Biodiversity post-2020: Closing the gap between global targets and national-level implementation

National and local governments need to step up efforts to effectively implement the post-2020 global biodiversity framework of the Convention on Biological Diversity to halt and reverse worsening biodiversity trends. Drawing on recent advances in interdisciplinary biodiversity science, we propose a framework for improved implementation by national and subnational governments. First, the identification of actions and the promotion of ownership across stakeholders need to recognize the multiple values of biodiversity and account for remote responsibility. Second, cross-sectorial implementation and mainstreaming should adopt scalable and multifunctional ecosystem restoration approaches and target positive futures for nature and people. Third, assessment of progress and adaptive management can be informed by novel biodiversity monitoring and modeling approaches handling the multidimensionality of biodiversity change

Revision of the genus Squalius in Western and Central Anatolia, with description of four new species (Teleostei: Cyprinidae)

Chubs of the genus Swains in western and Central Anatolia are reviewed. Ten species are recognized. squalius anatolicus (Lake Beysehir basin, western Lake Tuz basin and Manavgat River), S. cephaloides (northern Armutlu Peninsula), S. cii (southern Marmara Sea basin), S. fellowesii (Madra River south to Esen River), S. kosswigi (Tahtali River), and S. pursakensis (Sakarya River) are valid species and are redescribed. Four new species are described: S. aristotelis from the Tuzla drainage, S. carinus from Lake Isikh basin, S. cappadocicus from Melendiz River in Lake Tuz basin and S. recurvirostris from Lakes Eber, Aksehir and Ilgin basins. An identification key is provided for the species recognized in Western and Central Anatolia

Oxynoemacheilus amanos, a new nemacheilid loach from the Orontes River drainage (Teleostei: Nemacheilidae)

Oxynoemacheilus amanos, new species, is described from Incesu spring in the upper Hupnik drainage, a northern tributary of the lower Orontes in Turkey. It is distinguished from the other Oxynoemacheilus species in the Eastern Mediterranean Sea basin by possession of an incomplete lateral line with 23-45 pores, terminating between the vertical through the dorsal fin origin and the anus, 10-13 pores in the infraorbital canal, a deeply emarginate caudal fin, no suborbital groove in the male, and a series of irregularly shaped and set dark-brown bars on the flank, not connected to saddles on the back

Barbus anatolicus, a new barbel from the Kizilirmak and Yesilirmak River drainages in northern Anatolia (Teleostei: Cyprinidae)

WOS: 000442494500005PubMed: 30314066Barbus anatolicus, new species, is described from the Kizilirmak and Yesilirmak River drainages in the southern Black Sea basin. It is distinguished from other Barbus species in the Middle East by having 58-71 total lateral line scales, a moderately ossified last simple dorsal-fin ray, serrated along about 70-80% of its posterior margin, many small irregular shaped black or brown spots, smaller or as large as scales, often forming large, dark-brown blotches on the head, back and flank in adults and juveniles, and a concave posterior dorsal-fin margin. in addition, DNA barcode data reject the hypothesis that it belongs to one of the other species of the B. barbus species group. Barbus bergi from Bulgaria and adjacent Turkey is treated as synonym of B. tauricus. Barbus tauricus was previously believed to be restricted to the Crimean Peninsula but is found to be widespread in the Black Sea basin.Leibniz Association Joint Initiative for Research and Innovation (SAW)We are grateful to Mufit Ozulug (Istanbul) and Esra Baycelebi (Rize) for help during fieldwork.

