Available in PDF, EPUB and Kindle. Book excerpt: Eastern white pine (Pinus strobus L.) is experiencing novel symptoms of dieback and mortality throughout its range in North America. Recent studies have found that two organisms, a fungal pathogen (Caliciopsis pinea Peck) and a scale insect (Matsucoccus macrocicatrices Richards), have emerged in association with a canker disease, which is driving the symptoms of this dieback phenomenon. Little is known about this insect-pathogen complex and its relationship to its host, including the colonization tendencies of the insect and pathogen, the nativity of the insect, and the genetic diversity and structure of the host in the Southern Appalachians region. I quantified the incidence of scale insects and pathogenic cankers within trees and among size classes and found that colonization of both the insect and the pathogen was consistent with the patterns of dieback and mortality of P. strobus, adding support to the hypothesis that these organisms are responsible for dieback symptoms and mortality. I also developed microsatellite markers to evaluate the present genetic diversity and structure of M. macrocicatrices populations within a biogeographical framework. I found that this insect is native to all regions in North America, and I posit it has likely been co-occurring with P. strobus, its obligate host, since the last glacial maximum. Therefore, recent introductions and invasional processes likely did not contribute to the recent emergence of M. macrocicatrices and its novel association with pathogens and dieback symptoms. Lastly, I elucidated the genetic diversity and population structure of P. strobus in the understudied Southern Appalachians and found that populations in this region are highly variable but not more so than those in more northern latitudes. Although this important tree species faces new threats, its high genetic variation suggests it may also have a substantial amount of adaptive potential. My results and interpretations herein provide comprehensive and important foundational knowledge about the organisms involved in the eastern white pine dieback phenomenon. This research has built a framework for future investigations into (1) the mechanism(s) that allows M. macrocicatrices to facilitate C. pinea infection, (2) the reason(s) why M. macrocicatrices has recently emerged as a pest, and (3) the appropriate management and conservation strategies for P. strobus persistence in its native range.

Available in PDF, EPUB and Kindle. Book excerpt: In this follow-up to Islands and Snakes, this book contains 15 chapters describing diversity and conservation of snakes on islands, with foci on selected island systems not previously summarized. Attendant topics include biogeography, plasticity and evolutionary responses to insular conditions, invasive species, importance and collapse of trophic systems, threats to insular snake populations, and strategies of conservation to save them. Chapters include descriptions of snake faunas on larger islands such as Borneo and New Guinea; reproductive biology of insular snakes; phenotypic evolution; physiology and growth patterns related to diet and environment; patterns of endemism; taxonomy of snake radiations; and history of invasions by snakes on islands. The final chapter presents a discussion of prospects and overview of conservation of snakes on islands. Chapters are contributed by international authorities on respective island-and-snake systems. The latter include some islands or archipelagos that are young, or of high importance, or support snake populations that were previously not well known. The content includes colourful photographs, informative illustrations, and in some cases synthesis of new data relevant to the importance of islands for understanding the ecological underpinnings and genesis of biodiversity. Each chapter is appropriately referenced with citations to scientific literature, and where useful, footnotes, tables and graphic information supporting the narrative of the respective subject matter. The overall presentation is intended to provide readers with an enhanced appreciation for islands and the spectacular snakes that might live there.
