O HHD – HYLA Hrvatsko herpetološko društvo – Hyla osnovano je 1997. godine pod imenom "Društvo za zaštitu i proučavanje vodozemaca i gmazova Hrvatske-Hyla". Osnovano je od strane biologa i zaljubljenika u vodozemce i gmazove zbog potrebe zaštite ovih životinja koje su često i bezrazložno proganjane i ubijane. Također se pojavila potreba za zaštitom ekosustava i mnogih staništa na kojima obitavaju ove, ali i ostale skupine životinja. Društvo je 2004. preimenovano u današnji naziv te sa razvila unutrašnja infrastruktura u vidu web stranice (www.hyla.hr) i mailing liste koje održavaju povezanost članova i mreže regionalnih i lokalnih udruga i organizacija partnera. Društvo je registrirano kao strukovna organizacija te je većina članova biološke struke. Međutim, otvoreni smo za sve koje zanima zaštita i proučavanje hrvatske herpetofaune (vodozemaca i gmazova) i staništa. HHD-Hyla je punopravna članica IUCN (International Union for Conservation of Nature), najstarije i najveće međunarodne mreže za zaštitu prirode koja pod svojim okriljem okuplja više od 1000 članica - nevladinih i državnih organizacija - u više od 160 zemalja širom svijeta. HHD-Hyla je od 2012. članica udruženja udruga Hrvatski institut za biološku raznolikost HIB zajedno sa svojim partnerima Udrugom za biološka istraživanja – BIOM, Hrvatskim društvom za biološka istraživanja HDBI i Hrvatskim mirmekološkim društvom HMD. Projekti i aktivnosti usmjereni su na istraživanja te zaštitu vrsta i staništa, edukaciju lokalnog stanovništva i šire javnosti (u sklopu projekata ali i zasebna predavanja i radionice), edukaciju studenata te izdavanje publikacija i ostalog edukativnog materijala. Društvo je aktivno na nacionalnoj razini te provodimo projekte u raznim dijelovima Hrvatske uz suradnju s državnim i lokalnim institucijama, udrugama, stručnjacima u zemlji i inozemstvu, školama te lokalnim stanovništvom.

About HHD - HYLA Croatian Herpetological Society - Hyla was founded in 1997 under the name "Society for the protection and study of amphibians and reptiles in Croatia-Hyla". It was established by the biologists and nature enthusiasts because of the need to protect amphibians and reptiles which are often unduly persecuted and killed. The need for protection of ecosystems and many habitats, on which this and other groups of animals reside, also occured. In 2004 Society was renamed to its present name and we developed an infrastructure, web site (www.hyla.hr) and mailing list, through which we maintain cohesion between members and a network of regional and local NGOs and partner organizations. Society is registered as a professional organization, and the majority of our members are biologists. However, we are open to all people interested in research and conservation of Croatian herpetofauna (amphibians and reptiles) and habitats. HHD-Hyla is a full member of the IUCN (International Union for Conservation of Nature), the oldest and largest international network for the protection of nature, with more than 1000 members - government and non-government organizations - in over 160 countries around the world. HHD-Hyla is since 2012 a full member and the founding party of the Croatian Instiute for Biodiversity CIB together with its partners Association for Biological Research – BIOM, Croatian Biodiversity Research Society HDBI and Croatian Mirmecological Society HMD. Projects and activities are focused on research and protection of species and habitats, education of the local inhabitants and public (during the projects, as well as separate lectures and workshops), training of students and publishing of the various scientific, professional and educational materials. Society is active at the national level and implements projects in different parts of the Croatia in cooperation with national and local institutions, NGOs, national and international experts and scientists, schools and local inhabitants.

