TL;DR: Wildlife corridors are components of landscapes, which facilitate the movement of organisms and processes between intact habitat areas, and thus provide connectivity between the habitats within the landscapes as discussed by the authors, thus supporting continuance of land use for essential local and global economic activities in the region of reference.
Abstract: Wildlife corridors are components of landscapes, which facilitate the movement of organisms and processes between intact habitat areas, and thus provide connectivity between the habitats within the landscapes. Corridors are thus regions within a given landscape that connect fragmented habitat patches within the landscape. The major concern of designing corridors as a conservation strategy is primarily to counter, and to the extent possible, mitigate the effects of habitat fragmentation and loss on the biodiversity of the landscape, as well as support continuance of land use for essential local and global economic activities in the region of reference.

Abstract: Moving people for tigers: Resettlement, Food Security and Landscape-Level Conservation in Central India Amrita Neelakantan Resettlement of humans from protected areas conserves habitats for wildlife. However, impacts of resettlement on the well-being of resettled communities and on broader conservation goals at the landscape level have been poorly quantified until now due to inadequate documentation and baseline information. Recent documentation and advances in measurements of human well-being enable studies that examine the impacts of resettlement for both people and conservation. In India, the current standardized resettlement policy by the National Tiger Conservation Authority (NTCA) is explicit in its goal to create inviolate habitats for tigers within protected areas. More than 70% of the global tiger population lives in protected areas in India. The central Indian national parks hold approximately 40% of Indian tiger populations. Implementation of the NTCA policy provides an opportunity to study resettlement with relatively accurate records of where resettled households moved, a standardized monetary compensation and the potential for replication with large representative groups to study impacts in various landscapes across the country. This dissertation focuses on resettlement in Kanha National Park in central India, one of the most well-known and oldest tiger reserves in the country. The Kanha National Park (KNP) landscape mirrors the realities of many people-park interactions in human-dominated areas with high percentages of indigenous human populations, historical forced displacements, and current resettlements that follow a standardized national policy. From a conservation point of view, connectivity between KNP and other protected areas across central India is crucial for genetically healthy tiger populations. This dissertation consists of three analyses that combine data from field surveys and existing data sources to examine the impacts of resettlement on food security, landscape connectivity for wildlife, and human-wildlife conflict in the KNP landscape. In Chapter 1, I use household surveys to compare the food security and livelihood associations of resettled households compared to their non-resettled neighbors at new settlement locations. I show that resettled households have similar availability and access to foods as their non-resettled neighbors. Increases in off-farm income sources are associated with higher food access for all households. In Chapter 2, I explore the pattern of low food access in the KNP landscape using the five capitals model for sustainable development to illustrate significant associations between livelihood factors and household food access. Salaried stable incomes and kitchen garden diversity are significantly associated with higher food access. Financial capital dwarfs the contributions of social and natural capitals which have supplementary roles in times of financial stress. In Chapter 3, I address resettlement impacts on habitat connectivity between protected areas and human-wildlife conflict that resettled households face after relocating outside the park. Resettled households are not disproportionately moving into corridors between protected areas, especially when compared to the manifold more non-resettled households already residing in these areas. Resettled households however are moving into areas of high human-wildlife conflict due to their continued proximity to KNP. Outcomes from Chapter 3 also confirm that steady incomes can alleviate forest use and lower human activities in forests reducing human-wildlife conflict. In human-dominated landscapes such as KNP, financial capital and the stability of household incomes can aid both food security, lower pressures on non-protected forests and potentially lower human-wildlife conflict. The results counter assumptions that resettled communities continue to follow traditional natural resource reliant livelihoods. Local populations are not likely to engage in livelihoods that are heavily reliant on natural resources as rural populations become integrated into urban economies. The results from this dissertation imply that managers in the KNP landscape can alleviate food security and aid landscape wide conservation goals by increasing off-farm salaried incomes. Finally, in India, there is a high potential for replication of this study around other protected areas, with nationally standardized resettlement in landscapes that vary geographically, ecologically and socially.

01 Apr 1984TL;DR: In this paper, a model based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game was developed for cooperation in organisms, and the results of a computer tournament showed how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established.
Abstract: Cooperation in organisms, whether bacteria or primates, has been a difficulty for evolutionary theory since Darwin. On the assumption that interactions between pairs of individuals occur on a probabilistic basis, a model is developed based on the concept of an evolutionarily stable strategy in the context of the Prisoner's Dilemma game. Deductions from the model, and the results of a computer tournament show how cooperation based on reciprocity can get started in an asocial world, can thrive while interacting with a wide range of other strategies, and can resist invasion once fully established. Potential applications include specific aspects of territoriality, mating, and disease.

TL;DR: If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality, and the realized niche may be larger than the fundamental niche.
Abstract: Animal and plant populations often occupy a variety of local areas and may experience different local birth and death rates in different areas. When this occurs, reproductive surpluses from productive source habitats may maintain populations in sink habitats, where local reproductive success fails to keep pace with local mortality. For animals with active habitat selection, an equilibrium with both source and sink habitats occupied can be both ecologically and evolutionarily stable. If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality. In this sense, the realized niche may be larger than the fundamental niche. Consequently, the particular species assemblage occupying any local study site may consist of a mixture of source and sink populations and may be as much or more influenced by the type and proximity of other habitats a...
