Current Invasions Of East Asian Cyclopoids (Copepoda, Cyclopoida)In Europe: New Records From Eastern Ukraine, Elena Anufriieva, Nickolai Shadrin
Turkish Journal of Zoology
The East Asian freshwater cyclopoid copepods Mesocyclops pehpeiensis (Hu, 1943) and Eucyclops roseus Ishida, 1997, which are new for Europe, were recorded from samples collected in the water bodies of the city of Lugansk, eastern Ukraine. In 2012 the same species of cyclopoids, new or rare for Europe, were found in Crimean ponds where there is no human agency that could lead to introductions of alien species. Long-distance transportation by birds, probably, is the more plausible explanation for their appearance in Lugansk. These alien species were found in newly formed water bodies without stable communities, which may serve as a …
A New Species Of Athripsodes From The Southwest Of The Iberian Peninsula (Trichoptera, Leptoceridae), Luis Martín González, Marcos Gonzalez, Jesus Martínez
A New Species Of Athripsodes From The Southwest Of The Iberian Peninsula (Trichoptera, Leptoceridae), Luis Martín González, Marcos Gonzalez, Jesus Martínez
Turkish Journal of Zoology
A new species of the genus Athripsodes from the Iberian Peninsula is described and illustrated: Athripsodes alentexanus sp. Nov. Adults of the new species are close to those of A. Taounate Dakki and Malicky, 1980 and A. Ygramul Malicky and Lounaci, 1987, but the shape of their inferior appendages provides the most striking distinction between males of these three species.

Turkish Journal of Zoology
Four patches of poplar forest with different dike histories (about 30 to 200 years) were selected from the coastal area of Yancheng, China, for detecting the effect of dike age on soil macrofauna. A total of 825 individuals belonging to 21 taxonomic groups were collected. Omnivorous, phytophagous, predaceous, and saprophagous groups were classified on the basis of diet. Higher biodiversity values were observed in the forests with longer dike histories (100 and 200 years) than in those with shorter dike histories (30 and 50 years). By principal coordinate analysis, the soil macrofaunal communities from the forests were distinguished as three …

Turkish Journal of Zoology
Hyla is one of the genera in the family Hylidae that is distributed in the Old World. Three tree frog species of this genus are distributed in Eurasia and especially inhabit semiaquatic regions. Several studies were conducted on the genus with different methodologies to delimit the species level. In the present study, we modeled the potential distribution areas for three frogs (Hyla orientalis, Hyla savignyi, and Hyla felixarabica) to determine the suitable habitat of each species separately. Models of all three species had a good fit as indicated by the high area under the curve (AUC) values (H. Orientalis = …

Turkish Journal of Zoology
In this study, 50 female and 50 male 5-month-old captive-bred chukar partridges (Alectoris chukar) were released in 2012 into nature and monitored in the Çamkuyular Cedar Research Forest, Elmalı, Antalya. All individuals were tagged with colored leg tags and 15 also had radio transmitters attached. Over 4 months, the chukars were hunted by their natural predators, with the last dead bird found in January 2013. Of the 33 dead birds, 60.6% (n: 20) had been killed by large mammals and 39.4% (n: 13) by predatory birds. This study indicates that chukars produced in captivity are unable to successfully adapt to …

The Effect Of Dgat1 Polymorphism On Milk Production Traits In Dairycows Depending On Environmental Temperature, Jolanta Komisarek, Mateusz Kolenda
The Effect Of Dgat1 Polymorphism On Milk Production Traits In Dairycows Depending On Environmental Temperature, Jolanta Komisarek, Mateusz Kolenda
Turkish Journal of Veterinary & Animal Sciences
It has long been known that a hot environment negatively influences milk production in cattle. Although molecular mechanisms underlying this phenomenon to a great extent remain to be recognized, they include alterations in lipid metabolism. DGAT1 plays a key role in the synthesis of triacylglycerols and polymorphism of this gene has been proven to have a pronounced influence on milk production. The aim of this study was to establish if the effect of DGAT1:p.K232A on milk-related traits is dependent on environmental thermal conditions. The analysis, performed on 468 cows of the Polish Holstein-Friesian breed, showed that allele DGAT1:K232 significantly increased …

Pain In Parallel, Peter Godfrey-Smith
Pain In Parallel, Peter Godfrey-Smith
Animal Sentience
Key's (2016) arguments against the view that fish feel pain can be shown to be fallacious by considering some damage-related behaviors in invertebrates. Pain may have different neural bases in different organisms, so the absence in fish of the cortical structures that might underlie pain in mammals does not settle the question of fish pain.
Nonverbal Indicators Of Pain, Simon Van Rysewyk
Nonverbal Indicators Of Pain, Simon Van Rysewyk
Animal Sentience
In discussing fish pain, Key (2016) privileges pain in humans — “the only species able to directly report on its feelings.” Human experience of pain is not necessarily best reflected by verbal self-report, however. Neural responses to noxious stimuli are influenced by individual differences and by context. Nonverbal pain displays such as facial expressions reflect part of the neural response to noxious stimuli. Most mammals have a specific facial grimace reflecting pain. If fish have a somatic expression of pain, the development of a reliable and accurate somatic pain scale specific to fish could make a contribution to the debate …