Corresponding author: BORIS LAUŠ, Croatian Institute for Biodiversity and Croatian Herpetological Society HYLA, Prva Breznička 5a, 10000 Zagreb, boris.laus.pmf@gmail.com Abstract Over the four year period (2007–2010), the authors conducted a field study aimed at drawing up an inventory of batrachofauna and herpetofauna of the Zrmanja river catchment area. Eight species of amphibians and twenty one species of reptiles were detected; through the available literature overview two more reptilian and one amphibian species were added to the list. Therefore, we proved the presence of thirty two species in total. High diversity of amphibians and reptiles indicates great significance of this area and imposes the need to ensure survival of these species through long-term populations monitoring and conservation measures. Key words: Amphibians, Reptiles, Zrmanja, Conservation

Sažetak Kroz period od četiri godine (2007–2010), autori su proveli terenska istraživanja u cilju inventariziranja batrahofaune i herpetofaune slivnog područja rijeke Zrmanje. Zabilježeno je osam vrsta vodozemaca i dvadeset i jedna vrsta gmazova, dok su pregledom dostupne literature za ovo područje zabilježene još dvije vrste gmazova i jedna vrsta vodozemaca, čime je dokazana prisutnost ukupno trideset i dvije vrste. Velika raznolikost vodozemaca i gmazova upućuje na izniman značaj ovog područja i nameće potrebu za osiguranjem opstanka ovih vrsta kroz dugoročno praćenje stanja njihovih populacija i provođenje neophodnih mjera zaštite. Ključne riječi: vodozemci, gmazovi, Zrmanja, zaštita

INTRODUCTION Zrmanja is a 69 kilometres long river in southern

Croatia. Its spring is located at 395 m a.s.l. beneath the

area and their endangerment status is discussed in

Mount Poštak in the southern part of Lika, and flows into

canyon, passes through the city of Obrovac and finally flows into the Novigrad sea. The entire area we surveyed during the present research belongs to the region of the southern Hrvatsko Primorje (or North Dalmatia), i.e. Zadar region, except for the mere area of the Zrmanja spring beneath the Mount Poštak, which belongs to the Lika region (Crkvenčić et al. 1974). Along its course towards the Novigrad sea, Zrmanja passes through larger area of Bukovica and Ravni Kotari. Rock composition of the entire area of Ravni Kotari belongs to the Upper Cretaceous and Tertiary calcareous rocks, that extend in Dinaric direction (northwest–southeast), while in the opposite direction (southwest–northeast) we have rotation of calcareous convex folds (anticlines) and downward folds (synclines). The area of Bukovice is a higher and more open calcareous plateau which is surmounted by calcareous Velebit mountain range. Prevailing substrates are

deposits),

calcareous breccias and conglomerates with intercalations of softer and more fertile marlstone and bauxite deposits (Crkvenčić et al. 1974). The result of such relief is a broad spectrum of microclimatic conditions. Climatic differentiation in the Zadar region is the most obvious in diversity of plant communities: true Mediterranean vegetation (evergreen macchia) is present along the Adriatic sea coast and in the islands, Sub-Mediterranean plants (oak and hornbeam) dominate in Ravni Kotari, and in Bukovica these are replaced by more mountainous plant communities

Towards the coastline, this type of climate transforms into the Csa class, Mediterranean or dry subtropical climate, and from the Zrmanja spring towards the continent it changes into the Cfb class, marine west coast climate (Šegota & Filipčić, 2003).

Abstract In this paper we present newly collected data and historical overview of the herpetofauna of Neretva River Valley. During two consecutive years (2011, 2012) we collected new data about the presence of reptiles and amphibians in the area, on 25 sampling sites, of which 21 in Croatia and 4 in Bosnia and Herzegovina. During our survey we recorded the presence of 21 species of which 18 are listed in the IUCN Red list. The literature records added another 13 species, so the total number for amphibians and reptiles in the area is 34 species, 11 amphibian and 23 reptiles. With such a high diversity, the area of Neretva River is one of the hotspots of the amphibian and reptile diversity in Croatia. Lower Neretva Valley is now days under a strong anthropogenic influence, and most of the area is used for plantations and intensive agriculture. It is of a critical importance to conserve and protect the remaining natural habitat in the future.

