Ecology of bryophytes along altitudinal and latitudinal gradients in Chile [PDF]

open access: yes, 2002
The bryophyte vegetation in twenty-eight hectare plots in forests of S-Chile between 38° and 42°S and sea level and the forest line has been studied. Since bryophytes are fully dependend on atmospheric water and nutrient supply, they are good indicators ...

Vegetation responses to past volcanic disturbances at the Araucaria araucana forest‐steppe ecotone in northern Patagonia

open access: yesEcology and Evolution, 2022
Volcanic eruptions play an important role in vegetation dynamics and its historical range of variability. However, large events are infrequent and eruptions with a significant imprint in today's vegetation occurred far in the past, limiting our ...

Diameter Increment Modeling in an Araucaria Forest Fragment Using Cluster Analysis [PDF]

open access: yesFloresta e Ambiente, 2018
ABSTRACT The aims of the present study were to test the hypothesis that data stratification by cluster analysis and the use of other variables, in addition to DBH, can improve the precision of the estimates in diametric increment modeling for Mixed Ombrophilous Forest species. The study was carried out in the Irati National Forest.

Species richness, composition, and dominance of core and climate relicts of African miombo woodlands

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract The miombo woodlands, which span about 10% of the African continent, are essential for the ecosystem services they provide. These woodlands are mainly dominated by the genera Julbernardia, Isoberlinia, and Brachystegia. However, there is limited understanding of how species dominance and richness change in relict sites, which are far removed ...

Aerial sketchmapping for monitoring forest conditions in Southern Brazil. [PDF]

open access: yes, 2015
Aerial sketchmapping is a simple, low cost remote sensing method used for detection and mapping of forest damage caused by biotic agents (insects, pathogens and other pests) and abiotic agents (wind, fire, storms, hurricane, ice storms) in North America.
