A new Hyphessobrycon (Characiformes: Acestrorhamphidae) of the Hyphessobrycon agulha lineage of Hyphessobryconinae from the lower Aripuanã basin, Brazil, with comments about the lineage

Journal of Fish Biology, EarlyView.
Abstract A new species of Hyphessobrycon is described from a tributary of Rio Jatuarana, lower Rio Aripuanã basin, Rio Madeira basin, Apuí, Amazonas. The new species is part of the Hyphessobrycon agulha lineage, with the typical midlateral narrow black stripe immediately followed dorsally by an iridescent stripe.

Range extension and first records of Coryphaenoides striaturus Barnard, 1925 and Coryphaenoides subserrulatus Makushok, 1976 (Macrouridae: Gadiformes) in Brazilian waters, Southwest Atlantic, using integrative taxonomy

Journal of Fish Biology, EarlyView.
Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

The Agulhas Current [PDF]

Eos, Transactions American Geophysical Union, 2008
Many people in the United States know about the Gulf Stream, the impressive boundary current along the eastern U.S. coast that carries large amounts of heat poleward and, after separation from the coast, across the North Atlantic. Its impact on warming the eastern United States and the North Atlantic region including western Europe is also well known ...

Frontal‐Driven Water‐Mass Transformation in a Western Boundary Current: Evidence From the Yucatan Current

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract We report the recurrent formation of waters with thermohaline properties similar to Gulf Common Water (GCW) in the western Yucatan Channel, absent upstream in the Caribbean. Mooring observations and a partial submesoscale‐resolving model show that these Yucatan GCW forms locally when the Yucatan Current separates from the slope, intensifying a

Primary Productivity and Habitat Depth Shape Developmental Mode in European Marine Gastropods

Ecology and Evolution, Volume 16, Issue 3, March 2026.
Thorson's rule suggests that marine gastropods in colder, high‐latitude regions tend to have non‐pelagic (non‐drifting) larval development. However, this study on 94 European gastropod species found that the rule disappears when examined at finer spatial scales, with temperature and phylogeny having little influence.

Avaliações ultra-sonográfica, macroscópica e histológica da biopsia testicular em ovinos

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2002
Devido ao fato da biopsia testicular poder acarretar hemorragia, inflamação, degeneração, aderência e fibrose, especialmente com as técnicas incisionais ou abertas, este trabalho avaliou a aplicabilidade de uma técnica menos invasiva (biopsia com agulha ...

Changes in Shell and Crystal Structure From Life to Sediments: An EBSD Characterization of Subantarctic Planktic Foraminifera

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Fossil foraminifera store a wealth of information about past climates and ecosystems in their shell chemistry. However, these element and isotope signals may be affected by post‐mortem diagenesis (i.e., alteration). Here, we use Electron Backscatter Diffraction (EBSD; crystal orientation mapping) to evaluate the structural integrity of sub ...
