Live aboveground biomass (AGB) is an important source of uncertainty in the carbon balance from the tropical regions in part due scarcity of reliable estimates of live AGB and its variation across landscapes and forest types.
This decision is also supported by the scarcity of available estimates using hedonic pricing (Carlucci et al. 2014).
One of the greatest limitations in interpersonal violence research among AI/AN is the scarcity of valid prevalence estimates.
In general, the relationship between population size and mtDNA diversity is difficult to evaluate because of the scarcity of population size estimates for wild species.
8 10 The scarcity of HIV incidence estimates may be due to the logistical and financial difficulties in following high-risk populations for long periods of time, indeed a formidable task for vulnerable populations most affected by HIV.
Given the scarcity of studies simultaneously estimating reproductive assurance, selfing rate and lifetime ID along natural population size gradients, predicting the potential of selfing to provide actual reproductive assurance in various ecological contexts remains a major challenge in evolutionary biology.
Because of the relative scarcity of silver, Mr. Köhler estimates that demand for an e-textile product on the mass market could eventually require 12 percent of the global silver supply.
As such, added with the scarcity of local data, which estimates the proportion of patients who receive post stroke treatment from which type of health facility after the acute period makes it difficult to account on how efficient post stroke care is delivered.
DeepWater Desal's desalination highlights another major global problem: a scarcity of water that threatens an estimated 4 billion people.
The scarcity of data providing a direct estimate of the human absorption of Pb particles is a significant limitation on our ability to estimate bioavailability, a shortcoming that is partially addressed by the use of the most representative animal model.
Scarcity of challenge trials prevented us from estimating age-related infection rates (LPAI and HPAI) and latent period (LPAI); therefore, we used mean estimates from both age classes (Table 1) in model projections and sensitivity analyses.
