Most epidemiological investigations of aetiology are observational. They look for associations between the occurrence of disease and exposure to known or suspected causes. In ecological studies the unit of observation is the population or community. Disease rates and exposures are measured in each of a series of populations and their relation is examined. Often the information about disease and exposure is abstracted from published statistics and therefore does not require expensive or time consuming data collection. The populations compared may be defined in various ways.
If you need to have a Wetland Review conducted on your property, a consultant first will need to make a site visit to gather field information about the topography, soils and vegetation. From this, a determination can be made as to whether or not any wetlands are present. If all three wetland characteristics are present in an area, the boundary of the wetland will need to be established and then marked or delineated with flagging or flagged stakes.
We study ecology, evolution and bio diversity of aquatic organisms, mostly fish, their prey and their predators. We are mostly concerned with evolutionary and ecological diversity dynamics. We wish to understand variation between evolutionary lineages in their rates and mechanisms of evolutionary diversification, in their current diversity, and in the rates of loss of diversity. This includes the origins, maintenance and loss of adaptive divergence between populations, of polymorphism's within populations, and of new species and macro evolutionary diversity.
Natural resource management is the taking care of natural resources such as land, water, marine and biological systems, with a particular focus on how the management affects the quality of life for both present and future generations. It’s about the long-term implications of actions - thinking about the future and not just about now. For primary producers, natural resource management means taking into account the climate, soils, water, vegetation and organisms when making decisions about the land they manage. The goal is sustainability - balancing social (people and communities), economic (money and jobs) and environmental (land, water, air and living things) factors to make sure that our children and grandchildren can equally benefit from our natural resources
