In Silico Science: Ecology Without the Nature

When dealing with complicated ecological concepts, theoretical models – though they may seem abstract – often help create bridges to fill in our understanding, writes Thomas Haaland (Image Credit: Aga Khan, CC BY-SA 4.0, Image Cropped)

It should not come as a surprise any more that most ecologists don’t spend all that much (work) time outside. Numerous posts on this blog about data management and ecological modelling draw a picture of a modern biologist spending most of their time in front of a computer rather than out in the field. However, the work is still intimately related to the natural world. Gathering the data is simply the first step on the way to scientific understanding, and between organizing data, analyzing data, interpreting results and writing them up, the computer hours just vastly outweigh the outdoor hours. But there is another, more mysterious breed of researchers that has even less to do with nature: theoretical biologists.

Behavioral Ecology for the Masses

Previously on this site I’ve summarised an article I wrote linking some concepts from behavioral ecology with evolutionary biology. Now I’m back to say a bit more about what behavioral ecology actually is. Being introduced to the field of behavioral ecology was what sparked me to actually consider a career in science. It’s a fascinating and beautiful field, and I hope I can show you why!

Are Animals Doing the Wrong Thing?

The Crux

Why do animals behave the way they do? Behavioral ecology is a field of research trying to explain the ecological rationale of animal decision making. But quite often, it turns out the animals are doing the ‘wrong’ thing. Why don’t all animals make the same choice, when there clearly is a best option? Why do animals consistently do too little or too much of something?
