Vadföldi növények szerepe a gímszarvas táplálékában Valkón.
Red deer is an emblematic species of Hungarian game management. In the maintenance of good quality deer populations establishment of a network of food plots in the
hunting area can be a helpful tool. Since cultivation of game plots can be very expensive, information on the utilisation of the plots and the forages provided there is needed. In our study we investigated the utilisation of four game plots by red deer in Valkó from May 2008 to February 2009. Our study aim was to determine the intensity of area use by deer on food plots and reveal the proportion of food plot forage in the diet of red deer individuals visiting the food plot. We carried out seasonal faeces counts and microhistological faeces analyses. We found that red deer appear in food plots in
every season, although there were differences in the deer dropping density between different game plots. The proportion of rye (Secale cereale) available in all food plots sampled and that of maize (Zea mays) provided as winter supplementary food was very low in the diet of deer. Generally, both components represented less than 10 % of the individual diet. We suggest that in the diet of red deer food plot forage - or at least rye - should not be fundamental. Nevertheless, we have no information on the potential positive physiological impacts of consumed food plot forage. We recommend cultivating more various plant food resources in game plots to make those plots more attractive to deer. We also propose establish and maintain diverse understory in the forest because it usually solves as basic food supply for deer
Butterfly and skipper records from Lebanon (Lepidoptera: Papilionoidea)
Eighty-five specimens of 30 papilionoid species have been collected in Lebanon during entomological expeditions launched in 2015 and 2016 by the joint project of the Hungarian Natural History Museum and the Holy Spirit University of Kaslik. Th e collecting sites and events are listed, and the species annotated. With 23 figures
Habitat selection of Eurasian woodcock Scolopax rusticola during the spring migration period in Hungary
To establish a decent regulation of the hunting of woodcock in Hungary, a monitoring
programme started in 2009 at a national scale. More than 900 participating observers collect data of
woodcock during synchronized censuses each spring and in autumn to have basic knowledge of
woodcock presence and abundance in the country. Data collecting locations were selected by the
observers themselves based on their former experiences, which was primarily influenced by the
former knowledge about habitat use of woodcock. Their selection of sites could primarily be
influenced by the former knowledge about habitat use of woodcock. This situation offers an
opportunity to evaluate this choice of habitats. In this study we investigated the habitat selection of
woodcock during spring migration and we tested whether the preceding designation of observation
points reflects enough knowledge about their habitat preferences.
We used four year spring observation data of the Hungarian woodcock monitoring programme based
on synchronized censuses. In order to evaluate the choice of the observers, observation points were
buffered with a radius of 874 meters - 2* radius of a 60 ha circle which is known to be used by
woodcock individuals in the evening roding period. We intersected the buffers with the Corine
Landcover map, and we compared their composition with the composition of buffers of randomly
generated points.To evaluate the choice of the birds, correlation between landcover types preferred or
avoided by the observers and the detections of woodcock was tested using the nonparametric
Spearman correlation. In the case of forests we performed an additional analysis: We classified the
buffers using 3 categories of their forest cover rates (0-45% OPEN, 45-77% MID, 77-100%
FORESTED). We took 50 random samples of each forest cover rate class per year and we tested the
differences among them in the number of woodcock detections and the frequencies of positive sites
(where woodcock observation happened).According to our results, the locations of the observation
points might not be resulted by random choice. Most landcover types preferred or avoided are also
correlated with woodcock abundance. However the correlations we have found were weak. The key
element of choice is the presence of forests. The higher rate of broad-leaved forests near the points
can raise, the higher rate of discontinuous urban fabric or non-irrigated arable land can lower
detection probability
DISTRIBUTIONAL RECORDS TO KNOWLEDGE OF MANTIS RELIGIOSA IN THE SĂLAJ-REGION, ROMANIA (MANTODEA)
We provide 17 data of Mantis religiosa (Linnaeus, 1758) originating from the Sălaj-region of
western Transylvania, Romania between 11. August, 2014 and 9. September, 2015. Geographical, spatial
and temporal records are documented for the better knowledge of the species
