Researcher for biogeography and predictive modelling at the Centre of Geographical Studies, University of Lisbon (CEG-IGOT).
Hi, my name is César Capinha and I am an environmental scientist with focus on biogeography, biological invasions and machine learning. I'm currently Ass. Professor at the Univ. of Lisbon and Researcher at the Centre for Geographic Studies (Univ. of Lisbon).
My main research interests revolve around the analysis and prediction of biogeographical changes caused by human mediated dispersal of species, with a global scale perspective. I increasingly tackle these topics via state-of-the-art machine learning approaches and small-to-big data sources.
Keywords: Biogeographical Change | Biological Invasions | Macroecology | Predictive Modelling | Machine Learning and Artificial Intelligence
You can find me with my group of great researchers and students at Biochange.pt;
Also as Associated Editor @ Diversity and Distributions, on ResearchGate and at Google Scholar;
At my institution: CEG-IGOT, UL, and as full member of the Sigma Xi Scientific Research Honor Society.
You can reach me directly at: cesarcapinha(_at_)campus.ul.pt

New POSTs:
We have recently made available a preprint on the use of deep learning for classifying time series. This is an exciting avenue of future work in ecology, with many possibilities of application. Still a preprint, but a quite cool one in our opinion :)

-> OLDER POSTS:
In a paper published in NeoBiota we show that regional numbers of alien species are hard to predict.
Numbers of alien species remain unknown for many regions of the world. Plausibly, models fitting the relationships between known numbers and the environmental and socioeconomic attributes of the corresponding regions could help cover the knowledge gaps. We tested this possibility and found that the predictive accuracy of this approach is generally low, particularly when predictions are made for regions outside the geographical boundaries of the available data (e.g. if data from the US is used to predict in Australia). In sum, we show that predicting numbers of alien species is very challenging, ultimately emphasizing the need to reinforce the surveying, publication and updating of distribution data for alien species. Read the full paper here.
-> Last September I gave a long interview to a national radio station (Antena 1) regarding alien species and their impact on global biogeography. You can listen to the full interview here (in Portuguese): http://www.rtp.pt/play/p2063/e250799/ponto-de-partida
-> Happy to announce that we just got out a paper on the global biogeography of alien herptiles in the journal Diversity and Distributions. See paper here.
-> "Assessing future habitat availability for coastal lowland anurans in the Brazilian Atlantic rainforest"
One sentence summary: Sea level rise may drastically reduce available habitat for some species of coastal anurans in the Brazilian Atlantic rainforest. You can find the paper here.
-> Editor's introduction to our new paper in the journal Science analyzing the global-scale biogeographic pattern that is emerging among terrestrial gastropods being dispersed by human activities:
"Human influences are leading to a shift in the geographical distribution of animal species. Capinha et al. compared the distributions of native mollusk species with those introduced to new areas by human activities. The ranges of native species are still broadly constrained by limitations on their capacity for dispersal, whereas those of the introduced aliens are affected more by climate and patterns of human movement. As humans continue to break down barriers to dispersal, more species’ distributions will come to be limited by their environmental tolerances." You can find the paper here.
-> I am no longer maintaining my (old) capinha(at)uevora.pt e-mail. If you want to contact me please use the email address provided above.
-> I recently moved to the CIBIO/InBIO Research Centre. (07-05-2015)
-> Editor's introduction to our new paper on the global distribution of Aedes aegypti, the main vector of dengue: "Capinha et al. focus on the importance of macroclimate in shaping the distribution of Aedes aegypti - a domestic mosquito that is the main vector of dengue, a highly prevalent disease. Using a correlative model, they show that much of the species range outside tropical regions is sustained by man-made environments but that the boundaries of this range are set by macroclimate barriers. This suggests that global climate change may have profound effects on the future distribution of this important disease-vector." Read it here.
Predicting species distributions with alpha-shapes
->I and Beatriz Pateiro-Lopez have a new paper in Ecological informatics concerning the use of alpha-shapes for predicting the potential distribution of species in new areas (as for invasions) or time periods (as under future climates). Alpha-shapes are an extremely simple and intuitive geometric delimitation method which only requires occurrence data and that does not assume the shape of the niche a priori − as BIOCLIM or Mahalanobis distances do. Here I show how this method can be implemented in R for delimiting a specie's realized niche.
-> On the 5th of February I'll give a talk about how observed patterns in the climatic conditions occupied by invaders may help assessing the a priori uncertainty of climate-matching predictions. The talk will start at 12:00h and will take place in the Faculty of Sciences of the University of Lisbon. Read more about it here.
->A visit to the German Centre for Integrative Biodiversity Research - iDiv is on my schedule for next week. It will also be a great opportunity to get to know Lepzig. (29-11-2013)
->A talk of Walter Jetz at CBA. For this and other great guests have a look here :) (07-09-2013)
->During July and August I'll be at the Alexander Koenig Research Museum in Bonn. A very nice place (and location: about 100m from the Rhine) with really great people (and beer and pizza...) but, so far, awful weather... I'm working with Dennis Rödder on some analyses of the distribution of non-native terrestrial gastropods. This work also counts with the contribution of Heike Kappes from Naturalis and Herique Pereira, my PI. Hopefully it will see the light of day in a few months. (22-07-2013)
