Mammal defaunation leads to biotic homogenization of plant communities in tropical rainforests. [PDF]

Ecology
Abstract Biotic homogenization is the process in which species communities become increasingly similar across different regions over time. This phenomenon has substantial ecological, evolutionary, and economic implications, primarily driven by human activities such as habitat destruction, invasive species introduction, and climate change.

Characterization of films and film‐forming solutions of chitosan/thermoplastic rice starch associations: Role of starch oxidation and plasticizer type in the molecular interactions

Polymer Engineering &Science, Volume 63, Issue 12, Page 4127-4139, December 2023., 2023
The OH polyol groups mainly controls film‐forming and film properties. Abstract Polysaccharide films are alternative sources to replace fossil‐based compounds. This study aimed to use rice starch modified by gelatinization and oxidation processes. Different properties were observed after blending it with chitosan and polyols, as evaluated on the film ...

Tropical and temperate differences in the trophic structure and aquatic prey use of riparian predators

Ecology Letters, Volume 26, Issue 12, Page 2122-2134, December 2023., 2023
The influence of aquatic resource‐inputs on terrestrial communities is poorly understood, particularly in the tropics. Using stable isotopes to trace aquatic prey use and quantify the impact on trophic structure in 240 riparian arthropod communities in tropical and temperate forests, we found riparian predators consumed more aquatic prey and were more ...

Narrowly defined taxa on a global scale: The phylogeny and taxonomy of the genera Catriona and Tenellia (Nudibranchia, Trinchesiidae) favours fine‐scale taxonomic differentiation and dissolution of the “lumpers & splitters” dilemma

Evolutionary Applications, Volume 16, Issue 2, Page 428-460, February 2023., 2023
Abstract By applying morphological and molecular data on two genera of the nudibranch molluscs it is shown that the tension between taxonomic practice and evolutionary processes persists. A review of the related genera Catriona and Tenellia is used to demonstrate that the fine‐scale taxonomic differentiation is an important tool in the integration of ...

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

J 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 ...

Interação das tartarugas marinhas com a pesca artesanal de cerco-fixo em Cananéia, litoral sul de São Paulo

Biotemas, 2010
As tartarugas marinhas são répteis que ocorrem ao longo de toda a costa brasileira, migrando entre as áreas de alimentação e de reprodução. O consumo de sua carne e ovos é um hábito histórico de diversas comunidades litorâneas por todo mundo. Entretanto,

Intense coastal sedimentation and erosion in the Cananéia outlet, southern state of São Paulo, Brazil

Brazilian Journal of Oceanography, 1983
The extreme mobility of submerged sand bars at the mouth of the Cananeia outlet has made safe access difficult to the lagoonal region of Cananeia, on the southern coast of the State of São Paulo.

Differential Acetyl Cholinesterase Inhibition by Volatile Oils from two Specimens of (Myrtaceae) Collected from Different Areas of the Atlantic Rain Forest

Natural Product Communications, 2009
The volatile oil composition and anti-acetyl cholinesterase activity were analyzed in two specimens of Marlierea racemosa growing in different areas of the Atlantic Rain Forest (Cananéia and Caraguatatuba, SP, Brazil).

Nuclear abnormalities in erythrocytes and morphometric indexes in the catfish Cathorops spixii (Ariidae) from different sites on the southeastern Brazilian coast

Brazilian Journal of Oceanography, 2012
Nuclear abnormalities in erythrocytes (NAE) were taken as biomarkers in the catfish Cathorops spixii (Ariidae) sampled in an estuary little affected by human activity (Cananéia) and in three regions (Santos Channel: SC, Santos Bay: SB and São Vicente ...

Satellite and Reanalysis Dataset Dependence of ETCCDI Extreme Precipitation Trends in Paraná, Southern Brazil

International Journal of Climatology, EarlyView.
Extreme precipitation trends detected in Paraná, Southern Brazil (1983–2024), are strongly conditioned by the dataset used, with reanalyses indicating coherent inland drying and longer dry spells, observations retaining stronger mesoscale heterogeneity, and satellite products often showing declines in short‐duration extremes. Monthly diagnostics reveal
