Five New Records Of Gall Midges (Diptera: Cecidomyiidae) From Iran, Mahmoud Joghataie, Hussein Sadeghi Namaghi, Marcela Skuhrava

Turkish Journal of Zoology

Five gall midge species were identified as new records for the fauna of Iran from the Joghatay region of Razavi Khorasan Province, NE Iran. These species are Campylomyza flavipes Meigen, 1818 (Micromyinae); Micromya lucorum Rondani, 1840 (Micromyinae); Rabdophaga salicis (Schrank, 1803) (Cecidomyiinae); Rhopalomyia efremovi Fedotova, 1999 (Cecidomyiinae); and Rhopalomyia monogynasphaera Fedotova, 1999 (Cecidomyiinae). As many parts of the country have not been studied in terms of Cecidomyiidae fauna, the gall midge fauna of Iran will be increased considerably with further research.

Conservation Of A New Breeding Population Of Caucasian Lynx(Lynx Lynx Dinniki) In Eastern Turkey, Mark Chynoweth, Emrah Çoban, Çağan Şekerci̇oğlu Jan 2015

Conservation Of A New Breeding Population Of Caucasian Lynx(Lynx Lynx Dinniki) In Eastern Turkey, Mark Chynoweth, Emrah Çoban, Çağan Şekerci̇oğlu

Turkish Journal of Zoology

Current data on the distribution and ecology of the Eurasian lynx (Lynx lynx) in Turkey are limited. Furthermore, lynx in the Caucasus region are likely to represent a subspecies of the Eurasian lynx, the Caucasian lynx (L. l. dinniki). Throughout its range, lynx increasingly face threats due to human activity, with habitat loss and prey depletion being of particular concern in eastern Turkey. As part of our camera trapping efforts to monitor large carnivores in the Sarıkamış-Allahuekber National Park and surrounding forests in Kars and Erzurum provinces, eastern Turkey, we have documented a breeding population of Caucasian lynx outside the …

Changes In Abundance And Community Structure Of The Zooplankton Population During The 2008 Mucilage Event In The Northeastern Marmara Sea, Melek İşi̇ni̇bi̇li̇r Okyar, Funda Üstün, Deni̇z Ayşe Orun Jan 2015

Changes In Abundance And Community Structure Of The Zooplankton Population During The 2008 Mucilage Event In The Northeastern Marmara Sea, Melek İşi̇ni̇bi̇li̇r Okyar, Funda Üstün, Deni̇z Ayşe Orun

Turkish Journal of Zoology

The composition and abundance of zooplankton and the corresponding environmental conditions were investigated during the 2008 mucilage event (April-December 2008) in the Marmara Sea. As a result, 46 zooplanktonic taxa were identified. Copepods and cladocerans were generally the most abundant groups. Mnemiopsis leidyi had a significant seasonality, and abundance was related to fluctuations in temperature and salinity. The most important species were Acartia clausi and Penilia avirostris, but these species did not reach their usual autumn maximum. As a result, the mucilage event in 2008 caused significant shifts in zooplankton abundance and community structure in the Marmara Sea.


Sexual Dimorphism In Trachylepis Vittata (Olivier, 1804) (Sauria: Scincidae) In The Zagros Mountains, Western Iran, Nasrullah Rastegar-Pouyani, Razieh Fattahi Jan 2015

Sexual Dimorphism In Trachylepis Vittata (Olivier, 1804) (Sauria: Scincidae) In The Zagros Mountains, Western Iran, Nasrullah Rastegar-Pouyani, Razieh Fattahi

Turkish Journal of Zoology

We describe sexual dimorphism in coloration, size, and shape in 48 specimens (19 males and 29 females) of the bridled skink, Trachylepis vittata (Olivier, 1804), collected from western regions of the Iranian Plateau. For the analyses, we used 29 metric and 9 meristic characters. Our study showed the existence of slight sexual size dimorphism in body and head size between the sexes. Males had significantly smaller heads and narrower bodies than females. Furthermore, males and females were different in the structure of the cloaca. The possible scenarios behind sexual dimorphism in this lizard are discussed.

