An anthropological genetic perspective on creolization in the anglophone caribbean
This study highlights the complex socio‐cultural history of a broad region of the Caribbean and attests to the interplay between social and biological factors in shaping the genetic diversity present in present‐day communities.

Melanocortin‐1‐receptor (MC1R) variation is not associated with parasite burden in a neotropical bird, the bananaquit (Coereba flaveola)
It has been suggested that selection on melanocortin‐1‐receptor (MC1R) polymorphism, a common cause of melanic colour variation in vertebrates, results from pleiotropic effects of the gene in the immune system. Here we present the first test of whether MC1R variation is associated with differences in parasite abundance in a natural population. Bananaquits (Coereba flaveola) (Linnaeus, 1758) living on Grenada in the Caribbean exhibit a melanic plumage dimorphism as a result of a mutation in MC1R. The proportion of black individuals increases clinally towards the central, wetter parts of the island. We captured bananaqui...

The undocumented unwell.
Abstract
Nell Toussaint is not well. In recent years, she has been diagnosed with uterine fibroids, uncontrolled hypertension, nephrotic syndrome, poorly controlled diabetes, hyperlipidemia, and a pulmonary embolism. She also suffers from decreased mobility, shortness of breath, and-perhaps not surprisingly, given her other ailments-anxiety. Toussaint is an indigent undocumented immigrant living in Canada who has been trying to secure medical coverage in the federal courts. In the process, she has sacrificed the medical confidentiality that most of us ordinarily enjoy. Toussaint first came to Canada from G...
