Self, Death, And Suicide: Does An Animal Know Of These?, Carolyn A. Ristau

Animal Sentience

Peña-Guzmán makes a strong case, using examples from the media and scientific literature, that many captive animals suffer severely. In examining the possibility of animal suicide, he dismisses the need for “reflective self-subjectivity” and “intent” in suicidal behavior. He claims that at least some animals understand “death,” citing examples of behavior he deems to be death “rituals.” But these can be more simply interpreted. The possibility of animal suicide remains more dubious than Peña-Guzmán suggests.

Changes In Behavior And Emotion Under Chicken Domestication, Martin Johnsson

Animal Sentience

Marino’s target article provides an overview of chickens’ cognition, emotion, and personality, with the aim of changing how people view chickens. In this commentary, I will agree that chickens deserve better than their reputation, but contend with a statement about the lack of behavioral change under chicken domestication.

Research On Alleculinae (Coleoptera: Tenebrionidae: Alleculinae) Intugai Forests Of The Almaty Region In Kazakhstan Using Window Traps, Oto Nakladal, Vladimir Novak, Yuliya Kolesnichenko

Turkish Journal of Zoology

We used 140 passive flight interception window traps for survey of alleculines in tugai forests of the Almaty region in Kazakhstan. Traps were set on Fraxinus sogdiana (Bunge, 1854), Populus diversifolia (Schrenk, 1842), P. pruinosa (Schrenk, 1845), and Elaeagnus angustifolia (Linnaeus, 1753), which are the main tree species of tugai forests. Two species of alleculines were captured: Mycetochara flavipes (Fabricius, 1792) and Steneryx dejeani (Faldermann, 1836). Mycetochara flavipes significantly prefers areas of the tugai forests with dominancy of Elaeagnus angustifolia. Faunistic data for both species are given. Mycetochara flavipes was recorded as a new species and genus for the territory …

Experiment Versus Analogy In The Search For Animal Sentience, Geoffrey Hall

Animal Sentience

Deciding between rival accounts of an instance of an animal’s behavior can frequently be achieved by experimental tests of different predictions made by the alternatives. When, however, one (or both) of the alternatives is expressed in terms of the mental state of the animal, an experimental test to distinguish them can be hard to find. Although it is unsatisfactory in many ways, it may be necessary to fall back on argument from analogy with human behavior and experience.

Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck

Animal Sentience

Zentall’s (2016) model of cognitive dissonance is compatible with cognitive continuity between humans and nonhumans. It may help explain cognitive dissonance-like behavior in many species, including humans. It is also consistent with Tinbergen’s (1963) ‘four whys’ in ethological explanation.

Marketing Tips For Small-Scale, Local Honey Bee Keepers In Northwest Arkansas, Samuel L. Goll, Michael P. Popp, Jennie S. Popp, Donald C. Steinkraus

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The objective of this thesis was to gain market information for beekeepers regarding different honey bee products and to provide information about economic feasibility when produced on a small, local scale. Since cost-of-production information about operating an apiary is widely available, the focus of this work was on gaining marketing knowledge. One of the objectives of the surveys was to develop a better sense of what potential resellers of honey bee products considered locally produced. Another objective was to determine preferences for honey bee product packaging as well as bee pollination services. Using that feedback, a marketing plan for different …

A Description Of Variation In Fecundity Between Two Populations Of Wolf Spider Rabidosa Rabida In Searcy Arkansas Using Brood Size Measurements, Brandon Hogland, Ryan Stork, Amber Hug

Journal of the Arkansas Academy of Science

Fecundity, a very important population variable, can be estimated by measuring the number of juveniles hatching out of individual egg sacs. Rabidosa rabida is a large wolf spider that is common in Arkansas and much of the eastern portion of North America. This study attempts to expand previous estimates of variation in fecundity made for this species by Reed and Nicholas in Mississippi. We hypothesized that a significant variation would be found in fecundity estimates between two populations in Arkansas. We also hypothesized that this variation would be similar to the variation reported in Mississippi. Two populations of R. rabida …

Lemurfaceid: A Face Recognition System To Facilitate Individual Identification Of Lemurs, David Crouse, Rachel L. Jacobs, Zach Richardson, Scott Klum, Anil Jain, Andrea L. Baden, Stacey R. Tecot

Publications and Research

Background: Long-term research of known individuals is critical for understanding the demographic and evolutionary processes that influence natural populations. Current methods for individual identification of many animals include capture and tagging techniques and/or researcher knowledge of natural variation in individual phenotypes. These methods can be costly, time-consuming, and may be impractical for larger-scale, populationlevel studies. Accordingly, for many animal lineages, long-term research projects are often limited to only a few taxa. Lemurs, a mammalian lineage endemic to Madagascar, are no exception. Long-term data needed to address evolutionary questions are lacking for many species. This is, at least in part, due …

