The Use Of Argumentation In Socio-Scientific Issues: Enhancing Evolutionary Biology Instruction, Heath R. Marchand 2015 The College at Brockport

The Use Of Argumentation In Socio-Scientific Issues: Enhancing Evolutionary Biology Instruction, Heath R. Marchand

Education and Human Development Master's Theses

With the adoption of the Next Generation Science Standards (NGSS), further emphasis in science education is being placed on preparing students to become more informed voters regarding social, ethical, economic and political topics that affect contemporary society. Parallel to this shift is a stronger emphasis on integrating evolutionary theory as a unifying concept in the biological sciences. Given that evolution is one of the aforementioned topics commonly discussed and debated about in social and political arenas, ensuring that instruction provides students from all backgrounds a comprehensive understanding of its principals is becoming increasingly important in contemporary science education.

Coral Growth Under Thermal Stress And Different Levels Of Light Intensity In Acropora Aspera., Devan Y. Klein, Mary W. Barana, Leeanne A. Obilor 2015 Dominican University of California

Coral Growth Under Thermal Stress And Different Levels Of Light Intensity In Acropora Aspera., Devan Y. Klein, Mary W. Barana, Leeanne A. Obilor

Scholarly and Creative Works Conference

In this study we examined the growth rates of coral species Acropora aspera in conditions of high thermal stress which are expected to become more common because of climate change. During higher than normal temperature periods, corals can experience bleaching which is the loss of algal symbionts from their tissue. Since corals depend on these photosynthetic organisms for most of their nutrition, this loss can lead to mass mortality. However, if the period of thermal stress happens during cloudy weather, bleaching events are less severe, and thus it is possible that shading reefs could help mitigate the effects of warmer ...


Analysis Of The Diets Of The Northern Spotted Owl And Barred Owl, Valeria Briones 2015 Dominican University of California

Analysis Of The Diets Of The Northern Spotted Owl And Barred Owl, Valeria Briones

Scholarly and Creative Works Conference

The Northern Spotted Owl, a once thriving species is now a threatened species and on the verge of endangerment. The Barred Owl, a species native to the eastern United States over the past few centuries has expanded its range into that of the Northern Spotted Owl, causing a major threat to the Northern Spotted Owl Populations. This paper is a synthesis of the existing literature of the diets of the Northern Spotted Owl and Barred Owl individually as well as in areas in which they occur sympatrically. With this summary of literature, the reader can gain an understanding of the ...


Elevational Gradients In Β-Diversity Reflect Variation In The Strength Of Local Community Assembly Mechanisms Across Spatial Scales, J Sebastián Tello, Jonathan A. Myers, Manuel J. Macia, Alfredo F. Fuentes, Leslie Cayola, Gabriel Arellano, M Isabel Loza, Vania Torrez, Maritza Cornejo, Tatiana B. Miranda, Peter M. Jørgensen 2015 Washington University in St. Louis

Elevational Gradients In Β-Diversity Reflect Variation In The Strength Of Local Community Assembly Mechanisms Across Spatial Scales, J Sebastián Tello, Jonathan A. Myers, Manuel J. Macia, Alfredo F. Fuentes, Leslie Cayola, Gabriel Arellano, M Isabel Loza, Vania Torrez, Maritza Cornejo, Tatiana B. Miranda, Peter M. Jørgensen

Biology Faculty Publications

Despite long-standing interest in elevational-diversity gradients, little is known about the processes that cause changes in the compositional variation of communities (β-diversity) across elevations. Recent studies have suggested that β-diversity gradients are driven by variation in species pools, rather than by variation in the strength of local community assembly mechanisms such as dispersal limitation, environmental filtering, or local biotic interactions. However, tests of this hypothesis have been limited to very small spatial scales that limit inferences about how the relative importance of assembly mechanisms may change across spatial scales. Here, we test the hypothesis that scale-dependent community assembly mechanisms shape ...


