Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia 2015 University of Turin, Torino

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia

International Journal of Speleology

Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models (GLMMs) to ...


In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark 2015 Southern Illinois University Edwardsville

In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated ...


Distributional Expansion Of The Hispid Cotton Rat (Sigmodon Hispidus) Into Dawson County, Nebraska, Jennifer D. Frisch, Keith Geluso, Joseph T. Springer 2015 University of Nebraska at Kearney

Distributional Expansion Of The Hispid Cotton Rat (Sigmodon Hispidus) Into Dawson County, Nebraska, Jennifer D. Frisch, Keith Geluso, Joseph T. Springer

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

In the last century, the Hispid Cotton Rat (Sigmodon hispidus) has moved northward in central parts of the United States, reaching Nebraska in the late 1950s. Recent surveys demonstrate Hispid Cotton Rats inhabit counties across southern parts of Nebraska south of the Platte River. Herein, we report on captures of S. hispidus from a new county (Dawson County), its seasonal occurrence at our study site, and the first known record of the Hispid Cotton Rat north of channels of the Platte River. Our captures represent one of the northern-most records in Nebraska.

Choosing content for this discovery portal is comparable to past scholarly practice of creating and publishing subject bibliographies, except metadata and data are ...


Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell 2015 Otterbein University

Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell

Distinction Papers

Same sex pair bonding can be found throughout various animal species. These relationships can be common in monogamous species, especially when there is a lack of members of the opposite sex. Budgerigars, Melopsittacus undulatus, are a socially monogamous species, which create strong pair bonds but are also known to engage in extra pair copulations. When looking at an all-male flock of budgerigars, the question arises, are these bonds easily broken or disrupted by a third party individual. After determining seven pair bonds in a flock of 32 males, these pairs were removed from an aviary and placed in separate lab ...


Who Invented The Mule Deer (Odocoileus Hemionus)? On The Authorship Of The Fraudulent 1812 Journal Of Charles Le Raye, Neal Woodman 2015 USGS

Who Invented The Mule Deer (Odocoileus Hemionus)? On The Authorship Of The Fraudulent 1812 Journal Of Charles Le Raye, Neal Woodman

Neal Woodman

The captivity journal of Charles Le Raye was first published in 1812 as a chapter in A topographical description of the state of Ohio, Indiana Territory, and Louisiana, a volume authored anonymously by “a late officer in the U. S. Army”. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had travelled across broad portions of the Missouri and Yellowstone river drainages a few years before the Lewis and Clark expedition (1804–1806), and his account of the land, its people, and its natural resources was relied upon as a primary ...


New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman 2015 Northeastern State University, OK

New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman

Neal Woodman

Despite having a broad geographic distribution, Merriam’s Shrew (Sorex merriami Dobson 1890) is known from a relatively few, widely-scattered localities. In North Dakota, the species was known from only a single poorly-preserved specimen collected in 1913 near Medora. We recently collected two new specimens of Merriam’s Shrew from Billings and McKenzie counties in the western quarter of the state. These specimens confirm the presence of S. merriami in North Dakota and better define the northeastern edge of the species’ distribution.


Fish Out Of Salt Water: Smoltification In Subyearling Chinook Salmon From The Laurentian Great Lakes, Steve Sharron 2015 The University of Western Ontario

Fish Out Of Salt Water: Smoltification In Subyearling Chinook Salmon From The Laurentian Great Lakes, Steve Sharron

University of Western Ontario - Electronic Thesis and Dissertation Repository

The timing of smoltification in juvenile anadromous salmonids is important to ensure individuals match their preparedness with their migration timing and the optimal conditions in the environment. I performed the first study of smoltification in adfluvial juvenile Chinook salmon naturalized in the Laurentian Great Lakes. In a hatchery study, I found that juveniles from one of these populations have similar patterns of smoltification timing to individuals from anadromous populations. Their Na+/K+ ATPase activity, a common indicator or smolt status, peaked at 7.7 μmoles ADP/mg protein/hour on July 1 in freshwater. During the peak period, individual body ...

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson 2015 Colby College

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of ...


Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath 2015 Boise State University

Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath

Robert Miller

Climate change is having a dramatic effect on many migratory species. Changes in climate may lead to changes in food availability or other proximate cues that affect migratory behavior. We used 13 years (2000–2012) of data on songbird banding and raptor migration counts and captures during autumn migration in the intermountain West to evaluate whether regional temperature or precipitation or hemispheric climate indices predicted autumn migratory timing and energetic condition. We examined overall trends and evaluated the effects of diet and migratory distance on phenology and conditional responses. For the 13-year study period, no temperature, precipitation, or climate index ...