Key words: amphibians, reptiles, diversity, conservation

Sažetak U ovom radu predstavljamo novo prikupljene podatke, kao i povijesni pregled herpetofaune doline rijeke Neretve. Tijekom 2011. i 2012. godine prikupili smo podatke o prisutnosti vodozemaca i gmazova na 25 lokaliteta, od kojih se 21 nalazio u Hrvatskoj a 4 u Bosni i Hercegovini. Tijekom našeg istraživanja utvrdili smo prisutnost 21 vrste, od kojih je 18 navedeno na IUCN-ovom Crvenom Popisu. Literaturnim nalazima utvrdili smo prisutnost još 13 vrsta, tako da je poznati broj vrsta na području Neretve 34, od čega 11 vrsta vodozemaca i 23 vrste gmazova. Sa ovolikim brojem vrsta, područje rijeke Neretve može se smatrati vrućom točkom bioraznolikosti vodozemaca i gmazova u Hrvatskoj. Donji tok rijeke Neretve je danas pod snažnim antropogenim utjecajem, i veći dio se upotrebljava za plantaže i intenzivnu poljoprivredu. U budućnosti će biti od ključne važnosti očuvati preostala prirodna staništa toga područja.

Ključne riječi: vodozemci, gmazovi, raznolikost, zaštita

reptiles for regions or for the whole country exists, so it can be stated that the herpetofauna of Croatia is not sufficiently known. This confirms the large number of faunistic papers published during the last decades (e.g. Tóth et al. 2006; Koren et al., 2011; Jelić et al. 2012; Jelić & Karaica, 2012), which greatly contributed to the knowledge of the herpetofauna of some areas. However, many areas still lack basic data about herpetofauna or the data is more than 100 years old and unusable for conservation purposes. No systematic surveys of amphibians and reptiles of Neretva River were ever done. Only several extensive papers exist (e.g. Werner, 1897; Bolkay, 1925; 1928; Bressi, 1999) while most other papers only contain one or few records (e.g. Radovanović, 1941; Werner, 1905). The aim of this study is to give a first overview of the herpetofauna of lower Neretva Valley from the newly

RESULTS AND DISCUSSION In the surveyed literature we found the records of 11 amphibian and 23 reptile species for the area of lower Neretva Valley. The list of all new, as well as literature records is presented here. During this survey we managed to find, observe or catch 139 amphibians and

reptiles. Altogether 21 species were recognized, from which 4 amphibians and 17 reptiles (Tab. 3). This represents 36% of the herpetofauna of Croatia (JanevHutinec et al., 2006). All recorded species were recorded in Croatia, but only 5 species were recorded in Bosnia and Herzegovina, due to the small number of field days (4 days) that we spend there.

of Neretva Valley (Bolkay, 1928; Dragobratović, 2007) (Fig 3). The area of Neretva is probably not an ideal habitat for this species, which needs small, clean streams for their development. No new records of this species were found, but the best habitat for this species should be the area from Baćinska lakes and the surroundings of Modro Oko. These areas are still rich in different habitat types, including forests. Such habitats have almost completely disappeared from the surroundings of river Neretva itself. Figure 4.

Pelophylax lessonae (Camerano, 1882) Only Karaman (1921) mentions this species for Prud, Neretva (Fig. 10). Hoverer, this species inhabits only the northern parts of Croatia and Bosnia & Herzegovina, so its presence here is highly doubtful, and the record is probably result of misidentification with P. ridibundus.

Rana dalmatina Fitzinger in Bonaparte, 1838 Only two records of R. dalmatina are known from the Neretva river valley (Bolkay, 1928; Dragobratović, 2007) (Fig. 12). This species predominately inhabits forests and wet grasslands, which are rare in the area. We recorded R. dalmatina in two new localities, Baćinska lakes and Modro oko. Only one individual per locality was recorded. This species can be regarded as rare member of Neretva river fauna.

Emys orbicularis (Linnaeus, 1758) Bolkay (1924) was the first who mentions the presence of this species in Metković. After that, it is mentioned in Neretva river valley (Bolkay, 1928; Fritz, 1992), the area from the river delta toward village Drežnice (Bolkay, 1928) (Fig. 16). This freshwater species is probably present in all water channels in the area of Neretva river valley. Our only record originates from a water channel, near Blace. There we found, among dead and discarded fishes, an almost dead male E. orbicularis. The fishes and this terrapins were probably discarded as a side catch of hunting pot. After few hours this individual regained conscience and was released in the same locality. Hunting pots are commonly used by local inhabitants to

Literature records include Gabela (Bolkay, 1928), Neretva river valley (Bolkay, 1928) and Opuzen (Bressi, 1999). We recorded it on two localities Blace and Kamp Rio (Fig. 17).

