Heine Fuster, Inger; Vega Retter, Caren; Sabat Kirkwood, Alejandro Pablo; Ramos Jiliberto, Rodrigo (Oxford University Press, 2010)Daphnia exilis is a halophylic species that was recently found in Chile, distant from its natural range. In this study, we analyze the osmoregulatory and life-history responses to salinity exhibited by Daphnia exilis, ...

Ramos Jiliberto, Rodrigo; Frodden, Ernesto; Aránguiz Acuña, Adriana (Elsevier, 2007)It has been reported that, in order to reduce mortality, prey are able to change their phenotype in response to cues released from predators. These short-time responses constitute effective antipredator strategies in ...
-
Ramos Jiliberto, Rodrigo; Garay Narváez, Leslie (2007)By means of qualitative techniques we analyze the consequences of inducible defenses of species embedded in trophic chains on the community stability and responses of population equilibrium densities to press perturbations. ...
-
Ramos Jiliberto, Rodrigo (ELSEVIER SCI LTD, 2005-01)In the search for a unified basis for constructing food-web models, the long-standing discrepancy between biomass conversion (BC) and individual survival (IS) modeling has been revitalized by Ginzburg (J. Anim. Ecol. 67 ...

Ramos Jiliberto, Rodrigo; Garay Narváez, Leslie; Medina, Matías H. (Springer, 2012)The coast of Chañaral Bay in northern Chile has been affected by copper mine wastes for decades. This sustained perturbation has disrupted the intertidal community in several ways, but the mechanisms behind the ...

Ramos Jiliberto, Rodrigo; Mena Lorca, Jaime; Flores, José D.; Morales Alvarez, Waldo (ELSEVIER SCIENCE BV, 2008-06)Inducible defenses are a form of phenotypic plasticity that potentially modify direct interactions between various members of an ecological community, generating traitmediated indirect effects. In this work, the hypothesis ...

Valdovinos, Fernanda S.; Berlow, Eric L.; Moisset de Espanes, Pablo; Ramos-Jiliberto, Rodrigo; Vázquez, Diego P.; Martínez, Neo D. (2018-05-31)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ...

Ramos Jiliberto, Rodrigo; Domínguez, Daniela; Espinoza, Claudia; López, Gioconda; Valdovinos, Fernanda S.; Bustamante Araya, Ramiro; Medel Contreras, Rodrigo (ELSEVIER, 2010)Pollination interaction networks exhibit structural regularities across a wide range of natural environments. Long-tailed degree distribution, nestedness, and modularity are the most prevalent topological patterns found ...
-
Dambacher, Jeffrey M.; Ramos Jiliberto, Rodrigo (University of Chicago, 2007-09)Models of ecological communities are traditionally based on relationships between pairs of species, where the strengths of per capita interactions are fixed and independent of population abundance. A growing body of ...

Ebensperger, Luis A.; Hurtado, María José; Ramos Jiliberto, Rodrigo (BLACKWELL, 2006-09)Individuals of social and partially social species typically reduce their vigilance activity when foraging in groups. As a result, per capita risk of predation decreases and individuals allocate more time to foraging and ...
