2023 (35th) Report Of The Nou Records Committee, Mark A. Brogie

Nebraska Bird Review

The functions and methods of the Nebraska Ornithologists’ Union Records Committee (NOURC) are described in its bylaws (NOURC 2010). The committee’s purpose is to provide a procedure for documenting unusual bird sightings and to establish a list of all documented birds for Nebraska. Species for which the NOURC seeks documentation (NOURC Review List) can be found at the NOU website https://noubirds.org/Birds/ReviewList.aspx. Starting in 2020, the NOURC decided to deal mainly with those species deemed as Accidental on the “Official List of the Birds of Nebraska”. Casual species and out-of- range species are now summarized in the “Seasonal Reports” of the …

Summer Field Report, June–July 2024, W. Ross Silcock

Nebraska Bird Review

This was an intriguing summer in several ways. I am far from being a knowledgeable ecologist, but, like most of us, as a layman I wonder whether and how weather affects birds, and if and how local weather is reflecting the conventional wisdom of climate change. Climate change seems increasingly to be expressed as various extreme or rapidly changing weather events that have differing effects on vegetation and consequently insect and larger prey populations. Every species responds differently it seems, depending on its biological needs, but food supply is the most important issue for birds. It is tempting to assign …

Methodologies For Dry Fixation And Taxidermy Of Education-Oriented Scorpion Specimens, Victoria Tang

Euscorpius

Scorpions hold a renowned status as iconic creatures across numerous cultures in the world. Traditionally preserved as desiccated specimens for educational purposes, they have been exhibited in museums and pedagogic collections, serving as concrete epistemological conduits for public education on biodiversity. However, these specimens frequently lack meticulous organization, potentially misrepresenting the animals’ ethological characteristics. This brief article aims to offer paradigmatic guidance for taxidermy of scorpions, ensuring a more accurate depiction of their in vivo habitus, achievable through the use of readily obtainable tools and undemanding techniques.

Terrestrial Salinization Impacts On Growth And Behavior Of A Common Detritivore Armadillidium Vulgare (Isopoda), Danielle Harmoney Orcutt

Master's Theses

Climate change and human activities are changing the nutritional landscape by increasing the availability of some essential elements and decreasing others. Sodium (Na) is an essential element in heterotrophs, which is required for water regulation, nerve function, and muscle function. Heterotrophs can acquire Na through diet and environment, often experiencing limited availability of Na due to plants concentrating Na 10-100 times less than heterotrophs need. The Sodium Subsidy-Stress (SSS) hypothesis posits that organismal performance follows a hump-shaped curve of a physiological response, where Na acts as a subsidy, increasing organismal performance such as growth until an optimal threshold is reached, …

Three New Species Of Genus Scorpiops Peters, 1861 From Tibet, China (Scorpiones: Scorpiopidae), With Implications For The Diagnostic Values Of Qualitative Characters, Victoria Tang, Kaichen Ouyang, Zhenbang Liu, František Šťáhlavský

Euscorpius

Three new species of genus Scorpiops Peters, 1861 are described from Tibet Autonomous Region, China. S. deshpandei sp. n. is described based on an adult male and an immature pair collected from Mêdog County, Nyingchi, with additional molecular evidence substantiating its validity against S. longimanus Pocock, 1893. S. kovariki sp. n. is featured by a single adult female from Zayü. This species is only weakly supported by its genetic distance from S. jendeki Kovařík, 1994, but empirical understanding of the morphological variation in Scorpiops species motivated us to consider them as distinct. S. matthewi sp. n. is based on …

Euscorpius Gulhanimae Sp. N. From The Konya Province, Turkey (Scorpiones: Euscorpiidae), Ersen A. Yağmur

Also, Scorpio jordanensis sp. n. and S. wahbehi sp. n. are described. Detailed …

The Effects Of People, Time Of Day, And Season On Affiliative And Stereotypic Behaviors In Captive Rhinoptera Bonasus And Other Rays Across Two Human-Interactive Enclosures, Wren C. A. Newman

