Female lineages anchored Pacific islands for 2000 years
Some 3000 years ago, people sailed toward the sunrise—and the last swatch of our planet uninhabited by humans: remote islands of the Pacific. By 1200 C.E.
societies flourished
from the Marianas to Rapa Nui, more than 12,000 kilometers apart. How the Pacific gradually became home to these groups—and just where they came from—has
long been a mystery
.
Some answers and twists are emerging, thanks to a large genomic study published today. Data from nearly 300 ancient and modern individuals reveals that at least five distinct groups migrated to the islands across 3 millennia. Once an island was i...

Implementation of an Adapted Collaborative Care Model
Psychiatr Serv. 2022 Apr 20:appips202100327. doi: 10.1176/appi.ps.202100327. Online ahead of print.ABSTRACTKosrae is an island state in the Federated States of Micronesia, a low- to middle-income country. Kosrae Community Health Center, an independent nonprofit organization, partnered with the Department of Psychiatry at the University of Hawai'i to integrate behavioral health services by using the collaborative care model (CoCM). The partnership encountered logistic and cultural challenges, but regular communication, case reviews, and training sessions enabled successful CoCM implementation. This success indicates that Co...

Post-Austronesian migrational wave of West Polynesians to Micronesia
This study examines Y-chromosome and mtDNA markers in the population of the island of Kiritimati in the context of geographically targeted reference populations from the Pacific. Kiritimati derives its population from the atoll islands of the Gilbert Archipelago and representsa geographicaltransitional region between Micronesia, Polynesia and Melanesia that likely played a critical role during theAustronesian expansion. The large presence(84.1%)of individuals withO-M175, O2a-M324 and O2a2b-P164 sub-haplogroups, 69.9% being O2a2b-P164, the Y-STR homogeneity within O2a2b-P164 and the very recent age of the sub-haplogroup(363...

Investigation of the Fungal Diversity of the Federated States of Micronesia and the Construction of an Updated Fungal Inventory
Mycobiology. 2021 Dec 24;49(6):551-558. doi: 10.1080/12298093.2021.2012327. eCollection 2021.ABSTRACTThe Federated States of Micronesia (FSM) is an island country in the western Pacific and is a known biodiversity hotspot. However, a relatively small number of fungi (236 species) have been reported till July 2021. Since fungi play major ecological roles in ecosystems, we investigated the fungal diversity of FSM from various sources over 2016 and 2017 and constructed a local fungal inventory, which also included the previously reported species. Fruiting bodies were collected from various host trees and fungal strains were i...
