Insect-Specific Peptides In The Venom Of Wolf Spiders (Araneae: Lycosidae), Hafiz Muhammad Tahir, Khanum Zahra, Azhar Abbas Khan Jan 2018

Insect-Specific Peptides In The Venom Of Wolf Spiders (Araneae: Lycosidae), Hafiz Muhammad Tahir, Khanum Zahra, Azhar Abbas Khan

Turkish Journal of Zoology

The venom of two dominant species of wolf spiders, Pardosa sumatrana Thorell and Pardosa birmanica Simon, was extracted and characterized. Insecticidal potential of crude venom and selected peptide fractions (i.e. 35-kDa fraction of both spiders) was evaluated in the laboratory using Rhopalosiphum padi (Linnaeus) (Homoptera: Aphididae) as a model pest. Results of the study showed that both the crude venom and the protein fractions caused significantly higher mortality in treated aphids compared to the control. It is concluded that both the crude venom and the protein fractions possess insecticidal potential.

Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve Jan 2018

Do Avian Blood Parasites Influence Hypoxia Physiology In A High Elevation Environment?, Farah Ishtiaq, Sahas Barve

Biological Sciences Faculty Publications

BACKGROUND: Montane birds which engage in elevational movements have evolved to cope with fluctuations in environmental hypoxia, through changes in physiological parameters associated with blood oxygen-carrying capacity such as haemoglobin concentration (Hb) and haematocrit (Hct). In particular, elevational migrants which winter at low elevations, encounter varying intensities of avian haemosporidian parasites as they traverse heterogeneous environments. Whilst high intensity parasite infections lead to anaemia, one can expect that the ability to cope with haemosporidian infections should be a key trait for elevational migrants that must be balanced against reducing the oxygen-carrying capacity of blood in response to high elevation. In …

Changes Of Hypothalamic-Pituitary-Testicular Axis In Male Rats During Cognitive Impairment, Patteera Wititsuwankul Jan 2018

Changes Of Hypothalamic-Pituitary-Testicular Axis In Male Rats During Cognitive Impairment, Patteera Wititsuwankul

Chulalongkorn University Theses and Dissertations (Chula ETD)

From the previous reports denoting that hypothalamus regulating reproductive function via hypothalamic-pituitary-testicular (HPT) axis, and hippocampus controlling learning and memory capacity can synthesize reproductive hormones, and that cognitive impairment particularly occurs during reproductive senescence, it leads to the following research questions; i) which system first enters the aging stage and ii) how the changes are related. Male rats at the ages of 4, 6, 8, 10 and 12 months old were subjected for this study. Blood samples were collected for serum testosterone (T) and luteinizing hormone (LH) assays by enzyme-linked immunosorbent assay (ELISA) techniques. Testes, seminal vesicle, prostate gland and …

Effects Of Alpha-Mangostin On Hematopoiesis In Zebrafish Danio Rerio (Hamilton, 1822) Embryos, Wannakarn Kitipaspallop

Chulalongkorn University Theses and Dissertations (Chula ETD)

Alpha-mangostin (AM) is in the xanthone group and a main compound extracted from mangosteen (Garcinia mangostana Linn.). It is effective in antioxidant, antimicrobe and anticancer activities. However, the underlying side effects on normal cells, especially in hematopoiesis have not been investigated completely. In this research, it was aimed to elucidate the possible effects of AM on hematopoiesis using zebrafish (Danio rerio) embryos as a representative model. The results showed that AM could cause the zebrafish embryonic mortality with the concentration dependent manner. The median lethal concentration (LC50) of AM at 72 h was 5.75 ± 0.26 µM. In addition, AM …

Sibling Rivalry: A Comparison Of Giant Panda (Ailuropoda Melanoleuca) Twin Behavior, Taryn Chudo

Undergraduate Honors Thesis Projects

Expanded knowledge on an animal’s individual behavior would be useful in reintroduction programs for endangered species around the globe. Currently, reintroduction program criteria focus primarily on physical characteristics such as age, sex, and overall health for the selection of candidates. However, behavioral deficiencies have been found in captive populations, producing adverse effects on reintroduction program success. The giant panda (Ailuropoda melanoleuca) is a species that would benefit from understanding the impact of behavior on reintroduction success. This study focused on the relationship of behavior with kinship, birth weight and age. No significant correlation was found between birth weight …

Characterizing Curiosity-Related Behavior In Bottlenose (Tursiops Truncatus) And Roughtoothed (Steno Bredanensis) Dolphins, Malin Lilley, Amber J. De Vere, Deirdre Yeater, Stan A. Kuczaj Ii

