Driving forces behind female-female aggression and its fitness consequence in an Asian agamid lizard

Female-female
aggression and its effect on fitness are poorly understood compared to
male-male aggression. We
quantified female-female aggression in the toad-headed agamid lizard, Phrynocephalus vlangalii, and tested two
hypotheses, mate limitation hypothesis (females are aggressive when male
availability is low) and resource competition hypothesis (females are
aggressive when resource availability is low), to explain the driving forces of
heightened female-female aggression and its fitness consequence. We
established populations in large outdoor enclosures in the field and separately
manipulated mate and food availability while quantifying aggressive interactions
between known females. Female mass, and offspring quantity and quality, were
monitored for two years and used as measurement of female fitness. The dataset aggression_mate_2012.csv is about the mate limitation experiment, the dataset aggression_food_2013.csv is about the resource competition experiment, the dataset female_birth.csv is about female birth probablilty in 2013 and 2014 during recource competition experiment, the dataset female_quality.csv is about female quality in 2013 and 2014 during recource competition experiment, the dataset offspring_growth_survival.csv is about offspring growth and survival in 2013 and 2014 during recource competition experiment, the dataset offspring_quality.csv is about offspring quality in 2013 and 2014 during resource cmpetition experiment.
