and Boundary Objects: Amateurs and Professionals in Berkeley's Museum of Vertebrate Zoology, 1907-39
Susan Leigh,James R. Griesemer +1 more
TL;DR: A model of how one group of actors managed this tension between divergent viewpoints was presented, drawing on the work of amateurs, professionals, administrators and others connected to the Museum of Vertebrate Zoology at the University of California, Berkeley, during its early years.

On territorial behavior and other factors influencing habitat distribution in birds
TL;DR: In this article, the Dickcissel sex ratio is employed as an indirect index of suitability and a sex ratio index was found to be correlated positively with density, consistent with the hypothesis that territorial behavior in males of this species limits their density.
Journal ArticleDOI
Genetics and demography in biological conservation
TL;DR: 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.
Journal ArticleDOI
Inverse density dependence and the Allee effect
TL;DR: The Allee effect describes a scenario in which populations at low numbers are affected by a positive relationship between population growth rate and density, which increases their likelihood of extinction.

Why Mountain Passes are Higher in the Tropics
TL;DR: In this article, it was suggested that the temperature gradient across a mountain range determines its effectiveness as a barrier, rather than the absolute height, and that animals and plants are evolutionarily adapted to, and/or have the ability to acclimate to, the temperatures normally encountered in their temporal and geographic habitat (or microhabitat).
