Accounting for relatedness and spatial structure to improve plant phenotypic selection in the wild (Springer, 2020)Identifying natural selection in wild plant populations is a challenging task, as the reliability of selection coefficients depends, among other factors, on the critical assumption of data independence. While rarely examined, ...
-
(2013)The impacts of exotic plants on the pollination and reproductive success of natives have been widely reported; however, in spite of its importance for the invasive process, the role of native plants in the pollination and ...
-
(Springer, 2013-06-18)The arrival of exotic pollinators to new habitats may introduce new patterns of floral preference and foraging behavior that modify the structure of the resident plant-pollinator community. The aim of this paper is to ...
-
(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 ...
-
(Ecological Society of America, 2000)A two-year field study was conducted to evaluate the potential of two cactus species, Echinopsis chilensis and Eulychnia acida, to evolve defensive traits against the parasitic mistletoe Tristerix aphyllus (Loranthaceae). ...
-
(Public Library Science, 2016)Herbivory has been long considered an important component of plant-animal interactions that influences the success of invasive species in novel habitats. One of the most important hypotheses linking herbivory and invasion ...
-
Ecology and evolution of negative and positive interactions in Cactaceae: Lessons and pending tasks (2012)Background: The Cactaceae is a diverse and conspicuous Neotropical family that has evolved a wide variety of adaptations during co-evolution with their interacting species. Recent research has indicated complex ecological ...
-
(Wiley, 2012)Plant-animal interaction networks provide important information on community organization. One of the most critical assumptions of network analysis is that the observed interaction patterns constitute an adequate sample ...
-
(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 ...
-
(2011)The rate of pollen exchange within and among flowers may depend on pollinator attraction traits such as floral display size and flowering plant density. Variations in these traits may influence pollinator movements, pollen ...
-
(2011)Floral damage can reduce flower attractiveness for pollinator service. However, the reproductive impact of flower herbivory may be contingent on a petal that is damaged. Flowers having nectar guides are expected to suffer ...
-
(Nature Publishing Group, 2017)© 2017 The Author(s). Plant-animal interactions are strong drivers of phenotypic evolution. However, the extent to which anthropogenic habitat transformation creates new selective scenarios for plant-animal interactions ...
-
(Wiley, 2019)The global increase in the proportion of land cultivated with pollinator-dependent crops implies increased reliance on pollination services. Yet agricultural practices themselves can profoundly affect pollinator supply and ...
-
(2016)Background: The presence of exotic plants increases the heterospecific pollen (HP hereafter) received by native plants and reduces their reproductive output. Aims: We assessed whether the exotic herb Echium vulgare ...
-
(Ecological Society of America, 2017)© 2017 Fontúrbel et al. Anthropogenic disturbance can modify habitat structure and resource availability, potentially disrupting ecological interactions. This issue may be critical for pollination and seed dispersal, which ...
-
(2002)Apparent competition occurs when species that otherwise may not directly interact still exhibit negative indirect effects on one another because they share a food-limited predator (enemy). Even though this type of indirect ...
-
(Wiley, 2014)Parasitic plants often have a strong fitness-impact on their plant hosts through increased host mortality and reduced or complete suppression of reproduction. Tristerix corymbosus (Loranthaceae) is a hemiparasitic mistletoe ...
-
(2004)Most studies assessing the importance of developmental instability of floral characters for pollinator visits and plant fitness have focused on the fluctuating asymmetry (FA) of the corolla phenotype. The importance of ...
-
(Universidad de Concepcion, 2011)We report some aspects of the floral biology of Echinopsis chiloensis ssp. chiloensis in a population near to the northern limit of its distribution. Anthesis is strictly diurnal and flowers remain open during 492 min on ...
-
(2007)Most studies on the fitness advantage of outbreeding in host-parasite systems have been assessed from the host rather than the parasite perspective. Here, we performed experimental pollination treatments to evaluate the ...
