THE EXPECTED DEMOGRAPHIC INFLUENCES ON THE PROVISION OF EDUCATION SERVICES IN THE NEIGHBOURHOODS OF RIGA
2020
This paper discusses the spatial extent of population change and provides new insights into the relationships between demographic characteristics and the provision of education services in urban neighbourhoods of Riga. Thus, our empirical evidence confirms that the provision of social infrastructure is fundamentally dependent on the nature of demographic processes. The aim of this paper is twofold: to explore the spatial extent of changes in the number of pre-school and school-aged children in Riga, and to assess how the demographic change of particular age cohorts are associated with the provision of educational establishments at the neighbourhood level. Using available statistics and base…
Author Correction: Evaluation of three methods for biomass estimation in small invertebrates, using three large disparate parasite species as model o…
2018
Invertebrate biomass is considered one of the main factors driving processes in ecosystems. It can be measured directly, primarily by weighing individuals, but more often indirect estimators are used. We developed two indirect and non-destructive approaches to estimate biomass of small invertebrates in a simple manner. The first one was based on clay modelling and the second one was based on image analysis implemented with open-source software. Furthermore, we tested the accuracy of the widely used geometric approximation method (third method). We applied these three different methods to three morphologically disparate model species, an acanthocephalan worm, a crustacean and a flatworm. To …
