Winter Field Report, December 2017 To February 2018, W. Ross Silcock

Nebraska Bird Review

This was not a spectacular fall by most measures, but, as usual, there was much to chew on. Continuing the trend seen in recent falls, lingering has become the norm; this phenomenon is across the board, involving, for example, Baird’s Sandpiper, Greater Yellowlegs, Mourning Dove, American White Pelican, Barn Owl, Lesser Goldfinch, several native sparrow species, Palm and Orange-crowned Warblers, and even rearof- the-order Dickcissel. Apparent range expansion is occurring with Red-shouldered Hawk and Barred Owl, the former northward and the latter westward. A couple of taxonomic notes relate to the subspecies Buteo jamaicensis abieticola of Red-tailed Hawk and subspecies …


First Stewards: Ecological Outcomes Of Forest And Wildlife Stewardship By Indigenous Peoples Of Wisconsin, Usa, Donald M. Waller, Nicholas J. Reo Mar 2018

First Stewards: Ecological Outcomes Of Forest And Wildlife Stewardship By Indigenous Peoples Of Wisconsin, Usa, Donald M. Waller, Nicholas J. Reo

Dartmouth Scholarship

Indigenous peoples manage forestlands and wildlife differently than public and private forestland managers. To evaluate ecological outcomes from these differences, we compared the structure, composition, and diversity of Ojibwe and Menominee tribal forests to nearby nontribal forestlands in northern Wisconsin. These indigenous peoples seek to manage forests for mature conditions, accommodate wolves and other predators, and hunt deer to sustain traditional livelihood values. Their forests are often more mature with higher tree volume, higher rates of tree regeneration, more plant diversity, and fewer invasive species than nearby nontribal forestlands. In contrast, nontribal forestlands lost appreciable plant diversity in the 20th …


The Tensile Root Strength Of Emergent Coastal Macrophytes, Lauris Olivia Hollis Mar 2018

The Tensile Root Strength Of Emergent Coastal Macrophytes, Lauris Olivia Hollis

LSU Doctoral Dissertations

Spartina patens is a dominant emergent macrophyte in fresh, intermediate, and brackish marshes along the Atlantic and Gulf coasts of United States where its biomechanical properties are a key component of wetland health and resilience. Its root biomass and tensile root strength are essential for anchorage, erosion protection, and are important determinants of soil strength. Nutrients and the herbicide atrazine are suspected of negatively impacting this wetland plant and others. The objectives of this study were to: 1) ascertain the tensile root strength of five emergent coastal macrophytes in coastal estuaries, and 2) test the effects of nutrient addition, atrazine …


Food Habits Of Imperiled Plains Topminnow And Diet Overlap With Invasive Western Mosquitofish In The Central Great Plains, Joseph Thiessen, Keith D. Koupal, Casey W. Schoenebeck, Julie J. Shaffer Mar 2018

Food Habits Of Imperiled Plains Topminnow And Diet Overlap With Invasive Western Mosquitofish In The Central Great Plains, Joseph Thiessen, Keith D. Koupal, Casey W. Schoenebeck, Julie J. Shaffer

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Plains Topminnow (Fundulus sciadicus) populations have experienced large declines throughout the Central Great Plains, with Western Mosquitofish (Gambusia affinis) introductions suggested as a contributing factor. There are limited studies identifying the food habits of Plains Topminnow and the trophic interactions with Western Mosquitofish. This study sought to determine if a diet overlap exists between the Plains Topminnow and the introduced Western Mosquitofish by identifying the feeding habits of both species. We analyzed diets from lentic and lotic populations of Plains Topminnow captured in August and found lentic topminnows employed a generalist diet while lotic topminnow selected for gastropods. …


Redescription And Phylogenetic Analysis Of The Materials Assigned To The Taxon "Captorhinikos" Chozaensis, Jason Paul Jung Mar 2018

Redescription And Phylogenetic Analysis Of The Materials Assigned To The Taxon "Captorhinikos" Chozaensis, Jason Paul Jung

