The Anopheles dirus complex of mosquitoes contains some of the most important vectors of malaria in Southeast Asia. To distinguish five species of the complex that occur in Thailand, a method using the polymerase chain reaction (PCR) was developed. The method utilizes allele-specific amplification to detect fixed differences between the species in the DNA(More)
Separating the confounding effects of long-term population history from gene flow can be difficult. Here, we address the question of what inferences about gene flow can be made from mitochondrial sequence data in three closely related species of mosquitoes, Anopheles dirus species A, C, and D, from southeast Asia. A total of 84 sequences of 923 bp of the(More)
Knowledge of diet is critical in interpreting the ecological roles of marine top predators and provides information towards their conservation and management. The Falkland Islands hold the largest number of breeding gentoo penguins. Yet knowledge of gentoo penguin diet at the Falklands is limited to either broad taxonomic divisions of prey items or dietary(More)
Genetic structure and species relationships were studied in three closely related mosquito species, Anopheles dirus A, C and D in Thailand using 11 microsatellite loci and compared with previous mitochondrial DNA (mtDNA) data on the same populations. All three species were well differentiated from each other at the microsatellite loci. Given the almost(More)
An ongoing challenge in marine top predator research is understanding processes that are responsible for patterns that are often derived from land-based access to individuals. The use of animal-borne camera loggers, however, is proving useful in this regard as researchers can directly observe species and habitat-associated interactions. During an ongoing(More)
