Abstract 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.

Based on unedited bryophyte collections from the Arabian Peninsula and Socotra Island, six new records of mosses are reported for the area. New to the Arabian Peninsula are Pohlia elongata and Ptychostomum cernuum, the remaining four species are new records for Saudi Arabia, resp. Yemen (mainland) and the Socotra Archipelago. Most interesting is Hymenostylium hildebrandtii from the Makkah-Taif area, indicating the influence of the south-western monsoon rainfall far to the north. All taxa show major range extensions in Southwest Asia and contribute to the floristic diversity of the Arabian Peninsula.

Abstract The sand cat is one of the world’s least studied small cats. Our camera-trap survey, one of the largest undertaken in a desert system, generated over 1500 images of the species across 100 camera-traps distributed systematically over the 2400 km2 core area of the Uruq Bani Ma’arid Protected Area of the Empty Quarter, Saudi Arabia. The study revealed a much more significant and widespread sand cat population in the ecosystem than previously understood. Sand cats were detected across one-third of the core area in all major habitats, comprising escarpment plateau, sand dunes and interdunal gravel valleys. The species showed a marginal preference for the interior parallel dune system with interspersed gravel valleys where they also preferred sand dunes over the gravel valley in the hot season. There was no evidence of strong spatial interactions with other predators. The ecosystem’s larger predators (Arabian red fox and honey badger, and all records of wild and feral cats) were primarily associated with the escarpment plateau. The smaller Rueppell’s fox was the only other carnivore more consistently present in the main dune system. Sand cats were strictly nocturnal and 14% more active in the hot season than the cool season.
