Plant Responses to Temperature and Water Limitation Active
Weather and climate impacts on dominant native perennials must be understood in order to efficiently manage our western landscapes. We use an ecophysiological approach, linking to population, community, and landscape ecology, to understand the impacts and responses of plants on or to their environment.

Filter Total Items: 28Microbial community responses to 17 years of altered precipitation are seasonally dependent and coupled to co-varying effects of water content on vegetation and soil C
Precipitation amount and seasonal timing determine the duration and distribution of water available for plant and microbial activity in the cold desert sagebrush steppe. In this study, we sought to determine if a sustained shift in the amount and timing of precipitation would affect soil microbial diversity, community composition, and soil carbon (C) storage. Field plots were irrigated (+200 mm) dAuthorsPatrick O. Sorensen, Matthew J. Germino, Kevin P. FerisDesert shrub responses to experimental modification of precipitation seasonality and soil depth: relationship to the two-layer model and ecohydrological niche
1. Ecohydrological niches are important for understanding plant community responses to climate shifts, particularly in dry lands. According to the two-layer hypothesis, selective use of deep-soil water increases growth or persistence of woody species during warm and dry summer periods and thereby contributes to their coexistence with shallow-rooted herbs in dry ecosystems. The resource-pool hypothAuthorsMatthew J. Germino, Keith ReinhardtRemote sensing of sagebrush canopy nitrogen
This paper presents a combination of techniques suitable for remotely sensing foliar Nitrogen (N) in semiarid shrublands – a capability that would significantly improve our limited understanding of vegetation functionality in dryland ecosystems. The ability to estimate foliar N distributions across arid and semi-arid environments could help answer process-driven questions related to topics such asAuthorsJessica J. Mitchell, Nancy F. Glenn, Temuulen T. Sankey, DeWayne R. Derryberry, Matthew J. GerminoWarming and the dependence of limber pine (Pinus flexilis) establishment on summer soil moisture within and above its current elevation range
Continued changes in climate are projected to alter the geographic distributions of plant species, in part by affecting where individuals can establish from seed. We tested the hypothesis that warming promotes uphill redistribution of subalpine tree populations by reducing cold limitation at high elevation and enhancing drought stress at low elevation. We seeded limber pine (Pinus flexilis) into pAuthorsAndrew B. Moyes, Cristina Castanha, Matthew J. Germino, Lara M. Kueppers - News
