Influence of nutritional supplements on microbiological composition of raw sheep milk
The aim of this study is to examine the effect of plant fat sources in sheep feed on somatic cells and the total number of microorganisms in raw milk samples obtained from 210 sheep, breed Pramenka in Una-Sana Canton. The research was conducted in three periods: winter, spring and summer. The herd was divided into experimental and control groups of sheep. In the experimental groups of sheep in each period of the study, omega-3 supplements were added to the diet, namely extruded flaxseed in the amount of 3.5%. The influence of added omega-3 supplements on the microbiological parameters of raw sheep milk, which was milked from experimental and control groups of sheep every fifteen days of the experiment in all periods of the study, was examined. Analysis of variance (ANOVA) found that during the winter and summer feeding period there is a statistically very significant influence of both experimental factors (treatment and period) on the total number of microorganisms and somatic cells in raw sheep milk (p <0.001). In the spring diet in somatic cells, factor treatment did not show a statistically significant effect (ns)
FOOD COMPOSITION OF GRAYLING Thymallus thymallus L., FROM THE RIVER KRUŠNICA
Sportskoribolovnom tehnikom lovljen je lipljen (Thymallus thymallus) na rijeci Krušnici. Ukupno je ulovljeno i analizirano 118 primjeraka. Ciljevi ovog istraživanja bili su dobiti podatke o ishrani ove vrste riba u prirodnim uvjetima sredine te utvrditi sastav sadržaja probavila.
Utvrđeno je da se lipljen iz rijeke Krušnice dominantno se hrani svojtama iz skupine Amphipoda i Ephemeroptera, dok najveći broj svojti pripada skupini Diptera. Sekundarnu ishranu čine Trichoptera sa Hydropsyche sp. kao dominantnijom svojtom, zatim Gastropoda sa dominacijom Valvata sp., Coleoptera i Formicidae. Lipljen se povremeno hrani svojtama iz skupina Isopoda, Hirudinea, Plecoptera, Oligochaeta, Heteroptera, Aranea, Lepidoptera, Hydracarina i Hymenoptera kao i biljnim detritusom.Total of 118 specimens of grayling (Thymallus thymallus) is caught with sport fishing techniques in the river Krušnica.

Grayling occasionally consume Isopoda, Hirudinea, Plecoptera, Oligochaeta, Heteroptera, Aranea, Lepidoptera, Hydracarina and Hymenoptera, as well as plant detritus
THE EFFECT OF TEMPERATURE CHANGE ON ERYTHROCYTE PROFILE OF Carassius gibelio
Istraživanje promjene temperature vode na eritrocitni profil provedeno je na jedinkama babuške (Carassius gibelio) s područja Bardače (BiH). Istraživanjem je obuhvaćeno trideset osam jedinki koje su bile podijeljene u dva akvarija, prilagođene na eksperimentalne uvjete, a potom podvrgnute različitom temperaturnom režimu. Kontrolna grupa jedinki imala je konstantnu temperaturu vode 10ºC, dok je kod tretirane grupe jedinki temperatura vode postupno povećana na 20ºC u periodu od tri dana. Provedena analiza eritrocitnog profila koji obuhvaća: broj eritrocita, koncentraciju hemoglobina, hematokrit, MCV, MCH i MCHC, pokazuje da jedinke koje su izlagane povećanju temperature su imale značajno veće vrijednosti broja eritrocita i hematokrita, dok su jedinke kontrolne grupe imale veće vrijednosti MCH i MCHC.A research on the effect of water temperature change on erythrocyte profile was conducted on Prussian carp (Carassius gibelio) from the Bardača area (BiH). The study included 38 individuals which were divided into two aquaria, adapted to experimental conditions and then subjected to different temperature regime. The control group had constant water temperature of 10ºC, while for treated fish water temperature was gradually increased to 20ºC for three days. Conducted analysis of erythrocyte profile, which includes erythrocyte count, hemoglobin concentration, packed cell volume, MCV, MCH and MCHC showed that individuals exposed to temperature increase had significantly higher values of erythrocyte count and packed cell volume, while control individuals had higher values of MCH and MCHC
Dendroflora Gradskog parka u Bihaću
U radu su prikazani rezultati istraživanja dendroflore Gradskog parka na području grada Bihaća, koji je smješten u sjeverozapadnom dijelu Bosne i Hercegovine, podno planina Plješevice i Grmeč te brda Debeljača. Kroz njega protječu rijeka Una te njeni pritoci Klokot i Privilica. Tijekom florističkog
