Multi-Decadal Aspen Dynamics Show Recruitment Bottleneck Across Complex Mountain Community, Michael T. Stoddard, Kyle C. Rodman, Connor D. Crouch, David W. Huffman, Peter Z. Fulé, Kristen M. Waring, Margaret M. Moore
Aspen Bibliography
Changes in forest structure and shifts in tree species composition have occurred globally due to climate change and altered disturbance regimes. With climate trending toward warmer and drier conditions, these altered forest communities may reorganize in diverse and unpredictable ways. This is especially true in mountain environments where a range of vegetation types and abiotic conditions coexist. In this study, we used long-term permanent plot data from a site spanning broad environmental gradients to assess regeneration and mortality patterns in populations of aspen (Populus tremuloides). The study site, located on the San Francisco Peaks, Arizona, USA, is near …

Contemporary Earth crises are challenging ideologies that enthrone humans at the center of existence and separate from nature, problematizing common notions of sustainability. Further inquiry, particularly sustainability of what and for whom, requires decentering the human experience toward other-than-human beings (e.g., plants and animals). In this article, we, as the Kinship Circle book club, share reflections from our monthly dialogue with the five-part book series Kinship: Belonging in a World of Relations, built on a foundation of partnership experiences with the Keweenaw Bay Indian Community Lake Superior Band of Ojibwa. Together, we discuss three major departures from our previous modes …

Prediction Of Turfgrass Quality Using Multispectral Uav Imagery And Ordinal Forests: Validation Using A Fuzzy Approach, Alexander Hernandez, Shaun Bushman, Paul Johnson, Matthew D. Robbins, Kaden Patten
Plants, Soils, and Climate Faculty Publications
Protocols to evaluate turfgrass quality rely on visual ratings that, depending on the rater’s expertise, can be subjective and susceptible to positive and negative drifts. We developed seasonal (spring, summer and fall) as well as inter-seasonal machine learning predictive models of turfgrass quality using multispectral and thermal imagery collected using unmanned aerial vehicles for two years as a proof-of-concept. We chose ordinal regression to develop the models instead of conventional classification to account for the ranked nature of the turfgrass quality assessments. We implemented a fuzzy correction of the resulting confusion matrices to ameliorate the probable drift of the field-based …

Both topography and wildfire can exert significant influences on ecosystem processes and functions during boreal forest successions. However, their impacts on ecosystem multifunctionality (EMF) remain unclear. A mega-fire burned an area of 8700 hectares in the Great Xing’an Mountains in 2000, creating a wide range of fire severity levels across various topographic positions. This provided a unique opportunity to explore the impacts of mixed-severity fire disturbance in boreal forests. We evaluated the effect pathways of wildfire and topography on aboveground multifunctionality (AEMF), soil multifunctionality (SEMF), and overall multifunctionality (OEMF). We found that high-severity burning resulted in lower AEMF, SEMF, and …

Gains In Soil Carbon Storage Under Anthropogenic Nitrogen Deposition Are Rapidly Lost Following Its Cessation, Brooke E. Propson, Donald R. Zak, Aimée T. Classen, Andrew J Burton, Zachary B. Freedman
Michigan Tech Publications
In the Northern Hemisphere, anthropogenic nitrogen (N) deposition contributed to the enhancement of the global terrestrial carbon (C) sink, partially offsetting CO2 emissions. Across several long-term field experiments, this ecosystem-level response was determined to be driven, in part, by the suppression of microbial activity associated with the breakdown of soil organic matter. However, since the implementation of emission abatement policies in the 1970s, atmospheric N deposition has declined globally, and the consequences of this decline are unknown. Here, we assessed the response of soil C storage and associated microbial activities, in a long-term field study that experimentally increased N deposition …

The Primacy Of Density-Mediated Indirect Effects In A Community Of Wolves, Elk, And Aspen, Elaine M. Brice, Eric J. Larsen, Daniel R. Stahler, Daniel R. Macnulty
Aspen Bibliography
The removal or addition of a predator in an ecosystem can trigger a trophic cascade, whereby the predator indirectly influences plants and/or abiotic processes via direct effects on its herbivore prey. A trophic cascade can operate through a density-mediated indirect effect (DMIE), where the predator reduces herbivore density via predation, and/or through a trait-mediated indirect effect (TMIE), where the predator induces an herbivore trait response that modifies the herbivore's effect on plants. Manipulative experiments suggest that TMIEs are an equivalent or more important driver of trophic cascades than are DMIEs. Whether this applies generally in nature is uncertain because few …

Tamaulipan thornscrub forests (thornforests) have high ecological and economic values, yet over 90% of these forests have been lost, and they remain threatened, making them a conservation hotspot. For decades, federal, state, NGO, and corporate entities have been acquiring land and actively or passively restoring these forests, but results have been mixed and seldom monitored. This study characterized and quantified faunal communities of restored thornforest habitats in south Texas and examined the relationships between restored faunal communities and key site characteristics and environmental factors. We surveyed and analyzed mammal, bird, Lepidoptera, and herptile communities within 12 restored sites in the …

Oak wilt disease, caused by the fungus Bretziella fagacearum, can kill mature red oaks within months of infection, severely affecting biodiversity, landscapes, and industries. The disease, originally only present in the United States, was officially reported for the first time in Canada in June 2023. The aim of this study was to suggest a standardized assay and sample processing method to optimize oak wilt detection both in infection centers and ahead of the disease front. Two previously published molecular assays, a Nested PCR and a TaqMan qPCR, were compared to detect B. fagacearum in a variety of samples in a …

Woody biomass serves as a renewable resource for various industries, including pulp and paper production, construction, biofuels, and electricity generation. However, the molecular mechanisms behind biomass traits are poorly understood, which significantly curtails the speed and efficiency of their improvement. We used activation tagging to discover genes that can positively affect tree biomass-associated traits. We generated and screened under greenhouse conditions a population of 2,700 independent activation tagging lines. A total of 761 lines, which had significantly and positively affected at least one biomass-associated trait, were discovered. The tag was positioned in the genome for forty lines which were affected …

Understanding tree transpiration variability is vital for assessing ecosystem water-use efficiency and forest health amid climate change, yet most landscape-level measurements do not differentiate individual trees. Using canopy temperature data from thermal cameras, we estimated the transpiration rates of individual trees at Harvard Forest and Niwot Ridge. PT-JPL model was used to derive latent heat flux from thermal images at the canopy-level, showing strong agreement with tower measurements (R2 = 0.70–0.96 at Niwot, 0.59–0.78 at Harvard at half-hourly to monthly scales) and daily RMSE of 33.5 W/m2 (Niwot) and 52.8 W/m2 (Harvard). Tree-level analysis revealed species-specific responses to …

Drought is one of the important factors that cause a decrease in productivity and quality in plant cultivation. Stress tolerance in plants can be increased or damage can be reduced by various exogenous applications. One of them is flavonoids, which have an important role in the response to stress through changes that occur at the endogenous level in the plant due to drought stress. The effects of exogenous treatment of chrysin, a member of the flavonoid group, on tomato seedlings grown under water deficit were examined. Different doses (C0: Control with no treatment, C1: 0.1 mM, C2: 0.5 mM and …
