Available in PDF, EPUB and Kindle. Book excerpt: "Forest canopies may harbour up to 50% of the world's diversity and since the canopy and forest floor have different architectures, the structure of arthropod assemblages may vary by stratum. This has implications for forest management since long-term logging practices can change the composition and structure of northeastern North American forests, and arthropods are sensitive to these differences. While canopy sampling is becoming more common, the interaction between forest management and vertical stratification in temperate forests in North America has remained relatively unexplored. The objective of this thesis is to explore and quantify the structure of arthropod communities in two strata within the context of forest management (time-since harvest and silvicultural technique). I used beetles (Coleoptera) and spiders (Araneae), important components of forest ecosystems, to test effects of vertical stratification and forest management effects on biodiversity and community structure. I collected 586 species of beetles and spiders, representing 11 137 individuals, over two field seasons in a deciduous hardwood forest in Southern Québec. Beetle diversity was influenced by height, with the understorey harbouring a higher abundance and species richness than the upper canopy. Spider diversity was not affected by height or forest management. Both beetle and spider community compositions were strongly affected by height, with each stratum supporting a different community. Beetle assemblages differed between forest management sites (both time-since harvest and silvicultural technique treatments), but this was largely influenced by the Latridiidae, the most commonly collected family. Spider assemblages did not change with forest management treatment. Responses were taxon dependent, at both the Order and Family level. I suggest that ongoing biodiversity assessments and future ecological work in temperate forests should include canopy sampling, as omitting it might lead to an inaccurate representation of forest systems. Forest management should also be limited in frequency (time-since harvest) and intensity (silvicultural techniques), since canopy closure seems to be an important factor in shaping arthropod communities.

This book was released on 2017 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bark and wood boring beetles include some of the most economically important forest insects, especially those that are introduced to novel environments. A proper understanding of species distribution is critical for detection and management. In this study we placed traps at three heights above ground at the edge and on the interior of two forests targeting two beetle guilds: wood/phloem feeding beetles and ambrosia beetles. We recorded temperature, humidity, and canopy cover for each trap. We found species richness to increase with height for wood/phloem feeding beetles and decrease with height for ambrosia beetles. We also found the combination of height and placement to significantly affect abundance for both guilds. Our results indicate that to capture the full diversity of these guilds, traps must be placed at multiple heights and at both the edge and interior of forests.
Download or read book Saproxylic Insects written by Michael D. Ulyshen and published by Springer. This book was released on 2018-05-21 with total page 896 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers extensive information on insect life in dying and dead wood. Written and reviewed by leading experts from around the world, the twenty-five chapters included here provide the most global coverage possible and specifically address less-studied taxa and topics. An overarching goal of this work is to unite literature that has become fragmented along taxonomic and geographic lines. A particular effort was made to recognize the dominant roles that social insects (e.g., termites, ants and passalid beetles) play in saproxylic assemblages in many parts of the world without overlooking the non-social members of these communities. The book is divided into four parts: · Part I “Diversity” includes chapters addressing the major orders of saproxylic insects (Coleoptera, Diptera, Hymenoptera, Hemiptera, Lepidoptera and Blattodea), broadly organized in decreasing order of estimated global saproxylic diversity. In addition to order-level treatments, some chapters in this part discuss groups of particular interest, including pollinators, hymenopteran parasitoids, ants, stag and passalid beetles, and wood-feeding termites. · Part II “Ecology” discusses insect-fungal and insect-insect interactions, nutritional ecology, dispersal, seasonality, and vertical stratification. · Part III “Conservation” focuses on the importance of primary forests for saproxylic insects, offers recommendations for conserving these organisms in managed forests, discusses the relationships between saproxylic insects and fire, and addresses the value of tree hollows and highly-decomposed wood for saproxylic insects. Utilization of non-native wood by saproxylic insects and the suitability of urban environments for these organisms are also covered. · Lastly, Part IV “Methodological Advancements” highlights molecular tools for assessing saproxylic diversity. The book offers an accessible and insightful resource for natural historians of all kinds and will especially appeal to entomologists, ecologists, conservationists and foresters.

Download or read book Forests and Insect Conservation in Australia written by Tim R. New and published by Springer. This book was released on 2018-08-27 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Losses of forests and their insect inhabitants are a major global conservation concern, spanning tropical and temperate forest regions throughout the world. This broad overview of Australian forest insect conservation draws on studies from many places to demonstrate the diversity and vulnerability of forest insects and how their conservation may be pursued through combinations of increased understanding, forest protection and silvicultural management in both natural and plantation forests. The relatively recent history of severe human disturbance to Australian forests ensures that reasonably natural forest patches remain and serve as ‘models’ for many forest categories. They are also refuges for many forest biota extirpated from the wider landscapes as forests are lost, and merit strenuous protection from further changes, and wider efforts to promote connectivity between otherwise isolated remnant patches. In parallel, the recent attention to improving forest insect conservation in harmony with insect pest management continues to benefit from perspectives generated from better-documented faunas elsewhere. Lessons from the northern hemisphere, in particular, have led to revelations of the ecological importance and vulnerability of many insect taxa in forests, together with clear evidence that ‘conservation can work’ in concert with wider forest uses. A brief outline of the variety of Australian tropical and temperate forests and woodlands, and of the multitude of endemic and, often, highly localised insects that depend on them highlights needs for conservation (both of single focal species and wider forest-dependent radiations and assemblages). The ways in which insects contribute to sustained ecological integrity of these complex ecosystems provide numerous opportunities for practical conservation.

