Effects Of Timing Of Local Anesthesia On Physiological Responses In Calves After Dehorning, Amanda Jane Mathias
Effects Of Timing Of Local Anesthesia On Physiological Responses In Calves After Dehorning, Amanda Jane Mathias
LSU Master's Theses
The American Veterinary Medical Association has stated the importance of minimizing pain associated with dehorning to limit the amount of distress and changes in the animal’s behavior and physiological states (AVMA, 2014b). The following studies aim to determine the effect of timing of lidocaine administration on physiological responses in calves after dehorning. The first study compared cortisol and substance P levels in calves dehorned immediately after administration of lidocaine and meloxicam, calves dehorned 10 minutes after the administration of lidocaine and meloxicam, and calves that were administered lidocaine and meloxicam and not dehorned. It was concluded waiting 10 minutes after …
Chicken Of The Sea, Jonathan Balcombe
Chicken Of The Sea, Jonathan Balcombe
Animal Sentience
Marino summarizes research showing that chickens perform cognitively and emotionally at a higher level than previously assumed. Here, I describe capacities of teleost fishes that parallel those of chickens, including the ability to recognize human faces, perspective-taking, and referential communication. Research on chickens and on fishes reveals an emerging trend in cognitive ethology: abilities once thought limited to a scant few highly intelligent non-humans may actually occur broadly across taxa.
Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala
Canine Emotions As Seen Through Human Social Cognition, Miiamaaria V. Kujala
Animal Sentience
It is not possible to demonstrate that dogs (Canis familiaris) feel emotions, but the same is true for all other species, including our own. The issue must therefore be approached indirectly, using premises similar to those used with humans. Recent methodological advances in canine research reveal what dogs experience and what they derive from the emotions perceptible in others. Dogs attend to social cues, they respond appropriately to the valence of human and dog facial expressions and vocalizations of emotion, and their limbic reward regions respond to the odor of their caretakers. They behave differently according to the …
Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs
Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs
Animal Sentience
I discuss three themes related to Kujala’s target article. First, the wealth of emerging data on cognitive studies in dogs will surely show that dogs have a very rich repertoire of cognitive processes, for most of which we find homologues in humans. Second, understanding the internal states that mediate social behaviors, such as emotions, requires us to consider both a dog’s behaviors with other dogs, and the emergence of new behavioral patterns in interaction with humans. Third, all of this will certainly narrow the range of justifications for denying that dogs have subjective experiences of emotions.
Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr.
Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr.
Animal Sentience
I explore how the findings reviewed by Kujala (2017) influence our understanding of the human-dog bond. The special social cognitive abilities of dogs may be unique among animal species, probably influenced by the circumstances surrounding canine domestication. The bond has influenced animal welfare policies, giving dogs a privileged place among animals. To determine what protections other species should have in a rational animal welfare policy, more research is needed on whether other species have similar social cognitive abilities.
Empathy In Dogs: With A Little Help From A Friend – A Mixed Blessing, Sabrina Karl, Ludwig Huber
Empathy In Dogs: With A Little Help From A Friend – A Mixed Blessing, Sabrina Karl, Ludwig Huber
Animal Sentience
Kujala (2017) presents an extensive overview of existing research on canine emotions in comparison to those of other non-human animals and humans. This commentary provides some additional research results on the intensively debated field of empathy in dogs. We focus on recent advances in the understanding of a fundamental building block of empathy — emotional contagion — and on dogs’ remarkable sensitivity for human emotions, including the skills of assistance dogs.
Positive Emotions And Quality Of Life In Dogs, Patrizia Piotti
Positive Emotions And Quality Of Life In Dogs, Patrizia Piotti
Animal Sentience
Positive affect is fundamental to ensuring good animal welfare. Discrete and dimensional theories of emotion have recently been used to explore the relation between cognition and affect and to develop cognitive measures of positive affect. Human quality-of-life assessment focuses on positive affect, which is difficult to measure objectively in dogs. Expanding on Kujala’s (2017) discussion of positive emotions and cognitive measures of affect, I suggest how these are relevant to assessing canine quality of life.
Inferring Emotion Without Language: Comparing Canines And Prelinguistic Infants, Stefanie Hoehl
Inferring Emotion Without Language: Comparing Canines And Prelinguistic Infants, Stefanie Hoehl
Animal Sentience
Research on canine emotions has to deal with challenges quite similar to psychological research on social and emotional development in human infants. In both cases, verbal reports are unattainable, and behavioral and physiological methods have to be adjusted to the specific population. I will argue that both regarding empirical approaches and conceptual work, advances in research on social-cognitive development in human infants can inform the study of canine emotions.
Taxonomic Status Of A Newly Described Island Population Of The Smooth Newtlissotriton Vulgaris (Linnaeus, 1758) From Bozcaada (Çanakkale, Turkey), Nurşen Çördük, Çi̇ğdem Gül, Murat Tosunoğlu, Konstantinos Sotiropoulos
Taxonomic Status Of A Newly Described Island Population Of The Smooth Newtlissotriton Vulgaris (Linnaeus, 1758) From Bozcaada (Çanakkale, Turkey), Nurşen Çördük, Çi̇ğdem Gül, Murat Tosunoğlu, Konstantinos Sotiropoulos
Turkish Journal of Zoology
The taxonomic status and phylogenetic position of the recently recorded smooth newt (Lissotriton vulgaris) population from the island of Bozcaada (Çanakkale, Turkey) is clarified on the basis of morphological and molecular phylogenetic analyses. The L. vulgaris population from Bozcaada presents body proportions and morphological features of subsp. schmidtlerorum, such as small body length, absence of the tail filament, and dorsal crest with pointed free margin. Similarly, phylogenetic analyses of mitochondrial DNA sequences (ND4, 16S rRNA) place the Bozcaada population within Clade E of the recent L. vulgaris phylogeny, which consists of L. v. schmidtlerorum populations.

