Does intraspecific competition among Allenby's gerbils lead to an Ideal Free Distribution across foraging patches?

abstract：:According to sexual selection theory, age affects the preference of mate choice, and this preference ultimately influences the fecundity of the female. Pardosa pseudoannulata (Araneae: Lycosidae) is a valued predator in many cropping systems. By determining oviposition rate, egg hatching rate, and also the number and ...
