Öğe AN ECOLOGICAL STUDY OF ENDEMIC PLANT POLYGONUM ISTANBULICUM KESKIN AND ITS ENVIRONS(Pakistan Botanical Soc, 2013) Altay, Volkan; Ozyigit, Ibrahim Ilker; Keskin, Mustafa; Demir, Goksel; Yalcin, Ibrahim ErtugrulIn this study, some ecological features of narrow endemic Polygonum istanbulicum Keskin, which was established as a new plant species in 2009, and its environs were examined. There are 41 known Polygonum taxa in Turkey and the genus is represented by 14 species in Istanbul. Plant and soil samples were collected from the place where the species merely lives in the world (Basibuyuk Forest, Maltepe District, Istanbul/Turkey). Plant and soil samples were collected by using standard methods and root, branch, leaf and soil mineral nutrients (Ca, Cu, K, Mg, Mn, N, P, Na, Zn), were measured. Additionally, soil texture, structure and other physical and chemical measurements such as pH, total protein and electrical conductivity (EC) were determined.Öğe An ecological study of endemic plant Polygonum istanbulicum Keskin and its environs(2013) Altay, Volkan; Ozyigit, Ibrahim Ilker; Keskin, Mustafa; Demir, Goksel; Yalcin, Ibrahim ErtugrulIn this study, some ecological features of narrow endemic Polygonum istanbulicum Keskin, which was established as a new plant species in 2009, and its environs were examined.

As we cannot find these endemic plants everywhere, they are not found in people’s daily consumption preferences. In this chapter, it is aimed to list potential endemic plants that may serve as promising future sources of food, spice, and herbal tea in Turkiye. In Turkiye’s traditional knowledge, a total of 103 endemic food plants, 23 endemic spice plants, and 59 endemic herbal teas have been found to be used. The most common endemic food plants used are cooked, followed by raw, suck the nectar, and eaten fresh. Some of the endemic plants, especially species belonging to the genera Allium, Cerasus, Digitalis, Gypsophila, Origanum, Ranunculus, Scorzonera, Sideritis, and Thymus, collected are also sold in the local neighborhood markets. In addition, in terms of contributing to the country’s economy, Allium tuncelianum and Origanum minutiflorum are important endemic plant species exported abroad. © 2024 by Apple Academic Press, Inc.Öğe Polygonum mersinicum (Polygonaceae), a new species from Turkey(Finnish Zoological Botanical Publishing Board, 2022) Keskin, Mustafa; Karahan, Faruk; Severoglu, ZekiPolygonum mersinicum M. Keskin sp. nova (Polygonaceae) is described from Turkey. It resembles especially P. karacae but differs from it by several morphological characters such as a short stem, glandular indumentum, shorter leaves, type of ochrea, shorter tepals, and longer nuts. Diagnostic features, a comprehensive description and images of P. mersinicum are provided.Öğe Some ecological characteristics and the flora of Gölcük District and its environs (Kocaeli-Turkey)(2011) Severo?lu, Zeki; Altay, Volkan; Özyi?it, Ibrahim Ilker; Keskin, Mustafa; Serin, Memduh; Yarci, Celal; Yaşar, ÜlkühanSome ecological characteristics and the flora of Gölcük District and its environs are represented in this study. All the greenery in the district during 2006 to 2009 vegetation seasons was explored. Plant samples were collected, dried, labeled, and determined according to the standard herbarium methods. At the end of the study, 461 species belonging to 295 genera and 85 families were identified. Seven of the identified taxa belonged to Pteridophyta while 454 belonged to Spermatopyta divisions. Eight taxa were Gymnospermae and 446 taxa were Angiospermae members (386 of them Dicots and 60 of them Monocots) in the Spermatophyta division. In addition, four taxa were endemics, so the endemism ratio was 0.87%. The most commonly found plant taxa were in Fabaceae family with 57 taxa (12.36%), and other families; Asteraceae 50 taxa (10.85%), Poaceae 33 taxa (7.16%), Rosaceae 22 taxa (4.77%) and Brassicaceae 21 taxa (4.56%). Species containing the highest number of genera were represented with Trifolium (14 taxa, 3.04%), Lathyrus (12 taxa, 2.60%), Vicia (nine taxa, 1.95%) and Quercus (eight taxa, 1.74%) respectively. Life forms were found in the following categories: hemicryptophytes (33.41%), therophytes (32.97%), phanerophytes (18.66%), geophytes (12.80%) and chamaephytes (2.16%). Phytogeographical origins of the taxa were as follows; 98 taxa (21.26%) were from Euro-Siberian elements (including Euxine), 57 taxa (12.36%) consisted of Mediterranean elements (including East Mediterranean), four taxa (0.87%) were of Irano-Turanian origin. Finally, 97 taxa (21.04%) were widespread and 9 taxa (1.95%) were cosmopolitan while phytogeographical origins of 302 taxa were unknown. © 2011 Academic Journals.Öğe Traditional Use of Plant Diversity for Nutritional Purposes: A Case Study from Istanbul (Turkiye)(Apple Academic Press, 2023) Keskin, Mustafa; Altay, Volkan; Öztürk, MünirMany of our traditionally consumed food plants are not generally available on our dining tables due to the established food preferences of humans. These include edible wild plants with an alternative potential to be used as human food. Therefore, this chapter presents data on the vascular flora of Istanbul with an aim to list the potential food plants that could serve as a promising food source in the future because of food shortages that may arise from climate change. A total of 2258 vascular plant taxa belonging to 127 families have been identified in the checklist prepared for the flora of Istanbul. In the checklist, we have found out that consumption possibilities that include leaf parts of 242 taxa, fruits of 70 taxa, underground parts of 57 taxa, floral parts of 35 taxa, seeds of 26 taxa, and aboveground parts of 21 taxa depict potential for use as edible food plants. In many parts of Turkiye, especially in Istanbul and nearby areas, these identified taxa may serve as important edible food plants for humans, offering an alternative food source. © 2024 by Apple Academic Press, Inc.Öğe Türkiye'de biyodizel üretiminde karşılaşılan sorunlar ve çözüm önerileri(Hatay Mustafa Kemal Üniversitesi, 2013) Keskin, Mustafa; Erdoğan, YasinEnerji, ülke ekonomileri için çok önemli yer tutmaktadır. Artan nüfusla birlikte her geçen gün enerji ihtiyacı artmaktadır. Geçmişte yaşanan petrol krizleri, savaşlar, petrol fiyatlarındaki dalgalanma, ulusal bağımsızlık, çevresel faktörler, bilinen üretilebilir fosil yakıt rezervlerinin yakın zamanda tükeneceği düşünüldüğünde ülkeleri temiz, yenilenebilir, çevre dostu alternatif enerji kaynaklarına yönelmeye sevk etmiştir. Bu alternatif enerji kaynaklarından bir tanesi de bitkisel yağ, hayvansal yağ ve bunların kullanılmış olanlarından üretilen biyodizeldir. Bu tez çalışmasında ilk kısımlarında alternatif enerji kaynaklarından bahsedilmiştir. Çalışmanın sonraki bölümünde ise biyodizel üretim teknolojilerinden bahsedilmiş, biyodizel üretim süresince yaşanan sorunlar ve çözüm yöntemleri üzerinde durulmuştur.
