White-tailed deer were introduced into the Czech Republic about one hundred years ago. Population numbers have remained stable at low density despite almost no harvesting. This differs from other introductions of this species in Europe. We presumed that one of the possible factors preventing expansion of the white-tailed deer population is lack of high-quality food components in an area overpopulated by sympatric roe, fallow and red deer. We analyzed the WTD winter diet and diets of the other deer species to get information on their feeding strategy during a critical period of a year. We focused primarily on conifer needle consumption, a generally accepted indicator of starvation and on bramble leaves as an indicator of high-quality items. We tested the following hypotheses: (1) If the environment has a limited food supply, the poorest competitors of the four deer species will have the highest proportion of conifer needles in the diet ; (2) the deer will overlap in trophic niches and will share limited nutritious resource (bramble). White-tailed, roe, fallow, and red deer diets were investigated by microscopic analysis of plant remains in their faeces. The volume of bramble decreased in the diet of all four deer species from November to March. The content of conifer needles in the diet of white-tailed and roe deer was negatively correlated with bramble and in spring made up 90 % of their diet volume. On the other hand conifer needles in the diet of red and fallow deer occurred only in January with snow cover. Fallow and red deer started the compensation of winter starvation at least one monthearlier than both roe and white-tailed deer. a high content of conifers in white-tailed deer diet in the second half of the winter fully support the presumption about low nutritional food supply and its diet. It can lead to a markedly impaired condition for white-tailed and roe deer and negatively affect their condition. The dietary overlap of four sympatric deer species was extensive in winter. All species share a limited good quality food supply (bramble) when food is scarce, suggesting that interspecific competition may occur.
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.
Childcare leave schemes are one of the key measures that affect the ability of women and men to balance their work and family lives. Both the length of the parental leave period and the amount of the benefit have the potential to shape the timing of a subsequent birth. Important changes have been introduced into the Czech parental benefit scheme over the last 10 years in terms of both the scheme’s flexibility and the monthly amount of the benefit, which has provided a unique opportunity for studying the links between the institutional conditions of parenthood and the behaviour of real stakeholders. Using data on births from the Czech Statistical Office and the parity-cohort analytical approach, we investigate changes in the spacing of second and third births among women who had their first or second child between 1986 and 2013. The results revealed an increase in the second- and third-birth rate during the second and third year following a delivery, together with a decrease in the second- and third-birth rate during the fourth year and later among mothers exposed to changes in the parental benefit scheme. These changes in reproductive behaviour noticeably coincided with the incentives that have been provided since 2008 by the increased flexibility of the parental leave scheme and the author argues that the option to increase the monthly amount of the parental benefit together with the flexibility of its use has contributed to the closer spacing of births, most notably among more educated women.
