First assessment of brush‐harvested native seed mixes in southern Brazilian grasslands

Restoration Ecology, EarlyView.
Abstract Introduction The restoration of grassland ecosystems in southern Brazil remains limited by the absence of a structured supply chain for native seeds and seedlings. Objectives Here, we present the first evaluation in Brazil of mechanized, multi‐species seed harvesting from native grassland remnants using a brush harvester.

Neotropical Snakes Reveal Different Geological Times for Dispersal Corridors Between Amazon and Atlantic Forests

Zoologica Scripta, EarlyView.
ABSTRACT Three forested dispersal corridors have been proposed within the diagonal of open/dry landscapes in South America and the relative importance of each one has been the subject of debate for forest organisms. We analysed the biogeographical history of three snake genera (Bothrops, Philodryas, and Micrurus) from different families (Viperidae ...

Wildfire in the Surrounding Landscape Alters Limnological Conditions and Plankton Communities in a Tropical Reservoir

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Wildfires are becoming increasingly frequent and severe as a consequence of climate change. Their impacts on terrestrial ecosystems and on the atmosphere include the release of gases and ash, as well as enhanced soil susceptibility to erosion and the downstream transport of materials into aquatic systems.
