Nest defense in the face of cuckoldry: evolutionary rather than facultative adaptation to chronic paternity loss

Table 1 Effects of brood, parental, and territory variables on intrusion pressure by territory competitors and brood predators. Intrusion pressure was quantified as the number of defense behaviors performed by the breeding pair of V. moorii against each intruder type. Significant p-values (p < 0.05) are in bold
