In a habitat there are 7,500 individuals of P. rufipes, 40% of which have long and thin ovipositors and 60% have short and thick ovipositors. During a single year 250 wasps with long and thin ovipositors died while 325 were born. In that same year, 650 wasps with short, thick ovipositors were born and 800 died. Calculate the per capita growth rate (r) of the two subpopulations of P. rufipes. Per capita growth rate of P. rufipes with long and thin ovipositors: _________ Per capita growth rate of P. rufipes with short and thin ovipositors: _________