istraživanja koje je provedeno na obuhvatnom području Gradskog parka u Bihaću, tijekom 2016. godine, zabilježeno je 80 svojti iz 30 porodica, s ukupno 663 jedinke. U parku dominiraju kritosjemenjače (66 svojti; 83 %), među kojima su dvosupnice (78; 97 %), u većoj mjeri zastupljenije nego jednosupnice (2; 3 %). Golosjemenjače su zastupljene s 14 svojti (17 %). S najvećim brojem vrsta ističe se porodica Rosaceae (10 svojti; 13 %) od ukupno 80 svojti. U pogledu habitusa (Erhardt et al., 2002.) dominiraju stabla (45 svojti; 56 %), potom slijede grmovi (32 svojte; 40 %), zatim penjačice (2 svojte; 3 %) i puzavice (1 svojta; 1 %). Listopadne svojte (60; 75 %) su zastupljenije od vazdazelenih (19; 24 %) i zimzelenih (1; 1 %). Najbrojnija svojta u parku je hibridna platana (Platanus x hispanica Münch) sa 115 jedinki. Prema geografskom podrijetlu alohtone svojte (42; 52 %) su zastupljenije od autohtonih (35; 44 %) i hibrida (3; 4 %). Od 42 determinirane alohtone svojte u invazivne spadaju tri (7 %), dok u egzote spada 39 svojti (93 %). Od 80 zabilježenih svojti, u kultivare spada 15 svojti (19 %), a u hibride tri svojte (4 %). U pogledu krajobraznih vrijednosti Gradski park u Bihaću, koji je izgrađen 1888. godine, veoma je bogat dendrološkim svojtama. Neke od njih potječu iz vremena podizanja parka. Navedeni objekt se ubraja u ljepše bosansko-hercegovačke parkove. Međutim potrebna mu je dodatna revitalizacija. Drveće i grmlje uglavnom ima dobre funkcionalne, estetske i oblikovne karakteristike. Parkovna infrastruktura je u vrlo dobrom stanju
An assessment of regulation, education practices and socio-economic perceptions of non-native aquatic species in the Balkans
Alongside climate change, the introduction of non-native species (NNS) is widely recognized as one of the main threats to aquatic biodiversity and human wellbeing. Non-native species and biodiversity are generally low priority issues on the political agendas of many countries, particularly in European countries outside the European Union (EU). The objectives and tasks of this study were to address the policy regulation, education level, education practices, and socioeconomic perceptions of NNS in the Balkans. A questionnaire-based survey was conducted in Albania, Bosnia and Herzegovina, Montenegro, North Macedonia and Turkey (Balkan EU candidate and potential candidate members), in Croatia and Greece (Balkan EU Member States) and Italy (non-Balkan EU Member State). The EU Alien Regulation (1143/2014) concerning NNS is implemented in EU Member States and Montenegro, whereas Albania, Bosnia and Herzegovina and Turkey have not reported specific policy regulations for NNS. Permanent monitoring programmes specifically designed for NNS have not yet been established in the EU Member States. Most countries tackle the issue of NNS through educational activities as part of specific projects. Education level is indicative of the implementation of NNS policy regulation, and efforts are needed for the proper development of relative study programmes. Public awareness and educational preparedness concerning NNS in the Balkans were identified as poor. Strong programmes for management and education should be developed to increase public awareness to prevent further biodiversity losses in the Balkan region

Private and professional life of female employees and their efects on mental health and the right to maternity leave
Usklađivanje privatnog života koji uključuje prije svega majčinstvo, brigu o djeci, kući i brojne druge obveze, i profesionalnog života koji obuhvaća obrazovanje, zapošljavanje, usavršavanje i posvećenost poslu, predstavlja iznimno složen problem s kojim se susreću žene na području rada i radnih odnosa. U današnje vrijeme žene su postale dvostruko ili višestruko opterećene. Pred njih se stavlja svojevrstan izbor između privatnog i profesionalnog života te ih se izlaže životnim izborima i izazovima koji nisu svojstveni muškarcima. Stoga žene radnice sve češće koriste minimum rodiljnog dopusta, a brigu o djeci, obitelji i domu prepuštaju drugim osobama ili ustanovama samo kako bi zadržale posao i omogućile profesionalno usavršavanje i napredovanje. Zbog konstantne izloženosti pritiscima i očekivanjima kako na planu privatnog, tako i na planu profesionalnog života istovremeno, kod žena radnica mogu se razviti određeni poremećaji i stanja koja u značajnoj mjeri mogu utjecati na njihovo mentalno zdravlje. Važeći propisi u Bosni i Hercegovini pružaju minimum prava, ali nedovoljno za uspostavljanje adekvatnog balansa između privatnog i profesionalnog života žena radnica.Bringing into harmony the private life, above all motherhood, care of children, home, and numerous other obligations, and professional life which includes education, employment, further training and dedication to work, pose extremely complex demands on employed women. Women today are doubly or triply burdened. Often they are faced with a choice between private and professional life and challenges that are not typical for men. Some of the consequences are that women take a minimum maternity leave and then have to delegate the care for children, family and home to other persons or to institutions just to keep their job, have time for professional development and achieve promotion at work. The constant pressures both in their private and professional life may lead to certain disorders and conditions that can affect their mental health. The current legislature in Bosnia and Herzegovina offer minimum of rights, quite insufficient for attaining a satisfactory balance between private and professional life of employed women