Factors Influencing Mountain Lion Kill Rates Across Three Ecosystems In The Americas, Steven Cross

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Kill rate, defined as the number of prey killed per predator per unit time, is a key component to understanding predator-prey dynamics. A multitude of factors may affect kill rates, including, variation in age, sex, weight, or presence of offspring of either predator or prey species (intraspecific variation) and events such as the theft of a kill made by another animal (kleptoparasitism). These factors may influence the time a predator spends locating prey (search time) and the pursuing, killing, and consumption of prey (handling time). The sum of search time and handling time may be measured as the time between …

Description Of Immature Stages Of Culicoides Peregrinus (Diptera: Ceratopogonidae),A Potent Vector Of Bluetongue Virus, Rupa Harsha, Nilotpol Paul, Abhijit Mazumdar

Turkish Journal of Zoology

Detailed descriptions of the immature stages, i.e. eggs, larvae, and pupae, of Culicoides peregrinus Kieffer were made based on scanning electron microscopy and bright field microscopy. Measurements of different larval instars were also studied. Wild engorged females were collected by UV light trap and made to oviposit under laboratory conditions onto wet filter paper within glass vials. Among the laid eggs, embryonated eggs were reared in artificial rearing medium in the laboratory for obtaining life stages. The immature stages were also collected from their natural habitat (cattle manure) and subsequently processed and described.

Efect Of Dual Growth Factor Administration On Oxidative Markers During Acute Stage Wound Healing In Rats, Bahar Di̇ndar, Kaan Kaltalioğlu, Şule Coşkun Cevher

Turkish Journal of Zoology

Wound healing is a complex process affected by various conditions, including oxidative stress. The present study explored the time-dependent effects of platelet-derived growth factor (PGDF) and vascular endothelial growth factor (VEGF) administration on oxidative markers during acute stage wound healing. Thirty-six Wistar rats were distributed into three major groups; skin wounds were inflicted in all groups. The wounds were either left untreated (control group), treated topically with blank chitosan gel (blank chitosan gel group), or treated topically with a combination of PDGF and VEGF in chitosan gel (PDGF + VEGF chitosan gel group). Wounds were sampled on postsurgery days 3 …

Seasonal Pattern Of Population Dynamics, Spawning Activities, And Diet Composition Of Sardine (Sardina Pilchardus Walbaum) In The Eastern Adriatic Sea, Barbara Zorica, Vanja Cikes Kec, Olja Vi̇djak, Viktor Kraljevic, Goran Brzulja

Turkish Journal of Zoology

Monthly samples from commercial catches obtained with purse seiners operating in the Croatian fishing grounds (eastern Adriatic Sea) were collected throughout 2013, excluding January and December due to a fishing ban. Overall, 1010 sardine individuals were analyzed. Total body length ranged from 10.4 to 17.6 cm (mean ± SD: 13.9 ± 1.28 cm). Slightly larger individuals were caught during autumn at the beginning of the spawning season. Analysis of length-mass relationship showed that sardine specimens grow isometrically (b = 3.063). Seasonal oscillations of condition factor indicated that the examined specimens were in the best condition at the beginning of the …

Species Diversity And Community Structure Of Zooplankton In Threedifferent Types Of Water Body Within The Sakarya River Basin, Turkey, Pinar Gürbüzer, Özge Buyurgan, Çağri Tekatli, Ahmet Altindağ

Turkish Journal of Zoology

The aim of this study was to identify differences between different types of water body within the same river basin by comparing the composition of the zooplankton community. The study was conducted in three types of water body in the Sakarya Basin in northwestern Turkey: an alluvial barrier lake (Lake Poyrazlar), a pond (Sorgun Pond), and a reservoir (Çubuk II Reservoir). The spatiotemporal changes of these three types of aquatic habitats were investigated in terms of the zooplankton organisms by examining their diversity, evenness, and differences in the abundance of species. A total of 81 species were identified. Thirty-eight species …

Diet Selection Of Snow Leopard (Panthera Uncia) In Chitral, Pakistan, Rukhsana Khatoon, Iftikhar Hussain, Maqsood Anwar, Muhammad Ali Nawaz

Turkish Journal of Zoology

Snow leopard (Panthera uncia) is an elusive endangered carnivore found in remote mountain regions of Central Asia, with sparse distribution in northern Pakistan, including Chitral and Baltistan. The present study determined the food habits of snow leopard, including preferred prey species and seasonal variation in diet. Fifty-six scat samples were collected and analyzed to determine the diet composition in two different seasons, i.e. summer and winter. Hair characteristics such as cuticular scale patterns and medullary structure were used to identify the prey. This evidence was further substantiated from the remains of bones, claws, feathers, and other undigested remains found in …
