The Introduction of Chickens Into Norway and Their Early Use: New Evidence From the Borgund Kaupang

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT Chickens reached areas of northern Europe by the 6th to 5th century bce, but their dispersal into Scandinavia appears delayed. Here we present a thorough assessment of chicken remains recovered from Borgund, a deserted late Viking Age–Medieval urban site located near Ålesund on the west coast of Norway. Direct and indirect dating of 20 chicken

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

open access: yesOikos, 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

open access: yesOikos, 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
