The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Current Zoology, 2013 Studies of metabolic variation in birds have involved both wild and captive individuals, but few studies have investigated whether captivity directly influences metabolic rates, despite such variation potentially confounding conclusions regarding how ...

Influence of body condition on influenza A virus infection in mallard ducks: experimental infection data. [PDF]
PLoS ONE, 2011 Migrating waterfowl are implicated in the global spread of influenza A viruses (IAVs), and mallards (Anas platyrhynchos) are considered a particularly important IAV reservoir.

Efectos de los atributos de la hembra de ñandú (Rhea americana) sobre la viabilidad del huevo [PDF]
, 2019 We conducted a study throughout a breeding season in a captive-bred population of Greater rheas (Rhea americana) to evaluate the association between egg viability and the female´s body weight and age.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Effects of age and captivity on plasma chemistry values of the Egyptian Vulture [PDF]
, 2012 Despite the interest in blood chemistry for studying ecological and pathological characteristics of birds, sources of variability such as age and captivity are poorly understood, and reference values usually are obtained from adult captive birds.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife
Biological Reviews, EarlyView.ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over
