Effects of Altered Growing Season Precipitation and Management History on Aboveground Biomass Production in Tallgrass and Mixed Grass Prairie of South Dakota
… prairie; and 2) tallgrass prairie. Stationary rainout shelters were deployed to simulate 50% spring or summer rainfall reduction. 2-yr and 1-yr spring (April-June) and summer (June-August) drought regimes were used to measure resistance in 2014 and 2015 of aboveground biomass in two contrasting …

Vegetative and reproductive biomass allocation responses of herbaceous plant species to induced drought in a semi–arid highland savanna, central, Namibia
… to conserve Namibia's biodiversity. Twenty fixed rainout shelters (4 m x 4 m) were used at Neudamm Agricultural Farm to simulate drought conditions with four treatments (0%, 20%, 40%, and 80% rainfall reduction), each replicated five times. Environmental parameters, including temperature (measured …

The effects of fire and drought on plant-soil feedbacks of a nonnative invasive grass in southern Illinois
… burning and growing season drought imposed using rainout shelters. I found that invaded plots exposed to repeated burning had lower invasive grass productivity, higher root:shoot ratio, and higher C:N ratio in plant tissues and soil microbial biomass. The results presented here suggest that …

Drought Resistance and Resilience of Non-native vs. Native Grasses in the Northern Tallgrass Prairie
… grasses, and some forbs. Three automated rainout shelters at each site simulated drought conditions by intercepting rainfall. There were 8, 1-m2 study plots under each shelter and 2 addition study plots outside each shelter. Treatments in 2013 under the rainout shelters included 50%, 75%, …

Timing matters: Responses of a mesic old-field meadow to global change manipulations differed after five versus 13 years
… ON, in which factorial manipulations of water (rainout shelters and water additions), nutrient availability (NPK fertilizer additions), and herbivory (herbivore exclosures) were initiated in 2010 on 240 1 m2 plots (n = 20). Species biomass was harvested from 120 plots in 2023 and compared with …

Development of high-throughput phenotyping methods and evaluation of morphological and physiological characteristics of peanut in a sub-humid environment
… irrigated, and controlled conditions using rainout shelters to induce drought. Proximal data collection involved physiological, morphological, and yield measurements. Remote data collection was performed aerially and included collection of red-green-blue (RGB) images and canopy reflectance …

Effects of climate change on plants and ecosystem functioning : Implications for managed temperate grasslands
… are largely unknown. In addition, the rain-out shelters used to study the ecological responses to climate change (mainly drought) are often criticized for creating micro-climatological artifacts, which may influence plant responses. Thus, the main objectives of this thesis were (a) to …
