Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Linking rivers, mixing faunas: How artificial connectivity between the Middle and Upper Paraná River basins shapes fish diversity in a tributary of the Itaipu Reservoir, Brazil. [PDF]

J Fish Biol
Abstract This work aimed to investigate the distribution and occurrence of fish species along the São Francisco Falso Braço Norte (SFFBN) River basin, a tributary of the Middle Paraná River basin now artificially connected to the Upper Paraná ecoregion, to evaluate how such connectivity may affect the biogeographic distribution and regional composition

Mapping the density of giant trees in the Amazon. [PDF]

New Phytol
Summary Tall trees (height ≥ 60 m) are keystone elements of tropical forests, strongly influencing biodiversity, carbon storage, and ecosystem resilience. Yet, their density and spatial distribution remain poorly quantified, especially in remote Amazonian regions, limiting our understanding of their ecological roles and contribution to forest–climate ...

A new species of inseminating catfish of the genus Tympanopleura (Siluriformes: Auchenipteridae) from the Ituxi River, Amazon River basin, northern Brazil, revealed by integrative taxonomy

Journal of Fish Biology, EarlyView.
Abstract A new species of the genus Tympanopleura is described from the Iquiri River, a tributary of the Ituxi River, a right‐bank tributary to the Purus River, Amazon River, northern Brazil. The new species is distinguished from all its congeners by a combination of features, such as the presence of an intensely pigmented square‐shaped blotch on the ...

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

Restoration Ecology, EarlyView.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

The Renal Function of the Wild Rodent Cerradomys goytaca Reveals Adaptations in the Mechanisms of Urinary Concentration and Solute Excretion

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 7, Page 772-784, August 2026.
Renal adaptations of Cerradomys goytaca associated with survival in its natural habitat. Graphical Abstract of the main renal physiological characteristics identified in C. goytaca. This species exhibits an increased kidney mass index, elevated urine osmolality, and enhanced tubular water reabsorption, indicating a higher capacity for water ...

Challenges and Advances Driving Studies on Aquatic Insects of the Order Coleoptera

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Aquatic beetles (Coleoptera) are known for their high taxonomic and ecological diversity and their sensitivity to environmental changes, making them key bioindicators in ecological assessments. However, numerous knowledge gaps persist globally.

Life‐History and Landscape Context Shaping the Spatial Genetic Structure of the Migratory Amazonian Fish Prochilodus nigricans

Freshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT The Neotropical migratory fish Prochilodus nigricans plays a critical ecological and socioeconomic role in the Amazon basin. Nevertheless, little is known about its populations and the genetic diversity pattern of the species. In light of this, the current study investigates the spatial genetic structure and diversity of P.

Acclimatisation duration, not just release type, drives post‐release settlement in a large‐scale carnivore reintroduction programme

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our study highlights that when acclimatisation periods are too short, the substantial economic and logistical investment in soft‐release protocols may fail to deliver the expected conservation gains. Therefore, defining evidence‐based acclimatisation periods that are long enough to promote settlement, yet compatible with logistical constraints, may ...

River conservation and restoration in croplands: can we improve the common agriculture policy as an instrument of practice?

Restoration Ecology, Volume 34, Issue S1, May 2026.
Abstract This study investigates the integration of river restoration with the Common Agricultural Policy (CAP), focusing on the differences between European Union (EU) and Portuguese documents regarding river restoration terms. A thematic content analysis highlights that despite the varying document sizes, the proportion of mentions related to river ...
