Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

The Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Operational and environmental barriers to centralized composting in two small Brazilian municipalities: A longitudinal study

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Municipal solid waste management in small cities faces severe logistical and financial barriers regarding organic fraction treatment. This study evaluates biological selective collection in two small Brazilian municipalities (Astorga and Sabáudia), comparing dynamics between gated communities (GC) and public thoroughfares (PT) over an annual ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms. [PDF]

Environ Toxicol
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

International Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Functional architecture and cell wall composition of peltate scales involved in leaf water absorption

Frontiers in Plant Science
IntroductionFoliar water uptake (FWU) is a mechanism that contributes to plant water balance, especially in epiphytic environments. Morphological features such as the presence of peltate scales in bromeliads are adaptive traits for FWU. In this study, we
