Re: Please read! About life history strategies!

I agree with basic biology here. R selection will result in the best overall fitness for such a species. There are a number of clues in the question that help elucidate the ecology of this given species we shall call A. Now A, being an annual ...

The evolution of facilitation and semelparity

Another quick topic here I'm a bit confused about. Why would a species have evolved to the extreme of r-selection(=semelparity)? i.e. only one reproductive episode before death, like the Mayfly. Same thing with facilitation, with one species doing all the work, despite no direct ...
