From: “Shell resource partitioning as a mechanism of coexistence in two co-occurring terrestrial hermit crab species”, S. Steibl & C. Laforsch (2020), BMC Ecology 20:1 https://doi.org/10.1186/s12898-019-0268-2 A fairly fundamental concept in ecology and evolutionary ecology is the competitive exclusion principle – that complete competitors cannot coexist. That is, a situation in which two species which …

Blumstein (2019), Current Zoology zoz046 https://doi.org/10.1093/cz/zoz046 The vast majority of wild animals will, if a person walks towards them, run or fly away. For something so commonsense and easily taken for granted, this is actually quite poorly understood as a phenomenon. …
