Download or read book Conservation Biology of Hawaiian Forest Birds written by Thane K. Pratt and published by Yale University Press. This book was released on 2009-01-01 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hawaii’s forest bird community is the most insular and most endangered in the world and serves as a case study for threatened species globally. Ten have disappeared in the past thirty years, nine are critically endangered, and even common species are currently in decline. Thane K. Pratt, his coeditors, and collaborators, all leaders in their field, describe the research and conservation efforts over the past thirty years to save Hawaii’s forest birds. They also offer the most comprehensive look at the reasons for these extinctions and attempts to overcome them in the future. Among the topics covered in this book are trends in bird populations, environmental and genetic factors limiting population size, avian diseases, predators, and competing alien bird species. Color plates by award-winning local photographer Jack Jeffrey illustrate all living species discussed or described.
Download or read book Dream Nation written by María Acosta Cruz and published by Rutgers University Press. This book was released on 2014-03-19 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past fifty years, Puerto Rican voters have roundly rejected any calls for national independence. Yet the rhetoric and iconography of independence have been defining features of Puerto Rican literature and culture. In the provocative new book Dream Nation, María Acosta Cruz investigates the roots and effects of this profound disconnect between cultural fantasy and political reality. Bringing together texts from Puerto Rican literature, history, and popular culture, Dream Nation shows how imaginings of national independence have served many competing purposes. They have given authority to the island’s literary and artistic establishment but have also been a badge of countercultural cool. These ideas have been fueled both by nostalgia for an imagined past and by yearning for a better future. They have fostered local communities on the island, and still helped define Puerto Rican identity within U.S. Latino culture. In clear, accessible prose, Acosta Cruz takes us on a journey from the 1898 annexation of Puerto Rico to the elections of 2012, stopping at many cultural touchstones along the way, from the canonical literature of the Generación del 30 to the rap music of Tego Calderón. Dream Nation thus serves both as a testament to how stories, symbols, and heroes of independence have inspired the Puerto Rican imagination and as an urgent warning about how this culture has become detached from the everyday concerns of the island’s people.

Download or read book Invasive Coqui Frogs Serve as Novel Prey for Birds in Hawaii and Not as Competitors written by Robyn L. Smith and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Puerto Rican coqui frog (Eleutherodactylus coqui) has been hypothesized to affect bird communities in Hawaii by 1) competing with insectivorous birds for prey, 2) providing prey for predatory birds, and 3) bolstering populations of non-native mammals by serving as prey. No previous studies have collected empirical data on these potential impacts. We investigated the impact of coquis on birds at two scales. For our first research question, we used stable isotope analyses to address whether three species of insectivorous bird, one native and two non-native, and coquis could compete for invertebrate prey. We found that the coquis overlapped in isotopic niche space with all three bird species, which suggests these species occupy a similar place in the food web. However, our Bayesian diet analysis suggests that coquis mostly feed on Acari, Amphipoda, and Blattodea (>90%), and only consume about 2% Araneae, the only diet source they share with birds. This result suggests that coquis do not heavily compete with these bird species for prey. For our second research question, we conducted avian point counts in coqui and non-coqui plots across 15 sites on the island of Hawaii. We modeled whether coqui presence or density explained patterns of insectivorous, vertebrate-preying, and native bird abundance. We estimated abundances of birds in coqui and non-coqui plots using hierarchical Bayesian N-mixture models with random effects. We tested whether habitat variables differed across coqui and non-coqui plots and whether coqui density was correlated with any habitat variable to more confidently attribute changes in bird abundance across coqui and non-coqui plots to the frogs. We found that coquis were associated with greater abundances of vertebrate-preying, generalist insectivorous, and non-native birds in Hawaii. Vertebrate-preying birds showed the strongest association, with a 0.97 probability of abundance being at least 50% higher in coqui plots. Native birds did not show differences in abundance across coqui and non-coqui plots. Because insectivorous bird and native bird abundance did not differ across coqui invasion fronts, our results suggest that coquis primarily affect Hawaiian birds by serving as a food resource for predatory birds, and not as competitors for invertebrate prey.
Download or read book Diet Density and Distribution of the Introduced Greenhouse Frog Eleutherodactylus Planirostris on the Island of Hawaii written by Christina A. Olson and published by . This book was released on 2011 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The greenhouse frog, Eleutherodactylus planirostris, native to Cuba and the Bahamas, was recently introduced to Hawaii. Studies from other invaded habitats suggest that it may impact Hawaiian ecosystems by consuming and potentially reducing endemic invertebrates. However, there have been no studies on the greenhouse frog in Hawaii. The first component of this study was to conduct a diet analysis. We conducted a stomach content analysis of 427 frogs from 10 study sites on the island of Hawaii. At each site, we also collected invertebrates using two different sampling methods: leaf litter collection and sticky traps to characterize available resources. Greenhouse frogs consumed predominantly leaf litter invertebrates. Dominant prey items consisted of Hymenoptera: Formicidae (32.4%), Acari (19.2%), and Collembola (17.4%). Greenhouse frogs consumed more Formicidae than was measured in the environment. At one study site, we estimated there were 12,500 frogs ha-1 using mark-recapture methods and greenhouse frogs consumed 129,000 invertebrates ha-1 night-1 at this site. The second component of this study was to determine the distribution of the greenhouse frog on the island of Hawaii, with a male breeding call presence/absence survey at 446 points along the major road network. The greenhouse frog was detected at 61 sites (14%), and found mostly in lowland areas, in habitats of native shrublands and forests, nonnative forests, agricultural lands, and pastures on the southwestern and eastern sides of the island. We determined detection probabilities of the greenhouse frog and the invasive coqui frog, E. coqui. Detection probability of the greenhouse frog was low on the first two surveys and improved by the third survey. Detection probability of the coqui was higher than the greenhouse frog, but overall site occupancy estimates were similar for both species. Because the greenhouse frog appears to be as widespread as the coqui, we recommend that research be conducted to investigate its impacts ecologically to determine whether control efforts should also be aimed at this species.

