A REVISION of TRISETUM Victor L. Finot,' Paul M
A REVISION OF TRISETUM Victor L. Finot,' Paul M. Peterson,3 (POACEAE: POOIDEAE: Fernando 0 Zuloaga,* Robert J. v sorene, and Oscar Mattnei AVENINAE) IN SOUTH AMERICA1 ABSTRACT A taxonomic treatment of Trisetum Pers. for South America, is given. Eighteen species and six varieties of Trisetum are recognized in South America. Chile (14 species, 3 varieties) and Argentina (12 species, 5 varieties) have the greatest number of taxa in the genus. Two varieties, T. barbinode var. sclerophyllum and T longiglume var. glabratum, are endemic to Argentina, whereas T. mattheii and T nancaguense are known only from Chile. Trisetum andinum is endemic to Ecuador, T. macbridei is endemic to Peru, and T. foliosum is endemic to Venezuela. A total of four species are found in Ecuador and Peru, and there are two species in Venezuela and Colombia. The following new species are described and illustrated: Trisetum mattheii Finot and T nancaguense Finot, from Chile, and T pyramidatum Louis- Marie ex Finot, from Chile and Argentina. The following two new combinations are made: T barbinode var. sclerophyllum (Hack, ex Stuck.) Finot and T. spicatum var. cumingii (Nees ex Steud.) Finot. A key for distinguishing the species and varieties of Trisetum in South America is given. The names Koeleria cumingii Nees ex Steud., Trisetum sect. Anaulacoa Louis-Marie, Trisetum sect. Aulacoa Louis-Marie, Trisetum subg. Heterolytrum Louis-Marie, Trisetum subg. Isolytrum Louis-Marie, Trisetum subsect. Koeleriformia Louis-Marie, Trisetum subsect. Sphenopholidea Louis-Marie, Trisetum ma- lacophyllum Steud., Trisetum variabile E. Desv., and Trisetum variabile var. virescens E. Desv. are lectotypified. Key words: Aveninae, Gramineae, Poaceae, Pooideae, Trisetum. -

PATAGONIA Located in Argentina and Chile, Patagonia Is a Natural Wonderland That Occupies the Southernmost Reaches of South America
PATAGONIA Located in Argentina and Chile, Patagonia is a natural wonderland that occupies the southernmost reaches of South America. It is an extraordinary landscape of dramatic mountains, gigantic glaciers that calve into icy lakes, cascading waterfalls, crystalline streams and beech forests. It is also an area rich in wildlife such as seals, humpback whales, pumas, condors and guanacos. The best time to visit Patagonia is between October and April. Highlights Spectacular Perito Moreno Glacier; scenic wonders of Los Glaciares National Park; unforgettable landscapes of Torres del Paine; breathtaking scenery of the Lakes District. Climate The weather is at its warmest and the hours of daylight at their longest (18 hours) during the summer months of Nov-Mar. This is also the windiest and busiest time of year. Winter provides clear skies, less windy conditions and fewer tourists; however temperatures can be extremely cold. 62 NATURAL FOCUS – TAILOR-MADE EXPERIENCES Pristine Patagonia Torres Del Paine National Park in Patagonia was incredible!

Y TIP. DEL COMERCIO 1940 Dr. Alfredo Jahn EXCURSIONISMO Y ALPINISMO Historia de su Evolución El 18 de abril de 1933celebró el “Centro Excursionista de Caracas” el tercer aniversario de su fundación. Este centro deportivo me había honrado con el nombramiento de Presidente Honorario y me exigió que dictase una conferencia en la velada pública que a tal fin estaba organizando el Ateneo de Caracas. Gustosamente accedí a ello, haciendo un recuento histórico del desarrollo del alpinismo mundial. He creído que su publicación puede ser interesante y útil no sólo a los deportistas sino también a todas aquellas personas amantes de la naturaleza, especialmente a aquellas que se dedican al estudio de las Ciencias con ella relacionadas. Ya que el intimo conocimiento y práctica de este deporte es uno de los medios de que deben valerse los exploradores de montaña con fines científicos. -

