Geographically, the 17-year brood populations fit together like puzzle pieces.
The structure of the brood mare population for age and reproductive history has not been studied in other breeds with the exception of the TB.
In addition, the five species for which paternity data are available show remarkable variation in EPP rate, with between 5.8% and 95% of broods in a population containing one or more extra-pair offspring, and EPP accounting for as little as 4.4% or as much as 76% of all young in a population [46] [52].
and matched for areas of honeycomb containing brood and food, and population size.
The model that we present here is very simple and focuses on the effect of varying forager death rate on brood and adult bee population dynamics.
Using germinal transgenesis has the advantages of several hundred tadpoles per brood and a homogeneous population in terms of transgene insertion site and consequent regulatory controls.
In general, timing variation between broods from a given population is expected to be much greater than within a single brood, even at early stages.
Among the endangered cicada populations is Brood VII, in upstate New York, now largely restricted to the Onondaga Nation south of Syracuse.
Each brood consists of scattered populations across the country, which all appear simultaneously on either a 13- or a 17-year cycle.
We determined the proportion of simulations out of 1000 that correctly assigned the true number of fathers (from 2 5), given various sample sizes of larvae genotyped (range, two – 96; actual mean sample size across the 14 broods =29.74) and the population allele frequencies of the four most commonly used markers (Pole 1, Pole 8, Pole 25, and Pole 44) from Baja California, Mexico [ 72].
In this generation of our stock population, for example, brood size at dispersal in stock broods ranged from 3 to 24.
