Passive choice and possible mate guarding in the stonefly Pteronarcella badia (Plecoptera: Pteronarcyidae)

Evidence for passive choice for near males in Pteronarcella badia was demonstrated by comparing female answering rates to near males (30 cm distance) versus distant males (60 cm distance). Though statistically different, female answering rates were high to both near and distant males suggesting that...

Zusammenfassung:Evidence for passive choice for near males in Pteronarcella badia was demonstrated by comparing female answering rates to near males (30 cm distance) versus distant males (60 cm distance). Though statistically different, female answering rates were high to both near and distant males suggesting that males may engage in a form of scramble competition to locate the female before another competing male(s). Evidence for mate guarding in P. badia is presented and discussed. The possibility of purposeful interference signaling between near and distant males was considered, but the data gave no indication of this behavior. /// La evidencia para la selección pasiva de machos cercanos de Pteronarcella badia se demostró comparando las respuestas de las hembras a los machos cercanos (30 cm. de distancia) y contra los machos distantes (60 cm de distancia). Aunque estadisticamente diferente, las respuestas de las hembras hacia los machos fueron altas a ambos, cercanos y distantes, sugiriendo que los machos podrian entregarse a una forma de competencia confusa para localizar las hembra antes que otro contendiente. La evidencia para un guardián del macho o hembra en P. badia es tambien presentada y discutida. Se consideró la posibilidad de un sistema de señales de interferencia intencional entre los machos cercanos y distantes pero la evidencia no proveyó indicaciones claras de esta conducta.
