Movements and source–sink dynamics of a Masai giraffe metapopulation
Spatial variation in habitat quality and anthropogenic factors, as well as social structure, can lead to spatially structured populations of animals. Demographic approaches can be used to improve our understanding of the dynamics of spatially structured populations and help identify subpopulations critical for the long-term persistence of regional metapopulations. We provide a regional metapopulation analysis […]
Right on track? Performance of satellite telemetry in terrestrial wildlife research
Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite […]
Movements and group structure of giraffe (Giraffa camelopardalis) in Lake Manyara National Park, Tanzania
Movements and group structure of giraffe Giraffa camelopardalis were studied in Lake Manyara National Park, northern Tanzania. The giraffe population in Manyara had increased from 60 to 85 individuals between the early 1980s and 1991. This increase may have been the result of an increase in browse availability as a result of a dramatic decline […]
Home range and seasonal movements of Giraffa camelopardalis angolensis in the northern Namib Desert
Estimates of home range size of giraffe in the northern Namib Desert were on average larger than those in other populations. In particular, the largest individual home range of any giraffe bull (1950 km2) was recorded – correlated with low population density, reduced forage density and increased searching for receptive cows. The predominant pattern of […]
Home ranges, seasonal ranges and daily movements of giraffe (Giraffa camelopardalis giraffa) in northern Botswana
Introduction: Movement studies have been conducted on various giraffe subspecies across different ecological and management environments in Africa. However, prior to recent advancements in technology, studies were limited to identification methods relying on chance encounters of individuals (e.g. Foster, 1966; Berry, 1978; le Pendu & Ciofolo, 1999) and VHF radio-tracking (e.g. Langman, 1973; Dagg & […]
