This book was released on 2013 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of diversity and species distributions are crucial in light of a predicted 4-6°C warming by the end of the 21st century, especially in the tropics where many species may be especially sensitive to climate change. Little is known about patterns of insect diversity and richness in Andean montane forest habitats. The main goal of the present research was to investigate the ecology of carabid beetles at different altitudes in southeastern Peru (Coleoptera: Carabidae). Changes in species richness, species assemblages, and wing and body attributes were estimated at different altitude zones along both disturbed and undisturbed gradients. My first objective was to estimate species richness patterns of carabid beetles on Andean slopes. Preliminary collections employed both hand collections and pitfall traps, but I found that hand collections were more efficient; subsequent data collection was carried out by hand collections. Preliminary data collected on an anthropogenically disturbed gradient from 1400 m to 3450 m revealed a decline in raw species number with altitude. When species number was adjusted for sample size (rarefaction) this trend produced a middle altitude peak in species richness. A truncated portion of the disturbed gradient (2000 m to 3450 m) was also compared to a parallel, old growth gradient, and no pattern was found with altitude for either gradient. However, overall species richness was lower for assemblages from the disturbed gradient. Species assemblages varied by altitude and by whether anthropogenic disturbance had occurred. The second objective was to characterize changes in body length and dispersal ability with altitude. For both morphological attributes, altitudinal patterns were highly variable among tribes of carabid beetles, exhibiting positive, negative and no correlation with altitude. When carabid beetle taxa were combined, however, body length and incidence of flightlessness were both significantly negatively correlated with altitude. Observation of morphological characters between the two gradients revealed that carabid beetles on an anthropogenically disturbed habitat were longer and had greater dispersal ability than those on an old growth gradient. The third objective was to compare assemblages of carabid beetles in the Andes of Peru to a temperate counterpart in the southern Appalachian Mountains, USA. Species richness of carabid beetle assemblages was found to be approximately twice as high in the Andean assemblage. Both assemblages showed a middle altitude peak in species richness. Furthermore, species composition of carabid assemblages had no overlap at the species and genus level, but species composition in both the Andes and the Appalachians varied with altitude. Body length was greater and dispersal ability was reduced for Appalachian as compared to Andean assemblages. Both regions exhibited similar patterns in body length in relation to altitude. However, while the proportion of flightless species was positively correlated with increasing altitude in the Andes, more than 90% of the species in the Appalachians were flightless at all elevations. I suggest the altitude-species richness trend may be more conclusive when a more complete altitudinal gradient is sampled, i.e., extending sampling along the entire length of the gradient. Furthermore, employing multiple study transects will enhance statistical validity of the results and greatly increase our knowledge of how carabid beetle assemblages vary along tropical altitudinal gradients.

Book excerpt: The family Carabidae (ground-beetles, including tiger beetles) is composed of over 34,000 species distributed among 1,927 genera worldwide. Carabids occupy most land habitats on nearly all continents. Most ground-beetles, in temperate climates at least, live at the surface of the ground, while some species dwell in the soil, in caves, or on vegetation. They are mostly active at night and prey on a wide range of small animals such as other insects and spiders; some species are active during the day and feed on plant tissue. Most are recognisable alive by a peculiar way of running on the ground. Compared with larger or warmer regions of the world, the New Zealand fauna may appear relatively small, but New Zealand is a biodiversity 'hot-spot' with over fifty genera (about 60% of fauna) found nowhere else in the world. As a family, Carabidae are sensitive to their environment and are commonly used as biological indicators. They can also be used to control pest insects (e.g., caterpillars) and in the future, ground-beetles may become more commonly used in biological control.In New Zealand, conservation biologists have listed many, often large-sized carabids, as rare or threatened and worthy of protection. This new Fauna of New Zealand contribution partly updates Larochelle & Lariviere's Catalogue (FNZ 43) of 2001. Aimed at specialists and non-specialists, it should greatly facilitate identification and information gathering. Its purpose is to provide an overview of 134 species and subspecies belonging to the tribes Cicindelini, Pamborini, Amarotypini, Migadopini, Clivinini, Moriomorphini, and Trechini. Habitus colour photos and distribution maps are included for all taxa. Two genera and 16 species are described as new.

Book excerpt: Arthropods have received considerable attention as biological indicators (bioindicators) as they are widespread, and easy to sample. Due to a shortage of trained taxonomists and limited resources, many taxa cannot be used, however. In this thesis, I use carabid beetles (Coleoptera: Carabidae), which are taxonomically well known, to compare three approaches of bioindication, using a traditional taxonomic approach as the baseline. The taxonomic approach distinguished coarse differences in forest canopy removal, as did a recognizable taxonomic unit approach. The latter failed to provide the same level of precision based on diversity data, however. A functional trait approach yielded non-significant results, but demonstrated potential to provide more in-depth information, albeit at a considerable additional investment of time. All three approaches were found to have advantages and disadvantages, so I conclude that the choice of approach will depend on the availability of resources and the objectives of each bioindication study. --P.ii.

