Canopy structure analysis for estimating forest regeneration dynamics and growth in Nothofagus pumilio forests
(Springer, 2011-04-08)
Introduction Silviculture systems applied in Nothofagus pumilio forests are based on opening the canopy to stimulate natural regeneration by modifying light and soil moisture. The objective is to evaluate regeneration ...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
(Copernicus Publications, 2009)
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing crop fine root mass ...
Calidad de planta y comportamiento morfológico de Cedrela fissilis Vell. en respuesta a distintos sistemas de producción y sustratos en vivero = Plant quality and morphological behavior of Cedrela fissilis Vell. in response to different production systems and nursery substrates
(Facultad de Ciencias Forestales, Universidad Nacional de Santiago del Estero, 2020-12)
Cedrela fissilis Vell. es una especie autóctona de la Selva Misionera, incluida actualmente en la categoría en peligro de la Lista Roja de especies amenazadas y en el actual marco legal forestal argentino surgió como ...
Contenidos de materia orgánica y condición física de un Kandiudult de Misiones bajo diferentes sistemas de preparación del terreno forestal y bosque nativo
(Facultad de Agronomía, Universidad de Buenos Aires, 2013-08)
Las propiedades físicas de los suelos de ambientes subtropicales húmedos fueron tradicionalmente menos estudiadas que los de zonas templadas. Una característica de los primeros es su menor resiliencia frente a un disturbio. ...
Deep soil: Quantification, modeling, and significance of subsurface nitrogen
(2015-01-05)
Nitrogen (N) is one of the primary limiting nutrients in Pacific Northwest forests, as well as many other terrestrial ecosystems around the world. Efforts to quantify total soil N and to monitor N cycling have often sampled ...
Carbon accumulation along a stand development sequence of Nothofagus antarctica forests across a gradient in site quality in Southern Patagonia
(Elsevier, 2010-06-25)
Above- and below-ground C pools were measured in pure even-aged stands of Nothofagus antarctica (Forster f.) Oersted at different ages (5–220 years), crown and site classes in the Patagonian region. Mean tissue C concentration ...
Carbon (δ13C) and nitrogen (δ15N) stable isotope composition in plant and soil in Southern Patagonia’s native forests.
(Wiley, 2012-01)
Stable isotope natural abundance measurements integrate across several biogeochemical processes in ecosystem N and C dynamics. Here, we report trends in natural isotope abundance (d13C and d15N in plant and soil) along a ...
Spatial and seasonal variation in niche partitioning between blue manakin (Chiroxiphia caudata) and greenish schiffornis (Schiffornis virescens) in southeastern Brazil
(Taylor & Francis LtdAbingdonInglaterra, 2009)
