Predation Of Ananteris Spp. (Scorpiones: Buthidae) By Ants And A Social Wasp (Hymenoptera: Formicidae, Vespidae) In Panama, Central America, Roberto Miranda, Luis F. De Armas, Roberto A. Cambra
Euscorpius
Two events of predation on Ananteris spp. were observed in the Parque Nacional Darién, Darién Province, Panama. The first case involved the social wasp Agelaia centralis (Cameron, 1907) (Vespidae); the second one, a ponerine ant Leptogenys cf. cuneata Lattke, 2011 (Formicidae). This is the first time that predation by a social wasp on a scorpion is observed. They also represent the first recorded predators for Panamanian Ananteris species.

We describe from northern Pakistan a new buthid genus Fetilinia gen. n., monotypic with type species F. dentator sp. n., belonging to the Palaearctic ‘Buthus’ group. It bears some similarities to Kraepelinia Vachon, 1974, in having enlarged metasomal dentition, and to Orthochirus Karsch, 1891, and related genera in having a trapezoidal carapace and small abbreviated pedipalps.

Single-Locus Species Delimitation And Ecological Niche Modeling Provide Insights Into The Evolution, Historical Distribution, And Taxonomy Of The Pacific Chorus Frogs, Robert C. Jadin, Sarah A. Orlofske, Tereza Jezkova, Christopher Blair
Publications and Research
The Pacific chorus frogs are a complex of three wide-ranging species (i.e. Hyliola hypochondriaca, Hyliola regilla, Hyliola sierra) whose current taxonomy remains unresolved. We conducted species delimitation analyses of these taxa using fragments of the cytochrome b and 12S–16S mtDNA genes to assess the species diversity. Importantly, we included samples from new locations throughout the range to better understand species distributions and identify potential contact zones among clades. Our analyses revealed three slightly parapatric but distinct species-level clades. Molecular dating revealed that these species began diverging in the Pleistocene c. 1.4 Mya with H. hypochondriaca and …

An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark
Theses, Dissertations and Capstones
Polycotylidae is a family of plesiosaurian marine reptiles that evolved during the Early Cretaceous and radiated into multiple genera during the Late Cretaceous, achieving a worldwide distribution. Derived polycotylids of the subclade Polycotylinae have a gracile and elongated rostrum, homodont dentition, an extended mandibular symphysis, and foreshortened temporal fenestrae. In this thesis, I describe a small and highly derived new polycotylid taxon based on three specimens from the Campanian of the Western Interior Seaway in North America. A high number of maxillary teeth, fused neural arches, propodials with well-defined facets, and heavily remodeled cortical bone indicate the specimens are adults, …

Teaching owners how to train their dogs is an important part of maintaining the health and safety of dogs and people. Yet we do not know what behavioral characteristics of dogs and their owners are relevant to dog training or if owner cognitive abilities play a role in training success. The aim of this study is to determine which characteristics of both dogs and owners predict success in completing the American Kennel Club Canine Good Citizen training program. Before the first session of a dog training course, owners completed surveys evaluating the behavior and cognition of their dog and themselves. …

Are Capuchin Monkeys (Sapajus Spp.) Sensitive To Lost Opportunities? The Role Of Opportunity Costs In Intertemporal Choice, Elsa Addessi, Valeria Tierno, Valentina Focaroli, Federica Rossi, Serena Gastaldi, Francesca De Petrillo, Fabio Paglieri, Jeffrey R. Stevens
Jeffrey Stevens Publications
Principles of economics predict that the costs associated with obtaining rewards can influence choice. When individuals face choices between a smaller, immediate option and a larger, later option, they often experience opportunity costs associated with waiting for delayed rewards because they must forego the opportunity to make other choices. We evaluated how reducing opportunity costs affects delay tolerance in capuchin monkeys. After choosing the larger option, in the High cost condition, subjects had to wait for the delay to expire, whereas in the Low cost different and Low cost same conditions, they could perform a new choice during the delay. …

