B.L. Brown, C.M. Swan, D.A. Auerbach, Grant E.H. Campbell, N.P. Hitt, K.O. Maloney, C. Patrick
2011, Journal of the North American Benthological Society (30) 310-327
Explaining the mechanisms underlying patterns of species diversity and composition in riverine networks is challenging. Historically, community ecologists have conceived of communities as largely isolated entities and have focused on local environmental factors and interspecific interactions as the major forces determining species composition. However, stream ecologists have long embraced a...

Generalized bootstrap method for assessment of uncertainty in semivariogram inference
Ricardo A. Olea, E. Pardo-Iguzquiza
2011, Mathematical Geosciences (43) 203-228
The semivariogram and its related function, the covariance, play a central role in classical geostatistics for modeling the average continuity of spatially correlated attributes. Whereas all methods are formulated in terms of the true semivariogram, in practice what can be used are estimated semivariograms and models based on samples. A...
