Fungal communities can influence the productivity, composition, and survival of trees through cycling nutrients, providing resources, and altering pathogens. Thus, shifts in fungal communities could impact forests by altering interactions between trees and their environments. Fungal community composition may be shaped by stochastic and deterministic processes such as dispersal-limitation, environmental filtering, and partner specificity between trees and fungi. For tree species with large geographic ranges, we expect fungal assembly processes to change with environmental variation across the range of the tree partner. Due to specificity between trees and symbiotic fungi, we expect deterministic to outweigh stochastic processes in root compared ...


Ecosystem Service Values Of Gardens In The Yellow River Basin, China, Ge Qianqian, Xu Wenjie, Fu Meichen, Han Yingxin, An Guoqiang, Xu Yuetong Apr 2022

Ecosystem Service Values Of Gardens In The Yellow River Basin, China, Ge Qianqian, Xu Wenjie, Fu Meichen, Han Yingxin, An Guoqiang, Xu Yuetong

Journal of Arid Land

Studies on the ecosystem service value (ESV) of gardens are critical for informing evidence- based land management practices based on an understanding of the local ecosystem. By analyzing equivalent value factors (EVFs), this paper evaluated the values of 11 ecosystem services of gardens in the Yellow River Basin of China in 2019. High-precision land use survey data were used to improve the accuracy of the land use classification, garden areas, and spatial distribution of the ESVs of gardens. The results showed that garden ecosystem generally had high ESVs, especially in terms of the ESV of food production, which is worthy ...

3d Library From Body Size From Unconventional Specimens: A 3d Geometric Morphometrics Approach To Fishes From Ancestral Pueblo Contexts, Jonathan Dombrosky, Thomas F. Turner, Alexandra Harris, Emily Lena Jones Apr 2022

3d Library From Body Size From Unconventional Specimens: A 3d Geometric Morphometrics Approach To Fishes From Ancestral Pueblo Contexts, Jonathan Dombrosky, Thomas F. Turner, Alexandra Harris, Emily Lena Jones

Anthropology Faculty & Staff Publications

Animal body size estimation from zooarchaeological specimens often relies on specific, one-dimensional (i.e., conventional) measures from skeletal elements. Here, we introduce an animal body size estimation technique for archaeological fishes that relies on 3D reference scans and the calculation of centroid size, a standard 3D geometric morphometric proxy measure for organism size. Centroid size-based estimations on whole caudal vertebrae are strongly correlated with a widely accepted measure (i.e., centrum width), but the scalability and flexibility of the centroid size-based approach allows for use on a wide variety of fragmented remains. We use zooarchaeological fish remains (subfamily Ictiobinae) from ...

Plant-Soil Feedbacks Help Explain Plant Community Productivity, Andrew Kulmatiski, Jeanette Norton, Leslie E. Forero, Josephine Grenzer Mar 2022

Plant-Soil Feedbacks Help Explain Plant Community Productivity, Andrew Kulmatiski, Jeanette Norton, Leslie E. Forero, Josephine Grenzer

Browse all Datasets

Plant community productivity tends to increase as species richness increases, but the mechanisms behind this biodiversity-productivity relationship are not fully understood. Plant-soil feedbacks (PSF) are a compelling potential mechanism of the biodiversity-productivity relationship because they can explain patterns of both underyielding and overyielding in diverse plant communities. To test the role of plant-soil feedbacks in the biodiversity-productivity relationship we measured all possible plant-soil feedbacks for sixteen species, and used the measured plant-soil feedbacks to predict plant community biomass production. We compared the predicted plant community biomass production to observed biomass production in a paired biodiversity-productivity experiment.

Pando Aspen 2021 Remeasure, Paul C. Rogers

Browse all Datasets

Upland aspen (Populus spp.) forests contribute significantly to biodiversity in their circumboreal role as keystone species. The 43-hectare Pando aspen (Populus tremuloides Michx.) clone in Utah, USA, is thought to be the largest living organism on earth, but is faltering due to chronic herbivory. Long-term resilience in aspen communities, including Pando, rests on successful recruitment of vegetative suckers. This is the first trend assessment of this threatened iconic forest using a vital indicators approach. I examined 64 plots using 19 indicators to determine current conditions. Findings show that a genetically uniform Pando is 'breaking up' because of herbivory fencing. Initial ...

