Villa Alemana, V Región, Chile Received 19 August 2014, accepted 9 December 2014 SUMMARY WALLACE, R.S. & ARAYA, B. 2015. Humboldt Penguin Spheniscus humboldti population in Chile: counts of moulting birds, February 1999–2008. Marine Ornithology 43: 107–112 We conducted annual counts of moulting Humboldt Penguins roosting on the mainland coast and on offshore islands in north and central Chile during 1999–2008. The census area included the known major breeding colonies in Chile, where many penguins moult, as well as other sites. Population size was relatively stable across years, with an average of 33 384 SD 2 372 (range: 28 642–35 284) penguins counted, but the number of penguins found at any individual site could vary widely. Shifting penguin numbers suggest that penguins tend to aggregate to moult where food is abundant. While many of the major breeding sites are afforded some form of protected status, two sites with sizable penguin populations, Tilgo Island and Pájaros-1 Island, have no official protection. These census results provide a basis upon which future population trends can be compared. Key words: penguin, Spheniscus humboldti, census, Chile INTRODUCTION penguin taking less than three weeks to moult (Paredes et al. 2003). Penguins remain on land during moult, and they return to The Humboldt Penguin Spheniscus humboldti is a species endemic sea immediately after moulting (Zavalaga & Paredes 1997). -
Large Rock Avalanches and River Damming Hazards in the Andes of Central Chile: the Case of Pangal Valley, Alto Cachapoal
Geophysical Research Abstracts Vol. 21, EGU2019-6079, 2019 EGU General Assembly 2019 © Author(s) 2019. CC Attribution 4.0 license. Large rock avalanches and river damming hazards in the Andes of central Chile: the case of Pangal valley, Alto Cachapoal Sergio A. Sepulveda (1,2), Diego Chacon (2), Stella M. Moreiras (3), and Fernando Poblete (1) (1) Universidad de O0Higgins, Instituto de Ciencias de la Ingeniería, Rancagua, Chile ([email protected]), (2) Universidad de Chile, Departamento de Geología, Santiago, Chile, (3) CONICET – IANIGLA- CCT, Mendoza, Argentina A cluster of five rock avalanche deposits of volumes varying from 1.5 to 150 millions of cubic metres located in the Pangal valley, Cachapoal river basin in the Andes of central Chile is studied. The landslides are originated in volcanic rocks affected by localised hydrothermal alteration in a short section of the fluvial valley. The largest rock avalanches, with deposit thicknesses of up to about 100 m, have blocked the valley to be later eroded by the Pangal river. Lacustrine deposits can be found upstream. A detailed geomorphological survey of the valley and dating of the landslide deposits is being performed, in order to assess the likelihood of new large volume landslide events with potential of river damming. Such events would endanger hydroelectric facilities and human settlements downstream. A total of eighteen potential landslide source areas were identified, with potential of damming up to 10^7 million cubic metres. This case study illustrates a poorly studied hazard of large slope instabilities and related river damming in the Chilean Andes, extensively covered by large landslide deposits along their valleys. -

Biggest Trees of the World Pub 13-2
Dendrology Series WSFNR13-2 January 2013 Tallest, Biggest, & Oldest Trees by Dr. Kim D. Coder, Professor of Tree Biology & Health Care Warnell School of Forestry & Natural Resources, University of Georgia Trees have a long relationship with people. They are both utility and amenity. Trees can evoke awe, mysticism, and reverence. Trees represent great public and private values. Trees most noticed and celebrated by people and communities are the one-tenth of one-percent of trees which approach the limits of their maximum size, reach, extent, and age. These singular, historical, culturally significant, and massive trees become symbols and icons of life on Earth, and our role in environmental stewardship and sustainability. What Is A Tree? Figure 1 is a conglomeration of definitions and concepts about trees from legal and word defini- tions in North America. For example, 20 percent of all definitions specifically state a tree is a plant. Concentrated in 63% of all descriptors for trees are four terms: plant, woody, single stem, and tall. If broad stem diameter, branching, and perennial growth habit concepts are added, 87% of all the descrip- tors are represented. At its most basic level, defining a tree is not species based, but is a structural definition. A tree is represented by a type of plant architecture recognizable by non-technical people. The most basic con- cepts for defining a tree are -- a large, tall, woody, perennial plant with a single, unbranched, erect, self- supporting stem holding an elevated and distinct crown of branches greater than 10 feet in height and greater than 3 inches in diameter. -