Two-Fold Increase In White Stork (Ciconia Ciconia) Population In Lithuania: A Consequence Of Changing Agriculture?, Daiva Vaitkuviene, Mindaugas Dagys

Turkish Journal of Zoology

A countrywide White Stork (Ciconia ciconia) nest census was carried out in Lithuania in 2009 and 2010 by over 20 observers using standardised equipment and methods. The census revealed that the White Stork population has doubled since the previous census in 1994, possibly due to favourable changes in farming practices, with birds increasingly settling on the overhead electricity line poles and gradually abandoning nests in trees. In total, 21,192 White Stork nests were recorded, of which 18,782 (81.4%) were occupied by breeding birds, compared to 9400 occupied nests recorded in 1994. The mean density of occupied nests in the country …

Population Level Responses To Direct Application Liming In Gyrinophilus Porphyriticus, Shelby Renea Timm

Theses, Dissertations and Capstones

Direct application liming (DAL) has been used to neutralize acidified streams to restore aquatic biota. This mitigation technique has been used globally for decades, yet little data exist on its effects on amphibian populations. My study investigated the effects of liming on amphibians by measuring variability in life histories of larval Gyrinophilus porphyriticus. I collected larvae from six streams in the Monongahela National Forest, West Virginia. I examined the effects of DAL on age structure, and I failed to detect a treatment effect. I used ANCOVAs to examine differences in body condition, body size, and gape size. I observed that …


Sampling Considerations For Amphibian Surveys: Evaluating Risks Of Committing Type I And Type Ii Errors, Kelli Marie Herrick Jan 2015

Sampling Considerations For Amphibian Surveys: Evaluating Risks Of Committing Type I And Type Ii Errors, Kelli Marie Herrick

Theses, Dissertations and Capstones

Global amphibian declines pose a major threat to the world’s biodiversity. We examined the observation bias associated with volunteer based anuran surveys, such as the North American Amphibian Monitoring Protocol (NAAMP). We followed NAAMP protocol to examine if variation in the persons (1-3) in an observer unit affected observer error. We hypothesized that observation units with multiple observers have less observer bias and would better report anuran assemblages compared to single observers. Larger observer units had fewer incidences of false positive observations. Additionally, we attempted to determine which sampling method for the eastern hellbender (Cryptobranchus a. alleganiensis) had the highest …


Functional Studies Of Ptchd3 During Spermatogensis, Shaimar R. González Morales Jan 2015

Functional Studies Of Ptchd3 During Spermatogensis, Shaimar R. González Morales

Theses, Dissertations and Capstones

Paracrine factor Desert hedgehog (Dhh) is essential for mouse spermatogenesis. However, the specific receptor of Dhh during spermatogenesis is unknown. This study aims to test the hypothesis that Ptchd3, a male germ cell-specific gene acts as a receptor for Dhh in spermatogenesis. In this study, a transgenic mouse model with Ptchd3 gene deletion was first successfully established. Then, in vivo fertility assay and in vitro analysis were performed on Ptchd3 null mutant male mice. The data obtained from the in vivo fertility experiments indicates that there is no statistical significance in offspring litter number (p-value 0.7973) and litter size (p-value …

Effects Of Roads And Trails On Peaks Of Otter Salamander (Plethodon Hubrichti) And Eastern Red-Backed Salamander (Plethodon Cinereus) Movement Behavior, Cory Benjamin Goff

Theses, Dissertations and Capstones

Habitat fragmentation negatively affects movement and dispersal of wildlife by altering useable space and creating barriers. The objective of this study was to assess impacts of fragmentation by roads and trails on the movement behavior of two terrestrial, woodland salamander species. I evaluated whether proximity to roads and trails affected the movement behavior of two species: the Peaks of Otter Salamander (Plethodon hubrichti), a species of special concern, and the Eastern Red-backed Salamander (Plethodon cinereus). I examined movement behavior in three treatments: paved roads, gravel roads and hiking trails. I compared treatments to controls located at least 200m from treatment …


Monitoring The Land Cover Change In The Historic Range Of Cambarus Veteranus In West Virginia Using A 1973-2013 Landsat Time Series, Emma Martha Arneson Jan 2015

