Abstract

The present phytosociological study of the eastern Adriatic coastal salt-marsh at Blato, Croatia, is based on the Braun-Blanquet approach. Five plant associations were recorded in the area: Juncetum maritimo-acuti, Puccinellio festuciformis-Sarcocornietum fruticosae, Scirpetum maritimi, Enteromorpho intestinalidis-Ruppietum maritimae and Cressetum creticae. The association Cressetum creticae was found for the first time in Croatia as well as on the eastern Adriatic coast. This therophytic and halo-nitrophilous association shows a monospecific or paucispecific character and occupies the most haline and the driest parts of the salt-marsh. The association develops during the summer on silty clay substrates with organic matter derived from the decay of plants of the neighboring communities. According to key soil factor analysis no differences of grain size of the soils among the associations were found, while regarding electrical conductivity, Cl- and Na+ concentrations were higher in the Cressetum creticae than in any of the others associations. The particular original features of the site regarding its flora and vegetation would justify some measures of protection and management.

Abstract

There are 40 regularly occurring raptor species in Croatia (diurnal raptors and owls), but only for two species (Griffon Vulture Gyps fulvus and Eleonora’s Falcon F. eleonorae) long-term monitoring (more than 10 years) of significant parts (i.e. > 80%) of their national population has been implemented. For 23 species (58%), the coverage of monitoring is limited to several locations (often within borders of given protected area), involving small percentage of national population or/and has started recently. Therefore, they do not satisfy the main purpose of national monitoring programmes, i.e. to draw conclusions about the trend of the species’ national population and to support the decision-making process about conservation measures to be applied. Besides the Institute of Ornithology and several ornithological NGOs, which are recognized as main actors for the implementation of raptors monitoring, the State Institute for Nature Protection (SINP) is setting up a framework for the nationwide bird monitoring complying with the legal provisions of the EU Birds Directive and the Natura 2000 network. The highest priority is to improve the coordination between state institutions, scientific and non-governmental organizations involved in raptor conservation with the final aim to develop a national raptor conservation strategy that sets priority target species and standardized monitoring systems

Abstract

Introduction

This study reports about antenatal characteristics of Roma minority population. The study was designed to investigate data about health behaviours known to be associated with reproductive outcomes of Roma women that have very good living conditions and relatively high resource availability.

Methods

A retrospective study included 204 Roma and 408 non-Roma hospitalised singleton births that occurred in the Maternity Ward of the General Hospital Virovitica in the period from 1991 to 2010. Data about women’s age, marital status, smoking, reproductive health (abortions, delivery), antenatal care, perinatal complications and gestational age were taken from hospital records and analysed.

Results

Roma women were averagely more than three years younger than non-Roma women, only 10.8% were married. Smoking was more frequent. The average number of births of Roma and non-Roma women was similar, averagely two children per woman. The rate of induced abortions in the Roma women was higher, while the frequency of spontaneous abortions was equal. Inadequate antenatal care of Roma women was associated with two times higher incidence of perinatal complications. A higher frequency of deliveries at home without professional assistance in Roma pregnancy resulted in lower perinatal outcomes. It was confirmed that Roma mothers give birth earlier (38+6 vs. 39+4 weeks) and have a higher incidence of premature births (9.3% vs. 2.2%).

Conclusions

In the comparison of antenatal parameters between the two researched groups, poorer prenatal outcomes in the Roma population were found, despite full integration and considerable improvement in living standards of this ethnic Roma population.

Abstract

The Ladislavci Field (oil and gas reservoirs) is located 40 km from the city of Osijek, Croatia. The oil reservoir is in structural-stratigraphic trap and Miocene rocks of the Vukovar formation (informally named as El, F1a and F1b). The shallower gas reservoir is of Pliocene age, i.e. part of the Osijek sandstones (informally named as B). The oil reservoirs consist of limestones, breccias and conglomerates, and gas is accumulated in sandstones. Using neural networks, it was possible to interpret applicability of neural algorithm in well log analyses, and using neural model, it was possible to predict reservoir without or with small number of log data. Neural networks are trained on the data from two wells (A and B), collected from the interval starting with border of Sarmatian/ Lower Pannonian (EL marker Rs7) to the well’s bottom. The inputs were data from spontaneous potential (SP) and resistivity (R16 and R64) logs. They were used for neural training and validation as well as for final prediction of lithological composition in the analysed field. The multilayer perceptron (MLP) network had been selected as the most appropriate.

