Riparian leaf litter processing by benthic macroinvertebrates in a woodland stream of central Chile
(Sociedad de Biología de Chile, 2001)
Effect of a native tree on seedling establishment of two exotic invasive species in a semiarid ecosystem
(2011)
Theory predicts that in more stressful environments, positive plant-plant interactions should be more important than negative ones. For instance, in arid and semiarid regions, amelioration of soil drought produced by the ...
The effects of tree cover and soil nutrient addition on native herbaceous richness in a neotropical savanna
(2021-01-01)
Exotic grasses and high-nutrient availability are common factors that may limit recovery of herbaceous diversity in derived savannas, while tree encroachment is a threat to diversity in old-growth savannas. To understand ...
Exotic species as modifiers of ecosystem processes: Litter decomposition in native and invaded secondary forests of NW Argentina
(Elsevier Masson, 2014-03)
Invasions of exotic tree species can cause profound changes in community composition and structure, and may even cause legacy effect on nutrient cycling via litter production. In this study, we compared leaf litter ...
Large-scale impacts of multiple co-occurring invaders on monkey puzzle forest regeneration, native seed predators and their ecological interactions
(Elsevier, 2016-04)
Most ecosystems of the world are being increasingly invaded by a variety of alien species. However, little is known about the combined ecological impacts of multiple co-occurring invaders. We assessed the impact of a ...
Pricing arithmetic Asian options under the CEV process
(Universidad ESAN. ESAN EdicionesPE, 2010-12-30)
This paper discusses the pricing of arithmetic Asian options when the underlying stock follows the constant elasticity of variance (CEV) process. We build a binomial tree method to estimate the CEV process and use it to ...