An Individual-Based Model Of Chaparral Vegetation Response To Frequent Wildfire, Timothy Lucas, Dayna Mann, Reanna Dona 2015 Pepperdine University

An Individual-Based Model Of Chaparral Vegetation Response To Frequent Wildfire, Timothy Lucas, Dayna Mann, Reanna Dona

Undergraduate Research And Scholarly Achievement Symposium

In recent years, the Santa Monica Mountains (SMM) have been plagued by frequent wildfires which threaten the native chaparral species. Nonsprouting chaparral species are completely killed by a fire, but their seeds germinate in response to fire cues. Facultative sprouters both resprout after a wildfire and release seeds that germinate post-fire. This project is based on data collected since 1986 at a biological preserve adjacent to the Malibu campus of Pepperdine University with an average fire return interval of 7.5 years. We present a spatial model that simulates the growth, seed dispersal and resprouting behavior of individual shrubs that ...


From The Field To The Lab: Best Practices For Field Preservation Of Bat Specimens For Molecular Analyses, Angelique Corthals, Alynn Martin, Omar M. Warsi, Megan Woller-Skar, Winston Lancaster, Amy L. Russell, Liliana M. Dávalos 2015 John Jay College of Criminal Justice

From The Field To The Lab: Best Practices For Field Preservation Of Bat Specimens For Molecular Analyses, Angelique Corthals, Alynn Martin, Omar M. Warsi, Megan Woller-Skar, Winston Lancaster, Amy L. Russell, Liliana M. Dávalos

Amy L. Russell

Studies in molecular ecology depend on field-collected samples for genetic information, and the tissue sampled and preservation conditions strongly affect the quality of the DNA obtained. DNA yields from different tissue types have seldom been compared, even though these media may influence DNA degradation under field conditions. We analyzed DNA yield from buccal swabs and wing punches harvested from live bats using nucleic acid quantification as well as quantitative PCR for a single-copy nuclear locus. We also compared DNA yields from wing tissue preserved in three media: ethanol, NaCl-saturated dimethyl sulfoxide (DMSO), and silica desiccant. Wing punches yielded more total ...


Relatedness, Conflict, And The Evolution Of Eusociality, Xiaoyun Liao, Stephen Rong, David C. Queller 2015 Washington University in St Louis

Relatedness, Conflict, And The Evolution Of Eusociality, Xiaoyun Liao, Stephen Rong, David C. Queller

Biology Faculty Publications

The evolution of sterile worker castes in eusocial insects was a major problem in evolutionary theory until Hamilton developed a method called inclusive fitness. He used it to show that sterile castes could evolve via kin selection, in which a gene for altruistic sterility is favored when the altruism sufficiently benefits relatives carrying the gene. Inclusive fitness theory is well supported empirically and has been applied to many other areas, but a recent paper argued that the general method of inclusive fitness was wrong and advocated an alternative population genetic method. The claim of these authors was bolstered by a ...


The Influence Of Spines And Size Refuge On Predation Of Devonian Brachiopods From The Lime Creek Formation Near Rockford, Iowa, Broc S. Kokesh 2015 University or Minnesota, Morris

The Influence Of Spines And Size Refuge On Predation Of Devonian Brachiopods From The Lime Creek Formation Near Rockford, Iowa, Broc S. Kokesh

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Brachiopods are small invertebrates that live on the seafloor and are prominent in the fossil record from 540 to 250 million years ago. An interesting feature of some species is that large spines develop on their exterior surfaces. These spines are thought to have evolved for defense against predators, but fossils are limited in how much information they contain about how organisms interact with each other. In this study, I examined wound markings on fossils of both a spiny (Atrypa rockfordensis) and spineless (Atrypa devoniana) species of brachiopod. Results show that spiny brachiopods were less frequently injured, suggesting that spines ...

