Problems of insect enumeration and assessment of needs are addressed in the contexts of rapid and substantial losses and changes to all key Australian terrestrial and freshwater environments and promoting awarenesss of the importance of insects. Further definition of the insect fauna and its peculiarities can aid threat alleviation and practical management to protect and conserve this unique and largely endemic biodiversity. Written for the many environmental managers and naturalists who are not primarily entomologists, the ten chapters expand from considerations of insect decline and diversity to the unique features of the Australian fauna and its characterisation. Cases and examples from throughout the world illustrate the major needs, approaches and priorities to sustaining a poorly known, diverse and ecologically varied insect heritage of global significance.

Global change poses increasing threats to ecological communities and ecosystem functioning. To improve our understanding of how arthropod communities, and associated ecosystem functions respond to combined impacts of future climate change and land-use intensification in grassland ecosystems, I used the experimental set-up of the Global Change Experimental Facility (GCEF). In my first chapter, I studied the combined effects of climate change and land-use intensity on arthropod community composition at the whole community level and of four trophic groups (predators, herbivores, detritivores and omnivores). I found that climate change and land-use intensification simultaneously shift species composition across trophic levels, through changes in abundance, species richness, and evenness. In my second chapter, I present a comprehensive set of linear regressions to estimate live body mass using data on body length and width, taxonomy and geographic origin. Furthermore, I quantified prediction discrepancy when using parameters from arthropods of a different geographic region. Incorporating body width into taxon- and region-specific length-mass regressions substantially increased prediction accuracy for live body mass. In my third research chapter, I studied the impacts of future climate change and land-use intensification on ecosystem functioning and the stability of arthropod food-webs. I furthermore studied the response of underlying community characteristics driving these ecosystem processes. Specifically, I tested the response of mean body mass, biomass and community metabolism of the whole community and four trophic groups to climate change and land-use intensification. Despite changes in community characteristics of the trophic groups, community ecosystem processes and food-web stability remained stable under climate change and land-use intensification, while the composition of total ecosystem processes changed.

Arctic ecosystems are undergoing rapid change. Terrestrial arctic arthropods (insects, spiders and others) are not only appreciably diverse, but also sensitive to their environment. As such, tundra arthropod communities and food webs could provide critical insight into the ecological consequences of global change in the Arctic. My dissertation examined the underpinnings of arthropod community and food web dynamics in arctic tundra. First, I explored how changes to plant production and plant community composition affect arthropod community composition, trophic structure and food web function. I also explored one key trophic interaction: cannibalism among wolf spiders, the most abundant terrestrial predator in most arctic systems. Last, I examined the effects of plant communities and weather on arthropod phenology and activity, key determinants of the rate and role of arthropod-mediated food web processes like predation, decomposition and pollination. Overall, my research reveals that arctic consumers are strongly limited by food availability well as weather conditions in the Arctic. Early springs, warmer temperatures, increased plant production and greater shrub dominance - key consequences of arctic global change-will affect the composition of arthropod communities and the ecological functions they perform.

Insect Ecology: An Ecosystem Approach, Fourth Edition, follows a hierarchical organization that begins with relatively easy-to-understand chapters on adaptive responses of insect populations to various environmental changes, disturbances, and anthropogenic activities, how insects find food and habitat resources, and how insects allocate available energy and nutrients. Chapters build on fundamental information to show how insect populations respond to changing environmental conditions, including spatial and temporal distribution of food and habitat. The next section integrates populations of interacting species within communities and how these interactions determine structure of communities over time and space. Other works in insect ecology stop there, essentially limiting presentation of insect ecology to evolutionary responses of insects to their environment, including the activities of other species. The unique aspect of this book is its four chapters on ecosystem structure and function, and how herbivores, pollinators, seed predators, and detritivores drive ecosystem dynamics and contribute to ecosystem stability. Provides the most advanced synthesis of insect ecology, with updated material throughout and new chapters Presents the roles of insects in delivery of ecosystem services and applications to pest management and conservation Features full coverage of ecosystem structure and function balanced with essential background on evolutionary aspects Includes case studies highlighting practical and theoretical applications for topics covered in each chapter

Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.
