This book brings together a wide range of sampling methods for investigating different arthropod groups. Each chapter is organized to describe and evaluate the main sampling methods (field methods, materials and supplies, sampling protocols, effort needed, and limitations); in addition, some chapters describe the specimen preparation and conservation, species identification, data collection and management (treatment, statistical analysis, interpretation), and ecological/conservation implications of arthropod communities. The book aims to be a reference for zoologists, entomologists, arachnologists, ecologists, students, researchers, and for those interested in arthropod science and biodiversity. We hope the book will contribute to advance knowledge on field assessments and conservation strategies. Arthropods represent the most speciose group of organisms on Earth, with a remarkable number of species and interactions still to be described. These invertebrates are recognized for playing key ecological roles in terrestrial, freshwater and marine ecosystems. Because of the increasing and relentless threats arthropods are facing lately due to a multitude of human induced drivers, this book represents an important contribution to assess their biodiversity and role in ecosystem functioning and generation of ecosystem services worldwide.

The book brings to light the most recent findings on the biogeography, biodiversity, host plant induction and natural history of gall inducing insects in the Neotropical region.We attempt to summarize the work done so far in the region, promote several syntheses on many aspects such as host induction, host specialization, distribution among the several vegetation types and zones, the origin of super hosts and the mechanisms leading to geographical patterns in their distribution.Furthermore, the book constructs new perspectives for deeper understanding of galling insect evolutionary ecology and biogeopgraphy in the region."
