About 12 miles to the northeast of Carrizozo lies the “ghost town” of White Oaks. This once thriving mining community rests in a small valley surrounded by three wrinkled and rounded mountain peaks: the remains of a ancient cluster of laccoliths (see attached Figure 1). To the northwest lies Lone Mountain with its associated peak, Baxter Mountain, while to the southeast lies Patos Mountain and ...

STUDY OBJECTIVE Acute mountain sickness occurs in more than 25% of the tens of millions of people who travel to high altitude each year. Previous studies on chemoprophylaxis with nonsteroidal anti-inflammatory drugs are limited in their ability to determine efficacy. We compare ibuprofen versus placebo in the prevention of acute mountain sickness incidence and severity on ascent from low to hig...

Both habitat patch size and structure affect the abundance and occurrence of species and thereby can affect the ecology and evolution of species interactions. Here we contrast the level of seed predation and selection exerted by Common Crossbills (Loxia curvirostra complex) and red squirrels (Sciurus vulgaris) in the extensive mountain pine (Pinus uncinata) forests in the Pyrenees with their le...

We present vertical velocity results for the continuous GPS network located in the region of Yucca Mountain, southern Nevada. Based on local and regional tectonics, we hypothesize that vertical velocities at Yucca Mountain are likely to be very small. Data from the network, from May 1999 to January 2003, was processed using the GIPSY-OASIS II software, with ambiguities resolved on a line-by-lin...

The Brazilian mountain ranges from the Guiana Shield highlands are largely unexplored, with an understudied herpetofauna. Here the amphibian and reptile species diversity of the remote Serra da Mocidade mountain range, located in extreme northern Brazil, is reported upon, and biogeographical affinities and taxonomic highlights are discussed. A 22-days expedition to this mountain range was under...

OBJECTIVE To assess the effect of a single aeroallergen on Internet search activity in 3 distinct geographic regions over time. STUDY DESIGN A retrospective time series analysis. SETTING Tertiary academic medical center. METHODS Mountain Cedar pollen counts spanning the periods from 2011 to 2014 were collected for San Antonio, Dallas-Ft Worth, and Houston metro regions (Texas). Google sea...

We used count surveys and mist-net captures to compare habitat associations, relative abundance, species richness, and community similarity of migrant landbirds among four major habitats in the Boise Foothills of southwestern Idaho. Count surveys were conducted from August through October 1997–2000 in conifer forest, mountain shrubland, shrubsteppe, and riparian shrubland. We compared bird dete...

Mountain systems are very diverse and so is the pattern of natural hazards. Worldwide disaster databases show that associated human and economic losses are significant but vary greatly between and within mountain regions. Continued changes in climate, land use and socio-economic conditions are likely to lead to vastly altered mountain landscapes in the future, with associated implications for h...

Mountain biking is an increasingly popular leisure pursuit. Consequences are trail degradation and conflicts with hikers and other users. Resource managers often attempt to resolve these problems by closing trails to mountain biking. In order to estimate the impact of these developments, a model has been devised that predicts the effects of changes in trail characteristics and introduction of a...

Methods Data on species composition for both taxonomic groups were collecting using standard inventory methods for birds and butterflies in temperate regions. Data were compiled at three sampling grains, sites (average 12 ha), canyons (average 74 ha) and mountain ranges. For each sampling grain in turn, we calculated similarity of species composition using the Jaccard index. First, we investiga...
