Croatian bibliometric analysis, 2000-2007

To develop search filters and retrieve information estimating the Croatian scientific output (SO) focusing on Public Health (PH) and Preventive Medicine (PM) in MEDLINE. A PubMed search of the MEDLINE database was performed to retrieve articles added to this database between 2000 and 2007. Search filters inspired by previous strategies were applied involving 'geographical', 'place of publication', 'subject' and 'language of publication' aspects. An evaluation of the geographical filter performance was done and sensitivity and specificity were calculated. There were obtained publications in several languages, originated in Croatia, published in Croatia and/or abroad. The Croatian SO in the field of PH-PM was obtained for the same period of time by combining search filters. The evaluation of the filter performance showed sensitivity 95.56% and specificity 100%. The filters constructed permitted the retrieval of the Croatian eight years research output. Increased tendency was observed in the global SO evolution and in the PH-PM area as well. The main languages of publication were English and Croatian. This study is a contribution to research in the field of scientific documentation and further analysis is recommended in constructing and developing search filters to retrieve and focus on specific information.     

Diversity,knowledge and spatial distribution of the vascular flora of Croatia

The Balkan Peninsula is recognized as an important centre of plant diversity. Despite the fact that Croatia contains more than 50% of all Balkan species of vascular flora, the knowledge of the spatial distribution, α-diversity and relation to the conservation efforts have never been summarized and presented. A spatial analysis was performed on several data-sets containing a number of records and a number of species per grid cell. Results show that the Croatian flora consists of 4507 species and 1159 subspecies. The residuals around the linear regression used as a measure of the species richness indicate that Croatia had the highest residual value among the 40 European countries sampled and highest stress on the biodiversity value of the Apennine, the Iberian and the Balkan peninsulas. On the basis of half a million findings and their spatial distributions, we observed that within one grid cell (35 km²) 542 species could be expected. A number of records based on the herbarium specimens, literature and field observation and related spatial distribution were discussed. The spatial distribution of α-diversity indicates that the national hot spots were more consistent with the important plant areas network than with the network of officially protected areas.     

Epidemiological patterns of tuberculosis in Croatia in the period 1996-2005

The last comprehensive publication on tuberculosis in Croatia and the earliest impact of war, besides the yearly routine reports, was done in 1996 in Croatian. We were, therefore, interested to explore incidence trends and to highlight the early post-war tuberculosis epidemiological patterns in the next ten years period (1996-2005). A retrospective analysis of epidemiological data on all registered tuberculosis cases in Croatia searching the databases of 21 Croatian Public Health Institutes and the National Tuberculosis Registry was made. During the study period, the total tuberculosis incidence rates in Croatia dropped from 45 to 25.8/100 000 inhabitants. The average highest age-specific rates were recorded in the age group > or = 65 years being in decrease in all age groups. Paediatric cases (0-14 years) represented 4.5% of all cases. Tuberculosis cases among males were recorded in 64% cases, and 83.6% were indigenous population. Tuberculosis was bacteriologically confirmed in 67.7% cases. A low proportion of drug resistance (3.3%) was recorded. During 1985-2005, 56 tuberculosis cases among 242 AIDS cases were reported. Tuberculosis mortality showed a decreasing trend (p < 0.001). However, tuberculosis has still had the highest mortality rates among infectious diseases in Croatia. Despite the War chain of events and tuberculosis programmatic changes, tuberculosis incidence rates in Croatia have been decreasing but they are still far away from national target, incidence rate of 10/100 000 declared in 1998 and much higher than in European Union and Western Europe. Tuberculosis among children, resistance to tuberculosis drugs and HIV prevalence, significant problems in many European countries, have not caused problems in tuberculosis control in Croatia. This favourable epidemiological situation must be kept and improved through strengthened tuberculosis control measures.     

Steppe-like grassland as a refuge of the wild edible and medicinal plant species in anthropogenic landscape in northeastern Croatia

Habitat fragmentation and modification have been recognized as the most serious threats to biodiversity. In Croatia, the intensive human activities resulted in the landscape transformation, reduction of grassland areas and loss of species number. Increasingly threatened are the wild edible and medicinal plants which contribute remarkably to the biodiversity of different grassland types. In northeastern Croatia, one of the last remnants of the steppe-like grassland remained preserved in a very complex anthropogenic landscape. We examined the diversity of vascular plants occurring on this small habitat patch. Among the relatively high number of plant taxa (in a total of 177) found during the two years of investigations, most could be used both for human nutrition (28 taxa), and for the treatment of a wide range of diseases (60 taxa), while some taxa have nutritional value for livestock (17 taxa). All 23 recorded taxa with edible and medicinal properties are threatened in Croatia, 21 are threatened across Europe, and two are Red Listed taxa. Our results showed that small and isolated steppe-like grassland represents an important refuge for variety of valuable plant species in intensively used landscapes. Accordingly, such small habitats should be, at least locally, effectively protected.     

