Effects of habitat fragmentation on seed quality of Lapageria rosea Efecto de la fragmentación del hábitat sobre la calidad de las semillas en Lapageria rosea
(2004)
Habitat fragmentation is commonly associated to a reduction in plant fitness, because the reduction in the number of seeds produced. However habitat fragmentation might also affect plant fitness through a reduction in the ...
Defining corridors for movement of multiple species in a forest-plantation landscape
(Elsevier, 2020)
Forestry plantations of Pinus radiata, managed through clearcutting method, would offer
resistance to the movement of native fauna among remnants of native forest. In this study,
we evaluate the possibilities of establishing ...
Effect of canopy openness on growth, specific leaf area, and survival of tree seedlings in a temperate rainforest of Chiloé Island, Chile
(Taylor & Francis, 2005)
Tree species of intermediate-shade tolerance may regenerate in canopy gaps as well as in the forest understory. However, seedling performance may vary widely between shaded and open habitats. In this study, we assessed the ...
Foraging Behaviour in Magellanic Woodpeckers Is Consistent with a Multi-Scale Assessment of Tree Quality
(Public Library Science, 2016)
Theoretical models predict that animals should make foraging decisions after assessing the quality of available habitat, but most models fail to consider the spatio-temporal scales at which animals perceive habitat ...
Intraspecific differences in metabolic rate of Chroeomys olivaceus (Rodentia: Muridae): the effect of thermal acclimation in arid and mesic habitats
(Sociedad de Biologia de Chile, 2005)
Studies of metabolic capacities in rodents have been largely studied at an inter-specific levels, but physiological capacities of populations belonging to the same species have received lesser attention. Here we studied ...
Change of niche in guanaco (Lama guanicoe): the effects of climate change on habitat suitability and lineage conservatism in Chile
(PEERJ, 2018)
Background: The main goal of this contribution was to define the ecological niche of the guanaco (Lama guanicoe), to describe potential distributional changes, and to assess the relative importance of niche conservatism ...
Between-population differences in digestive flexibility in the olivaceous field mouse
(ELSEVIER GMBH, 2010-08-28)
The flexibility of digestive traits characterizes a standard model of physiological flexibility, demonstrating
that animals adjust their digestive attributes in order to maximize overall energy return. Using an
intraspecific ...
Características de la producción científica de la Revista INVI en la era SciELO, 2009-2016
(University Library System, University of Pittsburgh, 2017)
En este artículo realizamos un análisis socio-demográfico y bibliométrico de Revista INVI, publicación periódica del Instituto de la Vivienda de la Universidad de Chile, basándonos en métodos propios y en la literatura ...
Temporal fluctuation in shrub species preferences of two native rodents: The effect of infection status on habitat use
(Wiley-Blackwell, 2016)
Small mammals use plant species for gathering food resources and for shelter. Preferences for certain plant species are related to nutritional restrictions and behavioural patterns, which could be altered in the presence ...
