Open AccessHow to solve novel problems: the role of associative learning in problem-solving performance in wild great tits Parus major
Although problem-solving tasks are frequently used to assess innovative ability, the extent to which problem-solving performance reflects variation in cognitive skills has been rarely formally investigated. Us...

Open AccessPost-mortem changes of the vascular system—a thanatological study using multidetector computed tomography
Forensic pathologists have to deal with post-mortem changes of the human body. Those post-mortem phenomena are familiar and largely described in thanatology. However, knowledge about the influence of post-mort...

Open AccessInter-individual variation in provisioning rate, prey size and number, and links to total prey biomass delivered to nestlings in the Collared Flycatcher (Ficedula albicollis)
In bird species where offspring growth and survival rely on parents’ food provisioning, parents can maximise their fitness by increasing the quantity and/or the quality of preys delivered to their offspring. M...

Open AccessTumor response and outcome after reverse treatment for patients with synchronous colorectal liver metastasis: a cohort study
The reverse treatment of patients with synchronous colorectal liver metastases (CRLM) is a sequential approach with systemic chemotherapy first, followed by liver resection, and finally, primary tumor resectio...

Open AccessEvidence of phenotypic correlation between exploration activity and resting metabolic rate among populations across an elevation gradient in a small rodent species
Behavior and metabolism are frontline reactions to environmental challenges that can covary in their response through at least two mechanisms. First, natural selection can generate correlation in phenotype amo...

Open AccessOxidative stress and mitochondrial responses to stress exposure suggest that king penguins are naturally equipped to resist stress
Exposure to unpredictable environmental stressors could influence animal health and fitness by inducing oxidative stress, potentially through downstream effects of glucocorticoid stress hormones (e.g. corticoster...

Open AccessDifferences in the oxidative balance of dispersing and non-dispersing individuals: an experimental approach in a passerine bird
Dispersal is often associated with a suite of phenotypic traits that might reduce dispersal costs, but can be energetically costly themselves outside dispersal. Hence, dispersing and philopatric individuals mi...

Open AccessPre-operative localization of solitary pulmonary nodules with computed tomography-guided hook wire: report of 181 patients
Video-assisted thoracic surgery (VATS) is currently performed to diagnose and treat solitary pulmonary nodules (SPN). However, the intra-operative identification of deep nodules can be challenging with VATS as...

Open AccessAvian erythrocytes have functional mitochondria, opening novel perspectives for birds as animal models in the study of ageing
In contrast to mammalian erythrocytes, which have lost their nucleus and mitochondria during maturation, the erythrocytes of almost all other vertebrate species are nucleated throughout their lifespan. Little ...

Open AccessConstraint and cost of oxidative stress on reproduction: correlative evidence in laboratory mice and review of the literature
One central concept in evolutionary ecology is that current and residual reproductive values are negatively linked by the so-called cost of reproduction. Previous studies examining the nature of this cost sugg...

Open AccessEffects of brood size manipulation and common origin on phenotype and telomere length in nestling collared flycatchers
Evidence is accumulating that telomere length is a good predictor of life expectancy, especially early in life, thus calling for determining the factors that affect telomere length at this stage. Here, we inve...
