Understanding the factors that determine the continued survival of small populations is a central problem in conservation biology. The Acorn Woodpecker (Melanerpes formicivorus) naturally occurs in small, isolated populations throughout much of the American Southwest. In spite of this distributional pattern, the species is neither rare nor endangered. Thus it appears to have successfully "solved" the problems to the problems of habitat fragmentation. We used data from a 10-yr field study and…

The Role of Immigration in the Decline of an Isolated Migratory Bird Population

Recruitment was unusually low in this population, suggesting the population's isolation on the periphery of the species' range has reduced the number of immigrants, and conventional management may not mitigate a population's decline if low immigration is responsible for the decline.

The demographic drivers of local population dynamics in two rare migratory birds

The finding that immigration plays a crucial role in the population growth rates of these two rare species emphasizes the need for a broad rather than local perspective for population studies, and the development of wide-scale conservation actions.

Ecological dynamics of extinct species in empty habitat networks. 1. The role of habitat pattern and quantity, stochasticity and dispersal

Contrary to most metapopulation model predictions, system persistence declined with increasing migration rate, suggesting that the mortality of migrating individuals in fragmented landscapes may pose significant risks to system-wide persistence.


A stage-based population model was used to explore the effects of habitat quality, connectivity, and catastrophes on long-term survival for four populations of Scrub Jays in Brevard County, Florida, United States.


The utility of an approach in which a single data set is "attacked" using a suite of models with different assumptions is demonstrated, showing evidence for density-dependent adult survival of the Acorn Woodpecker.

Habitat-specific demography of a long-distance, neotropical migrant bird, the eastern kingbird

I used data from a 10-yr study of Eastern Kingbirds (Tyrannus tyrannus) breeding in three habitats in the Charlotte Valley of central New York to describe population trends, and to examine how

Source‐Sink Dynamics of a Declining Eastern Kingbird Population and the Value of Sink Habitats

Abstract: I developed a demographic model for species inhabiting a mosaic of habitats of varying quality and among which dispersal was limited only by territorial behavior. I used the model to

Density-dependent immigration promotes population stability in a long-distance migratory bird

An integrated population model to study the extent and consequences of immigration on the dynamics of a neotropical migrant over an 11-year period in Ontario, Canada found no evidence for reduced breeding success and recommended the use of IPMs to address the spatial scale over which immigration occurs and how different scales influence its contribution to population dynamics.

Population extinction risks of three Neotropical small mammal species

Although the population growth of these three species can be approximated by purely stochastic processes, the introduction of density dependence through autoregressive log-linear models reduced the extinction times of all species analyzed.



Persistence of Different‐sized Populations: An Empirical Assessment of Rapid Extinctions in Bighorn Sheep

Data suggest that population size is a marker of persistence trajectories and indicate that local extinction cannot be overcome because 50 individuals, even in the short term, are not a minimum viable population size for bighorn sheep.

The Benefits-of-Philopatry Hypothesis for the Evolution of Cooperative Breeding: Variation in Territory Quality and Group Size Effects

A "benefits of philopatry" hypothesis is described, which proposes that nonbreeding helpers remain at home only when there is a net fitness benefit to doing so, and local patterns of variation in quality among individual territories may play an important role in the evolution of different social systems.

Territory Quality and Dispersal Options in the Acorn Woodpecker, and a Challenge to the Habitat-Saturation Model of Cooperative Breeding

It is suggested that competition for space may be the outcome of factors that promote philopatry, such as access to a critical resource and/or mutualistic benefits of living in a group and eventually breeding in the natal territory.

Genetics and demography in biological conservation.

The practical need in biological conservation for understanding the interaction of demographic and genetic factors in extinction may provide a focus for fundamental advances at the interface of ecology and evolution.

Viable Populations for Conservation: Minimum viable population size in the presence of catastrophes

Until a generalized theory covering both concepts is attempted, confusion may arise by the loose transfer of a numerical value of the MVP from the genetic to the demographic case, particularly the genetically derived values offered by Franklin (1980) and Soule (1980).

Minimum Population Sizes for Species Conservation

Many species cannot survive in mandominated habitats. Reserves of essentially undisturbed habitat are necessary if such species are to survive in the wild. Aside from increased efforts to accelerate
