A New Species Of Chiasmocleis (Microhylidae, Gastrophryninae) From The Atlantic Forest Of Espírito Santo State, Brazil, João Filipe Tonini, Maruicio Forlani, Rafael O. De Sá Jul 2014

A New Species Of Chiasmocleis (Microhylidae, Gastrophryninae) From The Atlantic Forest Of Espírito Santo State, Brazil, João Filipe Tonini, Maruicio Forlani, Rafael O. De Sá

Biology Faculty Publications

Among Neotropical microhylids, the genus Chiasmocleis is exceptionally diverse. Most species ofChiasmocleis were described in recent years based on external morphology, but recent studies using molecular data did not support the monophyly of the species groups clustered based on feet webbing. Furthermore, a phylogeographic study of C. lacrimae estimated high genetic divergence and low gene flow among populations across small geographic ranges. Increasing the molecular and geographic sampling, and incorporating morphological data, we identified new cryptic species. Herein, we used novel genetic and morphological data to describe a new species of Chiasmocleis.


The Dynamic Proliferation Of Cansines Mirrors The Complex Evolution Of Feliforms, Kathryn B. Walters-Conte, Diana L. E. Johnson, Warren E. Johnson, Stephen J. O'Brien, Jill Pecon-Slattery Jun 2014

The Dynamic Proliferation Of Cansines Mirrors The Complex Evolution Of Feliforms, Kathryn B. Walters-Conte, Diana L. E. Johnson, Warren E. Johnson, Stephen J. O'Brien, Jill Pecon-Slattery

Biology Faculty Articles

Background: Repetitive short interspersed elements (SINEs) are retrotransposons ubiquitous in mammalian genomes and are highly informative markers to identify species and phylogenetic associations. Of these, SINEs unique to the order Carnivora (CanSINEs) yield novel insights on genome evolution in domestic dogs and cats, but less is known about their role in related carnivores. In particular, genome-wide assessment of CanSINE evolution has yet to be completed across the Feliformia (cat-like) suborder of Carnivora. Within Feliformia, the cat family Felidae is composed of 37 species and numerous subspecies organized into eight monophyletic lineages that likely arose 10 million years ago. Using …


New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook Jun 2014

New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The genus Ctenomys Blainville 1826 is one of the most diverse of South American hystricognath rodents. Currently, nine species of tuco-tucos are reported from Bolivia, four at elevations above 2,000 m and five inhabiting the lowlands (< 1,000 m). In the present paper, morphology, karyology, and phylogenetic analyses of DNA sequences for a mitochondrial locus were used to assess the taxonomic status of specimens of Ctenomys from localities beyond the previously known ranges of these rodents in the departments of Chuquisaca, Cochabamba, Santa Cruz, and Tarija. Based on these analyses, we describe four new species in the genus Ctenomys, all apparently endemic to the country. In addition, we place Ctenomys goodfellowi Thomas 1921 in synonymy under C. boliviensis Waterhouse 1848 and confirm the presence of C. nattereri …


Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis Jun 2014

Coral-Fish Dynamics And Interactions: A Case Study Of Grand Cayman, Eileen Shea Davis

Lawrence University Honors Projects

To better understand the ecological interactions of coral reefs, it is important to understand the mechanisms that control the distribution and abundance of reef-building corals as well as the mechanisms that control the diversity and abundance of the fish community that inhabits these reef habitats. The purpose of this study was to identify specific coral-fish interactions among the reefs of Grand Cayman in order to gain insight into the biological effects of fish on the assemblage of hard corals. Using data collected by the Lawrence University Marine Program (LUMP), a number of exploratory statistical analyses were run in order to …


Behaviors That Predict Personality Components In Adult Free-Ranging Tibetan Macaques (Macaca Thibetana), Alexander J. Pritchard, Lori K. Sheeran, Kara I. Gabriel, Jin-Hua Li, Ronald S. Wagner Jun 2014

Behaviors That Predict Personality Components In Adult Free-Ranging Tibetan Macaques (Macaca Thibetana), Alexander J. Pritchard, Lori K. Sheeran, Kara I. Gabriel, Jin-Hua Li, Ronald S. Wagner

