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 ...

Ecology of greater sage-grouse populations inhabiting the northwestern Wyoming Basin

open access: yesHuman-Wildlife Interactions, 2017
Range-wide population declines of greater sage-grouse (Centrocercus urophasianus; sage-grouse) have been largely attributed to habitat loss and fragmentation. However, the specific conservation threats affecting the ecology of sage-grouse populations may

Critical Casimir Interactions and Percolation: the quantitative description of critical fluctuations

open access: yes, 2018
Casimir forces in a critical media are produced by spatial suppression of order parameter fluctuations. In this paper we address the question how fluctuations of a critical media relates the magnitude of critical Casimir interactions.

The performance of drones and artificial intelligence for monitoring sage‐grouse at leks

open access: yesWildlife Biology, EarlyView.
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

The importance of simulation assumptions when evaluating detectability in population models

open access: yesEcosphere, 2019
Population monitoring is important for investigating a variety of ecological questions, and N‐mixture models are increasingly used to model population size (N) and trends (λ) while estimating detectability (p) from repeated counts within primary periods (

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Adipokines in Obese Asthma: A Complex Relationship Influenced More by Sex, Weight, and Oral Steroid Treatment Than Disease Severity

open access: yesAllergy, EarlyView.
Adipokine secretion from adipose tissue may be involved in obesity‐related asthma, but it is unknown how adipokine levels relate to asthma characteristics. Plasma adipokines were measured in well‐characterized lean, overweight or obese patients with mild‐to‐moderate or severe asthma.

Location, orbit and energy of a meteoroid impacting the moon during the Lunar Eclipse of January 21, 2019

open access: yes, 2019
During lunar eclipse of January 21, 2019 a meteoroid impacted the Moon producing a visible light flash. The impact was witnessed by casual observers offering an opportunity to study the phenomenon from multiple geographical locations.

Sustained Clinical Improvement in Birch Pollen Allergy After Two Pre‐Seasonal Short Courses of Allergen‐Specific Immunotherapy: A Long‐Term Open‐Label Extension Study

open access: yesClinical &Experimental Allergy, EarlyView.
3 years follow‐up study to a DBPC dose‐finding trial investigating subcutaneous immunotherapy with T502 in birch‐pollen induced allergic rhinoconjunctivitis. 154 birch‐pollen allergic adults received short‐course treatment of 10,000 mTU/mL of T502 for 2 years and were observed during the next season without treatment.

Variable strength of forest stand attributes and weather conditions on the questing activity of Ixodes ricinus ticks over years in managed forests [PDF]

open access: yes, 2013
Given the ever-increasing human impact through land use and climate change on the environment, we crucially need to achieve a better understanding of those factors that influence the questing activity of ixodid ticks, a major disease-transmitting vector ...
