The dynamics of natural populations: feedback structures in fluctuating environments

Good regulations, bad regulation: a Peruvian port case
(Universidad del Pacífico. Centro de InvestigaciónPerú, 2012-08)
Lead poisoning of Callao’s population is the most severe externality port operations cause in Peru. The problem could have been tackled in 2009, after the government issued a decree regulating how mineral ore was to be ...
Density but not climate affects the population growth rate of guanacos (Lama guanicoe) (Artiodactyla, Camelidae)
(F1000Research, 2014-10)
We analyzed the effects of population density and climatic variables on the rate of population growth in the guanaco (Lama guanicoe), a wild camelid species in South America. We used a time series of 36 years (1977-2012) ...
Population regulation in Magellanic penguins: what determines changes in colony size?
(Public Library of Science, 2015-03-18)
Seabirds are often studied at individual colonies, but the confounding effects of emigration and mortality processes in open populations may lead to inappropriate conclusions on the mechanisms underlying population changes. ...
Phenotypic plasticity in clutch size regulation among populations of a potential invasive fruit fly from environments that vary in host heterogeneity and isolation
(Cambridge University Press, 2018-05)
Phenotypic plasticity is thought to evolve in response to environmental unpredictability and can shield genotypes from selection. However, selection can also act on plastic traits. Egg-laying behaviour, including clutch ...
Bayesian inference on the effect of density dependence and weather on a guanaco population from Chile
(Public Library Of Science, 2014-12)
Understanding the mechanisms that drive population dynamics is fundamental for management of wild populations. The guanaco (Lama guanicoe) is one of two wild camelid species in South America. We evaluated the effects of ...
Anger and regulation
(Universidad de Montevideo, Facultad de Ciencias Empresariales y Economía, Departamento de Economía, 2012)
We study a model where agents experience anger when they see a firm that hasdisplayed insufficient concern for their clients' welfare (altruism) makes high profits.Regulation can increase welfare, for example, through fines ...