Theses and Dissertations

Cownose rays (Rhinoptera bonasus) are among the most common species found in aquaria, yet the impact of touch enclosures on their welfare remains largely unknown. While research on animal-visitor interactions has produced mixed results for other species, the lack of studies focusing on fish welfare poses a risk of overlooking potential welfare concerns. Therefore, we aimed to establish a baseline for cownose rays regarding stereotypic behaviors, sociality, and activity in captivity, and to examine the influence of human interaction on these behaviors. We collected over 700 hours of footage from two enclosures at Adventure Aquarium in Camden, NJ …

Sex Differences In The Diets Of Forest-Dwelling Baboons (Papio Anubis), Kara Hartunian

Theses and Dissertations

The ability to eat and switch between many food sources is an adaptative feeding strategy utilized for meeting nutritional needs across different environments, seasons, and physiological conditions. Baboons (genus Papio) excel at both dietary flexibility and foraging selectively, and consequently have one of the most widespread geographic distributions in the Order. To further expand to our understanding of baboon feeding ecology, I analyzed foraging activity and the nutritional characteristics of the diets of the relatively understudied rainforest baboons (Papio anubis) living in Kibale National Park, Uganda. I also investigated if there are differences in food type choice …

Maternal And Other Social Influences On Signature Whistle Structure Of A Captive Group Of Bottlenose Dolphins (Tursiops Truncatus), Riley Synan

Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) are social animals that use acoustics as a major method of communicating across a marine environment. They also live in fission-fusion groups and thus interact with many conspecifics over a lifetime. Individual dolphins have a signature whistle that functions as an identity call and serves to maintain group cohesion in murky waters or during reconciliation. Dolphins exhibit vocal learning and the signature whistle of a calf may be modeled after the whistle of their mother or another individual in the pod as they develop. Mother-calf pairs or other related animals sometimes have similar whistle types. Some …

Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan

Theses and Dissertations

Many studies have been conducted using a training paradigm based on the research of Pryor et al. (1969) wherein the participants are trained on the abstract concept: do something different. This paradigm challenges working memory and requires the participants to respond with a behavior, either previously trained or novel, which has not yet been offered within the session. The work of Braslau-Schneck (1994) expanded this concept and demonstrated the ability of dolphins to successfully complete this task in synchronized pairs, though the method of accomplishing this task remained unclear. The present research was conducted as part of a broader …

Avian Communities Monitored Along A Successional Chronosequence In Bottomland Hardwood Forests In The Lower Mississippi Alluvial Valley, Eamonn Alasdair Thurmond

Electronic Theses and Dissertations

Bottomland hardwood forests in the Lower Mississippi Alluvial Valley have been extensively reduced due to agriculture conversion and altered hydrology. Remnant forests have undergone further degradation from sources such as a lack of forest management, invasive species, and reduced regeneration of oaks (Quercus spp.). Recent restoration efforts of bottomland hardwood forests have focused on implementing wildlife forestry practices that prioritize restoring wildlife habitat while retaining profitable timber harvests. In this study I surveyed bird communities in bottomland hardwood forests in the Lower Mississippi Alluvial Valley along a successional chronosequence. Birds were sampled using automated recording units over 10 days …

Unraveling The Behavioral Ecology Of The Western Diamond-Backed Rattlesnake (Crotalus Atrox) Through The Lenses Of Personality, Predator-Prey Interactions, And Crypsis, Oceane Da Cunha

Open Access Theses & Dissertations

To thrive in an environment, individuals need to be able to forage efficiently and acquire mates. These resources are limited, and their acquisition depends upon the energy and time an individual chooses to allocate to each activity and the environmental conditions, leading to behavioral trade-offs. Different species, or even different individuals within the same population, respond to these trade-offs by employing contrasting strategies, leading to differential life-history outcomes. The overarching goal of this dissertation is to gain a better understanding of the trade-offs cryptic ambush mesopredators are facing using the western diamond-backed rattlesnake (Crotalus atrox) as a model species. Each …

Phylogenetic And Biogeographic Patterns Of Devonian Proetid Trilobites, Katherine Jane Jordan

