Is Superiority A Necessary Aspect Of Cruelty?, William H. Edmondson
Is Superiority A Necessary Aspect Of Cruelty?, William H. Edmondson
Animal Sentience
Chapman & Huffman argue that humans inflict cruelty without apparent concern because of their categorization of the victims as inferior. The supposed inferiority of non-human animals can be argued against on the basis of documentation and analysis of behaviour. Humans continue to inflict cruelty on their own and other species. It is not obvious that a sense of superiority is a necessary aspect of cruel behaviour. Nor is it obvious that further enlightenment regarding the cognitive status of non-humans will diminish cruelty.
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
Animal Sentience
We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.
Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms
Comparative Study Of Spinning Field Development In Two Species Of Araneophagic Spiders (Araneae, Mimetidae, Australomimetus), Mark A. Townley, Danilo Harms
Molecular, Cellular & Biomedical Sciences
External studies of spider spinning fields allow us to make inferences about internal silk gland biology, including what happens to silk glands when the spider molts. Such studies often focus on adults, but juveniles can provide additional insight on spinning apparatus development and character polarity. Here we document and describe spinning fields at all stadia in two species of pirate spider (Mimetidae: Australomimetus spinosus, A. djuka). Pirate spiders nest within the ecribellate orb-building spiders (Araneoidea), but are vagrant, araneophagic members that do not build prey-capture webs. Correspondingly, they lack aggregate and flagelliform silk glands (AG, FL), specialized for forming prey-capture …

Euscorpius
Pandinops platycheles (Werner, 1916) is diagnosed and fully complemented with color photos of types, and Pandinops pugilator (Pocock, 1900) is diagnosed and fully complemented with color photos of live and preserved specimens, as well as its habitat. The hemispermatophore of P. pugilator is illustrated and described for the first time. Pandinus hawkeri Pocock, 1900 and Pandinus peeli Pocock, 1900 are synonymized with Pandinops pugilator (Pocock, 1900).

(Scorpionidae) From Somaliland And A Review Of Type Locality And True Distribution Of Pandinurus Smithi (Pocock, 1897), František Kovařík, Graeme Lowe, Tomáš Mazuch, Ahmed Ibrahim Awale, Jana Štundlová, František Šťáhlavský
Euscorpius
Pandinurus hangarale sp. n. from Somaliland is described and fully complemented with color photos of live and preserved specimens, as well as its habitat. Hemispermatophore of P. hangarale sp. n. is illustrated and described. In addition to the analyses of external morphology and hemispermatophores, we also describe the karyotype of P. hangarale sp. n. (2n=120). Known localities of Pandinurus smithi (Pocock, 1897) are compiled; the type locality is not in Somaliland but in Ethiopia (Turfa) and in reality it is probably an endemic of Ethiopia.
A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers
A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers
Euscorpius
Herein we describe a new species of the Buthidae scorpion genus Centruroides Marx, 1890. It occurs at least in two small offshore islands of the southwestern Caribbean: Cozumel in Mexico and Guanaja in Honduras, based upon type specimens from the former and photographic evidence from the latter. It belongs in the "gracilis" species-group and is most closely related to both Centruroides gracilis (Latreille, 1805) and Centruroides nigrescens (Pocock, 1898).

Cryptic Diversity And Discordance In Single‐Locus Species Delimitation Methods Within Horned Lizards (Phrynosomatidae: Phrynosoma), Christopher Blair, Robert W. Bryson Jr.
Publications and Research
Biodiversity reduction and loss continues to progress at an alarming rate, and thus there is widespread interest in utilizing rapid and efficient methods for quantifying and delimiting taxonomic diversity. Single-locus species-delimitation methods have become popular, in part due to the adoption of the DNA barcoding paradigm. These techniques can be broadly classified into tree-based and distance-based methods depending on whether species are delimited based on a constructed genealogy. Although the relative performance of these methods has been tested repeatedly with simulations, additional studies are needed to assess congruence with empirical data. We compiled a large data set of mitochondrial ND4 …

