Das Standardwerk zur Klima- und Wachstumsdebatte in der 9. Auflage mit einem Nachwort von Harald WelzerDie Menschheit kann mehrere Entwicklungswege wählen - bereits 1972 und 1992 haben die Autoren der Grenzen des Wachstums solche Möglichkeiten beschrieben. Dabei setzten sie das systemische Denken in Zukunftsszenarien um. Ihre Ergebnisse riefen schon damals zum Handeln auf, denn wir verlangen seit den späten 70er-Jahren der Erde so viel ab, dass ihre Tragfähigkeit überschritten ist. In den Szenarien des 30-Jahre-Update mit aktuellen Daten wird deutlich, dass wir den großen Kurswechsel dringend brauchen - eine Wende zur Nachhaltigkeit mit drastischen materiellen und strukturellen Veränderungen.Wir können diesen Weg gehen, aber wir müssen es wollen!  (lib)

This highly-readable Open Access textbook provides basic background information about marine mammals and anthropogenic impacts on them. The book includes inspiring exercises for education school programs in natural sciences. The book also provides advice on career paths using case studies of marine scientists and veterinarians describing their journeys from student to profession. By sharing real-life career paths, readers find answers to questions such as ¿What needs to be considered when choosing a career in science?¿ and ¿What kind of tasks do scientists undertake on a daily basis?¿Marine mammals are amongst some of the most celebrated creatures on Earth, with their high intelligence, social and communicating skills, and capacity for deep diving. Alongside general information about marine mammals, the book aims at generating awareness of the impact of litter and noise pollution on the marine environment using marine mammals as an example. Huge numbers of marine animals, including marine mammals, die every year from entanglement in fishing gear, by ingestion of litter or because of chemical pollution. In the last decade many technological and scientific tools have been developed to aid research, for instance miniaturised sound recorders which can be attached to cetaceans and seals and record noise levels around them, their vocal production as well as their diving behaviour. This Open Access textbook can be used by undergraduate students interested in the fundamentals of marine mammal biology and medicine, and in pursuing the profession of a marine scientist. (lib)

This book is two books in one and contains the following stories:Save the Philippine Ironwood and other critically endangered highly valuable tropical hardwood species!These wonderful trees are most likely going to go extinct without immediate intervention. We can propagate more than 22 different hardwood species now, if you help us to do so. We have an operating nursery and we can produce tens of thousands of high quality seedlings for reforestation every year, if there is someone who has land to plant them into the ground.Please help us to get continuous annual planting started!At December 2019, our nursery had still over 2,000 pieces of 17 different Palawan hardwood tree seedlings in stock, but we cannot find enough buyers who would plant them!----------------------------------------------------------------------------------------A research on the availability, germination and propagation of selected Palawan hardwood tree species: the Mangkono (Ironwood), Ipil, Mountain Agoho and Narra - It included the following field research:* Surveys to find potential Mother-Trees* Availability study of seeds and wildlings* Seed germination analysis for selected species* Observations and experiments on survival of seedling in nursery and out-planted.There is practically no research on these species and this is an open invitation to study more about these magnificent species.The surveys located enough Mother-Trees to successfully save, protect, propagate and educate about these hardwood species.Some species can be easily propagated from seeds, while many others must be propagated from wildlings, as of now, due to extreme difficulty to find enough seeds or very low-germination rates.----------------------------------------------------------------------------------------I would love to plant many trees in the field and help to organize more research, but I have no more resources to do enough. I am asking for all of you who love to plant trees to read what I have done this far and join my efforts to plant million trees first in Palawan and then other islands in the Philippines. (lib)

Gewässerschutz in Deutschland wurde und wird weitgehend technik-bezogen betrieben. Dagegen orientiert sich die dänische Praxis seit langem an standorttypischen Organismen, wie z.B. der Forelle mit ihren Ansprüchen an den Lebensraum Bach. Dieses wird sowohl bei Zielsetzungen wie bei Soll-/Ist-Vergleichen eingesetzt. Anstelle theoriebeladener Ansätze steht die eher spielerische Herangehensweise, die lebendige Lebensräume erfolgreich reaktiviert. Das Buch vermittelt die dabei über Jahrzehnte gewonnenen Erkenntnisse, angepasst an deutsche Verhältnisse.2022 ff.: Wir befinden uns inzwischen im letzten (?) Verlängerungszeitraum der Wasserrahmenrichtlinie. Die Gewässerlebensräume in Deutschland wurden nicht hinreichend verbessert, ihre mögliche Artenvielfalt und Individuendichte nicht annähernd erreicht.Insofern stellt das im Jahr 2000 aufgelegte Werk von Madsen & Tent weiter eine wesentliche praxisbezogene Grundlage für das Handeln Offizieller in Verwaltungen und Wasser- / Gewässerpflegeverbänden sowie von Laien (z.B. Bachpatenschaften) dar. (lib)