Download or read book Boundary Dynamics and Matrix Effects on Beetle Community Composition and Movement Between Forests and Agriculture written by Sarah Kathleen Dudziak and published by . This book was released on 2007 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect movement across habitat edges between forest and agriculture has the potential to affect ecosystem processes. In this study, I quantified aerial beetle communities in Ohio along transect lines crossing forest edges and stretching into corn and forest habitats. The goal of this study was to determine the effect of forest patch size, distance to the forest edge and agricultural matrix effects on beetle community dynamics. Beetle abundance and species richness were significantly higher at the edge throughout season. Net difference in abundance showed that in large fragments, individuals moved toward forest interior whereas beetles in small fragments flux towards corn. This suggests that large forest fragment edge were "hard" compared to small forest fragments. Non-metric Multidimensional Scaling showed log patch area and tree importance value were the two most importance variables in determining species composition. Spillover of insects across boundaries has various implications for biodiversity research in land management.
Download or read book Tropical Forest Canopies Ecology and Management written by K.E. Linsenmair and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Almost half of all life on earth may exist in the world's forest canopies. They may also play a vital role in maintaining the planet's climate, yet they remain largely unexplored owing to difficulties of access. They are renowned for their great diversity and role in forest functioning, yet there are still great gaps in the understanding of this `last biological frontier'. This seminal book shows how canopy science is now in a position to answer many of the outstanding questions, among which are some of the most pressing environmental issues society is presently facing. It represents a major summary of the current understanding of canopy ecology, and maps a path forward into a greater understanding of tropical forest ecology and management at a time when the very future of this ecosystem is threatened by humanity's actions.
Download or read book Arthropods of Tropical Forests written by Yves Basset and published by Cambridge University Press. This book was released on 2003-01-23 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are the most diverse group of organisms on our planet and the tropical rainforests represent the most biologically diverse of all ecosystems. This book, written by 79 authors contributing to 35 chapters, aims to provide an overview of data collected during recent studies in Australia, Africa, Asia, and South America. The book focuses on the distribution of arthropods and their use of resources in the rainforest canopies, providing a basis for comparison between the forest ecosystems of the main biogeographical regions. Topics covered include the distribution of arthropods along vertical gradients and the relationship between the soil/litter habitat and the forest canopy. The temporal dynamics of arthropod communities, habitats and food selection are examined within and among tropical tree crowns, as are the effects of forest disturbance. This important book is a valuable addition to the literature used by community ecologists, conservation biologists entomologists, botanists and forestry experts.
Download or read book Insect Conservation written by Michael J Samways and published by CABI. This book was released on 2019-12-02 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects do not live in isolation. They interact with the abiotic environment and are major components of the terrestrial and freshwater biotic milieus. They are crucial to so many ecosystem processes and are the warp and weft of all terrestrial and freshwater ecosystems that are not permanently frozen. This means that insect conservation is a two-way process: insects as the subjects of conservation, while also they are useful tools for conserving the environment. This book overviews strategic ways forward for insect conservation. It is a general view of what has worked and what has not for the maintenance of insect diversity across the world, as well as what might be the right approaches for the future.

This book was released on 2017-03-21 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new approach to insect modeling discusses population dynamics' regularities, control theory, theory of transitions, and describes methods of population dynamics and outbreaks modeling for forest phyllophagous insects and their effects on global climate change. Research in insect population dynamics is important for more reasons than just protecting forest communities. Insect populations are among the main ecological units included in the analysis of stability of ecological systems. Moreover, it is convenient to test new methods of analyzing population and community stability on the insect-related data, as by now ecologists and entomologists have accumulated large amounts of such data. In this book, the authors analyze population dynamics of quite a narrow group of insects – forest defoliators. It is hoped that the methods proposed herein for the analysis of population dynamics of these species may be useful and effective for analyzing population dynamics of other animal species and their effects and role in global warming. What can insects tell us about our environment and our ever-changing climate? It is through studies like this one that these important answers can be obtained, along with data on the insects and their behaviors themselves. The authors present new theories on modeling and data accumulation, using cutting-edge processes never before published for such a wide audience. This volume presents the state-of-the-art in the science, and it is an essential piece of any entomologist's and forest engineer's library.

Download or read book Treetops at Risk written by Margaret Lowman and published by Springer Science & Business Media. This book was released on 2013-06-22 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest canopies not only support high terrestrial biodiversity but also represent a critical interface between the atmosphere and the earth. They provide goods and services to support diverse human communities and offer opportunities to explore sustainable use of these resources for many generations of local livelihoods. Forest canopies are important carbon sequestration units, and in this sense, serve as climate control for the planet. Canopies are important energy production centers for the planet, and serve as the basis for many food chains. The canopy can also act as a hook for education outreach and conservation, inspiring ecotourism through recreation and other sustainable uses such as treetop walks, zip lines, and birding. Despite these critical services provided by forest canopies, almost no dedicated research in the treetops was initiated until as recently as the late 1970s when single rope techniques were developed by mountaineering professionals and adapted for use in the canopy. Subsequently, an array of canopy access tools was designed in the 1980s and early 1990s that have opened up this “eighth continent” for global exploration and discovery. This volume uses the major findings of the 5th international canopy conference as a platform for organization, but it does not mimic the sessions and presentations of the conference itself. Instead, it builds on the important themes that emerged from the conference and solicits articles that represent future priorities and advancements for canopy science in the next decade. Despite the global efforts of hundreds of forest scientists over the past 3 decades, forests are degrading at an accelerated rate and biodiversity is increasingly threatened by human activities. Given these trends - despite the very best efforts of the world’s best scientists - other approaches must be taken. This volume summarizes the issue of “treetops at risk” and assembles a global authorship to examine past accomplishments and future initiatives critical in forest conservation.