Spatial Variability Of Leaf Wetness Under Different Soil Water Conditions In Rainfed Jujube (Ziziphus Jujuba Mill.) In The Loess Hilly Region, China, Gao Zhiyong, Wang Xing Feb 2022

Spatial Variability Of Leaf Wetness Under Different Soil Water Conditions In Rainfed Jujube (Ziziphus Jujuba Mill.) In The Loess Hilly Region, China, Gao Zhiyong, Wang Xing

Journal of Arid Land

Leaf wetness provides a wide range of benefits not only to leaves, but also to ecosystems and communities. It regulates canopy eco-hydrological processes and drives spatial differences in hydrological flux. In spite of these functions, little remains known about the spatial distribution of leaf wetness under different soil water conditions. Leaf wetness measurements at the top (180 cm), middle (135 cm), and bottom (85 cm) of the canopy positions of rainfed jujube (Ziziphus jujuba Mill.) in the Chinese loess hilly region were obtained along with meteorological and soil water conditions during the growing seasons in 2019 and 2020. Under soil ...

Spatiotemporal Variation Of Forest Land And Its Driving Factors In The Agropastoral Ecotone Of Northern China, Wang Shiqing, Tao Zefu, Sun Piling, Chen Sijia, Sun Huiying, Li Nan

Journal of Arid Land

As an important natural resource, forest land plays a key role in the maintenance of ecological security. However, variations of forest land in the agropastoral ecotone of northern China (AENC) have attracted little attention. Taking the AENC as an example and based on remote-sensing images from 2000, 2010 to 2020, we explored the spatiotemporal variation of forest land and its driving factors using the land-use transfer matrix, spatial autocorrelation analysis and spatial error model. The results showed that from 2000 to 2020, the total area of forest land in the AENC increased from 75,547.52 to 77,359.96 ...

Data From: Glucose Tolerance Of Iguanas Is Affected By High Sugar Diets In The Lab And Supplemental Feeding By Ecotourists In The Wild, Susannah S. French Jan 2022

Data From: Glucose Tolerance Of Iguanas Is Affected By High Sugar Diets In The Lab And Supplemental Feeding By Ecotourists In The Wild, Susannah S. French

Browse all Datasets

Physiological responses to both natural and anthropogenic perturbations involve changes in glucose use and metabolism to enable animals to respond to challenges. The responses are at least partially mediated via the glucocorticoids, and the proper functioning of these systems are critical to animal health. Prolonged high-sugar diets in humans can compromise physiological functions and lead to a range of diseases including diabetes. Such outcomes are less common in natural, non-human systems, likely because of evolutionarily based balances between sugar intake and the ability to process it. Due to both landscape changes and human feeding of wildlife, the introduction of unnatural ...

Laurentian Great Lakes Warming Threatens Northern Fruit Belt Refugia, Robert Warren Jan 2022

Laurentian Great Lakes Warming Threatens Northern Fruit Belt Refugia, Robert Warren

Biology Faculty Datasets

Climate refugia are anomalous ‘pockets’ of spatially or temporally disjunct environmental conditions that buffer distinct flora and fauna against prevailing climatic conditions. Physiographic landscape features, such as large water bodies, can create these micro-to-macro-scale terrestrial habitats, such as the prevailing westerly winds across the Laurentian Great Lakes that create relatively cooler leeward conditions in spring and relatively warmer leeward conditions in autumn. The leeward Great Lakes climate effects create a refugia (popularly known as a ‘fruit belt’) favorable for fruit-bearing trees and shrubs. This fruit belt refugia owes its existence to seasonal inversions whereby spring cooling prevents early flower budding ...

NRM Departmental Data Sets

Previously published work used program MARK to estimate parameters for multistate models for Bighead Carp (Hypophthalmichthys nobilis) and Silver Carp (H. molitrix) (Coulter et al. 2018) movements in the Illinois River. Multistate models estimate transition probability (psi), survival probability (S), and detection probability (p) and models with those parameters varying by state and time (state*time), just state (state), just time (time), and neither (.) were evaluated for each species (Coulter et al. 2018). Using the format of the top model for each species identified in Coulter et al. (2018), Markov Chain Monte Carlo (MCMC) methods were used to provide a ...

Dataset For: Mapping Fire History And Quantifying Burned Area Through 35 Years Of Prescribed Fire History At An Illinois Tallgrass Prairie Restoration Site Using Gis, Erin G. Rowland-Schaefer, Elizabeth M. Bach, Bill P. Kleiman, Holly P. Jones

Research Datasets

Fire was important to pre-colonization prairies. In today’s remnant and reconstructed prairies, managers frequently employ prescribed fire, a historical management practice that limits woody encroachment, suppresses non-native species, and promotes nutrient cycling. However, few long-term prescribed fire spatial datasets are available for study. We used archived images of prescribed fire maps and hand-drawn fire records to generate a geospatial record of the prescribed fire history at Nachusa Grasslands, a combination remnant and restored preserve in northern Illinois. This record contains maps of the prescribed fire history of the preserve across the entirety of its 35-year history. We used the ...