Anthropology and Museum Studies Faculty Scholarship

To further the potential for applied personality studies, we present a methodology for assessing personality in nonhuman animals without a priori assumptions, using behavioral measures to discriminate personality survey results. Our study group consisted of 12 free-ranging, provisioned, adult Tibetan macaques (Macaca thibetana) at the Valley of the Wild Monkeys, China. We asked familiar Chinese park guards and scientists to rate each of the 12 macaques using 27-item personality surveys. We also recorded behavioral observations (> 100 hrs) from August–September, 2012. The personality surveys showed reliability in 22 of the items that were then utilized in a principal component analysis …

Western Massasauga (Sistrurus Tergeminus): Species Conservation Assessment, Melissa J. Panella, Brent D. Johnson

Nebraska Game and Parks Commission: Publications

The primary goal in development of at-risk species conservation assessments is to compile biological and ecological information that may assist conservation practitioners in making decisions regarding the conservation of species of interest. The Nebraska Natural Legacy Project recognizes the Western Massasauga (Sistrurus tergeminus) as a Tier I at-risk species. Provided are some general management recommendations regarding Western Massasaugas. Conservation practitioners will need to use professional judgment to make specific management decisions based on objectives, location, and a multitude of variables. This resource was designed to share available knowledge of this at-risk species that will aid in the decision-making process or …


2014 Nou/Iou Joint Meeting In Bellevue, Clem Klaphake Jun 2014

2014 Nou/Iou Joint Meeting In Bellevue, Clem Klaphake

Nebraska Bird Review

The May 16–18 combined meeting of the Nebraska Ornithologists' Union and the Iowa Ornithologists' Union at Fontenelle Forest Nature Center in Bellevue, Nebraska, was a gigantic success. Over 160 birders from Nebraska, Iowa, and 6 other states attended the 3 day event. Everyone I talked to, from novice to expert, was more than delighted with all of the activities scheduled for this event.

Our Friday evening speaker, Ty Smedes, had some wonderful photos, especially of warblers, and I heard nothing but positive comments about his program from the attendees. On Saturday afternoon Jerry Toll talked about his experiences banding Red-tailed …


What Are Blue Ross's Geese?, Paul A. Johnsgard Jun 2014

What Are Blue Ross's Geese?, Paul A. Johnsgard

Nebraska Bird Review

The existence of blue morph ("phase") Ross's Geese (Chen rossii) was first well documented by McLandress & McLandress (1979). They reported on several blue-morph birds seen and collected in California and Canada that morphologically appeared to be pure Ross's Geese and on others with intermediate traits that appeared to be hybrids with Lesser Snow Geese (Chen caerulescens caerulescens). They also noted that in the California wintering grounds counts held during 1976–77 there were only 3 blue morphs (0.008 percent) among the 38,825 Ross's Geese counted. At that time, only 0.02 percent of the Lesser Snow Geese …


Double-Crested Cormorant And American White Pelican Abundance At Sandhills Lakes During Fall Migration, Lauren R. Dinan, Joel G. Jorgensen Jun 2014

Double-Crested Cormorant And American White Pelican Abundance At Sandhills Lakes During Fall Migration, Lauren R. Dinan, Joel G. Jorgensen

Nebraska Bird Review

Double-crested Cormorants (DCCO, Phalacrocorax auritus) and American White Pelicans (AWPE, Pelecanus erythrorhynchos) are migratory piscivorous birds that breed in North America. Both species are abundant spring and fall migrants in Nebraska. DCCOs are also common, albeit local, breeders in northwestern Nebraska (Sharpe et al. 2001 ). DCCO and AWPE numbers have increased throughout their range in recent decades (U.S. Fish and Wildlife Service [USFWS] 2003, Sauer et al. 2013). Both species, but primarily DCCOs, have become increasingly controversial because of increased numbers and also because their principal food source is fish, a resource humans value. Concentrations of DCCOs, and to …

Spring Field Report, March 2014 To May 2014, W. Ross Silcock

Nebraska Bird Review

This spring period was generally uneventful for most species groups, but there were two major influxes in the east that were likely unprecedented in the memories of most Nebraska ornithologists. First was a major influx of gulls of 10 species at Carter Lake and N.P. Dodge Park in Omaha, including good numbers of California and Thayer's Gulls, as well as Iceland, and most surprisingly, a Glaucous-winged Gull. A bit later in the season was a strong influx of the rarer migrant warblers, such as Golden-winged, Blue-winged, Hooded, Cape May, Bay-breasted, and Black-throated Blue. For spice there was a Worm-eating Warbler …

