On why we need more life history oddities to examine life history evolution
Most of the tenets of life history that are currently widely used in ecology and evolution were in fact developed quite a few decades ago, when only data for mammals and birds were available. Those tenets (e.g. senescence is universal, trade-offs are everywhere, etc.) have since been assumed universal… but are they really? With the recent development of open-access repositories of demographic data for thousands of species, we are now in an unprecedented position to test such classical tenets and to examine their validity across the tree of life. I will draw on comparative analyses on hundreds of animal and plant species to argue that we should pay more attention to life history oddities -rather than comparatively overstudied charismatic fauna & flora- in order to quantify biodiversity and understand potential effects of climate change on it. Take-home message: it’s time to re-write a lot of our ecology 101 textbooks.
