Empirical Evidence For The Scale Dependence Of Biotic Interactions, Jonathan Belmaker, Phoebe Zarnetske, Sara Zonneveld, Sydne Record, Angela L. Strecker, Lydia Beaudrot

Environmental Science and Management Faculty Publications and Presentations

Aim: Although it is recognized that ecological patterns are scale dependent, the exact scales over which specific ecological processes operate are still a matter of controversy. In particular, understanding the scales over which biotic interactions operate is critical for predicting changes in species distributions in the face of the ongoing biodiversity crisis. It has been hypothesized that biotic interactions operate predominately at fine grains, yet this conjecture has received relatively little empirical scrutiny. We use US woodpeckers as a model system to assess the relative importance of biotic interactions, environmental suitability and geographic proximity to other intraspecific occurrence sites, …

Gouldian Finch Breeding Surveys 2015: Ord-East Kimberley Expansion Project - Weaber Plain Development Area, Sarah R. Pryke

Irrigated Agricultural Development in the North

As part of the requirement for State approval under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and the Gouldian Finch Management Plan (GFMP), a baseline assessment and on-going monitoring of the endangered Gouldian finch (Erythrura gouldiae) is required during the construction and operation of the Ord River Irrigation Area Weaber Plain Development Project in the eastern Kimberley, Western Australia. This report details the findings from surveys of Gouldian finches during their annual breeding season (2015).

Iron-Mediated Stabilization Of Soil Carbon Amplifies The Benefits Of Ecological Restoration In Degraded Lands, Lucas C. R. Silva, Timothy A. Doane, Rodrigo S. Correa, Vinicius Valverde, Engil Isadora Pujol Pereira, William R. Horwath

School of Earth, Environmental, & Marine Sciences Faculty Publications

Recent observations across a 14‐year restoration chronosequence have shown an unexpected accumulation of soil organic carbon in strip‐mined areas of central Brazil. This was attributed to the rapid plant colonization that followed the incorporation of biosolids into exposed regoliths, but the specific mechanisms involved in the stabilization of carbon inputs from the vegetation remained unclear. Using isotopic and elemental analyses, we tested the hypothesis that plant‐derived carbon accumulation was triggered by the formation of iron‐coordinated complexes, stabilized into physically protected (occluded) soil fractions. Confirming this hypothesis, we identified a fast formation of microaggregates shortly after the application of iron‐rich biosolids, …

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Despite major anthropogenic modification to the Missouri River system, relative abundance of five shiner species within Nebraska’s reach of the Missouri River has increased since the 1940’s. The combined abundance of five species: Red Shiner Cyprinella lutrensis, Spotfin Shiner C. spilopterus, Emerald Shiner Notropis atherinoides, River Shiner N. blennius, Sand Shiner N. stramineus, represented > 50% of the small fish community in the Missouri River over the past ten years (2003-2012). More than 3,600 mini-fyke nets were deployed, resulting in over 158,600 shiners collected from the Missouri River along Nebraska’s eastern border between 2003 and 2012. Past literature …

Nutrient Addition Effects On Tropical Dry Forests: A Mini-Review From Microbial To Ecosystem Scales, Jennifer S. Powers, Kristen K. Becklund, Maria G. Gei, Siddharth B. Iyengar, Rebecca Meyer, Christine S. O'Connell, Erik M. Schilling, Christina M. Smith, Bonnie G. Waring, Leland K. Werden

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Humans have more than doubled inputs of reactive nitrogen globally and greatly accelerated the biogeochemical cycles of phosphorus and metals. However, the impacts of increased element mobility on tropical ecosystems remain poorly quantified, particularly for the vast tropical dry forest biome. Tropical dry forests are characterized by marked seasonality, relatively little precipitation, and high heterogeneity in plant functional diversity and soil chemistry. For these reasons, increased nutrient deposition may affect tropical dry forests differently than wet tropical or temperate forests. Here, we review studies that investigated how nutrient availability affects ecosystem and community processes from the microsite to ecosystem scales …

Collecting Multiple Data Points In A Thunderstorm Environment, Matthew Nelson

2017 Academic High Altitude Conference

Collecting multiple data points in adverse conditions such as a thunderstorm presents a number of challenges in collecting and relaying data. Wireless sensor mesh networks is a proven method for extracting and relaying data in radio environments that may either be roving, in adverse conditions or both. This paper explores using wireless sensor mesh networks to collect atmospheric data that is present in a thunderstorm system to enable researchers to learn more from these systems. A wireless sensor mesh network is ideal since it is well suited for both moving and sensor nodes that are in adverse RF conditions. A …

Using A High Altitude Balloon Platform To Observe And Measure Seasonal Ozone Flux Over Agricultural Landscapes, Cody Sabo

2017 Academic High Altitude Conference

The concentration of greenhouse gasses (GHGs) in the atmosphere has continued to rise since the industrial era. This issue has had a multitude of negative impacts on all living things. Among the major GHGs are carbon dioxide, methane, nitrous oxide, and ozone. Ozone is of particular importance because it not only has the ability to trap heat in the atmosphere, but it also directly impacts organisms by causing harm to both plants and humans. The damage that ozone causes to plants is most closely linked to ozone uptake rather than ozone concentration. So, measuring ozone uptake is becoming critical for …

Using An Obcd Approach And Landsat Tm Data To Detect Harvesting On Nonindustrial Private Property In Upper Michigan, Riccardo Tortini, Audrey L. Mayer, Pieralberto Maianti

