This study documented the decline of the forests of the Petra Region of Jordan, as represented at Sidd al-Ahmar, within the Petra Archaeological Park. Biogeographical and anthropological methods were employed to explore the history of the forests. Archaeology and historical narratives provided a portrait of the study area from prehistory to the early 20th century. Aerial surveys from 1924 and 2002 were analyzed to quantify changes in forest cover. Mapping and inventory of indicator species measured short-term change between 2003 and 2006. Interviews, field observation and participant observation in the tourist industry provided a socio-cultural context for quantitative analysis and for recommendations for remediation of pressures on the remaining forest. The research documents a 58% decline in tree cover between 1924-2002, and a decline of 4.23% between 2003-2006. The conclusions question concepts such as "landscape integrity" and the usefulness of non-interventionist ideology in an historic and rapidly changing region.

On certain islands in the Seychelles archipelago a large and abundant animal is the Seychelles giant millipede, Seychelleptus seychellamm (Desjardins, 1834). This study quantifies the ecological role of this species in litter breakdown on Cousine Island, Seychelles. Observations on various ecological aspects and surface behaviour of this millipede were also made. The population of the Seychelles giant millipede on Cousine Island consists mostly of mature females, with few mature males and immatures. Apparent millipede density was higher at night (i.e. 4.44 ind.m⁻²) than during the day (i.e. 0.19 ind.m⁻²). Millipede biomass was 1.95 tons.ha¯¹. Millipedes were observed feeding on eight food types, with the most common food types being leaf litter and fallen fruit. Predation and scavenging on the Seychelles giant millipede was rarely seen, with only a total of 18 observations being made. The giant ghost crab was the only predator observed killing a millipede. The most common scavenger on dead millipedes was the Seychelles magpie robin. Mean litter ingested by the Seychelles giant millipede was 157 ± 28.1 mg.day¯¹ (n = 45) and mean faecal production was 111 ± 12.8 mg.day¯¹ (n = 45). On Cousine Island, the Seychelles giant millipede consumed daily, approximately 4.6 % of the total litter standing crop and approximately 17.2 % of the daily litter fall. Daily faecal production by the Seychelles giant millipede on Cousine Island was equivalent to approximately 2.9 % of the litter standing crop and to approximately 11.0 % of the daily litter fall. The implications of these results for nutrient dynamics and soil fertility on Cousine Island are discussed. Seven types of surface behaviour were observed being performed by the millipede. More behavioural types were observed at night than during the day, with burrowing and grooming being exclusively nocturnal behaviours. The most commonly observed behaviours were walking and feeding. Movement was more evident in the males and immatures, whilst feeding was more apparent in the females. Less behavioural types were observed in areas of low vegetational heterogeneity and complexity. Vegetation disturbance also had an inhibitory effect on millipede behaviour. Possible explanations for these differences in behaviour are discussed. The implications of these results for the conservation of the Seychelles giant millipede and Cousine Island are also discussed. / Thesis (M.Sc.)-University of Natal, Pietermaritzburg, 1999.

Kyrgyzstan is the single most seismically active country in the world. Accessing the past, and therefore future hazard of faults, necessitates a high-resolution understanding of the timing of different geologic events. With no radiometrically datable rocks from the Neogene of Kyrgyzstan, I herein present the first work formally describing Neogene vertebrate faunas from the Kochkor Basin of Kyrgyzstan. I utilize a combination of biostratigraphy and magnetostratigraphy to constrain the timing of when the vertebrate assemblages were emplaced, and have dated the three bone beds to all fall in the latest Miocene, spanning 9-5 million years ago. All four bone beds represent mass death assemblages, inferred to be from drought-caused mortality. The timing of the deposits corresponds to uplift in the Pamirs, Himalayan, and greater Tibetan Plateau, which would have blocked the Indian monsoon from reaching Central Asia, forever altering the climate and biota of the region. This change is reflected in the shifting mammals faunas, as evidenced by the novel rhinocerotid I describe in a phylogeographic context.
