Euscorpius
Hemiscorpius shahii sp. n. from Iran, Hormozgan Province, is described and compared with other species of Hemiscorpius genus. The new species is characterized mainly by total length of 84 (female) to 110.7 (male) mm and unique trichobothrial pattern of pedipalp patella. The number of external trichobothria on patella is 17–18 (5 eb, 4 esb, 2–3 em, 3 est, 3 et); the number of ventral trichobothria on patella is 14–16. This distinguishes H. shahii sp. n. from all other species of genus Hemiscorpius, which have 3 or 10–12 ventral trichobothria on patella, one or …

The Interommatidial Bristle Variability Of Diptera, Kimberly Palmer
Honors College Theses
Insects of the order Diptera are a popular biological model for understanding morphological trait evolution. One area of particular interest is the development of the compound eyes. While the development of ommatidia and photoreceptors has been thoroughly studied in this case, little attention has been paid to the interommatidial bristles (IOBs) present on the eyes of some dipteran families. A preliminary survey suggested that these bristles exhibit high variability among IOB families on multiple taxonomic levels and are not uniformly present or absent in any suborder of the Diptera. To confirm this observation, I conducted a literature search to …

Ecological Niche Modeling Of The Genus Papio, Amanda J. Fuchs
Theses and Dissertations
Ecological niche modeling investigates how climatic variables have influenced taxonomic diversity in Papio. Models performed well suggesting climatic variables influence the distribution of baboon species. Niche overlap among all possible pairs of taxa determined that species exhibited significantly different niches. The results of these models support a parapatric speciation scenario.

Fleas Of The American Pika: Diversity And Biogeography In North America’S Intermountain West, Niyomi Wijewardena
All NMU Master's Theses
American pikas (Ochotona princeps) are small mammals that are widely distributed across North America’s Intermountain West. Previous investigations revealed five geographically distinct mitochondrial lineages within O. princeps associated with different mountain systems of the Intermountain West. In contrast, diversity of endoparasitic helminths of pikas is not structured geographically in the same way. Instead, there are two primary parasite assemblages, one distributed across southwestern pika populations and one found across the northeastern part of the host range. These contrasting patterns suggest that the shared history of pikas and their parasites had different consequences for the evolutionary trajectories of these …

Revalidation Of Three Recently Synonymized Cuban Species Of Heteroctenus Pocock, 1893 (Scorpiones: Buthidae: Centruroidinae), Luis F. De Armas
Euscorpius
The scorpion genus Heteroctenus Pocock, 1893 was restored from synonymy with Rhopalurus in a recent revision by Esposito et al. (2017). Here, we restore two eastern Cuban species Heteroctenus melloleitaoi (Teruel et Armas, 2006) and H. aridicola (Teruel et Armas, 2012) as valid species. They were synonymized by Esposito et al. (2017) under Heteroctenus junceus (Herbst, 1800), without examination of corresponding specimens and with erroneous interpretations of some aspects of the original descriptions. Heteroctenus granulimanus (Teruel, 2006) is also restored as a valid species. The subfamily Rhopalurusinae Bücherl, 1971 is regarded as a junior synonym of Cen-truroidinae Kraus, 1955.

Euscorpius
We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.

Ethical Theories And Perspectives On End-Of-Life Decisions, Lauren Skelton
Dialogue & Nexus
This paper approaches several different ethical theories to see how they interact with the issue of withdrawing and withholding life-sustaining care. After the theories of Utilitarianism, Kantian and Prima Facie Deontology, Virtue Ethics, and Evolutionary Ethics are explored at length, Deontological theories are proven to be the best decision-making guide from the perspective of both patients and those in policy-making positions. When used together, Kantian and Prima Facie Deontology offer the overall best combination of ethical instruction and personal freedom.

Ecofeminism: The Path Towards Healing The Earth, Jamie Thompson
Dialogue & Nexus
The concept of the patriarchy, or any concept in which one group dominates another, is inseparable from the formation of human kind’s domination of nature. This domination of nature has led to the current the ecological crisis humanity faces. Those who deny climate change can admit to the massive amounts of pollution, trash, and deforestation. Despite this worsening economic crisis, those in power have been slow to react. Women can ultimately provide and lead the movement to solve this ecological crisis through the growing movement of Ecofeminism. In the philosophy of Ecofeminism, individuals recognize and reject western dualistic thinking that …

The Origins Of Morality, Paulina Sanchez
Dialogue & Nexus
In modern society, there exists a standard for moral conduct that seems to reign universal over many societies of people. Pinpointing the origins of morality, however, can become problematic because of how one approaches what morality is and what its purpose is in society. Psychologists may point out the social constructs and norms that allow for morality to unfold. Evolutionary biologists may give evidence of human-related species that have developed similar behavioral standards. A Christian theologian may look to scripture in explaining a Creator who ordained that all abide by the standards of conduct most pleasing to this deity. Which …

The Altruistic Self, Nathan Dougherty
Dialogue & Nexus
Altruism as a purely naturalistic phenomenon self-defeats the term altogether; however, theology also makes unsubstantiated claims that some behaviors are purely selfless. I will first define various conceptual forms of altruism and then offer explanations of the term from neurological, evolutionary and psychological investigations. Despite the position that altruism can be reduced to a fantastical impossibility bearing neither the arms of science nor theology, it is also a fallacy to separate it from a religiously derived supernatural altruism that carries no implications for the realm of morality.
A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors,

