NATURAL SELECTION AND RANDOM GENETIC DRIFT IN PHENOTYPIC EVOLUTION
  • R. Lande
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 June 1976
In discussions of the major features of evolution, Simpson (1953) applied population genetic models to the interpretation of the fossil record. Most population genetics theory concentrates on detailsExpand

Assessing Extinction Threats: Toward a Reevaluation of IUCN Threatened Species Categories
IUCN categories of threat (Endangered Vulnera- ble, Rare, Indeterminate, and others) are widely used in 'Red lists' of endangered species and have become an important tool in conservation action atExpand

Extinction Thresholds in Demographic Models of Territorial Populations
  • R. Lande
  • Biology
  • The American Naturalist
  • 1 October 1987
A basic demographic model is constructed for territorial species in a region where patches of habitat suitable for survival and reproduction are randomly (or evenly) interspersed with patches ofExpand

Mutation and Conservation
Mutation can critically affect the viability of small populations by causing inbreeding depression, by maintaining potentially adaptive genetic variation in quantitative characters, and through theExpand

EVOLUTIONARY MECHANISMS OF LIMB LOSS IN TETRAPODS
  • R. Lande
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 March 1978
Loss of limbs is one of the most extreme morphological changes in the history of tetrapods, yet it has evolved repeatedly in amphibians, reptiles, birds, and mammals. For none of these groups isExpand

A Population Viability Analysis for African Elephant (Loxodonta africana): How Big Should Reserves Be?
We present an age-structured, density-dependent model of elephant population dynamics in a fluctuating environment, drawing primarily upon the life history parameters obtained from studies inExpand

STATISTICAL TESTS FOR NATURAL SELECTION ON QUANTITATIVE CHARACTERS
  • R. Lande
  • Biology, Medicine
  • Evolution; international journal of organic…
  • 1 June 1977
Evolutionary biologists tend to ascribe phenotypic changes in populations to natural selection. Plausible hypotheses are regularly offered to explain how certain features of an organism are adaptiveExpand

Mechanisms of rapid sympatric speciation by sex reversal and sexual selection in cichlid fish
Mechanisms of speciation in cichlid fish were investigated by analyzing population genetic models of sexual selection on sex-determining genes associated with color polymorphisms. The models areExpand

Molecular genetic and behavioral analysis of social organization in the Asian elephant (Elephas maximus)
Abstract We report on the genetic evaluation and behavioral study of social organization in the Asian elephant (Elephas maximus). Although Asian elephants and African elephants (Loxodonta africana)Expand

DEPRESSION IN PLANTS. I. GENETIC MODELS
Summary. -The amounts of inbreeding depression upon selfing and of heterosis upon outcrossing determine the strength of selection on the selfing rate in a population when this evolves polygenicallyExpand