Land Tenure and Naming Systems in Aboriginal Australia

Naming systems play a prominent role in discussions of land tenure by Aboriginal people. Reference to one area of land and its owners is most commonly in terms of name ‘X’, whereas reference to another area of land and its owners is most commonly made in terms of name ‘Y’. Much of the analytical literature examines how these names refer to groups of people. There is considerable dispute as to whether the reference of these names suffices to determine disjoint groupings of owners that can be described by the term ‘clan’. This paper proposes that the analysis of linkages between names and areas of land should have priority over the analysis of linkages between names and groups of people. The evidence shows that the attachment of names to areas of land is more stable and consistent than their attachment to groups of people. There are differences in the ways that names attach to the landscape, and these differences are significant—they determine whether or not more than one name from the same system may be attached to an area of land. This paper focuses on two areas of Australia: the northern Kakadu‐Oenpelli area and the Timber Creek area (both in the Northern Territory). It shows that naming systems identify disjunctive areas of land as the targets for claims of primary ownership in both areas. These disjunctive areas may reasonably be described with the translation term ‘estates’. In the northern Kakadu‐Oenpelli area, corresponding to these estates, there are disjunctive groupings of owners, which may be termed ‘clans’. However, groupings of owners are not clearly disjunctive in the Timber Creek area, and there is little motivation for using the term ‘clan’. This paper proposes that this difference reflects a general pattern in Aboriginal Australia, with naming systems stably and consistently identifying ‘estates’ across much of the continent. They do not identify ‘clans’ with equivalent stability and consistency.     

On German-Croatian and Italian-Croatian language contact

Croatia has always been a multilingual environment. The influence of German and Italian was empowered through direct political influence. During the second part of the 18th and in the 19th century native speakers of German and Italian used Croatian as a second language carrying out their duties at work. This bilingualism can tentatively be referred to as bureaucratic bilingualism. Native Croatian speakers used Italian and German as a second language in certain social areas. Such bilingualism can tentatively be called civic bilingualism. It can be assumed that starting with the 1960s civic German and Italian bilingualism no longer existed. Language contact within the daily life results in German and Italian loan words in Croatian which are still actively present and used in daily communication.     

Croatian national reference Y-STR haplotype database

A reference Y-chromosome short tandem repeat (STR) haplotype database is needed for Y-STR match interpretation as well as for national and regional characterization of populations. The aim of this study was to create a comprehensive Y-STR haplotype database of the Croatian contemporary population and to analyze substructure between the five Croatian regions. We carried out a statistical analysis of the data from previously performed genetic analyses collected during routine forensic work by the Forensic Science Centre "Ivan Vu?eti?". A total of 1,100 unrelated men from eastern, western, northern, southern and central Croatia were selected for the purpose of this study. Y-STRs were typed using the AmpFISTR Yfiler PCR amplification kit. Analysis of molecular variance calculated with the Y chromosome haplotype reference database online analysis tool included 16 population samples with 20,247 haplotypes. A total of 947 haplotypes were recorded, 848 of which were unique (89.5%). Haplotype diversity was 0.998, with the most frequent haplotype found in 9 of 1,100 men (0.82%). Locus diversity varied from 0.266 for DYS392 to 0.868 for DYS385. Discrimination capacity was 86.1%. Our results suggested high level of similarity among regional subpopulations within Croatia, except for mildly different southern Croatia. Relative resemblance was found with Bosnia and Herzegovina and Serbia. Whit Atheys' Haplogroup Predictor was used to estimate the frequencies of Y-chromosome haplogroups. I2a, R1a, E1b1b and R1b haplogroups were most frequent in all Croatian regions. These results are important in forensics and contribute to the population genetics and genetic background of the contemporary Croatian population.     

