The role of viability selection in shaping short- and long-term consequences of early-life conditions: An experiment in the Alpine swift
1 INTRODUCTION Stressful environmental conditions, such as food shortage, parasitism or competition, experienced early in life can have strong short-term effects on growth, morphology and survival (Boag, 1987; Dantzer et al., 2013; Fitze et al., 2004). Importantly, early-life conditions can also have lasting effects on the phenotype and life-history trajectories of individuals that survive to adulthood (Boag, 1987; De Kogel & Prijs, 1996; Fitze et al., 2004; Schluter & Gustafsson, 1993).
Variation in albumin glycation rates in birds suggests resistance to relative hyperglycaemia rather than conformity to the pace of life syndrome hypothesis
eLife Assessment This important study uses extensive comparative analysis to examine the relationship between plasma glucose levels, albumin glycation levels, and diet and life history, within the framework of the ‘pace of life syndrome’ hypothesis. The evidence that glucose is positively correlated with glycation levels and lifespan is convincing and, although there are some limitations related to data collection, they likely make the statistically significant findings more conservative.
Glycaemia and albumin glycation rates as fitness mediators in the wild: the case of a long-lived bird
Abstract Glucose is a vital metabolic component in the functioning of organisms, but it can also bind to biomolecules through non-enzymatic glycation reactions that result in loss of functions. While the effects of glycation on health have been well demonstrated in biomedical research, little is known about the effects of glycation in wild animals.
Trait‐specific sensitive developmental windows: Wing growth best integrates weather conditions encountered throughout the development of nestling Alpine swifts
1 INTRODUCTION In most animal species, adult size and mass are key life history traits, with larger and heavier individuals often having greater opportunities to monopolise resources (Basset & Angelis, 2007) and, in turn, greater survival and greater lifetime reproductive success (Baker et al., 2015; Brown et al., 1993; Speakman, 2005).

Importance of melanin‐based colouration and environment in shaping intracellular glutathione levels in nestling and adult tawny owls Strix aluco
Abstract Resources allocated in reproduction are traded off against those invested in self-maintenance such as antioxidant response. Glutathione (GSH) is an intracellular antioxidant defence that scavenges reactive oxygen species, the deleterious byproducts of oxygen consumption. Given the role of intracellular GSH in pheomelanogenesis, a trade-off in GSH allocation between resistance in oxidative stress and melanin production may take place.

Offspring telomere length in the long lived Alpine swift is negatively related to the age of their biological father and foster mother

Negative phenotypic and genetic correlation between natal dispersal propensity and nest-defence behaviour in a wild bird
Negative phenotypic and genetic correlation between natal dispersal propensity and nest-defence behaviour in a wild bird Pierre Bize, Grégory Daniel, Vincent A. Viblanc, Julien G. A. Martin, Blandine Doligez Biol. Lett. 2017 13 20170236; DOI: 10.1098/rsbl.2017.0236. Published 26 July 2017
Avian erythrocytes have functional mitochondria, opening novel perspectives for birds as animal models in the study of ageing
Altogether, those findings demonstrate that avian erythrocytes possess functional mitochondria in terms of respiratory activities and reactive oxygen species (ROS) production. Interestingly, since blood oxidative stress was lower for our avian model compared to a size-matched mammalian, our results also challenge the idea that mitochondrial ROS production could have been one actor leading to this loss during the course of evolution.
Can Stereotactic Body Radiotherapy Really Be Considered the Preferred Treatment in Large Hepatocellular Carcinoma?
The recent retrospective series by Wahl et al1 reported the results of 224 patients with inoperable nonmetastatic hepatocellular carcinoma (HCC) treated with radiofrequency ablation (RFA) or stereotactic body radiotherapy (SBRT). The authors acknowledged the unbalanced populations and used an inverse probability of treatment weighting in the Kaplan-Meier method and Cox models to account for the treatment-related bias.