Sociality Increases Juvenile Survival After A Catastrophic Event In The Feral Horse (Equus Caballus), Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein 2015 Princeton University

Sociality Increases Juvenile Survival After A Catastrophic Event In The Feral Horse (Equus Caballus), Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein

Cassandra M.V. Nuñez

In several social species, adult associations have been linked to individual fitness. Less is known about offspring associations and the mechanisms by which they may influence fitness. We investigate the effects of sociality on juvenile survival in feral horses (Equus caballus). We use foal degree (number of associates) and foal weight (number of interactions) to assess sociality’s importance to foal survival of a catastrophic event, the gathering and removal of 40% of the horse population. We found that 1) foal degree was a better predictor of foal survival than was foal weight; 2) following the gather, foals with access ...


Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile 2015 USGS

Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile

Neal Woodman

Substrate use and locomotory behavior of mammals are typically reflected in external characteristics of the forefeet, such as the relative proportions of the digits and claws. Although skeletal anatomy of the forefeet can be more informative than external characters, skeletons remain rare in systematic collections. This is particularly true for the Myosoricinae (Eulipotyphla: Soricidae), a small clade of African shrews that includes both ambulatory forest shrews (Myosorex) and semifossorial mole shrews (Surdisorex). Most species in this subfamily have restricted distributions, and their behavior and ecology are mostly unstudied. To better understand the potential range of locomotory behavior among myosoricines, we ...

Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves 2015 University of New Hampshire - Main Campus

Effects Of Age, Density, And Seasonality On Molt Pattern In The Mammal Genus (Peromyscus), Rebecca Catherine Graves

Honors Theses

Molting, or replacement of pelage (hair) in mammals, occurs during ontogeny as individuals transition from juveniles to adults. Environmental factors can cause variation in molt in many species for thermoregulatory and camouflage purposes. Within and among years molt can vary by time and age or by reproductive status. Past studies have found differences in molt pattern and timing depending upon age, and between captive reared and wild caught individuals. There has been little investigation into the molting characteristics of Peromyscus leucopus and P. maniculatus, specifically in comparison to adults and juveniles. I used molt observed from museum specimens collected at ...


Determinants Of Termite Species Taxonomic, Phylogenetic, And Functional Diversity In The Amazonian Forest, Cristian de Sales Dambros 2015 University of Vermont

Determinants Of Termite Species Taxonomic, Phylogenetic, And Functional Diversity In The Amazonian Forest, Cristian De Sales Dambros

Graduate College Dissertations and Theses

The distribution of species in space is determined by the species dispersal capacity, adaptation to environmental conditions, and response to predators and competitors. To determine the importance of dispersal limitation, environmental filtering, and species interactions on the distribution of species in the Brazilian Amazonian forest, I sampled termites in a large area of Brazil. I investigated patterns in species occurrence that could indicate competition and predation structuring termite communities, and analyzed the association of termite abundance and species richness with the density of ant predators. The spatial distribution of termites, and their association with climatic and edaphic conditions were also ...


Rafinesque’S Names For Western American Mammals, Including The Earliest Scientific Name For The Coyote (Canis Latrans Say, 1822), Based On The Apocryphal Journal Of Charles Le Raye, Neal Woodman 2015 USGS

Rafinesque’S Names For Western American Mammals, Including The Earliest Scientific Name For The Coyote (Canis Latrans Say, 1822), Based On The Apocryphal Journal Of Charles Le Raye, Neal Woodman

Neal Woodman

In 1817, the naturalist Constantine S. Rafinesque named nine new species of mammals from the American West, indicating the recently published journal of Charles Le Raye as the primary source for his descriptions. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had traveled across broad portions of the Missouri and Yellowstone river drainages a few years before the Lewis and Clark Expedition (1804–1806) traversed much of the same region. Le Raye’s journal was relied upon by generations of scholars as a valuable source documenting the native peoples and ...


Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra 2015 University of Nebraska-Lincoln

Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra

Anthropology Department Theses and Dissertations

This study employs geometric morphometric methods to investigate the morphology and shape change of the frontal bone for Pan troglodytes and Pan paniscus. Unlike previous work on the topic, this research analyzed morphology and ontogenetic shape change in a single bone of the cranium, namely the frontal bone. Frontal bone shape was compared between juvenile Pan troglodytes and Pan paniscus and the ontogeny of the bone was assessed in Pan paniscus infants and juveniles. Analyses were performed on frontal bone morphology with and without the browridge in order to assess the morphology of the frontal apart from influences affecting ...
