Here, we show empirically that predatory birds can act as agents of frequency-dependent selection on terrestrial salamanders.
Here, we show that predatory birds can act as agents of frequency-dependent selection on terrestrial salamanders.
Here, we test whether predatory birds can act as agents of frequency-dependent selection on terrestrial salamanders using a manipulative field experiment.
In this way, intraspecific competition acts as an agent of frequency dependent disruptive selection, which favors two or more modal resource-use phenotypes in the same population [ 35, 38, 39].
Adequacy of empiric antibiotic therapy was reached in 69% of the cases, similar in both groups, without any difference in the type of agents used, frequency of combination therapy (75 and 80% in B+ and B- groups) or duration of therapy (11 (6) days).
Recent evidence indicates that the choice of sedating agents, frequency of administration and regular assessment of sedation contribute to patient outcomes [ 7- 9].
We considered interacting with it to be akin to being set into the shoes of a child drummer who likes to play a drum periodically by him or herself, but who is also very capable of cooperating with external agents to synchronize frequency of oscillation and amplitude.
There are three competing factors affecting the brightening reaction arising from pulp consistency: effective chemical concentration in the brightening liquor, accessibility of chromophores to the active chemical agents, and frequency of the chromophore chromophore contact.
A similar SAR dependence of the particle concentration is observed, although differences in the absolute values could derived from the slightly different particle size, particle distribution, coating agent or experimental conditions of frequency and applied magnetic field.
Although some patients received corticosteroids and immunosuppressive agents, the frequency of usage was not different between the groups.
Distinct microorganisms are described as agents of VAP, and their frequency may differ according to many factors, including the population of patients in the ICU, duration of hospital stay, and methods of diagnosis.
