The Flore du Gabon series provides access to the information on the great botanical wealth of this central African country, reputedly harbouring the richest lowland rain forest in Africa. With 12.5% of all plant species being endemic to the country and some 85% of its surface being covered with a highly diverse lowland rain forest, Gabon is a botanical paradise and hotspot. Over 10% of its surface is under protection, which renders this country a Mecca for conservationists, ecotourism and scientists. For an effective conservation management, but also to support a wise and sustainable use of this unique diversity, it is essential to be able to simply identify the plants that play such an important role, be it as food for gorillas, birds, etc., as medicine, nutrition or timber, or just as one of these essential elements of the ecological network. The Flore du Gabon provides this essential tool for reliable identification, its editorial team making sure the identification keys are simple and straightforward, descriptions having diagnostic features stand out in bold, and clarifying illustrations. As such, it hopes to assist researchers, foresters, conservationists, amateur botanists and policy makers alike and to contribute to the survival of Gabon’s unique biodiversity.
The Flore du Gabon series was started in 1961 by the Muséum national d’Histoire naturelle (MNHN) in Paris and until 2004 no less than 37 volumes were published dealing with about 80 families and over 2200 species. In 2006, the Wageningen branch of the National Herbarium of the Netherlands (NHN), now part of Naturalis Biodiversity Center, who had built up their knowledge on the Gabonese flora for over 35 years, continued its production. In 2014, the series was continued jointly by Meise Botanic Garden and Naturalis. End of 2018, almost 3300 species have been dealt with, while around 1250 await their treatment.
For this final challenge, additional funding was obtained from the Alberta Mennega Foundation. This should render it feasible to produce two or three volumes each year and finish the Flore du Gabon series by 2023.
A Field Guide, Third enlarged edition
This field guide of the wildflowers in the Azores islands provides short species portraits with full- colour photographs for 645 vascular plants growing wild in the archipelago and mentions key distinguishing characters for the remaining species. More than 1100 of the about 1200 species of the flora of the Azores are covered in this book, the most comprehensive treatment for these islands. Not only the most common species but also rare and unusual plants of thrilling beauty are illustrated and described, some of them for the first time.
Much emphasis is given to endemic species that can be found nowhere else in the world and invasive plant species that have been introduced to the Azores from all over the globe. They describe a serious threat to the native ecosystems in the archipelago. In addition to the scientific name, the Portuguese, English, German, and French names are given for each species. A glossary in English, Portuguese and German helps readers to better understand the scientific terminology.
An invaluable aid for all plant lovers in the Azores: students, teachers, farmers, rangers, scientists, tourists.
Carex L. (Cyperaceae) in Europe vol 1;
Accepted names, hybrids, synonyms, distribution, chromosome numbers.
About the book
On 21 December 2011 Carex Europaea, volume 1, was published. This book was sold out rather quickly, so in 2015 was decided to produce an updated e-book version. In the e-book some improvements were made on the text of the 2011 version. Besides, literature within the period 2011-2015 had been taken into account. And now, in 2021, a third, completely updated edition will be published. This book is a documentary book about the nomenclature and distribution of European taxa and hybrids within the genus Carex (Cyperaceae). Of all European taxa are given their accepted names and all known synonyms, both with full citation. Altogether there are more than 4500 names involved. Of all taxa is given their distribution within Europe per country, and worldwide is given their general distribution. Providing they are known the chromosome numbers (2n) are given for accepted taxa. All known European hybrids are mentioned, most of them provided with a name, the others with only their hybrid formula. Of all hybrids is given their European distribution as well, albeit probably incomplete. In the back of the book more than 140 pages present full colour photos of about 2/3 of all European species and some hybrids. The photos are meant «to give all the names a face». This book aims to be a reference work for everybody working in the field of Botany or Nature Management or interested in the genus Carex.
REPRINT planned for spring 2023.

Catalogus trilobitorum cum figuris (Trilobites carbonici et permici, X: Chlupaculinae, Diacoryphinae et Menorcaspidinae)
Im vorliegenden Band des Katalogs der Karbon- und Perm-Trilobiten werden drei neue Unterfamilien behandelt, die Chlupaculinae, Diacoryphinae und Menorcaspidinae. Fast alle zumeist des Tiefwasser-Bereiches (Kulm-Fazies) zugehörigen 23 Gattungen wurden erst in den beiden zurückliegenden Jahrzehnten entdeckt. Im „Treatise“ (1979) ist erst eine von ihnen vorhanden, Diacoryphe. Alle drei Unterfamilien stimmen überein in ihrer stratigrafischen Beschränkung auf das Unter- Mississippium (Unter-Karbon). Ihr geografischer Schwerpunkt liegt in Europa, doch kommen einige Arten auch in Asien und Afrika vor. Sie stimmen ferner – entsprechend ihres Lebensraumes – überein in der Tendenz zur Erblindung. Zylindrisch aufgeblähte Wangen-Stacheln treten in allen drei Unterfamilien auf, nie aber bei allen zugehörigen Gattungen. Die Unterschiede zwischen den drei Unterfamilien werden bei der Darstellung der jeweiligen Unterfamilie erläutert.
A Survey of Nigeria’s Cocoa Sector
This book presents studies and papers by academics, researchers and policy makers in various universities and research institutes in Nigeria. It is on historical issues related to the development of Nigeria’s Cocoa sector and contemporary challenges associated with its production and commercialisation across the southern part of Nigeria. Different aspects have been examined at micro and macro levels. These include social, economic and environmental factors as well as the consequences for the livelihood of actors and the growth of the sector.
…of Environmental Goods and Services in North-Eastern Namibia
Understanding human-nature relationships and their contribution to managing socio- ecological systems remains a global challenge. One of the reasons is the lack of integrated assessments of how nature is valued across different knowledge systems.The valuation of nature is dominated by economic values, and poorly reflects multiple values from different knowledge systems. Values from traditional knowledge systems are underrepresented despite being significant as people's interaction with nature is guided by socio-cultural systems. This study integrates two interdisciplinary methodological approaches, namely photovoice to generate values from a sociocultural perspective, and contingent valuation method to generate values from an economic perspective. The study was conducted in northeastern Namibia where rural societies are faced with the challenges of being integrated into a market economy and undergoing changes related to the commodification of natural resources, mainly the forest which is under the community forest regime, and products sold through permits system. The main question of the study is how rural societies value nature and how are values affected by the commodification process? The results highlight that each method, though being from different ontologies, derives complementing values providing insights of people's relationship with nature. Socio-cultural values are multidimensional and reflect shared importance like identity, sense of belonging, and sacredness, but also livelihood development which is a social obligation interlinked to values from an economic perspective. The study provides evidence that the commodification of nature is causing consequences like social inequity, alienation from nature, and privatization of natural resources as competition for products and markets increases. The issues shared are happening due to power and price disparities, as a result of poor governance including the absent role of traditional institutions and practices. The book suggests that if management is not improved, commodification can potentially suppress shared values, and hinder people to manage their socio-ecological systems upon which depend for livelihood and socio-cultural values.
