Species abundance distributions (SADs) follow one of ecology's oldest and most universal
laws–every community shows a hollow curve or hyperbolic shape on a histogram with many …

A building system is highly nonlinear and commonly includes a variety of parameters
ranging from the architectural design to the building mechanical and energy system. Serving …

Perhaps the lognormal distribution finds the widest variety of applications in ecology. Ever
since Malthus and Darwin, biologists have been acutely aware that populations of animals …

Quantifying the abundance of species is essential to ecology, evolution, and conservation.
The distribution of species abundances is fundamental to numerous longstanding questions …

This paper develops mathematical models to describe the growth, critical density, and
extinction probability in sparse populations experiencing Allee effects. An Allee effect (or …

Survival or extinction of an endangered species is inherently stochastic. We develop
statistical methods for estimating quantities related to growth rates and extinction …

2.1 Background Exhaustive empirical surveys have shown that, almost without exception,
macroparasites (parasitic helminths and arthropods) are aggregated across their host …

We consider the problem of inferring fold changes in gene expression from cDNA microarray
data. Standard procedures focus on the ratio of measured fluorescent intensities at each …

Allee effects are an important dynamic phenomenon believed to be manifested in several
population processes, notably extinction and invasion. Though widely cited in these …

We report on a new statistical test for detecting density dependence in univariate time series
observations of population abundances. The test is a likelihood ratio test based on a …
