Climate‐driven resource availability drives medium‐ and broad‐scale temporal changes in owl–prey interactions over 24 years in a semi‐arid ecosystem

Ecography, EarlyView.
Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Biogeography of the lizard genus Tropidurus Wied-Neuwied, 1825 (Squamata: Tropiduridae): distribution, endemism, and area relationships in South America.

PLoS ONE, 2013
Based on comprehensive distributional records of the 23 species currently assigned to the lizard genus Tropidurus, we investigated patterns of endemism and area relationships in South America. Two biogeographic methods were applied, Parsimony Analysis of

The Impact of Domestic Public Health Spending on Health Outcomes in Sub‐Saharan Africa: Evidence From Disability‐Adjusted Life Years

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Sub‐Saharan Africa (SSA) continues to experience a high and uneven disease burden, mainly from HIV/AIDS, tuberculosis, and malaria. As external funding declines, the strategic allocation of domestic public health spending (DPHS) becomes crucial.

Invasive plant distributions recapitulate patterns found in native plant assemblages in a heterogeneous landscape

Ecosphere, 2015
Diverse alien and native floras of the same region provide a good opportunity to test the influence of environmental variables in structuring of plant assemblages because both can be considered as a replicates of the assembly process under identical ...

Pollen Morphology of Crucianella L. (Rubiaceae) Based on Light and Scanning Electron Microscope Data and Implications for Taxonomy

Microscopy Research and Technique, EarlyView.
This study provides the palynological analysis of 12 Crucianella L. taxa using LM and SEM. Variations in pollen size, aperture number, and exine ornamentation were identified as key traits, demonstrating their taxonomic value for distinguishing closely related species and subspecies within the genus. ABSTRACT Crucianella L.

Distribution patterns of Neotropical primates (Platyrrhini) based on Parsimony Analysis of Endemicity

Brazilian Journal of Biology
The Parsimony Analysis of Endemicity (PAE) is a method of historical biogeography that is used for detecting and connecting areas of endemism. Based on data on the distribution of Neotropical primates, we constructed matrices using quadrats, interfluvial

Trends in hospitalizations for vaccine‐preventable diseases in the United States from 2014 to 2024

Journal of Hospital Medicine, EarlyView.
Abstract Background and Objectives Vaccination rates have declined in recent years, resulting in outbreaks of vaccine‐preventable diseases (VPDs) among children. We aimed to evaluate VPD hospitalization rates from 2014 to 2024 and to report associated trends in outcomes including intensive care utilization, mortality, readmissions, and costs.

Updated checklist and identification of areas of endemism of benthic amphipods (Caprellidea and Gammaridea) from offshore habitats in the SW Gulf of Mexico

Scientia Marina, 2006
An updated checklist of the benthic amphipods associated with soft bottoms in the SW Gulf of Mexico has been made and the areas of endemism have been identified. Amphipods were collected in a depth interval of 25 to 3700 m during six cruises from 1994 to

Taxonomy and phylogeny of the intercontinental disjunctive ferns: series Reniformia Adiantum

Nordic Journal of Botany, EarlyView.
There are disputed opinions about the three taxa of series Reniformia, namely A. nelumboides X.C.Zhang (A. reniforme var. sinense Y.X.Lin), A. reniforme var. reniforme, and A. reniforme var. asarifolium (Willd.) R. Sim, owing to their similar morphology but intercontinental disjunctive distribution and close lineage with the series Venusta (only ...

Diagnosis of Portal Hypertension: Advancing Towards Non‐Invasive Solutions

Portal Hypertension &Cirrhosis, EarlyView.
This review systematically summarizes a full spectrum of non‐invasive diagnostic approaches for portal hypertension (PH), including imaging modalities, elastography, serum biomarkers, composite scoring systems and endoscopic ultrasound‐guided portal pressure gradient (EUS‐PPG), and analyzes their performance across different liver disease etiologies ...
