Microsatellite analysis of seed dispersal and parentage of saplings in bur oak, Quercus macrocarpa
This study demonstrates the utility of microsatellite analysis for studying mating systems, seed dispersal and seedling establishment in natural plant populations.
Noninvasive paternity assignment in Gombe chimpanzees
While there is a positive relationship between male rank and reproductive success, it is demonstrated that a range of male mating strategies (possessiveness, opportunistic mating and consortships) can lead to paternity across all male ranks.

It is argued that population genetics theory may be misapplied in light of ecological realities that, when recognized, require scrutiny of underlying evolutionary assumptions.

The history and development of molecular parentage assignment in studies of native plants, as well as the limitations and constraints to this approach are reviewed, demonstrate that both seed and pollen dispersal are quite complex phenomena influenced by many ecological processes.
Characterization of highly variable (GA/CT)n microsatellites in the bur oak, Quercus macrocarpa
The results, indicating that (GA/CT)n microsatellites are both abundant and highly polymorphic in the bur oak genome, suggest that such genetic markers have tremendous potential for applications for studies of parentage, pollination and dispersal in temperate trees.

The role of coastal habitat preference and philopatry in shaping the distribution and population structure of lemon sharks is investigated and evidence of allopatric speciation corresponding to the Tethys Sea closure and isolation of the eastern Pacific N. brevirostris population is found.
Evolutionarily enlightened management
High levels of gene flow in bur oak revealed by paternity analysis using microsatellites
This study provides direct evidence for high levels of long-distance pollination in a wind-pollinated species, and contradicts traditional models of wind pollination which suggest that clouds of pollen dissipate from the source to ineffectively low densities over short distances.

The ubiquitous polyandry reported here raises the possibility that genetic incompatibility and post–copulatory paternity–biasing mechanisms may operate in viviparous sharks.
KINALYZER, a computer program for reconstructing sibling groups
A software suite KINALYZER reconstructs full‐sibling groups without parental information using data from codominant marker loci such as microsatellites based on combinatorial optimization and makes use of a Minimum 2‐Allele Set Cover approach based on Mendelian inheritance rules.
