Promoting Biofilm Formation by Serratia marcescens on Three Types of Artificially Aged Microplastics Under Marine Conditions

Microplastics
Bacterial biofilms on different types of microplastics in aquatic environments have become an increasing ecological and public health concern. In this context, this study investigated biofilm formation on virgin and aged microplastics under marine ...

Behavioral profile predicts ethanol preference in adolescent mice, but not in adults: A machine learning approach. [PDF]

Alcohol Clin Exp Res (Hoboken)
The present study reveals that adolescent behavioral phenotypes strongly predict ethanol preference in mice, while no predictive patterns emerged in adulthood. Machine learning analysis identified sucrose preference as a positive predictor and sociability as a negative predictor of alcohol intake, highlighting natural reward sensitivity and social ...

FLUTUAÇÕES CLIMÁTICAS EM CABO FRIO

Geography Department, University of Sao Paulo, 1997
Na atualidade, fala-se muito em “mudanca climatica” em torno da Lagoa de Araruama, no Estado do Rio de Janeiro. Procuramos testar tal afirmativa na localidade de Cabo Frio, ao longo de sessenta anos de observacoes meteorologicas continuas (1921-1980), na procura de identificar qualquer “mudanca climatica” por menor que fosse, de algum significado, que ...

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).
