Temporal and Ontogenetic Changes in Feeding Ecology of a Characid From Karst Dolines of the Neotropics

open access: yesEcology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT Environmental and biological factors strongly shape fish diets, yet little is known about such influences in flooded Karst Dolines of the Neotropical region. This study examined the diet of Deuterodon luetkenii and assessed its temporal and ontogenetic variation in Lagoa Misteriosa, a karstic lagoon. Fish were sampled bimonthly over 1 year and

A pedo‐isotopic approach to study sandy soils of the Brazilian Cerrado in Piauí State

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Sandy soils dominate Brazil's Cerrado biome in Piauí State, yet their organic carbon (OC) stabilization mechanisms and landscape‐driven pedogenesis remain poorly understood. To clarify this topic, the present study proposes a pedo‐isotopic approach to characterize six representative Brazilian Cerrado soils derived from sedimentary rocks in ...

Distinct Intra‐ and Interspecific Foraging Patterns of Stingless Bee Species as a Conservation Tool

open access: yesBiotropica, Volume 57, Issue 5, September 2025.
In this study, we examined the foraging patterns of three rescued stingless bee species in the Bolivian Yungas using melissopalynology and plant–pollinator network analysis. We found distinct floral foraging patterns both within and among three stingless bee species in the Bolivian Yungas, suggesting niche partitioning at multiple levels.

Insights Into the Feeding Ecology of Young‐of‐the‐Year Bigeye Tuna (Thunnus obesus) in the Southwestern Atlantic Ocean

open access: yesFisheries Oceanography, Volume 34, Issue 5, Page 121-127, September 2025.
ABSTRACT Bigeye tuna (Thunnus obesus) is among the most prized tuna species sustaining fisheries worldwide. However, information on the feeding habits for the species is mostly restricted to the size range harvested by commercial fisheries. In this study, we report the diet composition of juvenile bigeye tuna schooling near the surface at night in the ...

Origins and Diversification of the Caatinga Dry Forest Endemic Avifauna

open access: yesJournal of Biogeography, Volume 52, Issue 9, September 2025.
ABSTRACT Aim Understanding the geographic origin of lineages is critical to comprehending their biogeographical and evolutionary histories and the historical connections among biomes. In northeastern Brazil, the Caatinga dry forest represents the largest and most biologically diverse patch of Seasonally Dry Tropical Forest in the Neotropics.
