"Somos a terra lutando para sobreviver": histórias de vida de mulheres agroecologistas

Psicol. ciênc. prof; 43 (), 2023
A luta pela terra e seu uso incide na forma como as subjetividades têm sido produzidas no Brasil. No contexto capitalista, patriarcal e machista, vive-se um processo de exploração da mão de obra de mulheres e de recursos naturais da Terra. Este estudo objetivou conhecer histórias de vida de mulheres...

Seasonal droughts during the Miocene drove the evolution of Capparaceae towards Neotropical seasonally dry forests

Rev. biol. trop; 70 (1), 2022
Abstract Introduction: Neotropical seasonally dry forest (NSDF) climatic constraints increased endemism, and phylogenetic niche conservatism in species that are restricted to this biome. NSDF have a large number of endemic Capparaceae taxa, but it is unknown if phylogenetic niche conservatism has played ...

Basic ecology of ant gardens in a dry-premontane transitional forest

Rev. biol. trop; 70 (1), 2022
Abstract Introduction: "Ant gardens'' are ant nests located at different heights on trees on which vascular epiphytic plants that have been transported and sown by ants have germinated. Although this mutualistic relationship has been studied in humid tropical ecosystems, information on other tropical and...

Impact of plot size on tropical forest structure and diversity estimation

Rev. biol. trop; 70 (1), 2022
Abstract Introduction: Inventories are essential for forest management, but, in the Amazon region, the absence of standardization produces information loss, low accuracy, and inconsistent measurements. This prevents valid comparisons and compromises the use of information in networks and software. Sampli...

Diversity, abundance and ecological importance of plant species for medical use in tropical forest of Tingo Maria, Peru

Peru is a megadiverse country due to the large number of animal and plant species. Its diversity derives from the different ecoregions present that developed with geological evolution. Much of its plant diversity is contained in the Peruvian Amazon, which includes a large proportion of plant species, man...

Seasonality and forest edge as drivers of Tradescantia zebrina Hort. ex Bosse invasion in the Atlantic Forest

Braz. j. biol; 82 (), 2022
As a result of biodiversity and ecosystem service losses associated with biological invasions, there has been growing interest in basic and applied research on invasive species aiming to improve management strategies. Tradescantia zebrine is a herbaceous species increasingly reported as invasive in the u...

Helminth fauna of Norops fuscoauratus (D'Orbigny, 1837) (Squamata: Dactyloidae) in the Atlantic Forest, northeastern Brazil

Braz. j. biol; 82 (), 2022
The composition of macro endoparasites associated with the lizard Norops fuscoauratus (Squamata) was analysed in two localities in the Atlantic Forest on the northeast of Brazil between December 2012 and July 2015. 74 specimens of N. fuscoauratus were examined and five species of helminths were reported,...

Diversidad de vectores de Plasmodium y rasgos funcionales de los árboles del bosque perturbado en Tingo María, 2022

Las comunidades vegetales en la zona de Tingo María, Perú, se encuentran sometidas a los efectos del cambio climático, generando modificaciones en su biodiversidad, impactando su ecosistema. Por otra parte, se ha referido que actividades que ocasionan perturbación de bosques tropicales pueden favorec...

Selectivity of herbicides applied to Brazilian tree species at post-emergence

The presence of weeds in silvicultural systems has been considered one of the main obstacles to the success of projects designed to recover degraded areas. The aim of this study was to evaluate the selectivity of herbicides applied at post-emergence in the initial growth of seedlings of capixingui (Croto...
