Understanding Caribou Population Cycles, 2022 University of Montana
Understanding Caribou Population Cycles, Jack R. St. John
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, harvest, climate ...

Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, 2021 A.N. Severtsov Institute of Ecology and Evolution of RAS, Russia
Molecular Genetic Analysis Of Stygobiotic Shrimps Of The Genus Xiphocaridinella (Crustacea: Decapoda: Atyidae) Reveals A Connection Between Distant Caves In Central Abkhazia, Southwestern Caucasus, Ivan Marin, Ilya Turbanov
International Journal of Speleology
Based on the morpho-genetic study of stygobiotic shrimps from the genus Xiphocaridinella Sadowsky, 1930 (Crustacea: Decapoda: Atyidae), a hydrogeological connection of a number of distant caves in Central Abkhazia of the southwestern Caucasus is satisfied, which indicates the possibility of using biospeleological studies in some cases to identify karst hydrosystems together with traditional hydrogeological methods. Moreover, a new stygobiotic atyid shrimp from the genus Xiphocaridinella, X. kelasuri sp. n., is described based on morphology and analysis of mitochondrial cytochrome oxidase I DNA sequences from three distant caves. The new species is genetically divergent from relatives and phylogenetically related to Xiphocaridinella ...

In the central nervous system of mammals, transporters localized on the presynaptic nerve terminals regulate the reuptake of neurotransmitters. These transporters are selective for a specific neurotransmitter such as dopamine (DA) and norepinephrine (NE). Specifically in the synapse, the dopamine transporter (DAT) reuptakes DA and the norepinephrine transporter (NET) reuptakes NE. However previous research has found that avian species do not have a gene for DAT, and therefore, birds may be using the NET to clear both NE and DA from the synapse. The current study aimed to extend this finding by localizing NET expression in male and female ...

Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, 2021 Kennesaw State University
Does Cortisol Respond To A Social Perturbation In Captive Bonobos?, Tiffany Ly
Symposium of Student Scholars
All animals are influenced by their environment. For social species, this means that changes in group size or composition can have long-lasting effects on survival or reproduction. When these social species are placed in captivity and new individuals are introduced suddenly by zookeepers or researchers, these events can lead to stress by changing established dominance hierarchies. For example, these interactions can cause stress hormones—like cortisol in primates and humans—to be released in response to meeting unfamiliar individuals. We took advantage of an introduction event happening at a captive research and conservation facility to better understand how introducing a ...
A Reevaluation Of The Phylogeography Of The Chattahoochee Slimy Salamander (Plethodon Chattahoochee) Using Next-Generation Genomic Data, Jadin Cross
Symposium of Student Scholars
The Plethodon glutinosus species complex is a group of large-bodied, lungless salamanders that are widespread across the eastern United States. Species in this group are morphologically cryptic and were originally delimited using allozyme data, but in most cases, the extent of contemporary gene flow between named taxa has not be rigorously evaluated. The Appalachian Mountains of northern Georgia are home to several members of this group—including P. glutinosus, P. teyahalee, P. chlorobryonis, and P. chattahoochee. P. chattahoochee has been found to be especially cryptic both morphologically and genetically as both intraspecific genetic variation and species boundaries within the P ...
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, 2021 Kennesaw State University
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Symposium of Student Scholars
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which ...

