Variação temporal de características morfológicas de folhas em dez espécies do Parque Nacional da Restinga de Jurubatiba, Macaé, RJ, Brasil Temporal variation of morphological leaf traits in ten species from Restinga of Jurubatiba National Park, Macaé, Rio de Janeiro State, Brazil

Acta Botânica Brasílica, 2007
Ordenar espécies em relação a um contínuo de variação de características foliares pode ser útil para inferir sobre a suscetibilidade de uma comunidade a alterações na disponibilidade de recursos e/ou condições ambientais ao longo do tempo.

Toward a Biocultural Synthesis of the Peopling of the Americas: Introduction to the Special Issue Hacia una síntesis biocultural del poblamiento de las Américas: introducción al número especial Rumo a uma síntese biocultural do povoamento das Américas: introdução ao número especial

American Journal of Biological Anthropology, Volume 188, Issue 3, November 2025.
ABSTRACT This article introduces the special issue Toward a Biocultural Synthesis of the Peopling of the Americas, which brings together contributions that explore the origins and diversity of Indigenous populations across North, Central, and South America and the Caribbean. The volume grew out of an invited symposium held at the 90th Annual Meeting of

Biomass production of tropical trees across space and time: The shifting roles of diameter growth and wood density

Journal of Ecology, Volume 113, Issue 11, Page 3141-3158, November 2025.
Diameter growth is an important and good indicator of forest carbon production. However, size‐related changes in wood density, which are usually neglected, are critical for accurate short‐ and long‐term carbon assessments, especially in tropical humid sites.

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

Biotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.

Seasonal and intracanopy shifts in the fates of absorbed photons in central Amazonian forests: implications for leaf fluorescence and photosynthesis

New Phytologist, Volume 248, Issue 1, Page 76-91, October 2025.
Summary Recent studies have shown a linear relationship between solar‐induced Chl fluorescence (SIF) and gross primary productivity (GPP) at large scales. However, this relationship diverges at finer leaf scales, particularly in tropical forests with complex canopy structures.

Eventos extremos de precipitação no sertão paraibano: Variação espaço-temporal

Revista Verde de Agroecologia e Desenvolvimento Sustentável, 2017
A variabilidade pluviométrica é característica marcante na região semiárida, não somente nos totais anuais, como também na quantidade e distribuição espacial. Com o objetivo de contribuir para o entendimento dos eventos extremos de precipitação na região

Racing Amidst Change: Urbanization and Climate Alter Functional Traits and Distribution of an Amazonian Parthenogenetic Lizard

Biotropica, Volume 57, Issue 5, September 2025.
By comparing native and neonative populations of an Amazonian lizard, we examine how urban environments and climate change impact its functional traits, while also predicting its future distribution. Our findings offer insights into how some species may adapt to human‐altered landscapes, showing that not all are negatively affected by these changes ...

Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

Tailoring temporal description logics for reasoning over temporal conceptual models [PDF]

, 2011
Temporal data models have been used to describe how data can evolve in the context of temporal databases. Both the Extended Entity-Relationship (EER) model and the Unified Modelling Language (UML) have been temporally extended to design temporal ...

Efeito da lua e da maré na captura de peixes em uma planí­­cie de maré da Baí­­a de Paranaguá, Paraná, Brasil

Boletim do Instituto de Pesca, 2018
Em uma planí­­cie de maré da Baí­­a de Paranaguá foi analisada a influência da maré e da fase lunar sobre as capturas de peixes. As coletas foram realizadas na preamar e baixa-mar das marés de sizí­­gia (lua cheia) e de quadratura (lua minguante), entre
