Influence of the Great Amazon Reef System and Pleistocene sea-level drops on the phylogeography of Haemulon aurolineatum (Haemulidae) [PDF]

PeerJ
Background Phylogeography is based on the principle that species exhibit genetic structure shaped by biogeographic, ecological or environmental barriers, using both genetic and geographic components, offering valuable insights into evolutionary processes.

Freshwater oyster Bartlettia stefanensis (Moricand 1856) reefs revealed by Amazon drought [PDF]

Acta Amazonica
Calcrete platforms covered by tightly packed individuals of the Etheriidae freshwater oyster Bartlettia stefanensis (Moricand 1856) forming small reefs were exposed in several spots of the Muru river, Acre, Brazil, during the 2024 drought.

Integrative Taxonomy of Amazon Reefs' Arenosclera spp.: A New Clade in the Haplosclerida (Demospongiae)

Frontiers in Marine Science, 2017
Two new Arenosclera are described here on the basis of materials obtained from Amazon reefs in 2014, A. amazonensis sp. nov. and A. klausi sp. nov. Both are clearly distinct from all other Arenosclera by their erect, solid funnel to lamellate habit ...

Genetic diversity patterns of lionfish in the Southwestern Atlantic Ocean reveal a rapidly expanding stepping-stone bioinvasion process [PDF]

Scientific Reports, 2023
In 2020, multiple lionfish (Pterois spp.) records along the equatorial Southwestern (SW) Atlantic revealed a new expansion of these potentially damaging invasive populations, which could impact over 3500 km of Brazilian coastline over the next few years,

Zooplankton From a Reef System Under the Influence of the Amazon River Plume [PDF]

Frontiers in Microbiology, 2018
At the mouth of the Amazon River, a widespread carbonate ecosystem exists below the river plume, generating a hard-bottom reef (∼9500 km2) that includes mainly large sponges but also rhodolith beds.

Depth drive shifts in the fish and benthic assemblages of the South American Reef System [PDF]

Scientific Reports
The low-latitude habitats of the South American reef system have a high endemism and represent important stepping-stones due to the connectivity with Amazon and Caribbean reefs.

ROPE TO THE SEA: OBSERVATION OF THE FISHING ROPE ACTING AS ARTIFICIAL SUBSTRATA TO FIXATION OF CORAL Astrangia solitaria (Le SUEUR, 1817) COLLECTED IN THE GREAT AMAZON REEF SYSTEM (GARS)

Environmental Smoke
Herein, we report the first observation of the coral Astrangia solitaria (Le Sueur, 1817) adhered on the polypropylene fishing rope (artificial substrate), collected in the areas of the Great Amazon Reef System (GARS). The specimens of A.

Geomorphometric Seabed Classification and Potential Megahabitat Distribution in the Amazon Continental Margin

Frontiers in Marine Science, 2020
The geomorphometry of the northeast portion of the Amazon Shelf, along the Brazilian Equatorial Margin (BEM), off the Amazonas River mouth, was analyzed using the Benthic Terrain Modeler, a spatial analysis technique that defines physical megahabitat ...
