Andean Cloud Forest Tree Lines

open access: yesMountain Research and Development, 2002
Abstract We challenge the paradigm of natural tree line formation in the equatorial Andes with an alternate view that incorporates the human dimension. We present both direct and indirect evidence of anthropogenic influences on cloud forest tree line location; these human influences should be incorporated in definitions of Andean tree lines as (1) the ...

Biodiversity relationships in three structural components in a beech forest of Fagus grandifolia subsp. mexicana

open access: yesBotan‪ical Sciences, 2019
Background: Several studies have called attention to beech forest conservation and restoration in Mexico. Human activities (e.g., logging and grazing) have perturbed the few beech forests that persist in the Sierra Madre Oriental, Mexico. However, basic

Viewing the Forest in 3-D: How Spherical Stereo Videos Enable Low-Cost Reconstruction of Forest Plots

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Understanding and monitoring the surrounding environment increasingly rely on its 3-D representations. However, the often high costs of 3-D data equipment limit its wide usage, and low-cost solutions are in demand. Here, we propose a novel approach based
