Asi 70 % dosud zkoumaných vyšších rostlin žije v mykorhizní symbióze s půdními houbami. Wood wide web – síť mycelia sdílených symbiotických hub – umožňuje např. parazitování nezelených rostlin na okolních fotosyntetizujících dřevinách či propojení dřevin a vřesovcovitých keříků. Myceliální sítě tak udržují variabilitu a produktivitu ekosystémů a rostliny si přes ně podle potřeby posílají energii ve formě uhlíkatých produktů fotosyntézy. and About 70 % of higher plants studied so far live in mycorrhiza symbiosis with soil fungi. The wood wide web – a network of symbiotic fungus mycelia enables e.g. non-green plants to parasite on neighbouring woody plants with photosynthesis ability or co-existence of woody plants and Ericaceae shrubs. Nets of mycelia thus conserve the variability and productivity of ecosystems. Plants can share energy through them in the form of photosynthesis carbon products.
The article is conceived as a contribution to a critical reading of opinion data and the presentation of ISSP modules on Work Orientations from 1997 and 2005 in the Czech Republic. In the first part, some methodological problems regarding the inspection of work and job values are presented using examples drawn from previous research. In the second part, the framework of systemic transition is set up and hypotheses are presented regarding work values and attitudes from the perspective of gender and age, education and occupation. In the third part, a comparison is made of people's expectations regarding their work and jobs with their perceived fulfilment. In the fourth part, we consider the perceived location of workers between the distant worlds of family and firms and inspect factors of work and job satisfaction. In conclusion, we discuss the role of subjective perceptions in the economy and the question of a 'true' change in values during the transition.
