We present an innovative framework for assessing fluvial aquatic species conservation under conditions of an impending regime shift using the case example of the Upper Colorado River Endangered Fish Recovery Program (UCREFRP). We assess the effectiveness of the program actions first, the ecoregional impact of the program second and the adaptive management paradigm in this context third, using [...]

Anticipatory responses to drought by plants: What are the environmental cues?

This study is an attempt to reconcile the physics-driven variation in reference evapotranspiration (ET0) and possible sensory-driven anticipatory acclimation that contributes to tolerance of dry weather spells and drought by plants growing in open fields. We use an original data set measured at high temporal resolution. These data include the standard meteorological observations plus detailed [...]

Seasonally variable relationships between surface water temperature and inflow in the upper San Francisco Estuary

Water temperature and inflow are key environmental drivers in aquatic systems that are linked through a causal web of factors including climate, weather, water management, and their downstream linkages. However, we do not yet fully understand the relationship between inflow and water temperature, especially in complex managed systems such as estuaries. The San Francisco Estuary is the center of a [...]
