Approaches to the study of territory size and shape

Article Abstract:

Approaches to the study of territory size and shape are discussed to give an overview of theoretical studies of causes of intraspecific variation with focus on potential for predicting population-level phenomena. Classification of behavioral models of territory size and shape is undertaken. Three approaches, models of interactions among neighbors, focal resident models, and models of interactions between established residents and potential settlers, are considered. A large fraction of studies do not show an effect of food supply on territory size.

Analysis of selection on enzyme polymorphisms

Article Abstract:

Selection on enzyme polymorphisms has been studied. Amino acid polymorphisms may represent weakly deleterious mutations. Regulatory changes may be superimposed on structural changes, evidence indicates. Codon bias would imply that the functional differences seen in allozyme studies should be detectable by natural selection. Case studies mapping biochemical phenotype to higher phenotypes are discussed. Promising areas for better understanding selection on enzyme polymorphisms are discussed.
