Abstract Recently, conservation estate in South Africa's Eastern Cape Province has increased 10-fold resulting large predators being increasingly reintroduced to restore ecological integrity and maximize tourism. We describe the reintroductions of carnivores (>10 kg) that have occurred use various criteria assess their success. Lion Panthera leo reintroduction been highly successful with a population 56 currently extant region problems overpopulation arising. The African wild dog Lycaon...

Managers of African lions (Panthera leo) on reserves where they have been reintroduced increasingly face challenges associated with ecological regulation,genetic degradation and increased susceptibility to catastrophic events. The Lion Management Forum (LiMF) was formed in 2010 define these explore possible solutions the view developing appropriate management guidelines. LiMF bases its recommendations ecologically sound premise that managers should, as far possible, mimic natural processes...
Abstract Habitat selection and feeding ecology of a reintroduced population cheetahs Acinonyx jubatus were studied in 16 000 ha game reserve the Eastern Cape Province (South Africa). Seventy per cent is characterized by very dense thicket vegetation (valley bushveld) remainder open savanna‐like. The results illustrated strong effect sex group size on behaviour cheetahs. coalition (three adult males) killed significantly larger animals (55% kills weighed more than 65 kg) single female (less...
African rhinoceroses (rhinos) experienced a poaching onslaught since 2008 with the epicentre in South Africa where most of world’s rhinos occur. national parks, under management National Parks (SANParks), are custodian to 49% Africa’s white and 31% country’s black rhinos. We collated information on rhino population sizes seven parks from 2011 2015. include report surveys Kruger Park during 2014 Southwestern increased over study period, which allows SANParks achieve its contribution 2020...
To determine changes in the cervical screening service since introduction of new general practitioner contract on 1 April 1990.Analysis computerised records both before and after contract.General practices Perth Kinross Unit, Tayside.A total 30,071 women aged 21-60 26 partnership lists.Percentage average target population for each practice first three quarters contract.Perth Unit completed a call programme July 1989, which produced an increase from 71% to 78% mean percentage 20-60 who had...
For many years Tayside has benefited from a successful opportunistic cytology screening programme. In recent years, however, the decrease in mortality due to cervical cancer levelled off, with most cases of severe disease arising women who have not been screened. view this health board developed new computer system for call and recall based on community index. This facility allowed unscreened population be identified located an individual general practice basis. The findings programme 3136...
We collected data on the demography of cheetahs by direct observation over nine years Kwandwe Private Game Reserve and questionnaire seven fenced reserves in South Africa. Average age at independence was 17.5 months; females gave birth to their first litter cubs approximately 27.4 months average interbirth interval 17.8 months. The size emergence 4.2 there a significant difference between sizes with lions (2.9 cubs) compared those without (4.7 cubs). Age specific mortality higher four life...
Habitat loss, persecution and population declines have resulted in the restriction of many large carnivores, including cheetahs (Acinonyx jubatus), to fenced reserves. These reserves are often small likelihood interference competition between dominant subordinate predators is increased, while possibility spatial avoidance reduced. Given artificial space limitations, may reduce competitive interactions along niche axes other than habitat type such as time, coined a ‘management-induced shift’....
Abstract Human/carnivore conflicts are common across the globe, and with a growing human population, this conflict is likely to increase as space available large carnivores reduced. In South Africa, many small (< 400 km 2 ), fenced protected areas have reintroduced persecuted carnivores, such brown hyenas ( Hyaena brunnea ). These reserves great potential conserve hyena populations; consequently, understanding limitations that small, impose on use patterns needed. We investigated home...
Abstract Spatial patterns of and competition for resources by territorial carnivores are typically explained two hypotheses: 1) the defence hypothesis 2) searching efficiency hypothesis. According to hypothesis, when food abundant, carnivore densities will be high home ranges small. In addition, can maximise their necessary energy intake with minimal defence. At medium resource levels, larger needed, it become more economically beneficial defend against a lower density competitors. low...
Abstract African lions ( Panthera leo ) can influence the location, distribution and behaviour of smaller carnivores such as cheetahs Acinonyx jubatus ). In fenced protected areas, where space is limited, effects apex predator be exaggerated to point localized extinction subordinate. Here, we directly compare prey selection before after re‐introduction Mountain Zebra National Park, South Africa. The lion did not significantly diet cheetahs.

A protected area since 1999, Kwandwe Private Game Reserve incorporates several former farms, for which past records of bird occurrences are available. No species appear to have been lost from the area. Between 2001 and 2005, a group observers conducted systematic surveys in most months, allowed status (resident, migrant or irregular visitor) be determined. At least three established breeding populations reserve over 10 years. Of 302 reliably recorded date, 182 (60.3%) resident, 46 (15.2%)...
In this paper a computer system for cervical screening call and recall based on the Community Health Index (CHI) population data‐base is described. It allows unscreened to be identified located an individual general practice basis. The results of programme 9517 women aged 20–60 years listed CHI with no record smear There was 24% uptake in which meant that after total cover had risen from 71% 78%. addition, if valid reason are excluded, corrected longer area, true rises 88%.
