Resumen
Because of the large number of potentially invasive species, and the time required to complete weed risk assessments (WRAs) with the use of the current, mandated system in the United States, species need to be prioritized for assessment and possible listing as Federal Noxious Weeds. Our objective was to rank the potential invasiveness of weedy or pest plant species not yet naturalized in the United States. We created a new model of invasiveness (hereafter the U.S. weed-ranking model) based on scoring factors within four elements: (1) invasiveness potential, or likelihood to exhibit invasive behavior; (2) geographic potential, or habitat suitability; (3) damage potential, or likely impact; and (4) entry potential, or likelihood to be introduced. The ranking score was the product of the four elements. We scored 250 species satisfactorily, from a list of 700 +. We analyzed model sensitivity to scoring factors, and compared results to those from a WRA model for Hawaii. For species not in cultivation in the United States, the top 25 species included a mix of annuals, perennials, sedges, shrubs, and trees. Most had exhibited invasive behavior in at least several other countries. Because of greater entry potential scores, the highest-scoring species were weeds in cultivation. Twenty-nine such species, out of 44 total, had scores greater than the highest scoring species not in cultivation. In comparison to the Hawaii WRA model, correlation and regression analyses indicated that the U.S. weed-ranking model produced similar, but not exact, results. The ranking model differs from other WRAs in the inclusion of entry potential and the use of a multiplicative approach, which better suited our objectives and United States regulations. Two highly ranked species have recently been listed as Federal Noxious Weeds, and we expect most top-tier species to be similarly assessed.

Resumen
Azolla (Azolla filiculoides) is a floating fern that maintains a symbiotic relationship with an N-fixing blue-green algae. In many parts of Asia, azolla is used as a green manure in flooded rice cultivation. Taro (Colocasia esculenta) grown under flooded conditions is used to produce a traditional Hawaiian staple, poi. Azolla has been present in Hawaii for many years, but is not used in a controlled way for either nutrient augmentation of production sites or weed suppression. In this experiment, azolla was removed from a stream on the island of Kauai and multiplied in a nursery pond. Phosphoric acid was added to the nursery pond as a nutrient (P = 5 ppm) at 5-day intervals to accelerate azolla growth. Azolla was moved from the nursery pond and added to taro production plots at a seeding rate of 488 kg·m–2. Phosphoric acid was used in production plots to hasten coverage of the water surface by azolla. Ten days after azolla inoculation, production plots were covered and taro seed pieces were planted. Weed dry weights from conventional and azolla covered plots were recorded 91 days after taro planting. Taro corms were harvested 315 days after planting. Weed dry weight in azolla plots was 86% less than conventional plots. Azolla delayed taro maturity, causing a 41% reduction in marketable corm yield.

Resumen
AbstractThe potential distribution of the South African weevil, Perapion antiquum (Gyllenhal), a biological control agent for the weeds Emex spp., was deter mined by the computer program CLIMEX, using its native distribution, phenology and abundance together with development parameters. The predicted distribution included parts of Hawaii where the weevil successfully controlled Emex australis and E. spinosa. In Australia, sites of past unsuccessful releases have climates that this analysis indicates are unsuitable for the insect. The most favourable regions for establishment of the weevil are near the coast in the southern half of Australia, but most of these do not overlap with regions where Emex spp. are a problem. In western Cape Province, South Africa, E. australis plants are abundant and the weevil attacks the plant after seeds have formed. In Hawaii, a fortuitous combination of climatic conditions favours the weevil during the period after seed germination, and this may be the key to its control of the weed. Sites with climatic conditions similar to successful control sites in Hawaii are not found in Australia. It was concluded that P. antiquum will be of limited use as a biological control agent in Australia even in areas suitable for its establishment.

Resumen
Pejibaye (Bactris gasipaes Kunth) is being evaluated in Hawaii for production of fresh heart-of-palm. Yields and offshoot (sucker) production were evaluated in response to woven black polypropylene mat (control), three legumes [Arachis pintoi Krap. & Greg., Cassia rotundifolia Pers., and Desmodium heterocarpon (L.) DC], and a grass (Chloris gayana Kunth) used as ground covers. D. heterocarpon and C. gayana formed closed canopies quickly and controlled weeds well, but required more frequent mowing. A. pintoi formed a closed canopy slowly and only controlled weeds after forming a thick canopy, but required less mowing. Cassia rotundifolia died out after flowering and setting seed. All vegetative ground covers delayed heart-of-palm harvest and had reduced yields 1.5 years after planting. A combination of polypropylene (adjacent to plants) and vegetative ground covers (in service rows) may provide the best solution to minimizing labor for vegetative management in this orchard crop.

Resumen
Species of the genus Schinus Linnaeus (1753) (Anacardiaceae) are native to the Americas but are found in many tropical and subtropical parts of the world, where they are cultivated as ornamentals or crops (“pink peppercorns”) or they are invasive weeds. Schinus molle L. (1753: 388) is a cultivated ornamental tree in Australia, California, Mexico, the Canary Islands, the Mediterranean, and elsewhere (US Forest Service 2015). In Hawaii, Florida, South Africa, Mascarene Islands, and Australia, Schinus terebinthifolia Raddi (1820: 399) is an aggressively invasive pest plant, costing governments millions of dollars in damages and control (Ferriter 1997).