Psychology Faculty Publications

Dolphins are frequently described as curious animals; however, there have been few systematic investigations of how dolphins behave when they are curious and the extent to which individual differences in curiosity exist in dolphins. Previous research has described individual differences in dolphins’ frequency of interactions with environmental enrichment as well as quantifying curiosity-related traits of dolphins via personality assessments, though behavioral observation and trait rating components have not been part of the same study. The present study describes two different experiments designed to elicit curiosity in 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis) dolphins. …

Canid Vs. Canid: Insights Into Coyote-Dog Encounters From Social Media, Erin E. Boydston, Eric S. Abelson, Ari Kazanjian, Daniel T. Blumstein

Human–Wildlife Interactions

While the relationship between coyotes (Canis latrans) and house cats (Felis catus) may be characterized as one between predators and their prey, coyote interactions with domestic dogs (C. lupus familiaris) appear to be more varied and may include behaviors associated with canid sociality. While encounters between coyotes and dogs are difficult to observe, we capitalized on publically available video recordings of coyote-dog encounters to observe canid behaviors and examined 35 video clips downloaded from YouTube during fall 2014. We identified coyote-dog interactions that were playful, agonistic, or predatory; those that we could not clearly …

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long Jan 2018

Strike Hazard Posed By Columbids To Military Aircraft, Melanie R. Colón, Ashley M. Long

Human–Wildlife Interactions

Wildlife-aircraft strikes threaten both human and animal safety and result in hundreds of millions of dollars per year in aircraft damage and lost flight hours. Large-bodied birds are especially hazardous to aircraft. However, given high-speed flight at low altitudes, military aircraft may be especially vulnerable to strikes and more susceptible to damage even when encountering small birds. We summarized all wildlife-aircraft strike records from Randolph Air Force Base (San Antonio, Texas) over a 25-year period and compared the number and cost of strikes across avian species and species groups. Because columbids (i.e., pigeons and doves) are among the most frequently …

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young Jan 2018

Post-Release Activity And Habitat Selection Of Rehabilitated Black Bears, Patrick J. Myers, Julie K. Young

Human–Wildlife Interactions

Despite the long history of wildlife rehabilitation and the abundance of empirical knowledge of the behavior and resource selection of wildlife species, rarely does research bridge these disciplines. Such investigations could be of value to wildlife managers and rehabilitators by revealing the suitability of the habitat at selected release sites, the wild activities, behavior, and fitness of the captive-reared individuals, and ultimately the efficacy of the rehabilitation process. Rehabilitated carnivores warrant specific attention, given that they are wide-ranging and may behave in ways that threaten human safety or interests. We investigated the behavior of orphan, rehabilitated black bear cubs ( …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger Jan 2018

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger

Human–Wildlife Interactions

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

Fish Consciousness, David Gamez Jan 2018

Fish Consciousness, David Gamez

Animal Sentience

Woodruff makes two arguments to support his claim that ray-finned fish are conscious: (1) Fish neuroanatomy has similarities with the structures in the human brain that support consciousness. (2) The complexity and flexibility of fish behaviour suggest that they are conscious. This commentary will argue that neither the neuroanatomical nor the behavioural argument can provide conclusive evidence for consciousness in fish. We should suspend judgement until we have discovered mathematical theories of consciousness that can reliably map between states of consciousness and states of the physical world.

Canine Emotions: Guidelines For Research, Miiamaaria V. Kujala Jan 2018

Canine Emotions: Guidelines For Research, Miiamaaria V. Kujala

Animal Sentience

In the target article, I called for a discussion on the nature and extent of dogs’ emotions. The commentators generally agreed on the existence of dog emotions, but the diversity and quality of dog emotions, as well as the influence of human social cognition on perceiving dog emotions, raised more debate. To respond to the stimulating commentaries, I touch briefly on the philosophy of (canine) mind and discuss further the benefits of comparing cognition across species, secondary emotions, and the shaping of canine emotions by evolution, breeding and experience. I conclude with suggestions for future research guidelines on studies of …

Evidence For Extra-Gastric Expression Of The Proton Pump H+/K+ -Atpase In The Gills And Kidney Of The Teleost Oreochromis Niloticus, Ebtesam Barnawi Jan 2018

Evidence For Extra-Gastric Expression Of The Proton Pump H+/K+ -Atpase In The Gills And Kidney Of The Teleost Oreochromis Niloticus, Ebtesam Barnawi

Theses and Dissertations (Comprehensive)

It is well known that stomach acid secretion by oxynticopeptic cells of the gastric mucosa is accomplished by the H+/ K+-ATPase (HKA), which is comprised of the HKα1 (gene: atp4a) and HKβ (gene: atp4b) subunits. However, the role of the HKA in extra-gastric organs such as the gill and kidney is less clear especially in fishes. This pump may contribute to active ion and/or acid-base regulation either through direct ion transport or through secondary transport proteins against unfavorable concentration gradients via the energy derived from ATP hydrolysis.
