Crustacean hormone nuclear receptors: Characterization, gene expression, and evolution.
(1998)
Ecdysteroids are the arthropod molting hormones that control molting and limb regeneration in crustaceans. The actions of ecdysteroids are mediated through their nuclear receptor, ecdysteroid receptor (EcR). Studies in ...
A geography of extinction: Patterns in the contraction of geographic ranges.
(1998)
I examined the contraction of geographic ranges in 245 species. Remnant portions of the geographic range tended to persist in the periphery of the species' historical range. Larger patches of the geographic ranges persisted ...

(1998)
Forests in the Appalachian Mountains have been severely affected by logging in the past and little old-growth is left. The remaining forests form a heterogeneous mosaic of different forest successions. A concern for ...
A multiscale analysis of factors influencing the distributions of birds in the southern Great Plains.
(1998)
I studied the influence of local- and landscape-level habitat factors on breeding-bird communities in a prairie landscape in southwestern Oklahoma, U.S.A. Local habitat characteristics were sampled at study plot transects. ...