First Record Of Water Bears (Tardigrada) From Sponges (Porifera), Joanna Talanda, Krzysztof Zawierucha
First Record Of Water Bears (Tardigrada) From Sponges (Porifera), Joanna Talanda, Krzysztof Zawierucha
Turkish Journal of Zoology
Aquatic species of Tardigrada usually inhabit submerged plants or sediment but they are also known as associated with other animals, like barnacles (Crustacea: Cirripedia) or sea cucumbers (Echinodermata: Holothuroidea). In sponges collected from Lake Ohrid (Macedonia) we found individuals of two tardigrade taxa: Isohypsibius sp. and Dactylobiotus sp. This paper provides the first record of Tardigrada from Macedonia (Lake Ohrid) and is the first report of these animals on sponges.

Oocyte Development In Melanogryllus Desertus (Pallas, 1771) (Orthoptera: Gryllidae):Presence Of Balbiani Body, Özlem Çakici
Oocyte Development In Melanogryllus Desertus (Pallas, 1771) (Orthoptera: Gryllidae):Presence Of Balbiani Body, Özlem Çakici
Turkish Journal of Zoology
Oocyte development in the ovary of the black cricket, Melanogryllus desertus, was investigated. In the panoistic ovary of M. desertus, oocyte developmental stages based on their histological properties were classified as previtellogenic, vitellogenic, and maturation. Oocytes were encircled by follicle cells through the developmental stages. In the previtellogenic stage, a few vacuoles were observed just beneath the oolemma. At the beginning of the vitellogenic stage, subdivided into early-, middle-, and late-vitellogenic stages, yolk granules within the oocyte were initially observed just beneath the oolemma. In addition, small lipid droplets were initially present under the yolk granules. As vitellogenesis proceeded, both …

Chondrocranial Differences In Bufotes Variabilis (Anura: Bufonidae):Geometric Morphometric Comparison With Two Anuran Species, Eli̇f Yildirim, Uğur Kaya
Chondrocranial Differences In Bufotes Variabilis (Anura: Bufonidae):Geometric Morphometric Comparison With Two Anuran Species, Eli̇f Yildirim, Uğur Kaya
Turkish Journal of Zoology
Few studies have focused on a detailed morphological description of the chondrocranium of bufonids. This study examines Bufotes variabilis, which is one of the widespread clades of neobatrachian anurans. We used geometric morphometrics to analyze variations of the chondrocranial shape in B. variabilis and a comparison was made with Rana macrocnemis and Hyla orientalis. Results indicated that B. variabilis is clearly different from the other species based on the presence of a bigger otic process, a more anterior position of the muscular process of the palatoquadrate, and a narrower articular process of the palatoquadrate. H. orientalis and R. macrocnemis are …

