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...
More inclusive conservation approaches are needed to achieve the dual goals of justice and sustainability. This imperative requires developing new strategies to adapt extant models like conservation-based tourism in protected areas to incorporate more plural perspectives. We studied guided tours in Tierra del Fuego National Park, Argentina to assess how nature and people-nature relationships were (re)produced. Specifically, we...
Predictive validation of the repeated low-dose reserpine rodent model of parkinsonismNARA Subscribed
L-DOPA (LD) is the gold-standard treatment of motor symptoms in Parkinson’s disease (PD), conventionally used to prove the predictive value of PD animal models. This study aimed to investigate the predictive validity of an adaptation of the conventional reserpine model of PD: the repeated low-dose reserpine administration in rodents, which promotes progressive motor impairment in catalepsy, vacuous chewing behavior tests, and...
In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction. The Scolebythidae, a small family of stinging wasps, represents an interesting group to study the application of the morphological clock due to their limited ex...
Evapotranspiration Everywhere, All the Time: Towards a Unified View From Earth ObservationNARA Subscribed
Scientists want to know everything, everywhere, and all the time. This is particularly true in Earth science, where we seek to understand processes that span from the molecular to the planetary scale in how the world works, how it affects us, and how we impact it—especially the water cycle. Evapotranspiration (ET) was the last component to be measured in closing the water cycle: for decades, closing the water budget meant addi...
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...
Aim The temperature‐size rule is often described as a reduction in ectothermic asymptotic or maximum body size with warming. Although this coincides with the expectation that faster growth under warming would lead to larger sizes early in life but smaller sizes later in life, there remain few tests of changes in size across ontogeny. Here, we use > 99,000 observations of weight‐at‐age of commercially important fishes over 25 y...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the Shorebird Science and Conservation Collec...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
