates (≥ 0.025 and ≤ 0.040) indicate asymmetric gene flow and heterogeneous connectivity, suggesting a semi‐connected metapopulation shaped by clonal reproduction and regional oceanographic circulation ...
