Modern birds (Neornithes) are represented by two big lineages, the Palaeognathae (Tinamiformes + Ratitae) and the Neognathae [Galloanserae + Neoaves (Metaves + Coronoaves)]. Both clades sum approximately 10,000 species of which 60% are Passeriformes (the most diverse clade of terrestrial vertebrates). A comparison between the past and the present reveals a complex and hallmarked evolutionary and biogeographic history which would have begun over 65 million years ago. For South America (SA) this includes: (1) the presence of taxa with uncertain affinities and the absence of Passeriformes during the Paleogene; (2) a progressive and accelerated increase of the species starting at the Neogene (Miocene); (3) important extinct lineages (e.g. Phorusrhacidae, Teratornithidae) that migrate to North America after the rising of the Panamá isthmus; (4) groups with major diversification in the Neogene that survives nowadays represented by scarce species endemic of SA (Cariamidae) or that inhabits mainly in the southern hemisphere (Anhingidae); (5) very diverse living groups with scarce (e.g., Passeriformes) or none (e.g., Apodiformes) fossil record in SA, which stem-groups are registered in Europe. Apparently, the changes in diversity of the south American Neornithes have been the result of successive radiation, biogeographic connections with North America and in a minor scale, some extinctions. The opening of the Drake ́s passage and the occurrence of the circumpolar Antarctic flow are not sufficient causes to explain the highly disparity between the weddelians penguins (Sphenisciformes) of Antartica and those of the patagonian Atlantic Ocean.

The first synthesis of current knowledge of forest and wetland birds in the world’s southernmost forests, this book contains both original work by Rozzi and Jiménez and the results of a decade of research conducted by the scientists associated with the Omora Park. The first part is a guide to the forest bird populations and habitats in the Reserve, and a summary of the data recorded for the bird species captured with mist-nets and banded. The information is given in two pages for each species, with English, Spanish, and scientific names, as well as a full-color photo, distribution maps, a table with original morphological information, a figure indicating abundance rates, and a brief description of the species’ main features. The second part is a selection of twenty-two published articles on ornithological research at Omora Park during its first decade of studies, from 2000 to 2010. Eleven of the twenty-two articles were originally published in Spanish and are here translated and available to a larger readership. The reprinting of these articles in one place provides interested scientists, students, and wildlife managers a unique and convenient resource. “This book has two important sources of information: original morphological data and the compilation of all publications about the birds in the southern extreme of South America. I think the book will have great significance.”—Victor R. Cueto, professor of natural sciences, Universidad de Buenos Aires, Argentina “A wonderfully rich and in-depth contribution to Sub-Antarctic Ornithology.”—Julie Hagelin, senior research scientist, University of Alaska, Fairbanks

Am Anfang steht der Plan von der erstmaligen Durchquerung des weißen Kontinents. Doch das gewaltige Naturwunder Antarktis wird im Jahr 1915 für die Crew der 'Endurance' zur Hölle aus Eis. Beharrlich verfolgt Expeditionsleiter Sir Ernest Shackleton bald nur noch ein Ziel: 28 Männer lebend wieder in die Zivilisation zurückzubringen. Die faszinierende Geschichte einer Irrfahrt ans Ende der Welt. "Gebt mir Scott als wissenschaftlichen Expeditionsleiter ..., gebt mir Amundsen für eine störungsfreie und effiziente Polar-Expedition, aber wenn sich das Schicksal gegen euch verschworen zu haben scheint, dann fallt auf die Knie und betet um Shackleton."
