(BOTANICAL SOC AMER INC, 2006-07)Concerted changes in flower morphology and pollinators provide strong evidence on adaptive evolution. Schizanthus (Solanaccae) has zygomorphic flowers and consists of 12 species of annual or biennial herbs that are distributed ...
-
(2011)The study of multi-modal communication has only recently been extended to innate and learned interactions between flowers and their animal visitors, and usually only to pollinators. Here we studied the relevance of floral ...

(Ediciones Universidad de La Serena, 2006)
-
(SPRINGER, 2005-03)Soil nutrient availability directly enhances vegetative growth, flowering, and fruiting in alpine ecosystems. However, the impacts of nutrient addition on pollinator visitation, which could affect seed output indirectly, ...
-
(Academia Chilena de Ciencias, 2005)
-
(2007)Geo-referenced archive databases on mountain organisms are very promising tools for achieving a better understanding of mountain biodiversity and predicting its changes. The Global Mountain Biodiversity Assessment (GMBA) ...
-
(WILEY-BLACKWELL, 2010-03-02)Understanding disease distributions is of fundamental and applied importance, yet few studies benefit from integrating broad sampling with ecological and phylogenetic data. Here, anther-smut disease, caused by the fungus ...
-
(2004)Aim: Floristic blocks and areas of endemism resulting from a parsimony analysis of endemicity (PAE) using raw floristic data versus data generated from distributional modelling for 130 species in the genus Senecio Tourn. ...
-
(Ecological Society of America, 2004)t. Understanding the factors affecting parasite aggregation in natural host pop- ulations is one of the central questions in parasite ecology. While different biological mechanisms giving rise to aggregation have been ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2006-09)Unfavorable temperatures and weather conditions for biotic pollination in above-tree-line alpine habitats predict self-compatibility, high levels of autogamy and small flower size ("autogamy reproductive assurance hypothesis"), ...
-
(PeerJ Inc., 2018)Several studies have demonstrated the contribution of northern immigrants to the flora of the tropical Andes-the world's richest and most diverse biodiversity hotspot. However, much less is known about the biogeographic ...
-
(MDPI, 2020)Rising temperatures and increasing drought in Mediterranean-type climate areas are expected to affect plant-pollinator interactions, especially in plant species with specialised pollination. Central Chile experienced a ...
-
(Frontiers Media, 2018-07-03)Despite decades of broad interest in global patterns of biodiversity, little attention has been given to understanding the remarkable levels of plant diversity present in the world's five Mediterranean-type climate (MTC) ...
-
(EDICIONES UNIV, CONCEPCION, COMITE DE PUBLICACION, 2008)Se reporta la presencia de Xylocopa splendidula para Santiago, Chile. En Marzo de 2007, hembras fueron observadas nidificando en Acacia dealbata Link y entre diciembre 2007 y febrero 2008 fueron observadas forrajeando ...
-
(Swiss Botanical Society, 2012-11-20)In the alpine life-zone, increasingly slower and unpredictable pollination at the higher altitudes predict an increase in floral investment in strongly outcrossing, pollenlimited biotically pollinated plant species, but ...
-
(Oxford university press, 2017)Low pollinator visitation in harsh environments may lead to pollen limitation which can threaten population persistence. Consequently, avoidance of pollen limitation is expected in outcrossing species subjected to habitually ...
-
(1990)Controlled hand self- and cross-pollination and emasculations were performed on Ourisia poeppigii Benth. (Scrophulariaceae) from the Chilean Patagonia. Ourisia poeppigii is highly self-compatible and strongly autogamous. ...
-
(2002)Endemic taxa are those restricted to a specific area, and could be defined as the exclusive biodiversity of a region. An area of endemism contains taxa found nowhere else and could be catalogued as irreplaceable and of ...
