Temporal Changes in Land Use Highlight the Vulnerability of Highland Grasslands in Protected Areas in Southern Brazil

Biotropica, Volume 58, Issue 1, January 2026.
Subtropical Highland Grasslands showed greater net conversion than Mixed Ombrophilous Forest across our study PAs. In one PA created to conserve Highland Grasslands, net grassland loss inside the PA exceeded loss in adjacent buffer zones during the study period.

Structural and Functional Properties of Araucaria araucana and Araucaria angustifolia Seed Proteins as a Plant‐Based Food Source

Sustainable Food Proteins, Volume 3, Issue 4, December 2025.
Morphologically, A. angustifolia seeds were significantly larger, while A. araucana exhibited more regular, triangular shapes. Proximate composition revealed a carbohydrate‐rich profile in both species, with a significantly higher lipid content in A. araucana. Amino acid analysis showed similar profiles, with high levels of aspartic and glutamic acids.

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.
