Models for the logarithmic species abundance distributions

Theoretical Population Biology, 1974
Abstract Three models, developed by Karlin, McGregor and Ewens to describe evolving populations of selectively neutral genotypes, are shown to lead to various versions of Fisher's logarithmic series distribution for species abundance. Statistical inference procedures and measures of diversity which have been developed in one of the two contexts are ...

Species sensitivity distributions: data and model choice

Marine Pollution Bulletin, 2002
Species sensitivity distributions (SSDs) are increasingly incorporated into ecological risk assessment procedures. Although these new techniques offer a more transparent approach to risk assessment they demand more and superior quality data. Issues of data quantity and quality are especially important for marine datasets that tend to be smaller (and ...

Modelling Species’ Distributions

2011
Species distribution models have become a commonplace exercise over the last 10 years, however, analyses vary due to different traditions, aims of applications and statistical backgrounds. In this chapter, I lay out what I consider to be the most crucial steps in a species distribution analysis: data pre-processing and visualisation, dimensional ...

Building Statistical Models To Analyze Species Distributions

Ecological Applications, 2006
Abstract Models of the geographic distributions of species have wide application in ecology. But the nonspatial, single-level regression models that ecologists typically employ do not deal with problems of sampling irregularity or spatial dependence, and do not adequately quantify uncertainty. We show here how to build statistical models

Geostatistical Modeling of Species Distributions

1997
The geographic distribution of an organism forms a nested hierarchy of patterns across a range of spatial and temporal scales. Generalizing distribution patterns from locality data is difficult because of the inability to maintain a given level of sampling intensity with increasing spatial scale.

Virtual species distribution models

Progress in Physical Geography: Earth and Environment, 2014
Species distribution models (SDMs) have become a dominant paradigm for quantifying species-environment relationships, and both the models and their outcomes have seen widespread use in conservation studies, particularly in the context of climate change research.

Species Distribution Modeling in the Cloud

2012
Species distribution modeling is a process aiming at computationally predicting the distribution of species in geographic areas on the basis of environmental parameters including climate data. Such a quantitative approach has a lot of potentialities in many areas that include setting up conservation priorities, testing biogeographic hypotheses ...
