Groundcover Community Assembly In High-Diversity Pine Savannas: Seed Arrival And Fire-Generated Environmental Filtering, Kyle E. Harms, Paul R. Gagnon, Heather A. Passmore, Jonathan A. Myers, William J. Platt

Faculty Publications

© 2017 Harms et al. Environmental filtering-abiotic and biotic constraints on the demographic performance of individual organisms-is a widespread mechanism of selection in communities. A given individual is "filtered out" (i.e., selectively removed) when environmental conditions or disturbances like fires preclude its survival and reproduction. Although interactions between these filters and dispersal from the regional species pool are thought to determine much about species composition locally, there have been relatively few studies of dispersal × filtering interactions in species-rich communities and fewer still where fire is also a primary selective agent. We experimentally manipulated dispersal and filtering by fire (pre-fire …

Coordinated Dispersal And Pre-Isthmian Assembly Of The Central American Ichthyofauna, Victor A. Tagliacollo, Scott M. Duke-Sylvester, Wilfredo A. Matamoros, Prosanta Chakrabarty, James S. Albert

Faculty Publications

© The Author(s) 2015. Published by Oxford University Press, on behalf of the Society of Systematic Biologists. We document patterns of coordinated dispersal over evolutionary time frames in heroine cichlids and poeciliine live-bearers, the two most species-rich clades of freshwater fishes in the Caribbean basin. Observed dispersal rate (DO) values were estimated from time-calibrated molecular phylogenies in LAGRANGE+, a modified version of the ML-based parametric biogeographic program LAGRANGE. DO is measured in units of "wallaces" (wa) as the number of biogeographic range-expansion events per million years. DO estimates were generated on a dynamic paleogeographic landscape of five areas over three …

Hemolysis As A Rapid Screening Technique For Assessing The Toxicity Of Native Surfactin And A Genetically Engineered Derivative, William J. Colonna, Mustafa E. Martı, John A. Nyman, Chris Green, Charles E. Glatz

Faculty Publications

If biosurfactants are to achieve their promise in environmental oil-spill remediation, their toxicity to marine life must be assessed. A killifish larvae assay is commonly used as a measure of toxicity but is difficult and nonlinear in response. Red blood cell (RBC) hemolysis has also been the basis for assays of some surfactant levels. Here we present a modified sheep RBC suspension assay and compare its response to that of the fish assay for surfactin and its genetically modified variant fatty-acyl-glutamate (FA-Glu). This is the first report of hemolytic activity as a property of FA-Glu. The method's potential for screening …

The Ecological Adaptability Of Phragmites Australis To Interactive Effects Of Water Level And Salt Stress In The Yellow River Delta, Bo Guan, Junbao Yu, Aixin Hou, Guangxuan Han, Guangmei Wang, Fanzhu Qu, Jiangbao Xia, Xuehong Wang

Faculty Publications

Soil salinity and waterlogging are two major environmental problems in estuarine wetlands. To prevent the typical wetland plants from degradation by soil salinization and salt waterlogging and more effectively use the plants to provide wetland ecosystem services, we examined the ecological adaptability of Phragmites australis, a characteristic plant species in the Yellow River Delta, to the interactive effects of water level and salt stress. The results showed that P. australis adapts to salt and water table stressed environments through slowing down the growth rate, maintaining the tiller number, and adjusting the biomass allocation of different organs. The highest plant height …

Land Use Influencing The Spatial Distribution Of Urban Crime: A Case Study Of Szczecin, Poland, Natalia Sypion-Dutkowska, Michael Leitner

Faculty Publications

This paper falls into a common field of scientific research and its practical applications at the interface of urban geography, environmental criminology, and Geographic Information Systems (GIS). The purpose of this study is to identify types of different land use which influence the spatial distribution of a set of crime types at the intra-urban scale. The originality of the adopted approach lies in its consideration of a large number of different land use types considered as hypothetically influencing the spatial distribution of nine types of common crimes, geocoded at the address-level: car crimes, theft of property-other, residential crimes, property damage, …

First Evidence Of Denitrification Vis-À-Vis Monsoon In The Arabian Sea Since Late Miocene, Shubham Tripathi, Manish Tiwari, Jongmin Lee, Boo Keun Khim

