Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

open access: yesWildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

Micro‐habitat selection by boreal woodland caribou improves access to food

open access: yesWildlife Biology, EarlyView.
Bio‐logging sensors attached to radiotelemetry receivers have great potential to transform our understanding of the ecological, physiological, and energetic constraints that shape patterns of wildlife movement under field conditions. We used video camera collars to assess microhabitat selectivity by woodland caribou Rangifer tarandus in boreal forests ...

“Reversed” Krebs Cycle Can Feed Tumors [PDF]

open access: yesCancer Discovery, 2012
Abstract Certain cancer cells that have mutations preventing them from using the normal oxidative pathway of the Krebs cycle can ramp up the withdrawal of various intermediates from the Krebs cycle to churn out macromolecular precursors essential for rapid cell growth.

The (un)importance of unemployment fluctuations for welfare [PDF]

open access: yes
This paper develops a real business cycle model with labor market search and matching frictions, which endogenously links both the cyclical fluctuations and the mean level of unemployment to the aggregate business cycle risk.

The Growing Pain of Animal Welfare Weaponization: Get the Ghost Out of the Machine

open access: yesZoo Biology, EarlyView.
ABSTRACT Managing for positive animal welfare is recognized as a fundamental zoo and aquarium practice. Indeed, many zoo and aquarium associations now have expectations that their members demonstrate achievement of some level of positive welfare for their charges.

Trade‐offs across life history stages and social association types shape winter communal roosting in a long‐lived raptor

open access: yesJournal of Animal Ecology, EarlyView.
Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...
