As such, we focus here on the uncertainties concerning the current level of fulfillment of emission reduction targets that relate to historical base year or reference values (e.g., Australia, China, Gabon), unclear scenario projections (e.g., Brazil, Mexico, the Russian Federation), as well as unclear sectorial composition of overall emission reduction targets (e.g. USA).
Considering our data and the published work, it is still unclear which scenario might be true.
Firstly, a rapid ecological speciation event with an unclear sympatric scenario, i.e. the derived species C. fontanae fully differentiated from C. albula physiologically, ecologically and morphologically within about 12 – 14 kyrs in the newly colonized Stechlin Lake after the last glacier retreated [ 15].
From the unclear evolutionary scenario at deeper ray-finned fish levels it also follows that at these deep levels in some instances our working definitions of U, Z, P, S and L, which are based on phylogenetic tree analysis, may not correctly represent genuinely separate lineages.
Who benefits in this scenario is unclear.
Despite this long tradition of prescriptive research, PM methods suffer from a number of problems, such as a lack of acceptance in practice, limited effectiveness, and unclear application scenarios.
For reasons that are unclear, in scenarios involving small versus large Nb (Nb = 24 vs. 50 or 100), small Nb populations also lost rarer alleles more readily than that predicted by the discrete generation model in the early generations, but this effect disappeared after about 10 generations (details in Waples 1990).
But even under this scenario, it's unclear how such a low-mass planet could form, researchers said.
Having developed scenarios within foresight management, it is often unclear for what scenario a company has to be prepared.
Consider this hypothetical scenario.
Imagine this new scenario.
