Sex, Age and Height Determination in Asiatic Elephant (Elephas Maximus): A Case Study
ثبت نشده
چکیده
The Asian or Asiatic elephant [1] is the only living species of the genus Elephas and is distributed in Southeast Asia from India in the west to Borneo in the east [2]. They are the largest living land animals in Asia and are primarily threatened by degradation, fragmentation loss of habitat and poaching [1]. Female captive elephants live beyond 60 years when kept in semi-natural surroundings, such as forest camps, but die at a much younger age and are declining due to a low birth and high death rate when kept in the zoos [3]. In general, the Asian elephant is smaller than the African elephant and has the highest body point on the head. The back is convex or level [4]. The ears are small with dorsal borders folded laterally. It has up to 20 pairs of ribs and 34 caudal vertebrae. The feet have more nail-like structures than those of African elephants, i.e. five on each forefoot and four on each hind foot. It becomes very difficult for a wild life expert or an Anatomist to differentiate the sex and to determine the age and height of an elephant when only the skeleton is available due to availability of scanty literature in this regard. So, the present investigation was carried out on the skeleton of the dead Asian elephant (Elephas maximus) to determine its sex, tentative age and height by investigating on the skeleton provided.

متن کاملBirth statistics for African (Loxodonta africana) and Asian (Elephas maximus) elephants in human care: history and implications for elephant welfare.
African (Loxodonta africana) and Asian elephants (Elephas maximus) have lived in the care of humans for many years, yet there is no consensus concerning some basic parameters describing their newborn calves. This study provides a broad empirical basis for generalizations about the birth heights, birth weights, birth times and gestation periods of elephant calves born in captivity. I obtained da...

Elephant-mediated transmission of tuberculosis is assumed to be similar to human models, which state close and prolonged contact with an infected individual is required for transmission. Although considered a risk factor for infection, several case studies have reported that close contact with an elephant is not always necessary for transmission, and the role of aerosolized bacteria remains unc...
متن کاملConstructing Age Structures of Asian Elephant Populations: A Comparison of Two Field Methods of Age Estimation
Construction of age structures of populations is central to studies of demography of large vertebrates (Caughley 1977). Unlike in the case of the African elephant (Loxodonta africana), there are few published age structures of wild Asian elephant (Elephas maximus) populations (Sukumar 1989, 2003). On the other hand, age/sex structures for several Asian elephant populations are available in repo...
