This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific.
The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR.
SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).

Forget A Better Mousetrap: Save The Forest
From : Science Daily
ScienceDaily (Apr. 13, 2006) — The most cost-effective way to stop non-native rats and mongoose from decimating highly endangered species on larger tropical islands is not by intensive trapping, but instead by preserving the forest blocks where wildlife live, according to a study by the Bronx Zoo-based Wildlife Conservation Society (WCS) and other groups.
The study, which appears in the latest issue of the journal Conservation Biology, found that rats and mongoose in the Fiji Islands rarely penetrate the forest interior, preferring instead to forage along the forest edges.
The study holds potential good news for species like the pink-billed parrotfinch, banded iguana and Fijian land snails which live deep within Fiji's remaining forests. By using bait stations designed to attract rats and mongoose, the researchers discovered that stations over five kilometers (approximately three miles) from the forest edge were rarely visited.
"Protection of the few remaining large blocks of natural forests on Pacific islands may be the most cost-effective approach for conserving many rare species threatened by rats and mongooses," said WCS researcher David Olson, lead author of the study.
Though the authors are unsure on exactly why rats and mongoose seem to shy away from deep forests, they theorize that natural forests have poorer habitats for reproduction for these invasive species than agricultural areas or secondary forests.
The authors warn that even low levels of rat and mongoose penetration into forest areas can be sufficient over time to cause the decline of native species. Also, the occurrence of logging roads or even the proximity to rivers can allow rats and mongoose to colonize areas where endangered species occur.
"Remote forest areas that function as refuges for threatened island species are increasingly rare and should receive the highest priority for conservation on the larger islands of the Pacific," said David Olson, who said that similar forests exist in Vanuatu, New Caledonia, the Solomon Islands, Samoa, Hawaii and tropical islands in the Caribbean. Authors from the University of the South Pacific also contributed to the study.