Am Rand unserer alltäglichen Wahrnehmung, kaum sichtbar für das Auge, liegt eine andere Welt: ein Regenwald en miniature, ein Mikrobiom, bestehend aus Moosen, den primitivsten aller Pflanzen. Sie haben weder Blüten, Früchte noch Samen und bringen es dennoch auf 22 000 Arten. Sie haben keine Wurzeln, und doch sind sie seit ihrer Entstehung vor mehreren hundert Millionen Jahren tief verbunden mit dem Leben unzähliger anderer Organismen. Anschaulich und kunstvoll bietet Robin Wall Kimmerer in ihren persönlichen, mit indigenen Wissensformen und wissenschaftlicher Erkenntnis angereicherten Reflexionen Einblick in die Vielfalt dieser genügsamen, allen Widrigkeiten trotzenden Organismen. Und zeigt damit, dass der bloßen Existenz der Moose nicht nur aufgrund ihrer Schönheit unsere Aufmerksamkeit gelten sollte. Dem ersten Blick verborgen, offenbaren sie uns Blatt für Blatt eine Botschaft, die unbedingt gehört werden muss: wie es möglich ist, sich mit der Welt aufs Innigste vertraut zu machen und noch unter schwierigsten Bedingungen in Verbundenheit zu überleben.

These books bring together a panel of expert arbovirologists who recall the history of arbovirology from very personal perspectives. In these timely volumes, the authors describe seminal moments in their experiences in the field and how they integrated these findings with lab studies to further clarify the ecology and epidemiology of diverse arboviruses. Authors identify the most pressing questions that remain to be answered, providing a basis for current research and a stimulus to engage those entering the field. Over the last 20 years a generational gap has developed between the giants of arbovirus research and discovery and the new generation. This gap developed due to an ebbing of training and investment in passing the scepter to the next generation, leading to a lack of continuity among the generations that threatens to derail the rich history of virus discovery, field epidemiology and understanding of the richness of diversity that surrounds us. This lack of continuity may have immediate and disastrous consequences for public health when yet to be discovered arboviruses emerge. The purpose of these books is to bridge this gap by providing a historical context for the work being done today and provide continuity between the generations. To this end, the books provide a narrative of the thrill of scientific discovery and excitement of field adventures and lab studies of that generation -- essential reading for every arbovirologist, and highly recommended for all virologists and public health officials, as well as those students considering future research options. Volume I consists of the personal reflections of arbovirologists who played a significant role in the advancement of arbovirology across the globe. Volume II transitions to descriptions of region-specific and virus family-specific perspectives of arbovirology, as well as recollections of the early events of molecular advances and pathogenesis studies.

In 2015 the first edition of this book was published before the Ballast Water Management (BWM) Convention entered into force. To our knowledge this was and still is the first comprehensive book on BWM worldwide. It provided an overview of possible solutions to the complex issue of BWM. It further outlined consequences and implications to address the ballast water "problem" in line with provisions of the BWM Convention considering environmental, shipping, legal and policy perspectives. The previously addressed subjects remain essential, but new subjects appeared which more recently have proven to be critical for the effective BWM Convention implementation. After the first book content was already agreed and in preparation, new advances were achieved in BWM-related research around the world. Further, new experience was gained and issues came out during the preparation processes of countries for the BWM Convention implementation. The editors of the first book remained heavily involved in BWM-related research and other processes, hence these new critical BWM issues and subjects are now dealt with in the second edition of this book to complement the first one. In essence, this new book covers main issues that arose recently during the implementation of the BWM Convention. Scientists and experts with extensive experience in these subjects from around the globe from academic and private sectors, as well as national administrations, were involved in the preparation of this book.

