  The main challenge for mankind has always been to eliminate the borders of its living space, as well as to explore and discover its new faces. Contemporary literature strengthens this postulate. It is the preference of the experts of various fields in spatial analysis is to consider space to be repairable, changeable and organisable. In accordance with this axiom, the five affected countries in the catchment area of the Tisza river (Hungary, Romania, Ukraine, Slovakia and Serbia) worked out an integrated, mutual standpoint to support the problems of the catchment area and to exploit its opportunities with the aim to support transnational cooperation. They laid great emphasis on the existing resources which could become the driving force behind regional development directions. This study contains the summarised outcomes of the TICAD project (SEE/A 638/4.2./X) which was drawn up as a result of cooperation between renowned institutions of the five affected countries within the South East Europe Transnational Cooperation Programme (lead partner: VÁTI, Hungary).

  The aim of our study was to evaluate the quality parameters, porosity and weight loss of eggs deriving from the two most significant ostrich farms in Hungary. Quality parameters included weight, length, width, shape index, egg volume, surface area, circumference and shell volume.  The effect of storage conditions in both farms and the incubation technology on egg weight loss in farm “A” were also examined.  The research objective was to impart a comprehensive knowledge on egg quality parameters of the main ostrich populations in Hungary and to compare the trios and the farms with each other and the international literature. We could reveal significant differences between trios in all egg quality traits. In conclusion, the shorter and the narrower the eggs were, the more spherical shape they had.  Narrower eggs showed smaller surface area, volume, circumference and shell volume and vice versa. Eggs from farm “B” indicated significantly greater width, shape index, surface area, circumference and shell volume than farm “A”. A significant difference was observed in weight loss during storage between the farms.  Weight loss in farm “A” was a multiple of farm “B”. In farm “B” there was a weak, positive correlation between storage period and weight loss (r=0.22, P≤0.05), in farm “A” it was not significant (P=0.52). There was no relationship between the initial egg weight and weight loss either in farm “A” or farm “B” (P=0,21, P=0,69). A slight positive correlation could be noted between egg porosity and weight loss (r=0.24, P≤0.05). Pores count presented here was less than the international results. Poultry eggs contain the most pores at the blunt end, less via the equator and the least at the pointed end. In ostrich egg we found more pores via the equator against the blunt end. To draw more precise conclusions, further investigation should be carried out on porosity. Considering the fact that the length of storage period and the weight loss during incubation are in strict correlation with hatchability, we intend to extend our research aims to these traits.

  The multicoloured Asian ladybird beetle (Harmonia axyridis (Pallas, 1773)), a former successful biological control agent in the USA and Western Europe became an invasive alien species threatening the diversity of native aphidophagous insects through competition and praying, a horticultural pest consuming various fruits and adversely affecting the wine quality and a human nuisance when occurring at high densities in buildings. Due to this dubious fame, attention has been paid to it also at national level which made inevitable to find for it a fitting name in different languages. In some cases and countries a version of the English name has been chosen however, regarding the meaning of this translated term in Hungarian, the try cannot be called fortunate. The objective of this contribution is to stress the function of common animal names in the Hungarian Sprachraum and to find a right and proper alternative with the help of etymology, mythology, classical literature, art (painting) and the experiences of Hungarian fruit and grape growers.

  In this study our aim was to provide a comprihensive overview of the most commonly used methods in molecular genetic studies related to Equus caballus. Thus we are dealing with the D-loop region of mitochondrial DNA, with microsatellites and also with single nucleotid polimorphism as SNP. The advantages and drawbacks of each method were also explored.

  The cultivation of alternative crops has an important role in world agriculture. Their market share is continuously growing in the food industry sector. In the present study, we show the cultivation and breeding perspectives of ornamental and blue corn. There exists possibility to cultivate ornamental corn in Hungary. There are many cultivars of ornamental corn, with various kernel colors, husks, stalks and leave colors. Blue corn is unique among other corns. Blue corn higher in protein, iron and zinc than commercial dent corn. Pests affective ornamental and blue corn are the same as those of other commercial corns. Ornamental and blue corns need to be grown a minimum of 500 m away from commercial yellow dent corn to minimize any cross pollination which may result in off-color kernel. Our aim in the presentation of this review was to broaden Hungarian literature.

  The cluster concept is well defined in the literature, but its agricultural adaptation has not been detailed. A method is needed, which involves 
  experts into the study, who are able to confirm that the modell is correct and help to define the conceptual gaps. The Delphi technique is suitable
  for the task. This is a well-structure, iterative future foresight technique, based on experts opinion about the research topic. The method leads to consensus by all means, but it also can have a negative outcome of the researcher's point of view, that's why we have to formulate scenarios.
  The aim is not statistically significant result, but to build in new ideas into the modell with brainstorming.
