Historical Chaos Among Tetrabothriideans (Eucestoda) Of Odontocetes (Artiodactyla)—Revising Generic Taxonomy And Species Diversity For Cestodes Among Oceanic Dolphins, Eric P. Hoberg, Kaylen Marie Soudachanh, Robert L. Rausch

MANTER: Journal of Parasite Biodiversity

Explorations over the past 150 years that have defined the diversity and structure of the tetrabothriidean cestode fauna among Odontocete cetaceans (Artiodactyla) are summarized and reviewed. Persistent errors in interpretation of comparative morphological characters, inconsistent taxonomic decisions, and an understanding of generic-level and species diversity are addressed. We outline a revision of the Tetrabothriidea, which now encompasses 8 genera. Prosthecocotyle is resurrected from synonymy with Tetrabothrius, and Cetaceobothridius n. gen is proposed. A clear basis is outlined for differentiation of generic and species diversity among Cetaceobothridius, Priapocephalus, Prosthecocotyle, Strobilocephalus, Tetrabothrius, and Trigonocotyle that constitute the tetrabothriidean fauna of odontocetes; species …

Revealing Cryptic Lineage Diversity In The Persian Gulf And Oman Sea Groupers (Perciformes: Epinephelidae): Phylogenetic And Species Delimitation Insights, Ehsan Damadi, Faezeh Yazdani Moghaddam, Masoumeh Gholipour Cheshm Gilak, Mehdi Ghanbarifardi

Turkish Journal of Zoology

Groupers (Epinephelidae) are a taxon of great commercial interest due to their large body size and high market value, and are also an important ecological species for biodiversity conservation in coral reef ecosystems. Despite their importance, phenotypic convergence among species generally leads to incorrect taxonomic identification, an issue enhanced by molecular studies revealing the presence of a high cryptic diversity and complicating conventional systematic frameworks. Herein, grouper species diversity in the ecologically heterogeneous Persian Gulf and Oman Sea was investigated to resolve taxonomic ambiguities and assess patterns of cryptic diversity. Mitochondrial COI gene sequencing was used in conjunction with integrative …

Genomic Investigation Of Population Structure In A Secretive, Semi‐Fossorial Snake (Colubridae: Tropidoclonion Lineatum) Across The Great Plains, Taylor Probst, Cameron D. Siler, Drew R. Davis

School of Integrative Biological & Chemical Sciences Faculty Publications

With advances in genomic technologies, it has become increasingly feasible to generate large numbers of loci to address population genetic and phylogeographic questions. Nevertheless, many widespread and relatively abundant species remain unsampled using molecular approaches. The lined snake ( Tropidoclonion lineatum ), a semi‐fossorial snake distributed across the Great Plains, is one such example. Despite the historical recognition of multiple subspecies based on noted variation in morphological characters, no formal molecular investigation of population structure has been conducted to date due to a paucity of vouchered genetic samples. Here, we present the first genomic assessment of range‐wide population structure in …

Determining The Feasibility Of A Habituation Assessment In Managed Red Wolves, Emily C. Lynch, Joseph W. Hinton, Jennifer B. Nagashima, Curtis Malott, Natalie J. Johnson, Emily Haering, Robin Petersen, Allison Johnson, Julie K. Young

Wildland Resources Faculty Publications

For species extirpated from the wild, ex situ breeding programs are essential for providing the individuals necessary for re-establishing wild populations through reintroductions. However, repeated exposure to humans under managed care may reduce wariness and alter behavioral responses in ways that are maladaptive after release. Although some pre-release behaviors reflect natural responses essential for survival and reproduction, others may result from habituation to humans and increase the risk of conflict, recapture, or mortality following translocation. These risks underscore the need for behavioral assessments to help identify appropriate candidates for release. However, because the assessments themselves require some exposure to humans, …

Effects Of Intensive Exercise On The Blood Chemistry Of Fighting Bulls In Southern Thailand, Siriwat Wasiksiri, Pratthana Yongsakulchai, Wichaya Thongtako, Paradorn Muangnil, Teepakorn Adulkasem

The Thai Journal of Veterinary Medicine

Bullfighting is a cultural activity in southern Thailand. Bulls walk and undergo intensive exercise before competition. In the arena, winners are determined by their opponents' surrender, so bulls do not die after fighting. However, there are very few studies on organ injuries in living bulls during these activities. This study compared the effects of walking and intensive exercise on complete blood count (CBC) and blood chemistry. Blood parameters of 14 Thai fighting bulls aged over 6 years, regularly trained for walking and intensive exercise, were measured and analyzed using a paired t-test or Wilcoxon signed-rank test. Eosinophils decreased significantly after …

A New Species Of Liocheles Sundevall, 1833 (Scorpiones: Hormuridae) From The Western Himalayas, Virender К. Bhardwaj, Sunil Katal, H. T. Lalremsanga, Zeeshan A. Mirza

Euscorpius

Sampling in the Western Himalayas of India led to the discovery of a population of the genus Liocheles Sundevall, 1833, that differes from all Indian congeners. Molecular and morphological data confirmed the distinctiveness of the population, which is here described as a new species. The new species is morphologically similar to L. longimanus (Werner, 1939), from which it differs in the arrangement of trichobothria on external patella and structure of the hemispermatophore. A preliminary molecular phylogeny of the family Hormuridae based on the mitochondrial cytochrome oxidase I gene is presented.

Effects Of Human-Animal Interaction On Positive Youth Development: A Replication Study, Allison Pachunka, Jay Jeffries, Lisa Karr, Lena Luck, Bryan A. Reiling, Douglas H. Schultz, Jeffrey R. Stevens

People and Animals: The International Journal of Research and Practice

Interacting with animals can improve health and well-being across the lifespan. Some programs such as 4-H and FFA center around youth interacting with animals, potentially enhancing youth development. Mueller (2014) investigated whether these interactions and attitudes about animals influenced measures of positive youth development. The aim of our studies was to replicate Mueller’s methods and extend her work by evaluating whether membership in animal-focused youth programs moderate associations between interactions, attitudes, and positive youth development. We did not find strong relationships among human–animal inter-action and positive youth development, which failed to replicate Mueller’s findings. However, we did find relationships between …
