Detected Shifts Towards Drought‐Adaptive Strategies in the Amazon Forest Over the Last Four Decades [PDF]

Global change biology.
Amazon forests are facing hotter, drier conditions, and we used 40 years of satellite data to look for early signs of ecological change. Combining satellite observations with leaf measurements from more than 3000 trees, we show that many forests now show smaller dry‐season fluctuations in canopy colour—especially in the southern and eastern Amazon ...

Estimating costs of ecological restoration across degradation scenarios in South Brazilian grasslands

Restoration Ecology, EarlyView.
Abstract Introduction Grassland ecosystems are among the most threatened worldwide, and the Campos Sulinos—a region of subtropical grasslands in southern Brazil—experiences degradation driven by multiple factors. This study provides initial cost estimates for different restoration approaches, offering guidance for technical and budgetary planning ...

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

Zoologica Scripta, EarlyView.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

The Role of Gene Flow in the Diversification of the Monkey Treefrog Complex Across the South American Dry Diagonal

Zoologica Scripta, EarlyView.
ABSTRACT Understanding Neotropical megadiversity remains challenging due to fundamental taxonomic issues, including identifying and describing cryptic species and their distribution, and the limited knowledge of key factors driving biological diversification. Such challenges are especially prominent in diverse clades with high levels of cryptic species,

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...

Selection of suitable additives for seed pelletizing to enhance germination and growth of Onobrychis viciifolia in restoration of semi‐arid degraded rangelands

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Despite direct seeding, seed pelletizing with useful materials is one of the effective methods to improve plant growth. This experiment assessed the impacts of different additives used in seed pelletizing on germination and growth of Onobrychis viciifolia at a degraded semi‐arid rangeland.