Monitoring The Land Cover Change In The Historic Range Of Cambarus Veteranus In West Virginia Using A 1973-2013 Landsat Time Series, Emma Martha Arneson

Theses, Dissertations and Capstones

The crayfish Cambarus veteranus is near extinction in its historic range of the Upper Guyandotte River watershed. The biggest threats to C. veteranus are mining and road construction. Mining has been a continuous activity in the southern coalfields where the crayfish has historically been found, yet little is known about how much land cover change the practice has done to the region. Crayfish act as important organisms within aquatic ecosystems and without them, those systems are often degraded. Quantifying the change in land cover is important to understanding threats to C. veteranus for future protection of the crayfish and its …

Brood Provisioning And Nest Survival Of Ardea Herodias (Great Blue Heron) In Maine, Margaret M. Meserve Auclair, Kathryn A. Ono, Noah G. Perlut

Marine Sciences Student Publications

From 1983–2009, the number of coastal breeding pairs of Ardea herodias (Great Blue Heron [GBHE]) in Maine declined by 64%, and the number of occupied islands on which these birds bred declined by 40%. The Maine Department of Inland Fisheries and Wildlife listed the GBHE as a species of special concern in 2007, and expanded its annual monitoring to include inland colonies in 2009. To assess regional demographic differences, we compared the relationship between brood provisioning and nest survival of GBHEs in 1 coastal and 1 inland colony. In terms of brood-provisioning within the 2 colonies, the inland colony had …


Father Convict Cichlids Bite Intruders More Often In Hot Temperatures, Jesse L. Heckendorf Jan 2015

Father Convict Cichlids Bite Intruders More Often In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have evolved to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a male convict cichlid’s aggression toward caring for his offspring when an intruder is introduced. Male convict cichlids attack more in warmer water.

Turkish Journal of Zoology

Determination of attractive and avoidance behavior of Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is very important in the concomitant use of Beauveria bassiana for control of Aphis fabae (Hemiptera: Aphididae). We investigated the olfactory response of the predatory insect H. variegata when receiving odors pertaining to Aphis fabae infected by B. bassiana EUT116 at 0-, 24-, 48-, and 72-h intervals in a Y-tube olfactometer set-up. Behavioral assays were conducted to assess the ability of adult H. variegata to avoid A. fabae infected with B. bassiana conidia on plants. In these experiments, H. variegata exhibited significant attraction towards the control when the …


Using Body Condition Index Can Be An Unreliable Indicator Of Fitness: A Case Of Sand Lizard Lacerta Agilis Linnaeus, 1758 (Sauria: Lacertidae), Krzysztof Dudek, Zofia Sajkowska, Monika Gawalek, Anna Ekner-Grzyb Jan 2015

Using Body Condition Index Can Be An Unreliable Indicator Of Fitness: A Case Of Sand Lizard Lacerta Agilis Linnaeus, 1758 (Sauria: Lacertidae), Krzysztof Dudek, Zofia Sajkowska, Monika Gawalek, Anna Ekner-Grzyb

Turkish Journal of Zoology

In ecological and morphological studies, researchers often use body condition index as a measure of an individual's fitness. Our research shows that body condition index may be an unreliable method for this purpose, because changes in lizards' body proportions are not stable during their lifetime. Results obtained from a Polish population of the sand lizard (Lacerta agilis) show that the body length increases faster than the body mass, meaning that the correlation between these 2 parameters is not linear. Herpetologists frequently use the body condition index to compare the fitness of lizards of different ages. Our study demonstrates that this …

White-Tailed Deer (Odocoileus Virginianus) Fawn Risk From Gray Wolf (Canis Lupus) Predation During Summer, L. David Mech, Aaron Morris, Shannon M. Barber-Meyer

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Little is known about how often various prey animals are at risk of predation by Gray Wolves (Canis lupus). We used a system to monitor the presence during the day of two radio-collared Gray Wolves within 2 km of a radio-collared White-tailed Deer (Odocoileus virginianus) with a fawn or fawns in August 2013 in the Superior National Forest of northeastern Minnesota. We concluded that the fawn or fawns were at risk of predation by at least one wolf at least daily.