College of Forest Resources and Environmental Science Publications

Forest dynamics influence climate, biodiversity, and livelihoods at multiple scales, yet current resource policy addressing these dynamics is ineffective without reliable land use land cover change data. The collective impact of harvest decisions by many small forest owners can be substantial at the landscape scale, yet monitoring harvests and regrowth in these forests is challenging. Remote sensing is an obvious route to detect and monitor small-scale land use dynamics over large areas. Using an annual series of Landsat-5 Thematic Mapper (TM) images and a GIS shapefile of property boundaries, we identified units where harvests occurred from 2005 to 2011 using …

Contrasting Environmental Drivers Of Adult And Juvenile Growth In A Marine Fish: Implications For The Effects Of Climate Change, Joyce Jia Lin Ong, Adam Nicholas Rountrey, Jessica Jane Meeuwig, Stephen J. Newman, Jens Zinke, Mark Gregory Meekan

Fisheries Research Articles

Many marine fishes have life history strategies that involve ontogenetic changes in the use of coastal habitats. Such ontogenetic shifts may place these species at particular risk from climate change, because the successive environments they inhabit can differ in the type, frequency and severity of changes related to global warming. We used a dendrochronology approach to examine the physical and biological drivers of growth of adult and juvenile mangrove jack (Lutjanus argentimaculatus) from tropical north-western Australia. Juveniles of this species inhabit estuarine environments and adults reside on coastal reefs. The Niño-4 index, a measure of the status of …

Direct Atmospheric Evidence For The Irreversible Formation Of Aqueous Secondary Organic Aerosol, Marwa M. El-Sayed, Yingqing Wang, Christopher J. Hennigan

Publications

The reversible nature of aqueous secondary organic aerosol (aqSOA) formation was characterized for the first time through direct atmospheric measurements. Water-soluble organic carbon in the gas and particle phases (WSOCg and WSOCp) was measured simultaneously to quantify aqSOA formation in Baltimore, Maryland. During the nighttime, aqSOA formation was evident as WSOCg increasingly partitioned to the particle phase with increasing relative humidity (RH). To characterize the reversible/irreversible nature of this aqSOA, the WSOCp measurement was alternated through an unperturbed ambient channel and through a “dried” channel maintained at ~40% RH (with 7 s residence time) to mimic the natural drying particles …

An Analysis Of Juvenile Chinook Salmon Outmigration Speed And Survival In Response To Habitat Features: Sacramento River From Knights Landing To Sacramento, California, Natalie N. Mcnair

Master's Theses

Outmigration is an important life stage for Chinook salmon (Oncorhynchus tshawytscha) survival in the Sacramento River, and yet our understanding of their behavior and needs during this time is limited. To gain a better understanding of their survival and movement rates during outmigration, late fall run Chinook salmon smolts were tracked using acoustic telemetry techniques. Habitat features were measured and quantified throughout the study area to evaluate how Chinook salmon respond to key levee features including shade, instream woody material, and aquatic vegetation. The overall average movement speed through the entire study area was 0.77 m/s with an …

Blow-Up Of Positive Solutions To Wave Equations In High Space Dimensions, Mohammad A. Rammaha, Hiroyuki Takamura, Hiroshi Uesaka, Kyouhei Wakasa

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

This paper is concerned with the Cauchy problem for the semilinear wave equation:

utt - u = F(u) in Rn X [0;1);

where the space dimension n >2, F(u) = jujp or F(u) = up-1u with p>1. Here, the Cauchy data are non-zero and non-compactly supported. Our results on the blow-up of positive radial solutions (not necessarily radial in low dimensions n=2,3) generalize and extend the results of Takamura [19] for zero initial position and Takamura, Uesaka and Wakasa [21] for zero intitial velocity. The main technical difficulty in the paper lies in obtaining the lower bounds for for …

Detecting Change In Central California Coast Coho Salmon Habitat In Scotts Creek, California, From 1997–2013, Ashley Brubaker Hillard

Master's Theses

Scotts Creek, in Santa Cruz County, Calif., supports the southernmost extant population of Coho Salmon (Oncorhynchus kisutch) in North America. In 1997, the California Department of Fish and Game (now Fish and Wildlife) conducted an extensive habitat typing survey of mainstem Scotts Creek, describing all habitat units from the top of the estuary to the limit of anadromy approximately 12 km upstream. I repeated this survey in 2013 to (1) assess changes in the quantity and quality of instream habitat, (2) compare the current condition to goals and standards established in the federal Central California Coast (CCC) Coho …

Ecodistricts In San Francisco: The Implementation Of Neighborhood Regional Planning And Its Potential Effects On Environmental Resilience, Elizabeth M. Juvera

Master's Projects and Capstones

Ecodistricts, or neighborhood-scale, community-driven areas of sustainable development, have emerged internationally and within the U.S. to create models of adaptive environmental design and advanced urban infrastructure. Central SoMa is the first ecodistrict to be planned and implemented in San Francisco, with the intention of revitalizing and greening this urbanized region of the city. At this time, the Central SoMa area has very low biodiversity levels, inefficient infrastructure, and poor water management capabilities. Through the implementation of ecodistricts in San Francisco, the city can integrate physical and behavioral sustainability measures from existing ecodistricts such as permeable surfaces, green roofs, stormwater management, …