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Ecological disruption events such as mass extinctions can result in the permanent alteration in clades and ecosystems. A pivotal time of change during the history of life on Earth can be seen in the Devonian Period. During this time, major transitions in marine and terrestrial system resulted in a different world at the end of the period in comparison to the beginning. One such group most heavily impacted were trilobites. Trilobites were reduced to one order by the end of the Devonian: Proetida. My dissertation focuses on phylogenetic, biogeographic, and paleocommunity patterns of this group, known as the last of …

Species Vary In Within-Species Variability, Jennifer Vonk

Animal Sentience

Owens et al. (2024) add to the growing voices stressing the importance of considering individual differences in animal welfare and conservation. I advocate for an additional emphasis on the importance of between species comparisons of the degree of individual variation in cognition and emotion within species. A better understanding of the factors predicting within-species variability will help conservationists target their efforts. Additionally, I caution against invoking circularity in using “behavioural traits” to predict related behaviours.

Populations Of The Stygobiotic Amphipod Palearcticarellus Pusillus (Martynov, 1930) Maintain Genetic Connectivity Between The Mountain Springs And The Deep Bottom Habitats Of Lake Teletskoye (Altai Mountains, Russia), Ivan Marin, Liubov Yanygina, Svetlana Ostroukhova, Dmitry Palatov

International Journal of Speleology

The diversity of underground fauna is often associated with the presence of karst areas, which have extensive underground cavities and connecting channels. Non-karst areas, however, make up a larger portion of the planet’ surface, and our understanding of the distribution and dispersal abilities of underground fauna in these areas currently remains limited. During a recent study of the diversity of stygobiotic crustaceans in the mountain streams of the Kurai Mountain Range (Altai, Russia), a small-sized species of crangonyctid amphipod, Palearcticarellus pusillus (Crustacea, Amphipoda, Crangonyctidae) was found in high-altitude springs. This species has been previously known only from deep-water habitats in …

Microplastic Accumulation In The Marsh Periwinkle (Littoraria Irrorata), Sarah Keaton, Hannah Lukhard, Eli Windy, Manar Hasan

DePaul Discoveries

Contamination of oceans by microplastics (mm) currently poses a major threat to aquatic and terrestrial ecosystems worldwide. Recent attention towards this issue has raised questions about the extent to which microplastics have accumulated in the environment, and has led to an increase in studies on the effects of microplastics in various organisms. However, levels of contamination in protected natural areas are still largely unexplored, yet can offer an important empirical perspective on the issue. In addition, little is known about the potential effects of microplastics on behavior in the field. This research was conducted within the protected ACE Basin National …

Turkish Journal of Zoology

As a sea turtle conservation area, Alas Purwo National Park (APNP) shows different patterns in the four species of turtles thathave nesting records, such as an increase in Olive Ridley Turtle (Lepidochelys olivacea), stability in Green Turtle (Chelonia mydas), anda decline in Hawksbill Turtle (Eretmochelys imbricata) and Leatherback Turtle (Dermochelys coriacea). During the survey, which lastedfrom January to July 2023, we discovered that each type of sea turtle preferred nesting sites at specific hypothetical stations, except forthe L. olivacea, which nested at all hypothetical stations along Pancur-Cungur Coast. We also discovered that it is highly encouragedto continue relocations that have …

Modeling Habitat Suitability And Current Distribution Of The Relicted Maghreb Magpie (Pica Mauritanica), Kamel Eddine Mederbal, Mohcen Menaa, Abdallah Aouadi, Lamia Boutabia, Lamia Bensaâd-Bendjedid, Khalladi Mederbal, Amira Bouderbala, Abderrahmane Chebli, Salah Telailia

Turkish Journal of Zoology

The Maghreb Magpie (Pica mauritanica) is an endemic bird to North Africa, encompassing Algeria, Morocco, and Tunisia. Unfortunately, its population is facing a significant decline primarily attributed to habitat loss and fragmentation resulting from urbanization and agricultural practices. Due to the lack of studies on habitat requirements of Pica mauritanica on a large scale, investigating the habitat preferences of this species and thereby understanding the potential threats, remains crucial for effective conservation strategies. We performed species distribution modeling (SDM), incorporating both occurrence records and predictor variables, to investigate the potentially suitable habitat and the factors influencing the distribution of the …

