Dispersal of individuals of the flightless grassland ground beetle, Carabus hungaricus (Coleoptera: Carabidae), in three populations and what they tell us about mobility estimates based on mark-recapture

Knowledge of the dispersal ability of endangered species is crucial for developing effective, evidence-based conservation policies. Due to their limited dispersal abilities and specific habitat requirements, insects are among the animals most threatened by habitat fragmentation. We studied three populations of the highly endangered species of ground beetle, Carabus hungaricus, at three sites in Central Europe (Hungary and Czech Republic) using mark-release-recapture (MRR). The total catch of 574 pitfall traps set at the three sites was 6255 individuals. Depending on the site, the percentage recaptured was 13–32%. average and maximum distance moved by individuals of both sexes at each of the sites ranged between 47–132 and 207–1104 m, respectively. The probability of the movements following an inverse power function (IPF) for the two sexes did not differ, but did differ among sites. Probability of dispers- ing for distances >100 m differed by an order of magnitude between sites, most likely because of differences in how the samples were collected. Despite the fact that individual beetles are able to move over distances in the order of kilometres, the high fragmentation of their habitats is likely to prevent them from colonizing most uninhabited habitat patches. Therefore, the conservation of this threatened ground beetle could be improved by adopting and implementing a policy of assisted dispersal. Our results from three study sites also provide an interesting illustration of the variability in the estimates of the probability of dispersal obtained using MRR

Acceptance of the meat of wild ungulates among the hungarian consumers

The culture of game meat cooking in the Hungarian cuisine has very old tradition. In the recent survey we focused on the following species: red deer (Cervus elaphus), fallow deer (Dama dama), roe deer (Capreolus capreolus), mouflon (Ovis musimon) wild boar (Sus scrofa). Our aim was to map the consumers’ requests, the demand as well as the main objectives on the domestic market. The results represent a descriptive picture on the acceptance, rejection, attitudes and preferences concerning the given meat types. Data were collected (n=500) by on-line and paper based questionnaire as well, and were processed by PASW Statistics 18 software. Most of the asked consumers ate already game meat occasionally (all those who have hunter in the family eat at least in every month and more species). Differences were found between the answers of the asked sample population living in urban and in the rural areas. About 90% of the consumers considered game meat as healthy and almost organic food. Those people who have a negative attitude to game meat are vegetarian or refuse consumption due to fear from zoonotic diseases or emotional reasons. The availability of game meats is better year by year, but the answerers judged the fresh and pre-cooled meat more favourable, than the deep frozen ones, and buy the game meat more frequent from hunters, than from supermarkets. By the opinion of the answerers the game meats are expensive meats (compared to the meats of domestic animals). Deer meats were preferred by the value of delight, and the wild boar meat was preferred by the price

Non-destructive structural analysis of the heat conducting path in power electronics and solid state lighting by thermal transient testing

Thermal transient testing is a tool for examining structural details of a heat conducting path composed of heat conduction and heat convection sections. Using the change of inherent heat in electronics, temperature transients provide a characterisation technique where using x-ray or acoustic microscopy would be troublesome and time-consuming. A complete toolkit for the accurate dynamic characterisation of subassemblies and cooling mounts is described in the paper. After giving the theoretical background, it is shown that the methodology can directly generate a valid and detailed structural equivalent from a single transient measurement. The descriptive thermal functions such as time constants and structure functions are demonstrated in practical examples, the capability of the structure functions for validating cooling concepts and detecting assembly problems is shown. Recognising the fact that systems with multiple energy transport such as electric energy converted to heat and light exhibit special features; the concept of structure functions has been modified for applications in solid state lighting.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers
