The thermophilic fungus Scytalidium thermophilum (also known as Humicola insolens; Straatsma and Samson 1993) removes ammonia during PII and suppresses competitors of A. bisporus (Ross and Harris 1983; Straatsma et al. 1989, 1994).
This is followed by a 3-day-period at 45 °C during which thermophilic fungi like Scytalidium thermophilum (also named Humicola insolens; Straatsma and Samson 1993) colonize the compost sequestering ammonia and suppressing competitors of A. bisporus (Ross and Harris 1983; Straatsma et al. 1989, 1994).
Group 4 species have larger fruiting bodies because their cAMP oscillators are better at suppressing competitors.
Conditions in wetlands may not enhance CO2 assimilation rates of C4 plants to the degree needed to suppress C3 competitors; alternatively, wetland C3 plants may be well adapted for marshy environments for reasons unrelated to photosynthetic pathway.
Alternatively, they could suppress microbial competitors for infection of the host tissues or digestive system, defend the host against pathogens, or play a role in communication with the host.
Microbes may do this through two potential strategies: (i) generating cravings for foods that they specialize on or foods that suppress their competitors, or (ii) inducing dysphoria until we eat foods that enhance their fitness.
The biased-competition framework assumes that when two (or more) neural assemblies compete with each other for representation, attentional biases in the system operate (over time) to make one assembly win the competition and suppress the competitor(s).
But tests in isolation demonstrate that it's Yik Yak itself suppressing its competitors.
However, a perennial plant may receive direct, albeit delayed, fitness benefits from suppressing potential competitors, in which case solar tracking would not be an example of spite.
