Relations between forest and prairie fragmentation and depredation of artificial nests in Missouri
"Human settlement of native ecosystems has resulted in the destruction and fragmentation of habitats until, in many cases, only isolated remnants remain. The emerging field of conservation biology often examines these fragments, attempting to illucidate patterns of diversity, the mechanisms that …

… are a global problem, since continuous exposure of marine organisms to their low concentrations may result in bioaccumulation, and subsequent transfer to man through the food web (Mendil et al, 2005). Heavy metals in the marine environment may originate from either natural or anthropogenic …

Genetic variation in the European rabbit and rabbit flea in the British Isles
… Thirty-two loci were identified, five of which were polymorphic. Of these two (Sod-1 and Mpi-2) were widely polymorphic, the other three (Icd-2, Agp-1 and Mae-1) occurring at one site each. Genetic distances were consequently low, being no greater than 0.062 between any two individuals. …

The drivers of variation in susceptibility to the amphibian-killing fungus, batrachochytrium dendrobatidis
… (Bd) is regarded as a primary driver of the dramatic global declines experienced by amphibian populations in recent decades. The threat posed by Bd extends into pristine regions, decimating populations naïve to the pathogen. The patterns of genetic variation in amphibians in natural …

Architecting the deployment of cloud-hosted services for guaranteeing multitenancy isolation.
In recent years, software tools used for Global Software Development (GSD) processes (e.g., continuous integration, version control and bug tracking) are increasingly being deployed in the cloud to serve multiple users. Multitenancy is an important architectural property in cloud computing in which …

Biogeographical and ecological aspects of forest bird communities in eastern Tanzania.
My Ph.D. research is based on nearly three years of fieldwork in Tanzania, from December 1978 to September 1981. It attempts to deduce the effects of certain ecological and biogeographic-factors on the structure and species composition of forest bird communities. My principal study areas were in …

Ecology and physiology of a black bear (Ursus americanus) population in the Great Dismal Swamp and reproduction physiology in the captive female black bear
Ecology and physiology of black bears in Great Dismal Swamp (GDS) National Wildlife Refuge and surrounding area, a forested wetland in eastern Virginia and northeastern North Carolina, were studied from April 1984 to March 1987. A total of 101 bears (71M, 30F) were captured 120 times. Males …

Avian population responses to Anthropogenic landscape changes in Pohnpei, Federated Sates of Micronesia
… islands is also vulnerable to impending forces of global change. Scattered across the Pacific Ocean >20,000 islands range from sandspits to large islands and support some of the most unique biotic assemblages. Shaped by island size, topography and degree of isolation from other landmasses, …
