The parkland is a mix of meadows and forests between the elevations of 5,000 and 7,000 feet. Tree cover in the parkland is controlled by the depth and timing of snow cover. The sub-alpine parkland is some of the most visited, cherished and photographed areas of Mount Rainier National Park.. A study in new methodology that enables continuous time statistical inference.. The Hudson Bay hare/lynx catchment data. 100 years of catchment data for the Hudson Bay company. . The lynx data has some holes.. .. There are a lot of factors that affect the populations within a biological . community.. Some . have to do with organisms themselves.. Others relate to the habitat. . Any factor or conditio. n that limits the growth of a population in an ecosystem is called a limiting factor.. Desired results. Here’s an approximation of reality:. The hare birth rate is constant, as their food supply is unlimited. Hares only die when eaten by a lynx, and the number of hares eaten is proportional to how often hares & lynxes meet, i.e., the chance of a lynx catching a hare.. the. Białowieża . Forest. Bark .
