Asynchrony of ageing among traits in a wild bird population Open
Ageing i.e. age-related changes in a trait, is a highly variable process. Studies have investigated variation in ageing among species and individuals, but little is yet understood about variation between traits. Evolutionary hypotheses arg…

Tusks, testosterone and personality in male Asian elephants ( <i>Elephas maximus</i> ) Open
Male Asian elephants exhibit phenotypic diversity in tusk development, with long, short and tuskless bulls varying in frequency among different populations. Although the factors that maintain tusk variation in Asian elephants remain unclea…

Long-term effects of early-life adversity on DNA methylation in zebra finches Open
Early-life experiences can have profound and long-lasting effects on adult phenotype and thereby Darwinian fitness, though the mechanisms driving these effects remain poorly understood. Epigenetic alterations, especially DNA methylation wh…

Socioeconomic Differences in Vaccination Coverage After a Mandatory Vaccination Law, 1855-1900 Open
Importance Mandatory vaccination is a major tool to combat increasing vaccine hesitancy. In principle, a vaccination law, ie, a mandatory vaccination law without exemptions, applies equally to everyone, but its effects across different soc…

Begging costs rather than food received cause brood size effect on growth in zebra finches Open
Altricial species rely on parental provisioning for early-life sustenance, and a larger brood size leads to higher levels of competition between siblings for parental resources. Early-life stress can have severe and lifelong effects on Dar…

Maternal pertussis immunization and the blunting of routine vaccine effectiveness: a meta-analysis and modeling study Open
A key goal of pertussis control is to protect infants too young to be vaccinated, the age group most vulnerable to this highly contagious respiratory infection. In the last decade, maternal immunization has been deployed in many countries,…

Testosterone variation in a semi-captive population of Asian elephants in Myanmar Open
Hormones are known to be involved in life-history trade-offs as systemic signals that establish functional links among traits and regulate key behavioural and physiological transitions between states in organisms. Although major functions …

Estimating the optimal age for infant measles vaccination Open
The persistence of measles in many regions demonstrates large immunity gaps, resulting from incomplete or ineffective immunization with measles-containing vaccines (MCVs). A key factor affecting MCV impact is age, with infants receiving do…

Grandmother presence improved grandchild survival against childhood infections but not vaccination coverage in historical Finns Open
Grandmother presence can improve the number and survival of their grandchildren, but what grandmothers protect against and how they achieve it remains poorly known. Before modern medical care, infections were leading causes of childhood mo…

The interactions of SARS-CoV-2 with cocirculating pathogens: Epidemiological implications and current knowledge gaps Open
Despite the availability of effective vaccines, the persistence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) suggests that cocirculation with other pathogens and resulting multiepidemics (of, for example, COVID-19 and in…

The epidemic dynamics of three childhood infections and the impact of first vaccination in 18<sup>th</sup>and 19<sup>th</sup>century Finland Open
Childhood infectious such as smallpox or measles have devasted human populations, but our knowledge on the history of public health interventions remains limited. Here, we use 100 years of newly available records in 18 th and 19 th century…

Glucose tolerance predicts survival in old zebra finches Open
The capacity to deal with external and internal challenges is thought to affect fitness, and the age-linked impairment of this capacity defines the ageing process. Using a recently developed intra-peritoneal glucose tolerance test (GTT), w…

The interactions of SARS-CoV-2 with co-circulating pathogens: Epidemiological implications and current knowledge gaps Open
Despite the availability of effective vaccines, the persistence of SARS-CoV-2 suggests that co-circulation with other pathogens and resulting multi-epidemics may become increasingly frequent. To better forecast and control the risk of such…

The Long-Term Success of Mandatory Vaccination Laws After Implementing the First Vaccination Campaign in 19th Century Rural Finland Open
In high-income countries, childhood infections are on the rise, a phenomenon attributed in part to persistent hesitancy toward vaccines. To combat vaccine hesitancy, several countries recently made vaccinating children mandatory, but the e…

Within‐individual repeatability in telomere length: A meta‐analysis in nonmammalian vertebrates Open
Telomere length is increasingly used as a biomarker of long‐term somatic state and future survival prospects. While most studies have overlooked this aspect, biological interpretations based on a given telomere length will benefit from con…

Town population size and structuring into villages and households drive infectious disease risks in pre-healthcare Finland Open
Social life is often considered to cost in terms of increased parasite or pathogen risk. However, evidence for this in the wild remains equivocal, possibly because populations and social groups are often structured, which affects the local…

Mosaic metabolic ageing: Basal and standard metabolic rates age in opposite directions and independent of environmental quality, sex and life span in a passerine Open
Crucial to our understanding of the ageing process is identifying how traits change with age, which variables alter their ageing process and how these traits associate with fitness. Here we investigated metabolic ageing in outdoor‐living c…
