| description | Group size variations of the Arabian sand gazelle Gazella subgutturosa marica were studied during a period of drought at the Mahazat as-Sayd Protected Area in central western Saudi Arabia. Significant differences in median group sizes were observed between all seasons except summer. Single animals were observed mainly during summer while group sizes exceeding 10 individuals were observed mainly during winter. Solitary male and female groups were typically observed during winter and mixed groups mainly during the autumn rutting period. Most mixed groups were two to four times larger during winter than summer. The adult sex ratio (male: female) for all seasons combined was in parity and highest during autumn (1:1.23), probably as a result of prolonged drought conditions. The variability in group structure related to environmental conditions may be one factor permitting G. s. marica to adapt to hyper-arid habitats and climatic regimes in central western Saudi Arabia. The value of continuous monitoring of the gazelle population is emphasised for this drought prone region [Current Zoology 57 (1): 36–42, 2011]. |
