Book excerpt: The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Available in PDF, EPUB and Kindle. Book excerpt: Now that more than half of the world’s population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world’s expanding metropolises.

Download or read book The Impact of Non native Plants on Bird Communities in Suburban Forest Fragments written by Amanda Conover and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest fragmentation has occurred across the Eastern United States, and an ecological effect linked to fragmentation is the invasion of non-native plants into forests. Few studies have examined the link between the density of native plants and avian habitat use in forest fragments. The objective of this project was to estimate the relationship between occupancy of eight songbird species and native plant density, forest structure, and invertebrate biomass. We collected data at ninety-eight 25 m radius forested plots in Delaware and Maryland. Avian point counts were conducted 3 times per season between 15 May-7 August, 2009-2010. Vegetation was analyzed by measuring understory coverage, canopy coverage, basal area, and proportion of native plants. Invertebrate biomass was measured by vacuum sampling. We used program PRESENCE to build occupancy models with invertebrate biomass and vegetation characteristics as covariates to explain candidate bird species presence, and evaluated the models using Akaike Information Criterion. The proportion of native plants was the best variable in predicting Wood Thrush occupancy. Forest structure variables were the strongest predictors of presence for American Robin, Carolina Chickadee, and Gray Catbird. Both forest structure and native plant proportion were important variables in predicting the occupancy of Eastern Towhee, Northern Cardinal, and Ovenbird. For Carolina Wren, invertebrate abundance was the most important variable in predicting occupancy. My results suggest that native plant proportion and vegetation structure may both be important factors to consider in conservation planning and habitat restoration for these songbirds.

Download or read book Ecology and Conservation of Birds in Urban Environments written by Enrique Murgui and published by Springer. This book was released on 2017-02-10 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides syntheses of ecological theories and overarching patterns of urban bird ecology that have only recently become available. The numerous habitats represented in this book ranges from rows of trees in wooded alleys, to wastelands and remnants of natural habitats encapsulated in the urban matrix. Authored by leading scientists in this emergent field, the chapters explore how the characteristics of the habitat in urban environments influence bird communities and populations at multiple levels of ecological organization and at different spatial and temporal scales, and how this information should be incorporated in urban planning to achieve an effective conservation of bird fauna in urban environments. Birds are among the most conspicuous and fascinating residents of urban neighborhoods and provide urban citizens with everyday wildlife contact all over the world. However, present urbanization trends are rapidly depleting their habitats, and thus knowledge of urban bird ecology is urgently needed if birds are to thrive in cities. The book is unique in its inclusion of examples from all continents (except Antarctica) in an effort to arrive at a more holistic perspective. Among other issues, the individual chapters address the censusing of birds in urban green spaces; the relationship between bird communities and the structure of urban green spaces; the role of exotic plant species as food sources for urban bird fauna; the influence of artificial light and pollutants on bird fauna; trends in long-term urban bird research, and transdisciplinary studies on bird sounds and their effects on humans. Several chapters investigate how our current knowledge of the ecology of urban bird fauna should be applied in order to achieve better management of urban habitats so as to achieve conservation of species or even increase species diversity. The book also provides a forward-looking summary on potential research directions. As such, it provides a valuable resource for urban ecologists, urban ecology students, landscape architects, city planners, decision makers and anyone with an interest in urban ornithology and bird conservation. Moreover, it provides a comprehensive overview for researchers in the fields of ecology and conservation of urban bird fauna.

Download or read book The Effects of Urbanization on the Ecology of Bird Communities in Los Angeles written by Jeffrey Ga-Ho Lee and published by . This book was released on 2016 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization, characterized by the rapid growth of human development and resource consumption, not only replaces preexisting habitats but can also convert entire landscapes and their associated ecological services. As a result, these areas provide researchers with opportunities to study how wildlife species respond to novel habitat scenarios. In Chapter 1, we directly compared the House Sparrow's (Passer domesticus) success among different habitat typologies in its native and non-native distributions. We related their numbers to environmental variables describing vegetation structure, urban infrastructure, and human activity. Our results are not only consistent with previous reports but also reveal some useful insights for the development of population management tools. In Chapter 2, we assessed the feasibility of using Google Street View as an ecological tool for gathering environmental data in different urban areas and typologies. Our results provide an optimistic look for GSV's utilization as a powerful tool in the field of ecology.

Download or read book Ecology and Conservation of Forest Birds written by Grzegorz Mikusiński and published by Cambridge University Press. This book was released on 2018-03-29 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.

Book excerpt: Human modification of the environment rapidly alters ecological processes and the composition of plant and animal communities. Understanding the impacts of such anthropogenic disturbances are needed to predict future biotic conditions, inform land management practices, and conserve biological diversity. This dissertation aimed to generate original scientific research on anthropogenic disturbance ecology and present those findings to a broad audience. I had five specific objectives and associated findings. First, to assess over a decade of landscape change (1998-2010) occurring in the Puget Lowlands of Washington state, where exurban areas are converting from forest to either low-density conservation development (CD) or higher density planned community development (PCD). Second, to test predictions of successional change (stability, heterogeneity, and diversity) in structuring local bird communities of these emerging suburbs. Third, to quantify abundance of birds in each form of development by both tolerance of human activity (synanthropic guilds) and individual species persistence. Fourth, to extend the reach of informal education by designing a public science exhibition format. Fifth, to communicate suburban-bird ecology to a broader literary audience through original illustrations. Applying object-oriented image assessment (OBIA) and compositional analyses to available orthophotography, I found the rate of land conversion, amount of built cover, and forest loss positively correlated with housing density. However, habitat fragmentation (total edge) increased equally in CDs and PCDs. As predicted by classical succession, bird communities following disturbance became more stable over time, less heterogeneous, and grew in diversity. However, CDs stabilized more quickly and remained more heterogeneous than PCDs. CDs retained more native forest birds (avoiders), excluded more synanthropic (exploiter) species, and hosted similar numbers of early successional (adaptor) species relative to PCDs; however, a few highly abundant species dominated each guild. I propose the Living Science Journal (LSJ), an interactive museum-style exhibition format to feature peer-reviewed ecological studies for informal public education. Finally, I created 41original natural science illustrations to accompany the book Welcome to Subirdia: Sharing our neighborhoods with wrens, robins, woodpeckers, and other wildlife, authored by my doctoral advisor, Professor John Marzluff.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Parks of the mid-Atlantic are under constant human pressure from the surrounding urban / suburban matrix. With accelerated development over the past 20 years and population increases predicted during the next 20 years, these National Parks are increasingly critical habitat for forest breeding birds. The assessment of bird community integrity is an important first step in the management of these conservation areas. To this end, I applied previously developed bird community indices (BCIs) to National Park Service avian Inventory and Monitoring Program data. This technique uses proportional species representation across a suite of avian guilds with specialist guilds ranked more favorably than generalist guilds. Each monitoring location was scored based on the bird species detected, which can then be summed to produce a final BCI score for a suite of locations, a park or a region. I estimated and analyzed patch and landscape scale habitat variables to determine how these variables influenced the BCI score at each of the 385 avian monitoring locations across 11 National Parks, and two physiographic regions. The National Parks of the Piedmont/Coastal Plain region had greater BCI scores than the parks in the Appalachian region (P