Catalinia, A New Scorpion Genus From Southern California, Usa And Northern Baja California, Mexico (Scorpiones: Vaejovidae), Michael E. Soleglad, Richard F. Ayrey, Matthew R. Graham, Victor Fet
Euscorpius
Genus Catalinia, gen. nov. (Scorpiones: Vaejovidae) is described from southern California, USA and Baja California, Mexico. The genus is composed of four species formerly placed in Pseudouroctonus: Catalinia minima (Kraepelin, 1911), comb. nov. (type species), C. andreas (Gertsch et Soleglad, 1972), comb. nov., C. castanea (Gertsch et Soleglad, 1972), comb. nov., and C. thompsoni, comb. nov. (Gertsch et Soleglad, 1972). Major diagnostic characters of Catalinia include a carapace with a very weak anterior indentation, a very stout metasoma with little or no tapering from segment I to V, and a mating plug with two partial bases. …
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
Zea E-Books Collection
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly …
The Inconvenient Truth About Thinking Chickens, Lori Marino
The Inconvenient Truth About Thinking Chickens, Lori Marino
Animal Sentience
Original Abstract: Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. Some birds are now known to be on a par with many mammals in their intelligence, emotional sophistication, and social interaction. Yet views of chickens have largely remained unrevised in light of this new evidence. In this paper, I examine the data on cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities with other birds and other vertebrates, particularly …
The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), Rolando Teruel, Mel J. Rivera, Alejandro J. Sánchez
The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), Rolando Teruel, Mel J. Rivera, Alejandro J. Sánchez
Euscorpius
The scorpion fauna of the small Mona Island (= Isla de Mona), located roughly midway between Hispaniola and Puerto Rico and administratively belonging to the latter, is herein revised. Three species are confirmed to occur: the buthids Centruroides bani Armas et Marcano Fondeur, 1987 and Heteroctenus abudi (Armas et Marcano Fondeur, 1987), plus the diplocentrine scorpionid Cazierius garridoi Armas, 2005. The previously recorded Heteronebo sp. is reexamined and deemed a mislabeled specimen of Heteronebo portoricensis Francke, 1978 from adjacent Puerto Rico. Also, Centruroides mariaorum Santiago-Blay, 2009 is demonstrated to be a junior synonym of C. bani (implying the first demonstrable …

Hemiscorpius Shahii Sp. N. From Iran (Scorpiones: Hemiscorpiidae), František Kovařík, Shahrokh Navidpour, Michael E. Soleglad
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 …
Revalidation Of Three Recently Synonymized Cuban Species Of Heteroctenus Pocock, 1893 (Scorpiones: Buthidae: Centruroidinae), Luis F. De Armas
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.
The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin
The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin
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.
A Global Community Effort To Decipher The Unique Biology Of Annual Killifish, Nibia Berois, Graciela Garcia, Rafael O. De Sá
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 …
Microananteroides Mariachiarae Rossi Et Lourenço, 2015 Is A Junior Synonym Of Akentrobuthus Atakora Vignoli Et Prendini, 2008 (Scorpiones: Buthidae), František Kovařík, Rolando Teruel, Graeme Lowe
Microananteroides Mariachiarae Rossi Et Lourenço, 2015 Is A Junior Synonym Of Akentrobuthus Atakora Vignoli Et Prendini, 2008 (Scorpiones: Buthidae), František Kovařík, Rolando Teruel, Graeme Lowe
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.

