Unusual findings of softmouth trout Salmo obtusirostris (Actinopteri: Salmonidae) in the marine environment along the middle Eastern Adriatic coast as a consequence of extreme weather events

The discovery of individuals of softmouth trout Salmo obtusirostris in the marine environment has been recorded several times in the period from 2015 to the present day in the wider area of the Neretva River delta and southern Adriatic coast. Although this phenomenon appears to be happening more frequently along the Adriatic coast, scientific reports regarding family Salmonidae species found in the marine environment are still very rare in the eastern Adriatic, especially for the softmouth trout. The findings reported here represent the first marine records of this endemic freshwater species. An increasing frequency of these findings may indicate that a higher number of individuals are ending up in the coastal environment during heavy storm events or other unusual hydrologic occurrence. Extreme weather conditions have become more frequent in recent years, mainly as a result of climate change and have led to unexpected phenomena and impacts on nature. The long-term effects on fish and community structure of rivers flowing into the sea require further research, as these weather-induced situations can be expected to become more common. Further investigation into the physiological costs and population consequences of these unusual ecological findings is warranted

LIFE HISTORY TRAITS OF NERETVA ROACH Rutilus basak (Heckel, 1843) (Pisces, Cyprinidae): BIOLOGICAL AND ECOLOGICAL CONTRIBUTION FOR BIODIVERSITY CONSERVATION OF FRESHWATER FISH

U radu je dan pregled relevantne znanstvene literature o trenutnom statusu, distribuciji, staništu, ekološkim svojstvima, strukturi populacije i prijetnjama neretvanskoj plotici (Basak) Rutilus basak (Heckel, 1843). Navedena vrsta nastanjuje ograničeno područje jadranskog riječnog sliva u Republici Hrvatskoj i Bosni i Hercegovini. Najveće prijetnje vrsti su gubitci staništa uzrokovani značajnim hidrološkim promjenama vodnog režima na njenom distributivnom području te introdukcija alohtonih ribljih vrsta. Ipak, R. basak je prilično rasprostranjena vrsta koju se često nalazi u izobilju. Informacije objedinjene u radu bi mogle unaprijediti znanja o navedenoj vrsti.This paper is a review of the relevant scientific literature on the present status, distribution, habitat, ecological traits, population structure and threats of Neretva roach Rutilus basak (Heckel, 1843). The species inhabits a restricted area of the Adriatic Sea watershed in Croatia and Bosnia and Herzegovina. The major threats are habitat loss caused by significant hydrological changes in the water regime in the area of distribution and theintroduction of non-indigenous species. Still, R. basak is quite widespread and often abundant. Information brought together in this study will improve our knowledge about this species

NATURA 2000 U BOSNI I HERCEGOVINI: DOKLE SMO STIGLI?

Rad razmatra problematiku ispunjavanja obaveza Bosne i Hercegovine u oblasti zaštite prirode na njenomevropskom putu. Naročita pažnja pridaje se analizi rezultata četiri do sada sprovedena projektakoja se tiču procesa uspostavljanja evropske ekološke mreže Natura 2000 u BiH. Na bazi svih relevantnihnaučnih i stručnih podataka rad daje reviziju referentne liste vrsta sa Aneksa II Direktive o staništima iAneksa I Direktive o pticama, kao i reviziju liste staništa sa Aneksa I Direktive o staništima, značajnih zaizdvajanje budućih Natura 2000 područja na teritoriji države. Biljna vrsta Himantoglossum adriaticumBaumann, značajna za Evropsku uniju, prikazuje se kao nova za Bosnu i Hercegovinu. Predložena revidiranareferentna lista vrsta broji 238 vrsta od čega 11 nije pominjano ni u jednoj dosadašnjoj referentnojlisti, a neki ranije razmatrani taksoni i stanišni tipovi su izbrisani sa liste. Na kraju, rad ustanovljava nekenedostatke prijedloga mreže Natura 2000 u BiH i daje glavne smjernice kako bi ovaj važan proces trebaobiti nastavljen
