Ecological filters related to climate, competition, herbivory, and soils all differentially affected aspen presence, persistence, and size.
To evaluate the effect of clomiphene citrates (CC) on inducing ovulation and on cyst persistence and size in women with functional ovarian cysts.
We modeled the influence of different rates of harvest and proportions of landscape dedicated to un-hunted reserves on population persistence, population size, social dynamics, and hunting yields of red howler monkeys.
In this paper, we compared the effect of road mortality and of the barrier effect on population isolation, persistence and size, and assessed the interaction of these effects with dispersal.
Age-related antibody profiles were heterogeneous between farms, and much of the heterogeneity is explained by covariates that would be expected to be related to virus introduction (pig density, quarantine) or persistence (herd size).
Taking the upstream area of the Minjiang River, China, as a case study, the result indicated that the major forest cover classes had a high rate of persistence in area size during the study period, while conversions among forest covers and into non-forest land occurred frequently, accounting for 5.4% of the landscape.
There may or may not be a preferred spatial direction, correlations in step size, persistence in direction of motion, oscillations in the velocity, etc.
Those models indicated that CDV would have little effect on wolf population persistence or pack size (23, 24 ).
Our observations, based on replicated, standardized cultures, show that cercomonad strains with identical 18S rDNA but different ITS1 sequences can differ in several respects: salinity tolerance, propensity to form cysts, vigour in standard non-saline media (growth density and persistence over time), size and basic cell morphology (Table 2).
Several methods for determining persistence length from size-exclusion chromatography data are evaluated for a stiff polymer, poly n-hexyl isocyanate) (poly n-hexylhe more flexisocyanate2,7-(9,9 di-n-hexylfluorene)].
