Resumen

Seabirds in the order of Procellariiformes have one of the highest proportions of threatened species of any avian order. Species undergoing recovery may be predicted to have a genetic signature of a bottleneck, low genetic diversity, or higher rates of inbreeding. The Hawaiian Band-rumped Storm Petrel (‘Akē‘akē; Hydrobates castro), a long-lived philopatric seabird, suffered massive population declines resulting in its listing under the Endangered Species Act in 2016 as federally Endangered. We used high-throughput sequencing to assess patterns of genetic diversity and potential for inbreeding in remaining populations in the Hawaiian Islands. We compared a total of 24 individuals, including both historical and modern samples, collected from breeding colonies or downed individuals found on the islands of Kaua‘i, O‘ahu, Maui, and the Big Island of Hawai‘i. Genetic analyses revealed little differentiation between breeding colonies on Kaua‘i and the Big Island colonies. Although small sample sizes limit inferences regarding other island colonies, downed individuals from O‘ahu and Maui did not assign to known breeding colonies, suggesting the existence of an additional distinct breeding population. The maintenance of genetic diversity in future generations is an important consideration for conservation management. This study provides a baseline of population structure for the remaining nesting colonies that could inform potential translocations of the Endangered H. castro.

Resumen

Abstract Hawaiian honeycreepers have radiated into a diversity of trophic niches and patterns of space-use. We investigated space-use in two honeycreeper species, the ‘Ākohekohe (Palmeria dolei), an endangered nectarivore, and Maui Parrotbill (Pseudonestor xanthophrys), an endangered wood excavator, by mapping the home ranges and dispersion of color-banded individuals at a study site in relatively undisturbed montane cloud forest on Maui Island, Hawai‘i. With 20% of outlying points excluded, home-range size averaged much smaller for adult male ‘Ākohekohe (0.56 ha) than for male Maui Parrotbill (2.26 ha). In both species, a female's home range mostly overlapped that of her mate. Adult male Maui Parrotbill defended year-round home ranges from which they excluded conspecifics except for their mates and dependent offspring. Although our data suggest that ‘Ākohekohe also maintained all-purpose territories, the evidence is less convincing because these birds were seen feeding in the home ranges of other individuals. By defending all-purpose territories, these two species depart from the more common honeycreeper pattern of sharing large, undefended home ranges. Rango de Hogar y Territorialidad en Dos Mieleros de Hawai, Palmeria dolei y Pseudonestor xanthophrys Resumen. Los mieleros de Hawai han radiado en una gran diversidad de nichos tróficos y patrones de uso del espacio. Investigamos el uso del espacio en dos especies amenazadas de mieleros, Palmeria dolei, un nectarívoro, y Pseudonestor xanthophrys, un excavador de madera. Mapeamos los rangos de hogar y dispersión de individuos marcadas con bandas de colores en un sitio relativamente no perturbado de bosque montano nublado, en la Isla Maui, Hawai. Excluyendo el 20% de los valores extremos, el tamaño promedio de los rangos de hogar de los machos adultos de P. dolei fue mucho menor (0.56 ha) que el de los machos de P. xanthophrys (2.26 ha). En ambas especies, el rango de hogar de la hembra se sobrepuso en gran parte al rango del macho. Los machos adultos de P. xanthophrys defendieron su territorio durante todo el año excluyendo a individuos conespecíficos con excepción de sus parejas y crías dependientes. A pesar que nuestros datos indican que P. dolei también mantuvo territorios, la evidencia es menos convincente debido a que estas aves fueron observadas forrajeando en rangos de hogar de otros individuos. Las dos especies estudiadas defienden sus territorios, lo cual las diferencia del patrón común observado en los mieleros, que consiste en compartir extensos rangos de hogar no defendidos.

