Description:
Pro rok 2016 se evropským pavoukem roku stal křižák Cyclosa conica. Po morfologické stránce je tento druh nezaměnitelný díky přítomnosti hrbolku na zadním konci hřbetu zadečku. Jeho kolová síť je vybavena vertikálním stabilimentem se zapředenými zbytky kořisti či detritu. Pavouk na kořist číhá uprostřed stabilimenta. Při ohrožení je schopen na síti vibrovat tak, že se pro predátora stane takřka nedetekovatelným., The araneid Cyclosa conica was chosen as European Spider of the Year for 2016. Morphologically the spider is characterised by a single tubercle on the hind part of the dorsal abdomen. Its web carries a vertical stabilimentum with remnants of prey and other detritus. The spider waits for its prey in the middle of the stabilimentum. When disturbed, it vibrates on the web, so it becomes almost undetectable., and Milan Řezáč.

Description:
This paper focuses on the issue of surveying older people. Increasing interest in the issue of ageing and old age has been accompanied by infrequent debate on the methodological pitfalls that might influence research into this specific, albeit very heterogeneous population. Interviewers routinely complete post-interview questions that provide important information on such criteria as respondent difficulty in answering the questions posed. This article examines such difficulty in terms of interviewer and respondent characteristics. It investigates three potential explanations of why interviewers judge an interview as difficult: (1) interviewer characteristics (age and gender), (2) socio-demographic characteristics of the respondent and (3) respondents’ sense of well-being. The data used in this study were obtained from four surveys conducted with older people in the Czech Republic between 2007 and 2011. These surveys explored ageing and old age. The findings show the crucial importance of respondents’ sense of well-being and level of education. No interviewer age or gender effects were observed., Marcela Petrová Kafková., and Obsahuje bibliografii