Prioritizing Non-Marine Invertebrate Taxa For Red Listing, Neil Cumberlidge, Justin Gerlach Phd Jun 2014

Prioritizing Non-Marine Invertebrate Taxa For Red Listing, Neil Cumberlidge, Justin Gerlach Phd

Journal Articles

The IUCN Red List of threatened species is biased towards vertebrate animals, a major limitation on its utility for overall biodiversity assessment. There is a need to increase the representation of invertebrates (currently 21 % of species assessed on the List;\1 % of all invertebrates). A prioritisation system of terrestrial and freshwater groups is presented here, categorising taxa by species richness, assessment practicality, value for human land use and bioindication, and potential to act as conservation flagships. 25 major taxonomic groupings were identified as priorities, including the Annelida, Arthropoda, Mollusca and Onycophora. Of these, the high-level taxa that emerge as …


The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá Jun 2014

The Neotropical Genus Austrolebias: An Emerging Model Of Annual Killifishes, Nibia Berois, María J. Arezo, Rafael O. De Sá

Biology Faculty Publications

Annual fishes are found in both Africa and South America occupying ephemeral ponds that dried seasonally. Neotropical annual fishes are members of the family Rivulidae that consist of both annual and non-annual fishes. Annual species are characterized by a prolonged embryonic development and a relatively short adult life.

Males and females show striking sexual dimorphisms, complex courtship, and mating behaviors. The prolonged embryonic stage has several traits including embryos that are resistant to desiccation and undergo up to three reversible developmental arrests until hatching. These unique developmental adaptations are closely related to the annual fish life cycle and are the …


Zutrition: Analyzing And Evaluating Diets Fed To Captive Mammals At Capron Park Zoo, Briell M. Dzierga May 2014

Zutrition: Analyzing And Evaluating Diets Fed To Captive Mammals At Capron Park Zoo, Briell M. Dzierga

Senior Honors Projects

Zoos provide both experiential and educational opportunities for the general public to learn about animals found in a variety of habitats around the world. A successful zoo must provide a safe and enjoyable environment for the visitors, in addition to the species living within the enclosures. Animal husbandry and welfare are crucial aspects to which close attention must be paid, and zoos have a responsibility to attempt to approximate the captive species’ natural habitats and life histories. An essential part of maintaining a captive zoo animal’s health and wellbeing is providing the animal with an appropriate diet. In addition to …


Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis May 2014

Level Of Uv-B Radiation Influences The Effects Of Glyphosate-Based Herbicide On Fitness Of The Spotted Salamander, Nicholas A. Levis

Masters Theses & Specialist Projects

Numerous causes have been implicated in contributing to amphibian population declines since the 1980's, with habitat modification, ultraviolet radiation (UV-B) and environmental contaminants (such as glyphosate-based herbicide) being among the most common. This study identifies the effects of a generic glyphosate-based herbicide (GLY- 4 Plus) on mortality, immune function, body condition, and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy (i.e. greater UV-B exposure) may confer fitness benefits. In …


Feedforward And Feedback Projections Of Caudal Belt And Parabelt Areas Of Auditory Cortex: Refining The Hierarchical Model, Troy A. Hackett, Lisa A. De La Mothe, Corrie R. Camalier, Arnaud Falchier, Peter Lakatos, Yoshinao Kajikawa, Charles E. Schroeder Apr 2014

Feedforward And Feedback Projections Of Caudal Belt And Parabelt Areas Of Auditory Cortex: Refining The Hierarchical Model, Troy A. Hackett, Lisa A. De La Mothe, Corrie R. Camalier, Arnaud Falchier, Peter Lakatos, Yoshinao Kajikawa, Charles E. Schroeder

Psychology Faculty Research

Our working model of the primate auditory cortex recognizes three major regions (core, belt, parabelt), subdivided into thirteen areas. The connections between areas are topographically ordered in a manner consistent with information flow along two major anatomical axes: core-belt-parabelt and caudal-rostral. Remarkably, most of the connections supporting this model were revealed using retrograde tracing techniques. Little is known about laminar circuitry, as anterograde tracing of axon terminations has rarely been used. The purpose of the present study was to examine the laminar projections of three areas of auditory cortex, pursuant to analysis of all areas. The selected areas were: middle …

