Molecular phylogenetics suggest Osmiopsis (Asteraceae) could be a rare inter-subtribal hybrid genus on HispaniolaNARA Subscribed
Osmiopsis (Asteraceae, Eupatorieae) is endemic to Hispaniola and one of the seven genera of subtribe Praxelinae. When Osmiopsis was established in 1975, the authors hypothesized it was a hybrid and proposed Chromolaena (subtribe Praxelinae) and Koanophyllon (subtribe Critoniinae) as putative parent genera. To clarify its origin, a phylogenetic investigation of subtribe Praxelinae, reconstructed within a matrix of 80 genera/202...
After harvesting the berries from the elderberry plant, the remaining plant residue can serve as a fodder for ruminants. A laboratory silo experiment was conducted to determine the effect of a) ensiling immediately after cutting [38–47% dry matter (DM), or after wilting (47–54% DM)] and b) ensiling dates: early post-harvest, mid post-harvest, and late post-harvest on the nutritive values and fermentation parameters of ensiled...
Cognitive Outcomes Following Paediatric Mild Traumatic Brain Injury: A Systematic Review and Meta-Analysis of Studies up to 2025NARA Subscribed
The purpose of this review was to provide a systematic and quantitative summary of recent literature relating to cognitive outcomes following paediatric mild traumatic brain injury (mTBI). Variable findings and diverse methodologies have thus far made it difficult to meaningfully integrate the extant literature. In this context, there is a need to examine the factors that define heterogeneity in this population and to critical...
Dissolved oxygen (DO) dynamics in estuarine ecosystems are shaped by both anthropogenic activities and climate variability, which jointly influence oxygen concentrations and overall ecosystem health. This study examined temporal and spatial variations in DO across three coastal sectors in Eastern South America. DO levels were classified as hypoxia (<2.0mgL-¹),intermediate(2.0–4.0mgL¹), and optimum (>4.0mgL-¹).Hypoxia was assoc...
Amazon Dry Season Will Lengthen Under Future ClimateNARA Subscribed
The Amazon rainforest is a key component of the Earth system, regulating regional climate, sustaining high biodiversity and carbon stocks. However, it is threatened by climate and land‐use changes. In recent decades, the region has experienced intensified droughts and heatwaves, trends expected to worsen under future warming. In this study, we assess how the timing, length, and spatial distribution of the dry season across the...
