The fact the Ax21 family protein are associated with competitive ability in a non-pathogen and with virulence in pathogenic bacterial species suggest that these proteins evolved to regulate key survival/ecological traits.
Also, due to the fact that athletes are divided according to body mass, the fighters are required to present a low percentage of body fat, with greater muscle development, predominantly a mesomorphic profile, which is associated with competitive success, since athletes often reduce their body mass to compete [8, 9].
Ornaments, weapons, and large body size are associated with competitive and mating success in many animal species.
However, few numbers of tested rhizobia found effective at Fedis site could be associated with the presence of competitive and high rhizobia population nodulating peanut in the experimental soil.
These reproductive gastrointestinal changes may be associated with enhanced nutrient absorption: a possible competitive advantage at a time of high nutritional demands.
Specifically, one SD increase in the use of competitive learning would be associated with an increase in mathematics performance by about 11 points in Hong Kong, about 8 points in Japan, about 24 points in Korea, and about 8 points in the USA.
Resistance or competitive ability may be associated with a behavioral defense.
If anything, co-circulation could be associated with a reduction in burden due to competitive exclusion [ 24– 26].
Good genes are those that may be associated with heritable traits related to male attractiveness, survivability, or competitive ability (Forstmeier et al. 2014).