Quantifying Medicinal Plant Knowledge among Non–Specialist Antanosy Villagers in Southern Madagascar

Quantifying Medicinal Plant Knowledge among Non–Specialist Antanosy Villagers in Southern Madagascar. Medicinal plant knowledge among non–specialist Antanosy villagers of southeastern Madagascar was investigated in a two–stage study. First, free–listing was used to collect the names of medicinal plants most familiar to local people. Data were organized by habitat and frequency into a short list of the 42 most frequently listed plants by habitat. A second group of interviewees were asked to name health conditions that could be treated with plants on the short list. Age, gender, and dwelling proximity to the forest were tested across the general habitat in which medicinal plants were found: in or near the village, in disturbed buffer areas between the village and the forest, or in the forest itself. Neither age nor gender was significant in free–listing. Naming health conditions treated with specific plants showed that knowledge increases with age and that for all but the oldest age group, women knew more plant uses than men. Women knew more plants from the village and buffer areas, and fewer from the forest than men. The proximity of the home to the forest had no influence on medicinal plant knowledge. The non–specialists interviewed named an average of 14 medicinal plants and most knew an average of 37 uses for 9 of the 42 most common medicinal plants. The most common conditions for people knew of plant treatments were stomach ache, babies’ fevers, and several unlisted conditions. Both exotic and endemic plant species were known to the non–specialists indicating that medicinal plant knowledge is being sustained and adapted to changes affecting both the people and their environment.     

The Croatian Health Survey--SF-36: I. General quality of life assessment

The objective of the Croatian Health Survey was the assessment of population health related quality of life in the transitional environment of Croatia. Health status measures incorporate dimensions such as physical, psychological, and social functioning, role performance and perception of wellbeing. In order to assess health status, "The medical outcome study 36-item short-form health survey (SF-36) model" was used. A total sample of 5048 inhabitants (1983 males and 3065 females), 18 years and over, represents approximately 1% of the general population of Croatia. Mean scores were as follows: physical functioning (PF) 69.94, role-physical (RP) 63.01, bodily pain (BP) 64.51, general health (GH) 53.40, vitality (VT) 51.85, social functioning (SF) 72.96, role-emotional (RE) 72.42, mental health (MH) 61.71 and health transition (HT) 44.79. Results of the SF-36 health survey in Croatia are very much like the results in other European countries with indication that general quality of life is lower in Croatia.     

An evaluation of floristic diversity in Medvednica Nature Park (northwestern Croatia)

Abstract

Mount Medvednica (northwestern Croatia), mostly consisting of slates and marls, rises to the north, above the Croatian capital of Zagreb, from 300 to 1,035 m a.s.l. A floristic research was carried out in the area of Medvednica Nature Park, which consists mainly of the western part of the mountain. On the whole, 1,352 taxa of vascular plants were recorded from all sources (field observations, literature and herbaria). Out of these, 48 taxa are strictly protected, 228 are protected, 67 taxa are considered threatened according to the IUCN categories, and 9 taxa are endemic for the Croatian flora. The life-form analysis of the investigated flora shows the predominance of hemicryptophytes, followed by therophytes and geophytes, while the chorological analysis has evidenced the prevalence of Euro-Asiatic, South European and cosmopolite geographical groups. The biological/chorological cross-spectrum was laid out by considering the percent of every life-form for each geographical element. In order to evaluate the floristic richness of the studied area, the α-index was calculated and then compared with the α-indices of similar regions in Croatia and several European countries. A floristic diversity map of Medvednica Nature Park is presented here for the first time.     

Croatian Muslims--immigrant community of indigenous Europeans

Subject of this paper is muslim population in Croatia. Its unique position as community of muslim immigrants with indigenous European origin give us plenty of research opportunities. Long history of contacts between muslims and christians on Croatian-Bosnian border evolved in many ways and resulted with today's reality that muslims are part of Croatian society. In modern age, since austrian occupation of Bosnia in 1878. bosnian muslims came to Croatia as workers, refugees, members of state apparatus, students etc. Their descendants are now Croatian citizens in third and fourth generation. Muslims managed to establish formal islamic community. On the personal level, they mix their feeling of belonging with feeling of origin. They act as equal part of Croatian society on whole range of social levels.     

