A Bayesian approach for temporally scaling climate for modeling ecological systems

Abstract: With climate change becoming more of concern, many ecologists are including climate variables in their system and statistical models. The Standardized Precipitation Evapotranspiration Index (SPEI) is a drought index that has potential advantages in modeling ecological response variables, including a flexible computation of the index over different timescales. However, little development has been made in terms of the choice of timescale for SPEI. We developed a Bayesian modeling approach for estimating the time… Show more

“…Demand to increase agricultural production has motivated the drainage of many PPR wetlands, which has been particularly focused on the drainage of smaller, more ephemeral wetlands (Dahl 1990) into larger wetlands through either surface ditches or subsurface drainage systems (i.e., 'consolidation drainage') ( Krapu et al 2004;Anteau 2012;McCauley et al 2015). Wetlands that receive drainage water have markedly greater and more stable water levels than they did before drainage (Wiltermuth 2014;McCauley et al 2015;Anteau et al 2016). Additionally, the PPR has experienced recordhigh water levels since the mid-1990s due to changes in climate and weather patterns, increasing the amount of water entering wetlands even in areas that do not have a large degree of consolidation drainage (Anteau et al 2016;McKenna et al 2017).…”

“…Wetlands that receive drainage water have markedly greater and more stable water levels than they did before drainage (Wiltermuth 2014;McCauley et al 2015;Anteau et al 2016). Additionally, the PPR has experienced recordhigh water levels since the mid-1990s due to changes in climate and weather patterns, increasing the amount of water entering wetlands even in areas that do not have a large degree of consolidation drainage (Anteau et al 2016;McKenna et al 2017). These effects of land use and climate have a synergistic interaction that increases water levels of basins until they stabilize at their basin spill point (McCauley et al 2015;Anteau et al 2016; Post van der Burg et al 2016).…”

“…We controlled for climate variation among years and wetlands with an index that was developed specifically for hydrologic effects of drought on permanent and semipermanent wetlands of the PPR Post van der Burg et al 2015). This index (hereafter drought index) was developed using the standard precipitation-evapotranspiration index (Beguería and Vicente-Serrano 2012).…”

“…We calculated the index with monthly precipitation and temperature from the parameter-elevation regressions on independent slopes model (PRISM Climate Group-Oregon State University 2014). We used a weighted average of the previous 10 years of monthly climate data to best approximate the influence of drought on wetland water surface areas Post van der Burg et al 2015). Drought index values for our focal wetlands ranged from À2.2 to 2.4, with negative values indicating drier conditions and positive values indicating wetter conditions.…”
