  abstract = {{I}n the {A}mazon floodplains, hydrological variability plays a crucial role by shaping the habitat, offering shelter and feeding or breeding areas. {D}uring the dry season, some fresh water turtles such as the yellow-spotted turtle ({P}odocnemis unifilis {T}roschel, 1848) use the sand banks at point bar areas as breeding sites, which must be available in time for the start of oviposition. {I}n this study, we used altimetry-derived water level data from radar satellites combined with in-situ hydrological measurements to evaluate water level variations and relate them to oviposition starting dates (2003-2012) from {P}acaya-{S}amiria {N}ational {R}eserve, {P}eru. {S}ynchronous hydrological behavior was found between the major river stems ({U}cayali and {M}aranon) and the inner rivers ({P}acaya and {S}amiria), thus enabling the utilization of water level in the main river stem to correlate with oviposition in the inner rivers. {M}ean oviposition date was {J}uly 23nd with selection of a narrow water level range (92 masl +/- 0.9 {SD}). {C}onsistent shifts towards early/late oviposition were found for years with early/late dry season onset. {E}xtreme biological shifts in terms of oviposition date onset, were identified for specific years (2004, 2010 and 2011) mainly for the extreme dry year of 2010.},