Validation of Alburnus timarensis from the Lake Van basin, eastern Anatolia (Teleostei: Cyprinidae)

The Lake Van basin located in eastern Anatolia is inhabited by two species of Alburnus: Alburnus tarichi is a migratory species foraging in the lake and spawning in all tributaries, while A. timarensis is resident in streams and is known only from one tributary of the lake, the Karasu. It could be shown that A. timarensis is a valid species, which is rediagnosed here. Both species are syntopic during the spawning season, but are well distinguished by size, gill raker and lateral line scale counts

Barbus anatolicus, a new barbel from the Kizilirmak and Yesilirmak River drainages in northern Anatolia (Teleostei: Cyprinidae)

Oxynoemacheilus isauricus, a new nemacheilid loach from Central Anatolia (Teleostei: Nemacheilidae)

Oxynoemacheilus isauricus, new species, from the Lakes Beysehir and Sugla basins in Central Anatolia is distinguished from all other species of the O. angorae group by having a very slender caudal peduncle (its depth 2.2-2.6 times in its length). The new species is further distinguished by having a short head (head length 21-24% SL), and a midlateral series of irregularly shaped blotches on the flank. Oxynoemacheilus isauricus is also distinguished by a minimum K2P sequence divergence of 7.5% and 8.0% in the mtDNA-COI barcode region from O. eregliensis and O. atili, its closest relatives

Garra orontesi, a new species from the Orontes River drainage (Teleostei: Cyprinidae)

Garra orontesi, new species, is described from the Orontes River drainage in the eastern Mediterranean Sea basin in Turkey and Syria. It is distinguished from its congeners in the Mediterranean Sea basin and adjacent Mesopotamia by possessing 17?21 gill rakers on the lower part of the first gill arch, the pelvic-fin origin usually below the second branched dorsal-fin ray, 81/2 branched dorsal-fin rays, usually 2?3 scales between the tip of the pectoral and pelvic-fin origins, and no tubercles behind the upper posterior eye margin. It is also distinguished by a minimum K2P distance of 2.7% in its COI barcode region against G. rufa, and 3.9% against the geographically adjacent G. turcica

Pseudophoxinus cilicicus, a new spring minnow from southern Anatolia (Teleostei: Leuciscidae)

Pseudophoxinus cilicicus, new species, is described from the Arsuz, Ccyhan and Seyhan river drainages in the Gulf of Iskenderun. It is distinguished from other members of the Pseudophoxinus zeregi species group by having a complete lateral line with 38-45 + 2-3 scales, the lower lip usually slightly projecting beyond the tip of the upper lip, a prominent black stripe along the flank, and no black pigments below the lateral line. Pseudophoxinus cilicicus is distinguished from P. zekayi by a minimum K2P distance of 3.8% based on the mitochondria! DNA barcode region. Pseudophoxinus atropatenus and P. sojuchbulagi are returned to the genus Rutilus

Revision of the genus Seminemacheilus, with the description of three new species (Teleostei: Nemacheitidae)

YOGURTCUOGLU, Baran/0000-0001-8144-6191WOS: 000548108000005PubMed: 33056045The nemacheilid genus Seminemacheilus is revised. Six species are recognised, three of them described herein as new. All species arc endemic to Central Anatolia. Seminemacheilus lendlii from the Sakarya River drainage and the cndorheic Lake Aksehir and Eber basins, S. ispartensis from Lake Egirdir basin and S. ahmeti from Sultan Sazligi are valid species. Although Seminemacheilus lendlii and S. ispartensis have almost identical COI sequences, they are distinguished by the shape of the caudal peduncle and the presence of scales on the caudal peduncle in S. ispartensis (vs. absent in S. lendlii). Seminemacheilus attalicus, new species, from Kirkgoz drainage, is distinguished by having a slightly emarginated caudal fin, a central pore in the supratemporal canal and a marbled flank pattern. Seminemacheilus elcmekciae, new species, from Lake Tuz basin is distinguished by having a roundish caudal fin, a short post-dorsal length and large brown blotches fused into stripes on the flank. Seminemacheilus tubae, new species, from Lake Beyehir basin, is distinguished by having a truncate caudal fm and 2-5 (6) supraorbital head pores. Seminemacheilus dursunavsari from the GOksu River drainage is not a valid name and this population is identified as S. tubae