Podarcis melisellensis (Braun, 1877) This is the commonest lizard species in the area, historically recorded on many localities. The first literature record originates from Metković (Werner, 1905). Bolkay (1924) reports it from Karaotok, Hutovo Blato, and later (Bolkay, 1928) from Mogorjelo, near Čapljina, Čapljina, Neretva river valley Čapljina and the area from the river delta toward village Drežnice. Radovanović (1941) also mentions it for Čapljina, and Figure 19. Records of L. agilis in the area of Neretva River. White dots represent literature records. Slika 19.

Bressi (1999) from the area of Neretva. We recorded it at Markote, Dubrovica, Kamp Rio near Opuzen, Blace, Vidonje, Lovorje, Trna, Baćinska lakes and Sestrun (Fig. 21).

Lacerta trilineata Bedriaga, 1886 From the three species of green lizards, L. trilineata is one of the largest lizard species present in the area. There are 6 literature records of this species: Hum by Metković (Bolkay, 1924), Neretva Valley (Bolkay, 1928; Bressi, 1999), area from the river delta toward village Drežnice (Bolkay, 1928) and Opuzen (Bressi, 1999) (Fig. 20). This species is very common in the area and present almost everywhere. We recorded it on following localities: Blace, Vidonje by Metković, Modro oko, Lovorje, Podgradina, Trn, Baćinska lakes and Sestrun by Rogotin.

Podarcis muralis (Laurenti, 1768) The wall lizard is widespread and moderately common in most parts of Croatia. The literature records include Metković (Werner, 1897), Dračevo by Metković (Werner, 1898; 1899), Čapljina (Boulenger, 1905) and Neretva river valley (Werner, 1905) (Fig. 22). We recorded this species at Trn, near Opuzen. As the last

1928), Neretva river valley (Bolkay, 1928; Bressi, 1999) and Neretva delta (Werner, 1905). We recorded it on many localities, including Blace, Čitluk, Kamp Rio near Opuzen, Komin, Krvavac, Vidonje, Vid, Modro oko, Lovorje, Trn, Baćinska lakes, Sestrun, Vrijaci, Tuštevac and Žitomislići (Fig. 24). What was surprising to us was the large number (>20) of juvenile specimens that we recorded in the area. Usually the adult’s are very common and juveniles and sub adults very rare. It is Figure 22.

common in the whole area.

Anguis fragilis Linnaeus, 1758 While very common in northern Croatia, this species is rare in Dalmatia. In the area of Neretva it was recorded from Neretva river valley (Bolkay, 1928; Bressi, 1999), Metković (Džukić, 1972) and Opuzen (Bressi, 1999) (Fig. 23). We spent a lot of time in the field searching for this species, but we did not confirm its presence in the area.

Malpolon insignitus (Geoffroy Saint-Hilaire, 1827) The Montpellier Snake was first time mentioned by Bolkay (1924) for the area of Metković. Later, Bolkay (1928) mentions the records from Neretva river valley, from the delta toward Drežnice. This species is very common in the area, but it is only seldom spotted. The easiest way to record its presence is by surveying the roads for carcasses. We recorded it at Kamp Rio by

Natrix tessellata (Laurenti, 1768) As well as N. natrix this area is quite suitable for N. tessellata. This species was recorded in Neretva river valley (Kolombatović, 1882; Werner, 1897; Bolkay, 1928), in the area from Drežnice village toward river delta (Bolkay, 1928) and Baćinska lakes (Janev-Hutinec &Mebert, 2011) (Fig. 27). During our survey we observed this species on many localities including Vidonje, Kamp Rio by Opuzen, Blace, Modro oko, Figure 25. Records of M. insignitus in the area of Neretva River. White dots represent literature records, black dots represent new records. Slika 25. Nalazi vrste M. insignitus na području rijeke Neretve.

Baćinska lakes, Trn and Vid. This is the commonest snake in the area, and many specimens (>30) were seen dead on road.

