摘要: Abstract One of the consequences fragmentation is a combination increased proximity to human dominated areas and an influx free-roaming dogs. In fragmented habitats those dogs are expected have considerable impact on ungulate populations since conditions are, in effect, similar alien species islands. We studied ( Canis familiaris ) kid/mother ratio mountain gazelle Gazella gazella isolated area heavily disturbed by activity. used kid/female as index recruitment evaluated impacts dog presence, intensity disturbance, forage cover availability this over space time. Data were collected from direct observations. Overall, too low for population growth; finding that agreement with drive counts indicating consistent decline past four years (1998–2001). Our results show overwhelming factor affecting area. Gazelles responded positively quickly culling. Thus, appear be threat study Removal regular basis adequate short-term management protocol increasing rate. However, permanent solution would require reducing number limiting waste disposal. These suggest that, addition loss habitat connectivity, can major native ungulates landscapes.
