The web of life is composed of two distinct threads – one that links organisms at any given moment in time through the flow of energy (ecology), and another that connects all biota through deep time via genetic information and shared common ancestry (evolution). Ecology and evolution, in a single theme, provide a robust scientific platform for understanding biodiversity and appreciating the big story of life. Why are there so many species? What are the factors influencing species distribution and abundance? Where do we belong in this bewildering design?
I ponder and am interested to answer some of the big questions in ecology and evolution, while teaching ecology from an evolutionary perspective.
If we wish to examine the effect of predation on snails, seeds and beetles, we would soon discover that individuals exposed to heavy predation have harder exteriors than those not exposed to predation. Why are the exteriors hard and thick for some and soft and thin for others? The first answer is the presence and absence of predation coupled with a long course of natural selection. The question cannot be answered by examining the materials that make up the exteriors. The point is that while studying organisms, populations and communities and the patterns they reveal, we also need to understand the processes that produce them.
I address, in my teaching and research, both patterns and processes. I use the techniques of mud-and-boots field biology vis-à-vis the theory of foraging to understand the patterns and processes responsible to structure and shape populations and communities.
