Annual plant neighbourhoods

As a team, we are discussing the fine-scale grain of sampling for estimating annual-annual plant interactions in deserts. We are particularly interested in the Mojave Desert to examine pollinator-herbivore interactions with annuals that are mediated by the other immediately adjacent congeneric species. Here is a brief compilation of key papers examining this challenge.

scale matters, a plant’s eye view

Personal vote

I am a fan of the 15cm scale for fine-scale but often sample with a 15cm ring nested within a second 30cm metal ring. I construct using wire.
