Amount of food supplied to nestlings by their parents is considered to affect the development of nestling physiological condition. In this study we supplied parental Great Tits Parus major with extra food, larvae of Tenebrio molitor, put into feeders close to nest-boxes, assuming that this should facilitate parental care and, as a consequence, nestling nutrition. The following nestling characteristics measured 13 days after hatching were analysed: body mass, haematocrit, blood concentrations of haemoglobin, glucose and triglycerides, heterophil-to-lymphocyte ratio (H/L), and patagium swelling after PHA injection. Nestlings from extra food broods were significantly heavier than control ones. They also had lower H/L, which indicated lower stress. No other variable was significantly affected by the experiment. Possibly, the rainy weather and non-restrictive natural trophic conditions during the experiment caused weakening of the net benefits from extra food.

Background. Volleyball is a team game belonging to a group of sports disciplines that involve indirect fighting. Adequate energy coverage in athletes is a crucial issue. It depends primarily on the type, intensity and duration of physical activity related to the sports discipline practiced and to the training cycle duration. The average energy requirement in sportsmen is 50% higher than that of adults. Objective. The aim of the study was to characterize the mode of nutrition, including dietary supplements and to assess somatic indices in female volleyball players of the AZS Bialystok team. Material and methods. The study involved 17 women. Research tools included a questionnaire consisting of 24-hour recall, a questionnaire survey concerning supplement intake and body composition analysis performed using a bioimpedance analyzer InBody 220. Results. Data analysis indicates that the anthropometric characteristics and body composition of the AZS Bialystok players meet the recommendations associated with the somatic features in volleyball. Daily diet of the volleyball players were of low-energy with regard to the recommendations for physically active people, with very low supply of carbohydrates and dietary fiber, excessive proportion of saturated fatty acids and dietary cholesterol, and too low content of monounsaturated and polyunsaturated fatty acids. Supply of vitamins and minerals was found to be alarmingly low, especially of iron and calcium; diet supplementation was insufficient. No significant abnormalities were noted in body composition of the study athletes. However, they are recommended to increase muscle mass and slightly reduce body fat. Conclusions. Results of diet evaluation show the need for education in the field of nutrition and the necessity of further research into dietary habits among sportsmen.

The relation between age, body parameters and the stopover behaviour of a small, short-distance, migratory bird during the season of autumn (August–October) was studied. Capture-recapture data of 1018 first-year and 89 adult European Robins migrating through central Poland (“Kaliszany” ringing station, 21°48’E, 51°05’N) in autumn between 1997 and 2005 were analysed. Body mass, length of wing and tail of young Robins caught and stayed at the stopover site showed significant seasonal variation. Immature Robins made longer stopovers (median = 4 days, 1–41) in the area than older ones (median = 3 days, 1–32). The stopover duration decreased continuously during the season. However, body mass changes at the staging site was not related to the age of birds. The birds migrating in the second half of autumn (late September–October) period accumulated fat faster than birds migrating in the early season. Our analyses confirmed that late migrants stayed for shorter stopovers and gained more body mass than early migrating birds due to a shift in migration strategy as an adaptation to time stress.

The parameters of length–weight relations for Anatolian khramulya, Capoeta tinca (Heckel, 1843) from 10 inland bodies of water of the Samsun Province, Northern Turkey were presented. The b values of the length–weight relations ranged from 2.5444 to 3.3517. For nine freshwater resources in Samsun, this study is the first reference on length–weight relation of Capoeta tinca.

Effects of heavy seed crop (mainly oak mast) in year 2003 and 2004 (no seed crops) on small mammal communities in three isolated stands of broad leaved lowland forests (area 60–280 ha) with different management were studied in southern Moravia in three sites: (1) close-to-nature not managed floodplain forest – Ulmeto–Fraxinetum carpineum (FF), (2) managed forest – Carpineto-Quercetum acerosum (MF), (3) pheasantry – Ulmeto-Fraxinetum carpineum, Saliceto- Alnetum and Carpineto-Quercetum acerosum, with a considerable number of biotopes including open areas (PH). We presumed the influence of seed production on mammal species, especially granivorous rodents. In the most numerous species (Apodemus flavicollis (Mel.), A. sylvaticus (L.) and Myodes glareolus (Pallas)) the demographic parameters (abundance, sex ratio), body mass, and body length were compared between populations in 2003 and 2004 in each stand. Animals were trapped in snap mousetraps laid out in lines. In 2003 reproduction of both Apodemus sp. Was extended to November in contrast to 2004, when it ceased already in the end of summer. Individual body mass of animals were significantly higher in 2004 vs. 2003 in all three species (A. flavicollis, P = 0.01; A. sylvaticus, P <0.01 and Myodes glareolus, P <0.05) but body length was higher only in case of A. sylvaticus (P <0.01). The forest stands under study in an intensively managed agroecosystem in southern Moravia play an important role as a refuge for small mammals.