Download or read book Cane Toad Wars written by Rick Shine and published by Univ of California Press. This book was released on 2018-03-20 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1935, an Australian government agency imported 101 specimens of the Central and South American Cane Toad in an attempt to manage insects that were decimating sugar-cane harvests. In Australia the Cane Toad adapted and evolved with abandon, voraciously consuming native wildlife and killing predators with its lethal skin toxin. Today, hundreds of millions of Cane Toads have spread across the northern part of Australia and continue to move westward. The humble Cane Toad has become a national villain. Cane Toad Wars chronicles the work of intrepid scientist Rick Shine, who has been documenting the toad’s ecological impact in Australia and seeking to buffer it. Despite predictions of devastation in the wake of advancing toad hordes, the author’s research reveals a more complex and nuanced story. A firsthand account of a perplexing ecological problem and an important exploration of how we measure evolutionary change and ecological resilience, this book makes an effective case for the value of long-term natural history research in informing conservation practice.

Download or read book Invertebrate Community Changes Along Coqui Invasion Fronts in Hawaii written by Ryan T. Choi and published by . This book was released on 2011 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Puerto Rican coqui frog, Eleutherodactylus coqui, was introduced to Hawaii in the late 1980s via the commercial horticulture trade. Previous research has shown that coquis can change invertebrate communities, but these studies were conducted at small scales using controlled, manipulative experiments. The objective of this research was to determine whether coqui invasions change invertebrate communities at the landscape scale across the island of Hawaii. At each invasion front, we measured environmental variability on either side of the front and removed sites that were too variable across the front to ensure that the impacts we measured were the result of the invasion. After doing this, there remained 15 sites for which we compared invertebrate communities in 30 m x 30 m plots situated on either side of coqui invasion fronts. In each plot, we collected invertebrate samples from three invertebrate communities, the leaf litter, foliage, and flying invertebrate communities. Multivariate analyses show that coqui frogs change leaf litter communities, by reducing microbivore and herbivore abundances. Coqui also change flying community composition, but have no measurable effect on foliage communities. Across sites, we found that coquis reduced the number of leaf litter invertebrates by 27%, and specifically abundant Acari by 36%. We also found that coquis increased the abundance of flying Diptera by 19% across sites. We suggest that the leaf litter community is altered through direct coqui predation and that Diptera increase because of increased frog carcasses and excrement in invaded plots. Results support previous studies conducted in more controlled settings, but add to our understanding of the invasion by demonstrating that coqui effects on invertebrate communities are measurable at the landscape scale.
