A Long‐Standing Taxonomic Puzzle: Species Delimitation and Phylogenetic Analysis Reveal New Findings in Neogoniolithon (Spongitidaceae, Corallinophycidae and Rhodophyta) From the Southwestern Atlantic

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.
ABSTRACT In the first study on Neogoniolithon species for the Southwestern Atlantic Ocean, based on both molecular (COI‐5P, psbA and SSU rDNA) and morpho‐anatomical data, three taxa were identified for the Brazilian coast, including two new species. DNA‐based species delimitation methods distinguished Neogoniolithon crypticum sp. nov.

Ontogenetic Changes in Feeding Behaviors in Tufted Capuchins

open access: yesAmerican Journal of Biological Anthropology, Volume 187, Issue 4, August 2025.
ABSTRACT Objectives Wild juvenile capuchins exhibit lower feeding success than adults, particularly for mechanically challenging foods, but ontogenetic changes in oral food processing behaviors related to this reduced success are unknown. We test how oral food processing efficiency varies across development in an experimental setting in tufted ...

Exploring the Selective Distribution of PE‐g‐AA in the PA6/AES Blend: Rheological, Mechanical, Thermal, Thermomechanical Properties, and Morphology

open access: yesPolymers for Advanced Technologies, Volume 36, Issue 7, July 2025.
ABSTRACT Polymeric blends are essential in the plastics processing industry for offering tailor‐made properties such as durability, flexibility, and toughness, and expanding applications. This study investigated, for the first time, the use of polyethylene grafted with acrylic acid (PE‐g‐AA) as a compatibilizer in blends of polyamide 6 (PA6) with ...

PicoCam: High‐resolution 3D imaging of live animals and preserved specimens

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 11, Page 1980-1989, November 2024.
Abstract The PicoCam system is a multi‐camera photogrammetry rig used for generating high‐resolution 3D models of animals in the field, or preserved specimens in laboratory or museum settings. The digital measurement of 3D models is increasingly useful for studying body shape. However, methods that capture sub‐millimetric detail often do so at the cost

O Quadro de Raciocínio Clínico Bobath: Uma abordagem de ciência de sistemas para a complexidade das condições do neurodesenvolvimento, incluindo a paralisia cerebral

open access: yesDevelopmental Medicine &Child Neurology, Volume 66, Issue 8, Page e102-e111, August 2024.
Esta revisão descreve um modelo de prática pediátrica recomendada do Bobath, o Quadro de Raciocínio Clínico Bobath (QRCB), e explica como esse conhecimento contribui para a área de habilitação em distúrbios pediátricos. A ciência de sistemas proporciona uma nova maneira de concetualizar a paralisia cerebral como uma condição complexa.

Amplification of Ovis aries papillomavirus type 2 DNA from an ovine cutaneous fibropapilloma

open access: yesVeterinary Dermatology, Volume 35, Issue 2, Page 226-229, April 2024.
Seven of 60 Perendale sheep within a flock developed single or multiple exophytic masses on their distal hind limbs. A mass was excised from one sheep and histological evaluation revealed epidermal and mesenchymal proliferation, papillomavirus‐induced keratinocyte changes and marked keratohyalin clumping.
