| This work examined the enzymatic (superoxide dismutase-CuZn SOD, catalase-CAT, glutathione peroxidase-GSHPx, glutathione reductase-GR, and the biotransformation phase II enzyme glutathione-S-transferase-GST) and nonenzymatic (total glutathione-GSH and lipid peroxides-TBARS concentrations) biomarkers of oxidative stress and acetylcholinesterase (AChE) activity in the blood of the grass snake (Natrix natrix L.) during prehibernation and posthibernation. The animals were collected in October (prehibernation) and April (posthibernation) at the nature reserve Obedska Bara (OB) and industrial region Pancevacki Rit (PR) in Serbia. In posthibernation, decreased CAT activity and TBARS concentration in specimens from PR, and decreased GR and AChE activities, and... |

| In order to further studying the relationship between the gastrointestinal endocrine cells and the hibernation of Chinese fire-bellied newt, histological techniques were used in this study to explore the distributed density and morphology of argentaffine cells in the digestive tract during hibernation and non-hibernation. The argentaffine cells could be observed throughout the digestive tract of Chinese fire-bellied newt during hibernation and non-hibernation and mainly distributed in the acinar epithelial cells, epithelial cells and intrinsic membrane. They had appeared in the shape of goblet, pyramid, ellipse, round, cone-shaped, spindle-shaped. The cytoplasm contains secretory granules at the basal regions with spherical nuclei in the basal regions.... |

| By means of radio-thermotelemetry a study was made of the thermoregulatory patterns during hibernation of a common hamster, Cricetus cricetus (L., 1758) under natural conditions. In the euthermic state, body temperature (Tb) fluctuated between 36.4 and 38.6°C with Tb higher than 37.0°C probably indicating activity. The hamster went into deep hibernation 23 times. The entrance into hibernation lasted 20—60 hours, the state of deep hibernation 17—110 hours and the subsequent arousal 3.5—6.5 hours. Both the duration of arousal and of a bout of hibernation seemed to be negatively correlated with Tb. The euthermic interbout state lasted 4—25 hours. The minimum Tb during deep hibernation ranged between 10.0 and 2.6°C. Sixteen bouts of hibernation could be... |

| Malassezia is a genus of medically-important, lipid-dependent yeasts that live on the skin of warmblooded animals. The 17 described species have been documented primarily on humans and domestic animals, but few studies have examined Malassezia species associated with more diverse host groups such as wildlife. While investigating the skin mycobiota of healthy bats, we isolated a Malassezia sp. that exhibited only up to 92 % identity with other known species in the genus for the portion of the DNA sequence of the internal transcribed spacer region that could be confidently aligned. The Malassezia sp. was cultured from the skin of nine species of bats in the subfamily Myotinae; isolates originated from bats sampled in both the eastern and western United... |

| Grapholita molesta (Busck) is one of the major pests of Rosaceae, causing significant damage to buds and fruits. In Southern Brazil, its population density is reduced during Rosaceae dormancy months. The present study evaluated the influence of different photoperiods (L:D) (10:14, 11:13, 12:12, 13:11, 14:10 and 16:8) at 25 ± 1ºC and 60 ± 10% RH on diapause induction of G. molesta eggs, larvae, prepupae, and pupae. The effects of the photoperiod on the life cycle of non-diapausing insects and on the second generation were also assessed. Prepupal diapause was observed only when eggs and neonates (< 12h-old larvae) were exposed to photophases from 10h to 14h long. Development of non-diapausing individuals and those from the second generation tended to be... |