Ship-Induced Solitary Riemann Waves Of Depression In Venice Lagoon, Kevin E. Parnall, Tarmo Soomere, Luca Zaggia, Artem Rodin, Giuliano Lorenzetti, John Rapaglia, Gian Marco Scarpaf 2015 James Cook University

Ship-Induced Solitary Riemann Waves Of Depression In Venice Lagoon, Kevin E. Parnall, Tarmo Soomere, Luca Zaggia, Artem Rodin, Giuliano Lorenzetti, John Rapaglia, Gian Marco Scarpaf

Biology Faculty Publications

We demonstrate that ships of moderate size, sailing at low depth Froude numbers (0.37–0.5) in a navigation channel surrounded by shallow banks, produce depressions with depths up to 2.5 m. These depressions (Bernoulli wakes) propagate as long-living strongly nonlinear solitary Riemann waves of depression substantial distances into Venice Lagoon. They gradually become strongly asymmetric with the rear of the depression becoming extremely steep, similar to a bore. As they are dynamically similar, air pressure fluctuations moving over variable-depth coastal areas could generate meteorological tsunamis with a leading depression wave followed by a devastating bore-like feature.


Terrestrial Lidar-Based Automated Counting Of Swiftlet Nests In The Caves Of Gomantong, Sabah, Borneo., Donald A. McFarlane, Warren Roberts, Manfred Buchroithner, Guy Van Rentergem, Joyce Lundberg, Stefan Hautz 2015 Scripps College, The Claremont Colleges, California, USA

Terrestrial Lidar-Based Automated Counting Of Swiftlet Nests In The Caves Of Gomantong, Sabah, Borneo., Donald A. Mcfarlane, Warren Roberts, Manfred Buchroithner, Guy Van Rentergem, Joyce Lundberg, Stefan Hautz

International Journal of Speleology

High resolution terrestrial laser scanning (TLS) within the Simud Hitam cave, Gomantong, has proven successful at discriminating the nests of black-nest swiftlets from roosting bats in high, inaccessible locations. TLS data was imported into ArcGIS software, allowing for semi-automated counting of nests. Spatial analysis of nest locations has established a maximum packing density of 268 nests/m2 in optimum locations, which correspond to roof slopes of >20 degrees. Rhinolophid bats roost adjacent to, but not within nest locations, preferring roof surfaces close to horizontal.


Building Resilience Into Quaking Aspen Management, Paul C. Rogers 2015 Utah State University

Building Resilience Into Quaking Aspen Management, Paul C. Rogers

Aspen Bibliography

Throughout the 20th century, forest scientists and land managers were guided by principles of succession with regard to aspen forests. The historical model depicted aspen as a "pioneer species" that colonizes a site following disturbance and is eventually overtopped by conifers. Aspen systems are more diverse, however, than previously described. Not only are there distinctive seral and stable aspen, but variations within these types require appropriate management considerations (Rogers et al. 2014). We recommend a strategic approach to aspen resilience that builds upon traditional aspen ecology and incorporates knowledge of varying aspen functional types, effective monitoring, historical disturbance ecology ...


Managing Ungulate Browsing For Sustainable Aspen, Samuel B. St. Clair, Paul C. Rogers, Michael R. Kuhns 2015 Brigham Young University - Provo

Managing Ungulate Browsing For Sustainable Aspen, Samuel B. St. Clair, Paul C. Rogers, Michael R. Kuhns

Aspen Bibliography

In montane forests of the Intermountain West composition and function are often defined by what happens with quaking aspen. Aspen is a pioneer species that regenerates quickly following disturbance and then establishes ecological conditions under which the rest of the biological community develops. Quaking aspen forests have high biodiversity and provide ideal habitat for many animals. Aspen regeneration from root sprouts is highly palatable to wildlife and livestock. When browsing becomes chronic it leads to regeneration failure and eventual loss of aspen forests and associated species. Ironically, this can result in habitat and forage loss for wildlife and livestock. Here ...


