A new endemic pearl cichlid of the ‘Geophagus’ brasiliensis (Cichliformes: Cichlidae) species group from the Piranga River, upper Doce River basin, southeastern Brazil

Journal of Fish Biology, EarlyView.
Abstract A new species of pearl cichlid of the ‘Geophagus’ brasiliensis species group, endemic to the Piranga River, a major tributary of the upper Doce River basin in the state of Minas Gerais, southeastern Brazil, is herein described. The new species is delimited using an integrative approach, with molecular‐based species delimitation methods coupled

Feeding ecology of an Amazonian electric knifefish under altered flood‐pulse dynamics caused by hydroelectric damming

Journal of Fish Biology, EarlyView.
Abstract This study evaluated the effects of the controlled flood pulse on diet composition, trophic niche breadth and feeding intensity of Archolaemus janeae, an electric knifefish species with a restricted distribution in the Amazon Basin. Monthly samples were collected from December 2020 to November 2021 in the Volta Grande stretch of the Xingu ...

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

Restoration Ecology, EarlyView.
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 ...

Assessing functional diversity and composition using multispectral images in Atlantic Forest restoration sites

Restoration Ecology, EarlyView.
Abstract Introduction By focusing on the specific functional traits of species, we can better understand how ecosystems function and respond to environmental change. However, field measurements of functional traits can be time‐consuming and costly, whereas remote sensing data can serve as viable alternatives for studying biodiversity at larger scales ...

Limited contribution by non‐volant small mammals to regeneration in ironstone rocky outcrops

Restoration Ecology, EarlyView.
Abstract Introduction Animal‐mediated seed dispersal contributes substantially to natural regeneration in degraded areas. However, the role of seed dispersal by non‐volant small mammals (NVSM), mainly marsupials and rodents, in contributing to regeneration remains underexplored, especially in mountaintop, open‐canopy ecosystems.

Ultrasonographic Ocular Biometry of the Greater Caribbean Manatee (Trichechus manatus manatus)

Veterinary Ophthalmology, EarlyView.
ABSTRACT This study aimed to characterize the ocular biometry of the Trichechus manatus manatus applying B‐mode ultrasonography across different age groups. Twenty‐two animals were assessed employing a portable ultrasound device equipped with a linear transducer. Five ocular parameters were assessed: corneal thickness (CT), anterior chamber depth (ACD),

Shifting in the shadows: Morphofunctional variations of Miconia sellowiana Naudin (Melastomataceae) associated with cave environments

Plant Biology, Volume 28, Issue 2, Page 441-451, March 2026.
Cave environments filter plant traits, selecting thinner, smaller leaves with reduced photosynthetic and vascular structures. Abstract Caves present unique ecological conditions that influence the distribution and adaptation of species, yet studies on cave‐associated vegetation remain limited.

Trophic Ecology of Loggerhead Turtles (Caretta caretta) in Southern Brazil: Insights From Stable Isotopes

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the trophic ecology of loggerhead turtles recorded stranded along the Paraná coast in southern Brazil. Carbon and nitrogen stable isotopes were analysed in muscle tissues from 20 loggerhead turtles and in 69 specimens representing 12 prey species (molluscs, crustaceans and teleost fishes).

Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...