Resumen
Cyperus kyllingia and Cyperus brevifolius are problematic turfgrass weeds in Hawaii. Both are closely related weed species with similar morphology and growth characteristics. C. kyllingia appears to be a more successful weed with regards to interference than C. brevifolius. Greenhouse experiments were conducted to compare the levels of interference exerted by C. kyllingia and C. brevifolius upon Cynodon dactylon turfgrass. C. kyllingia reduced the growth of C. dactylon by about 50 %, while C. brevifolius did not significantly reduce C. dactylon growth. These results correspond with the chemical profiles of C. kyllingia and C. brevifolius. Analysis has shown that C. kyllingia contains two sesquiterpenes which have been identified as potentially allelopathic components of Cyperus rotundus. C. brevifolius contains waxes and the two sesquiterpenes found in C. kyllingia are absent. This suggests that allelopathy may be the mechanism responsible for the different levels of interference exhibited by C. kyllingia and C. brevifolius, and these species may provide an important model for the study of allelopathy.

Resumen
Two related species of Hedera spp. exist throughout Canada: English Ivy (Hedera helix L.) and Irish Ivy [Hedera hibernica (G. Kirchn.) Bean]. These species are difficult to distinguish taxonomically and clear distinctions are not always made in the literature, so we largely discuss them as a single taxon in this account. Ivy is an evergreen perennial with two distinct forms: woody vine (juvenile form) or shrub (adult form). In Canada, Hedera spp. are found naturalized along the southern coast of British Columbia (Vancouver, Vancouver Island, and the Gulf Islands) and in southwestern Ontario. During the past century, ivies have greatly expanded their ranges along the Pacific and Atlantic coasts of North America and in New Zealand, Australia, South Africa, Brazil, and Hawaii. Ivy is physiologically plastic, invading both semi-open and deeply shaded forests. It forms a dense ground cover that can inhibit native vegetation. It grows up on tree trunks and competes for soil nutrients, frequently leading to tree damage or even tree fall. Invasive characteristics include its evergreen habit, persistence, and vegetative reproductive capabilities. Humans have accelerated the spread of ivy by planting it along highway embankments and medians to control soil erosion and through widespread sale as an ornamental plant. There is debate among horticulturalists and ecologists over the destructive and advantageous effects of ivy growth and sale within North America. Various methods of control (chemical, manual, biological, and integrated) may be used to manage this species, but more research is needed to design better control techniques.

Resumen
This book analyzes the larger racial significance of the quick conviction and death sentence given to a likely insane Japanese American, Myles Fukunaga, for murdering a White boy, Gill Jamieson, in 1928. The Fukunaga case demonstrates how race operated in Hawai‘i to enforce the hierarchical relations between Whites and non-Whites. In arguing that Fukunaga was raced to death, two different meanings of race are employed. First, he was hanged because he was of the “Japanese race” and committed his crime during the 1920s, when Japanese Americans were perceived as the most politically and economically threatening group to continued White supremacy in Hawai‘i. Second, Fukunaga was raced or rushed to his death sentence less than three weeks after his crime because Whites wanted immediate revenge. The book argues that the Fukunaga case was a major component in a trajectory of racial injustice against non-Whites, including Japanese and Filipino labor leaders who, after organizing multiplantation strikes in 1920 and 1924, were imprisoned based on likely perjured testimony. Fukunaga’s hanging is also connected to the lynching in 1932 of Joe Kahahawai, a Native Hawaiian, who was falsely accused of raping a White woman and was also raced to death. The book also discusses how incipient forms of colorblindness and multiculturalism were strategically deployed by Whites to deny the significance of race in the accelerated conviction of Fukunaga.

Resumen
This chapter details Anna Botsford and John Henry Comstock's stay at a friend's family hotel on Waikiki Beach in Honolulu, Hawaii. The Comstocks were given a cottage on the hotel grounds where they had a living room of their own, which was especially convenient since they had so many callers. On the second day after their arrival, they were invited to lunch at the Globe Hotel as guests of the Pan-Pacific Club. In the weeks that followed, they were taken somewhere for an auto ride every day. There were five of Henry's former students who were doing entomological work on the island; they all put themselves and their automobiles at the Comstocks' service in the most generous manner. The Comstocks also attended the Hawaiian church and heard excellent sermons and music. The chapter then recounts their voyage to Europe in 1925.

Resumen
Ken Nedimyer is founder and president of the Coral Restoration Foundation. He has lived and worked in the Florida Keys for over forty years and has witnessed firsthand the degradation of the Florida Reef Tract. He established one of the largest coral nurseries in the world and has been training restoration groups, especially in the Caribbean, on how to use his unique coral tree technique. Nedimyer won multiple awards, including a CNN Hero in 2012 and a Disney Conservation Hero in 2014. I first interviewed him over the phone on January 4, 2016, then met him in person in Hawai‘i, and finally interviewed him a couple of weeks after Hurricane Irma hit the Florida Keys. Nedimyer is the only nonscientist among the interchapter interviews. His narrative is important, in my view, precisely because he is an outsider to that world, therefore providing a fresh reflection on both scientists and the existing legal regimes....
