“…Further, this approach has applicability to predicting abrupt demographic events for plants. In addition to other climatic extremes such as freezing for trees (Cavanaugh et al 2015) or for crops (Vico et al 2014), other example climatic interactions besides drought and warming (Adams et al 2009) include drought and change in depth to groundwater for oaks (Brown et al 2018), flooding and drought for mangroves (Miao et al 2009), and rainfall and temperature for germination in desert annuals (referred to as hydrothermal time; Kimball et al 2011;Huang et al 2016).…”

The occurrence of plant species around the globe is largely constrained by climate. Ecologists use plant-climate relationships such as bioclimatic envelopes to determine environmental conditions promoting probable species occurrence. Traditional bioclimatic envelopes exclude disturbance or include disturbance as infrequent and small scale effects, assuming that the net effect of climate on demographic processes predicts longer-term equilibrial responses of biota. Due to increasing frequency and extent of extreme events associated with climate change, ecologists may need to increase focus on individual demographic events driven by extreme events such as large-scale tree die-off. Existing approaches that predict traditional equilibrial biogeographic responses associated with long-term trends in mean climate could be complemented with an expanded focus on how extreme events catalyze individual demographic events. Extreme conditions of drought are often a prerequisite for abrupt demographic events such as large-scale tree die-off, with effects of extremes often exacerbated by climatic trends such as warming. In this PERSPECTIVE, we illustrate the use of bioclimatic envelopes for predicting individual demographic events. Currently, data on conditions that drive individual demographic events are usually aggregated across time and/or are correlative. We highlight this approach with a case study of experimentally drought-induced mortality in Pinus edulis trees resulting from a combination of ecologically extreme conditions in one parameter and a shifting distribution in another: drought under higher temperatures. Based on this example, we predict a more than five-fold increase in the frequency of die-off events under a global change scenario of high emissions. This general approach complements traditional bioclimatic envelopes, and more detailed physiological approaches currently being refined to address climate change challenges. Notably, this approach could be developed for other climate conditions and plant species, and may improve predictions of abrupt demographic events that are altering ecosystems globally.

“…Planting around 1 September resulted in higher GDD but led to poor winter survival in 2010–2011 (1819) and 2011–2012 at St. Paul (1620). Excessive GDD may lead to growth beyond the ideal winter acclimation condition and negatively impact winter survival (Vico et al, 2014). In addition, lower winter survival for early planting dates may be attributed to increased exposure to diseases such as barley yellow dwarf virus (McGrath and Bale, 1990; Nleya and Rickertsen, 2014).…”

No planting date from early September to mid-October consistently resulted in maximum winter survival.• Two key environmental variables, fall growing degree days and snow cover at or below -4°F contributed to winter survival.• The cultivar McGregor had the highest winter survival and grain yield among the cultivars tested.• Winter survival was positively associated with grain yield.• Additional research and breeding for winter hardiness will be needed to improve winter survival and grain yield. AbstractWinter barley (Hordeum vulgare L.) is currently being developed as a new cash crop with potential to provide both economic and environmental benefits in Minnesota. In a field experiment, three winter barley cultivars that exhibited different levels of winter hardiness were sown at four planting dates (early September to mid-October with a ~2-week interval between each planting date) in St. Paul from 2010-2013 and 2015-2018 and in Lamberton from 2015-2019. Fall growing degree days (GDD), winter snow coverage, winter survival, and grain yield were evaluated across 10 site-years. Only 50% of siteyears had a winter survival at 20% or greater when averaged across all planting dates and cultivars. No specific planting date consistently resulted in maximum winter survival. McGregor, a non-malting barley, had the highest winter survival and yield. Planting dates that resulted in fall-accumulated GDD from 600 to 1400 were associated with better winter survival in years with sufficient snow cover. Less than 4 inches of snow cover and temperatures at or below -4°F for more than 3 days led to poor winter survival in 5 of the 10 site-years. Continued breeding for improved winter hardiness and agronomic research that provides best management practices will be needed to develop a practical winter barley cropping system for Minnesota.

“…Vico, Hurry, and Weih () found that a decrease in LT 50c increased the survival rate and decreased the interannual variability in survival rate for a cultivar. This is also confirmed by the present results, where the most frost tolerant cultivar Ceylon (LT 50c : −23°C) survived at all the 13 Swedish locations in 2011/12, while Ellvis (LT 50c : −22°C), Frontal (LT 50c : −20°C), Kepler (LT 50c : −18°C) and Pentadur (LT 50c : −16°C) survived at 92%, 77%, 62% and 31% of the locations, respectively.…”
