Resource suitability drives low use of avian‐excavated tree cavities: A multi‐state occupancy dynamics approach

Journal of Animal Ecology, Volume 94, Issue 11, Page 2295-2307, November 2025.
Birds that nest in tree cavities are sometimes dependent on a few cavity‐excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because excavated cavities may be unsuitable for continued use, even when available for several years after excavation.

Uncoupling human and climate drivers of late Holocene vegetation change in southern Brazil [PDF]

, 2018
In the highlands of southern Brazil an anthropogenitcally driven expansion of forest occurred at the expense of grasslands between 1410 and 900cal BP, coincident with a period of demographic and cultural change in the region.

Density of Araucaria angustifolia wood from overstocked stand

Pesquisa Florestal Brasileira, 2016
The aim of this work was to evaluate the radial and longitudinal variations of wood specific gravity in an overstocked stand of Araucaria angustifolia, with 65 years. The stand was located in the National Forest of Açungui, Campo Largo, Parana State, Brazil, with thinning recorded between 1970 and 1980, without subsequent thinnings.

Unveiling Dispersal Strength on a Metacommunity of Dung Beetles in a Heterogeneous Landscape

Austral Ecology, Volume 50, Issue 11, November 2025.
Our study examines the dispersal dynamics of dung beetles across heterogeneous landscapes, shedding light on their habitat preferences and community structure. We identified patterns of dispersal and habitat association across forest, woodland and grassland habitats.

BIOMASSA E CARBONO ORGÂNICO EM POVOAMENTOS DE Araucaria angustifolia (Bertol.) Kuntze

Ciência Florestal, 2015
The objective was to estimate the biomass and organic carbon in Araucaria angustifolia stands with different ages. The Araucaria angustifolia stands studied were not pruning but were thinning in difference ages.

Aerial sketchmapping for monitoring forest conditions in Southern Brazil. [PDF]

, 2015
Aerial sketchmapping is a simple, low cost remote sensing method used for detection and mapping of forest damage caused by biotic agents (insects, pathogens and other pests) and abiotic agents (wind, fire, storms, hurricane, ice storms) in North America.

Distribution of Functional Traits Along Climatic Gradients in the Subtropical Atlantic Forest

Austral Ecology, Volume 50, Issue 11, November 2025.
We assessed the correlation between climatic factors and altitude with the spatial distribution of tree functional traits in the Subtropical Atlantic Forest. Deciduousness, symbiotic fixation of nitrogen (SNF), toothed leaf, spinescence and leaf area were more significantly associated with climatic drivers.
