Between-species patterns of covariation in plant size, seed size and fecundity in monocarpic herbs (2001, background): “Fitness is zero unless reproduction occurs quickly before the next disturbance event and it is relatively inconsequential to fitness that successful species in the face of such selection pressure are also relatively small (Harper, 1977; Taylor, Aarssen & Loehle, 1990; Aarssen, 2000).”
Death without sex—the ‘problem of the small’ and selection for reproductive economy in flowering plants (2008, background): “herbaceous and woody perennials) (Barrett et al. 1997); the vast majority of predominant selfers are, in fact, relatively small annuals ( Aarssen 2000 ).”

Weed-insect pollinator networks as bio-indicators of ecological sustainability in agriculture. A review (2016, background): “In agreement with the time limitation hypothesis, self-pollination is crucial for rapid seed formation (Aarssen 2000).”
Response and effect traits of arable weeds in agro‐ecosystems: a review of current knowledge (2017, background): “A strong association between self-pollination (in particular predominant and autonomous selfing) and the annual life form have been documented, suggesting that most annual species are self-compatible (Aarssen, 2000).”
Patterns of plant traits in annual vegetation of man-made habitats in central Europe (2006, background): “This is probably due to the fact that selfers are generally overrepresented among annual plants (Aarssen, 2000), and annuals are more frequent on arable land than in settlements.”
