Local topography increasingly influences the mass balance of a retreating cirque glacier [PDF]

open access: yesThe Cryosphere, 2018
Local topographically driven processes – such as wind drifting, avalanching, and shading – are known to alter the relationship between the mass balance of small cirque glaciers and regional climate.

Thinning of the Monte Perdido Glacier in the Spanish Pyrenees since 1981 [PDF]

open access: yes, 2016
Producción CientíficaThis paper analyzes the evolution of the Monte Perdido Glacier, the third largest glacier in the Pyrenees, from 1981 to the present. We assessed the evolution of the glacier's surface area by analysis of aerial photographs from 1981,

The Melting ‘Crown of the Continent’: Visual History of Glacier National Park [PDF]

open access: yes, 2018
Glacier National Park (GNP), located in northwest Montana, US, was signed into existence on 11 May 1910 by then President William Howard Taft. Conservationist George Bird Grinnell was instrumental in lobbying for the park’s creation and negotiated the ...

Mountain goat declines in a protected, interior, native population

open access: yesEcosphere
A shifting climate poses threats to alpine‐adapted species including mountain goats. We used long‐term (12 years) citizen science monitoring data and Bayesian N‐mixture modeling to estimate population trends and drivers of population metrics among ...

Alpine plant community diversity in species–area relations at fine scale

open access: yesArctic, Antarctic, and Alpine Research, 2020
Observations of diversity in alpine vegetation appear to be scale dependent. The relations of plant species richness with surface processes and geomorphology have been studied, but patterns of beta diversity are less known.

Deep coral habitats of Glacier Bay National Park and Preserve, Alaska.

open access: yesPLoS ONE, 2020
Glacier Bay National Park and Preserve (GBNPP) in Southeast Alaska is a system of glaciated fjords with a unique and recent history of deglaciation. As such, it can serve as a natural laboratory for studying patterns of distribution in marine communities

Enhanced regional connectivity between western North American national parks will increase persistence of mammal species diversity

open access: yesScientific Reports, 2023
Many protected areas worldwide increasingly resemble habitat isolates embedded in human-modified landscapes. However, establishing linkages among protected areas could significantly reduce species-loss rates.

Differentiating Science from Opinion [PDF]

open access: yes, 2012
This small collection of teaching activities and discussion prompts seeks to convey to students the difference between legitimate debate regarding climate change and debate which is meant to sway public opinion to protect lucrative industries.

Marine Benthic Habitat Mapping of Muir Inlet, Glacier Bay National Park and Preserve, Alaska With an Evaluation of the Coastal and Marine Ecological Classification Standard III [PDF]

open access: yes, 2010
Seafloor geology and potential benthic habitats were mapped in Muir Inlet, Glacier Bay National Park and Preserve, Alaska, using multibeam sonar, ground-truth information, and geological interpretations. Muir Inlet is a recently deglaciated fjord that is

The use of chronosequences in studies of ecological succession and soil development [PDF]

open access: yes, 2010
1. Chronosequences and associated space-for-time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time-scales.