Resumen

Abstract Extinction rates for island birds around the world have been historically high. For forest passerines, the Hawaiian archipelago has suffered some of the highest extinction rates and reintroduction is a conservation tool that can be used to prevent the extinction of some of the remaining endangered species. Population viability analyses can be used to assess risks to vulnerable populations and evaluate the relative benefits of conservation strategies. Here we present a population viability analysis to assess the long-term viability for Maui parrotbill (Kiwikiu) Pseudonestor xanthophrys, a federally endangered passerine on the Hawaiian island of Maui. Contrary to indications from population monitoring, our results indicate Maui parrotbills may be unlikely to persist beyond 25 y. Our modeling suggests female mortality as a primary factor driving this decline. To evaluate and compare management options involving captive-rearing and translocation strategies we made a female-only stage-structured, meta-population simulation model. Maui parrotbills have low reproductive potential in captivity; therefore, the number of individuals (∼20% of the global population) needed to source a reintroduction solely from captive reared birds is unrealistic. A reintroduction strategy that incorporates a minimal contribution from captivity and instead translocates mostly wild individuals was found to be the most feasible management option. Habitat is being restored on leeward east Maui, which may provide more favorable climate and habitat conditions and promote increased reproductive output. Our model provides managers with benchmarks for fecundity and survival needed to ensure reintroduction success, and highlights the importance of establishing a new population in potentially favorable habitat to ensure long-term persistence.

Resumen

Abstract We examine the genetic history and population status of Hawaiian hoary bats (Lasiurus semotus), the most isolated bats on Earth, and their relationship to northern hoary bats (Lasiurus cinereus), through whole-genome analysis of single-nucleotide polymorphisms mapped to a de novo-assembled reference genome. Profiles of genomic diversity and divergence indicate that Hawaiian hoary bats are distinct from northern hoary bats, and form a monophyletic group, indicating a single ancestral colonization event 1.34 Ma, followed by substantial divergence between islands beginning 0.51 Ma. Phylogenetic analysis indicates Maui is central to the radiation across the archipelago, with the southward expansion to Hawai‘i and westward to O‘ahu and Kaua‘i. Because this endangered species is of conservation concern, a clearer understanding of the population genetic structure of this bat in the Hawaiian Islands is of timely importance.

Resumen

Effective control of introduced mammalian predators is essential to the recovery of native bird species in Hawai?i. Between August 1996 and December 2004, introduced rodents were controlled within three home ranges of the Po?ouli Melamprosops phaeosoma, a critically endangered Hawaiian honeycreeper. Rats were controlled using a combination of ground-based rodenticide (0.005% diphacinone) application and snap traps. Beginning in August 2001, we monitored the effectiveness of these rodent control efforts. Relative abundances of Black Rats Rattus rattus and Polynesian Rats R. exulans were measured in each of five snap-trapping grids seven times over a 35-month period. Rat populations decreased inside of the rodent control areas, but control effectiveness differed between rat species. During the first year of monitoring, target control levels for R. rattus were consistently achieved in only one of the rodent control areas. Control techniques were refined in areas failing to meet targets. Subsequently, we achieved target control levels for R. rattus more consistently in all three rodent control areas. However, relative abundances of R. exulans did not differ between rodent control and reference areas, indicating that our rodent control techniques were insufficient to reduce population levels of this species. These findings signify a need for further improvement of rodent control methods in Hawai?i, especially for Polynesian Rats, and demonstrate the critical importance of periodic monitoring of the response of rodent populations to management. In the future, managers may need to design rodent control operations targeting R. rattus and R. exulans independently to achieve best results.

Resumen

SummaryThe accurate estimation of key demographic parameters is invaluable for making decisions about the management of endangered wildlife but such estimates are often difficult to obtain. Parameters such as species-specific apparent survival rates are an important component in understanding population ecology and informing management decisions. The Maui Parrotbill Pseudonestor xanthophrys is a ‘Critically Endangered’ Hawaiian honeycreeper endemic to the Island of Maui. We used an 18-year encounter history dataset comprising 146 marked individuals to estimate apparent survival between sexes and age classes (juvenile, adult). A difference in survival rates between sexes was strongly supported; 0.72 ± 0.04 for adult females and 0.82 ± 0.03 for adult males. This difference may be a reflection of either reproductive costs or additional risks of incubation and brooding, such as depredation. We also found support for age-biased survival, but limited information for juveniles did not provide a well-supported model fit for our data (juvenile survival = 0.17 ± 0.15; adults = 0.78 ± 0.02). However, apparent adult survival was similar to that of other Hawaiian passerines (mean 0.78 ± 0.03, n = 16). These results suggest that efforts to prevent the extinction of this species may benefit from future management strategies focused on increasing female survival such as predator reduction.

