This AIDGAP identification guide covers all the species of earthworms found living freely in the UK and Ireland. Since publication of the First Edition in 2012, there has been an explosion of interest in earthworms, with many more people actively recording earthworms and submitting records to the National Scheme. The Second Edition is twice as long as the First Edition and includes several new features: Extra key to earthworms found in artificial environments (such as heated greenhouses); New guidance on earthworm dissection and internal anatomy; Expanded introductory section on earthworm ecology and biology; Many new photographs within the Species Accounts taken especially for this guide, including lots of live specimens; New line drawings of the tubercula pubertatis for all species where this character is present; and Updates to distribution and status information for each species in the light of new data.

Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms’ innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.

Earthworms are not native to the Great Lakes Region. They were all wiped out after the last glaciation. The current population, brought here by early Europeans, is slowly changing the face of our native forests.

As a result of the European Commission’s concern for the status of continental waters, and as a clear reflection of the notion of water as heritage to be conserved, in the year 2000 the Water Framework Directive (2000/60/CE) was enacted, its goal being to establish a framework to protect water and the different aquatic ecosystems by requiring the Member States to achieve a good ecological status in all their waters by 2015. Like all ecosystems, freshwater ecosystems undergo physical, chemical and energy-related changes, both of natural and anthropogenic origin. These disturbances affect the organisms living in them and those who utilize their resources. Therefore, evaluating these changes has become a very important task in order to better understand aquatic systems. The study and analysis of the ecological status of these ecosystems in relation to their conservation status and water quality is thus a fundamental tool for a more efficient and rational management of their resources, that is, a management that does not threaten the ecosystem. The present guide for the identification of Spanish freshwater macroinvertebrates aims to facilitate the job of those who go to great lengths to identify them in order to then determine biotic indices. It is not the aim of this book to serve as a zoological treaty, nor does it claim to add new information on the biology or the ecology of the taxa covered. This book is, simply, a working tool explicitly designed to facilitate the identification of the Spanish macroinvertebrates and the subsequent computing of biotic indices.
