III. Representative Bryophyte and Lichen Species of the Miniature Forests of Cape Horn / Especies Representativas de Briofitas y Liquenes de Los Bosques en Miniaturia del cabo de Hornos

Bernard Goffinet and Ricardo Rozzi and Lily Lewis and William Buck and Francisca Massardo University of North Texas Press PDF

Acrocladium auriculatum (Acrocladiaceae)

Characters for field identification: Plants grow horizontally and form highly branched mats, usually with many sporophytes. The branches are spreading and conspicuously pointed. The leaves are broad and spoon-shaped, with hollow blades and rounded apices. The operculum of the capsules are characteristically white.

Habitat: Soil and decaying tree trunks in Nothofagus forests; rocks and live tree trunks in humid

Nothofagus forests

Distribution: Southwestern South America.

Did you know? The characteristic pointed branches have given this moss its generic name

Acrocladium [Acro (tip) + clad (branch)]. The name auriculatum [auricul (auricle) + tum (lobed leaf base)] describes the heart shaped leaves. Many of the names given to bryophytes describe characteristic features of the particular species or genus.

Introduction

Ochratoxin A (OTA), International Union of Pure and Applied Chemistry (IUPAC) name: l-phenylalanine-N-[(5-chloro-3,4-dihydro-8-hydroxy-3-methyl-1-oxo-1H-2benzopyran-7-yl) carbonyl]-(R)-isocoumarin (Ringot et al., 2006), is a mycotoxin, a product of the secondary metabolism of moulds, and is one of the most common naturally occurring mycotoxins that contaminates a wide range of different plant products including cereals, coffee beans, cocoa, nuts, spices, dried fruits, beer and wine

(Miraglia et al., 2002). OTA is a compound with recognized nephrotoxic activity, which is possibly involved in Balkans endemic nephropathy (BEN) (Vrabcheva et al.,

August

Gary Lantz University of North Texas Press PDF

August

The view from atop the refuge’s Mount Scott takes in a large slice of the Southern Plains, with most that meets the eye rolled out as flat as the proverbial pancake. The exception is this jagged backbone of granite rising over 2,000 feet in elevation in places, a stark contrast to the lowland prairie below, much of it composed of rubble washed down from the mountains over millions of years.

West of the refuge the Wichitas continue to pop up and out of wheat fields and cattle pasture in a dimpled march toward the setting sun. The outcrops come to an abrupt end at Quartz Mountain

State Park north of the city of Altus. Beyond that, the eye strains to encompass seemingly endless miles of gouged and eroded prairie, some of it brown and level, some sliced up and red as a rooster’s comb, some with exposed layers of white gypsum rock. More than anything else as this August morning ebbs, the wind-whipped and heat-drenched grassland seems parched and in need of a drink. The effect intensifies under a furnace blast of sunlight that, at midday, robs the landscape of shadows and color.

10: Future Expansion of the Arctic Dinosaur Record

Roland A. Gangloff Indiana University Press ePub

The Colville River: The Red Deer River of the Arctic?

The southern Alberta buffalo plains greet you with their vast grain and forage fields, slight topographic undulations, endless skies, scattered ranches, and small sleepy towns as you proceed eastward from the hustle and bustle of urban Calgary. If you had no previous knowledge of the region’s geography, within an hour you would find yourself trying to fend off the boredom of what seems to be endless flatlands that characterize most of the 90 miles (145 kilometers) to Drumheller. When you finally see the sign that directs you towards Drumheller, you turn north and slowly descend through a series of roadcuts that fail to stimulate even the ardent field geologist. However, this soon changes in dramatic fashion as you reach the outskirts of the small town of Drumheller and the gently meandering Red Deer River. The stacks of sedimentary strata interspersed with dark lenses of coal, lens-shaped ancient channel sands and conglomerates complexly sculpted into labyrinthine badlands delight even the jaded geologist’s eye. Drumheller is about midway along the Red Deer River, which winds its way east, then south, then east again for over 400 miles (650 kilometers) as it seeks a confluence with the Saskatchewan River. This incised river valley was host to important early twentieth-century coal mining operations. It is now the heart and soul of Alberta’s Cretaceous dinosaur country. This is where the magnificent Royal Tyrrell Museum of Palaeontology is to be found nestled within the Red Deer River badlands, just a few miles to the northwest of the center of Drumheller. If you follow the Red Deer River as it winds its way over 100 miles (163 kilometers) southward from Drumheller, you will come upon Dinosaur Provincial Park.1 The park with its dinosaur research station, labs, and outdoor dinosaur exhibits is, like Drumheller, set within the spectacular Red Deer River badlands. Whether you are a paleontologist or a “dino” tourist, the Dinosaur Provincial Park will exceed your greatest expectations and impress you with its extraordinarily rich record of dinosaurs and the world they roamed in. This is why the Park was designated by UNESCO as a World Heritage Site.
