The lower CI values indicate that oysters in all of the low-salinity treatments were stressed compared with original field collections, even though the mortality of the experimental population
was not observed at the end of the trial.
Input data specifying the proportion of male recruits and the transitions between the 4 different stages (i.e., female-transitional-secondary-dominant) differed among the 3 experimental populations
. For the G case, half of the recruits were males ([[rho].sub.1]=0.5; Fig.
Moreover, the ESA and FWS regulations establishing this division include various provisions that treat experimental populations
as less valuable.
Rainey, "Adaptive divergence in experimental populations
of Pseudomonas fluorescens.
In contrast, experimental populations
that only experienced transit extinction tended to preserve their alleles.
We then used these size classes to assemble three different kinds of experimental populations
by systematically increasing the variation in initial body size, while keeping mean initial size approximately the same.
Dynamics of experimental populations
of native and introduced blowflies (Diptera: Calliphoridae): mathematical modelling and the transition from asymptotic equilibrium to bounded oscillations.
All 15 replicates of each treatment received the same amount of irrigation and liquid fungicide, as well as the same intensity of incoming sunlight (experimental populations
The germplasm sources consisted of 20 cultivars or experimental populations
and 21 collections from native prairie remnants in Indiana, Michigan, Minnesota, Ohio, and Wisconsin.
Population size and density were manipulated in experimental populations
to independently test the effects of these two factors.
The first is that, in education, lacking the white rat and the fruit fly as experimental populations
, random assignment is often impossible, and since humans -- beings both sentient and volitional -- are involved, random assignment might itself influence outcomes.
Editorial for ESA includes coverage of: listing and critical habitat designation; conservation and recovery plans; prohibited acts and penalties; consultation; incidental take permits; the exemption process; state and federal interactions under ESA; experimental populations
; and, suits, standing and procedure.
