A Brief Review Of Morphological Variation In Natrix Tessellata In Israel: Between Sides, Among Individuals, Between Sexes, And Among Regions, Yehudah Leopold Werner, Tal Shapira
Turkish Journal of Zoology
After introducing the distribution and biology of Natrix tessellata in Israel, on the southern edge of its range, we address its intraspecific variation from the literature and examination of 262 museum specimens. Head pholidosis showed no significant directional asymmetry, but asymmetry in infralabial plates was significantly correlated with frequency of injured tails. Variation in body size showed no clear seasonal growth, presumably due to climatic fluctuations. The variation in number of ventrals (in males, 159-173, mode 165) was not geographical. Females attained 750-800 mm (head and body; mode 600-650) and males 700-750 (mode 500-600) mm. Females had significantly greater relative …

The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
The Effects Of Invasion By Reed Canarygrass (Phalaris Arundinacea) On Avian Communities And Nesting Success In Minnesota Wetlands, Emily J. Hutchins
All Graduate Theses, Dissertations, and Other Capstone Projects
Invasive plants are a primary contributor to loss of biodiversity worldwide. In southern Minnesota, many wetlands have been invaded by reed canarygrass (Phalaris arundinacea). The current perception among ecologists and resource managers is that these wetlands are of little value to wildlife, yet little is known about the effects on birds of the widespread conversion of diverse wetlands to apparent monocultures of P. arundinacea. The purpose of this study was to determine the effects of P. arundinaceamediated changes in the wetland plant community on avian communities and nesting success. During 2006 and 2007, I studied four diverse sedge wetlands paired …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson
Open Access Theses & Dissertations
The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …

Conditions for in vitro maturation (IVM) of primary oocytes without conventionally used fetal calf serum and hormones were optimized in order to reduce the cost of laboratory produced buffalo embryos. Comparisons were made between oocyte recovery methods (aspiration vs. slicing) and IVM in medium 199 (static culture method vs. flux culture method) supplemented with 4-5 × 106 granulosa cells mL-1 that contained either estrus buffalo serum (EBS) or fetal calf serum (FCS). Recovery methods were compared according to yield, i.e. cumulus oocyte complexes per ovary (COCs/ovary), the expansion rate (% of COCs that expanded), and nuclear maturation rate (% of …

This experiment was carried out on 200 White Koluda geese, 1 day old, randomly divided into 2 groups with 50 males and 50 females in each group. From the first day until week 13, birds from the control groups were fed basic feeds; in the experimental groups, feed was supplemented with 0.3 mg/kg of selenium and 100 mg/kg of vitamin E. Later on, all birds were fed for 1 week with 160 g of oat grain and 250 g of ground cereals per day, then with oat grain ad libitum. The body weight of each bird was measured individually on …
