Bioindicators are widely used to describe environmental impacts through rapid and cost-effective assessments. However, identifying them at the species level with detailed quantitative sampling is time-consuming, expensive, and requires specialized knowledge. This study evaluated, using planktonic ciliates, taxonomic and numerical sufficiency approaches to test whether higher taxonomic levels and different numerical resolutions...

Hyperostosis is a non‐pathological condition widely reported in marine teleosts, yet its developmental dynamics and underlying drivers remain poorly understood. This study investigates the ontogenetic progression and anatomical distribution of hyperostosis in Caranx hippos based on a growth series of 39 specimens collected along the Brazilian coast. Individuals were categorised into two size classes (class 1 C. hippos , with m...

Pasture-based dairy systems require well-adapted forage cultivars and appropriate grazing management to sustain milk production while maintaining favorable sward structure. The objective of this study was to evaluate the performance of Holstein × Gyr crossbred cows and the productive and structural characteristics of Paiaguás grass pasture ( Urochloa brizantha cv. BRS Paiaguás) and Ipyporã grass pasture ( Urochloa brizantha ×...

The structuring of aquatic communities depends on a set of factors, such as abiotic variables, biotic interactions, and spatial processes related to species dispersal. However, the influence of these predictors varies across different spatial scales, organism groups, and ecosystems. Environmental and spatial processes are key drivers of beta diversity, and therefore this review aimed to synthesize the literature on the relativ...

Hyperostosis is a natural phenomenon characterised by bone thickening and remodelling that occurs more frequently in wild marine teleosts than in captive populations. Within the family Carangidae, species of the genus Trachinotus are among the most frequently affected, although expression patterns vary widely among taxa. This study provides a comparative assessment of hyperostosis across four Trachinotus species from the south...

Aim We investigate the distribution of dispersal modes — endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and dispersal agents (e.g., the main vectors moving seeds). We expected climate to be the mai...

The Pantaneiro sheep is a locally adapted genetic resource shaped by the seasonal flooding, thermal stress, and heterogeneous forage availability of the Brazilian Pantanal. Characterizing its morphological structure using objective and field-applicable traits is essential for standardized phenotyping and conservation-oriented breeding strategies. This study evaluated 211 Pantaneiro ewes raised under semi-extensive management t...

Recent studies have shown that a few tree species dominate abundance and carbon storage in undisturbed Amazonian forests. However, this pattern remains poorly understood in forests regrowing after deforestation. Understanding dominance patterns in secondary forests is important as it could improve insights into their functioning and guide management and restoration efforts. We used unweighted and novel plot‐weighted approaches...

Mining activities have substantially altered Amazonian watercourses. Odonata are sensitive to environmental changes and efficient bioindicators because they are highly responsive to conditions in riparian and aquatic habitats. Therefore, our objectives were to assess the changes associated with a slurry pipeline on Amazonian streams and to determine whether those changes altered Odonata assemblage structure. We also sought to...

The Cerrado biome, spanning ~2 million km 2 , is one of the most extensive and biodiverse tropical savannas, yet it is paradoxically dominated by only 30 hyperdominant tree species (~2% of all species, > 50% of all stems). However, their vulnerability to climate change and the effectiveness of current conservation efforts remain uncertain. By combining (i) species distribution models calibrated with edaphic‐climatic predictors...
