The desert bighorn sheep is adapted to the extreme conditions of arid ecosystems. The amount and distribution of watering holes is an essential component of the habitat of this species. With information provided by people in Sierra Santa Isabel a database of potential sites watering sites was obtained, which was taken as reference of spectral infor...

Introduction: Escape terrain and vegetation cover are two vital components in bighorn sheep habitat use. Understanding these components is essential for conserving and managing this species. Despite the importance of assessing habitat use, there are few studies in Mexico and most efforts have focused on population surveys. The lack of studies of bi...

INTRODUCCIÓN: El terreno de escape y la cobertura vegetal son dos componentes vitales en el hábitat del borrego cimarrón. La evaluación de la selección que hacen los borregos cimarrones de estos componentes es fundamental para determinar su distribución y el número de organismos que puede soportar un área. A pesar de la importancia de evaluar la se...

... From the ecology of populations and metapopulation theory (Hanski et al., 1994) to the ecology of movements and animal spatial distribution analyses, ecologists usually base their results on a planar measurement of the habitat area. Animal home range that is related to different habitat variables such as vegetation (Fernández et al., 2016;Ward et al., 2018), orientation (Singleton et al., 2010), altitude (Escobar-Flores et al., 2015) and slope (Lovari et al., 2017;Wangdi et al., 2019), is usually a planar measurement of the habitat area. In this regard, Heit et al. (2021) reviewed the literature on terrestrial animal home range estimation published between 2000 and 2019. ...
