Nurudea Zhengii Ren, A New Species Of The Rhus Gall Aphids (Aphididae: Eriosomatinae: Fordini) From Eastern China, Zhu-Mei Ren, Xu Su, Carol D. Von Dohlen, Jun Wen
Nurudea Zhengii Ren, A New Species Of The Rhus Gall Aphids (Aphididae: Eriosomatinae: Fordini) From Eastern China, Zhu-Mei Ren, Xu Su, Carol D. Von Dohlen, Jun Wen
Biology Faculty Publications
A new Rhus gall aphid species Nurudea zhengii Ren, sp. nov. collected from the Mountain Qixing in Shangrao County, Jiangxi Province, China is described and illustrated from alate viviparous female. The new species differs from the other Nurudea species in the length and proportion of antennal segments, the structure of antennal secondary sensilla, and the flower-like shape of the galls that are formed on its primary host. Its primary host plant is Rhus hypoleuca, whereas other Nurudea species are on R. chinensis.

Despite their diversity and ecological importance, many areas of the SAR—Stramenopila, Alveolata, and Rhizaria—clade are poorly understood as the majority (90%) of SAR species lack molecular data and only 5% of species are from well-sampled families. Here, we review and summarize the state of knowledge about the three major clades of SAR, describing the diversity within each clade and identifying synapomorphies when possible. We also assess the “dark area” of SAR: the morphologically described species that are missing molecular data. The majority of molecular data for SAR lineages are characterized from marine samples and vertebrate hosts, highlighting the need for …
The Mechanism Of Biotremor Production In The Veiled Chameleon (Chamaeleo Calyptratus), Samuel Tegge
The Mechanism Of Biotremor Production In The Veiled Chameleon (Chamaeleo Calyptratus), Samuel Tegge
Masters Theses & Specialist Projects
Vibratory communication has evolved in numerous animal groups, including insects, spiders, fishes, mammals, and was recently discovered in veiled chameleons (Chamaeleo calyptratus). I examined the mechanism by which C. calyptratus produce these biotremors. Muscle activity data were gathered during simulated anti-predator responses via electromyography (EMG) with simultaneous recordings of biotremor production using an accelerometer. I correlated EMG data with the accelerometer data to implicate the muscles responsible for the production of the biotremors. Mixed-effect linear regression models described the mechanism, and a model selection framework determined which model fit the data best. I then used an analysis of variance to …
How The Egg Rolls: A Morphological Analysis Of Egg Shape In The Context Of Displacement Dynamics, Ian R. Hays
How The Egg Rolls: A Morphological Analysis Of Egg Shape In The Context Of Displacement Dynamics, Ian R. Hays
Theses and Dissertations
Very little is known about how morphology effects the motion, stability and the resulting viability of avian eggs. The limited research that exists focuses on the pyriform or ‘pointed’ egg shapes found in the Alcidea family. This unusual shell form is thought to suppress displacement and prevents egg loss on the cliffside nesting habitat of the Uria genera. Unfortunately, these studies never isolated or quantify the specific morphological features (elongation, asymmetry and conicality) of these pyriform eggs, which limits their applicability to other taxa and hampers a robust proof of concept. We isolated each feature as a variable, produced models …
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
Theses, Dissertations and Capstones
Coyotes (Canis latrans) are now found throughout North and Central America, but before European colonization were restricted to west of the Mississippi. Migration occurred in two major paths to the East; north over the Great Lakes (through Canada) and south below the Great Lakes. The location of these routes is significant because those migrating north interbred with the wolves that reside there. These hybrid animals are larger and behaviorally different from their western counterparts. It is possible to differentiate these hybrids morphologically and genetically. Hybrids are known to be located in Maine, New York, and Pennsylvania, but the interest of …
Leptodactylus Validus Garman, 1888 In Colombia: Its Distribution And Identification, Andres R. Acosta Galvis, Rafael O. De Sá
Leptodactylus Validus Garman, 1888 In Colombia: Its Distribution And Identification, Andres R. Acosta Galvis, Rafael O. De Sá
Biology Faculty Publications
Leptodactylus validus is reported for the first time for Colombia, corresponding to the tenth species of the L. melanonotus species group occurring in the country. In collections, all L. validus specimens were identified as L. colombiensis. Morphological, coloration, and ecological characters are provided to differentiate the two species in Colombia. Furthermore, the distribution of L. validus is expanded based on the examination of specimens in both collections and literature records. In addition, the advertisement call of L. validus from Colombia is compared with those reported for other continental and insular populations; the calls are slightly more similar to those …
Morphological And Behavioral Traits Associated With Locomotion In Lizards, Chase T. Kinsey
Morphological And Behavioral Traits Associated With Locomotion In Lizards, Chase T. Kinsey
Electronic Theses and Dissertations
Morphology, locomotion, and behavior are co-adapted to optimize performance and ultimately fitness. Successfully navigating a complex environment is dictated by an animal’s locomotor behavior, and for some behaviors, its locomotor performance. The locomotor performance of an organism is directly related to the form and function of the structures involved in locomotion such that movement is efficient – that is, minimal loss of energy. The first chapter of this thesis focuses on the effects of obstacle placement and forelimb position on facultative bipedalism. Placing an obstacle beyond a lizard’s acceleration threshold did not affect the frequency of bipedal posture. Furthermore, the …
