Potential Invasive Indo‐Pacific Acropora in a Coral Reef of Venezuela: A Contribution to Their Morphological and Molecular Knowledge

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.

Spatial distribution of bivalvia (Mollusca) in the soft-bottoms of Ilha Grande Bay, Rio de Janeiro, Brazil

open access: yesBrazilian Journal of Oceanography, 1998
The spatial distribution of bivalve molluscs and its relation to granulometry and to the percentage of organic matter and silt-clay were studied in the Saco do Céu Inlet. Bivalves and samples of sediment were collected in 39 stations, in January and July
