Abstract (sommario):

With a growing population in the world today, the pressure on land areas and wildlife is also increasing. In order to preserve certain land areas and endangered wildlife, so called community-based conservation programs are being created around the world. These programmes are aiming to benefit both local communities and wildlife in the same area. The difficult task is, however, to create incentive for poor communities to devotedly participate in these projects in order to prevent poaching, a common problem within conservation conflicts. It is important to consider all aspects regarding this iss

Abstract (sommario):

The conservation of wildlife is an important concern for many political actors. Wildlife is valued in a number of different ways and the development, priorities and outcomes of conservation policy can be better understood with recognition of these distinct ‘wildlife’ values held by the varied political actors involved in the policy process. This thesis describes these wildlife values and explores their impact on conservation policy through a comparison of six global conservation agreements; the International Convention for the Regulation of Whaling, Antarctic Treaty system, Ramsar wetlands con

Abstract (sommario):

Captive breeding plays an increasingly significant role in conservation programs, providing program managers with the challenge of preventing over-crowding, whilst also maintaining genetic and behavioural integrity of the population. This thesis assesses a new approach to the reproductive and genetic management of individuals in conservation programs by using contraception. Suprelorin contraceptive implants containing the GnRH agonist deslorelin were used to manage reproduction in two conservation-dependent species, the Tasmanian devil and burrowing bettong.

Abstract (sommario):

The success of state fish and wildlife agency conservation efforts depends highly on their engagement with wildlife recreationists, ranging from those with consumptive (i.e., hunters and anglers) to nonconsumptive (i.e., birders, wildlife viewers) interests. However, declines in their historic constituent base of consumptive recreationists, coupled with an increasingly diverse and interconnected group of nonconsumptive recreationists, has placed new pressures on state fish and wildlife agencies. Human dimensions research into recreationists' behaviors and perceptions can help these agencies de

<p> The extent of human disturbance is increasing, even in protected areas. I evaluated human disturbance impacts in Murchison Falls Conservation Area (MFCA), Uganda, a park in the Albertine Rift biodiversity hotspot, using two approaches.

I observed abrupt changes in productivity between the park and adjacent unprotected areas, indicating a "hard edge", and found evidence of edge effects that extended 4-6 km into MFCA.

My objectives were to (1) identify predators of white-tipped dove eggs and nestling, (2) determine how the predator community differs among land cover types, (3) examine the impact of vegetation and landscape variation in both citrus and woodland land cover types on nest survival, (4) examine the imp

In the last decade, the use of molecular markers revealing polymorphism at DNA level has played an increasing role in animal genetic and population studies.

Molecular markers are interesting and useful tools to assess genetic variability of species, breeds and populations, to infer population structure, to estimate genetic distances between breeds and individuals and also to define traceability methods for the identifica

Instead, Australian management models are grounded almost exclusively in the management of those species defined as pests.

Although the species is known to use a variety of upland and wetland habitat types, most previous research on the species has been conducted solely in uplands.

For instance, the average weight of a 20-year-old female declined from 55 kg in 1988 to 20 kg in 2014. The decline in size-at-age corresponds to a period of declining Pacific Halibut recruitment, spawning biomass, and reductions in catch limits for the directed commercial Pacific Halibut longline fishery. The causes of changes in Pacific Halibut size-at-age are poorly understood. Our project investigates several hypotheses related to declines in size-at-age, including the effects of

Abstract (sommario):

<p> Rails (Family: Rallidae) are among the least studied birds in North America, in large part due to their elusive nature. As a wetland-dependent species, understanding the timing of their migration and their habitat needs during migration is especially important since management needs to be timed to balance the needs of many species. I developed and verified a new distance sampling based nocturnal ATV spotlight survey because traditional call-broadcast surveys are not effective during autumn migration because of the drop off in call rate after the breeding season. These surveys allow us to a

Abstract (sommario):

<p> Sea-level rise is a concern for the future of coastal marsh obligate species such as the Clapper Rail (<i>Rallus crepitans</i>). Clapper Rails possess the potential to indicate changes to marsh ecological state due to population variation related to habitat features exhibited in previous study. Estimates for Clapper Rail survival are among the key missing parameters to create predictive models for Clapper Rail populations. I estimated Clapper Rail survival using data collected from six automated telemetry towers located in two Mississippi marshes. Thirty adult rails were harnessed with rad

Abstract (sommario):

<p> Historically, black bears occurred throughout Mississippi but by 1932, <12 bears remained. Repatriation in neighboring states and conservation efforts in Mississippi have led to the recolonization of at least 2 subspecies (<i>U. a. luteolus</i> and <i>U. a. americanus</i>) of black bears in the state. I compiled available data to provide a synthesis of the history, current status, and management of black bears in Mississippi. Additionally, I used global positioning data collected from radio collared bears to determine the influence of distance to source population, cover type, distance

Abstract (sommario):

<p>Tanzania has exceptional wildlife, environment and natural resources. The traditional way of conserving nature and wildlife has been through parks and reserves. In the 1980’s community based conservation emerged as a resource management paradigm. Its premise was that giving local people a stake in wildlife would increase their incentive to conserve it. This would make wildlife an important engine of local economic development. The core elements in community based conservation projects concern development, conservation and sustainable land use. Its ambition both to improve conditions for the
