Unravelling the drivers of island species richness in tropical savannas

Journal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.

Obtenção de concretos auto-escoantes zero-cimento a partir do controle reológico da matriz

Cerâmica, 2000
Os concretos refratários auto-escoantes com reduzido teor de cimento têm se destacado pelo fato de associarem a facilidade de aplicação dos concretos de elevada fluidez, com o bom desempenho termomecânico dos refratários contendo baixo teor de CaO ...

Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change

Global Change Biology, Volume 32, Issue 4, April 2026.
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Multiscale Environmental Drivers of Aquatic Insect Assemblages in Cerrado Streams

Austral Ecology, Volume 51, Issue 3, March 2026.
Multi‐scale drivers of aquatic insect communities in Cerrado streams. The gradient (from left to right) indicates increasing spatial scale, showing that abundance is influenced by local factors (conductivity, temperature), taxonomic richness responds to agricultural land use at an intermediate scale, and community composition is structured by regional ...

Efeitos da agitação mecânica e matéria orgânica na análise granulométrica do solo Effects of mechanical agitation and soil organic matter on soil particle size analysis

Revista Brasileira de Engenharia Agrícola e Ambiental, 2011
A parte mineral do solo é classificada conforme a granulometria das partículas em argila, silte e areia (fina e grossa) e sua matéria orgânica pode influir no tamanho e na estabilidade dos agregados.

Animal–Plant Interactions Under Defaunation: Consequences for Amazonian Trees of Commercial Interest

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally investigated the effects of medium‐ and large‐sized mammal defaunation on the removal and fate of seeds from economically important forest species in Amazonian forests. Our results show that mammal exclusion significantly reduced seed removal, although the magnitude of this effect varied among plant species.

Ciclo de vida, estruturas reprodutivas e dispersão de populações experimentais de capim-carrapicho (Cenchrus echinatus L.) Life cycle, reproductive structures and dispersion of experimental populations of sandbur (Cenchrus ech inatus L.)

Planta Daninha, 1984
A partir de semeaduras mensais de 500 cariopses em áreas de 5,00 x 3,80 m em sulcos distanciados de um metro e com profundidade de 3 cm foram obtidas 12 populações experimentais.

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

A New Method of Fruit Marking for Studies on Chiropterochory

Biotropica, Volume 58, Issue 1, January 2026.
We used edible glitter to mark 15,526 fruits of three chiropterochorous plants at 700, 1000, 2000, and 3200 m from a bat roost in Brazil's caatinga. Glitter from all distances was detected at the roost, allowing the identification of specific feeding areas accessed, providing a new approach for zoochory studies.
