First Report Of Gray Whale (Eschrichtius Robustus, Lilljeborg, 1861) Conjoined Twin Calves In The Eastern Pacific Ocean, Elena Tamburin, Erica Carone, Irma Gonzalez Lopez, Felipe Galvan Magaña Jan 2017

First Report Of Gray Whale (Eschrichtius Robustus, Lilljeborg, 1861) Conjoined Twin Calves In The Eastern Pacific Ocean, Elena Tamburin, Erica Carone, Irma Gonzalez Lopez, Felipe Galvan Magaña

Turkish Journal of Zoology

In January 2014, gray whale (Eschrichtius robustus) conjoined twin calves were found dead in Laguna Ojo de Liebre (Scammon's Lagoon), Baja California Sur, Mexico. The thoracopagus (united ventrally at the chest) individuals were conjoined in the thorax region, sharing the navel and genital area, but with two distinct heads and flukes. Although observed in humans and domestic animals, this case is rare among cetaceans. Some conjoined twin cetacean fetuses have previously been reported; however, this is the first report of the congenital anomaly in Eschrichtius robustus.

Mitochondrial Evidence Indicates A Shallow Phylogeographic Structurefor Jaculus Blanfordi (Murray, 1884) Populations (Rodentia: Dipodidae), Ekaterina Melnikova, Morteza Naderi Jan 2017

Mitochondrial Evidence Indicates A Shallow Phylogeographic Structurefor Jaculus Blanfordi (Murray, 1884) Populations (Rodentia: Dipodidae), Ekaterina Melnikova, Morteza Naderi

Turkish Journal of Zoology

Our study was performed on the phylogeographic structure of Blanford's jerboa (Jaculus blanfordi (Murray, 1884)) collected from nine localities in Iran, Turkmenistan, and Uzbekistan and was based on mitochondrial evidence indicating a slight phylogeographic divergence among the populations. We aimed to amplify two frequently used mitochondrial markers, cytochrome b (cyt b) and cytochrome c oxidase subunit I (COI) fragments, from 33 specimens obtained from the abovementioned countries. Our phylogeographic analyses uncovered two distinct groups, thus supporting the presence of two subspecies: J. b. blanfordi in Iran and J. b. turcmenicus in northern Turkmenistan and Uzbekistan. Finally, we discuss the intraspecies …

Mating Behaviour And Its Relationship With Morphological Features In The Millipede Pachyiulus Hungaricus (Karsch, 1881) (Myriapoda, Diplopoda, Julida), Zvezdana Jovanovic, Sofija Pavkovic-Lucic, Bojan Ilic, Vukica Vujic, Boris Dudic, Slobodan Makarov, Luka Lucic, Vladimir Tomic

Turkish Journal of Zoology

Although millipedes (Diplopoda) represent one of the most diverse classes of arthropods, data concerning details of their mating behaviour are very scarce. In this work, we explored mating behaviour of the European millipede Pachyiulus hungaricus under laboratory conditions, and its relationship with the size and shape of certain morphological traits. We conducted 3 types of behavioural tests: a mating arena test, a female choice test, and a male choice test. Premating behaviour was "sequenced" in 5 behavioural steps and, together with the duration of copulation, scored in all mating assays. Males were the more active sex in searching for mates, …

Unusual Winter Zooplankton Bloom In The Open Southern Adriatic Sea, Davor Lucic, Zrinka Ljubesic, Ivana Babic, Suncica Bosak, Ivona Cetinic, Ivica Vilibic, Hrvoje Mihanovic, Marijana Hure, Jakica Njire, Petra Lucic, Petar Kruzic Jan 2017

Unusual Winter Zooplankton Bloom In The Open Southern Adriatic Sea, Davor Lucic, Zrinka Ljubesic, Ivana Babic, Suncica Bosak, Ivona Cetinic, Ivica Vilibic, Hrvoje Mihanovic, Marijana Hure, Jakica Njire, Petra Lucic, Petar Kruzic

