![]() Following each transect, through focal animal observations, we assessed and quantified stem diameters at point of browse (dpb, bite rates, and time budgets of mountain nyala in grasslands versus woodlands. We randomly laid out three transects in each habitat type. grasslands versus woodlands, and (2 quantify the bite rates (number of bites per minute and the activity time budgets of mountain nyala as functions of habitat type and sex-age category. The aims of this study were to: (1 measure and quantify habitat-specific stem bite diameters of mountain nyala foraging on common natural plant species in two major habitat types (i.e. Habitat use by mountain nyala Tragelaphus buxtoni determined using stem bite diameters at point of browse, bite rates, and time budgets in the Bale Mountains National Park, Ethiopiaįull Text Available We studied the habitat use of mountain nyala Tragelaphus buxtoni in the northern edge of the Bale Mountains National Park, Ethiopia.

Nyala and Bushbuck I: A Competing Species Model. ![]() There was no mortality or morbidity associated with this protocol. The anaesthesia was characterised by a short induction, good muscle relaxation and mild hypoxaemia during monitoring the anaesthesia was rapidly and completely reversed by naltrexone hydrochloride (30mg/mgof A3080 and atipamezole hydrochloride (5mg/mg of MED given intramuscularly. ![]() ![]() The optimum dosage for nyala was a combination of A3080 (40-50 mg/kg, MED (60-80 mg/kg plus 200 mg of KET/animal. The dosages developed on boma-habituated nyala proved to be equally effective in 9 adult free-ranging nyala (7 males and 2 females. Wide dosages were used safely during this study with ranges for A3080 of 45 + 8 mg/kg with MED of 69 + 19 mg/kg and KET of 3.7 + 1.0 mg/kg (200 mg/ animal. Anaesthesia of nyala (Tragelaphus angasi with a combination of thiafentanil (A3080, medetomidine and ketamineĭirectory of Open Access Journals (Sweden)įull Text Available A combination of thiafentanil (A3080, medetomidine hydrochloride (MED and ketamine hydrochloride (KET was evaluated in 19 boma-habituated (12 female and 7 males and 9 free-ranging nyala (7 male and 2 females (Tragelaphus angasi to develop a safe and reliable anaesthesia protocol. ![]()
