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

Plant Biology, EarlyView.
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.

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),

Dengue, chikungunya and Zika virus surveillance in blood donors in Brazil, 2019–2021

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Arbovirus infections are a major public health concern in Brazil and an ongoing blood safety concern. Periodic outbreaks of such infections are common in the general population. This study aimed to establish the rates of dengue, chikungunya and Zika virus (DENV, CHIKV, ZIKV) RNAemia among blood donors at six public ...

Historical Climate and Biome Association Drove Phylogeographic Patterns in the Dwarf Swamp Frog (Anura: Leptodactylidae)

Zoologica Scripta, EarlyView.
ABSTRACT South America, a region with high biodiversity, has been profoundly shaped by geological events during the Miocene and Pliocene, as well as by climatic changes in the Pleistocene, leading to complex phylogeographic patterns. The diverse biomes and the biotic exchanges between them, particularly between the Amazon and the Cerrado, have ...

Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...