Available in PDF, EPUB and Kindle. Book excerpt: This volume presents an overview of current accomplishments and future directions in ecological theory. The twenty-three chapters cover a broad range of important topics, from the physiology and behavior of individuals or groups of organisms, through population dynamics and community structure, to the ecology of ecosystems and the geochemical cycles of the entire biosphere. The authors focus on ways in which theory, whether expressed mathematically or verbally, can contribute to defining and solving fundamental problems in ecology. A second aim is to highlight areas where dialogue between theorists and empiricists is likely to be especially rewarding. The authors are R. M. Anderson, C. W. Clark, M. L. Cody, J. E. Cohen, P. R. Ehrlich, M. W. Feldman, M. E. Gilpin, L. J. Gross, M. P. Hassell, H. S. Horn, P. Kareiva, M.A.R. Koehl, S. A. Levin, R. M. May, L. D. Mueller, R. V. O'Neill, S. W. Pacala, S. L. Pimm, T. M.

Download or read book Beetles written by Camilla Stack and published by Nova Science Publishers. This book was released on 2014-01-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beetle species belonging to the coleopteran families Bruchidae, Curculionidae, Laemophoeidae, Silvanidae and Tenebrionidae, as well as beetle-like insects from the psocopteran family Liposcelidae, are responsible for serious damages to agricultural products and resources. These beetles can be primary and/or secondary pests, feeding on integral and healthy grains or attacking those already damaged. The affected grains lose weight and germination power, have nutritive value and vigor decreased, as well as have the hygiene and sanity conditions impaired. This book examines the biodiversity, ecology and role in the environment of beetles.
Download or read book Carabid Beetles Ecology and Evolution written by K. Desender and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Carabidae form one of the largest and best studied families of insects, occurring in nearly every terrestrial habitat. The contributions included in this book cover a broad spectrum of recent research into this beetle family, with an emphasis on various aspects of ecology and evolution. They deal both with individual carabid species, for example in studies on population and reproductive biology or life history in general, and with ground beetle communities, as exemplified in papers treating assemblages in natural habitats, on agricultural land and in forests. Disciplines range from biogeography and faunistics, over morphology, taxonomy and phylogenetics, ecophysiology and functional ecology, to population, community, conservation and landscape ecology. This volume is the result of the 8th European Carabidologists' Meeting, 2nd International Symposium of Carabidology, September 1-4, 1992, Belgium.

Available in PDF, EPUB and Kindle. Book excerpt: With the increasing numbers of research workers and groups of investigators devoting themselves to the ecology of carabids I felt that the time had come to take stock of the existing knowledge in this field and to endeavour to weld my personal results and those of other workers into a comprehensive picture. It was with these aims in mind that the following study was conceived. A further goal was to attempt to show to what extent research on carabids can contribute to the larger fields of research encompassing ecology, ethology and evolution. In my opinion the investigations on carabids permit us to draw conclusions of general applicability and, as such, comparable with those made in recent years upon other groups of animals. I am well aware of the risk involved nowadays in attempting, on one's own, to integrate results from a wide variety of scientific disciplines into a meaningful whole, and for this reason I am always grateful for corrections and for additional information. It is impossible for me to mention by name all of the col leagues who have given me their support in the preparation of the book. Reprints of their publications have been placed at my disposal by almost all of the authors cited, as well as by others whose names and works have been omitted merely in order to prevent the book from taking on encyclopedic pro portions. I am nevertheless indebted to them all for their cooperation.

Download or read book High Altitude Primates written by Nanda B. Grow and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic goal of the volume is to compile the most up to date research on how high altitude affects the behavior, ecology, evolution and conservation status of primates, especially in comparison to lowland populations. Historically, the majority of primate studies have focused on lowland populations. However, as the lowlands have been disappearing, more and more primatologists have begun studying populations located in higher altitudes. High altitude populations are important not only because of their uniqueness, but also because they highlight the range of primate adaptability and the complex variables that are involved in primate evolution. These populations are good examples of how geographic scales result in diversification and/or speciation. Yet, there have been very few papers addressing how this high altitude environment affects the behavior, ecology, and conservation status of these primates.

Available in PDF, EPUB and Kindle. Book excerpt: Climate change has been a central concern over recent years, with visible and highly publicized consequences such as melting Arctic ice and mountain glaciers, rising sea levels, and the submersion of low-lying coastal areas during mid-latitude and tropical cyclones. This book presents a review of the spatial impacts of contemporary climate change, with a focus on a systematic, multi-scalar approach. Beyond the facts – rises in temperature, changes in the spatial distribution of precipitation, melting of the marine and terrestrial cryosphere, changes in hydrological regimes at high and medium latitudes, etc. – it also analyzes the geopolitical consequences in the Arctic and Central Asia, changes to Mediterranean culture and to viticulture on a global scale, as well as impacts on the distribution of life, for example, in the Amazon rainforest, in large biomes on a global scale, and for birds.