Abstract

Aim: To gain insight into the trend of career choice for family medicine in Croatia in recent years.

Methods: Six surveys were performed in the academic years 2006/07-2011/12 at the University of Zagreb, School of Medicine. Altogether, 1140 6th year students participated. They anonymously completed a questionnaire containing questions on desired future specialisation as well as other selected characteristics (e.g. gender, desired area and place of work, motivation to study medicine, etc.). Binary logistic regression was used to determine unadjusted and adjusted trends.

Results: After adjustment for selected factors, the relationship between observed outcome and the year of observation showed an evident decreasing trend. The odds for intention to specialise in family medicine were in the academic year 2006/2007 1.43-times higher than in the year 2007/2008 (p=0.412), 1.85-times higher than in the year 2008/2009 (p=0.168), 2.38-times higher than in the year 2009/2010 (p=0.051), 2.63-times higher than in the year 2010/2011 (p=0.027) and 3.85-times higher than in the year 2011/2012 (p=0.003).

Conclusions: The results of the present study offer evidence that Croatia is experiencing a constantly decreasing trend of career choice for family medicine in recent years. It is obvious that final year medical students are not very much interested in working as family practitioners. At the same time, demand for family practitioners in Croatia is increasing. Both academic and professional societies have a social responsibility to reorient the health care system and medical curricula towards comprehensive primary health care in which family medicine has a key role.

Nomenclatural-Phytocoenological Analysis of the Association Potentillo Micranthae-Quercetum Petraeae Ass. Nova in Croatia

Phytocoenological traits of forests of sessile oak in the area of Zrinska Gora were investigated in 2009. Phytocoenological research was conducted using a method of the Zürich-Montpellier School. A comparison was made with acido-thermophilic forests of sessile oak from central and north-western Croatia, then from Slovenia and the Mescek Mountains in Hungary.

A statistical comparison was made by entering all the phytocoenological relevés into the Turboveg database. This was followed by a classical synthetic analysis of the phytocoenological relevés and a multivariate analysis using Syntax 2000 software. Average Ellenberg's values were calculated for each relevé with JUICE 6.3 software.

Taking into consideration all the facts, it can be concluded that the newly established association Potentillo micranthae-Quercetum petraeae shows a high degree of independence and differentiation from other similar associations described to date. In relation to others, it is poorer in species, both in terms of the systematic categories to which it belongs and the number of elements from the orders of Fagetalia and Quercetalia pubescentis. Of the species occurring in acidophilic forests of sessile oak, Genista tinctoria, Chamaecytisus hirsutus and Dicranella heteromalla can be considered characteristic species, whereas Galium sylvaticum, Cephalanthera longifolia, Dianthus armeria and Viola alba can be termed differentiating species. The species Potentilla micrantha, Festuca drymeia and Luzula forsteri are very important for the structure, physiognomy and syndynamics of the association.

It is subordinated to the alliance Quercion robori-petraeae, the order Quercetalia robori-petraeae and the class Querco-Fagetea.

Effect of Management Modification on the Coenological Composition of the North Adriatic Pastoral Landscape (Ćićarija, Croatia)

The research aim was to assess the dynamics of the North Adriatic pastoral landscape (Ćićarija, Croatia) with regard to the coenological composition of grassland communities, and, more specifically, to: i) assess the current grassland mosaic from a coenological viewpoint; ii) assess the effects of management abandonment on grassland species composition, also taking into account, as a basis for comparison, data on pastoral communities collected in the past decades. To achieve the research aims, 73 phytosociological relevés were carried out; for each of them field data (altitude, aspect, slope, landform) and information on grassland management were collected. Multivariate analysis of phytosociological relevés led to the identification of four vegetation types (Danthonio-Scorzoneretum villosae, Carici humilis-Centaureetum rupestris, Brachypodium rupestre-dominated stands, and Anthoxantho-Brometum erecti), which were linked to landform and to grassland management. Comparison in terms of social behaviour type composition of the grassland communities surveyed in the present study with the ones surveyed in the past decades, highlighted that the current management (grassland abandonment, as well as low intensity grazing and not periodic mowing) is leading to a percentage loss of pasture and meadow characteristic species, in favour of successional and ruderal ones.
