Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Prisoners in their habitat? Generalist dispersal by habitat specialists: a case study in southern water vole (Arvicola sapidus). [PDF]

PLoS ONE, 2011
Habitat specialists inhabiting scarce and scattered habitat patches pose interesting questions related to dispersal such as how specialized terrestrial mammals do to colonize distant patches crossing hostile matrices.

Rapid generation of prion disease models using AAV‐delivered PrP variants in knockout mice

Brain Pathology, EarlyView.
We developed a rapid AAV‐based system to generate prion disease models in weeks rather than months. Following systemic AAV9P31 delivery of modified PrP to knockout mice, we achieved brain‐wide expression and successful propagation of both classical (RML) and atypical (GSS‐A117V) prion strains.

Influence of land mosaic composition and structure on patchy populations: the case of the water vole (Arvicola sapidus) in Mediterranean farmland. [PDF]

PLoS ONE, 2013
The ability of patchy populations to persist in human-dominated landscapes is often assessed using focal patch approaches, in which the local occurrence or abundance of a species is related to the properties of individual patches and the surrounding ...

Genomic variations define divergence of water/wildlife-associated Campylobacter jejuni niche specialists from common clonal complexes [PDF]

, 2011
Although the major food-borne pathogen Campylobacter jejuni has been isolated from diverse animal, human and environmental sources, our knowledge of genomic diversity in C.

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

Brain Pathology, EarlyView.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Revealing of Natural Leptospirosis Focus in Irkutsk Suburb

Эпидемиология и вакцинопрофилактика, 2015
For the first time natural leptospirosis focus was revealed in the Irkutsk suburb in 2012 - 2014 during epizootological inspection of a pond-marsh complex. Total 74 small animals (14 species) were examined, specific fragments of Leptospira DNA were found

Following the rivers: historical reconstruction of California voles Microtus californicus (Rodentia: Cricetidae) in the deserts of eastern California [PDF]

, 2016
The California vole, Microtus californicus, restricted to habitat patches where water is available nearly year-round, is a remnant of the mesic history of the southern Great Basin and Mojave deserts of eastern California.

Shedding light on the dark: Does artificial illumination affect mammal activity at waterholes in sub‐Saharan Africa?

Conservation Science and Practice, EarlyView.
We experimentally evaluated the effects of artificial lighting on mammal visitation patterns at waterholes in north‐central Namibia using motion‐activated camera traps across two dry seasons. Lighting had minimal effects on most species, although gemsboks increased use of artificially lit waterholes and lions reduced nocturnal activity at illuminated ...
