Caterpillar phenology predicts differences in timing of mountain chickadee breeding in urban and rural habitats
No full textTo ensure the survival of their offspring, birds need to precisely time their reproduction: when offspring have the highest demand for food, food resources should be most abundant. In temperate environments, caterpillars are often a key food source for nestlings, so many insectivorous bird species time their reproduction to correspond to the peak abundance of caterpillars in their habitat. Mountain chickadees (Poecile gambeli) are small songbirds that naturally inhabit coniferous forests, but are also found in urban areas. Reproductive timing of these birds may be altered by urbanization, as mountain chickadees in the city have been shown to breed earlier than those in natural habitat. This study aimed to determine if caterpillar abundance drives reproductive timing of mountain chickadees and if urbanization alters the timing of caterpillar abundance. Birds in both urban and rural habitats were monitored throughout the breeding season. Caterpillar abundance was estimated at each nest location by collecting samples of caterpillar excrement (frass).We found that in both urban and rural habitat, frass mass changed throughout the breeding season, but the date of maximum frass mass occurred about one week earlier in urban habitat. However, in both habitats maximum frass mass occurred when offspring were approximately 11 days old. Our results suggest that mountain chickadees time their reproduction to correspond to caterpillar abundance, and birds in urban environments may be reproducing earlier to correspond with earlier peak caterpillar abundance in the city.Peer reviewedarticlespublishedPoecile gambeliFrassUrbanizationReproductive timingCaterpillarMountain chickade
Introduction
No full textThe political attention for ECEC quality is reflected in several initiatives from the Directorate General for Education and Culture of the European Commission. It was clearly present in the 2011 statement on the importance of early childhood education (European Commission, 2011), as well as in a comprehensive study on competence requirements for the early childhood workforce, commissioned in 2010 to a consortium of the University of East London and Ghent University (Urban, Vandenbroeck, Van Laere, Lazzari & Peeters, 2012). The study consisted of a literature study, a survey on curricula for the different early years professions in fifteen countries and a series of seven in-depth case studies on how these recent challenges are met in diverse contexts. Projects like CoRE, as reported in this book, are exercises in interrogating complex contexts of public policy and professional practice
Urban ‘tourism exploration space’: the example of Łódź
No full textThe author refers to the concept of ‘tourism space’ published earlier, and confronts this notion with a definition of ‘urban space’, bearing in mind that both these ‘spaces’ are subspaces of general ‘geographical space’. Assuming that each is distinguished on the basis of differing criteria, the author believes that the tourism function which gives rise to ‘tourism space’ can develop within ‘urban space’. Further on, the formulation of a precise definition of urban ‘tourism exploration space’ is focused on, which is understood as a personal space of created in the discovery of a city. The conclusion includes three case studies of urban ‘tourism exploration space’ in Łódź: Bidermann family properties, Piotrkowska courtyards and the ‘Green Ring of Tradition and Culture’
Potreba za kompetentnim sustavima: otkrića i preporuke europskog istraživačkog projekta
No full textIstraživači, praktičari i predstavnici obrazovne politike slažu se da kvaliteta predškolskog odgojno-obrazovnog sustava – kao i njezin utjecaj na djecu i obitelji – ovisi o ‘kompetentnom’ stručnom osoblju vrtića.

Urban and Peri-urban Agriculture in Kyiv (Ukraine): "Crisis Induced Strategy" versus Recreational Resource
No full textFor the study 240 Kyiv households with urban and peri-urban agriculture (UPA) have been surveyed in 2005. Quotas were assigned to four different types of plots. A standardized questionnaire was developed to collect data on crop and animal production, inputs, sales of produce for income, importance of the plot for self-sufficiency, recreation and leisure time. A factor analysis is employed to reduce attitudinal data. Based on factor scores a cluster analysis is conducted to segment the respondents into more homogeneous groups and to show multiple purposes of UPA. Four clusters labeled as “Seekers of leisure activities”, “UPA-dependent growers”, “Recreation-oriented growers” and “Little engaged growers” are created. Multiple purposes of UPA are shown by profiling the clusters due to demographic, socioeconomic and other selected characteristics. The results show that depending on the type of plot the importance of UPA shifts from livelihood necessity to recreational resource or combines both.Urban and peri-urban agriculture, livelihood, Ukraine, Farm Management,
Early Childhood in the Global Village: Competent systems for sustainable development
No full textA global consensus is emerging that early childhood services, and the policies to develop them, can only be sustainable and beneficial for all children and all families once we take public responsibility and start building a coherent ‘competent system’ of supports around them. This article looks at what that means in practice in Ireland, based on best current international thinking.Fil: Urban, Mathias. Universidad de Dublin; IrlandaFil: Guevara, Jennifer Luciana.
