Research Interests
My research is aimed to improve our understanding of processes that generate, maintain and affect biodiversity and upon that knowledge design and evaluate strategies for the protection of biodiversity (see diagram below). The rational is that achieving effective protection of biodiversity requires basic knowledge on 1) how human activities affect biodiversity and 2) how biodiversity is regulated and maintained over time. The former piece of knowledge provides the arguments to control certain threats whereas the later helps to prioritize limited conservation resources on key locations. In addition, my research also focuses on the assessment of strategies that are already in place for the conservation of biodiversity. It is always my interest to address those issues at the widest spatial scales possible. 

Causality of threats.
Many marine and terrestrial species are in the slippery slope to extinction due to human related threats such as overexploitation, habitat loss and climate change. Unfortunately, there is significant uncertainty on the actual causality of these threats, which in turn has generated strong controversies but more importantly has precluded the development of earnest mitigation policies. This part of my research uses experimental approaches to evaluate the effects and mechanisms by which human-related threats lead to population declines and threat species with extinction.

Causes of biodiversity.
Describing and explaining spatial patterns in species richness are longstanding goals in ecology. Interest in these goals has gained momentum due to escalating anthropogenic impacts, and the need to prioritize limited conservation resources on key areas and hotspots of extinction-prone species. This part of my research uses meta-analysis approaches to describe patterns and test the causality of potential hypotheses. I use a wide variety of spatial statistics, Geographical Information Systems and Visual Basic programming to construct accurate patterns and develop rigorous tests of mechanistic hypotheses.

Development of conservation strategies and assessment of their effectiveness. Conservations strategies should be preceded by rigorous basic science if such strategies are expected to be effective.  Unfortunately, such basic science is being developed at the same time that biodiversity is being loss. This has prompted the creation of regulations with rational but poor scientific sustentation. As a result, the success of such regulations is an open question. This part of my research aims to evaluate the effectiveness of strategies that are in place for the protection of biodiversity. I use meta-analysis approaches and scientific surveys to evaluate the effectiveness of existing strategies in terms of compliance, enforcement and biological response.

SIO209: Course Description
Simple methods for analyzing large data sets and answering global scale questions

Winter 2008

The Internet, through different venues, has made possible collecting and/or accessing huge amounts of data over large geographical scales. These data, which in most cases can be downloaded with the click of a mouse, have allowed in-depth analysis of the mechanisms through which humans are causing the decline of the world's biodiversity and assess  patterns and mechanisms over scales never possible before. Although these amazing sources of data are extending the frontiers of ecology they demand new analytical skills from ecologists. At a first glance these skills may appear to be restricted to computer geeks given that they require understanding of different programs associated with database management, data queries, geographical information system, programming and statistics. When faced with the challenge, however, you will realize that most of these tools are actually very SIMPLE. This course is intended to describe such tools. The course will be divided in two parts. The first one will describe tools from programs like Microsoft Access, Excel, Visual Basic, Statistica and ARCgis, which will provide the necessary skills to analyze large databases. In the second section, we will tackle one or two research questions (depending on the number of students) in which we will apply the learned tools or new ones if required. This second section will include reading and discussion of relevant literature (to outline the scope of the problem and data needs), search and analysis of the relevant data and writing of a report. I will encourage tackling a novel question so that the report of this second section has the potential to be of quality worth publishing in a peer-review journal.