Abundance And Distribution Of The Forest Cockroaches In Different Algerian Ecosystems, Zakaria Hedjouli, Wafa Habbachi, Fatiha Masna, Saliha Benhissen, Sarra Habbachi, Abdelmadjid Yagoub Asloum, Abdelkrim Tahraoui
Journal of Bioresource Management
Forests have many insect species that are unique to biodiversity and play a crucial role in the functioning of ecosystems. Forest cockroaches are the best example of forest litter insects, which also help decompose fallen leaves. The composition of the Blattoptera fauna can vary from one region to another, depending on the habitat and numerous biotic and abiotic factors In order to study the diversity, abundance, and distribution of forest cockroaches in different Algeria ecosystems, we have selected four sites from three Wilayas: Senalba (Djelfa), Ain achir (Annaba), Seraidi (Annaba), and Lehnaya (El-taref). These sites are classified into two distinct ...
Anything For A Cheerio: Brown Capuchins (Sapajus [Cebus] Apella) Consistently Coordinate In An Assurance Game For Unequal Payoffs, 2021 University of Veterinary Medicine Vienna
Anything For A Cheerio: Brown Capuchins (Sapajus [Cebus] Apella) Consistently Coordinate In An Assurance Game For Unequal Payoffs, Lauren M. Robinson, Mayte Martínez, Kelly L. Leverett, Mattea S. Rossettie, Bart J. Wilson, Sarah F. Brosnan
Unequal outcomes disrupt cooperation in some situations, but this has not been tested in the context of coordination in economic games. To explore this, we tested brown capuchins (Sapajus [Cebus] apella) on a manual version of the Stag Hunt (or Assurance) Game, in which individuals sequentially chose between two options, Stag or Hare, and were rewarded according to their choices and that of their partner. Typically, coordination on Stag results in an equal highest payout, whereas coordinating on Hare results in a guaranteed equal but lower payoff and uncoordinated play results in the lowest payoff when playing Stag. We varied ...
Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, 2021 Research Institute for Nature and Forest
Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer
Wild boar (Sus scrofa) reappeared in Flanders, Belgium in 2006 after more than half a century of absence. Besides being a native and highly valued game species in Europe, wild boar are also known to be responsible for car collisions, crop damage, disease transmission, and ecological damage at high densities. The management of wild boar therefore seeks to balance these positive and negative impacts. Given the highly fragmented landscape in Flanders and its multifunctional use, coexistence with wild boar is only possible through integrated management involving relevant stakeholder groups. However, to be successful, this requires that the management objectives, the ...
Does Hunting Affect The Behavior Of Wild Pigs?, 2021 University of Veterinary Medicine Hannover
Does Hunting Affect The Behavior Of Wild Pigs?, Oliver Keuling, Giovanna Massei
Wild boar and feral swine (Sus scrofa) numbers are growing worldwide. In parallel, their severe ecological and economic impacts are also increasing and include vehicle collisions, damage to crops and amenities, reduction in plant and animal abundance and richness, and transmission of diseases, the latter causing billions of U.S. dollars in losses to the livestock industry each year. Recreational hunters are the main cause of mortality for this species, and hunting has traditionally been the main method to contain populations of wild pigs. Hunting might affect the behavior of the species, which potentially can lead to these animals moving ...
Environmental Impacts On The Reproduction Of Three Cold-Water Corals, With Implications For Their Vulnerability To Ocean Warming And Climate Change, Julia Johnstone
Electronic Theses and Dissertations
Cold-water corals are important habitat builders in the deep ocean worldwide. Despite being known for centuries, recent technological advances and deep-sea exploration has revealed cold-water corals thriving at depths of up to 6000m. Similar to their warm-water relatives, cold-water corals are hotspots of diversity, with their structures creating habitat for thousands of associated species. Some cold-water corals create bioherms that stretch for tens of kilometers, while others come together to form vast undersea forests. These habitats are often home to commercially important fisheries species, and conservation efforts have recently begun to regulate fishing in cold-water coral ecosystems to protect them ...

Craniometric Analysis Of European Rabbit (Oryctolagus Cuniculus) Breeds To Trace Out Intraspecific And Inter Gender Morphometric Variations, 2021 Department of Zoology, University of Okara, Okara, Pakistan
Craniometric Analysis Of European Rabbit (Oryctolagus Cuniculus) Breeds To Trace Out Intraspecific And Inter Gender Morphometric Variations, Muhammad Rizwan, Rana Manzoor Ahmad, Abdul Majid Khan, Misbah Khalid, Muhammad Wajid
Journal of Bioresource Management
The family Liproidae expresses the significant variation of morphometric features at species level. In already available literature on the European rabbit (Oryctolagus cuniculus) the idea is proposed that there can be variation in the morphometric character of different breeds of Oryctolagus cuniculus but there are negligible scientific research base evidences for it. So in this study interbreed craniometric comparison of the European rabbit is carried out to trace out their intergender and intraspecific morphometric variations. The study material consists of 32 sexually mature rabbits belong to two breeds of European rabbit that are New Zealand rabbit (eight males and eight ...

Professor Edward Drinker Cope’S Travels Through North Carolina, August–December 1869: Insights From The Transcriptions And Annotations Of Letters To His Father And His Contributions To North Carolina Ichthyology, Bryn H. Tracy, Robert E. Jenkins
Southeastern Fishes Council Proceedings
Since 1870, ichthyologists have pondered Edward Drinker Cope’s two publications: “On some Etheostomine Perch from Tennessee and North Carolina” and “A Partial Synopsis of the Fishes of the Fresh Waters of North Carolina”, along with correspondences to his father while traveling in North Carolina. We transcribed and annotated four of his letters searching for further knowledge regarding his field notebook(s) and original data (meristics, morphometrics, life coloration, etc.) from his travels across NC during Summer and Fall of 1869. However, unresolved questions remained - many related to unaccounted for periods of time. We did not achieve insights into who ...
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2019, 2021 University of Arkansas, Fayetteville
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2019, Leah English, Jennie Popp, Wayne Miller
Research Reports and Research Bulletins
Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, leading to economic activity in other parts of the economy.
This report is the fourteenth in a series that examines agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value added, employment ...
Neurotranscriptomic Changes Associated With Chick-Directed Parental Care In Adult Non-Reproductive Japanese Quail, Patricia C. Lopes, Robert De Brujin
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
For many species, parental care critically affects offspring survival. But what drives animals to display parental behaviours towards young? In mammals, pregnancy-induced physiological transformations seem key in preparing the neural circuits that lead towards attraction (and reduced-aggression) to young. Beyond mammalian maternal behaviour, knowledge of the neural mechanisms that underlie young-directed parental care is severely lacking. We took advantage of a domesticated bird species, the Japanese quail, for which parental behaviour towards chicks can be induced in virgin non-reproductive adults through a sensitization procedure, a process that is not effective in all animals. We used the variation in parental responses ...
