Arctic and Subarctic North America is particularly affected by climate change, where average temperatures are rising three times faster than the global average. Documenting the changing climate/environment of the north requires a structured knowledge of indicator taxa that reflect the effects of climate changes.Aleocharine beetles are a dominant group of forest insects, which are being used in many projects as indicators of environmental change. Many species are forest specialists restricted to certain microhabitats, some are generalists and others are open habitat specialists. They represent many ecological niches and, as such, are good indicators for many other species as well. The majority of Canadian aleocharine beetle species (about 600 spp.) has been studied and published by Jan Klimaszewski et al. (2018, 2020), mainly from southern, central, and western Canada, while the northern taxa remain poorly known and documented. The aim of the present book is to summarize the knowledge on this insect group in the Arctic and Subarctic North America and to provide a diagnostic and ecological tool for scientists studying and monitoring insects in northern Canada and Alaska. The book includes a review of the literature, information on 238 species and their habitats, taxonomic review, images, and identification tools.

This handbook presents a comprehensive overview of insect conservation and provides practical solutions to counteract insect declines, at a time where insects are facing serious threats across the world from habitat destruction to invasive species and climate change. The Routledge Handbook of Insect Conservation consist of six sections, covering all aspects of insect conservation, containing contributions from academics, researchers and practitioners from across the globe. Section I addresses the fundamentals of insect conservation and outlines the reason why insects are important and discusses the greatest drivers of insect decline. The chapters in Section II examine the approaches that can be used for insect conservation globally, such as protected areas and agroecology, while highlighting the importance of insects in the composition and function of ecosystems. The chapters in Section III focus on insect populations in the major biomes around the world, from temperate and tropical forests to savannas and grasslands, with the chapters in Section IV focusing on natural and manmade ecosystems of the world, including mountain, soil, urban, island and agricultural habitats. They discuss the unique pressures and challenges for each biome and ecosystem and offer practical solutions for conserving their insect populations. Section V focuses on the assessment and monitoring of insects for conservation, discussing how we can implement practical monitoring protocols and what options are available. A wide variety of methods and tools are examined, including citizen science, bioindication, the role of taxonomy, drones and eDNA. The book concludes by examining policy and education strategies for insect conservation in Section VI. The chapters discuss key issues around social and policy strategies and conservation legislation for ensuring the long-term protection of insects. This book is essential reading for students and scholars of biodiversity conservation and entomology as well as professionals and policymakers involved in conservation looking for real-world solutions to the threats facing insects across the globe.

Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research examples in the fields of phylogeny and systematics, ecology and conservation, and reproduction and development. The combination of review chapters and case studies provides an excellent introduction to the biology of rove beetles and enables readers to become familiar with active research fields in this megadiverse group of beetles. Offering easy access to these fields, it also demonstrates how staphylinids are used as bioindicators in applied ecosystem research, including that concerning conservation issues. Experienced scientists and beginners alike find the diversity of subjects covered intriguing and inspiring for continuing and starting their own research. The book is intended for students and researchers in biology and zoology (entomology), including morphologists, ecologists, soil scientists, evolutionary biologists, paleontologists, biogeographers, taxonomists and systematists.

A first comprehensive synopsis of all aleocharine rove beetle species (Coleoptera, Staphylinidae) recorded from eastern Canada, from Ontario to the Maritime Provinces inclusively, is presented. Four hundred and seven species in 96 genera, and 16 tribes are presented and discussed.Tribes and subtribes are arranged in presumably phylogenetic order as it is currently recognized. Genera and subgenera are listed alphabetically. Species are listed alphabetically or in species groups to better reflect their relationships. Species distribution is listed by abbreviated provinces and territories in Canada and abbreviated states in the United States. Geographic status is given to every species as Native, Holarctic or adventive with some species listed with undetermined status - adventive or Holarctic. Every treated species is presented with a diagnosis, including short description of body and description of the median lobe of aedeagus, spermatheca, and tergite and sternite VIII of both sexes. For each species a plate with colour habitus image and black and white images of genital structures is provided to aid with positive identification. Collection and habitat data (often new) are presented for each species, including data on macrohabitat, microhabitat, collecting period, and collecting methods.

This insightful Handbook scrutinizes alternative concepts and approaches to the dominant economic or industrial theories of innovation. Providing an assessment of these alternatives, it questions the absence of these neglected types of innovation and suggests diverse theories.

This authoritative reference provides an engaging look at these magnificent yet poorly understood creatures and highlights the essential role beetles play in the dynamics of nearly every terrestrial ecosystem on Earth. Color photos.
