Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman
Permafrost Hydrology Drives The Assimilation Of Old Carbon By Stream Food Webs In The Arctic, Jonathan A. O’Donnell, Michael P. Carey, Joshua C. Koch, Xiaomei Xu, Brett A. Poulin, Jennifer Walker, Christian E. Zimmerman
United States National Park Service: Publications
Permafrost thaw in the Arctic is mobilizing old carbon (C) from soils to aquatic ecosystems and the atmosphere. Little is known, however, about the assimilation of old C by aquatic food webs in Arctic watersheds. Here, we used C isotopes (d13C, D14C) to quantify C assimilation by biota across 12 streams in arctic Alaska. Streams spanned watersheds with varying permafrost hydrology, from ice-poor bedrock to ice-rich loess (that is, yedoma). We measured isotopic content of (1) C sources including dissolved organic C (DOC), dissolved inorganic C (DIC), and soil C, and (2) stream biota, including benthic biofilm and macroinvertebrates, and …

Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (y). In contrast, long-term (≥10 y) experiments show increasing community …

Theatre & The Environment: Cross-Cultural Exchange Through Travel And Performance Activism, Betel Solomon Tesfamariam
Theatre & The Environment: Cross-Cultural Exchange Through Travel And Performance Activism, Betel Solomon Tesfamariam
EnviroLab Asia
Performance activism, collaborative and cross-cultural, were keys to the success of EnviroLab Asia's clinic trip to Thailand in May 2018. Working with peers in Thai universities, this writer reflects on the degree to which her immersion in local environmental struggles in Thailand, and the compelling theater project that grew out of it, also has helped her understand some of the same pressures that confront her home communities in Africa.

Familiarity & Unfamiliarity, Luyi Huang
EnviroLab Asia
During the May 2018 EnviroLab Clinic Trip to Thailand, and as part of the performance group, the author encountered an important linguistic barrier. Because the Thai and US-based dancers did not know each other's language, they had to learn to trust each other's body language as their form of communication. The unfamiliar became familiar.

Cave Temperature And Management Implications In Lehman Caves, Great Basin National Park, Usa, Stanka Šebela, Gretchen Baker, Barbara Luke
Cave Temperature And Management Implications In Lehman Caves, Great Basin National Park, Usa, Stanka Šebela, Gretchen Baker, Barbara Luke
KIP Articles
Cave air temperature was measured at six locations in Lehman Caves (USA) for one year at hourly intervals. Lehman is a show cave in a national park, treasured for its geological and biological resources. The two monitoring locations that are off of the tour route and, also, relatively distant from the cave’s entrances displayed nearly constant air temperature during the year. The other four sites, along the tour route, show daily temperature variation as well as annual fluctuation. After visitation levels decreased in the autumn, cave temperatures lagged but eventually reached an equilibrium which demonstrates recovery in the quiet winter. …
A Geomorphic Enthalpy Method: Description And Application To The Evolution Of Fluvial-Deltas Under Sea-Level Cycles, William Anderson, Jorge Lorenzo Trueba, Vaughan Voller
A Geomorphic Enthalpy Method: Description And Application To The Evolution Of Fluvial-Deltas Under Sea-Level Cycles, William Anderson, Jorge Lorenzo Trueba, Vaughan Voller
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Fluvial deltas are composites of two primary sedimentary environments: a depositional fluvial region and an offshore region. The fluvial region is defined by two geomorphic moving boundaries: an alluvial-bedrock transition (ABT), which separates the sediment prism from the non-erodible bedrock basement, and the shoreline (SH), where the delta meets the ocean. The trajectories of these boundaries in time and space define the evolution of the shape of the sedimentary prism, and are often used as stratigraphic indicators, particularly in seismic studies, of changes in relative sea level and the identification of stratigraphic sequences. In order to better understand the relative …

Disinfection Byproduct Formation During Drinking Water Treatment And Distribution: A Review Of Unintended Effects Of Engineering Agents And Materials, Shunke Ding, Yang Deng, Tom Bond, Chao Fang, Zhongqi Cao, Wenhai Chu
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Unintended effects of engineering agents and materials on the formation of undesirable disinfection byproducts (DBPs)during drinking water treatment and distribution were comprehensively reviewed. Specially, coagulants, biologically active filtration biofilms, activated carbons, nanomaterials, ion-exchange resins, membrane materials in drinking water treatment and piping materials, deposits and biofilms within drinking water distribution systems were discussed, which may serve as DBP precursors, transform DBPs into more toxic species, and/or catalyze the formation of DBPs. Speciation and quantity of DBPs generated rely heavily on the material characteristics, solution chemistry conditions, and operating factors. For example, quaternary ammonium polymer coagulants can increase concentrations of N-nitrosodimethylamine …

Determination Of Soil Properties And Fungal Interrelations Influenced By Forest Restoration On A Contaminated Zinc Mining Area, Chutima Kantrong, Kallaya Suntornvongsakul, Yang-Soo Lee
Applied Environmental Research
Forest restoration in a contaminated zinc mining area must take into account the environmental soil properties. This study aimed to analyze the soil properties from the three different stages of restored forests, at 3, 7 and 17, focusing on the impact on soil microorganismsand availability of fungal species. Three study sites were selected, all located in a zinc mining area in Mae Sot District, Tak Province, Thailand. The results showed that observed soil properties especially soil texture,moisture and nutrients differed between stand initiation and regrowth forests and affected the distribution of fungal species. Soils in older forest stands up to …

Applied Environmental Research
Microbial-derived surface-active compounds (biosurfactants) have attracted attention due to their low toxicity, cost-effectiveness, biodegradable nature and environment compatibility. Due to paucity of knowledge in the production of biosurfactant by microorganisms from other sources such as biochar-amended soil, the present study investigates the potential of rhizospheric bacteria isolated from biochar amended soil of okra plant in the production of biosurfactants using different recovery techniques. Rhizospheric bacteria were screened for biosurfactant productionusing Haemolytic, Oil spreading, Drop collapse, Methylene blue method, Bacterial adhesion to hydrocarbon and Emulsification activity. The biosurfactant was extracted using different extraction solvents (acid precipitation, ethyl acetate, acetone, dichloromethane and …
Trophic Models Of Seagrass Ecosystems In Maqueda Channel, Caramoan Peninsula, Philippines, Michael A. Clores, Michael A. Cuesta
Trophic Models Of Seagrass Ecosystems In Maqueda Channel, Caramoan Peninsula, Philippines, Michael A. Clores, Michael A. Cuesta
Applied Environmental Research
Steady-state trophic models were constructed using the Ecopath with Ecosim software to examine the general status, development trends, and functional integrity of three extensive seagrass meadows located in Maqueda Channel of Caramoan Peninsula, Southern Luzon Island, Philippines. The results show that the ecosystems are composed of 23-24 functional groups with effective trophic levels extending from 1.00 to 3.76. Mixed trophic impacts show that decrease in the biomass of grazers Tripneustes gratilla (collector urchin) had a positive impact on the biomass of seagrasses. On the other hand, a positive effect on the benthic groups is expected with an assumed decrease in …
