Integrating Resource Selection Into Spatial Capture-Recapture Models For Large Carnivores, K. M. Proffitt, Joshua F. Goldberg, Mark Hebblewhite, R. Russell, B. S. Jimenez, H. S. Robinson, K. Pilgrim, M. K. Schwartz

Wildlife Biology Faculty Publications

Wildlife managers need reliable methods to estimate large carnivore densities and population trends; yet large carnivores are elusive, difficult to detect, and occur at low densities making traditional approaches intractable. Recent advances in spatial capture-recapture (SCR) models have provided new approaches for monitoring trends in wildlife abundance and these methods are particularly applicable to large carnivores. We applied SCR models in a Bayesian framework to estimate mountain lion densities in the Bitterroot Mountains of west central Montana. We incorporate an existing resource selection function (RSF) as a density co-variate to account for heterogeneity in habitat use across the study area …

Gene Loss, Adaptive Evolution And The Co-Evolution Of Plumage Coloration Genes With Opsins In Birds, Rui Borges, Imran Khan, Warren E. Johnson, M. Thomas P. Gilbert, Guojie Zhang, Erich D. Jarvis, Stephen J. O'Brien, Agostinho Antunes

Biology Faculty Articles

Background: The wide range of complex photic systems observed in birds exemplifies one of their key evolutionary adaptions, a well-developed visual system. However, genomic approaches have yet to be used to disentangle the evolutionary mechanisms that govern evolution of avian visual systems.

Results: We performed comparative genomic analyses across 48 avian genomes that span extant bird phylogenetic diversity to assess evolutionary changes in the 17 representatives of the opsin gene family and five plumage coloration genes. Our analyses suggest modern birds have maintained a repertoire of up to 15 opsins. Synteny analyses indicate that PARA and PARIE pineal …

Using An Agent-Based Model To Study The Effect Of Reproductive Skew On Mongoose Populations, Stacy Lee Mowry

Theses and Dissertations

Reproductive skew is the name given to the unequal partitioning of breeding

within social groups. Within these groups a mating hierarchy emerges wherein one dominant mating pair holds an unproportional majority of the group's reproductive benefit, while other members mate infrequently, yet allocate energy and resources toward the offspring of the dominant group members. In this paper, we use an agent-based model, which mimics dwarf and banded mongoose populations, to investigate how reproductive skew aftects the speed natural selection, and thus how reproductive skew affects fitness. The results of the model show that due to the geometric structure of skewed …

Esperamos convencer a los lectores que los métodos y aproximaciones del libro no son solo para los matemáticos, estadísticos y programadores de computadoras, sino que de hecho son herramientas esenciales para practicar la conservación en el …

The Examination Of Enrichment Using Space And Food For African Elephants (Loxodonta Africana) At The San Diego Zoo Safari Park, Charlotte Hacker

Masters Theses & Specialist Projects

Concern for elephant welfare in zoological facilities has prompted a number of exhibit and management modifications, including those involving enrichment. Knowledge of how these changes impact measures of health and wellbeing, such as elephant movement and behavior, is crucial as the effects of multiple enrichment types and their interactions are largely understudied. The present study used observations and GPS unit collected data to determine the effects of space and food on the walking distance and behavior of thirteen African elephants, whose dominance structure was ascertained by the handlers at the San Diego Zoo Safari Park (SDZSP). This facility has two …

First Nesting Record And Status Review Of The Glossy Ibis In Nebraska, Joel G. Jorgensen, W. Ross Silcock

Nebraska Bird Review

Glossy Ibis (Plegadis falcinellus) is believed to be a recent colonist from the Old World whose numbers have increased and range has expanded in North America over the past two centuries (Patten and Lasley 2000). Glossy Ibis range expansion has been described as involving periods of relative stability followed by periods of rapid increase (Patten and Lasley 2000). Prior to the 1980s, Glossy Ibis were primarily found in the southeastern United States and along the Atlantic Coast (Patten and Lasley 2000). In the mid to late 1980s, Glossy Ibis began to rapidly increase and expand into Texas. By …

Summer Field Report, June–July 2015, W. Ross Silcock

Nebraska Bird Review

This summer was very wet over most of the state. Breeding Bird Survey operators noted impassible roads, especially in the western Sandhills. The benefits to water birds in the Rainwater Basin were obvious, however, with notable breeding records for Ruddy Duck and White-faced Ibis, as well as the first documented breeding in the state of Glossy Ibis, and the first Rainwater Basin breeding for Double-crested Cormorant and third for Eared Grebe.