Mariano Masiokas, Lidia Ferri, Laura Zalazar, Pierre Pitte, Lucas Ruiz, Mariano Castro, Hernán Gargantini, Melisa Giménez, Gustavo Costa, Rodolfo Crimi, Ricardo Villalba On October 2010, the Argentinean Senate approved the Law 26639 for the “Preservation of Glaciers and Periglacial Environments” üThis National law considers glaciers and periglacial features as strategic water reserves ü Declared these reserves as public goods üOne important outcome of this law was the creation of the National Glacier Inventory (NGI) to identify and map all the glacier and periglacial landforms that act as strategic water reserves in the Argentinean Andes üThe inventory was assigned to the Argentinean Institute for Snow, Ice and Environmental Research (IANIGLA) in collaboration with the National Secretary of Environment and Sustainable Development What is included in the inventory • Clean ice glaciers • Debris-covered glaciers Area ≥ 0,01 km2 • Permanent snow patches • Rock glaciers Methods The NGI was largely based on remote sensing techniques and datasets The methodology followed international guidelines (e.g. from GLIMS) for the development of glacier inventories Methods But also included field campaings to verify the mapping and classification of ice masses The NGI project includes three types of studies Level 1: Identification, mapping and characterization of all ice masses that act as water reserves in the country Level 2: Assessment of recent glacier fluctuations on selected areas along the Argentinean Andes Level 3: mass balance, meteorological -
Round the Llanquihue Lake
Round the Llanquihue Lake A full day spent exploring the corners of this magnificent lake. The third biggest of South America, and the second of Chile with 330sq miles. It is situated in the southern Los Lagos Region in the Llanquihue and Osorno provinces. The lake's fan-like form was created by successive piedmont glaciers during the Quaternary glaciations. The last glacial period is called Llanquihue glaciation in Chile after the terminal moraine systems around the lake. We will enjoy unique views from the Volcano Osorno introducing us to the peaceful rhythm of a laid back life. Meet your driver and guide at your hotel. Bordering the south lake Llanquihue acrros the Vicente Perez Rosales National Park visiting the resort of Ensenada and the Petrohue River Falls. The tour will continue up to the Osorno Volcano, Ski Resort, 1200 mts asl. (3937 feet asl.) where you will get spectacular views of the Mt Tronador, Volcano Puntiagudo,Llanquihue lake, and if is clear enough even the Reloncavi sound and of course the whole valley of Petrohue river. For the itchy feet we can go for a short walk to the crater rojo and back. (1hr) Or optional chair lift instead. You can bring your own lunch box and have it here or get something at the restaurant. Continuation to the northern border of Llanquihue Lake driving across some of the least visited sides of the lake where agriculture and cattle ranches take part of the local economy passing through Cascadas village. We will reach the picturesque village of Puerto Octay, located on a quiet bay enclosed by the Centinela Peninsula and then to the city of Frutillar, with its houses built in German style with lovely gardens represent the arquitecture in the mid 30/s when the first settlers arrived to begin a hard working life in the south. -

Comparative Analysis Between Gill Netting and Sport Fisher Catches in a Small Patagonic Andean Lake: Its Implications for Resource Evaluation and Management

Centro Regional Universitario Bariloche, Universidad Nacional del Comahue, Argentina. 3. CENPAT - CONICET Puerto Madryn, Chubut. Argentina. ABSTRACT. Knowledge of lake fish communities of Argentine Patagonia has grown in the past 20 years thanks to the use of gill nets. However, National Park officials and Fisher organizations dislike their use and would prefer the use of recreational fisher catch data. The present paper addresses advantages and disadvantages of using gill nets as compared to fishers. This was accomplished by analysis of gill net and fisher catch data from Lake Guillelmo, Parque Nacional Nahuel Huapi for the period 1997-1999. Both sets of data revealed the presence of only two salmonids, brook trout (Salvelinus fontinalis) and rainbow trout (Oncorhynchus mykiss). However, relative abundances of each species differed between fishing techniques, rainbow trout being dominant according to fisher catches and brook trout according to gill net catches. In addition, differences in size, age and spatial distribution brought about by the highly selective nature of fisher catches were clearly observed. This shows that fisher catch data can only be used to assess existing recreational Patagonian lake fisheries in terms of current or historical trends in catch composition, structure and fishing pressure.