Resumen

AbstractThe ‘Ākohekohe (Palmeria dolei) is an endangered Hawaiian honeycreeper endemic to the montane rain forests of east Maui in the Hawaiian Islands. We investigated ‘Ākohekohe nesting ecology using color-banded birds for the first time as a background to understanding the species' conservation. From 1994–1997, we color-banded 78 individuals, located and monitored 46 active nests, and took behavioral data during 534 hr of nest observation at Hanawī Natural Area Reserve, near the center of the species' range. ‘Ākohekohe nesting behavior and life history closely resembled that of ‘Apapane (Himatione sanguinea) and related honeycreepers. The birds were monogamous within and among years, and we found no evidence of polyandry, polygyny, or helpers at the nest. The nesting season extended from November to early June. Females performed all incubation and brooding. Males provisioned females and nestlings, and they were more active than females in feeding fledglings during the two-week period of parental dependency. Modal clutch size, as determined from egg counts at three nests and by counting begging chicks at other nests, was two eggs, and parents frequently fledged two chicks. We found an overall nest success rate of 68% by the Mayfield method, a high rate compared with other Hawaiian honeycreepers and continental passerines. An average of 1.1 chicks fledged per active nest, and at least 42% of nesting pairs made two or more nesting attempts per season. Rats (Rattus spp.) were abundant at the study site, and we confirmed their depredating some ‘Ākohekohe nests, so we did not expect to find such a high rate of nest success. The estimated annual probability of adult survival was also high, at 0.95 ± 0.10 (SE).Ecología Reproductiva y Demografía de Palmeria doleiResumen. Palmeria dolei es una especie de mielero amenazada endémica de las selvas nubladas de montaña del Este de Maui en las Islas de Hawai. Investigamos la ecología de nidificación de esta especie usando aves marcadas con anillos de colores como antecedente para entender la conservación de la especie. Entre 1994–1997 marcamos 78 individuos, localizamos y monitoreamos 46 nidos activos, y recolectamos datos de comportamiento durante 534 hr de observación de nidos en la Reserva Natural Hanawī, cercana al centro del rango de distribución de la especie. El comportamiento de nidificación y la historia de vida de P. dolei son marcadamente similares a los de Himatione sanguinea y otros mieleros relacionados. Las aves fueron monógamas dentro y entre años, y no hallamos evidencias de poliandría, poliginia, o ayudantes en los nidos. La estación de nidificación se extendió desde noviembre hasta principios de junio. Las hembras realizaron toda la incubación y cuidado de la nidada. Los machos aprovisionaron a las hembras y pichones, y fueron más activos que las hembras en alimentar a los volantones durante las dos semanas que dependen de los padres. La moda del tamaño de la nidada, determinada a partir del conteo de huevos en tres nidos y del recuento de gritos de llamada de pichones, fue de dos huevos, y los padres generalmente lograron criar dos pichones. Encontramos una tasa de éxito global de los nidos del 68% estimada con el método Mayfield, lo que representa una alta tasa comparada con la de otros mieleros hawaianos y paseriformes continentales. Un promedio de 1.1 pichones por nido activo llegaron a la etapa de dejar el nido, y al menos 42% de las parejas nidificantes realizaron dos o más intentos de nidificación por estación. Ratas (Rattus spp.) fueron abundantes en el sitio de estudio, y confirmamos que depredan nidos de P. dolei, por lo que no esperabamos obtener una tasa de éxito de nidificación tan alta. La probabilidad estimada de supervivencia de los adultos fue también alta, 0.95 ± 0.10 (ES).