Limited Thermal Plasticity In High Mountain Tropical Water Bear, Juan Manuel Carvajalino-Fernández, Valentina Diaz-Galvis, Alan Dante Torres-Jaramillo

Turkish Journal of Zoology

Tardigrades, a phylum of microscopic organisms well known for their resistance to extreme conditions thanks to adaptations such as cryptobiosis, in which they are able to suspend their metabolism until more favorable conditions arise. These organisms are found in a wide range of environments, and high Andean mountains are not the exception, even though weather conditions are highly variable during the day, let alone a month. An experiment was thus conducted at 2600m in Bogotá, Colombia to evaluate the resistance of Macrobiotus sp. found on trees, three sets of fifteen tardigrades were exposed to 20 °C, 30 °C and 40 …

Artificial Light At Night On Nesting Beaches Of The Green Turtle, Chelonia Mydas, In The Eastern Mediterranean And Its Possible Effect On Populations, Noam Leader, Yaniv Levy, Oğuz Türkozan

Turkish Journal of Zoology

Artificial light associated with coastal development is becoming one of the major threats to coastal biodiversity. Sea turtles are coastal breeders, and it is well-known that hatchlings tend to move toward lighter objects on the beach, which prevents them from reaching the sea. It is, therefore, essential to identify the impact of artificial light at night (ALAN) on the nesting beaches. Here, we investigated ALAN levels using imagery from satellites at important green turtle (Chelonia mydas) nesting beaches in the Mediterranean. Mean August radiance levels at nesting beaches ranged from 0.00473 nW/cm2sr (Northern Cyprus-South Karpaz Beach) to 14.44 nW/cm2sr (Turkey …

Biostratigraphic Revision Of Esthonyx (Tillidontia, Mammalia) In The Contect Of Climate Change In The Lower Eocene Of The Bighorn Basin, Wyoming, John Colter Johnson

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Esthonyx is an early Eocene tillodont found in North America, Europe, and India. The genus was named by Edward Drinker (E. D.) Cope in 1874 based on specimens from the San Jose Formation in New Mexico. Since then, several species of Esthonyx have been described from North America alone. The best record of Esthonyx comes from the central Bighorn Basin (BHB) in Wyoming, where it appears in 220 localities in a 640 m-thick stratigraphic succession. Since the last summary of Esthonyx in the BHB, several hundred new specimens have been collected and curated at the Denver Museum of Nature and …

Identifying The Relative Abundance Of Cell-Cell Signaling Peptides During Mammalian Hibernation And Anesthetic Administration By Label-Free Peptidomics Analysis, Somayeh Mousavi

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Cell-cell signaling molecules known as neuropeptide and peptide hormones, distributed in both the central nervous system (CNS) and the peripheral nervous system (PNS), regulate a variety of physiological processes including body temperature, feeding, circadian rhythm, reproduction, energy homeostasis, and more. While a number of active neuropeptides structures with physiological functions have been discovered, advances in peptidomic mass spectrometry are enabling researchers to uncover novel, previously unknown, active neuropeptide structures with potential for bioactivities. Using liquid chromatography coupled with tandem mass spectrometry (MS/MS), it is possible to identify a wide range of neuropeptides in single experiments without preselecting specific peptides. Mass …

Spatial Ecology Of Mountain Lions Throughout Their Distribution In California, Kyle Duncan Dougherty

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Mountain lions (Puma concolor) have been studied extensively throughout their wide geographic distribution in the Western Hemisphere, but most research has been conducted at relatively small spatial scales. We used GPS telemetry data contributed by researchers in 16 study areas throughout California to advance understanding of mountain lion spatial ecology. First, we investigated multi-scale resource selection of mountain lions relative to spatially varying risk of intentional human-caused mortality associated with livestock depredation management. We show that individuals that proactively avoided mortality risk when selecting home ranges were able to relax their avoidance of risk when making resource selection …