Turkish Journal of Zoology

The paper reports an unusual response of the microzooplankton community to oceanographic conditions observed during the winter of 2015 in the open southern Adriatic. Record-breaking nauplii abundance of 13,734 ind. m-3 was sampled for the open southern Adriatic by 50-\mum net sampling. This could be explained by (i) warmer-than-usual surface and intermediate ocean temperatures, (ii) higher precipitation that freshened and widened the surface layer, pushing saline Levantine Intermediate Water below a 400-m depth, and (iii) strong wind episodes that transported nutrients from the coastal zone to the open ocean and induced limited vertical mixing. Neritic tintinnids and viable photoautotrophs well …

Turkish Journal of Zoology

We analyzed variation in the distribution of eastern Hermann's tortoise (Testudo hermanni boettgeri) in a complex landscape consisting of both natural and human-altered habitats in a temperate climate region in Serbia. Our results indicated nonrandom distribution of tortoises within different habitat types with large and medium effect size for year and activity pattern, respectively. Additionally, the tortoises expressed relatively weak preference for habitats modified by human activity (e.g., vineyards, orchards, or gardens). The results suggested that these tortoises preferred some particular habitats more than others when performing specific activities. They also did not exhibit the same distribution pattern among habitats …

A Case Of Limb Regeneration In A Wild Adult Podarcis Lilfordi Lizard, Alex Cortada, Antigoni Kaliontzopoulou, Joana Mendes, Miguel A. Carretero Jan 2017

A Case Of Limb Regeneration In A Wild Adult Podarcis Lilfordi Lizard, Alex Cortada, Antigoni Kaliontzopoulou, Joana Mendes, Miguel A. Carretero

Turkish Journal of Zoology

We report here a case of spontaneous limb regeneration in a wild Podarcis lilfordi lizard from the Balearic Islands. The animal had lost a hind limb, which regenerated posteriorly into a tail-like appendage. Despite not representing a functional regeneration, the growth of this structure after limb amputation suggests that survival of the individual may have been favored by the less restrictive conditions prevailing in insular environments. Nevertheless, such cases are extremely rare in lizards, with no reported cases over the last 60 years.

Comparison Of Two Methods For Sampling Orthopterans In Grassland: Differences In Species Representation And Sex Ratios, Stanislav Rada Jan 2017

Comparison Of Two Methods For Sampling Orthopterans In Grassland: Differences In Species Representation And Sex Ratios, Stanislav Rada

Turkish Journal of Zoology

Orthopterans are convenient indicators for threatened grassland ecosystems. Many sampling methods are known; among them, sweep netting is the most common. This study compares sweep netting with less common pan trapping and quantifies differences in species representation and sex ratio between the two sampling techniques. Sampling took place in the submontane grassland in the northeastern part of the Czech Republic (Central Europe) during July, August, and September 2010. Both sweep netting and pan trapping were used concurrently in 11 meadows. Sampled orthopteran adults were determined to the species level and their sex was noted. Both methods recorded the same pool …

Prolonged Association Between A Pair And A Related Male In Breeding Whooper Swans (Cygnus Cygnus), Krzysztof Dudzik, Michal Polakowski, Michal Ciach Jan 2017

Prolonged Association Between A Pair And A Related Male In Breeding Whooper Swans (Cygnus Cygnus), Krzysztof Dudzik, Michal Polakowski, Michal Ciach

Turkish Journal of Zoology

Waterfowl (Anatidae) are a group of birds in which parental care is performed by both parents (a pair) or, less often, by females only. Alternative social systems in this group have been recorded only occasionally. This paper describes three unusual cases of prolonged association between a pair and an additional male (the offspring or sibling of the primary pair) in breeding Whooper Swans (Cygnus cygnus). In all instances the three birds displayed no antagonistic behaviour towards family members, participated in territorial defence, and bred successfully. These cases are unusual in light of what is currently known about the social system …

What Can Vigilance Tell Us About Fear?, Guy Beauchamp Jan 2017

What Can Vigilance Tell Us About Fear?, Guy Beauchamp

Animal Sentience

Animal vigilance is concerned with the monitoring of potential threats caused by predators and conspecifics. Researchers have argued that threats are part of a landscape of fear tracking the level of risk posed by predators and conspecifics. Vigilance, which is expected to vary with the level of risk, could thus be used as a measure of fear. Here, I explore the relationship between vigilance and fear caused by predators and conspecifics. The joint occurrence of vigilance and other physiological responses to fear, such as increased heart rate and stress hormone release, would bolster the idea that vigilance can be a …

