Sources, Sinks, and Population Regulation

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.
On the relationship between niche and distribution

Hutchinson’s niche concept can be modified to incorporate the influences of niche width, habitat availability and dispersal, as well as interspecific competition per se, and a simulation model called NICHE is introduced that embodies many of Hutchinson's original niche concepts and is used to predict patterns of species distribution.
Ecological Processes That Affect Populations in Complex Landscapes

We describe a general framework for understanding the ecological processes that operate at landscape scales. The composition of habitat types in a landscape and the physiognomic or spatial…
Optimal Foraging: A Selective Review of Theory and Tests

The general conclusion is that the simple models so far formulated are supported are supported reasonably well by available data and that the author is optimistic about the value both now and in the future of optimal foraging theory.
Sources, Sinks, and Habitat Selection: A Landscape Perspective on Population Dynamics
- H. Pulliam, B. Danielson
- Environmental ScienceAmerican Naturalist
- 1 June 1991
The model allows us to compare the relative contribution of different types of habitats to a species' growth rate and population size and predict how the loss of habitat of a particular type may affect a population.

Population Dynamics in Complex Landscapes: A Case Study.

A model designed to elucidate the effects of landscape-level variation in habitat dispersion on the size and extinction probability of avian populations in a region managed for timber production and results suggest that variation in demographic variables affects population size more than variation in dispersal ability.
The Sustainable Biosphere Initiative: An Ecological Research Agenda: A Report from the Ecological Society of America

In this document, the Ecological Society of America proposes the Sustainable Biosphere Initiative (SBI), an initiative that focuses on the necessary role of ecological science in the wise management…
On the Theory of Optimal Diets
- H. Pulliam
- Environmental ScienceAmerican Naturalist
- 1 January 1974
Using techniques of stochastic theory, a new aproach to predicting optimal diets is developed for a mobile predator feeding on stationary prey, predicting that an animal feeding according to the dictates of the optimal diet should show no partial preferences.
