Valor adaptativo de la longitud de la radícula de la planta holoparásita tristerix aphyllus (loranthaceae): detectando causas de selección natural.
(2004)
Phenotypic plasticity is the ability of a genotype to respond to changes in the environment through modifications in the phenotype. This capacity is adaptive in heterogeneous environments if the plastic genotypes show a ...
Assessment of correlational selection on tolerance and resistance traits in a host plant-parasitic plant interaction
(Springer, 2001)
Resistance and tolerance are considered to be different plant strategies against disease. While resistance traits prevent hosts becoming parasitized or reduce the extent of parasitism, tolerance traits reduce the fitness-impact ...
Phenotypic plasticity in the holoparasitic mistletoe Tristerix aphyllus (Loranthaceae): consequences of trait variation for successful establishment
(2007)
The ability of a genotype to respond to changes in the environment through modifications in the phenotype is adaptive when the plastic genotypes attain a higher fitness than non-plastic genotypes. In this study we examine ...
Effects of vector behavior and host resistance on mistletoe aggregation
(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 ...
Conducta sexual de tres poblaciones de Drosophila funebris que vivien naturalmente en distintos sitios de crianza
(Universidad de Chile, 2011)
Para comprender la naturaleza de los primeros eventos que llevan a originar nuevas
especies, se investigaron tres poblaciones alopátricas chilenas de D.funebris, que se crían
en diferentes frutos o tejidos fermentados. ...
Ecología espacial y epidemiólogía del muérdago. Tristerix aphyllus.
(2008)
Los muérdagos son un grupo de angiospermas parásitas epífitas que a diferencia de otros parásitos
no tienen estadios de vida libre y dependen completamente de sus vectores, generalmente aves, para
propagarse. Estos participan ...