A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors, Kristin Kaiser
Dialogue & Nexus
The definition of altruism has been studied, explained, and even confused by many scholars in various fields. The term itself has been inappropriately used to describe prosocial behaviors that do not fall within the definition of altruism. An evaluation of Grant Ramsey’s taxonomy of altruism, which includes biological altruism, psychological altruism, and helping altruism, proves that it is not adequate in categorizing organism’s behaviors. A new taxonomy, with the branches of kin selection, reciprocity, and aesthetic altruism, is presented and explained to clarify the definition of altruism and alleviate confusion about how to describe prosocial behaviors. Both naming systems are …

The Evolutionary Theodicy Problem, Houston Schoonmaker
Dialogue & Nexus
Evolutionary theodicies attempt to explain how innocent suffering, death, and extinction seen throughout the evolutionary process of evolution can coincide with believing in a loving God. Since Darwin, scholars have questioned the importance of studying natural selection at such an intricate level. With the knowledge of natural selection, the fact that great suffering is witnessed across nature permits doubts in discussions regarding a benevolent God that created the universe. In this paper, I begin with background information about evolution, theodicy, and how they are related. I look at two major perspectives: the belief that evolution ameliorates the theodicy problem or …

Neuroscience, Materialism, And The Soul: Limit Questions, Jeremy M. Aymard
Dialogue & Nexus
In light of recent discoveries in neuroscience linking the mind to physical processes, Christian philosophers have resorted to a more materialistic view of the human person, using neuroscience as support for their view that an immaterial soul does not exist. In this essay, I will point out a major flaw in the logic for defending a materialistic view, argue that either a bipartite or tripartite view of the human person is more aligned with Scripture, and hopefully point towards a more reliable means for attaining truth regarding human nature and the soul.

Intelligent Design: Should We Teach It?, Sarah-Kate Oliver
Dialogue & Nexus
Belief about the origins of the universe and mankind is an important aspect of most world religions. While many ‘progressive’ Christians view the Genesis accounts of creation as mythical or allegorical, some ‘fundamentalist’ Christians claim it is a literal and historical account of the origins of life. The scientific community, on the other hand, views Darwin’s Theory of Evolution as the definitive explanation of the origin of all species on Earth including humans. As science has continued to line up behind evolution, it has been integrated into the public school curriculum. The question examined by this paper is: should the …

A Global Community Effort To Decipher The Unique Biology Of Annual Killifish, Nibia Berois, Graciela Garcia, Rafael O. De Sá
Biology Faculty Publications
Over the past 50 years, annual killifishes arose as alternative model organisms for studies of vertebrate biology. The annual fish offers exceptional advantages for studies of genetics, genomics, developmental biology, population dynamics, ecology, biogeography, and evolution. They inhabit extremely variable freshwater environments in Africa and South America, have a short lifespan and a set of unique and fascinating developmental characteristics. Embryos survive within the dry substrate during the dry season, whereas the adult population dies. Thus, the survival of the populations is entirely dependent on the buried embryos that hatch the next rainy season. Although Old and New World species …

Euscorpius
The African monotypic scorpion genus Microananteroides Rossi et Lourenço, 2015 and its single species M. mariachiarae Rossi et Lourenço, 2015, from Ghana, are herein demonstrated to be junior synonyms, respectively, of Akentrobuthus Lamoral, 1976 and A. atakora Vignoli et Prendini, 2008 from neighboring Benin. We provide detailed high-resolution color photographs of the holotype of M. mariachiarae and further show its real tri-chobothrial pattern, which was incorrectly depicted in the original description.

Ecology, Evolution, And Sexual Selection In The Invasive, Globally Distributed Small Indian Mongoose (Urva Auropunctata), M. Aaron Owen
Dissertations, Theses, and Capstone Projects
Introduced species provide rare opportunities to test evolutionary hypotheses in situ by creating so-called natural experiments. Natural experiments are situations in nature that resemble laboratory studies by allowing for comparisons of a “control” group (i.e., a species’ native range) with “experimental” groups (i.e., a species’ introduced range). In particular, introduced animals allow us to investigate evolutionary dynamics in complex, long-lived organisms in ways that would otherwise be impossible in a laboratory setting. One such introduced animal is the small Indian mongoose (Urva auropunctata, formerly Herpestes auropunctatus). Native to South Asia, the small Indian mongoose’s introduction to more …

Experimental Evolution With Caenorhabditis Nematodes, Henrique Teotónio, Suzanne Estes, Patrick C. Phillips, Charles F. Baer
Biology Faculty Publications and Presentations
The hermaphroditic nematode Caenorhabditis elegans has been one of the primary model systems in biology since the 1970s, but only within the last two decades has this nematode also become a useful model for experimental evolution. Here, we outline the goals and major foci of experimental evolution with C. elegans and related species, such as C. briggsae and C. remanei, by discussing the principles of experimental design, and highlighting the strengths and limitations of Caenorhabditis as model systems. We then review three exemplars of Caenorhabditis experimental evolution studies, underlining representative evolution experiments that have addressed the: (1) maintenance of genetic …

The purpose of this genetic study of the Santa Ana Speckled Dace Rhinichthys osculus was three-fold. The first goal was to characterize the molecular structure of the mtDNA control region of R. osculus. An 1143 base-pair region of the mitochondrial DNA genome, which included the complete control region was sequenced for all individuals. Analysis of the sequence data revealed that the molecular structure of the speckled dace control region was similar to the molecular structure described for other vertebrate taxa. The speckled dace control region contains three major domains, which vary in base frequency as well as in the frequency …