Natrix natrix (Linnaeus, 1758) With many water habitats, including rivers, streams and channels, the area of Neretva represents an ideal habitat for water snakes. Literature records include Metković (Bolkay, 1924), Neretva river valley (Bolkay, 1928), in the area from Drežnice village toward river delta (Bolkay, 1928) and Baćinska lakes (Janev-Hutinec & Mebert, 2011). We recorded this species at Kamp Rio by Opuzen, Vidonje, Vid, Modro oko, Blace, Rogotin and Sestrun (Fig. 26).

Coronella austriaca Laurenti, 1768 This species is very secretive and sometimes it is one of last species recorded in the area (Jelić, 2010; Hill, 2008). Few records exist for the area of Neretva: Dračevo by Metković (Werner, 1898; 1899), Neretva valley (Bolkay, 1928) and in the area from Drežnice village toward river delta (Bolkay, 1928) (Fig. 28). We did not confirm the

occurrence of this rare species in the area. Elaphe quatuorlineata (Bonnaterre, 1790) This is probably one of the largest, but also timid snakes of Croatia. It inhabits the Mediterranean part of the country, including the Neretva river valley. There are several literature records of this species for the area: Neretva river valley (Werner, 1897; Bolkay, 1928),

Platyceps najadum (Eichwald, 1831) This species is very rarely encountered due to its slender body and great speed. Literature records include Neretva river valley (Werner, 1897; Bolkay, 1928) and the area from Drežnice village toward river delta (Bolkay, 1928). We did not manage to find any live specimens, but did find one run over male at Tuštevac village (Fig. 31). This species is probably present only on the karstic habitats in the area.

This is the only species of snakes that is predominately active in the evening and during the night. Literature records include Neretva river valley (Bolkay, 1928) and the area from Drežnice village toward river delta (Bolkay, 1928) (Fig. 32). The simplest way to record this species is to drive around by car in the evenings and during the night. In this way we searched almost whole areas, especially the roads from Ploče toward Rogotin and Opuzen, but did not manage to confirm its presence in the area.

DISCUSSION The data collected during our field trips can be divided in two periods: spring time (April-May) and summer period (July-August). This is very important because the activity especially of reptiles vary greatly in the Mediterranean regions in different seasons. While in the spring, the temperatures are not so high, and the animals are more active, in the summer times the temperatures are very high, and most of the species are not active at all Figure 35.

during the day. This can be clearly seen when a comparison between these two periods is done, bearing in mind that the hunting effort was more or less the same over both periods. In the spring time, we managed to record 20 species, while in the summer period only 11 species were recorded. The number of recorded specimens was also very different in both periods (Fig. 36).

CONSERVATION NOTES While in the past lower Neretva Valley was a place full of biodiversity, nowadays it is under a strong anthropogenic influence. The delta itself, with the surface area of 120 km2, is a wetland area protected by the Ramsar Convention. The melioration of this area began long in the past, but the most intensive process which modelled the today’s delta was done in the period between the years 1950-1980. Nowadays, most of the area is covered in different kinds of plantations,

Also, a high observed number of road kills, especially snakes (M. insignitus, N. tessellata) are due to have a signification impact to their populations. Such conditions are far from favourable for both amphibians and reptiles. The situation is much better in the surrounding karstic

Colour abnormalities in Coronella austriaca (Laurenti, 1768) in Croatia Neuobičajena obojenja kod Coronella austriaca (Laurenti, 1768) u Hrvatskoj BORIS LAUŠ1, IVONA BURIĆ1 1

Croatian Herpetological Society HYLA, Prva Breznička 5a, 10000 Zagreb, Croatia, boris.laus.pmf@gmail.com; ivona.burich@gmail.com

