Patterns of biological diversity
2019Abstract This chapter examines how biodiversity, the variety of life, is distributed across the globe and within local communities. It begins by considering some of the challenges associated with assessing biological diversity at different spatial scales. Then, three of the best-studied patterns in species richness are examined in detail—

Summary1. Species diversity is most simply measured by counting species. More complicated measures, which take into account the relative abundance of the species, have been derived from information theory or from parameters of statistical distributions fitted to the census data.

Overview: Patterns in Diversity
2003The alpine landscape is, simplistically, characterised by its diversity of vegetation, landforms, parent rock types, soils, and water bodies. This diversity distinguishes it from the topographically far less varied, and hence less diverse, tundra region (Chapin and Korner 1995).

Ecology, 1992
In this paper I develop a new viewpoint with regard to species diversity by defining a new type, pattern diversity, to add to the previous categories of inventory and differentiation diversity. By defining and naming this entity, we expand our notions of the properties of ecological units, can integrate it with other ecological concepts, and ...

Mechanisms for diversity in gene expression patterns
Neuron, 1991Despite the relatively low number of transcriptional regulatory proteins, the number of possible combinations that act in particular cell types at specific times and in response to appropriate extracellular stimuli is enormous. In considering the regulatory patterns of a particular gene, the critical determinants of diversity are the specific promoter ...

The generation of diversity and pattern in animal development
Cell, 1992Experimental embryology started in the late 1800s asking such questions as whether one of the first two blastomeres of a 2-cell newt egg can compensate if the other is killed. Landmarks in the early history of developmental biology include cell culture (Harrison, 1910), the discovery of embryonic induction and the organizer (Spemann and Mangold, 1924),

Phanerozoic Diversity Patterns
1986Here twenty-one leading paleontologists use important refinements in fossil diversity data to provide critical evaluations of older hypotheses of diversification and extinction processes and to propose fresh interpretations. Originally published in 1986.

Speciation and Patterns of Diversity
2001Bringing together the viewpoints of leading ecologists concerned with the processes that generate patterns of diversity, and evolutionary biologists who focus on mechanisms of speciation, this book opens up discussion in order to broaden understanding of how speciation affects patterns of biological diversity, especially the uneven distribution of ...
