2. State of the art of the marine non-idigenous flora and fauna in SloveniaLovrenc Lipej, Borut Mavrič, Martina Orlando-Bonaca, Alenka Malej, 2012, izvirni znanstveni članek Povzetek: Authors provide the state of knowledge on marine non-indigenous species in waters off Slovenia. According to published records and authors unpublished data at least 15 non-indigenous species were up to date recorded in the Slovenian part of the Adriatic sea. Eleven species were considered as established and four species as casual. The vectors of introduction are various, comprising Lessepsian migration, mariculture and shipping. The majority of non-indigenous taxa were recorded in the mediolittoral belt and coastal lagoons. The low number of non-indigenous species so far recorded in the Slovenian part of the Adriatic sea could be explained by various factors. Among them, the most reasonable are the lack of scientific attention, the small proportion of Slovenian Sea and low winter temperatures, which represents a physiological barrier for the survival of newcomers. The number of recorded species is far from being satisfactory. Therefore, we expect that the list of non-indigenous species will be enlarged in the nearby future.

3. New Mediterranean marine biodiversity records (October 2015)Lovrenc Lipej, Fabio Crocetta, S. Ciriaco, Maria Corsini-Foka, 2015, izvirni znanstveni članek Povzetek: The Collective Article “New Mediterranean Biodiversity Records” of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided per countries, listed according to a Mediterranean west-east geographic position. New biodiversity data are reported for 7 different countries, although one species hereby reported from Malta is overall new for the entire Mediterranean basin, and is presumably present also in Israel and Lebanon (see below in Malta). Italy: the rare native fish Gobius kolombatovici is first reported from the Ionian Sea, whilst the alien jellyfish Rhopilema nomadica and the alien fish Oplegnathus fasciatus are first reported from the entire country. The presence of O. fasciatus from Trieste is concomitantly the first for the entire Adriatic Sea. Finally, the alien bivalve Arcuatula senhousia is hereby first reported from Campania (Tyrrhenian Sea). Tunisia: a bloom of the alien crab Portunus segnis is first reported from the Gulf of Gabes, from where it was considered as casual. Malta: the alien flatworm Maritigrella fuscopunctata is first recorded from the Mediterranean Sea on the basis of 25 specimens. At the same time, web researches held possible unpublished records from Israel and Lebanon. The alien crab P. segnis, already mentioned above, is first formally reported from Malta based on specimens collected in 1972. Concomitantly, the presence of Callinectes sapidus in Maltese waters is excluded since based on misidentifications. Greece: the Atlantic northern brown shrimp Penaeus atzecus, previously known from the Ionian Sea from sporadic records only, is now well established in Greek and international Ionian waters. The alien sea urchin Diadema setosum is reported from the second time from Greece, and its first record date from the country is backdated to 2010 in Rhodes Island. The alien lionfish Pterois miles is first reported from Greece and concomitantly from the entire Aegean Sea. Turkey: the alien rhodophyte Antithamnion hubbsii is first recorded from Turkey and the entire eastern Mediterranean. New distributional data are also offered for the native fishes Alectis alexandrina and Heptranchias perlo. In particular, the former record is constituted by a juvenile of 21.38 mm total length, whilst the latter by a mature male. Cyprus: the rare native cephalopod Macrotritopus defilippi, and the alien crab Atergatis roseus, sea slug Plocamopherus ocellatus and fish Cheilodipterus novemstriatus are first recorded from the entire country. Lebanon: the alien crabs Actaea savignii and Matuta victor, as well as the alien fish Synanceia verrucosa, are first recorded from the entire country. In addition, the first Mediterranean record of A. savignii is backdated to 2006, whilst the high number of M. victor specimens observed in Lebanon first suggest its establishment in the basin. The Atlantic fishes Paranthias furcifer and Seriola fasciata, and the circumtropical Rachycentron canadum, are also first reported from the country. P. furcifer record backdate its presence in the Mediterranean to 2007, whilst S. fasciata records backdate its presence in the eastern Mediterranean to 2005. Finally, two of these latter species have been recently ascribed to alien species, but all the three species may better fit the cryptogenic category, if not a new one.

4. New Mediterranean Biodiversity Records (April 2015)Lovrenc Lipej, Borut Mavrič, A. Zenetos, 2015, izvirni znanstveni članek Povzetek: The Collective Article ‘New Mediterranean Biodiversity Records’ of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of native and alien species respectively. The new records of native fish species include: the slender sunfish Ranzania laevis and the scalloped ribbonfish Zu cristatus in Calabria; the Azores rockling Gaidropsarus granti in Calabria and Sicily; the agujon needlefish Tylosurus acus imperialis in the Northern Aegean; and the amphibious behaviour of Gouania willdenowi in Southern Turkey. As regards molluscs, the interesting findings include Ischnochiton usticensis in Calabria and Thordisa filix in the bay of Piran (Slovenia). The stomatopod Parasquilla ferussaci was collected from Lesvos island (Greece); the isopod Anilocra frontalis was observed parasitizing the alien Pteragogus trispilus in the Rhodes area. The asteroid Tethyaster subinermis and the butterfly ray Gymnura altavela were reported from several localities in the Greek Ionian and Aegean Seas.
The new records of alien species include: the antenna codlet Bregmaceros atlanticus in Saronikos Gulf; three new fish records and two decapods from Egypt; the establishment of the two spot cardinal fish Cheilodipterus novemstriatus and the first record of the Indo-Pacific marble shrimp Saron marmoratus in semi-dark caves along the Lebanese coastline; the finding of Lagocephalus sceleratus, Sargocentron rubrum, Fistularia commersonii and Stephanolepis diaspros around Lipsi island (Aegean Sea, Greece); the decapod Penaeus hathor in Aegean waters; the decapod Penaeus aztecus and the nudibranch Melibe viridis in the Dodecanese islands; the finding of Pinctada imbricata radiata in the Mar Grande of Taranto (Ionian Sea, Italy) and the Maliakos Gulf (Greece).