Faculty Publications

© The Author(s) 2017. In the Arabian Sea, South Asian monsoon (SAM)-induced high surface water productivity coupled with poor ventilation of intermediate water results in strong denitrification within the oxygen minimum zone (OMZ). Despite the significance of denitrification in the Arabian Sea, we have no long-term record of its evolution spanning the past several million years. Here, we present the first record of denitrification evolution since Late Miocene (∼10.2 Ma) in the Eastern Arabian Sea, where the SAM generates moderate surface water productivity, based on the samples retrieved during the International Ocean Discovery Program (IODP) Expedition 355. We find that …

Synthetic Aperture Radar (Sar)-Based Paddy Rice Monitoring System: Development And Application In Key Rice Producing Areas In Tropical Asia, T. D. Setiyono, F. Holecz, N. I. Khan, M. Barbieri, E. Quicho, F. Collivignarelli, A. Maunahan, L. Gatti, G. C. Romuga

Faculty Publications

Reliable and regular rice information is essential part of many countries' national accounting process but the existing system may not be sufficient to meet the information demand in the context of food security and policy. Synthetic Aperture Radar (SAR) imagery is highly suitable for detecting lowland paddy rice, especially in tropical region where pervasive cloud cover in the rainy seasons limits the use of optical imagery. This study uses multi-temporal X-band and C-band SAR imagery, automated image processing, rule-based classification and field observations to classify rice in multiple locations across Tropical Asia and assimilate the information into ORYZA Crop Growth …

Predictability Of Helminth Parasite Host Range Using Information On Geography, Host Traits And Parasite Community Structure, Tad Dallas, Andrew W. Park, John M. Drake

Faculty Publications

© Cambridge University Press 2016. Host-parasite associations are complex interactions dependent on aspects of hosts (e.g. traits, phylogeny or coevolutionary history), parasites (e.g. traits and parasite interactions) and geography (e.g. latitude). Predicting the permissive host set or the subset of the host community that a parasite can infect is a central goal of parasite ecology. Here we develop models that accurately predict the permissive host set of 562 helminth parasites in five different parasite taxonomic groups. We developed predictive models using host traits, host taxonomy, geographic covariates, and parasite community composition, finding that models trained on parasite community variables were …

Immigrant Education And Race: Alternative Approaches To “Americanization” In Los Angeles, 1910-1940, Zevi Gutfreund

Faculty Publications

This article explores citizenship’s multiple meanings in Los Angeles by describing five different types of Americanization, or immigrant education, in the city of angels from 1910 to 1940. The federal racialization of access to citizenship influenced these alternative approaches to Americanization at a local level. In the context of Supreme Court rulings and federal laws that made it difficult for immigrants of color to naturalize in the United States during the Progressive Era, Anglo officials in the school district and settlement houses developed an English-only curriculum that benefited only European immigrants. In response to such restrictions,Mexican and Japanese educators in …

Smaller Size-At-Age Menhaden With Coastal Warming And Fishing Intensity, R. Eugene Turner

Faculty Publications

The size-at-age of one million Brevoortia tyrannus and B. patronus, harvested from Maine to Texas over 65 years, were analysed to determine if there was evidence of changes consistent with the well documented temperature size rules. The average annual weight and length for age 3-, 4- and 5-year-old fish declined on both the Atlantic and Gulf of Mexico (GOM) coasts. For example, the average size of a 4-year-old fish captured in 2010 from the Atlantic and GOM, relative to an average 4-year-old fish captured in 1987, is 15 per cent and 11 per cent lighter, respectively. Small changes in the …

Price, Vera Pospelova, Kara Bogus, Gerard J. M. Versteegh, Fabienne Marret, R. Eugene Turner, Nancy N. Rabalais, Kazumi Matsuoka

Faculty Publications

We establish the cyst-theca relationship of the dinoflagellate cyst species Trinovantedinium pallidifulvum Matsuoka 1987 based on germination experiments of specimens isolated from the Gulf of Mexico. We show that the motile stage is a new species, designated as Protoperidinium louisianensis. We also determine its phylogenetic position based on single-cell polymerase chain reaction (PCR) of a single cell germinated from the Gulf of Mexico cysts. To further refine the phylogeny, we determined the large subunit (LSU) sequence through single-cell PCR of the cyst Selenopemphix undulata isolated from Brentwood Bay (Saanich Inlet, BC, Canada). The phylogeny shows that P. louisianensis is closest …

