Assessing the impact of removal scenarios on population viability of a threatened, long-lived avian scavenger
Margalida, Antoni; Colomer, M. Àngels (Maria Àngels); Oro, Daniel; Arlettaz, Raphaël; Donázar, José A. (Nature Publishing Group, 2015)The removal of eggs or chicks from wild populations to create captive populations, reinforce free-ranging populations or reintroduce species into the wild is a restoration tool that requires an assessment of potential ... -
Behavioral evidence of hunting and foraging techniques by a top predator suggests the importance of scavenging for preadults
Margalida, Antoni; Colomer, M. Àngels (Maria Àngels); Sánchez, Roberto; Sánchez, Francisco Javier; Oria, Javier; González, Luis Mariano (Wiley Online Library, 2017)Scavenging may be a regular feeding behavior for some facultative raptor species oc-cupying low quality habitats and/or with little experience in hunting techniques. However, its importance has been largely ... -
Can wild ungulate carcasses provide enough biomass to maintain avian scavenger populations? An empirical assessment using a bio-inspired computational model
Margalida, Antoni; Colomer, M. Àngels (Maria Àngels); Sanuy i Castells, Delfí (Public Library of Science (PLoS), 2011)Background: The reduction in the amount of food available for European avian scavengers as a consequence of restrictive public health policies is a concern for managers and conservationists. Since 2002, the application of ... -
Carrion ecology modelling for vulture conservation : are vulture restaurants needed to sustain the densest breeding population of the African white-backed vulture?
Kane, Adam; Jackson, Andrew L; Monadjem, Ara; Colomer, M. Àngels (Maria Àngels); Margalida, Antoni (Wiley, 2015)As obligate scavengers, vultures are entirely dependent on carrion resources. In this study we model the carrion ecology of an ecosystem in Swaziland which is home to the densest breeding population of the African White-backed ... -
Improving the peer-review process and editorial quality: key errors escaping the review and editorial process in top scientific journals
Margalida, Antoni; Colomer, M. Àngels (Maria Àngels) (PeerJ, 2016)We apply a novel mistake index to assess trends in the proportion of corrections published between 1993 and 2014 in Nature, Science and PNAS. The index revealed a progressive increase in the proportion of corrections ... -
Modeling of Vaccination and Contact Tracing as Tools to Control the COVID-19 Outbreak in Spain
Colomer, M. Àngels (Maria Àngels); Margalida, Antoni; Alòs, Francesc; Oliva-Vidal, Pilar; Vilella, Anna; Fraile Sauce, Lorenzo José (MDPI, 2021)We developed an agent-based stochastic model, based on P Systems methodology, to decipher the effects of vaccination and contact tracing on the control of COVID-19 outbreak at population level under different control ... -
Modeling the consequences of the demise and potential recovery of a keystone-species: wild rabbits and avian scavengers in Mediterranean landscapes
Cortés-Avizanda, Ainara; Colomer, M. Àngels (Maria Àngels); Margalida, Antoni; Ceballos, Olga; Donázar, José A. (Nature Publishing Group, 2015)Restoration of demised keystone-species populations is an overriding concern in conservation biology. However, since no population is independent of its environment, progress is needed in predicting the efficacy of restoration ... -
Modelling the effects of sanitary policies on European vulture conservation
Margalida, Antoni; Colomer, M. Àngels (Maria Àngels) (Nature Publishing Group, 2012)Biodiversity losses are increasing as a consequence of negative anthropogenic effects on ecosystem dynamics. However, the magnitude and complexity of these effects may still be greatly underestimated. Most Old World ... -
Modelling the SARS-COV-2 outbreak: assessing the usefulness of protective measures to reduce the pandemic at population level
Colomer, M. Àngels (Maria Àngels); Margalida, Antoni; Alòs, Francesc; Oliva-Vidal, Pilar; Vilella, Anna; Fraile Sauce, Lorenzo José (Elsevier, 2021)A new bioinspired computational model was developed for the SARS-CoV-2 pandemic using the available epidemiological information, high-resolution population density data, travel patterns, and the average number of contacts ... -
Population Dynamics P system (PDP) models: a standarized protocol for describing and applying novel bio-inspires computing tools
Colomer, M. Àngels (Maria Àngels); Margalida, Antoni; Pérez Jiménez, Mario de Jesús (Public Library of Science (PLoS), 2013)Today, the volume of data and knowledge of processes necessitates more complex models that integrate all available information. This handicap has been solved thanks to the technological advances in both software and hardware. ... -
Space–time trends in Spanish bird electrocution rates from alternative information sources
Guil, Francisco; Colomer, M. Àngels (Maria Àngels); Moreno-Opo, Rubén; Margalida, Antoni (Elsevier, 2015)Interaction with man-made infrastructures is one of the main sources of non-natural bird mortality. Here, we use a long-term study (1980–2010) to analyse spatial and temporal patterns in avian electrocution in Spain, using ... -
Vaccination is a suitable tool in the control of Aujeszky's disease outbreaks in pigs using a Population Dynamics P systems model
Colomer, M. Àngels (Maria Àngels); Margalida, Antoni; Fraile Sauce, Lorenzo José (MDPI, 2020)Aujeszky's disease is one of the main pig viral diseases and results in considerable economic losses in the pork production industry. The disease can be controlled using preventive measures such as improved stock management ...
