Maintaining the Population of Thornicroft Giraffes (Giraffa camelopardalis thornicrofti)

There is a lack of information on the Thornicroft giraffe’s population size and of the amount of poaching taking place on the giraffes with in the Southern Luangwa Valley National Park. As of right now the giraffes population appears to be stable but there are a lot of factor unknown pertaining to the threats to the population and to their habitat. The goal of this management plan is to maintain the Thornicroft Giraffes population which is exclusively found in Luangwa

Applying computer-aided photo-identification to messy datasets: a case study of Thornicroft’s giraffe (Giraffa camelopardalis thornicrofti)

Digital photography enables researchers to rapidly compile large quantities of data from individually identifiable animals, and computer software improves the management of such large datasets while aiding the identification process. Wild-ID software has performed well with uniform datasets controlling for angle and portion of the animal photographed; however, few datasets are collected under such controlled conditions. We examined the effectiveness of Wild-ID in identifying individual Thornicroft’s giraffe from a dataset of photographs (n = 552) collected opportunistically in the Luangwa

Population census of Thornicroft’s giraffe Giraffa camelopardalis thornicrofti in Zambia, 1973−2003: conservation reassessment required

Thornicroft’s giraffe Giraffa camelopardalis thornicrofti is limited in distribution to a single population resident in the Luangwa Valley, Zambia. During 1973 – 2003 regular counts were recorded along the Luangwa River in the core section of the subspecies’ range. In 2013 we conducted a count in the same region for comparison with the earlier survey results. During the 30-year period 1973 – 2003 the giraffe index (no. of individuals per km surveyed) was relatively stable, with an increase in 1994

Reproductive failure in female Thornicroft’s giraffe (Giraffa camelopardalis thornicrofti) in Zambia

Reproductive suppression is common among mammals residing in cooperative social systems and is characterized by the cessation of ovulation in subordinate females until their social environment releases them from a temporary freeze on ovulating (e.g., dwarf mongoose, Helogale parvula (Creel, Creel, Wildt, & Monfort, 1992); African wild dogs, Lycaon pictus (Creel, Creel, Mills, & Monfort, 1997); wolves, Canus lupus (Packard, Seal, Mech, & Plotka, 1985); Damaraland mole rats, Cryptomys damarensis (Bennett, 1994); common marmosets, Callthrix jacchus (Barrett, Abbott, & George,

Ecological determinants of herd size in the Thornicroft’s giraffe of Zambia

Ecological factors have a pervasive impact on animal population sizes and the structure of their social systems. In a number of ungulate species, predator pressure exerts a major influence on group size. Given that giraffe (Giraffa camelopardalis) live in an extremely flexible social system, and that breeding is non-seasonal, they are an ideal species for examining how ecological variables contribute to fluctuations in herd size. We present an analysis of 34 years of data on a population of Thornicroft’s giraffe

Mitochondrial DNA analyses show that Zambia’s South Luangwa Valley giraffe (Giraffa camelopardalis thornicrofti) are genetically isolated

Thornicroft’s giraffe, Giraffa camelopardalis thornicrofti, is a geographically isolated subspecies of giraffe found only in north-east Zambia. The population only occurs in Zambia’s South Luangwa Valley,  an area which interestingly places it between the current distribution of Masai (G. c. tippelskirchi) giraffe to the north, and the Angolan (G. c. angolensis) and South African (G. c. giraffa) giraffe in the south-west and south, respectively. Specific studies have been undertaken on the ecology of this subspecies, but their population genetics remains

Leadership of herd progressions in the Thornicroft’s giraffe of Zambia

In cohesive social groups, travel progressions are often led by dominant or older individuals, but the leadership traits of individuals residing in flexible social systems are poorly known. Giraffe reside in herds characterized by fission– fusion dynamics frequently mediated by kinship. We analyzed 41 years (1971–2012) of longitudinal data collected from a community of Thornicroft’s giraffe (Giraffa camelopardalis thornicrofti) living around South Luangwa National Park, Zambia, to assess the characteristics of herd leaders. Movement of giraffe in a single file