Resumen

AbstractBlackburnia gastrellariformis sp. n., is described from East Molokai, Hawaii. Based on cladistic parsimony analysis of adult characters, the species is hypothesized to be most closely related to B. komohana Liebherr & Zimmerman of West Maui, with these two species comprising the adelphotaxon to the East Maui species pair, B. haleakala Liebherr & Zimmerman + B. putealis (Blackburn). Previous reconciled tree analysis for the Hawaiian Blackburnia radiation conducted before discovery of B. gastrellariformis found a general pattern in which Molokai and West Maui were hypothesized as sister-areas to the exclusion of the East Maui volcano, Haleakala, though the less common, incongruent area relationship of (Molokai (West Maui + East Maui) was also represented in the taxon-area cladogram. In the present reconciled tree analysis, the closest hypothesized relationship of B. gastrellariformis and a West Maui species corroborates the more common pattern by replacing items of error in the previous analysis with the newly discovered species. Elevational habitat shifts are invoked to explain the occurrence of numerous sister-species pairs in Molokai and West Maui, currently separated by the Pailolo Channel, relative to species occupying Haleakala.

Resumen

Inoculations of Septoria passiflorae for biological control of banana poka (Passiflora tripartita var. tripartita) at different forest sites in Hawaii, Kauai, and Maui resulted in successful establishment of the Septoria leaf spot disease at all sites during 1996. Semi-annual monitoring of sites in 1997 revealed low disease incidence and no disease spread to adjacent non-inoculated plants. Site inspections in March 1998 revealed light disease epidemics causing visible defoliation at inoculated sites on Kauai and Maui. Banana poka biomass reduction at sites with light epidemics of the disease in Kauai and Maui were estimated to be less than 10% in 1998, whereas in 1999 biomass reduction ranged from 50 to 95%. Five of 11 inoculation sites in 1996 on the island of Hawaii showed no disease. These five sites on Kaloko had frequent acid rainfall averaging 3.2 pH, which inhibited spore germination and infection. Six sites, free of acid rain, three at Hilo Forest Reserve and three at Puuwaawaa Wildlife Sanctuary, had severe disease epidemics by 1998, and vine defoliation was >90%. Widespread epidemics of the disease occurred in 1999, resulting in estimated 80 to 95% biomass reductions in more than 2,000 hectares of native forest infested with banana poka.

Resumen

The Carolina hemlock (Tsuga caroliniana) survives in just a few rocky streambeds along the lower slopes of the Blue Ridge Mountains. Other species of hemlock abound across the United States, but none bear a close resemblance to this particular tree. The closest relatives of the Carolina hemlock, in fact, survive in only one other forest on Earth, some 7,000 miles away in Hubei province of eastern China. The forests of eastern Asia and eastern North America are so similar that if you were suddenly transported from one to the other, you would be hard-pressed to tell them apart. In the swift mountain streams rushing past these seemingly displaced hemlocks live a number of small, colorful fish known as darters. Darters are found only in North America and have evolved into a prolific variety of fishes. Up to 175 species inhabit U.S. waters, including the famous snail darter (Percina tanasi), which brought endangered species issues to the fore when it held up construction of the Tellico Dam on the Little Tennessee River. How is it that these two organisms, hemlock and darter, one with its closest relatives on the other side of the globe and the other found nowhere else in the world, came to be living side by side? Just how many plants and animals share the piece of Earth that we know as the United States of America? Why these and not others? These are central questions for understanding the diversity of the nation’s living resources. The United States encompasses an enormous piece of geography. With more than 3.5 million square miles of land and 12,000 miles of coastline, it is the fourth largest country on Earth, surpassed only by Russia, Canada, and China. The nation spans nearly a third of the globe, extending more than 120 degrees of longitude from eastern Maine to the tip of the Aleutian chain, and 50 degrees in latitude from Point Barrow above the Arctic Circle to the southern tip of Hawaii below the tropic of Cancer. This expanse of terrain includes an exceptional variety of topographic features, from Death Valley at 282 feet below sea level to Mt. McKinley at 20,320 feet above sea level.
