The Dynamics of Animal Distribution: An Evolutionary/ecological Model (Zoogeography, Biogeography)
Investigators have sometimes assumed that the factors underlying animal distribution are too complex to lend themselves to normative modelling. In this work, a model of environment and community interaction is constructed which lends itself to the latter kind of interpretation. It is posed that …

Geographic Variation in Dicamptodon Ensatus (Eschscholtz) with Notes on Life History and Zoogeography
The purpose of this paper is to present information concerning geographic variation between three northern populations of Dicamptodon, and to add to the meager store of information concerning the life history and biology of the species.

Taxonomy, phylogeny, and zoogeography of the weevil genus Euops (Insecta: Coleoptera: Curculionoidea) in the Papuan Region
The attelabid genus Euops SCHOENHERR is demonstrated to constitute a monophyletic group based on the following synapomorphies: 1) mycetangia of the female for storage of fungus spores consisting of three different reservoirs and associated setose structures, 2) a patch of modified setae of the …

The Effects of a Reservoir on Genetic Isolation in Two Species of Darters
The addition of dams into a riverine system causes a wide range of changes (i.e., sedimentation, erosion, thermal) to the river as well as to the fish assemblages of that river. Although there have been many studies documenting the changes that occur to the fish assemblages in the impounded river, …
