Dispersal, recruitment and migratory behaviour in a hawksbill sea turtle aggregation
We investigated the dispersal, recruitment and migratory behaviour of the hawksbill sea turtle (Eretmochelys imbricata), among different life‐history stages and demographic segments of the largeExpand
What initiates speciation in passion-vine butterflies?
Studies of the continuum between geographic races and species provide the clearest insights into the causes of speciation. Here we report on mate choice and hybrid viability experiments in a pair ofExpand
Mimicry and warning colour at the boundary between races and species
Mimicry in butterflies is well known chiefly because it gives an easily understood visual example of adaptation. However, the major thrust of Bates's original paper "Contributions to an Insect FaunaExpand
Selection-driven evolution of emergent dengue virus.
In the last four decades the incidence of dengue fever has increased 30-fold worldwide, and over half the world's population is now threatened with infection from one or more of four co-circulatingExpand
Sex-specific migration patterns of hawksbill turtles breeding at Mona Island, Puerto Rico
Detailed post-breeding movement data is presented for hawksbill turtles tracked by satellite telemetry from Mona Island, Puerto Rico. Seven nesting females and 8 breeding males were tracked. FemalesExpand
Molecular evolution of dengue 2 virus in Puerto Rico: positive selection in the viral envelope accompanies clade reintroduction.
Dengue virus is a circumtropical, mosquito-borne flavivirus that infects 50-100 million people each year and is expanding in both range and prevalence. Of the four co-circulating viral serotypesExpand
Genetic mosaic in a marine species flock
We used molecular approaches to study the status of speciation in coral reef fishes known as hamlets (Serranidae: Hypoplectrus). Several hamlet morphospecies coexist on Caribbean reefs, and mateExpand
Genomic Hotspots for Adaptation: The Population Genetics of Müllerian Mimicry in the Heliconius melpomene Clade
Wing patterning in Heliconius butterflies is a longstanding example of both Müllerian mimicry and phenotypic radiation under strong natural selection. The loci controlling such patterns areExpand
Molecular evolution and phylogeny of dengue type 4 virus in the Caribbean.
We sequenced the E gene and adjacent prM/M and NS1 junctions (1940 bp) of 48 Dengue-4 (DEN-4) isolates collected between 1981 and 1999 from 8 Caribbean islands and from 7 South and Central AmericanExpand
Phylogeography and molecular evolution of dengue 2 in the Caribbean basin, 1981-2000.
We sequenced the envelope (E) genes of 59 DEN-2 isolates collected from ten Caribbean islands, six South American countries, and two Central American countries between 1981 and 2000, a periodExpand
