Adaptive sampling for ecological monitoring using biased data: a stratum‐based approach

Oikos, EarlyView.
Indicators of biodiversity change across large extents of geographic, temporal and taxonomic space are frequent products of various types of ecological monitoring and other data collection efforts. Unfortunately, many such indicators are based on data that are highly unlikely to be representative of the intended statistical populations.

Quantifying community keystoneness in metacommunities under disturbance

Oikos, EarlyView.
Understanding how metacommunities respond to natural and anthropogenic disturbances is a key objective in ecology. In this study, we introduce an analytical framework to identify communities whose extirpation triggers stronger (hereafter keystone communities) or weaker (hereafter idle communities) cascading effects on extinction and colonization events

Investigating the Effects of Functionalized Single Wall Carbon Nanotubes on the Cure Behavior of a Carbon/Epoxy Prepreg System by an Optimized Parameter Approach

Polymer Composites, EarlyView.
Mathematical Modeling of the Effect of Carbon Nanotubes on the Cure Behavior of a Carbon/Epoxy Prepreg Syste. ABSTRACT Carbon/Epoxy composite materials are used in a wide range of applications due to their superior performance. However, their properties are strongly related to cross‐linking reactions occurring during the curing process, and a prior ...
