Phylogeny and life histories of the 'insectivora': Controversies and consequences

Article Abstract:

The history of insectivore phylogenetics and systematics is reviewed, focusing on the relationships between the six extant families (Erinaceidae - hedgehogs and moonrats, Talpidae - moles and desmans, Soricidac - shres, Solenodontidae - solenodons, Tenrecidae - tenres and otter-shrews and Chrysochloridae - golden moles). It is examined how the various phylogenetic hypotheses influence the results of comparative analyses and the interpretation of insectivore life-history evolution.

Environments and evolution: Interactions between stress, resource inadequacy and energetic efficiency

Article Abstract:

The balance between energetic costs under variable environments and energy from resources provides a model for interpreting evolutionary stasis, punctuational and gradual change. The key to understand evolutionary change is ecological with focus on energy available in a stressed world.

Conceptual bases for quantifying the role of the environment on gene evolution: the participation of positive selection and neutral evolution

Article Abstract:

The article discusses the surveying and re-evaluating data in order to estimate the role of environmental changes on the course of species and genomic evolution.
