Paulo Inácio Prado

I am a biologist, PhD in Ecology and teacher at the Ecology Department from the Instituto de Biociências of Universidade de São Paulo.

Before that I was an associate researcher at Environmental Research Center of Unicamp and associate teacher at Pontifícia Universidade Católica de São Paulo.

My intellectual project is to give more theoretical rigor to Community Ecology. My strategy is to deduce ecological patterns from first principles, and then subjecting them to rigorous empirical and logical tests.

It is also my goal to train researchers who combine deep critical thinking with a solid background in ecology and in the logic of the scientific method.


Research

Imperfect detection - Does it matter?

Goal

To evaluate the sensitivity of the results and conclusions of selected case studies to the inclusion of imperfect detection.

Background

The advancement and application of ecological theory depends on unbiased and precise estimates of occurrence, size and vital rates of populations in ecological systems. There is a growing concern that such estimates are strongly affected by observation bias; the most obvious case are false absences. A formalism of hierarchical statistical models to tackle the problem is now available. Colletively known as hierarchical models with imperfect detection, such statistical methods could be applied much more widely than they currently are. Nevertheless, this new approach involves complex statistical procedures and larger sampling efforts. Thus, it is necessary to evaluate the effective gains of the models with imperfect detection in different types of ecological research.

Species Abundance Distributions

Because I seek first principles, one of my research interests is perhaps the only general law in Community Ecology: the predominance of rare species.

My main research project is to develop an analytical protocol to describe this pattern. The research was funded by FAPESP and CNPq, and you can find more information here.

Many of my students also do their research on this topic, see the page of research projects.

Patterns of Biological Diversity

One of the basic approaches of community ecology is to identify patterns and regularities to infer their underlying structuring processes. I was trained in this tradition of observational research, and I specialized in statistical analysis to detect ecological patterns. I keep researching and advising on this subject, see the page of ongoing projects.

More recently, I also started some experimental approaches, like manipulative research in the field, and “virtual experiments” with computer simulations.

Structure in Biological Interactions

I still take part in the research group I graduated, led by Dr. Thomas Lewinsohn, at Unicamp.

I work in collaboration with them and other colleagues in the search for patterns in ecological networks, with emphasis on antagonistic systems of herbivorous insects and their host plants.

Applied Ecology

On many occasions I could use my skills in analysis and ecological theory to applied research, especially in conservation biology.

Currently these issues are not my main line of investigation, although I keep some ongoing collaborations.

Teaching

In collaboration with many colleagues, I created and teach the courses at the Graduate Studies Program in Ecology at USP

Also at USP, I'm one of the teachers who coordinate our Field Course for graduate students, and the undergraduate course of Population and community ecology of plants.

A comprehensive list courses I teach is in the page of teaching acitivities.
