Modelling the abundance of Culex pipiens in Portugal

Sala: 6.4.30, FCUL, Lisboa

Por Patrícia de Zea Bermudez Marília Antunes (Centro de Estatística e Aplicações da Universidade de Lisboa)

Arthropod are the transmission vectors for the arbovirus, of which the Culex pipiens is the most common species. In order to assess which species are most commonly observed in Portugal and their distribution throughout the country, the National Health Institute, along with the regional and national health authorities, developed a vectors surveillance program. Mosquitoes are captured using traps, and ecological, meteorological and geographical coordinates are recorded at the location of the capture. The geographical coordinates allow to obtain georeferenced information on variables that may affect the presence and abundance of the mosquitoes, such as the proximity of water masses.

The data concerns the number of mosquitos captured per trap and were recorded between May and October, 2006-2012. The observations are neither spatially nor temporally regularly distributed and, consequently, the data does not cover the whole country. One of the most relevant features of the data is the large amount of zero counts and also and presence of over-dispersion. Zero inflated Poisson (ZIP) and Zero inflated negative binomial (ZINB) models were fitted to the counts and compared to the traditional Poisson and Negative Binomial models. The models were fitted to the expected number of specimens captured, considering several geographical and meteorological as explanatory variables, both in frequentist and bayesian frameworks. A spatial modelling of the data in a Bayesian point of view will also be briefly addressed.

The objective of this course is to acquire knowledge regarding bioinformatic tools available to predict nucleic acid (RNA, DNA or Nucleic Acids Mimics) and protein three-dimensional structure, as well as autonomy and critical thinking in the use of those tools.

Science is increasingly more present in our everyday decisions, with a fundamental role in global problems. Scientists, as the main actors in the production of scientific knowledge, have the responsibility of having an active voice in communicating this knowledge.

The course aims at introducing attendants to an updated state of the art of diversity of the soil biota and the functional roles played by soil organisms in key ecological processes.

Symbiosis is a key strategy for life on Earth. Nevertheless, although many research groups have long been committed to the study of symbiosis, its definition and functioning are not fully understood, and its ecological role and relevance are still underestimated.

This 5-day course offers to the participants a light microscopy course focusing on fluorescence microscopy techniques applied to the detection of proteins and glycans in tissue samples and cell cultures.

This course aims to explore ways of communicating science to non-specialized audiences, such as policy makers, industry, general public (including students and teachers), through their engagement and participation in citizen science activities.

The objective of this course is to provide students with basic knowledge of R programming, allowing them to manipulate and visualize data with R.

The objective of this course is to provide students with statistical knowledge and tools to manipulate, analyze and visualize biological data with R. Introduction to modeling, simulations and Bayesian statistics.

Under the general framework of Global Change Ecology, the goal of this course is to provide the participants with the most recent and practical knowledge on the use of Functional Diversity. This includes the selection of functional traits and calculation of Functional Diversity Indexes.