We describe and illustrate in detail the previously unknown adult male of Ananteris ashaninka Kovařík, Teruel, Lowe et Friedrich, 2015, based upon a specimen recently captured at the type locality. In addition, the taxonomic status of three Amazonian species of the genus Tityus C. L. Koch, 1836, is reevaluated and all are restored from unjustified synonymies: Tityus carolineae Kovařík, Teruel, Cozijn et Seiter, 2013, Tityus dillerorum Kovařík, Teruel, Lowe et Friedrich, 2015, and Tityus wachteli Kovařík, Teruel, Lowe et Friedrich, 2015.
Breeding Stage And Parentage Affect Tameness In Common Loons, Mina Ibrahim
Breeding Stage And Parentage Affect Tameness In Common Loons, Mina Ibrahim
Student Scholar Symposium Abstracts and Posters
Tameness is a measure of tolerance towards human disturbance. As human disturbance and recreational activity are increasing, it is becoming more and more important to understand responses of species to this disturbance. Tameness has been shown to be influenced by an individuals characteristics and life history. Two possible determinants of tameness are breeding stage and parentage. We studied tameness in common loons (Gavia immer) specifically looking at the effects of breeding stage and parentage. Tameness was measured by flight initiation distance (FID), the distance at which a loon dove from an approaching human observer in a canoe. Loons …
First Record Of Centruroides Alayoni Armas, 1999 (Scorpiones: Buthidae) From Haiti, Greater Antilles, Luis F. De Armas

Euscorpius
Centruroides haitiensis Lourenço, 2016, from Grande Cayemite, Haiti, is regarded as a junior synonym of Centruroides alayoni Armas, 1999, previously known from southern Pedernales Province (215 km east of Grande Cayemite), Dominican Republic. Consequently, C. alayoni is herein recorded for the first time from Haiti. The list of the Haitian species of the genus Centruroides Marx, 1890 is given.

Body Shape Diversification Of Pecos Pupfish (Cyprinodon Pecosensis) On Varying Habitats As Evaluated By Geometric Morphometrics, Qianna Xu
Masters Theses & Specialist Projects
During the 19th and 20th centuries, alterations to the Pecos River in New Mexico and Texas, USA due to anthropogenic activities, including damning and river channelization, vast water extraction for irrigation, as well as pollution of associated habitats, have greatly impacted the fish fauna within the drainage. One of the endemic fish species, the Pecos pupfish (Cyprinodon pecosensis), might be the most affected. Historically abundant and widespread large populations have been disrupted and became a series of small isolated subpopulations that persist at a few highly fragmented habitats restricted to a small area in southern New Mexico. The connectivity among …
Some Taxonomic Corrections To The Genus Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) In Hispaniola, Greater Antilles, Rolando Teruel
Some Taxonomic Corrections To The Genus Tityus C. L. Koch, 1836 (Scorpiones: Buthidae) In Hispaniola, Greater Antilles, Rolando Teruel
Euscorpius
In the present paper, the taxonomic status of several Hispaniolan members of the genus Tityus C. L. Koch, 1966 is revised after examination of almost all primary types and abundant supplementary material. This resulted in six new synonymies, which involve both extant and fossil species. The extant taxa herein synonymized are Tityus anasilviae Armas et Abud, 2004 under Tityus ottenwalderi Armas, 1999, Tityus bahoruco Teruel et Armas, 2006 under Tityus crassimanus (Thorell, 1876), Tityus ebanoverde Armas, 1999 under Tityus elii Armas et Marcano, 1992, and Tityus septentrionalis Armas et Abud, 2004 under Tityus portoplatensis Armas et Marcano, 1992.

Patterns Of Morphological And Molecular Evolution In The Antillean Tree Bat, Ardops Nichollsi (Chiroptera: Phyllostomidae), Roxanne J. Larsen, Peter A. Larsen, Caleb D. Phillips, Hugh H. Genoways, Gary G. Kwiecinski, Scott C. Pedersen, Carleton J. Phillips, Robert J. Baker
University of Nebraska State Museum: Mammalogy Papers
Species endemic to oceanic islands offer unique insights into the mechanisms underlying evolution and have served as model systems for decades. Often these species show phenotypic variation that is correlated with the ecosystems in which they occur and such correlations may be a product of genetic drift, natural selection, and/or environmental factors. We explore the morphologic and genetic variation within Ardops nichollsi, a species of phyllostomid bat endemic to the Lesser Antillean islands. Ardops nichollsi is an ideal taxon to investigate the tempo of evolution in Chiroptera, as it: is a recently derived genus in the family Phyllostomidae; contains …

