Northward Shifts in the Polar Front Preceded Bølling and Holocene Warming in Southwestern Scandinavia

open access: yesGeophysical Research Letters, 2020
The last deglaciation in northern Europe provides an opportunity to study the hydrologic component of abrupt climate shifts in a region with complex interactions between ice sheets and oceanic and atmospheric circulation.

Digenean trematodes infecting the frigate tuna Auxis thazard (Scombriformes, Scombridae) off the Rio de Janeiro coast, Brazil, including molecular data

open access: yesParasite, 2022
Although some parasitological efforts have focused on the frigate tuna Auxis thazard (Lacepède) (Scombriformes, Scombridae) in Brazil, its digenean fauna remains poorly known.

Invasive species in the Northeastern and Southwestern Atlantic Ocean: A review [PDF]

open access: yesMarine Pollution Bulletin, 2017
The spread of non-native species has been a subject of increasing concern since the 1980s when human-mediated transportation, mainly related to ships' ballast water, was recognized as a major vector for species transportation and spread, although records of non-native species go back as far as 16th Century. Ever increasing world trade and the resulting

Multiple introductions and secondary dispersion of Tubastraea spp. in the Southwestern Atlantic. [PDF]

open access: yesSci Rep, 2019
AbstractAccidental introduction through ballast water and biofouling are currently the main factors responsible for spreading non-indigenous species in the marine realm. In the Southwestern Atlantic, two scleractinian corals,Tubastraea coccineaandT. tagusensis, have been introduced by opportunistic colonization in 1980 and are now widespread along more

The influence of the Brazil and Malvinas Currents on the Southwestern Atlantic Shelf circulation [PDF]

open access: yesOcean Science, 2010
Abstract. The oceanic circulation over the southwestern Atlantic shelf is influenced by large tidal amplitudes, substantial freshwater discharges, high wind speeds and – most importantly – by its proximity to two of the largest western boundary currents of the world ocean: the Brazil and Malvinas currents.

Differences in sagittal otoliths between two morid species: insights into the genus Physiculus (Moridae: Gadiformes)

open access: yesNeotropical Ichthyology
Sagittae are widely used as tools in taxonomic and ecological studies of fishes, especially when external morphological characters are conserved or ambiguous. We analyzed morphological variation between two congeneric species of Physiculus: P.

Templex for Lagrangian dynamics in the Southwestern Atlantic

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science
This work presents the first application of the templex approach to observational datasets, using Lagrangian trajectories obtained from satellite altimetry in the ocean. The templex is a recent topological construct that extends classical ideas from template theory to higher-dimensional systems.