Extinction of Fen and Bog Plants and their Habitats in Croatia

Although the fens and bogs of Croatia have already been acknowledged as the nation’s most endangered habitats by Croatia’s National Strategy on Biodiversity Protection, the situation continues to become worse rather than better. Fens and bogs are still rapidly deteriorating and even disappearing. A primary factor appears to be changes in climate since original formation of these peatlands, particularly in recent times. This results in progressive changes in vegetation and finally overgrowth of these habitats by forest vegetation. In many cases human activities, whether directly or indirectly, intentionally or unintentionally, have also led to destruction of such habitats. Looking at all mire types as a whole, acidophilous mires are now nearly extinct in Croatia. Basophilous fens are endangered but not critically so. This is because alkaline waters and associated mineral deposits are relatively widespread through Croatia. Some species have already disappeared from the Croatian flora. The status of other mire plant species is doubtful because there are no records for them in recent decades, while it seems very likely that some of the known surviving species could be lost from Croatia in the near future.     

Plant species diversity of Adriatic islands: An introductory survey

Abstract

The European Mediterranean region is one of the world's major centres of biodiversity. Research on plant species diversity in this region has neglected the area along the eastern part of the Adriatic basin in comparison to the other Mediterranean areas. The main aim of this study was to focus on this neglected area, by supplying data which is at present lacking in order to discuss the species-area relationship (SAR), floristic richness and endemism of the Adriatic islands and coast. Floristic data for 106 Croatian islands collected by different authors were integrated, systematised and presented in a form usable by other researchers worldwide. The Power (Arrhenius) function was used for modelling (by non-linear regression) the SAR. Residuals around the regression curve (as indicators of floristic diversity without the influence of island area) were calculated for each island. The proportion of endemics in the total island flora varies from 0% up to 28.6%, and 17.5% for narrow endemics. Floristic richness of the broader region was estimated (on the basis of SAR extrapolation) on 1807 species for all Croatian islands, and on 2797 species for the entire Mediterranean area in Croatia.     

Current status of iodine intake in Croatia--the results of 2009 survey

In 1996, due to persistence of mild to moderate iodine deficiency, new law on obligatory salt iodination with 25 mg of potassium iodide (KI) per kg of salt was implemented in Croatia. Along with a new law, a new program for monitoring of iodine prophylaxis was implemented. Investigations of goiter and iodine intake performed in 2002, demonstrated sufficient iodine intake in Croatia with overall median of urinary iodine concentration (UIC) for schoolchildren in Croatia of 140 microg/L. In 2002, thyroid volumes (TV) measured by ultrasound in schoolchildren from all four geographic regions of Croatia were for the first time within the normal range according to ICCIDD reference values. Nowadays, Croatia is internationally recognized as iodine sufficient country. The aim of the present study was to assess current status of iodine intake in Croatia. The investigation was carried out in 2009. A total of 386 schoolchildren aged 7-10 years from all four major geographic regions of Croatia, 103 euthyroid pregnant women and 36 women of child-bearing age from Zagreb, the capital, were included in the survey. Urinary iodine concentration (UIC) was measured in all participants. Thyroid volumes were measured by ultrasound in schoolchildren from the capital of Zagreb (N = 101) and the village of Rude (N = 56). In the time period 2002-2009, the content of KI was analyzed in 384 salt samples from Croatian salt plants and samples of imported salt. An overall median UIC for schoolchildren in Croatia was 248 microg/L. Median UIC in pregnant women was 159 microg/L, with 50% of samples below and under 150 microg/L. Median UIC in women of child-bearing age was 136 microg/L. Thyroid volumes in schoolchildren were within the normal range according to the new reference values. Mean value of KI/kg of salt in samples from Croatian salt plants was 25.5 mg/kg and 24.9 mg/kg in samples of imported salt. A total of 72/384 (18.8%) of salt samples didn't corresponded to the Croatian law on obligatory salt iodination. Presented data indicate sufficient iodine intake of the Croatian population. Current medians of UIC in schoolchildren in Croatia are significantly higher than medians measured in 2002. This indicates that other potential sources of iodine are present in Croatian diet that may contribute to overall iodine intake. Due to rising medians of UIC in schoolchildren in Croatia, it is important to conduct nutrition studies to identify potential sources of "silent prophylaxis" in order to avoid iodine excess.     

Bioarchaeological research in Croatia--a historical review

The study of human skeletal remains from archaeological sites gives us the opportunity to answer important questions about the lifestyle of past populations. The discipline that studies human skeletal remains is known as bioarchaeology. This paper provides a historical review of bioarchaeological research in Croatia. It is based on the available published material that analyzes human skeletal remains from archaeological sites located on the Croatian territory covering time span from the Neolithic period to the late Middle Ages.     