Using Audio Recording Devices And Multiseason Occupancy Modelling To Evaluate Clark's Nutcracker (Nucifraga Columbiana) Occurrence In Whitebark Pine Habitats Of Washington's Cascade Mountains, Lauren Taracka
Undergraduate Honors Theses
The Clark’s nutcracker (Nucifraga columbiana) and whitebark pine (Pinus albicaulis), both native to the harsh subalpine habitats of Washington’s Cascade Mountains, are being negatively impacted by white pine blister rust (Cronartium ribicola), the mountain pine beetle (Dendroctonus ponderosae), and climate change. As temperatures continue to warm, while many species at lower elevations can move upward in elevation to suit their temperature needs, subalpine species do not have that option. Whitebark pine is a keystone tree species - numerous animals consume its high fat, high energy seeds; it’s a nurse tree, providing shelter …

A Multispecies Perspective Into Dietary Genetic Adaptations And Ancient Migration In The Peruvian Andes, Kelsey Jorgensen
Wayne State University Dissertations
Successful adaptation to the high-elevation Andes would have required both cultural and biological adaptations by early human populations. These past adaptations continue to shape the evolutionary outcomes of both humans and non-human species today. A multispecies perspective was used to examine how humans and non-human creatures, specifically insects, were shaped by past human adaptations. This dissertation asked two primary questions: 1) Given the importance and evolutionary history of potato consumption in the Peruvian Andes, is a genetic adaptation to better digest potato starch detectable in present-day Peruvians? and 2) Using the Andean Potato Weevil (APW) phylogeny as a proxy, what …

Morphological Variance In Mouthparts And Foraging Behavior In Bumblebees, Ye Jin Lee
Honors Theses
Bumblebees (Hymenoptera: Apidae: Bombus) show an incredible degree of size variation within and between species. Individuals from the same hive may vary up to 10-fold in mass. This variation allows individuals to specialize in foraging on different flowers suited to their morphology. However, as different species have different foraging behaviors, their variation in mouthparts and scaling of mouthparts to body size may have been under different kinds of stabilizing selection as they adapted to collect nectar from flowering plants over evolutionary time. Here, we examined the scaling relationships between body size and mouthpart structures, and the variation in mouthpart shape …

Lynn Margulis And Boris Kozo-Polyansky: How The Symbiogenesis Was Translated From Russian, Victor Fet
Biological Sciences Faculty Research
This contribution details the complex history of the early work by Boris Kozo-Polyansky (1924) that became available in English translation 86 years after it was published in Russian. The great American naturalist Lynn Margulis—whose serial endosymbiosis theory was presciently predated by Kozo-Polyansky by four decades—was instrumental in organizing this resurrection and ‘horizontal transfer’ of knowledge, forgotten by that time even in Russia.

In Search Of Hidden Talents : Stress-Adapted Students, Classroom Characteristics, And Academic Achievement, Jessica Lynn Murray
Legacy Theses & Dissertations (2009 - 2024)
Differentiated Instruction, an approach to teaching that encourages educators to adjust their content, pedagogy, and assessment based on the needs of individual students, lacks suggestions for how to target specific student groups, such as “high-risk” students. Researchers in the field of evolutionary developmental psychology have begun to focus on stress-adapted students (who are described in a similar way as “high risk” students) and has made suggestions about how to play to the strengths of the cognitive enhancements, or “hidden talents” of these students. When considered together, the work from both fields may provide a clear set of pedagogical recommendations for …

Faculty Journal Articles
In Pennsylvania Baptisia australis var. australis is found along only four waterways: the Allegheny River, Youghiogheny River, Clarion River, and Red Bank Creek. Because of its limited distribution and small number of extant populations, the species is considered state-threatened in Pennsylvania. In addition, the riparian prairie habitat that Pennsylvania Baptisia australis var. australis is restricted to is also in decline and considered vulnerable. Because of these conservation concerns, insights into the natural history of the taxon in the state is valuable and will inform conservation efforts. Field surveys and fruit collections along the Allegheny River and herbarium collections were used …

How Bavinck Responds To The Challenges Of The Theory Of Evolution: The Primacy Of Biblical Revelation, Isaias D'Oleo Ochoa
CTS Student Publications and Creative Works
In his discussion of evolution, Bavinck offers a modified theory of development, rooted not under a mechanistic and naturalistic worldview, as Darwin does, but under a “theistic-friendly” framework. This article argues that Bavinck’s discussion of evolution as a whole endorses a modified Aristotelian/ Thomistic framework in order to understand the theory of development, and thus overcomes the challenges raised by Darwin’s naturalistic worldview to biblical revelation.

