Bustamante Araya, Ramiro; Quiñones Cortés, Daniela; Duarte Muñoz, Milen; Goncalves Amador, Estefany; Cavieres, Lohengrin A. (MDPI, 2022)To understand the factors that limit invasive expansion in alien species, it is critical to predict potential zones of colonization. Climatic niche can be an important way to predict the potential distribution of alien ...

Cavieres, Lohengrin A.; Chacón, Paulina; Peñaloza, Alejandro; Molina Montenegro, Marco A.; Arroyo, Mary T. K. (SPRINGER, 2007-05)Leaf litter accumulation can have either positive, negative or neutral effects on seed germination and seedling recruitment. In montane woodlands of the Mediterranean zone of central Chile, large amounts of leaf litter ...

Cavieres, Lohengrin A.; Badano, Ernesto I.; Sierra Almeida, Angela; Molina Montenegro, Marco A. (INST ARCTIC ALPINE RES, UNIV COLORADO, 2007-05)Cushion plants are one of the most common growth forms in alpine habitats. Their low stature, dense canopy, and compact form allow them to decouple their microclimate from the surrounding environment, mitigating the effect ...

Muñoz, Alejandro A.; Cavieres, Lohengrin A. (OXFORD UNIV PRESS, 2006-07)Background and Aims Post-dispersal seed predation in alpine communities has received little attention despite evidence that seeds removed by granivores can decrease plant recruitment into ecosystems. Moreover, few studies ...

Acuña Rodríguez, Ian S.; Cavieres, Lohengrin A.; Gianoli, Ernesto (SOCIEDAD BIOLOGIA CHILE, 2006-09)Nurse effects, which occur when one plant species enhances the survival or growth of another plant species, are predicted to be most relevant in stressful environments. These effects are particulary important during seedling ...

Casanova Katny, M. Angélica; Bravo, León A.; Molina Montenegro, Marco A.; Corcuera, Luis J.; Cavieres, Lohengrin A. (SOCIEDAD BIOLGIA CHILE, 2006-03)Photosynthesis of Colobanthus quitensis and mesoclimatic conditions of air temperature and light intensity during the growing season were investigated at 2,650 in ill the central Chilean Andes. Oil three typical days of ...

Pauchard, Aníbal; García, Rafael; Peña, Eduardo; Bustamante Araya, Ramiro; González, Cristián; Cavieres, Lohengrin A. (SPRINGER, 2008-04)Invasive species can increase fire frequency and intensity, generating favorable conditions for their self-perpetuation. Mediterranean south-central Chile may be especially prone to the effects of invasive species on fire ...

Cavieres, Lohengrin A.; Badano, Ernesto I.; Sierra Almeida, Angela; Gómez González, Susana; Molina Montenegro, Marco A. (BLACKWELL, 2006-01)In alpine habitats, positive interactions among plants tend to increase with elevation as a result of altitudinal increase in environmental harshness. However, in mountains located in arid zones, lower elevations are also ...

Arroyo, Mary T. K.; Chacón, Paulina; Cavieres, Lohengrin A. (OXFORD UNIV PRESS, 2006-09)center dot Background and Aims Broad surveys have detected inverse relationships between seed and adult longevity and between seed size and adult longevity. However, low and unpredictable precipitation is also associated ...

Badano, Ernesto I.; Cavieres, Lohengrin A.; Molina Montenegro, Marco A.; Quiroz, C. L. (ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2005-07)The most important processes shaping communities are likely to leave observable imprints on their spatial structure. The net outcome of positive and negative interactions among plants has been proposed to vary inversely ...

Goncalves Amador, Estefany Javiela; Herrera, Ileana; Alexander, Jake; Duarte, Milen; Cavieres, Lohengrin A.; Morales Salinas, Luis José Alejandro; Bustamante Araya, Ramiro Osciel (MDPI, 2022)Alien plant species are colonizing high-elevation areas along roadsides. In this study, we evaluated whether the distributions of alien plants in the central Chilean mountains have reached climatic equilibrium (i.e., upper ...
