Klebsiella quasipneumoniae is a Gram-negative, non-motile, capsulated, facultative anaerobic rod within the K. pneumoniae species complex (KpSC) and is increasingly recognized as an opportunistic pathogen associated with bloodstream infections, urinary tract infections (UTIs), and other clinically significant conditions. Because it shares many phenotypic characteristics with K. pneumoniae , accurate diagnosis remains challengi...
Intertropical convergence zone and El Niño Southern oscillation controls on late Holocene rainfall variability in PalauNARA Subscribed
The Tropical West Pacific is an understudied region in environmental and archaeological studies when compared to continental regions. The unique geologies, climate systems, and ecological dynamics in the Tropical West Pacific greatly limit the transferrability of palaeoenvironmental proxies established from studies outside of this region. To address this gap, we present a ~5600 yr multi-proxy record of environmental change fro...
Alterations of cryptogam communities over one decade of time on King George Island, AntarcticaNARA Subscribed
Antarctica’s ice-free areas are mainly colonized by cryptogamic communities, which are known to be sensitive indicators of environmental change. Despite numerous monitoring-related studies, published research on medium-term cryptogam cover changes is limited. With this study, we aimed to investigate compositional and structural changes in cryptogamic communities over a decade near the Polish Arctowski Antarctic Station. Here,...
Reef shape, position and flow regime mediate bleaching severity in a southern Great Barrier Reef platform reef systemNARA Subscribed
Coral bleaching represents a primary threat to coral reefs worldwide. Patch reefs in lagoon systems are highly susceptible to bleaching due to shallow, high residence water, high light intensity and reef edge effects. Geomorphic, spatial and hydrodynamic factors are important in modifying environmental stressors, yet their interacting roles in influencing bleaching responses are not well understood. In this study, we investiga...
Surface slicks structure microbial and viral neuston in relation to biogeochemical conditionsNARA Subscribed
The sea‐surface microlayer (hereafter microlayer), which forms the interface between the ocean and atmosphere, plays a key role in nutrient cycling and microbial dynamics. Coastal slicks, which are viscous and biogenic surface films, often serve as hotspots for microbial activity, yet their structure and interactions remain incompletely understood. Here, we investigated viral and microbial abundance, surfactants, dissolved org...
Reliable developmental benchmarks are essential for synchronizing incubation and first-feeding decisions in striped bass (Morone saxatilis) hatcheries, yet existing references are incomplete, outdated, or difficult to apply across variable temperature regimes. We developed contemporary embryo and larval developmental staging guides for striped bass using digital imaging and degree day standardization and paired these guides wi...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
A systematic review of associations between functional connectivity, mood and cognition in patients with irritable bowel syndromeNARA Subscribed
Irritable bowel syndrome (IBS) affects 9.3%–35.5% of the population, with women at greater risk. It is often comorbid with anxiety, depression, and cognitive dysfunction. Understanding the neural mechanisms underlying these comorbidities is crucial for identifying IBS pathology and developing targeted treatments. Functional magnetic resonance imaging (fMRI) offers valuable insights into brain connectivity and psychopathology....
The complex population structure of Tamanend's bottlenose dolphins ( Tursiops erebennus ) along the U.S. Mid‐Atlantic coast complicates assessment of their bycatch. To improve our understanding of the stock identity of individual dolphins taken as bycatch in this region, we compared images of the dorsal fins of bottlenose dolphins that stranded with evidence of fishery interactions (FI+) to the Mid‐Atlantic Bottlenose Dolphin...
Accurate prediction of community assembly is a central goal in ecology but is challenging because assembly is governed by numerous mechanisms. Few theoretical models explicitly incorporate or test multiple mechanisms at once. We empirically tested the predictive performance of a plant community assembly model built using all possible combinations of four ‘mechanisms’ (soil resource competition, dispersal and colonisation, spat...
New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target. However, there is a lack of species occurrence data to support evidence of where biodiversity can be best protected. To address t...
