Sex determination and population biology in the hymenoptera.
Genetic Intrigues. (Book Reviews: Evolution of Social Insect Colonies. Sex Allocation and Kin Selection.)
This work focuses on the evolution of colony characteristics in insects and investigates intra-colony conflicts over sex allocation in the context of inclusive fitness and sex allocation.
Integrative taxonomy: a multisource approach to exploring biodiversity.

A flexible procedure and stopping rule is presented that uses the information from different disciplines separately for integrative taxonomy, finding that rigor in species delimitation can be increased when several disciplines chosen for complementarity are used.
Polyandry in social Hymenoptera — disunity in diversity?
Comparative analysis reveals a negative correlation between level of genetic diversity and parasite load and findings in the best-studied case are complex: monandry and higher levels of polyandry are each selectively favored over moderatepolyandry.
The relationship between population genetic structure and pelagic larval duration in coral reef fishes on the Great Barrier Reef
These genetic patterns are consistent with moderate gene flow among well-connected locations and indicate that at this phylogenetic level (i.e., within family) the duration of the pelagic larval phase is unrelated to the patterns of genetic differentiation.
Modes of spontaneous chromosomal mutation and karyotype evolution in ants with reference to the minimum interaction hypothesis.
Translocations and Robertsonian polymorphisms are confirmed to be non-randomly distributed among ants, consistent with the minimum interaction hypothesis of Imai et al. (1986), under which translocations are expected to occur most frequently in low-numbered karyotypes.
Preserving the Information Content of Species: Genetic Diversity, Phylogeny, and Conservation Worth

Gene number is an important component of assessing conservation value, and Phylogenetic measures are better indicators of conservation worth than species richness, and measures using branch-lengths are better than procedures relying solely on topology.
The cytochrome b region in the mitochondrial DNA of the ant Tetraponera rufoniger: Sequence divergence in hymenoptera may be associated with nucleotide content
The high A + T%, the biased codon usage, and the increased PPC divergence of Hymenoptera can in that respect most easily be explained by directional mutation pressure which began in the Upper Carboniferous and still occurs in most members of the order.
Phylogenetic evidence for a single, ancestral origin of a ‘true’ worker caste in termites
A test for correlated evolution which takes phylogenetic structure into account indicates that this pattern is of biological significance and suggests that the variable occurrence of a worker caste in termites has ecological determinants, apparently linked to differences in feeding and nesting habits.
