    Alien flora of Turkey: checklist, taxonomic composition and ecological attributes
    (Pensoft Publishers, 2017) Uludağ, Ahmet; Aksoy, Necmi; Yazlik, Ayse; Arslan, Zubeyde Filiz; Yazmis, Efecan; Uremis, Ilhan; Cossu, Tiziana Antonella
    The paper provides an updated checklist of the alien flora of Turkey with information on its structure. The alien flora of Turkey comprises 340 taxa, among which there are 321 angiosperms, 17 gymnosperms and two ferns. Of the total number of taxa, 228 (68%) are naturalized and 112 (32%) are casual. There are 275 neophytes (172 naturalized and 103 casual) and 61 archaeophytes (52 naturalized and 9 casual); four species could not be classified with respect to the residence time. In addition, 47 frequently planted taxa with a potential to escape are also listed. The richest families are Asteraceae (38 taxa), Poaceae (30), Fabaceae (23) and Solanaceae (22). As for the naturalized alien plants, the highest species richness is found in Asteraceae (31 taxa), Poaceae (22), Amaranthaceae (18) and Solanaceae (15). The majority of alien taxa are perennial (63.8% of the total number of taxa with this life history assigned, including those with multiple life histories), annuals contribute 33.8% and 2.4% are biennial aliens. Among perennials the most common life forms are phanerophytes, of which 20.3% are trees and 12.6% shrubs; woody vines, stem succulents, and aquatic plants are comparatively less represented. Most of the 340 alien taxa introduced to Turkey have their native ranges in Americas (44.7%) and Asia (27.6%). Of other regions, 9.1% originated in Africa, 4.4% in Eurasia, 3.8% in Australia and Oceania and 3.5% in the Mediterranean. The majority of taxa (71.9%) were introduced intentionally, whereas the remaining (28.1%) were introduced accidentally. Among the taxa introduced intentionally, the vast majority are ornamental plants (55.2%), 10.0% taxa were introduced for forestry and 6.7% as crops. Casual alien plants are most commonly found in urban and ruderal habitats (40.1%) where naturalized taxa are also often recorded (27.3%). Plants that occur as agricultural weeds are typically naturalized rather than casual (16.0% vs 7.1%, respectively). However, (semi) natural habitats in Turkey are often invaded by alien taxa, especially by those that are able to naturalize.

    Biological weed control
    (Elsevier, 2018) Uludağ, Ahmet; Uremis, Ilhan; Arslan, Mehmet
    The biological approach, as an integral part of integrated and sustainable weed control approaches, has an increasing importance and consideration due to increasing environmental and anthropogenic problems. Successful weed control through use of biological agents has a background of more than a couple of centuries. In this chapter, we started with a more classical way of biological approach to introduce arthropods, mainly insects, followed by examples of redistribution of local arthropods. In the bioherbicide section, we have focused on formulated natural products and formulations. Biological weed control faces problems such as inadequacy of finance, some side effects, and conflicting views. However, biological methods are expected to provide more promising weed control practices in the future. © 2018 Elsevier Inc. All rights reserved.

    The Possible Role of Bird Migrations on Introduction and Spread of Invasive Alien Plants: A Case Study, Solanum elaeagnifolium Cav.
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2024) Uludağ, Ahmet; Uremis, Ilhan; Kozbas, Ayseguel Iliker; Soylu, Soner; Erkilic, Lerzan Bakircioglu; Ilcim, Ahmet
    Solanum elaeagnifolium (SOLEL), a native plant of the Americas is a highly spread invasive alien species worldwide with impacts on biodiversity and agriculture. It has a long history in Mediterranean basin and the Middle East where Turkiye is located but there was no record except one in 2006 from the eastern the Mediterranean of Turkiye of which introduction was attributed to migrating birds. Despite widespread and large populations in neighboring countries, not detecting SOLEL in Turkiye had been questionable. The aims of the study were to find out new populations of SOLEL in Turkiye and understand the reason of less population occurred in Turkiye. Two areas were selected near the country borders of Turkiye which are known as migrating bird routes. Areas were visited unregularly several times from 2020 to 2023 to find out SOLEL populations. New populations were detected in the eastern Mediterranean and Aegean Regions of Turkiye which are over 1000 km apart from each other. SOLEL populations and bird migration routes through Turkiye and countries SOLEL has already been recorded were compared. It is concluded that SOLEL might be introduced by migrating birds. It is suggested that more detailed research is needed to explain the role of migrating birds in invasive alien plants' introductions. Furthermore, plants around wetlands which birds use in their migration routes should be observed to prevent new plant invasions.

    Weed species in banana (Musa spp.) production systems in Turkiye
    (Soc Brasileira Ciencia Plantas Daninhas-Sbcpd, 2023) Torun, Hilmi; Ozkil, Mine; Uremis, Ilhan; Uyar, Sevgi; Uludağ, Ahmet
    Background: Banana (Musa spp.) cultivation, has a centaury history in open fields in Mediterranean part of Turkiye has become enlarged for three decades due to benefits of covered production. Objective: Weed species, their frequencies, distributions and reasons under current techniques and geographical attributes in banana fields and greenhouses were determined to provide data to develop strategies and systems for sustainable weed management and cultivation of banana. Methods: Weeds and their coverage and densities were determined in banana fields and greenhouses surveying 2% of banana production acreage in 2021-2022. Results: 68 different species of 25 families were recorded. The most common weed species were Cardamine occulta, Amaranthus retroflexus, Portulaca oleracea, Conyza canadensis, and Oxalis corniculata. The number of weeds, their coverage and densities in individual fields were not affected significantly by production method (open-field vs greenhouse) or banana cultivars but location. Years and field size affected the number of weed species while homogeneity and cycles affected weed coverage and density. Dominant species in greenhouses were C. occulta, Pilea microphylla, O. corniculata, Echinochloa crus-galli, Setaria verticillata, and A. retroflexus but Cyperus rotundus, S. verticillata, O. corniculata, and P. oleracea in open fields. C. occulta and Pilea microphylla were recorded first time in Turkiye. Conclusions: The most common species and dominant species in fields are mainly aliens including both neophytes and archeophytes. Greenhouses and production techniques might have effect on weed problem. There are needs for further research on banana weeds including their controls to establish better strategies and control systems in banana management.
