A guide to estimating the age of Masai giraffes (Giraffa camelopardalis tippelskirchi)
This is a guide for estimating the age of Masai giraffes (Giraffa camelopardalis tippelskirchi) with noninvasive methods. Giraffes are commonly categorized into three age classes: calf (0 – 1 year), subadult (1 – 5 years) and adult (> 5 years). This categorization, though somewhat arbitrary, has its origins in giraffe life history. After birth, calves […]
Evolution of ruminant headgear: a review
The horns, ossicones and antlers of ruminants are familiar and diverse examples of cranial appendages. We collectively term ruminant cranial appendages ‘headgear’; this includes four extant forms: antlers (in cervids), horns (in bovids), pronghorns (in pronghorn antelope) and ossicones (in giraffids). Headgear evolution remains an open and intriguing question because phylogenies (molecular and morphological), adult […]
On elephants, giraffes, and social development
Social development rests on varied assumptions, including the greater effectiveness and efficiency of local over central management, legally endorsed resource control, and the popular ability to take responsibility for the environment. The article outlines the experience of community based natural resource management in Botswana in validating these and other assumptions, and concludes that in some […]
Serum gamma-glutamyltransferase as a prognostic indicator of neonatal viability in nondomestic ruminants
Rapid assessment of immune status in neonatal ruminants of endangered species facilitates early intervention in cases of inadequate passive transfer of maternal immunoglobulins. Serum gamma-glutamyltransferase (GGT) was used to evaluate suspected passive transfer status in 25 North Indian muntjac (Muntiacus muntjak vaginalis), 45 Cretan goats (Capra algagrus cretica), 20 white-lipped deer (Cervus albirostris), 25 Mhorr […]