Faculty Publications

More and more ecologists have started to resurvey communities sampled in earlier decades to determine long-term shifts in community composition and infer the likely drivers of the ecological changes observed. However, to assess the relative importance of and interactions among multiple drivers, joint analyses of resurvey data from many regions spanning large environmental gradients are needed. In this article, we illustrate how combining resurvey data from multiple regions can increase the likelihood of driver orthogonality within the design and show that repeatedly surveying across multiple regions provides higher representativeness and comprehensiveness, allowing us to answer more completely a broader range …

A New Species And Introgression In Eastern Asian Hemlocks (Pinaceae: Tsuga), Garth Holman, Peter Del Tredici, Nathan Havill, Nam Sook Lee, Richard Cronn, Kevin Cushman, Sarah Mathews, Linda Raubeson, Christopher S. Campbell

Faculty Publications

© Copyright 2017 by the American Society of Plant Taxonomists. Species delimitation in Pinaceae is often challenged by limited morphological differentiation and introgression. In Tsuga (hemlocks), species delimitation has been most challenging among northeastern Asian taxa, where the species are weakly marked morphologically and range in number from three to five in previous studies. Two low-copy nuclear four-coumarase-ligase (4CL) genes andmorphology strongly support a clade of the Japanese endemic T. diversifolia and T. Sieboldii from Japan and Ulleung island (Ulleungdo) in Korea. This clade is here referred to as the oceanic hemlocks. 4CL strongly supports a sister-group relationship of the …

Phylogeography And Species Delimitation In Convict Cichlids (Cichlidae: Amatitlania): Implications For Taxonomy And Plio-Pleistocene Evolutionary History In Central America, Justin C. Bagley, Wilfredo A. Matamoros, Caleb D. Mcmahan, Michael Tobler, Prosanta Chakrabarty, Jerald B. Johnson

Faculty Publications

© 2016 The Linnean Society of London. We investigate phylogeographic patterns and delimit species boundaries within Amatitlania, a genus of Central American cichlid fishes. Phylogenetic analyses of mitochondrial DNA sequences from 318 individuals spanning the geographical ranges of all three currently recognized Amatitlania species strongly supported one major clade, with a relatively diverged subclade corresponding to A. kanna samples from eastern Costa Rica and Panama. Gene trees and networks revealed marked incongruences between phylogeographic structure and morpho-species taxonomy as a result of species-level polyphyly. Bayes factor comparisons of species delimitation models accounting for incomplete lineage sorting under the multispecies coalescent …

Utilizing This New Medium Of Mass-Communication: The Regional Film Distribution Program At The Cleveland Public Library, 1948-1951., Suzanne Marie Stauffer

Faculty Publications

In 1948, the Carnegie Corporation made grants of $25,000 to the Cleveland Public Library and $15,000 to the Missouri State Library to set up 3-year regional educational film distribution programs in northern Ohio and in Missouri. In Cleveland, films were distributed among a consortium of 10 library systems in the region; twenty library systems participated in Missouri. These successful programs served as models for other library systems, and lasted well into the last quarter of the twentieth century, when films in libraries were replaced with videocassettes and later DVDs. This paper explores the antecedents of the program at the Cleveland …

Libraries Are The Homes Of Books: Whiteness In The Construction Of School Libraries, Suzanne Marie Stauffer

Faculty Publications

The bibliographic instructional work, The Children’s Book on How to Use Books and Libraries, issued seven times between 1937 and 1973, utilized the metaphor of the library as the “home of books.” That “home” was constructed as a private, white, middle- class space in which children, who are invited guests, not residents, were expected to behave according to white, middle-class social norms and cultural values. The children depicted were uniformly white, able-bodied, and middle class as well. American cultural values such as individualism, competition, and pragmatism and utilitarianism were celebrated. This work critically analyzes the whiteness of the presentation, including …
