Quantification and visualization of 3D facial aging in individuals of European ancestryNARA Subscribed
Facial features undergo continuous transformations across the lifespan. This study quantified and visualized the effects of aging on facial morphology in individuals of European ancestry. Three-dimensional facial photographs of 4,038 individuals (1,455 males and 2,583 females), aged 5 to 85 years and of European descent, were analyzed. Morphological changes in the face were modeled using kernel linear regression, with a focus...
During the preventive archaeological excavation in the cellar of the site of petite Rue des Bouchers in the historical centre of Brussels (Belgium), the waterlogged remains of a thirteenth century AD sunken byre (potstal) were discovered. The exceptional preservation instigated a multiproxy approach, including micro-archaeology, micromorphology, phytolith and endoparasite egg analysis on thin sections, palynology and the study...

SNAPSHOT USA 2019–2023: The First Five Years of Data From a Coordinated Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multicontributor 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 specie...
Trade‐offs play pivotal roles in the ecology and evolution of natural populations. However, trade‐offs are probably not static, invariant relationships. Instead, ecological factors can shift, alter, or reverse the relationships underlying trade‐offs and create critical genotype × environment (G × E) interactions. But which ecological factors alter trade‐offs or create G × E interactions, and why (mechanistically) do they do th...
Friendly competition: evidence for a dilution effect among competitors in a planktonic host–parasite systemNARA Subscribed
The “dilution effect” concept in disease ecology offers the intriguing possibility that clever manipulation of less competent hosts could reduce disease prevalence in populations of more competent hosts. The basic concept is straightforward: host species vary in suitability (competence) for parasites, and disease transmission decreases when there are more incompetent hosts interacting with vectors or removing free‐living stage...
Epidemiologists increasingly realize that species interactions (e.g. selective predation) can determine when epidemics start and end. We hypothesize here that resource quality can also strongly influence disease dynamics: epidemics can be inhibited when resource quality for hosts is too poor and too good. In three lakes, resource quality for the zooplankton host ( Daphnia dentifera ) was poor when fungal epidemics ( Metschniko...
Species interactions may profoundly influence disease outbreaks. However, disease ecology has only begun to integrate interactions between hosts and their food resources (foraging ecology) despite that hosts often encounter their parasites while feeding. A zooplankton–fungal system illustrated this central connection between foraging and transmission. Using experiments that varied food density for Daphnia hosts, density of fun...
