Distribution and taxonomic identity of the species of Narcine (Toperdiniformes: Narcinidae) in the southwestern Atlantic Ocean. [PDF]

open access: yesJ Fish Biol
Abstract The genus Narcine is the most diverse among electric rays of the order Torpediniformes and is also the only electric ray genus with more than one species occurring in South American waters: Narcine brasiliensis and Narcine bancroftii. The first species has been historically described as distributed from Brazil's southeast coast down to ...

Mitonuclear and phenotypic discordance in an Atlantic Forest frog hybrid zone. [PDF]

open access: yesEcol Evol
We characterized the patterns of genetic and phenotypic variation in a contact zone between Cycloramphus dubius and Cycloramphus boraceiensis, two sister species of frogs endemic to the Atlantic Coastal Forest of Brazil. We detected discordance in patterns of introgression across the three data types.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Brazil climate highlights 2023. [PDF]

open access: yesAnn N Y Acad Sci
Abstract In the year 2023, the Earth experienced the highest near‐surface temperature anomalies ever recorded until then. In addition, several extreme weather and climate events occurred around the world, including in Brazil. In this context, the primary objective of this study is to analyze the anomalous temperature and precipitation patterns observed

Reassessment of generic boundaries in Neotropical Chrysophylloideae (Sapotaceae): Eleven reinstated genera and narrowed circumscriptions of Chrysophyllum and Pouteria

open access: yesTAXON, Volume 72, Issue 2, Page 307-359, April 2023., 2023
Abstract Classifications of the pantropical plant family Sapotaceae based solely on morphology have historically recognized between 125 and 53 genera. Phylogenetic analyses using molecular data have repeatedly demonstrated that broad concepts of two large genera belonging to subfamily Chrysophylloideae, Chrysophyllum and Pouteria, are untenable and ...

Revealing the drivers of taxonomic and functional diversity of nearshore fish assemblages: Implications for conservation priorities

open access: yesDiversity and Distributions, Volume 28, Issue 8, Page 1597-1609, August 2022., 2022
Abstract Aim Understanding patterns and drivers of biodiversity are essential towards developing effective conservation strategies for shallow marine habitats broadly. However, little is known about the natural and anthropogenic factors that structure fish biodiversity of sandy beaches, one of the largest and most socio‐economically valuable nearshore ...

Phylogeography of Agathistoma (Turbinidae, Tegulinae) snails in tropical and southwestern Atlantic

open access: yesZoologica Scripta, Volume 51, Issue 1, Page 76-90, January 2022., 2022
Abstract The rocky intertidal gastropods Agathistoma viridulum and A. hotessierianum occur from the Caribbean to southern Brazil, with a gap in the equatorial region, giving them an anti‐tropical distribution. We used sequences from mitochondrial genes to elucidate the phylogeography of A. viridulum and A.

Thin layers in the coastal zone of Ubatuba, Brazil: Mechanisms of formation and dissipation

open access: yesLimnology and Oceanography, Volume 66, Issue 2, Page 558-574, February 2021., 2021
Abstract Thin layers are vertically compressed, horizontally extensive, highly concentrated features comprised of plankton and/or particles. They are critical components of the marine ecosystem, likely playing a key role in the life histories and evolutionary trajectories of species found in, or, interacting with them.

Marine debris ingestion by sea turtles (Testudines) on the Brazilian coast: an underestimated threat? [PDF]

open access: yes, 2015
Assessment of marine debris ingestion by sea turtles is important, especially to ensure their survival. From January to December 2011, 23 specimens of five species of sea turtleswere found dead or dying after being rehabilitated ...
