A visual interpretation for a spatial model of the social-ecological zones (wao kanaka, wao lā`au, wao nāhele, wao kele, wao akua) implemented during the aliʻi-era for the ahupuaʻa of Hāʻena, Haleleʻa, Kauaʻi. This model is being used by contemporary resource managers to inform large-scale biocultural conservation and forest restoration efforts within this social-ecological system (see Winter & Lucas, this issue for additional details; image credit: Ben Nyberg).

The October 2017 issue of Pacific Science begins with a Special Feature, which includes seven open-access articles available on Project MUSE and Bio-One.

Clockwise from bottom left: nearshore capture locations in relation to benthic habitat of ( A) Saipan, (B) Tinian, and (C ) Rota, and (D) an image of the free diver hand capturing a juvenile green turtle. Green and orange dots depict capture locations for green and hawksbill turtles, respectively. Shading indicates benthic habitat.

 

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.

The open-access article examines honu:

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 Science explores 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.

New Species of Stylasterid (Cnidaria: Hydrozoa: Anthoathecata: Stylasteridae) from the Northwestern Hawaiian Islands by Stephen D. Cairns

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.

On the Origin of Sympatric Fruit Doves in a Small and Remote Pacific ArchipelagoNo Access
Alice Cibois, Jean-Claude Thibault, Jean-Yves Meyer and Eric Pasquet, 299ps.69.3_cover

Abstract: Fruit doves of the genus Ptilinopus (Columbidae) form a large group of more than 50 species that have been successful in colonizing most of the Pacific Ocean, with sympatric species on several small oceanic islands. A recent new phylogeny of this genus and allies by Cibois and coworkers showed that all these cases of sympatry derived from multiple independent colonizations, with the exception of the Marquesas Islands (eastern Polynesia), where the two fruit doves that occurred sympatrically are sister species: the Red-moustached Fruit Dove, Ptilinopus mercierii, and the White-capped Fruit Dove, Ptilinopus dupetithouarsii. Both Marquesas fruit doves coexisted on several Marquesas islands until the recent extinction of the Red-moustached Fruit Dove. Here, we analyze their morphology, review their life history, and discuss the two most likely scenarios for the divergence of the two species, in light of the geological history of the Marquesas hot-spot volcanoes (5.5–1.1 Ma). The microallopatry scenario takes into account the large initial size of the islands and involves partitioning of the fruit doves’ distributions within the same island, whereas in the intra-archipelago scenario, the birds’ speciation occurred on different islands, in conjunction with their sequential emergence. We discuss both hypotheses and conclude that estimated time of divergence of the two species and known ecology of the birds favor the intra-archipelago scenario.

Biology and Impacts of Pacific Island Invasive Species. 11. Cinchona pubescens (Red Quinine Tree) (Rubiaceae)PacificScience69_2cover
Heinke Jäger, 133

Abstract: Cinchona pubescens Vahl (red quinine) is an evergreen tree ranging in height from 10 to 25 m with broad leaves and white or pink fragrant flowers arranged in clusters. Growing at altitudes between 130 and 3,300 m, it is one of 23 species in the genus Cinchona and has a natural distribution from Costa Rica to Bolivia. Cinchona pubescens has been cultivated in tropical regions (e.g., in South America, Africa, China, India, and Indonesia) for its quinine-containing bark and has become invasive in some regions. This is especially the case in the Pacific region, where C. pubescens has invaded humid highland areas of Galápagos, Hawai‘i, and Tahiti. It shades out and reduces cover of native plant species and adversely affects endemic birds. In addition, it changes microclimate and nutrient cycling in the soil, especially phosphorus, in Galápagos. Characteristics that make it such a successful invader include production of numerous, windborne seeds and vigorous vegetative reproduction by resprouting from underground stems and fallen trees. In Galápagos, C. pubescens is currently being manually controlled by uprooting the trees and by applying herbicides to cuts in the bark. However, this method requires continuous hand pulling of seedlings to be successful. Disturbance by control actions appears to facilitate establishment and invasion by other nonnative plant species, especially blackberry (Rubus niveus). Quinine and other alkaloids extracted from Cinchona bark are still being used for medicinal purposes today and the wood is increasingly used as construction material in Galápagos. Ironically, C. pubescens is now considered rare and endangered in its native range in Ecuador.
