“…elevational migration, nomadic or erratic movements), which are related to the very unpredictable seasonality of alpine environments (e.g. climate conditions and resource availability; Borras et al 2010, Henry 2011, Boyle 2018, Novoa et al 2020, Resano‐Mayor et al 2020, Barras et al 2021). Even for species thought to be largely resident or to move over short distances, there is some evidence of relatively long movements of individuals during the non‐breeding season (Resano‐Mayor et al 2020), which might increase the chances of finding some transient individuals outside what could be regarded as the species' niche.…”

“…Las hembras jóvenes realizan desplazamientos dispersivos pudiendo establecer el lugar de nidificación a 18 km del lugar de su nacimiento (Ellison, 2018). En relación al efecto de las barreras geográficas en la dispersión, la especie en los Pirineos raramente cruza valles de 10-12 km de ancho en vuelo directo (Novoa et al, 2021). El éxito reproductor ha disminuido en los últimos años de 1,3 pollos/adulto a 0,3 pollos/adulto Gil et al, 2004a).…”

Se revisa, actualiza y obtiene información sobre el lagópodo alpino (Lagopus muta) en el Pirineo Central (Aragón-España). Se obtienen 303 observaciones (enero-diciembre 2000-2020), situándose la mayor parte de las observaciones entre 2.500 y 2.700 m.s.n.m. La especie está presente en 38 cuadrículas UTM de 10 x 10 km. Su hábitat potencial es de 832 km2 y su área de ocupación de 607,4 km2. El 82% del área de ocupación se localiza en Red Natura 2000. La superficie de ocupación en época reproductora (abril-octubre) es de 253,5 km2. Se estima una población de 1142 ±105 parejas. Especie catalogada como “Vulnerable” en Aragón, se desconoce su tendencia poblacional. Debido a los impactos causados por el cambio climático, los modelos predictivos establecen escenarios de contracciones en su distribución y disminución de sus efectivos poblacionales. Con la información obtenida se pueden establecer y mejorar las medidas de protección de la especie y su hábitat en los Planes de Conservación y Gestión de Aragón.

Dispersal is an important life history trait that plays a crucial role in avoiding inbreeding. Uncovering the dispersal pattern of a threatened species facilitates conservation efforts. Most species of Galliformes are forest-dwelling terrestrial birds with a weak dispersal ability and high conservation priorities. However, little is known about the dispersal behavior and dispersal pattern of Galliformes species such as Reeves’s pheasant Syrmaticus reevesii, a globally vulnerable species endemic to China. Here, we integrated behavioral and genetic analyses to investigate the dispersal pattern of Reeves’s pheasant. Our results revealed that both females and males would disperse, although the overall dispersal pattern was more likely to be male-biased. Reeves’s pheasant population had a low level of genetic diversity, and a mild level of inbreeding. With speculating low genetic diversity was resulted by fragmented habitat, and male-biased dispersal may reduce the opportunity of inbreeding. Our research indicated that sex-biased dispersal patterns may be a behavioral mechanism adopted by wildlife to avoid inbreeding in a fragmented habitat.
