(Elsevier, 2011)Many organisms exhibit ontogenetic shifts in their diet and habitat use, which often exert a large influence on the structure and expected dynamics of food webs and ecological communities. Nevertheless, reliable methods ...
-
(ELSEVIER SCIENCE BV, 2010-09-06)Intraguild predation constitutes a widespread interaction occurring across different taxa, trophic positions and ecosystems, and its endogenous dynamical properties have been shown to affect the abundance and persistence ...
-
(SOC BIOLGIA CHILE, 2009-12-17)Trabajos tempranos basados en la teoría de Sistemas Dinámicos, demostraron que mientras mayor sea el número de poblaciones en interacción ecológica, el sistema tiende a ser más inestable. Sin embargo, la evidencia ...
-
(2010)1. A key aspect of the ecology and evolution of adaptive prey responses to predator risk is the timing by which the former develop a defensive trait in response to inducing signals released by the latter. This property, ...
-
(Ecological Society of Australia, 2007)In this work we report on the seasonal trends of abundances in terms of temperature exposure for four coexisting cladoceran species (Daphnia ambigua (Daphniidae), Ceriodaphnia dubia (Daphniidae), Diaphanosoma chilense ...
-
(WILEY-BLACKWELL, 2010-09-13)Species coexistence within ecosystems and the stability of patterns of temporal changes in population sizes are central topics in ecological theory. In the last decade, adaptive behaviour has been proposed as a mechanism ...
-
(2013)This work deals with some typographical mistakes into the above-referenced paper. Although they do not affect the main results, it is necessary to make due corrections. We affirm that the results and conclusions obtained ...
-
(SOCIEDAD BIOLOGIA CHILE, 2004-03)In this work we analyzed the depth-distribution, at noon and midnight, of three zooplankton populations which are common inhabitants of lakes from central Chile and coexist in lake El Plateado. The species were Tumeodiaptomus ...
-
(ELSEVIER, 2008-06-24)Inducible defenses influence the dynamics of both the prey exhibiting the response and its predator, but it could affect indirectly other populations in the community. Earlier studies concerned with population dynamics of ...
-
(Frontiers Media, 2021)Social policies are commonly defined from scattered knowledge. It is hard to find examples of social policy design based on a systemic perspective, and even harder with formal modeling support. To advance in filling this ...
-
(Oxford University Press, 2011)Theoretical predictions suggest that adaptive phenotypic plasticity, and induced defenses in particular, exert a stabilizing effect on ecological systems and increase the likelihood of species coexistence. Nonetheless, ...
-
(Sociedad de Biología de Chile, 2008-06)During the last decades, limnological studies on Chilean systems have contributed to know the species composition and main environmental variables of many water bodies distributed over a wide latitudinal interval, from ...
-
(Public Library Science, 2020)Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ...
-
(OXFORD UNIV PRESS, 2008-10)Studies of planktonic organisms have shown that various life-history traits, and consequently population growth rate, can be affected by chemical cues released by high densities of conspecifics. In this work we test for ...
-
(2009)In nature, prey and predator species are embedded in complex networks of ecological interactions. As a consequence, organism level reactions such as predator-induced prey defenses will not only influence the dynamics of ...
-
(ELSEVIER SCIENCE BV, 2008-04-20)strong indicators of a changing replacement dynamics in the community. Stationary Markov chain models predict that the future tree composition such Maulino forest fragments will differ from that of continuous, intact ...
-
(Nordic Society Oikos, 2013)Human activities have led to massive influxes of pollutants, degrading the habitat of species and simplifying their biodiversity. However, the interaction between food web complexity, pollution and stability is still ...
-
(Wiley-Blackwell, 2016)Much research debates whether properties of ecological networks such as nestedness and connectance stabilise biological communities while ignoring key behavioural aspects of organisms within these networks. Here, we ...
-
(BLACKWELL, 2008-09)1. Here, we report morphological and life-historical changes in the cladoceran Daphnia ambigua in response to chemical cues released by the predatory water mite Piona chilensis. Both species are common inhabitants of ...
-
(Springer, 2016)Interaction strength among species plays a crucial role in shaping the functioning of ecological communities, but it is often assumed to be insensitive to inter-individual variation in underlying parameters such as attack ...
