(2002)Santuario de la Naturaleza Yerba Loca (SN Yerba Loca), Metropolitan Region (MR), 33° S, Chile is analyzed for its conservation value and efficiency in protecting native vascular plants in a regional context. The reserve's ...
-
(Universidad de Chile, 2006)Richness and composition floristical characters of the high-andean vegetation were evaluated among a site in the Coastal (Altos de Chicauma) and Andes (Quilapilún) mountain ranges of central Chile (33º S). The dispersal ...
-
(1993)The frequency of dioecy in the predominantly biotically‐pollinated native flora of a temperate montane sclerophyllous forest in central Chile, 33oS, is determined. Experimental crosses and other tests were performed on a ...
-
(2010)It has been argued that trichromatic bees with photoreceptor spectral sensitivity peaks in the ultraviolet (UV), blue and green areas of the spectrum are blind to long wavelengths (red to humans South American temperate ...
-
(2007)Insect pollinator activity can be influenced by biotic (e.g., patch floral density and floral display) or by abiotic factors (e.g., temperature, wind velocity, cloudiness). In spite of microsite, seasonal and interannual ...
-
(2007)In our study, we asked whether butterflies visiting Chaetanthera lycopodioides (Asteraceae) in the subnival at 3450 m a.s.l. in the central Andes prefer larger floral displays. To answer this question, we compared the ...
-
(1997)In the Andes of Central Chile, flowering commences 1-2 months earlier on equatorial-(north-) facing than on polar- (south-) facing slopes, and pollinator assemblages also differ between these habitats. In order to understand ...
-
(Universidad de Chile, 2017-07)La pérdida de frugívoros a nivel mundial representa una seria amenaza para la persistencia de las plantas, ya que las interacciones dispersor-planta son fundamentales para la reproducción de estas últimas. Sin embargo, en ...
-
(PNAS, 2013-07)The assembly of regional biotas and organismal responses to anthropogenic climate change both depend on the capacity of organisms to adapt to novel ecological conditions. Here we demonstrate the concept of evolutionary ...
-
(MDPI, 2021)Delayed flowering due to later snowmelt and colder temperatures at higher elevations in the alpine are expected to lead to flowering phenological adjustment to prevent decoupling of peak flowering from the warmest time of ...
-
(Wiley, 2021)The establishment of species boundaries has been a difficult task for biologists since the beginning of classifications. Within South American Allioideae (= Alliaceae), the delimitation of genera and species has long been ...
-
(Royal Soc., 2015)Orchids are the most diverse family of angiosperms, with over 25 000 species, more than mammals, birds and reptiles combined. Tests of hypotheses to account for such diversity have been stymied by the lack of a fully ...
-
(Blackwell, 2019)How animal-pollinated plants support low and stochastic pollination in the high alpine is a key question in plant ecology. The ovule bet-hedging hypothesis proposes compensation for stochastic pollination via ovule oversupply ...

-
(2012)The southern Andean clade of Valeriana provides an excellent model for the study of biogeography. Here we provide new data to help clarify phylogenetic relationships among the South American valerians, with special focus ...
-
(2006)Low temperatures, short growing seasons, and strong winds, which constrain the abundance and activity of insect pollinators, characterize alpine ecosystems. In northern hemisphere alpine environments, the reproductive ...
-
(Ecological Society of America, 2003)Mimulus luteus (Scrophulariaceae) is a perennial herb occurring in the South American Andes that shows a wide variation in the size and shape of a red spot on the lower lobe of the yellow flower. We describe the preference ...
