Effects of hydrological variability on fish assemblages in small Mediterranean ...
Matono, Paula; Bernardo, João Manuel; Oberdorff, Thierry; Ilhéu, MariaSmall Mediterranean streams are shaped by predictable seasonal events of flooding and drying over an annual cycle, and present a strong inter and intra-annual variation in flow regime. Native fish assemblages in these streams are adapted to this natural environmental variability. The distinction of human-induced disturbances from the natural ones is thus a crucial step before assessing the ecological status of ...
Coefficient shifts in geographical ecology: an empirical evaluation of spatial ...
Bini, L. Mauricio; Diniz-Filho, J. Alexandre F.; Rangel, Thiago F. L. V. B.; Akre, Thomas S. B.; Albaladejo, Rafael G.; Albuquerque, Fabio S.Copyright © 2009 The Authors. Copyright © ECOGRAPHY 2009. ; A major focus of geographical ecology and macro ecology is to understand the causes of spatially structured ecological patterns. However, achieving this understanding can be complicated when using multiple regressions, because the relative importance of explanatory variables, as measured by regression coefficients, can shift depending on whether spati...
