Harmonic Tourism Theoretical and Methodological Model: Application to the Central Highlands of Mexico [PDF]

open access: yes, 2018
The aim of this paper is to present a case of the application of the Theoretical and Methodological Model for Harmonic Tourism, proposed by Palmas et al, (2014), in order to carry out tourism-based planning tasks through the interaction of communities ...

Temporal constraints influence reproductive characteristics that are related to the pace‐of‐life continuum in geese

open access: yesIbis, Volume 166, Issue 3, Page 844-856, July 2024.
Among avian species, particularly those with altricial young, life‐history strategies are characterized by a ‘slow’ pace‐of‐life at lower latitudes, where relatively low annual investments in reproduction are traded‐off for increased survival. Evidence for this pattern in precocial species, however, is equivocal, and questions about ecological drivers ...

The application of ERTS imagery to mapping snow cover in the western United States [PDF]

open access: yes
The author has identified the following significant results. In much of the western United States a large part of the utilized water comes from accumulated mountain snowpacks; thus, accurate measurements of snow distributions are required for input to ...

Microbial Ecology and Site Characteristics Underlie Differences in Salinity‐Methane Relationships in Coastal Wetlands

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 129, Issue 6, June 2024.
Abstract Methane (CH4) is a potent greenhouse gas emitted by archaea in anaerobic environments such as wetland soils. Tidal freshwater wetlands are predicted to become increasingly saline as sea levels rise due to climate change. Previous work has shown that increases in salinity generally decrease CH4 emissions, but with considerable variation ...

Genetic structure of California's elk: a legacy of extirpations, reintroductions, population expansions, and admixture

open access: yesThe Journal of Wildlife Management, Volume 88, Issue 3, April 2024.
California is home to 3 subspecies of North American elk. To obtain a baseline understanding of each subspecies' range, admixture zones, and geographic patterns of genetic diversity, we genotyped 1,271 individual elk from the western United States at 19 microsatellite loci.

Local precision nets for monitoring movements of faults and large engineering structures [PDF]

open access: yes
Along Bocono Fault were installed local high precision geodetic nets to observe the possible horizontal crustal deformations and movements. In the fault area there are few big structures which are also included in the mentioned investigation. In the near