Production of colour in reptiles depends on cells called chromatophores. There are four kinds of chromatophores in the skin: melanophores for black, erythrophores for red, xanthophores for yellow and iridophores, which do not contain true pigment, and are in fact reflectve cells that produce white when it reflects incident light. They also account for other colours such as blue and khaki (Bechtel, 1978). Abnormalities may occur during chromatogenesis, resulting in the absence of some pigments. Such abnormalities are well known in European Viperinae (Krecsak, 2008), but are also reported for some species of European Colubridae. The Smooth snake (Coronella austriaca) is one of those species, with just a few observed cases of colour abnormalities: a case of melanism (Pernetta & Reading, 2009), partial albinism (Lenders, 1989), lutinism or leucism (Niebergall, 2008) and albinism (Happ, 1994). Here we present two recorded cases of genetic discolouration in Smooth snakes from Croatia: presumably anerythristic (Fig. 1a) and presumably hypomelanistic (Fig. 1b). Hypomelanism stands for the reduction of dark pigment - melanin, and anerythrism signifies absence of red pigment. The hypomelanistic Smooth snake was observed in July 2012, at Tijarica Donja, Dalmatia (X: 5652863, Y: 4830212), and the anerythristic Smooth snake in April 2009, at Stubičke Toplice, Hrvatsko zagorje. For comparison, we present two specimens of common colouration (Fig. 1c, from April 2009, Grmošćica (Zagreb), and 1d, from August 2010, Mt Poštak).

Normal diet of this lizard consists of different invertebrates and occasionally vertebrates (Arnold & Ovenden, 2002). In this short report we present cannibalistic behaviour observed in P. apodus. During field work in vicinity of Split, Croatia, on May 22th, 2011 we found adult female of P. apodus laying in the meadow, partially hidden between 30 cm tall grass, 2 m from nearest bush, with conspecific juvenile protruding from its mouth (43°32’N; 16°31’ E). It was 18:45 PM, clouded, with no wind. We measured animals and habitat characteristics before realising female to nearby bush (Table 1).

PRAVILA ZA ISPUNJAVANJE POPISNOG LISTA -

Popisne listove ispunjavati po povratku s terena - prepisati podatke iz terenske bilježnice.

-

Popisne listove treba ispunjavati tako da jedan list predstavlja samo jedan lokalitet i samo jedan dan opažanja tog lokaliteta. Također, ako se obilazi jedan veći lokalitet s više različitih staništa poželjno je upotrijebiti više popisnih listova.

-

OBAVEZNO priložiti fotografiju vrste izbliza kako bi mogli potvrditi točnost determinacije. Fotografije pošaljite kao dodatni attachment u e-mail poruci.

Popisni listovi se ispunjavaju na slijedeći način: ŽUPANIJA: Upisati županiju u kojoj se određeni lokalitet nalazi. NAJBLIŽE NASELJE: Upisati najbliže naseljeno mjesto. OPIS LOKALITETA: Upisati najbliži toponim (npr. planinski vrh, prijevoj, naselje…) te udaljenost i smjer od toponima. Upisuju se hrvatske kratice za strane svijeta. Također što detaljnije opisati lokalitet i kako doći do njega. KOORDINATE I NADMORSKA VISINA: Očitati ili pomoću GPS uređaja ili s karte te naznačiti na koji način su dobiveni podaci. Ako su koordinate očitane s karte naznačiti mjerilo karte. OPIS STANIŠTA: Pobliže opisati tip staništa na kojem su nađene jedinke (morfologija staništa, vegetacija, tip podloge, mikrostanište...). VRIJEME I TEMPERATURA: Zaokružiti vremenske prilike; ako imate termometar sa sobom izmjeriti temp. zraka (mjerena u hladu na oko 1 m od tla), odnosno vode (mjerena u hladu, oko 10 cm ispod površine) ovisno o staništu pojedine vrste. FOTO: Priložiti fotografiju nalaza. Upisati naziv priloženog dokumenta. VRSTA: Upisati ime vrste te broj jedinki u odgovarajući stupac, upisati i spol ako je poznat (JUV – do 1 godine starosti; SAD – subadultne jedinke, više od 1 godine starosti; AD – odrasle, spolno zrele jedinke; ako je poznat spol upisati M - mužjak i/ili F - ženka). Ako ste pronašli uginule jedinke normalno ih upišite i pod rubriku NAPOMENE navedite da su uginule. Na kraju lista nalazi se prostor za upisivanje podataka osobe koja je ispunila popisni list.