Additional notable breeding records were led by Osprey; after 7 years of trying at various locations, success came with a bang, as at least 3 nests successfully fledged young, …

Spreading Holiday Spirit And Northwestern Salamanders, Ambystoma Gracile (Baird 1859) (Caudata: Ambystomatidae), Across The Usa, Michael R. Rochford, Jeffrey M. Lemm, Kenneth Krysko, Louis A. Somma, Robert W. Hansen, Frank J. Mazzotti

Papers in Herpetology

Introduced species of amphibians and reptiles are of growing conservation concern (Bury and Luckenbach 1976; Krysko et al. 2011; Meshaka 2011). Unintentional introductions result largely from individuals escaping from enclosures or hitch-hiking in cargo or on vehicles, whereas intentional introductions occur primarily because a species is perceived to be of value to humans or from deliberately releasing sick or unwanted animals, including pets (Kraus 2009; Krysko et al. 2011). In Florida, most known introductions are directly related to the pet trade, but about 12% are related to the cargo pathway (Krysko et al. 2011). In this paper, we report the …

Taxonomy Of The Bitentaculate Cirratulidae (Polychaeta), Stacy A. Tewari

Graduate Masters Theses

The bitentaculate cirratulid polychaetes are an important faunal element of both near shore and deep-sea benthic faunal communities. The true diversity of the family is currently unknown due to a large number of undescribed species and erroneously applied “cospmopolitan” names being applied to local species. Cirratulids have been misidentified even in the local waters near the University of Massachusetts Boston. The current study presents six new species from North America. Caulleriella venefica, Chaetozone anasimus, Chaetozone diodonta, and Chaetozone hystricosus are described from Boston Harbor and Massachusetts Bay where only two species had previously been reported. Aphelochaeta bullata …

Responses Of Primate Frontal Cortex Neurons During Natural Vocal Communication, Cory T. Miller, A. Wren Thomas, Samuel U. Nummela, Lisa A. De La Mothe

Psychological Sciences and Counseling Faculty Research

The role of primate frontal cortex in vocal communication and its significance in language evolution have a controversial history. While evidence indicates that vocalization processing occurs in ventrolateral prefrontal cortex neurons, vocal-motor activity has been conjectured to be primarily subcortical and suggestive of a distinctly different neural architecture from humans. Direct evidence of neural activity during natural vocal communication is limited, as previous studies were performed in chair-restrained animals. Here we recorded the activity of single neurons across multiple regions of prefrontal and premotor cortex while freely moving marmosets engaged in a natural vocal behavior known as antiphonal calling. Our …

Seasonal Dynamics And Micro-Climatic Preference Of Two Alpine Endemic Hypogean Beetles, Stefano Mammola, Elena Piano, Pier Mauro Giachino, Marco Isaia

International Journal of Speleology

Hypogean beetles generally live in stable environments, characterized by constant temperature and high relative humidity. Changes in the underground microclimatic conditions generally induce local migrations of the beetles through the hypogean environment in search of suitable microhabitats. We studied the seasonal dynamics and the micro-climatic preference of two Alpine endemic hypogean beetles - Sphodropsis ghilianii (Coleoptera, Carabidae) and Dellabeffaella roccae (Coleoptera, Cholevidae) - in the hypogean complex of Pugnetto (Graian Alps, Italy). We surveyed the two species for one year, using baited pitfall traps and measuring temperature and humidity along the two main caves. We used logistic regression mixed models …

In Vitro And In Vivo Evaluation Of Infestation Deterrents Against Lice, Kyong-Sup Yoon, Jennifer K. Ketzis, Samuel W. Andrewes, Christopher S. Wu, Kris Honraet, Dorien Staljanssens, Bart Rossel, J Marshall Clark

SIUE Faculty Research, Scholarship, and Creative Activity

The human head louse is a cosmopolitan ectoparasite and frequently infests many people, particularly school-age children. Due to widespread pyrethroid resistance and the lack of efficient resistance management, there has been a considerable interest in the protection of uninfested people and prevention of reinfestation by disrupting lice transfer. In this study, two nonclinical model systems (in vitro and in vivo) were used to determine the efficacy of the infestation deterrents, Elimax lotion and Elimax shampoo, against human head lice or poultry chewing lice, respectively. With in vitro assessments, female head lice exhibited significantly higher avoidance responses to hair tufts treated …

Nou Spring Field Days And Annual Meeting, Valentine, May 15–17, 2015, Janis Paseka

Nebraska Bird Review

The annual meeting of the Nebraska Ornithologists' Union was held in Valentine May 15–17, 2015, and ably organized by Dave Heidt and Betty Grenon. Although muddy roads from a Friday night storm prevented travel to several planned field trip destinations on Saturday and rain cut short field trips on Sunday morning, the 58 attendees were able to locate and identify 180 species. Most of the birding took place in Cherry County, and many birders commented happily on the good number of species they were able to add to their Cherry Co. lists.

On Friday evening Wayne Mollhoff told the group …