Effects Of Aluminum, Copper, And Titanium Nanoparticles Onsome Blood Parameters In Wistar Rats, Esi̇n Gülnaz Canli, Mustafa Canli
Effects Of Aluminum, Copper, And Titanium Nanoparticles Onsome Blood Parameters In Wistar Rats, Esi̇n Gülnaz Canli, Mustafa Canli
Turkish Journal of Zoology
In this study, Al2O3, CuO, and TiO2 nanoparticles (NPs) were individually administered to 60 mature female rats via oral gavage (0, 0.5, 5, and 50 mg/kg b.w. per day) for 14 days and then responses of ATPases in the erythrocytes, total oxidant status (TOS), total antioxidant status (TAS), and liver enzyme (alkaline phosphatase, ALP; alanine transaminase, ALT; aspartate transaminase, AST) levels in the serum were determined. There were sharp decreases in Na,K-ATPase activity in the erythrocytes following NP exposures. All doses of CuO caused significant (P < 0.05) inhibitions in Na,K-ATPase activity (up to 94%), while only higher doses of Al2O3 and TiO2 inhibited (76%-80%) the activity of Na,K-ATPase. Oppositely, the activities of Ca-ATPase (up to 274%) and Mg-ATPase (up to 290%) increased significantly following TiO2 exposures. TOS levels significantly increased following Al2O3 (167%) and CuO (240%) exposures, though TAS levels did not change significantly in any of the exposure groups. The levels of ALP, AST, and ALT increased following NP administrations. Ti-NP increased the levels of all liver enzymes in the serum (up to 84%), while Al-NP (58%) and Cu- NP (43%) increased only ALP levels. The present study demonstrated evidence of the toxic effects of NPs, as they altered the measured parameters in the blood, and suggests further research to better understand the environmental fate of NPs.

Can Montane And Cave Centipedes Inhabit Soil?, Ivan Hadrian Tuf, Oldrich Kopecky, Jan Mikula
Can Montane And Cave Centipedes Inhabit Soil?, Ivan Hadrian Tuf, Oldrich Kopecky, Jan Mikula
Turkish Journal of Zoology
Communities of centipedes (Chilopoda) were studied at three localities in eastern Bohemia (Czech Republic) near the town of Skutec using modified subterranean traps. Centipedes were trapped separately from depths of 5, 15, 25, 35, 45, 55, 65, 75, 85, and 95 cm to allow evaluation of the vertical distribution in the soil. Presence of centipedes in deeper soil profiles is related to their ability to colonize the subterranean environment. Lithobius tenebrosus fennoscandius, L. lucifugus, L. macilentus, Cryptops parisi, Strigamia acuminata, and S. transsilvanica inhabited deeper soil layers preferentially. This study shows that soil can be inhabited by cave centipedes or …
Hedychridium Monochroum And Chrysis Lanceolata (Hymenoptera: Chrysididae)- Two Species Of Cuckoo Wasps Reared From Nests Of Solierella Compedita (Hymenoptera: Crabronidae) In Southeastern Ukraine, Kateryna Martynova
Turkish Journal of Zoology
The crabronid wasp Solierella compedita (Piccioli, 1969) occupied artificial trap-nests in southeastern Ukraine. Cuckoo wasps Hedychridium monochroum du Buysson, 1888 and Chrysis lanceolata Linsenmaier, 1959 were reared from its nests. Thus, the host-parasitoid association between S. compedita and Ch. lanceolata is recorded for the first time and the association between S. compedita and H. monochroum is confirmed. The larva of H. monochroum and the minute cocoon structure of both reared chrysidids are described. Wide color variability is shown for H. monochroum. The feeding habits of larvae for both chrysidids are discussed.

Diversity Of Zooplankton In Municipal Wastewater-Contaminatedurban Pond Ecosystems Of The Lower Gangetic Plains, Shuvadip Adhikari, Abhishek Roy Goswami, Subhra Kumar Mukhopadhyay
Turkish Journal of Zoology
The present limnological investigation was conducted to study zooplankton diversity in municipal wastewater-contaminated ponds in light of their contributions to the ecosystem. It is revealed by the present study that the physicochemical factors of the study sites are regulated by wastewater input and anthropogenic activities. A good number of zooplankton species thrived in these ponds (22 species of zooplankton, including 14 species of Rotifera, 3 species of Copepoda, 4 species of Cladocera, and a single species of Ostracoda), which suggests that the municipal wastewater, loaded with various nutrients, has influenced the zooplankton diversity and abundance. Site 3, a well-managed fishpond, …
