Figure 6. Outlinks degree distribution for all web sites-Study of a Random Navigation on the Web Using Software Simulation
<p>Some of the most important aspects of the analysis is obtaining the parameters which can<br> give the main information about a web. In the simulation implementation information as: page,<br> number of inlinks, number of outlinks, value for Algorithmic Page Rank and Experimental Page<br> Rank will be processed for obtaining the results of the analysis. For the first part it was necessary to<br> use experimental values as: inlinks, outlinks and in and out frequencies.</p>
The role of growing degree-days in explaining moth species distributions at broad scales
<p>Growing degree-days (GDD), an estimate of an organism's growing season length, has been shown to be an important predictor of Lepidopteran species' distributions and could be influencing Lepidopteran range shifts to climate change. Yet, one understudied simplification in this literature is that the same thermal threshold is used in the calculations of GDD for all species instead of a species-specific threshold. By characterizing the phenological process influenced by climate, a species-specific estimate of GDD should improve the accuracy of species distribution models (SDMs). To test this hypothesis, we use published lab-estimated thermal thresholds and modeled the current geographic distribution of 30 moth species native to North America. We found that the predictive performance of models based on a species-specific estimate of GDD was indistinguishable from models based on a standard estimate of GDD. This is likely because GDD was not an important predictor of these species' distributions. Our findings suggest that lab-estimated thermal thresholds may not always scale up to be predictive at broad scales and that more work is needed to leverage the data from lab experiments into SDMs to accurately predict species' range shifts in response to climate change.</p>

Global Gridded Soil Phosphorus Distribution Maps at 0.5-degree Resolution
This data set provides estimates of different forms of naturally occurring soil phosphorus (P) including labile inorganic P, organic P, occluded P, secondary mineral P, apatite P, and total P on a global scale at 0.5-degree resolution. The data were assembled from chronosequence information and global spatial databases to develop a map of total soil P and the distribution among mineral bound, labile, organic, occluded, and secondary P forms in soils. Uncertainty was calculated for the different forms. The data set has no explicit temporal component -- data were nominally for the pre-industrial period ca. 1850.The estimated global spatial variation and distribution of different soil P forms presented in this study will be useful for global biogeochemistry models that include P as a limiting element in biological production by providing initial estimates of the available soil P for plant uptake and microbial utilization (Yang et al., 2013).There is one netCDF data file (.nc) with this data set.
TRMM Radar Rain Distributions L3 1 month 5 degree x 5 degree V7 (TRMM_3A26) at GES DISC
The new version of these data is in GPM-like format (consistent with the GPM Dual-frequency Radar data format), and can be found under the name GPM_3PR. This dataset contains distributions of monthly surface rainfall. These data were derived from rain rate statistics and include the estimated values of the probability distribution function of the space-time rain rates at four levels (2 km, 4 km, 6 km, and path-averaged) and the mean, standard deviation, and probability of rain derived from these distributions. Three different rain rate estimates are used as input to the algorithm: (1) the standard Z-R (or 0th-order estimate having no attenuation correction); (2) the Hitschfield-Bordan (H-B); and (3) the rain rates taken from 2A25.