Climate Niche Evolution In C4+Cam Portulaca And Closely Related C3+Cam Lineages, Nora M. Heaphy
Library Map Prize
With at least a hundred independent origins among land plants, the CAM and C4 photosynthetic pathways represent one of the most notable examples of global convergent evolution of a complex trait. While biochemically similar, CAM and C4 are generally understood to be two distinct ecological adaptations evolving along separate trajectories. However, the purslanes (Portulaca), a globally widespread clade of around 100 species of annual and perennial succulents, are able to operate both CAM and C4 cycles in the same leaf. Portulaca likely originated from a facultative CAM ancestor and then evolved a C4 system at least three times …

Alfred Russel Wallace Notes 15. Wallace's Many "Hats": What Should We Call Him?, Charles H. Smith
Faculty/Staff Personal Papers
Alfred Russel Wallace (1823−1913) has been referred to by name through the aid of a variety of labels – some thirty or more, in fact – that link him to his emphases of attention. How many of these labels are/were justifiable? The assessment here is that he is probably best remembered as a ‘naturalist,’ ‘geographer,’ ‘evolutionist,’ and ‘social critic.’

Initial And Advanced Stages Of Microbiota Establishment Within The Tsetse Fly, Miguel Eduardo Medina Munoz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Symbiosis is a long-term physical association between two or more species, although little is known regarding its evolutionary origins, particularly at the genetic level. Tsetse flies are the vector of African trypanosomes, causative agents of Human and Animal African Trypanosomiases. Tsetse provide an ideal model for studying initial and advanced stages of symbiosis. Tsetse have a simple digestive tract microbiota primarily consisting of two bacteria; the ancient mutualist Wigglesworthia glossinidia and the recently acquired Sodalis glossinidius. This work presents a chronological study in evolutionary terms of the history of a microbial-insect association. First, I present concepts on symbiosis and …

Alfred Russel Wallace Notes 8: Wallace's Earliest Exposures To The Writings Of Alexander Von Humboldt, Charles H. Smith
Faculty/Staff Personal Papers
For many years it has been known that the German geographer and naturalist Alexander von Humboldt (1769-1859) exercised a considerable influence on Alfred Russel Wallace’s (1823-1913) decision to become a travelling naturalist. Almost no attention, however, has been given to the real possibility that von Humboldt exerted an even greater influence on Wallace’s general worldview. In this note, Wallace’s probable earliest contacts with von Humboldt’s writings are described.

Exploring Zosterophyll Relationships Within A More Broadly Sampled Character Space: A Focus On Anatomy, Megan Nibbelink
Cal Poly Humboldt theses and projects
Important constituents of Siluro-Devonian floras, zosterophylls gave rise to the lycophytes. I explore the relationships of 18 zosterophyll species from 16 genera, maximizing sampling of anatomy. Using phylogenetic and phenetic methods, I (1) assess the influence of tree rooting, taxon sampling, and morphological vs anatomical characters on the stability of relationships; and (2) compare phylogenetic and phenetic methods in terms of relationships recovered. Phenetic analyses show sensitivity to taxon sampling and support placement of Renalia among zosterophylls, but do not provide results that are strongly congruent with those of phylogenetic analyses. Phylogenetic analyses demonstrate that taxon and character sampling significantly …

Comparative Conservation Genomics Of A Suite Of Imperiled Freshwater Mussels, Scott C. Meyer
College of Graduate Studies: Theses & Dissertations
Maintenance of genetic diversity is a critical component to the management and recovery of imperiled species. By ensuring that a species’ genetic diversity is maintained, issues like inbreeding depression and loss of local adaptation can be prevented. However, the genetic diversity of many species are not well-characterized, and the factors that influence a species’ genetic diversity are often not well understood. In the case of imperiled unionid freshwater mussels, it is important to conduct conservation genetic assessments to aid in their management and preserve genetic diversity. This is the first study to conduct a comparative conservation genomic assessment for eight …
