Winning by a neck – Sexual selection in the evolution of giraffe

A classic example of extreme morphological adaptation to the environment is the neck of the giraffe (Giraffa camelopardalis), a trait that most biologists since Darwin have attributed to competition with other mammalian browsers. However, in searching for present-day evidence for the maintenance of the long neck, we find that during the dry season (when feeding competition should be most intense) giraffe generally feed from low shrubs, not tall trees; females spend over 50% of their time feeding with their necks

Population statistics and carrying capacity of large ungulates in Whovi Wild Area, Rhodes Matopos National Park, Zimbabwe Rhodesia

Population data for introduced large ungulates, are presented to demonstrate population growth in terms of numbers and biomass in the Whovi Wild Area of the Rhodes Matopos National Park, Zimbabwe Rhodesia. Peak calving in relation to food requirements of different species is discussed. Standing crop of large ungulates was calculated and compared with carrying capacity as predicted by Coe et al. (1976)

Dentition and age determination of the giraffe Giraffa Camelopardalis

Thirteen tooth eruption stages and their corresponding chronological ages are described from a series of giraffe jaws. These can be used for age determination in giraffes with immature dentition. Significant correlations of the lingual crown height ( r=0.957; P<0.001) and lingual occlusal surface width (r=0.959; P<0.001) with the number of dark staining incremental lines in the cementum of thin decalcified sections of the maxillary first molar were found. The regression equations derived from these relationships provide a further method for
