Nocturnal nitrogen oxides at a rural mountain-site in south-western Germany [PDF]

open access: yes, 2010
A new, two-channel instrument for simultaneous NO3 and N2O5 monitoring was used to make the first comprehensive set of nocturnal NOx measurements (NO, NO2, NO3 and N2O5) at the Taunus Observatory, a rural mountain site (Kleiner Feldberg) in South-western

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

Interspecies synchrony in departure decisions from stopover sites: evidence using a multi‐species capture–recapture model

open access: yesOikos, EarlyView.
During migration, migratory bird species often aggregate at the same stopover sites due to geographical features that channel migratory routes (coasts, valleys) or locally abundant food resources (e.g. reedbeds, fruiting bushes). In migration ecology, however, stopover behavior is often studied on a single species, limiting the generality of inferences

A review and meta‐analysis of host‐plant selection by lepidopteran larvae: no evidence of diet breadth constraints on larval decision‐making

open access: yesOikos, EarlyView.
Information processing by herbivorous insects can impair the accuracy of decision‐making during host‐plant selection. Consequently, insects with a narrower diet breadth are expected to be more accurate decision‐makers, as they cope with a smaller set of relevant stimuli.

Seasonal variation in the ultrasonic vocal activity of Humboldt's flying squirrel (Glaucomys oregonensis)

open access: yesEcology and Evolution
Most mammals rely on vocal communication to increase survival and reproductive success. While the functions of audible vocalizations have been well‐studied across mammal species, ultrasonic vocalizations in small mammals outside of bats are less ...

Biomass and abundance trends diverge as the North American avifauna undergoes widespread demographic declines

open access: yesOikos, EarlyView.
Biomass is a fundamental metric in ecology and conservation, widely used to inform questions related to community structure, energetics and function. Despite the ubiquity of biomass in broader ecological research, avian ecology and conservation has been based primarily on measures of abundance.

Lifting the Veil of Darkness: Thermal Technology Facilitates Collection of Flight‐Initiation Distances by Night

open access: yesEcology and Evolution
Flight‐Initiation Distance (FID)—a direct measure of an individual animal's escape response—is a widely used method to study escape ecology in fauna. The technique has primarily been applied to bird species that are active by day.
