Carrying capacity and demographic stochasticity: scaling behavior of the stochastic logistic model.
The stochastic logistic model is the simplest model that combines individual-level demography with density dependence. It explicitly or implicitly underlies many models of biodiversity of competing species, as well as non-spatial or metapopulation models of persistence of individual species. The model has also been used to study persistence in simple disease models. The stochastic logistic mode...
متن کاملIs dispersal always beneficial to carrying capacity? New insights from the multi-patch logistic equation.
The standard model for the dynamics of a fragmented density-dependent population is built from several local logistic models coupled by migrations. First introduced in the 1970s and used in innumerable articles, this standard model applied to a two-patch situation has never been completely analysed. Here, we complete this analysis and we delineate the conditions under which fragmentation associ...
متن کاملA Multidimensional Tourism Carrying Capacity Model: an Empirical Approach
It is often observed that tourism generates a negative impact on the environment of destination places, among which the depletion of the natural capital is the most evident. To avoid this, tourism development and management should be based on the recognition of the limits characterising a destination. The indicator of Tourism Carrying Capacity (TCC) can be particularly relevant to this purpose....
متن کاملAnalysis of an Economic Growth Model with Variable Carrying Capacity
In this paper, a kind of nonlinear delayed differential equations which can describe an economic model is considered. In this economy, population is modelled according to a logistically variable carrying capacity and capital’s accumulation has a time delay. By choosing time delay as a bifurcation parameter, it is proved that the system loses stability and a Hopf bifurcation occurs when the time...
متن کاملNovelties that change carrying capacity.
Comparative developmental studies have revealed a rich array of details about the patterns and processes of morphological change in animals and increasingly in plants. But, applying these insights to the study of major episodes of evolutionary innovation requires understanding how these novel morphologies become established and sufficiently abundant (either as individuals within a species or as...