Electronic Theses, Projects, and Dissertations

“Captorhinikos” chozaensis is a multiple-tooth-rowed captorhinid reptile from the Lower Permian Clear Fork Group, undivided formation. Upon re-examination of the materials associated with the species from both the Chicago Field Museum of Natural History, and the Smithsonian United States National Museum, I reaffirm their affinity and collective identity as a valid taxon. “Captorhinikos” chozaensis does not, however, belong with either of the two members of its genus, C. valensis or “C.” parvus, instead occupying its own branch on the phylogenetic tree of the Captorhinidae. This conclusion is based in strong results from a combined phylogenetic parsimony analysis combined with …


Burned Area Mapping Of An Escaped Fire Into Tropical Dry Forest In Western Madagascar Using Multi-Season Landsat Oli Data, Anne C. Axel Mar 2018

Burned Area Mapping Of An Escaped Fire Into Tropical Dry Forest In Western Madagascar Using Multi-Season Landsat Oli Data, Anne C. Axel

Biological Sciences Faculty Research

A human-induced fire cleared a large area of tropical dry forest near the Ankoatsifaka Research Station at Kirindy Mitea National Park in western Madagascar over several weeks in 2013. Fire is a major factor in the disturbance and loss of global tropical dry forests, yet remotely sensed mapping studies of fire-impacted tropical dry forests lag behind fire research of other forest types. Methods used to map burns in temperature forests may not perform as well in tropical dry forests where it can be difficult to distinguish between multiple-age burn scars and between bare soil and burns. In this study, the …


2017-2018 Christmas Bird Counts, Don Paseka Mar 2018

2017-2018 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Sixteen counts were held during the 2017-18 Christmas Bird Count season, which is one more than has ever been done in the past. Although the Crawford count was not done this season, the new Lower Platte River count, centered at the junction of Platteview Road and 204th St. south of Gretna, was added. A total 236 observers took part in at least one count, 26 did two counts, four did three counts, five did four counts and four persons did six counts. However, special recognition goes to Gary Roberts, who did eight counts this season. I am not aware of …

Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo Feb 2018

Haemosporidian Parasites And Host Immune Function Of Galapagos Avifauna, Maricruz Jaramillo

Dissertations

The large number of emergent infectious diseases witnessed in the past few decades has increased interest in the ecology and distribution of potentially threatening pathogens worldwide. Island species are often considered more vulnerable to parasites due to their impoverished parasite communities, long isolation from disease and low genetic diversity. Avian surveys done by our group on the Galapagos Islands have found various pathogens infecting their endemic avifauna, including haemosporidian parasites of the genera Plasmodium and Haemoproteus. My research seeks to understand the relationships between two haemosporidian parasites (blood parasites) and their multiple bird hosts in Galapagos and to explore …


Learning To See The Forest For The Corn: Establishing Sense Of Place And Community In A Field-Based Ecology Course For Pre-Service Educators, Michelle Edgcomb Friday Feb 2018

Learning To See The Forest For The Corn: Establishing Sense Of Place And Community In A Field-Based Ecology Course For Pre-Service Educators, Michelle Edgcomb Friday

Theses and Dissertations

In this dissertation grounded theory techniques were used to characterize pre-service educators’ experiences in a semester-long, field-based ecology course. Through participation in a citizen science project, participants formed a community of practice that extended their conceptions of themselves as ecology students and scientists. Extended field experiences in a variety of local ecosystems contributed to the development of a sense of place. Paired fieldwork with lecture aided their developing ecological literacy and their understanding of place-based pedagogy. All of these combined to support their growing understanding of their role in field-based ecology education. Lack of background in ecology and ecology pedagogy …

Hydraulic Fracturing Fluid Biocide, Tributyl Tetradecyl Phosphonium Chloride, Causes Mitochondrial Dysfunction That Is Enhanced By Sodium Chloride In Chironomus Riparius, Zainab Hussain Alali

