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...
Importance of phenomena expected to modify population trends of a threatened saltmarsh breeding bird communityNARA Subscribed
Salt marshes in the northeastern United States support several specialized breeding bird species that are threatened by sea level rise (SLR) and coastal development, processes that drive habitat change and fragmentation. There have been rapid, widespread declines in some species, but mechanisms driving population change and whether declines continue remain unclear. We examined the influence of phenomena expected to modify salt...
Transient population dynamics impede restoration and may promote ecosystem transformation after disturbanceNARA Subscribed
The apparent failure of ecosystems to recover from increasingly widespread disturbance is a global concern. Despite growing focus on factors inhibiting resilience and restoration, we still know very little about how demographic and population processes influence recovery. Using inverse and forward demographic modelling of 531 post‐fire sagebrush populations across the western US, we show that demographic processes during recov...
Restoration and rehabilitation of native vegetation in dryland ecosystems, which encompass over 40% of terrestrial ecosystems, is a common challenge that continues to grow as wildfire and biological invasions transform dryland plant communities. The difficulty in part stems from low and variable precipitation, combined with limited understanding about how weather conditions influence restoration outcomes, and increasing recogn...
Elephants in the understory: opposing direct and indirect effects of consumption and ecosystem engineering by megaherbivoresNARA Subscribed
Positive indirect effects of consumers on their resources can stabilize food webs by preventing overexploitation, but the coupling of trophic and non‐trophic interactions remains poorly integrated into our understanding of community dynamics. Elephants engineer African savanna ecosystems by toppling trees and breaking branches, and although their negative effects on trees are well documented, their effects on small‐statured pl...