Thelytokous parthenogenesis (all-female broods) is strongly suggested for the vaejovid species Serradigitus miscionei (Vaejovidae) from southern Arizona, USA. This conclusion is based on the examination of 187 specimens and 15 broods, all determined as females.
The Missing Piece Of The Puzzle Solved: Heteronebo Pocock, 1899 (Scorpiones: Scorpionidae) Occurs At Isla De Pinos, Cuba, Rolando Teruel, Tomás M. Rodríguez-Cabrera
The Missing Piece Of The Puzzle Solved: Heteronebo Pocock, 1899 (Scorpiones: Scorpionidae) Occurs At Isla De Pinos, Cuba, Rolando Teruel, Tomás M. Rodríguez-Cabrera
Euscorpius
The diplocentrine scorpion genus Heteronebo Pocock, 1899 is recorded herein for the first time from Isla de Pinos, southwestern Cuba. A total of 15 specimens of Heteronebo bermudezi (Moreno, 1938) were collected in two nearby localities of the southern coast of the island, where it occurs in exactly the same habitat previously known for this species in Guanahacabibes Peninsula and two cays of Canarreos Archipelago. The allegedly polytypic status of this species is also revised and full species rank is restored to the subspecies Heteronebo bermudezi morenoi (Armas, 1973). An updated distribution map of H. bermudezi is provided.
Use Of Erroneous Wolf Generation Time In Assessments Of Domestic Dog And Human Evolution, L. David Mech
Use Of Erroneous Wolf Generation Time In Assessments Of Domestic Dog And Human Evolution, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
Scientific interest in dog domestication and parallel evolution of dogs and humans (1) has increased recently (2-4), and various important conclusions have been drawn based on how long ago the calculations show dogs were domesticated from ancestral wolves (Canis lupus). According to Skoglund et al. (2015:3), calculation of this duration is based on “the most commonly assumed mutation rate of 1 x 10-8 per generation and a 3-year gray wolf generation time . . .” (5). It is unclear on what information the assumed generation time is based, but the latest paper (6) seems to have based generation time on …
Centruroides Thorellii (Scorpiones: Buthidae): Traveling From Guatemala To England Without A Passport, Rony E. Trujillo, Luis F. De Armas, Darren Mansfield
Centruroides Thorellii (Scorpiones: Buthidae): Traveling From Guatemala To England Without A Passport, Rony E. Trujillo, Luis F. De Armas, Darren Mansfield
Euscorpius
We recorded a pregnant female of the Central American bark stripped scorpion Centruroides thorellii (Kraepelin, 1891), which arrived to England as a stowaway in the bag of a woman that previously visited the Departments of Sacatepéquez, Sololá and San Marcos, Guatemala. On January 2, this C. thorellii female had a litter of three off-spring and three infertile eggs, but she has eaten them, probably as consequence of the stress caused by the hard travel and the environmental changes. We provide a map with the geographical distribution of this species and photos of the female detected in a British train.

A New Species Of The “Apacheanus” Group Of Genus Pseudouroctonus From Western Texas (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad
Euscorpius
A new species of the “apacheanus” group of genus Pseudouroctonus is described from western Texas, USA, Pseudouroctonus brysoni, sp. nov. This new species is closely related to P. apacheanus (Gertsch et Soleglad, 1972) and two other species recently described from southern Arizona. A combination of morphological differences in the hemispermatophore, the mating plug, and several morphometric-based characters are identified as diagnostic.
Raising Consciousness About Chicken Consciousness, Bernard Rollin
Raising Consciousness About Chicken Consciousness, Bernard Rollin
Animal Sentience
The topics explored by Marino are definitive, and should work well to lay to rest forever the widespread belief that chickens have no personality, are unintelligent, or in any other way lack a mental life.
