Population genetics of the endangered Crowned Solitary Eagle (Buteogallus coronatus) in South America
(Springer, 2016-08)
The Crowned Solitary Eagle (Buteogallus coronatus) is one of the rarest and most severely threatened birds of prey in the Neotropical region. We studied levels of neutral genetic diversity, population structure, and the ...
Which pixel is a forest? Tree crown delineation using VHR images to estimate tree cover in landsat based classification
(IEEE Geoscience and Remote Sensing Society, 2021-07-12)
Determining the percentage of tree crown cover is extremely important to establish in advance which forest types can be classified with high resolution sensors such as Landsat. This paper describes the determination of a ...
Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests.
(EDP Sciences, 2011-04)
Introduction Silviculture systems applied in Nothofaguspumilio forests are based on opening the canopy tostimulate natural regeneration by modifying light and soilmoisture. The objective is to evaluate regeneration dynamicsof ...
Ten years of seed production and establishment of regeneration measurements in Nothofagus antarctica forests under different crown cover and quality sites, in Southern Patagonia
(Springer, 2018-06)
This study evaluated the seed production and quality and the subsequent regeneration establishment in five pure Nothofagus antarctica forests growing at different site qualities and crown cover during 10 years, in Southern ...
Resolving uncertainties in predictive equations for urban tree crown characteristics of the southeastern United States: Local and general equations for common and widespread species
Urban forest research and management requires improved methods for quantifying ecosystem structure and function. Regional equations for urban tree crown width and height can accordingly improve predictions of urban tree ...