Cuban Treefrogs, Osteopilus Septentrionalis (Duméril & Bibron 1841) (Anura: Hylidae), And Other Nonindigenous Herpetofauna Interdicted In Grenada, Lesser Antilles., Louis A. Somma, Paul R. Graham 2015 Florida State Collection of Arthropods

Cuban Treefrogs, Osteopilus Septentrionalis (Duméril & Bibron 1841) (Anura: Hylidae), And Other Nonindigenous Herpetofauna Interdicted In Grenada, Lesser Antilles., Louis A. Somma, Paul R. Graham

Papers in Herpetology

The number of introduced nonindigenous species of amphibians and reptiles within the greater Caribbean, including Grenada, is escalating and has become an ever-increasing critical conservation concern (Daudin and de Silva 2011; Powell et al. 2011; Powell and Henderson 2012). The amount of development, tourism, and consequent import commerce is increasing, requiring careful regulation of the pet trade and fauna introduced for biological control as well as diligence in cargo inspection. Herein we document the first records of nonindigenous Cuban Treefrogs, Osteopilus septentrionalis (Duméril and Bibron 1841), interdicted from cargo, along with recent interceptions of two species of nonindigenous lizards already ...


The Effects Of Tetracycline And Ibuprofen On Common Duckweed, Lemna Minor, John Von Drasek 2015 College of DuPage

The Effects Of Tetracycline And Ibuprofen On Common Duckweed, Lemna Minor, John Von Drasek

Honors Council of Illinois Region 2015 Student Research Symposium

Pharmaceuticals and chemicals are finding their way into drinking water by means of household and industrial sewage. This study explores the effects of two common pharmaceuticals—tetracycline and ibuprofen—on the growth of Common Duckweed, Lemna minor. The number of duckweed per test tube for each treatment was compared after 37 days. Tetracycline was not found to effect clonal growth of duckweed. There was significant difference in duckweed count between the ibuprofen treatment and the control treatment with ibuprofen inhibiting the growth of the duckweed. It is possible that the tetracycline prevented the protein synthesis of any harmful bacteria growing ...


Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard 2015 University of Nebraska-Lincoln

Global Warming And Population Responses Among Great Plains Birds, Paul A. Johnsgard

Zea E-Books

Based on an analysis of 47 years (1967–2014) of Audubon Christmas Bird Counts (CBC), evidence for population changes and shifts in early winter (late December) ranges of nearly 150 species of birds in the Great Plains states is summarized, a region defined as including the Dakotas, Nebraska, Kansas, Oklahoma, and the Texas panhandle. The rationale for this study had its origins in Terry Root’s 1988 Atlas of North American Wintering Birds. Root’s landmark study provided a baseline for evaluating the nationwide winter distributions of 253 North American birds in the mid-20th century, using data from the National ...

Predicting Invasion Rates For Phragmites Australis, Rachel Nydegger, Jacob Duncan, James A. Powell

Browse All Undergraduate research

In wetlands of Utah and southern Idaho as well as estuaries of the east coast, the ten-foot tall invasive grass Phragmites australis can be found near waterways, where it outcompetes native plants and degrades wildlife habitat. Phragmites australis is an obligate out-crossing plant that can spread sexually through seed disper- sal, or asexually via stolons and rhi- zomes (Kettenring and Mock 2012). Small patches are usually a single genetic individual, spreading vegetatively (and slowly) via runners; when patches become genetically diverse viable seeds are produced and invasion rates can be increase by an order of magnitude (Kettenring et al. 2011)

Contrasting Effects Of Different Mammalian Herbivores On Sagebrush Plant Communities, Kari E. Veblen, Kyle C. Nehring, Chris M. McGlone, Mark E. Ritchie 2015 Utah State University

Contrasting Effects Of Different Mammalian Herbivores On Sagebrush Plant Communities, Kari E. Veblen, Kyle C. Nehring, Chris M. Mcglone, Mark E. Ritchie

Kari E. Veblen

Herbivory by both grazing and browsing ungulates shapes the structure and functioning of terrestrial ecosystems worldwide, and both types of herbivory have been implicated in major ecosystem state changes. Despite the ecological consequences of differences in diets and feeding habits among herbivores, studies that experimentally distinguish effects of grazing from spatially co-occurring, but temporally segregated browsing are extremely rare. Here we use a set of long-term exclosures in northern Utah, USA, to determine how domestic grazers vs. wild ungulate herbivores (including browsers and mixed feeders) affect sagebrush-dominated plant communities that historically covered ~62 million ha in North America. We sampled ...
