Download or read book Ecology and conservation of the Dutch ground beetle fauna written by Hans Turin and published by BRILL. This book was released on 2023-09-14 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decades, large amounts of data about carabids have been collected in the Netherlands, initially for the purpose of creating distribution maps for the country. In addition to information from collections and faunistic publications, a significant amount of data came from ecological studies using pitfall traps. Because of the rich tradition of carabidological research in the Netherlands, an exceptionally large database of these pitfall data is available. The database is a mix of approximately 1,500 short-term samples and circa 4,400 so-called 'year-samples', for which pitfalls were functional during the whole activity period of ground beetles in spring and autumn. These year-samples came from 2,850 sites, covering the period of 1953-2018, and represent all habitats on the Dutch landscape. These data offer an unusual view of the presence and activity of this common insect family. The data gathered from pitfall trapping is summarised and provides a fresh integrated perspective about the Dutch ground beetle fauna. The characteristic species composition of 17 habitat groups is described in detail. Over 320 species present in the database have been classified into six main groups, according to their patterns of habitat use. Both the classification of habitats and associated species have been tested and used in various analyses in the book. Two chapters give special attention to changes in the Dutch fauna over the past 66 years by means of extensive trend analysis and relate this understanding to nature conservation. The book provides an extension and update for Turin's (2000) atlas. The Dutch carabid fauna is discussed considering relevant literature but uses predominantly European studies to put the faunal patterns in broader context. This book presents the story of Dutch ground beetles and illustrates the contribution of pitfall trapping to our understanding of the ecology of this fascinating and unusually well-studied group of beetles.

Book excerpt: This textbook offers a detailed overview of the current state of knowledge concerning the ecology and management of compositionally and structurally diverse forests. It provides answers to central questions such as: What are the scientific concepts used to assess the growth, dynamics and functioning of mixed-species forests, how generalizable are they, and what kind of experiments are necessary to develop them further? How do mixed-species stands compare with monocultures in relation to productivity, wood quality, and ecological stability in the face of stress and disturbances? How are the effects of species mixtures on ecosystem functioning influenced by the particular species composition, site conditions, and stand structure? How does any over- or underyielding at the forest-stand level emerge from the tree and organ level, and what are the main mechanisms behind mixing effects? How can our current scientific understanding of mixed-species forests be integrated into silvicultural concepts as well as practical forest management and planning? Do the ecological characteristics of mixed-species stands also translate into economic differences between mixtures and monocultures? In addition, the book addresses experimental designs and analytical approaches to study mixed-species forests and provides extensive empirical information, general concepts, models, and management approaches for mixed-species forests. As such, it offers a valuable resource for students, scientists and educators, as well as professional forest planners, managers, and consultants.
