The genera Nigella and Garidella are two members of the Nigelleae tribe. Among all the taxa of the tribe, black cumin (Nigella sativa L.) is one of the most important plants concerning economic and medicinal uses. In this study, volatiles were analyzed in detail to elucidate the phytochemical profiles and to understand the taxonomic patterns of sec...
Article
Despite global and local evidence of significant precipitation changes since the Little Ice Age (LIA), their impact upon lake hydrology and surrounding vegetation has yet to be investigated in NW Anatolia. Moreover, the LIA, as a trigger to the social/political recession of the Ottoman Empire in the 17th century is expected to have these impacts. T...

In this study, the high-resolution palynological data derived from two cores taken from Mogan Lake in the Gölbaşı Basin of the Ankara region in central Anatolia (Turkey) are presented. The results provide the palaeobotanical, palaeoclimatological and palaeoenvironmental records of the last ca. 3100 years for the region which is characterised by ric...

The genus Nigella L. s.l. (Ranunculaceae) is one of the most important plants in respect of economic and medicinal usage. Fatty acid compounds have been researched in detail for the taxa of Nigella s.l., naturally growing in Turkey. Among them, 19 Nigella taxa were researched in respect of 18 fatty acid compounds. These were acquired by the way of...

Oybak Dönmez E. 2008. Pollen morphology in Turkish Crataegus (Rosaceae). Bot. Helv. 118: 59 – 70. Pollen morphology of 20 Turkish Crataegus L. taxa (Rosaceae) was studied using light and scanning electron microscopy to assess whether pollen traits are of taxonomic value in this species group. The most frequent aperture type was tricolporate, but n...

Plant remains were recovered from an Urartian settlement, Yoncatepe, situated in the Van province of eastern Turkey and dating to the Iron Age period (first millennium B.C.E.). Large quantities of hulled barley (Hordeum vulgare L.) and of bread/macaroni wheat (free-threshing wheat) Triticum aestivum L./T. durum Desf.), both mixed with small quantit...

Pollen morphology of the Turkish Romulea Maratti taxa (Iridaceae) was examined using light and scanning electron microscopy. The taxa are similar in some aspects, such as pollen size and spinulate-microperforate exine sculpturing. Most taxa are monosulcate; however, in 2 taxa, R. bulbocodium (L.) Seb. & Mauri var. crocea (Boiss & Heldr.) Baker and...

The results of the archaeobotanical examination of 2 sites, namely Mezraa Höyük and Gre Virike, on the Euphrates in the Karkamiş (Carchemish) area, near Birecik (Şanhurfa) in south-east Turkey are given. The cultural levels that yielded carbonised plant remains date from the Early Bronze Age (3000-2000 BC), Middle Bronze Age (2000-1500 BC) and Medi...

Carbonised plant remains discovered in the Early Bronze Age (II) levels of Yenibademli Höyük on Gökçeada, one of offshore islands of west Anatolia, are presented. Archaeobotanical analysis of the plant remains dating from ca. 2900-2600 BC yielded a broad spectrum of crop plants comprising cereals and legumes, the latter of which appears to be of gr...

... Lentic habitat sediments reflect records of past physical, chemical and biological structure and habitat properties of lakes and their surrounding environments. Comparison of past fossil species with present-day diatom species gives sufficient information about environmental changes such as climate changes, eutrophication and pollution that the ecosystem has been exposed to from past to present (Dönmez et al., 2021;Ruwer et al., 2021;Shibabaw et al., 2021). Many paleolimnological records use diatoms due to their sensitivity to limnological characteristics and well-preserved silica cell walls (Avendaño et al., 2021;Levi et al., 2016;Maslennikova, 2020). ...
... Buckthorn is an old natural dye source, and the main dye component can be reported as quercetin, emodin, or kaempferol (Donmez et al. 2017;Karadag, Buyukakinci, and Torgan 2020;Poulin 2018). The bath of blank dyeing, which means it contains only natural dye sources in the dyeing process without the addition of fabric and any mordant, was centrifuged after the dyeing process. ...
... In archaeobotanical studies performed in Tilbaşar Höyük (Kavak et al., 2019), Titriş Höyük (Hald ,2010), and Yenibademli Höyük (Oybak Dönmez, 2005), Early Bronze Age layers show plant remains to belong to Triticum monococcum (einkorn wheat), Triticum dicoccum (emmer wheat), Hordeum vulgare (barley), Lens culinaris (lentil), and Vicia ervilia (bitter vetch). The agricultural products of these EBA settlements and Tatarlı Höyük are the same, and Triticum aestivum (bread wheat) was also not found there during this period (Table 3). ...
... Lake Sünnet, 15 km to the SE, comprises a continuous early Holocene record as terraces, but the late Holocene sediments are not easily accessible because of the water depths (Ocakoğlu et al., 2011bOcakoğlu et al., , 2013). Lake Çubuk, presented herein, is one of a series of early Holocene landslide-dammed lakes triggered presumably by earthquakes sourced from the nearby North Anatolian Fault Zone (NAFZ) (Figure 1b; Abdüsselamoğlu, 1959; Kır, 2010; Ocakoğlu et al., 2011a Ocakoğlu et al., , 2011b Tunoğlu et al., 2011). Sedimentation in these lakes has been very high because of the landslide damming, yielding a high-resolution lake record. ...
... The genus Romulea Maratti belongs to the subfamily Crocoideae (syn. Ixioideae), which includes over 800 species and about 30 genera and is the largest subfamily of Iridaceae (Iş ik and Dönmez, 2007;Kutbay et al., 2001;Özdemir et al., 2011). According to different authors (Béguinot, 1907(Béguinot, , 1909Čarni et al., 2014;Marais, 1980), the genus comprises about 95 species, most of which are found in southern Africa and the Arabian Peninsula (Manning and Goldblatt, 2001); about 15 species can be found in the Mediterranean basin (Peruzzi et al., 2011). ...
... Orobanche species are characterized by slight morphological diagnostic characters; hence, they are difficult to distinguish in terms of taxonomy (cf. Domina et al., 2011;Zare & Dönmez, 2013;Zare et al., 2014;Konarska & Chmielewski, 2019). Moreover, dried specimens lose colors and become brownish to blackish, making herbarium specimens difficult to identify (see e.g., Manen et al., 2004;Piwowarczyk et al., 2011Piwowarczyk et al., , 2014Piwowarczyk et al., , 2015. ...
... Currently, foxtail millet does not appear in Central Asia before 1500 BC. Moreover, it only appears cultivated in quantity in Anatolia at Ayanis and Tille Höyük in the Iron Age66,78 . Setaria is the only millet and the oldest dated in the Western Caucasus (Pichori, Abkazia), and it is well represented alongside Panicum, at slightly later sites (Namcheduri and Choloki) near Pichori, on the Black Sea coast. ...
... However, according to Erol et al. (2006), Karaismailoğlu (2015), Karaismailoğlu et al. (2018), Tekşen et al. (2021) and Sağıroğlu et al. (2022), seed features are important characters for species differentiation in the genus. In addition to macromorphological characters, previous studies examining seed and pollen micromorphology of Gladiolus taxa in Türkiye were also reviewed (Erol et al. 2006, Oybak Dönmez & Işık 2008, Tekşen et al. 2021, Sağıroğlu et al. 2022). ...
