Book Description
This is the first of two volumes on Gentianaceae. Comprising twelve chapters, it centres upon the characterization and ecology of Gentianaceae worldwide, with emphasis on the application of molecular and cytological approaches in relation to taxonomy. The first three chapters consider the classification of the family and review the advances in research since the earlier revision published in 2002, which resulted in the reclassification of some plants and the naming of new genera. The next chapter provides the most comprehensive report to date of the systematics of South American Neotropical woody Gentians. Other reviews include details of the Gentianaceae in Eastern Europe. The key biochemical steps that result in the diversity of Gentian flower colors, the cytology of European species and an historical account of the importance of Gentians in herbal medicines are also covered. Furthermore, an analysis of gene expression in overwintering buds is presented, discussing several aspects of plant taxonomy, phenotypic characteristics, phylogeography and pedigree. Two contributions highlight the importance of Gentians in India, and the last chapter presents evidence for the importance of Glomeromycota in developing arbuscular mycorrhizal associations with the roots of Gentians. This volume provides the basis for the biotechnological approaches that are considered in the companion book The Gentianaceae – Volume 2: Biotechnology and Applications.

Book Description
The objective of this study is to provide the background required for an understanding of the boundary dispute between Ecuador and Peru, a hardy perennial among inter-American controversies. It is not designed to propound any particular thesis, much less to take sides in the dispute. Evaluation of the significance of the positions adopted by the parties over the years have been included. Primary attention has been focused on the period after the entry into effect of the Rio Protocol of 1942 which attempted to fix the boundary between the rival states and which was guaranteed by Argentina, Brazil, Chile and the United States. Very little has previously been published on the efforts of the guarantors to work out the problems which arose in the execution of the protocol. These problems proved so intractable that the demarcation of the boundary has not yet been completed, leaving the guarantors with a residual responsibility which they may yet be called upon to discharge. In addition to the survey of the post-1942 period, it was considered desirable to include information regarding the origins of the dispute and earlier attempts at solutions. Much of this material will be appearing for the first time in English.

Book Description
Understanding diversity patterns and the effect of global change on abundance, distribution patterns and species survival are of the most discussed topics in biodiversity research. Species are disappearing worldwide, mostly due to habitat loss, but other factors like climate change are likely to increase in importance during the 21st century. Thus, one of the most worrying issues is that we still do not know the optimal abiotic and biotic requirements for population persistence of many of the still existing species, which makes it very difficult, if not impossible, to make appropriate recommendations for their conservation in terms of proposing an effective management of their sites. Analysis of these requirements is, however, strongly dependent on the taxonomic group considered and on life history strategies of the species that comprise the group. In this Research Topic, we concentrate on this issue applied to orchids, one of the most abundant groups of flowering plants with approximately 30,000 species. They are classified among the most threatened groups worldwide. Of the approximately 1000 species that have been evaluated, almost 60% are threatened, endangered or extinct. For a few orchid species, detailed records from monitoring efforts provide opportunities for comparative analyses of species declines through time. However, for most orchid species we still lack population data and there have been few studies that have focused on the environmental factors and species traits associated with the decline of orchid sites and species numbers.