Seton Hall University Dissertations and Theses (ETDs)

Tributyl tetradecyl phosphonium chloride (TTPC) is a biocide utilized in the hydraulic fracturing process to extract oil and natural gas from deep underground. This study used 4th instar Chironomus riparius to investigate the toxicity of TTPC, NaCl, and TTPC+NaCl. Our results show that the 24 h LC50s for TTPC, NaCl, and TTPC+NaCl were 0.57 mg/L, >10,000 mg/L, and 0.32 mg/L, respectively, while the 48 h LC50s for the same treatments were 0.48 mg/L, 9808 mg/L, and 0.22 mg/L, respectively. Additionally, TTPC’s mechanism of action was investigated by measuring the levels of adenosine triphosphate (ATP), superoxide …

The Wasteland, Tiasa Adhya Feb 2018

The Wasteland, Tiasa Adhya

The Goose

Riverine floodplains and deltas that have cradled human civilization and are now ravaged by ecologically blind land-use policies form the context of this poem. Policies that term nutrient rich wetlands as "wastelands" are economically motivated and backed by policy makers for short-term gains. The conversion of wetlands makes refugees out of resident wild species. The first few lines of the poem describe the character of the fishing cat, the only cat in South Asia that is adapted for wetlands and is an indicator of the health of wetland ecosystems. The poem talks of a nemesis that awaits the human world—we …

Overdispersed Spatial Patterning Of Dominant Bunchgrasses In Southeastern Pine Savannas, Katherines A. Hovanes, Kyle E. Harms, Paul R. Gagnon, Jonathan A. Myers, Bret D. Elderd Feb 2018

Overdispersed Spatial Patterning Of Dominant Bunchgrasses In Southeastern Pine Savannas, Katherines A. Hovanes, Kyle E. Harms, Paul R. Gagnon, Jonathan A. Myers, Bret D. Elderd

Biology Faculty Research

Spatial patterning is a key natural history attribute of sessile organisms that frequently emerges from and dictates potential for interactions among organisms. We tested whether bunchgrasses, the dominant plant functional group in longleaf pine savanna groundcover communities, are nonrandomly patterned by characterizing the spatial dispersion of three bunchgrass species across six sites in Louisiana and Florida. We mapped bunchgrass tussocks of >5.0 cm basal diameter in three [Formula: see text] plots at each site. We modeled tussocks as two-dimensional objects to analyze their spatial relationships while preserving sizes and shapes of individual tussocks. Tussocks were overdispersed (more regularly spaced than …

Avolio, Neil Bettez, Rinku Roy Chowdhury, Lindsay E. Darling, Peter M. Groffman, J. Morgan Grove, Sharon J. Hall, James B. Heffernan, Jennifer Learned, Christopher Neill, Kristen C. Nelson, Diane E. Pataki, Benjamin L. Ruddell, Meredith K. Steele, Tara L. E. Trammell

Ecology Center Publications

Urban ecosystems are widely hypothesized to be more ecologically homogeneous than natural ecosystems. We argue that urban plant communities assemble from a complex mix of horticultural and regional species pools, and evaluate the homogenization hypothesis by comparing cultivated and spontaneously occurring urban vegetation to natural area vegetation across seven major U.S. cities. There was limited support for homogenization of urban diversity, as the cultivated and spontaneous yard flora had greater numbers of species than natural areas, and cultivated phylogenetic diversity was also greater. However, urban yards showed evidence of homogenization of composition and structure. Yards were compositionally more …


Global Macroevolution And Macroecology Of Passerine Song, William D. Pearse, Ignacio Morales-Castilla, Logan S. James, Maxwell Farrell, Frédéric Boivin, T. Jonathan Davies Feb 2018

Global Macroevolution And Macroecology Of Passerine Song, William D. Pearse, Ignacio Morales-Castilla, Logan S. James, Maxwell Farrell, Frédéric Boivin, T. Jonathan Davies

