Leapfrog migration and habitat preferences of a small oceanic seabird, Bulwer's petrel (Bulweria bulwerii) [PDF]

, 2015
Aim Our current understanding of migratory strategies and the reasons for their high variability along the phylogenetic tree remains relatively poor. Most of the hypotheses relating to migration have been formulated for terrestrial taxa; classically,

Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status

Global Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Evaluation of Panoramic Acquisition Errors by Predoctoral Dental Students

Journal of Dental Education, EarlyView.
Abstract Objectives Panoramic radiography is commonly used in the management of dental‐alveolar pathology. Novice clinicians are prone to technical errors that diminish the diagnostic quality of radiographs. The objective of this study was to analyze technical errors made during panoramic exposures by third‐year (D3) dental students in order to enhance

The Effect of Age on Survival Is Similar in Males and Females of an Aquatic Insect Species

Ecologies
Age is a critical intrinsic factor that influences the probability of survival of organisms on Earth. In many animals, the lifestyles and habitat occupancy of males and females are so different that the effect of age could be sex-dependent.

Ophidiomycosis Prevalence and Disease Ecology in a Natrix tessellata (Laurenti, 1768) Population From Northern Italy

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Fungal pathogens pose a growing threat to vertebrate biodiversity. In snakes, Ophidiomyces ophidiicola (Oo) has garnered particular concern, although its impact in Europe remains poorly understood. We conducted a season‐long, standardized survey of dice snakes (Natrix tessellata) along the northern shore of Lake Como (Italy) to quantify Oo and

Performance of a Deep Learning Algorithm for Melanoma Classification Across Diverse Dermoscopic and Tele‐Dermatology Datasets

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Early detection of melanoma significantly boosts patient survival rates. Deep learning has demonstrated dermatologist‐level accuracy in assessing pigmented skin lesions by analysing images at the pixel level. However, these neural networks may face challenges with ‘real‐life’ images due to limited training data and image artefacts ...

N-mixture models reliably estimate the abundance of small vertebrates

Scientific Reports, 2018
Accurate measures of species abundance are essential to identify conservation strategies. N-mixture models are increasingly used to estimate abundance on the basis of species counts.

High prevalence of trypanosomes in European badgers detected using ITS-PCR. [PDF]

, 2015
BACKGROUND: Wildlife can be important sources and reservoirs for pathogens. Trypanosome infections are common in many mammalian species, and are pathogenic in some.

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

Oikos, EarlyView.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

The strength of the association between heterozygosity and probability of interannual local recruitment increases with environmental harshness in blue tits [PDF]

, 2016
The extent of inbreeding depression and the magnitude of heterozygosity–fitness correlations (HFC) have been suggested to depend on the environmental context in which they are assayed, but little evidence is available for wild populations.