Five-years cumulative incidence of alcohol consumption in Croatian adult population: the CroHort study

Alcohol consumption is traditionally part of most human cultures, and with the onset of industrial revolution it was recognized as a health and social problem. The aim of this article is to investigate cumulative incidence of alcohol consumption in Croatia. Data were obtained from the Croatian Adult health Survey in 2003 followed by 2008. The cohort consisted of 3229 participants. Questions regarding alcohol consumption were calculated into two factors describing existence or non-existence of risk behavior. Results revealed higher incidence of risk alcohol consumption in man than in women and highest in the 35-65, age group. Due to the some study limitations results might be underestimated. Present problem of alcohol is alarming, even more so, in women's population it might be only the tip of the iceberg. Cultural and regional differences should be taken into account when educational programs are constructed, especially due to the different type of alcohol consumed.     

Drug use among Croatian students

The subject of this study was to determine the frequency of drug use and attitudes toward drug use in Croatian high school students. The study was carried out in a middle-class high school in Zagreb. Out of 273 students who participated in an anonymous, self-report, 23-item questionnaire, 69 reported that they had at least once used drugs. The most frequently used drug was cannabis. While one third of students have been offered drugs, even 41% of the students would have take the drug if it becomes available. It can be concluded that the drugs appear to be highly available among Croatian students. According to our results, even more stronger increase in the number of drug users in Croatia could be expected.     

Epidemiology of HIV infection and AIDS in Croatia--an overview

This article presents an overview of HIV/AIDS epidemiology and surveillance in Croatia 20 years after the first documented case of AIDS in the country. Here we describe strategies employed for HIV/AIDS surveillance in Croatia as well as preliminary results of HIV seroprevalence among most-at-risk populations (MARPs) research conducted by the Infectious Diseases Epidemiology Service at the Croatian National Institute of Public Health (CNIPH). Croatia has a low incidence and prevalence of HIV and AIDS. At the end of 2005, there were 553 documented cases of HIV infection, 239 of which progressed to AIDS. In Croatia, AIDS is being registered within MARPs only and dominantly among men who have sex with men (MSM). AIDS patients and HIV infected persons are found in all parts of the country. Crude prevalence of HIV among MARPs was found to be 0.9%. It is necessary to continue with current prevention and control measures in the country, and to create a culture of awareness and precaution, a strategy that has proven effective in reducing risk of HIV infection.     

Family-group names for termites (Isoptera), redux

Forty-eight family-group names are identified for insects among the Isoptera (termites), representing a nearly 19% increase since the last compilation less than 10 years ago. Accordingly, these names are newly catalogued, including various updates from the original summary. The name Reticulitermitidae is recognized as a nomen nudum while Caatingatermitinae is newly considered a nomen invalidum, and neither is available in zoological nomenclature. A catalogue of the suprafamilial names for Isoptera is appended. The name Xylophagodea is formally proposed for the Isoptera + Cryptocercidae clade.     

A spatial analysis of the ecology and morphology of cicadas in the Pauropsalta annulata species complex (Hemiptera: Cicadidae)

The cicada Pauropsalta annulata Goding & Froggatt, 1904 comprises several distinct song types across its known distribution in eastern Australia, with these songs being statistically distinguishable from one another. Here we use spatial analysis of adult morphology and plant species associations to test further the hypothesis that P. annulata song types represent a complex of cryptic species. To structure this investigation we contrast different approaches and expectations given under the framework of ecological speciation with those of the recognition concept of species. Plotting the geographical distributions of these cicadas revealed that each of the P. annulata song types have independent geographical distributions, with relatively small areas of overlap. ‘Predicted distribution’ modelling revealed that the distribution of each song type forms a unique climatic envelope, which suggests that abiotic factors (rather than interactions among the cicadas themselves) influence the geographical representation of the different song types. One song type has consistent differences in male genitalia, and female ovipositor length differs significantly among three of the other song types. Each song type is strongly associated with a small number of tree species, and these associations are maintained in areas of sympatry. The spatial comparisons made in this study suggest that the P. annulata song types investigated actually represent three species. One of these species is represented by two of the song types originally recognized, and these appear to intergrade in sympatry, and thus represent subspecies. The spatial consistency of the plant associations and morphology exhibited by these (sub)species is significant because it represents an ecological measure of species stability. © 2010 The Linnean Society of London, Biological Journal of the Linnean Society, 2010, 101 , 553–565.
