Miniaturization of Body Size: Organismal Consequences and Evolutionary Significance
Evaluation of causes and consequences of miniaturization should consider obvious feattires of physical size as well as less obvious, but biologically important, features such as genome and cell size.
Developmental basis of evolutionary digit loss in the Australian lizard Hemiergis.
A comparative analysis of expression of MSX and Distal-less proteins among embryos from different populations suggests an early role for SHH in specification of digit identity and later importance in maintaining cell proliferation and survival in Hemiergis.

Multiple paternity in Belding's ground squirrel litters.
The paternity of 27 litters born in 1977 and 1978 was ascertained by combining field observations of mating with laboratory paternity exclusion analyses, and it may be the highest frequency of multiple paternity ever directly demonstrated in a natural population.
Skeletal development in Xenopus laevis (Anura: Pipidae)
An assessment of variation of skeletogenesis within a single population of larvae and comparison with earlier studies revealed that the timing, but not the sequence, of skeletal development in X. laevis is more variable than previously reported and poorly correlated with the development of external morphology.
There is no highly conserved embryonic stage in the vertebrates: implications for current theories of evolution and development
It is found that embryos at the tailbud stage – thought to correspond to a conserved stage – show variations in form due to allometry, heterochrony, and differences in body plan and somite number, which foreshadow important differences in adult body form.
Mapping the biosphere: exploring species to understand the origin, organization and sustainability of biodiversity
It is concluded that an ambitious goal to describe 10 million species in less than 50 years is attainable based on the strength of 250 years of progress, worldwide collections, existing experts, technological innovation and collaborative teamwork.
Miniaturization and its effects on cranial morphology in plethodontid salamanders, genus Thorius (Amphibia, Plethodontidae): II. The fate of the brain and sense organs and their role in skull

Changes in gross morphology of the brain and sense organs that have accompanied the evolution of decreased head size in Thorius are identified and their relation to associated changes in skull morphology is identified.
Patterns of structural and systematic diversity
In this authoritative three-volume reference work, leading researchers bring together current work to provide a comprehensive analysis of the comparative morphology, development, evolution, and