Scott L. Gardner Publications

Abstract

Plagioscion squamosissimus (Heckel 1840), a fish endemic to the Amazon Basin and commonly known as the “silver croaker”, plays an important role in the ecology and economy of Pará State, Brazil. Knowledge of host-parasite relationships is important to understanding the role of parasites in the control of natural host populations. This work describes histopathological aspects caused by several common intestinal parasites found during a helminthological survey of fish in northern Brazil. We observed a high prevalence of helminth infection, especially by J3 nematode juveniles of the family Anisakidae and metacestodes of the family Protocephalidae (both with 100% prevalence). An …

Multilocus Coalescent Analyses Reveal The Demographic History Of Mouse Lemur Sister Species., Christopher Blair, Kellie L. Heckman, Amy L. Russell, Anne D. Yoder

Publications and Research

Debate continues as to whether allopatric speciation or peripatric speciation through a founder effect is the predominant force driving evolution in vertebrates. The mouse lemurs of Madagascar are a system in which evolution has generated a large number of species over a relatively recent time frame. Here, we examine speciation patterns in a pair of sister species of mouse lemur, Microcebus murinus and M. griseorufus. These two species have ranges that are disparately proportioned in size, with M. murinus showing a much more extensive range that marginally overlaps that of M. griseorufus. Given that these two species are …

Hymenolepis Robertrauschi N. Sp. From Grasshopper Mice Onychomys Spp. In New Mexico And Nebraska, U.S.A., Scott Lyell Gardner, Brent A. Luedders, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola …

Gower, Davide Pisani, Roman Kassahun, Fikirte Gebresenbet, Michele Menegon, Abebe A. Mengistu, Samy A. Saber, Rafael O. De Sá, Mark Wilkinson, Simon P. Loader

Biology Faculty Publications

Background: The phylogenetic relationships of many taxa remain poorly known because of a lack of appropriate data and/or analyses. Despite substantial recent advances, amphibian phylogeny remains poorly resolved in many instances. The phylogenetic relationships of the Ethiopian endemic monotypic genus Ericabatrachus has been addressed thus far only with phenotypic data and remains contentious.

Results: We obtained fresh samples of the now rare and Critically Endangered Ericabatrachus baleensis and generated DNA sequences for two mitochondrial and four nuclear genes. Analyses of these new data using de novo and constrained-tree phylogenetic reconstructions strongly support a close relationship between Ericabatrachus and …

Winter Field Report, December 2013 To February 2014, W. Ross Silcock

Nebraska Bird Review

This was a low-key winter season in terms of reportable phenomena of any significance, although three species provided food for thought: high numbers of Rough-legged Hawks, the possibility of breeding Northern Saw-whet Owls in the cedar canyons of Lincoln Co, and the possible impending demise of Black-billed Magpie over most of the state. Also noteworthy is the continuing increase in midwinter reports of a wide range of species that previously have accounted for very few such records. Notable in this respect are waterfowl, mimids, non-oriole icterids, and sparrows; a Say's Phoebe in December was the most surprising record in this …

2013 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fifteen counts were held during the 2013–2014 season. Following a cold snap in early December, the weather was seasonable and mostly dry, but with very limited open water in most circles. An example of the consequences of this can be seen in the Branched Oak–Seward count tally. Although this count has a history of being very productive for water-related birds in most years, only 3 species were found this year: Canada Goose (16), Mallard (2) and Belted Kingfisher (1). The total species count in all the counts was 135, four less than the past two years and historically ranking sixth …

A Survey Of The Ratio Of Melanistic To Gray Squirrels (Sciurus Carolinensis) On Five Midwestern College Campuses, Molly Koleczek Mar 2014

A Survey Of The Ratio Of Melanistic To Gray Squirrels (Sciurus Carolinensis) On Five Midwestern College Campuses, Molly Koleczek

Honors Program Projects

This experiment was an observational field study on 5 college campuses across western Indiana and western Illinois. The purpose of this experiment was to find the ratio of melanistic to gray squirrels on each campus and see if the ratio changed geographically. Gray squirrels (Sciurus carolinensis) have melanistic color variants in their populations that have not been documented across their distribution in the United States. Melanistic variants were introduced in the eastern United States and seem to be moving westward. Data was collected for all 4 seasons for Olivet Nazarene University, St. Joseph’s College and Illinois State University. …