IAWA Journal, Vol. 28 (2), 2007: 125-137 WOOD ULTRASTRUCTURE OF ANCIENT BURIED LOGS OF FITZROYA CUPRESSOlDES Maria A. Castro1 and Fidel A. Roig2 SUMMARY The anatomy and ultrastructure of subfossil wood of Fitzroya cup res soides from the late Pleistocene (>50,000 14C years before present) were compared with those of extant F. cupressoides trees from southern Chile, using light microscopy (polarized light and ftuorescence), scanning elec tron microscopy coupled with an energy dispersive X-ray spectroscopy system, and transmission electron microscopy. The ancient wood showed an unchanged gross wood structure, loss of cell wall birefringence, loss of lignin autoftuorescence, and a loss of the original microfibrillar pat tern. The energy dispersive X-ray spectroscopy analysis indicated higher than normal contents of S, Cl, and Na in subfossil wood. Ultrastructural modifications in the cell wall of the subfossil wood could have important implications for further studies involving isotopic and wood anatomical measurements of ancient wood. Key words: Fitzroya cupressoides, Pleistocene subfossil wood, cell wall ultrastructure, TEM, SEM-EDXA analysis, wood anatomy. INTRODUCTION The temperate rain forest of South America has a very rich tree species assemblage with a high level of endemism (Arroyo et al. 1993). One of the natural endemies is Fitzroya cupressoides (Molina) I.M.lohnston (alerce, Cupressaceae), a tree species that grows under a relatively low annual mean temperature and high precipitation in areas ofthe southernAndes ofChile and southwesternArgentina. Tree-ring analysis revealed that Fitzroya is a slow-growing tree and is one of the longest-lived tree species in the world, known to reach up to around 3,500 years of age (Lara & Villalba 1993). -

Bolivia 7–25 September 2007 Participants: Didier Godreau Rolf Gräfvert Helge Grastveit Andrew Self Dennis and Margaret Weir Leader: Nick Acheson and Leo Catari (driver) Yellow-tufted Woodpecker Day 1 Overnight flight from London via Miami. Day 2 Having arrived smoothly courtesy of American Airlines, we immediately set to work in the savannahs surrounding the Viru Viru airport. Here we were delighted to see Greater Rhea, Red-winged Tinamou, Campo Flicker and flocks of Blue-crowned Parakeets. After a fine lunch in Santa Cruz we headed for the Piraí River on the west side of the city, and the Urubó savannahs beyond it. Once we found a sheltered spot out of the wind we had great birding, seeing, among many others, Speckled Chachalaca, Yellow-tufted Woodpecker, Blue-winged Parrotlet, Green-cheeked Parakeet, Golden-collared and Chestnut-fronted Macaws, Chestnut-eared Aracari, Thrush-like Wren, and Greater Thornbird. A pair of Titi Monkeys was also popular here. Day 3 This morning was spent at the Jardín Botánico, ten kilometres east of the city of Santa Cruz. By the roadside we saw White Woodpecker and Red-crested Cardinal and around the pond we found a dozy Brown-throated Three- toed Sloth, Social and Rusty-margined Flycatchers (very thoughtfully perched next to each other for ease of comparison), Blue-crowned Trogon, Blue-crowned Motmot and Narrow-billed Woodcreeper. Highlights in the forest included Rufous Casiornis, White-wedged Piculet, White-crested Tyrannulet, Fawn-breasted Wren, Ferruginous Pygmy-owl and a family of Silvery Marmosets. This afternoon we drove to Los Volcanes where we were greeted by Andean Condor, Military Macaw, Channel-billed Toucan, Red-billed and Turquoise-fronted Parrots and noisy, sky-filling flocks of Mitred Parakeets. -

chapter 6 Claudio Latorre, Julio L Betancourt, Jason A Rech, Jay Quade, Camille Holmgren, Christa Placzek, Antonio JC Maldonado, Mathias Vuille and Kate Rylander Late Quaternary history of the Atacama Desert Of the major subtropical deserts found in the Southern Hemisphere, the Atacama Desert is the driest. Throughout the Quaternary, the most pervasive climatic infl uence on the desert has been millennial-scale changes in the frequency and seasonality of the scant rainfall, and associated shifts in plant and animal distributions with elevation along the eastern margin of the desert. Over the past six years, we have mapped modern vegetation gradients and developed a number of palaeoenvironmental records, including vegetation histories from fossil rodent middens, groundwater levels from wetland (spring) deposits, and lake levels from shoreline evidence, along a 1200-kilometre transect (16–26°S) in the Atacama Desert. A strength of this palaeoclimate transect has been the ability to apply the same methodologies across broad elevational, latitudinal, climatic, vegetation and hydrological gradients. We are using this transect to reconstruct the histories of key components of the South American tropical (summer) and extratropical (winter) rainfall belts, precisely at those elevations where average annual rainfall wanes to zero. The focus has been on the transition from sparse, shrubby vegetation (known as the prepuna) into absolute desert, an expansive hyperarid terrain that extends from just above the coastal fog zone (approximately 800 metres) to more than 3500 metres in the most arid sectors in the southern Atacama. Our study focuses on rodent middens (cf. Betancourt et al. 1990). These are amalgamations of plant remains (including seeds, fl owers, leaves and wood), bones, insects, feathers and rodent faeces, glued together within a crystallised matrix of rodent urine. -