Individual Variation In Fear Behaviour, Rob Found Jan 2017

Individual Variation In Fear Behaviour, Rob Found

Animal Sentience

Individual variation in behaviour adds another layer of complexity to studies of animal responses to fear and risk, but when individual responses are consistent, and correlated with other behaviours, these patterns can provide a structure that furthers our understanding. I interpret Beauchamp’s review of vigilance and fear from the perspective of my own studies of elk personality. Wild elk responses to changing stimuli (benign or aversive) illustrate how personality is a key factor in explaining variation in vigilance and fear behavior. Personality even influences how wildlife can learn to assess risk and adjust their fear responses accordingly.

Considering Side Biases In Vigilance And Fear, Lesley J. Rogers Jan 2017

Considering Side Biases In Vigilance And Fear, Lesley J. Rogers

Animal Sentience

Measures of vigilance and fear might be more consistently associated if side biases are taken into account, because the right side of the brain is specialised to detect predators and to express fear responses. In species with eyes positioned laterally and with relatively small binocular fields, this brain asymmetry is manifested as eye preferences because each eye sends most of its input to be processed in the opposite side of the brain. Hence, responses elicited by stimuli on the animal’s left side are more likely be associated with fear than are responses to the same stimuli on the animal’s right …

The Effect Of Pistacia Terebinthus Extract On Lipid Peroxidation, Glutathione,Protein, And Some Enzyme Activities In Tissues Of Rats Undergoing Oxidative Stress, Semra Türkoğlu, Sai̇t Çeli̇k, Serhat Keser, İsmai̇l Türkoğlu, Ökkeş Yilmaz

Turkish Journal of Zoology

This study measures the effects of Pistacia terebinthus flower extract on the amounts of lipid peroxidation (LPO), total protein, glutathione, and enzyme activities in blood. It also measures the effects of the plant extract on glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) enzyme activities and it arrives at the conclusion that GSH-Px activity significantly increased in the Pistacia terebinthus-hydrogen peroxide group (P < 0.0001) and SOD activity meaningfully increased in the Pistacia terebinthus (P < 0.05) and Pistacia terebinthus-hydrogen peroxide (P < 0.0001) groups. It is also found that P. terebinthus extract has protective effects against LPO exerted in the kidney, brain, and lungs (P < 0.0001). The positive effects of P. terebinthus extract are also found on the levels of glutathione and total protein in all organs, except for the level of glutathione in the spleen and brain, and the increase of glutathione and total protein (P < 0.0001). These results are parallel to the effect of the extract used in this study on the LPO levels in tissues and they show that the plant species used in the study has positive effects on the activities of antioxidant molecules as well as protective effects against LPO.

The Incidence Of Rare Males In Seven Parthenogeneticartemia (Crustacea: Anostraca) Populations, Muhammad Saleem Chang, Alireza Asem, Shichun Sun

Turkish Journal of Zoology

Males that present infrequently in parthenogenetic Artemia are commonly called "rare males". By rearing cloned parthenogenetic Artemia in the laboratory, the frequency of rare males was observed for seven Artemia populations with different ploidy compositions. The results showed that the values of the male:female ratio varied from 0.53:1000 to 1.40:1000 in diploids from different populations, and there were significant differences among populations and clones. No rare males were found in any of the 46 polyploid clones (217,197 individuals) observed.

Cautions About Precautions, Jay R. Stauffer Jr. Jan 2017

Cautions About Precautions, Jay R. Stauffer Jr.

Animal Sentience

Assuming an animal to be sentient in the absence of conclusive evidence to the contrary is an extreme position, hence it should not and could not be the default assumption. Birch explains how the precautionary principle may be used to substantiate decisions to give the animal the benefit of doubt. Although I am reluctant to accept all of his points, Birch has provided an excellent argument for the use of the precautionary principle for the detection of animal sentience. I agree that more research is needed to refine and understand this relationship.
