The magnitude of future climate change depends substantially on the greenhouse gas emission pathways we choose. Here explore implications highest and lowest Intergovernmental Panel Climate Change emissions for associated impacts in California. Based projections from two state-of-the-art models with low medium sensitivity (Parallel Model Hadley Centre Model, version 3, respectively), find that annual temperature increases nearly double lower B1 to higher A1fi scenario before 2100. Three four...
Two foundational questions about sustainability are “How ecosystems and the services they provide going to change in future?” do human decisions affect these trajectories?” Answering requires an ability forecast ecological processes. Unfortunately, most forecasts focus on centennial-scale climate responses, therefore neither meeting needs of near-term (daily decadal) environmental decision-making nor allowing comparison specific, quantitative predictions new observational data, one strongest...
The hydraulic limitation hypothesis (Ryan and Yoder 1997) proposes that leaf-specific conductance (k1) stomatal (gs) decline as trees grow taller, resulting in decreased carbon assimilation. We tested the by comparison of canopy-dominant Douglas-fir (Pseudotsuga menziesii var. menziesii) stands were approximately 15 m (20 years old), 32 (40 old) 60 (> 450 tall Wind River, Washington, USA. Carbon isotope discrimination (Δ) declined with tree height (18.6, 17.6 15.9% for 15, tall,...
Abstract The National Ecological Observatory Network (NEON) is a multidecadal and continental-scale observatory with sites across the United States. Having entered its operational phase in 2018, NEON data products, software, services become available to facilitate research on impacts of climate change, land-use invasive species. An essential component are 47 tower sites, where eddy-covariance (EC) sensors operated determine surface–atmosphere exchange momentum, heat, water, CO 2 . EC...
ABSTRACT Nitrogen‐fixing epiphytes (especially lichens with a cyanobacterial symbiont—cyanolichens) have the potential to contribute significant amounts of nitrogen (N) montane tropical forests, which are typically low in N—but factors controlling abundance and distribution epiphytic cyanolichens poorly understood. In long‐term fertilization experiments forests on 4.l million‐yr‐old Oxisol island Kauà'i 152‐yr‐old lava flow Hawai'i, cyanolichen Pseudocyphellaria crocata increased...
The net exchanges of carbon dioxide, water vapor, and energy were examined in a perennial Colorado Plateau grassland for 5 years. study began within multiyear drought continued as the ended. is located near northern boundary influence North American monsoon, major climatic feature bringing summer rain. Following rain, evapotranspiration peaked above 8 mm d −1 but was usually much smaller (2–4 ). Net productivity low compared to other ecosystems, with peak hourly CO 2 uptake spring 4 μ mol m...
Summary Populations of Metrosideros polymorpha establish across a broad range precipitation in Hawai‘i – from <400 to >10000 mm per year. To determine whether adjustment hydraulic and photosynthetic traits could contribute this success both high low rainfall, we sampled populations on the wet dry sides Island, replicated two different‐aged lava flows at similar elevation mean annual temperature. We quantified 24 stem leaf an integrated study hydraulics, gas exchange, chemistry anatomy....
Abstract The National Ecological Observatory Network (NEON) provides over 180 distinct data products from 81 sites (47 terrestrial and 34 freshwater aquatic sites) within the United States Puerto Rico. These include both field remote sensing collected using standardized protocols sampling schema, with centralized quality assurance control (QA/QC) provided by NEON staff. Such breadth of creates opportunities for research community to extend basic applied while also extending impact reach...
Ecological studies require quality data to describe the nature of ecological processes and advance understanding ecosystem change. Increasing access big has magnified both burden complexity ensuring data. The costs errors in ecology include low use data, increased time spent cleaning poor reproducibility that can result a misunderstanding dynamics, all which erode efficacy trust research. Although conceptual technological advances have improved management, cultural shift is needed embed as...
An increasing number of network observatories have been established globally to collect long-term biogeochemical data at multiple spatial and temporal scales. Although many outstanding questions in biogeochemistry would benefit from science, the ability earth- environmental-sciences community conduct synthesis studies within across networks is limited seldom done satisfactorily. We identify ideal characteristics networks, common problems with using data, key improvements strengthen intra-...
Abstract The combination of continuing anthropogenic impact on ecosystems across the globe and observation catastrophic shifts in some systems has generated substantial interest understanding predicting ecological tipping points. recent establishment full operation NEON created an opportunity for researchers to access extensive datasets monitoring composition functioning a wide range ecosystems. These data may be uniquely effective studying regime points because their long time horizon,...
Abstract The COVID‐19 pandemic significantly impacted undergraduate education and fundamentally altered the structure of course delivery in higher education. In field‐based biology ecology courses, where instructors students typically work collaboratively in‐person to collect data, this has been particularly challenging. context, faculty from Ecological Research as Education Network (EREN) collaborated with National Observatory (NEON) design five free‐flexible learning projects for use by...
