Spatial and temporal dynamics of an exploited reef-fish population
The successful management of the fishery for galjoen Dichistius capensis depends on an understanding of its spatial and temporal dynamics. This thesis investigates the movement of galjoen and its fishery parameters, and evaluates the role of marine protected areas (MPAs) and alternative assessment …

Exploiters and exploited: antagonism, mutualism and mimicry in an ecological community
… antagonistic systems, since exploiters and exploited parties exist from sub-cellular to super organismal levels. Second, I focus empirically on a pairwise interaction between a host and its parasite, while situating these interactions within their shared ecological community. My focal system …

Flood pulse influences on exploited fish populations of the Central Amazon
Seasonally fluctuating water levels, known as flood pulses, influence the population dynamics and catches of fishes from river-floodplains. Although different measures of flood pulses, here called flood pulse variables, have been correlated to changes in catches of river-floodplain fishes, the …

Reproductive biology and denning ecology of Virginia's exploited black bear population
During 1994-1996, reproductive biology and denning ecology of black bears (<i>Ursus americanus</i>) were investigated in the George Washington and Jefferson National Forests, Virginia. The average age of captured bears was 4.88 years (SE=0.43, n=64) and 2.72 years (SE=0.19, n=127) for females and …

Survival, Home Range and Spatial Relationships of Virginia's Exploited Black Bear Population
Eighty-three (21M, 62F) of 194 black bears captured during 1994-1996 were equipped with radio collars. Annual survival rates estimated with Kaplain-Meier staggered entry approach for radio collared adult females, adult males, subadult females, and subadult males were 95.3, 100.0, 90.4 and 50.0% …

Relationships between climate, growth and fisheries production in a commercially exploited marine fish
… these linkages are poorly understood for most exploited species, which hinders effective management. The purpose of this study was to use the Gulf Corvina (Cynoscion othonopterus), a heavily exploited marine fish in the Gulf of California, Mexico, as a model to investigate relationships between …

MODELLING CURRENT AND FUTURE WATER RESOURCES AVAILABILITY IN AN ALPINE CATCHMENT EXPLOITED FOR HYDROPOWER PRODUCTION
… model (ISAC-CNR) over the period 2016-2020 was exploited to test the predictivity of the hourly hydrologic model. The model was forced with weather forecasts (temperature and precipitation) for two months, namely the rainiest month (Oct 2018) and an average precipitation month (May 2018) in the …

A decision tree framework for assessing status of exploited marine ecosystems under changing environmental conditions
… decision tree framework to assess the status of exploited marine ecosystems, which could be successfully applied to numerous ecosystems and guide decision support under changing conditions. This work was based on that of the IndiSeas project, which makes use of indicators designed to detect the …

The CrISIS of Ludic Terrorism: Videogaming Exploited as a Means of Islamists’ Radicalization, Recruitment and Propaganda
… and exploiting gaming-adjacent platforms, is exploited at the service of Islamist terrorist and white supremacist causes. In this PhD dissertation, I examine the scope of ludic terrorism in the available gaming ecosystem, what has driven extremists to use these outlets, what gaming features …

An Examination of the Impacts of the Protection of Communities and Exploited Persons Act on Community-Based Organizations
… by passing The Protection of Communities and Exploited Persons Act (PCEPA). Little research exists that shows the impacts of the PCEPA on the Community-Based Organizations (CBO) who were actively involved with the consultation phases of both the Bedford ruling and the development of the PCEPA. …

Investigating the foraging ecology and energy requirements of a seabird population increasing in an intensely exploited marine environment
Their high energetic demands make seabirds sensitive to changes in prey availability, which is often reflected in their diet and energetic expenditure during breeding. Populations of the three seabirds endemic to southern Africa's Benguela upwelling ecosystem that rely on small pelagic fish have …

Aspects of the biology and population dynamics of the deep-water commercially exploited crabs off South West Africa/Namibia
Two crab species have been exploited on the South West African/ Namibian continental slope since 1973. The deep-sea red crab Geryon maritae forms >99 percent of the catch made by traps, the balance being a by-catch of stone crab Lithodes tropicalis. Historical information dating back to the late …

The Effects of Minimum Size Limit Regulations On Exploited Fish Populations off the Atlantic Coast of the Southeastern United States
… of the southeastern United States contains many exploited species that are managed with species-specific regulations, though primarily managed with minimum size limits. Minimum size limits vary by species and are intended to protect small fish in order to restrict harvest and prevent growth …

Biology, movement behaviour and spatial dynamics of an exploited population of smooth hound shark mustelus mustelus around a coastal marine protected area in South Africa
Aspects of the life-history, movement in relation to a Marine Protected Area (MPA) boundary, and short and long-term spatial behaviour in relation to environmental preferences of Mustelus mustelus were studied in the Saldanha Bay region on the west coast of South Africa. The overarching aim of this …

The effects of a marine reserve on galjoen (Dichistius capensis) at Cape Point, South Africa, and implications for the management of the recreational fishery