More nonindigenous species occur in Florida, USA, than any other region worldwide and may threaten many of Florida’s natural resources. The frequency of new reports mandates the need for regular updates. Herein, we use photographic and specimen vouchers in addition to literature records to provide updated information on verified nonindigenous amphibians and reptiles in Florida. Between our most recent summary in 2012 and the end of 2015, 38 additional species are known to have been intercepted (n = 2) or introduced (n = 36). We also update the invasion stage of seven species previously reported from Florida and …
The Contribution Of Marine Aggregate-Associated Bacteria To The Accumulation Of Pathogenic Bacteria In Oysters: An Agent-Based Model, Andrew M. Kramer, J. Evan Ward, Fred C. Dobbs, Melissa L. Pierce
The Contribution Of Marine Aggregate-Associated Bacteria To The Accumulation Of Pathogenic Bacteria In Oysters: An Agent-Based Model, Andrew M. Kramer, J. Evan Ward, Fred C. Dobbs, Melissa L. Pierce
OES Faculty Publications
Bivalves process large volumes of water, leading to their accumulation of bacteria, including potential human pathogens (e.g., vibrios). These bacteria are captured at low efficiencies when freely suspended in the water column, but they also attach to marine aggregates, which are captured with near 100% efficiency. For this reason, and because they are often enriched with heterotrophic bacteria, marine aggregates have been hypothesized to function as important transporters of bacteria into bivalves. The relative contribution of aggregates and unattached bacteria to the accumulation of these cells, however, is unknown. We developed an agent-based model to simulate accumulation of vibrio-type bacteria …
The Nutritional Value Of Fecal Sacs: Testing The Parental Nutrition Hypothesis, Amanda W. Burns
The Nutritional Value Of Fecal Sacs: Testing The Parental Nutrition Hypothesis, Amanda W. Burns
College of Graduate Studies: Theses & Dissertations
Nest sanitation is an important aspect of parental investment in birds with altricial nestlings. Passerine nestlings produce fecal matter that is encased in a mucous membrane for easy disposal. These fecal sacs are either removed from the nest and transported a distance away or they are ingested by the adult. A decline in fecal sac ingestion rates as nestlings age has been observed in several species. The parental nutrition hypothesis posits that this pattern can be attributed to increasing digestive efficiency as nestlings age. The parental nutrition hypothesis makes three predictions: fecal sac consumption rates should decrease as nestlings age, …
Detection Of Yersinia Enterocolitica Serotype O:9 In The Faeces Of Cattle With False Positive Reactions In Serological Tests For Brucellosis In Ireland, Don O'Grady, Kevin Kenny, Seamus Power, John Egan, Fergus Ryan
Detection Of Yersinia Enterocolitica Serotype O:9 In The Faeces Of Cattle With False Positive Reactions In Serological Tests For Brucellosis In Ireland, Don O'Grady, Kevin Kenny, Seamus Power, John Egan, Fergus Ryan
Articles
Intestinal infection by Yersinia enterocolitica serotype O:9 (YeO9) in cattle has been linked to false positive serological reactivity (FPSR) in diagnostic tests for brucellosis. Although eradicated in Ireland, brucellosis monitoring still identifies seropositive animals, usually one or two (termed singletons) per herd, which are classed as FPSR. To investigate a link between FPSR and YeO9, faeces and blood were collected from singleton FPSR cattle, and from companion animals, in eight selected herds with more than one FPSR animal, for YeO9 culture and Brucella serology. YeO9 was isolated from 76/474 (16%) FPSR singletons in 309 herds, but not from any of …

Why Human Pain Can’T Tell Us Whether Fish Feel Pain, Victoria A. Braithwaite, Paula Droege
Animal Sentience
In his target article, Key (2016) reviews the neuroanatomy of human pain and uses what is known about human pain to argue that fish cannot experience pain. We provide three reasons why the conclusions reached by Key are unsupported. They consider (i) why it is not sufficient to conclude that only human neural structures can process conscious pain, (ii) why an understanding of pain in humans and non-human animals needs to be based within a framework of consciousness, and (iii) evidence already exists that fish treated with noxious stimuli lose the ability to perform normal behaviours: This was a behavioral …

Although Key (2016) argues that mammals feel pain and fish do not, from an invertebrate perspective, it is obvious that the pain experience is shared by animals from a number of different animal groups.

Do fish consciously feel pain? Addressing this question, Key (2016) asks whether the neural mechanisms underlying conscious pain reports in humans can be identified in fish. This strategy fails in three ways. First, non-mammalian consciousness — if it exists — may depend on different mechanisms. Second, accumulating neurophysiological and behavioural evidence, evolutionary considerations, and emerging Bayesian brain theories suggest that if fish can feel at all, they can feel pain. Finally, the qualitative nature of pain and suffering obliges us, via the precautionary principle, to accommodate the possibility of its existence where doubt remains.

The target article by Key (2016) examines whether fish have brain structures capable of mediating pain perception and consciousness, functions known to depend on the neocortex in humans. He concludes, as others have concluded (Rose 2002, 2007; Rose et al. 2014), that such functions are impossible for fish brains. This conclusion has been met with hypothetical assertions by others to the effect that functions of pain and consciousness may well be possible through unknown alternate neural processes. Key's argument would be bolstered by consideration of other neurological as well as behavioral evidence, which shows that sharks and ray are fishes …