5. Favna kačjih pastirjev (Odonata) okolice Hotunj pri Ponikvi (vzhodna Slovenija)Matjaž Bedjanič, 2022, izvirni znanstveni članek Povzetek: Za raziskovano območje podajam seznam 35 vrst kačjih pastirjev, opazovanih med majem in septembrom 2022, s pripadajočimi favnističnimi podatki. Na nacionalni rdeči seznam je uvrščenih šest vrst, medtem ko sta koščični škratec Coenagrion ornatum in veliki studenčar Cordulegaster heros zavarovana in uvrščena na dodatke Direktive o habitatih EU. Tudi najdbe prodnega paškratca Erythromma lindenii, deviškega pastirja Aeshna isoceles in črnega ploščca Libellula fulva so zanimive iz favnističnega vidika in jih predstavljam v širšem kontekstu njihove razširjenosti v Sloveniji. Na izbranih popisnih transektih vzdolž melioracijskih jarkov na ožjem raziskovanem območju severno od Hotunj sem zabeležil 32 vrst. Prikazana je dinamika števila vrst po posameznih popisih med sezono in pripadajoča dinamika naraščanja kumulativnega števila zabeleženih vrst. Za razmeroma majhno območje v okolici Hotunj je doslej skupno znanih 37 vrst kačjih pastirjev. Na širšem območju med Ponikvo in Dramljami so potrebne dodatne favnistične raziskave, saj je poznavanje biodiverzitete in naravovarstvenega pomena območja še zelo pomanjkljivo.

6. Biodiverziteta in varstvo slovenskega morja na pragu 21. stoletja : zbornik referatov1999, druge monografije in druga zaključena dela Povzetek: V preteklem letu so potekale tudi številne dejavnosti, kot so delavnice, posveti, kongresi doma in v tujini, predstavitve znanstvenih in poljudnih publikacij z morsko tematiko, prispevki v sredstvih javnega obveščanja, razstave, ples pomorščakov, tekmovanje jadralcev na deski za državni pokaf. Dobro obiskana je bila tudi tematska knjižna razstava "Morje, oceani in knjige" v knjižnici Piran. Ker ljudje lahko varujemo samo tisto, kar poznamo, je izobraževanju posvečena velika pozornost. Za izobraževalne namene smo v pretekiem letu pripravili, v sodelovanju z Regionalnim RTV centrom Koper-Capodistria, izobraževalni film, ki vključuje kratke dokumentarne oddaje, seminar za učitelje in profesorje, mladinske raziskovalne naloge z morsko tematiko. V mesecu juniju je v Fiesi potekal raziskovalni tabor Dnevi ustvarjalnih otrok (DUO), namenjen nadarjenim osmošolcem iz Slovenije, in mednarodni tabor za srednješolce. Ta je namenjen mednarodnemu sodelovanju mladih in je prek Urada za mladino vključen v program EURO PLATFORMA 98. Oba tabora je organiziralo Obalno društvo pedagoških delavcev v sodelovanju s podjetjem za kulturo in izobraževanje Forum Piranense. Na OŠ Ciril Kosmač je v oktobru 1998 potekaj 5. mednarodni izobraževalno - raziskovalni tabor. Organizirali so vrsto delavnic, med drugim tudi delavnico o problematiki onesnaženja obalnega morja. Omeniti moramo tudi prispevek najmlajših "Morje skozi oči Ankarana"- prispevek učencev 4. razreda OŠ Ankaran. Nacionalni program Slovenije je bil predstavljen organizaciji The Oceanography Society (TOS) in Intergovernmental Oceanographic Commission (IOC) v Parizu, ki bo gradivo vključila v načrtovano razstavo na sedežu UNESCa v Parizu. Na tej razstavi naj bi predvsem slikovno predstavili nacionalne dejavnosti v zvezi z Mednarodnim letom oceanov, nato pa naj bi bila razstava predvidoma prenesena v palačo Združenih narodov v New Yorku. Preteklo leto je v številnih državah sveta in tudi v Sloveniji potekalo podpisovanje Listine o oceanih. Listina je nepravni dokument, vendar poziv vsakemu posamezniku, da podpiše, da se bo pri igri, svojem delu in odločitvah, ki jih sprejema pri vsakdanjem ravnanju z morji, oceani in vodami, ki se vanje izlivajo, zavedal: - da je zdravje oceanov ter umno in previdno izkoriščanje njihovih bogatih ribjih lovišč in drugih naravnih virov osnovno načelo, ki ga mora sprejeti vsak posameznik, kot tudi sprejeti in spoštovati vlade vseh držav v prid dolgoročnih koristi in obstoja narodov sveta; - da mora biti spoznavanje in razumevanje morskega okolja in njegovih živih bitij osnova smotrnega gospodarjenja z oceani in morji, kot tudi odločanja o njihovem varovanju ter izkoriščanju virov. Listino o oceanih so predlagali na Svetovni konferenci o morjih septembra 1997 v St. John'su na Novi Fundlandiji v Kanadi. Državniško Listino o oceanih je podpisal predsednik vlade dr. J. Drnovšek ob svojem obisku slovenske uradne delegacije svetovne razstave EXPO '98 v Lizboni v paviljonu Združenih narodov. Ob otvoritvi razstave "Barve zaliva" v galeriji insula je Minister za okolje in prostor dr. P. Gantar podpisal Listino o oceanih. Podpisovanje Moje listine o oceanih pa je potekalo ob različnih priložnostih (prireditvah, razstavah, predavanjih, predstavitvah ...) in prek domače strani interneta.
