This quarter’s issue of Pacific Science includes Demography of Marine Turtles in the Nearshore Environments of the Northern Mariana Islands, an open-access article; and an online-only supplemental for Methods for Measuring Bird-Mediated Seed Rain: Insights from a Hawaiian Mesic Forest.
In the western Pacific, green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) sea turtles are listed as Endangered under the U.S. Endangered Species Act (ESA). Population data are limited for both species throughout the entire region and particularly in the Philippine Sea. This study characterizes size class distribution, growth rates, habitat use, behavior, diet, and site fidelity of foraging aggregations of green and hawksbill turtles in nearshore habitats of Saipan, Tinian, and Rota in the Commonwealth of the Northern Mariana Islands (CNMI ). Between August 2006 and February 2014, we captured 642 turtles (493 green and 36 hawksbill turtles). … This is the first study within the CNMI to report on morphometric data and diet composition of marine turtles. These results provide an assessment of green and hawksbill turtle population demographics and habitat use in the CNMI.
This quarterly issue of Pacific Scienceexplores new research about Pacific crabs, fish, plankton, birds, grass, frogs, and eels.
The opening article examines fish in the aftermath of the 2011 Tohoku 9.0 magnitude earthquake and tsunami at the Fukushima Daiichi Nuclear Power Plant. From the abstract:
Thirteen commonly consumed types of fish caught in the North Pacific and locally available in Hawai‘i were analyzed using gamma spectroscopy to measure Fukushima-derived and historic 134Cs and 137Cs isotopes. All fish samples had detectable 137Cs above 95% confidence intervals. Three out of the thirteen samples had 134Cs, an isotope indicative of Fukushima releases, detected above 95% confidence intervals. The highest 134Cs and 137Cs concentration in the examined species was in ‘ahi tuna, carrying 0.10 ± 0.04 Bq/ kg and 0.62 ± 0.05 Bq/ kg, respectively. Other samples with 134Cs activities found above their 2-sigma uncertainty were albacore tuna and swordfish. Historic and Fukushima-derived contributions were evaluated, and in several samples the Fukushima-derived radiocesium dominated the total radiocesium inventory with up to 61% contribution. All activities were below derived intervention limits of 1,200 Bq/ kg, and the doses to humans from consuming the fish attributable to radiocesium were 0.02 – 0.2 μ Sv, in comparison to 6 – 20 μ Sv contributed by the natural 40K present in the same fish.
Also inside this quarter’s issue, Wyatt A. Shell examines small green carpenter bee range expansion in Hawai’i:
Invasive bee species may have a widely detrimental impact on their novel host ecosystem. Introduced bees can rapidly disrupt native plantpollinator mutualisms through competition with indigenous pollinator fauna and facilitation of invasive flora reproduction. […] Here we present a comprehensive synthesis of C. smaragdula’s known biological and ecological history, as well as a population genetic analysis of C. smaragdula from Maui, and from locations across its native range, at the cytochrome oxidase I (COI ) locus. We update C. smaragdula’s known distribution and occurrence elevation in Hawai‘i and reveal a lack of genetic structure between Hawaiian and native range populations.
This issue of MĀNOA (28-1), Curve of the Hook: An Archaeologist in Polynesia is a booklength interview with Dr. Yosihiko Sinoto, known for the astonishing archaeological discoveries that changed our ideas of the ancient Polynesians, their ways of life, and their legendary voyages across the Pacific. Dr. Sinoto’s discoveries included whale-tooth pendants, stone tools and weapons, sacred structures, dwellings, an ancient voyaging canoe, and finely made fishhooks that allowed him and his fellow archaeologists to chart the seafaring routes of early Polynesians.
Now, in Curve of the Hook, we can experience the extraordinary adventures and career of an eminent and celebrated archaeologist in Polynesia. This full-color book includes over 100 illustrations—including unpublished photos from Dr. Sinoto’s private collection—plus notes and a list of references.

University of Hawai’i Press is pleased to announce that Press journal editor Roger Ames has been recognized for his expertise in Chinese philosophy as a recipient of the Huilin Culture Award. Ames, the editor of Philosophy East and West, recently ended his tenure as editor of China Review International over a decade after founding the publication, and accepted the award in Beijing on February 27.
The award committee cited Professor Ames’ extensive work in comparative philosophy, research on Chinese philosophy and his publications on Confucianism, including The Chinese Classic of Family Reverence, Sun Tzu: The Art of War, and a philosophical translation of the Daodejing. Many of his titles have become classics in the study of Chinese philosophy.