Ecology Center Publications

Studying the macroevolution of the songs of Passeriformes (perching birds) has proved challenging. The complexity of the task stems not just from the macroevolutionary and macroecological challenge of modeling so many species, but also from the difficulty in collecting and quantifying birdsong itself. Using machine learning techniques, we extracted songs from a large citizen science dataset, and then analyzed the evolution, and biotic and abiotic predictors of variation in birdsong across 578 passerine species. Contrary to expectations, we found few links between life‐history traits (monogamy and sexual dimorphism) and the evolution of song pitch (peak frequency) or song complexity (standard …


Scorpions Of The Horn Of Africa (Arachnida, Scorpiones). Part Xiv. Hottentotta Somalicus Sp. N. (Buthidae) From Somalia, František Kovařík Feb 2018

Scorpions Of The Horn Of Africa (Arachnida, Scorpiones). Part Xiv. Hottentotta Somalicus Sp. N. (Buthidae) From Somalia, František Kovařík

Euscorpius

Hottentotta somalicus sp. n. from Somalia is described and fully complemented with color photos. Morphologically it is similar to H. polystictus (Pocock, 1896). These two species have very narrow metasomal segments (1.63–1.73 in both sexes versus 1.31–1.61 in both sexes of other Hottentotta species from the Horn of Africa). H. polystictus and H. somalicus sp. n. occur in separate areas (Somaliland versus Somalia) and can be differentiated by color.


Advancing Behavioural Genomics By Considering Timescale, Clare C. Rittschof, Kimberly A. Hughes Feb 2018

Advancing Behavioural Genomics By Considering Timescale, Clare C. Rittschof, Kimberly A. Hughes

Entomology Faculty Publications

Animal behavioural traits often covary with gene expression, pointing towards a genomic constraint on organismal responses to environmental cues. This pattern highlights a gap in our understanding of the time course of environmentally responsive gene expression, and moreover, how these dynamics are regulated. Advances in behavioural genomics explore how gene expression dynamics are correlated with behavioural traits that range from stable to highly labile. We consider the idea that certain genomic regulatory mechanisms may predict the timescale of an environmental effect on behaviour. This temporally minded approach could inform both organismal and evolutionary questions ranging from the remediation of early …


Authors And Editors Assort On Gender And Geography In High-Rank Ecological Publications, Kezia R. Manlove, Rebecca M. Belou Feb 2018

Authors And Editors Assort On Gender And Geography In High-Rank Ecological Publications, Kezia R. Manlove, Rebecca M. Belou

Wildland Resources Faculty Publications

Peer-reviewed publication volume and caliber are widely-recognized proxies for academic merit, and a strong publication record is essential for academic success and advancement. However, recent work suggests that publication productivity for particular author groups may also be determined in part by implicit biases lurking in the publication pipeline. Here, we explore patterns of gender, geography, and institutional rank among authors, editorial board members, and handling editors in high-impact ecological publications during 2015 and 2016. A higher proportion of lead authors had female first names (33.9%) than editorial board members (28.9%), and the proportion of female first names among handling editors …

Stabilization Of Lead (Pb) And Zinc (Zn) In Contaminated Rice Paddy Soil Using Starfish: A Preliminary Study, Deok Hyun Moon, Inseong Hwang, Agamemnon Koutsospyros, Kyung Hoon Cheong, Yong Sik Ok, Won Hyun Ji, Jeong Hun Park

Civil Engineering Faculty Publications

Lead (Pb) and zinc (Zn) contaminated rice paddy soil was stabilized using natural (NSF) and calcined starfish (CSF). Contaminated soil was treated with NSF in the range of 0-10 wt.% and CSF in the range of 0-5 wt.% and cured for 28 days. Toxicity characteristic leaching procedure (TCLP) test was used to evaluate effectiveness of starfish treatment. Scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX) analyses were conducted to investigate the mechanism responsible for effective immobilization of Pb and Zn. Experimental results suggest that NSF and CSF treatments effectively immobilize Pb and Zn in treated rice paddy soil. TCLP levels for …
