Biomass and vegetation index by remote sensing in different caatinga forest areas

Ciênc. rural (Online); 52 (2), 2022
Continued unsustainable exploitation of natural resources promotes environmental degradation and threatens the preservation of dry forests around the world. This situation exposes the fragility and the necessity to study landscape transformations. In addition, it is necessary to consider the biomass quan...

Gastrointestinal parasites of Leontopithecus chrysomelas in the Atlantic Forest, Brazil

Abstract We performed coproparasitological testing of free-living golden-headed lion tamarins, Leontopithecus chrysomelas, using the Hoffmann-Pons-Janner method. In total, we collected 118 samples from ten groups: four living in Federal Protected Area and six living in Non-Protected Areas of cocoa farms....

Water quality in the Lachuá Ecoregion Landscape: Comparing streams from Forest, Milpa, and an Oil Palm plantation

Cienc. tecnol. salud; 9 (1), 2022
The hydrological network in the Lachuá Ecoregion (EL), Alta Verapaz, Guatemala, hosts high levels of biodiversity and supplies water to 44 Mayan communities. Despite this critical fact, this network has been threatened by scarcely monitored industrial activities including the rapidly expanding oil palm ...

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 ...

Anadenanthera colubrina (Fabaceae) logs in the Atlantic Forest biome: first host plant for Thoracibidion lineatocolle (Col: Cerambycidae) and a new host for Temnopis megacephala (Col: Cerambycidae)

Braz. j. biol; 82 (), 2022
Wood-boring beetles develop in live trees and dead wood, performing ecological services such as decomposition and regulation of forest resources. Species of the Cerambycidae family, widely distributed in the world, bore into the trunks of trees and dead wood in native and cultivated areas. The objective ...

Regional concentration of native fuelwood production in Rio Grande do Norte, Brazil (1990–2017)

Ciênc. rural (Online); 52 (10), 2022
This paper examined the regional concentration of native fuelwood production in Rio Grande do Norte, Brazil, between 1990-2017. Information on native fuelwood was gathered from forestry activities collected by the Brazilian Institute of Geography and Statistics (IBGE). This study analyzed the current sit...

Filamentous fungi occurrence on Molossus molossus (Pallas, 1766) (Chiroptera: Molossidae) present in an Atlantic Forest remnant in Southern Brazil

Braz. j. biol; 81 (4), 2021
Abstract The bats usually inhabit shelters with favorable conditions for fungal proliferation, including pathogenic and opportunistic species. The fungal diversity present on bats is little known and the studies are scarce in Brazil, which only a work has been performed in Cerrado and Pantanal biomes. Th...
