Do arthropods and diseases affect the production of fruits on Caryocar brasiliense Camb. (Malpighiales: Caryocaraceae)?

Braz. j. biol; 84 (), 2024
Frequencies, magnitudes, and distributions of occurrence can affect the events. The problem can be worse or the solution better if greater frequencies and magnitudes are presented with aggregated distribution in the production system. Indices, hence, are used to assist in decision-making on certain issue...

Woody species distribution across a savanna-dry forest soil gradient in the Brazilian Cerrado

Braz. j. biol; 83 (), 2023
Abstract Although richness and distribution of woody species in the Cerrado physiognomies have been extensively studied, the shifts of woody species from savanna physiognomies to dry forests have not yet been addressed. Here, we investigate the effect of soil physical-chemical traits on the woody species...

Impact of sowing dates on the yield efficiency of upland rice cultivars

Biosci. j. (Online); 38 (), 2022
The choice of cultivars adapted to different regions and the determination of the best sowing dates are indispensable tools for crop development. This allows the installation of the crop in times favorable to its development, as well as cultivars that manage to reach their maximum yield potential. The ob...

Bacterial diversity in high Andean grassland soils disturbed with Lepidium meyenii crops evaluated by metagenomics

Braz. j. biol; 82 (), 2022
Soil quality is usually determined by its physical-chemical characteristics without taking into account the bacterial communities that play a fundamental role in the chemical decomposition of plant nutrients. In this context, the objective of the study was to evaluate bacterial diversity in high Andean g...

Effects of nitrogen and phosphorus availability on the early growth of two congeneric pairs of savanna and forest species

Braz. j. biol; 82 (), 2022
In the tropical region, savannas and seasonal forests, both highly diverse biomes, occur side by side, under the same climate. If so, that mosaic cannot be explained solely by climatic variables, but also by fire, water availability and soil status. Nutrient availability in the soil, especially nitrogen ...

Characterization of edaphic fauna in different monocultures in Savanna of Piauí

Braz. j. biol; 81 (3), 2021
Abstract Vegetation cover may show diversity and composition patterns of the soil invertebrate community, as a function of litter quantity and quality in a specific habitat. The objective of this work was to characterize the distribution of edaphic fauna in different monocultures. The study was carried o...

Genetic diversity and structure in natural populations of Cajui from Brazilian Cerrado

Biosci. j. (Online); 37 (), 2021
Cajui (Anacardium spp.) is a native fruit tree (small cashew) of the Brazilian Cerrado and possesses the potential for commercialization. However, cajui exploitation occurs exclusively through extractivism in the absence of conservation strategies. The lack of conservation strategies may lead to a decrea...

Composição nutricional de frutos do Cerrado mato grossense: cajuzinho do cerrado (Anacardium humile A. St.-Hil. ), curriola (Pouteria ramiflora (Mart. ) Radlk.) e inharé (Brosimum gaudichaudii Trécul)

Este trabalho teve como objetivo a caracterização nutricional (umidade, proteínas, lipídeos, cinzas e açúcares totais), quantificação do Valor Energético Total (VET) e determinação do teor de carotenoides totais dos frutos de cajuzinho do cerrado (Anacardium humile A.St.-Hil.), curriola (Pout...

Craniometric geographical variation in Hylaeamys megacephalus populations

Pesqui. vet. bras; 40 (9), 2020
Hylaeamys megacephalus (G. Fisher, 1814) presents great genetic diversity and wide geographical distribution, and occurs in both the Amazon and Cerrado biomes. Because of its generalist aspect, this species tolerates different eating habits and habitats. It occurs in flooded and dry areas and is predomin...

Brazilian cerrado species: wood characteristics

Biosci. j. (Online); 36 (4), 2020
The characterization of wood anatomy and proprieties can provide subsidies for rational use of tree species. Enables, oftentimes, the definition of technological potential of wood - and wood products - through the assessment of quality information and also allows it ́s correct identification, contribu...
