Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Iterative phase retrieval in macromolecular crystal diffraction using the gradients of intensities
Journal of Applied Crystallography, EarlyView.Incorporating molecular intensity gradients into an iterative projection algorithm enables model‐free electron‐density reconstruction even for low‐solvent macromolecular crystals.Iterative phase retrieval (IPR) offers a model‐independent route to crystallographic structure determination but is fundamentally limited by the sampling of the diffraction ...

Playing with fire: Wolf response to active wildfires, fire fronts and smoke
Journal of Animal Ecology, EarlyView.This study is one of the first, to our knowledge, to explicitly examine fine‐scale behavioural responses of a large carnivore to actively burning wildfires, fire fronts and smoke. The study found that wolves balanced the potential risks and benefits associated with wildfires, with implications for predator–prey dynamics in fire‐prone regions.

Journal of Animal Ecology, EarlyView.Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...

British Journal of Management, EarlyView.Abstract This paper examines how, and under what conditions, the increasing presence of highly skilled local employees (HSLEs) within subsidiaries of developed‐country multinational enterprises (DCMNEs) influences incumbent local inventors’ external collaborative innovation.

Demand Networks and Informal Volunteering
The British Journal of Sociology, EarlyView.ABSTRACT Patterns of volunteering have predominantly been explained by focusing on the supply side in terms of volunteers' resources and motivations. We shift the focus to the demand side of volunteering and develop the concept of demand networks.

Relative height and vertical status in buildings
Real Estate Economics, EarlyView.Abstract Motivated by research that associates higher positioning with well‐being, we expand the vertical price‐gradient literature by estimating the value of within‐ and between‐building “vertical status”: one's relative vertical position compared to others in the same building and in neighboring buildings, respectively. Employing an extensive dataset

SAMPLE SIZE DETERMINATION IN MIXED-EFFECTS ZERO INFLATED POISSON LONGITUDINAL DATA
, 2014 To determine sample size for a mixed-effects zero-inflated Poisson regression model via simulation. Zero inflated Poisson data was simulated first and then a mixed-effects ZIP regression model was fitted to evaluate the significance of the time trend ...
