Nesting Mottled Duck ( Anas fulvigula ) selection of ungrazed grasslands in southwestern Louisiana is associated with increased nest survival

Avian Conservation and Ecology
Nest site selection is a discrete and often repeated choice, and individuals should select nest sites that maximize reproductive success and thus increase fitness.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Nest attendance and thermoregulation behaviors correlate with nest site microclimate in breeding dark-capped bulbul, Pycnonotus tricolor

Frontiers in Ecology and Evolution
Temperatures within bird nests should not become too high to prevent adults and their offspring from overheating. Reproducing birds can influence nest temperature relative to ambient temperature through nest-site selection and control egg temperature ...

Habitat selection and reproduction of red-backed shrikes (Lanius collurio) in relation to abundance of potential avian nest predators [PDF]

, 2010
Many studies of farmland bird species have related abundance of species to different habitat variables, whereas few studies have incorporated the effects of predation on habitat selection. However, it is generally assumed that prey species select habitat

Does nest predation affect nest-site selection in larks ?

, 1996
Nest-site selection may affect nest predation rates. In this paper we analyse nest-site habitat selection in the Thekla and Lesser Short-toed larks, and compare the habitats of successful and predated nests. Both species have a preference for safe sites.

Arterial Spin‐Labeling MRI at the Cortical‐CSF Interface: A Novel Biomarker in Alzheimer Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background/Objective Arterial spin‐labeling (ASL) MRI can measure perfusion signal adjacent to CSF spaces and may provide information regarding CSF‐adjacent water transport physiology. We developed an automated pipeline to extract cortical‐CSF interface (IF) perfusion for comparison between Alzheimer disease (AD) and cognitively normal ...

The Comprehensive Live Cell‐Based Cytotoxicity Assay for Monitoring Disease Activity and Guiding Rescue Therapy in Acute Attacks of NMOSD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuromyelitis optica spectrum disorder (NMOSD) is a devastating neurological disease that lacks serological biomarkers that can accurately reflect disease activity. We established a live cell‐based assay (LCBA) using serum with endogenous complement to quantify the overall cytotoxicity, offering a novel functional tool for monitoring

Nest site selection by Holarctic waterfowl : a multi-level review

, 2014
Because of birds’ mobility, behaviour and many species’ migratory nature, they select repeatedly and spatially among habitats and have been central figures in studies of avian breeding habitat selection during the 20th and 21st centuries.

Macro- and Microhabitat Predictors of Nest Success and Hatchling Survival in Eastern Box Turtles (Terrapene carolina carolina) and Spotted Turtles (Clemmys guttata) in Oak Savanna Landscapes

Frontiers in Ecology and Evolution, 2022
Differing selection pressures on stationary nest contents compared to mobile offspring mean that the nest-site characteristics resulting in the highest nest success may not be the same characteristics that result in the highest survival of juveniles from

Data‐Driven SuStaIn Model of Disability Progression in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether ordinal Subtype and Stage Inference (SuStaIn) applied to routine ALSFRS‐R item scores can identify reproducible disability progression patterns in amyotrophic lateral sclerosis (ALS) and provide clinically meaningful staging.
