| Abstract | Abstract Aggregate estimates for wildlife populations and species diversity on private land in Namibia were made for 1972 and 1992, using questionnaire surveys. Numbers of species and biomass appear to have increased by some 80 percent, or three percent per annum over the period. The number of game species recorded increased by 44 percent. Cost – benefit analysis models were developed and used to analyse economic and financial efficiency of land use involving wildlife on private land. Financial profitability was generally low with both livestock – game production for consumptive use and wildlife production for non-consumptive use. However these activities appear to be economically efficient, and result in a positive contribution to National Income. The results suggest that there are financial incentives for private landholders to group together and form large scale conservancies. The latter benefit from economies of scale which make them more financially profitable and robust, and also more economically efficient, than ranches. Wildlife production for non-consumptive wildlife viewing was found to yield greater economic net value added per unit of land than livestock – wildlife production for consumptive use. This was particularly the case at the larger conservancy scale of operation. Aggregate estimates, in 1994 prices, of the annual net value added to National Income from wildlife use on private land are N$ 30.6 million in 1972 and N$ 56 million in 1992. The economic value of wildlife use as a proportion of the economic value of all private land rangeland uses appears to have risen from five percent to eleven percent over the twenty year period. Current policy to promote the development of wildlife conservancies appears to be economically sound, particularly where these are aimed at eventual conversion to wildlife-based tourism uses. _________________________ |

| Title | Expectations about numerical events in four lemur species (Eulemur fulvus, Eulemur mongoz, Lemur catta and Varecia rubra) | Type | Journal Article | ||

| Abstract | Although much is known about how some primates--in particular, monkeys and apes--represent and enumerate different numbers of objects, very little is known about the numerical abilities of prosimian primates. Here, we explore how four lemur species (Eulemur fulvus, E. mongoz, Lemur catta, and Varecia rubra) represent small numbers of objects. Specifically, we presented lemurs with three expectancy violation looking time experiments aimed at exploring their expectations about a simple 1+1 addition event. In these experiments, we presented subjects with displays in which two lemons were sequentially added behind an occluder and then measured subjects' duration of looking to expected and unexpected outcomes. In experiment 1, subjects looked reliably longer at an unexpected outcome of only one object than at an expected outcome of two objects. Similarly, subjects in experiment 2 looked reliably longer at an unexpected outcome of three objects than at an expected outcome of two objects. In experiment 3, subjects looked reliably longer at an unexpected outcome of one object twice the size of the original than at an expected outcome of two objects of the original size. These results suggest that some prosimian primates understand the outcome of simple arithmetic operations. These results are discussed in light of similar findings in human infants and other adult primates. | ||||

| Title | Injuries in the event horse: Training versus competition | Type | Journal Article | ||
| Year | 2008 | Publication | The Veterinary Journal | Abbreviated Journal | |
| Volume | 175 | Issue | 1 | Pages | 76-81 |

| Abstract | Two related studies on injuries sustained by event horses during competition and during training are reported. During the cross-country phase of competition, the most common injuries were lacerations and abrasions to the carpus and stifle. Superficial digital flexor tendonitis and exertional rhabdomyolysis were significantly more common during Cours Complete Internationale (CCI) competitions compared to one-day event (ODE) competitions. The difference in injury types at ODEs and CCI competitions probably relates to the increased athletic demands of the CCI and the closer veterinary observation at these competitions. The results of the training study indicate that 21% of horses intending to compete in a CCI did not start due to injury. Forty-three percent of these injuries involved soft tissue structures with injuries to the superficial digital flexor tendon and the suspensory ligament each accounting for 33%. The most important area for future research is investigation of the risk factors for these career-threatening soft tissue injuries. | ||||