Chilean Patagonia, located at the southwestern tip of South America, is one of the last regions on earth where highly intact environments predominate. With a coastline that extends along some 100,000 km of fjords, channels, and islands, it has one of the world¿s most extensive marine-terrestrial interfaces. Local place-based and Indigenous cultures and management practices are a vital presence across the region, while the long and rich history of conservation efforts have resulted in officially protected areas covering over 50% of the land and 41% of the coastal-marine area. However, Chilean Patagonia is increasingly facing anthropogenic pressures associated with increased infrastructure and access, salmon aquaculture, extractive industries, and the spread of invasive exotic species. Despite widespread recognition that Chilean Patagonia represents a unique global reservoir of socio-natural heritage, to date there has been no region-wide assessment of the scientific evidence of the conservation status of its ecosystems or the priorities for their effective conservation.Conservation in Chilean Patagonia: Assessing the state of knowledge, opportunities, and challenges is the first book to gather and synthesize the available scientific and socio-environmental information related to Patagonian conservation. It presents the collaborative work of 68 researchers and local experts, representing a range of specialties and perspectives, including: biology, ecology, socio-ecology, fisheries, aquaculture, anthropology, economics, geography, tourism, cryosphere, oceanography, climate and global change. The book¿s 18 chapters focus on the status of key ecosystems and conservation tools, and provide recommendations toward the construction of a renewed, inclusive, and integrated conservation agenda for the Chilean Patagonian region. It provides an essential primer for anyone interested in the future of this ecologically vital region, as well as lessons on interdisciplinary collaboration and integrated analysis of conservation issues useful for conservation practitioners and scholars. This is an open access book.This book is a translation of an original Spanish edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. (lib)

Volume 166 of Zoologica represents the first extensive comparative study of the egg surface morphology of stick and leaf insects (Phasmatodea). The eggs of 314 representative species are compared and described in detail, with particular focus on the functional surface structures. This study combines a review of egg surface structures of 126 taxa visualised in various literature sources and adds scanning electron microscopy investigations of 188 taxa visualised for the first time. The eggs of Phasmatodea stand out among insects, because of the mineralization of the layered egg shell. This egg shell is a structural basis, which is modified in multiple different ways to facilitate various functions of the surface of the egg. Phasmids occur worldwide and are adapted to different environmental conditions, this lineage arose as a model for the study of evolutionary scenarios and ecomorphological adaptations. The taxa considered cover a broad spectrum of phylogenetic lineages within Phasmatodea, the entire biogeographic distribution and different life history aspects of phasmids to facilitate investigation of relationships between the egg structures, ecology and phylogeny. There are three different levels of surface structures found in phasmid eggs that can be categorised by their morphology. The majority of the corresponding categories occurs convergently in several of the taxa considered, suggesting a high relevance of the ecological background of the species for the development of certain egg surface features. The functional relevance of all surface structures is discussed and evaluated with reference to previous studies of similar structures in other insect groups and artificial model systems. This study is of interest to biologists interested in biological surfaces, functional morphology, as well as the evolution, ecology and morphology of Phasmatodea. Furthermore, this monograph features a comprehensible description of the egg morphology of a high number of phasmid species, generously illustrated with high resolution scanning electron microscopy images, and therefore is a substantial reference work for future researchers working on this character system.

There has been a dramatic increase in theoretical and practical studies on insect natural enemies over the last decades. The appeal of insect predators and, in particular, parasitoids, as research animals derives from the relative ease with which many species may be cultured and experimented on in the laboratory, the simple life-cycles of most parasitoid species, and the increasing demand for biological pest control as a key component of the integrated pest management approach.There is now a very substantial literature on insect natural enemies and thus a great need for a general text that enquiring students or research workers can use in deciding on approaches and techniques that are appropriate to the study and evaluation of such insects. This book fulfils that demand. It is a considerably updated and expanded version of a previous best-seller and provides an account of major aspects of the biology of predators and parasitoids, punctuated with information and advice onwhich experiments or observations to conduct and, importantly, how to carry them out. Guidance is provided, where necessary, on the most recent further literature that may need to be consulted on given topics.While researchers can now refer to several books on parasitoids and predators, Jervis¿s Insects as Natural Enemies is unique in emphasising practicalities. It is aimed at students and professionals working in universities and both government and commercial institutes in the fields of integrated pest management, agriculture, horticulture and forestry, as well as those interested in fundamentals of behavioural, population, community and evolutionary ecology.
