Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem. [PDF]

open access: yesMol Ecol
ABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

Avian Pox in Magellanic Penguins (Spheniscus magellanicus) [PDF]

open access: yesJournal of Wildlife Diseases, 2012
Avian pox is an enveloped double-stranded DNA virus that is mechanically transmitted via arthropod vectors or mucosal membrane contact with infectious particles or birds. Magellanic Penguins (Spheniscus magellanicus) from two colonies (Punta Tombo and Cabo Dos Bahías) in Argentina showed sporadic, nonepidemic signs of avian pox during five and two of ...

Contrasting patterns of selection between MHC I and II across populations of Humboldt and Magellanic penguins [PDF]

open access: yes, 2016
Indexación: Web of ScienceThe evolutionary and adaptive potential of populations or species facing an emerging infectious disease depends on their genetic diversity in genes, such as the major histocompatibility complex (MHC). In birds, MHC class I deals

Adaptive Genetic Variation in Black-and-White Snub-Nosed Monkeys (<i>Rhinopithecus bieti</i>): Low Diversity and the Role of Balancing Selection. [PDF]

open access: yesEcol Evol
We investigated the adaptive genetic diversity within a population of Rhinopithecus bieti using amplicon sequencing. From 47 individuals, we identified 16 MHC class I sequences, revealing a low level of adaptive genetic variation. Although evidence for balancing selection, including positive selection and trans‐species polymorphism, was observed, these

Up-beat motion in swimming limbs: New insights into assessing movement of free-living marine vertebrates. [PDF]

open access: yes, 2003
A new system is presented for assessing the movement of animal limbs including, after suitable calibration, quantification of limb stroke frequency and amplitude, which may be used to derive limb angular velocity and acceleration.

Population Trends of a Mixed-Species Colony of Humboldt and Magellanic Penguins in Southern Chile after Establishing a Protected Area [PDF]

open access: yes, 2013
Worldwide marine protected areas (MPAs) have been designated to protect marine resources, including top predators such as seabirds. There is no conclusive information on whether protected areas can improve population trends of seabirds when these are ...
