No full textAllium izmirense Pirhan, sp. nov. (Amaryllidaceae) est décrit ici comme une nouvelle espèce. Les caractères morphologiques diagnostiques, une description complète, et des illustrations détaillées sont fournis. Allium izmirense Pirhan, sp. nov. est limité au mont Güme, une partie des monts Aydın, près du district de Tire (province d’İzmir, Anatolie occidentale, Turquie). D’après ses caractéristiques morphologiques, le taxon nouveau appartient à la section Codonoprasum du genre Allium. Il présente des similitudes morphologiques avec A. carlstroemi C. Catt., A. stamineum Boiss., A. armenum Boiss., A. tchihatschewii subsp. dumanii (Koyuncu & Koçyigit) Yild., A. hoshabicum Fırat et A. huber-morathii Kollman, qui appartiennent à la même section. Allium izmirense Pirhan, sp. nov. est un proche parent de A. carlstroemi. Il se distingue facilement de cette espèce par sa tunique externe papyracée, ses feuilles cylindriques et pubescentes, ses gaines foliaires sur 1/3-1/2 de la longueur de la tige, ses spathes à valves courtes de 0,5-1,4 cm de long, à valves plus longues de 1,4-3(-6) cm de long, ses pédicelles de 0,5-1,5 cm de long, son tépale rose pourpre, à nervure médiane distincte, de 2,5-3,5 mm de long, son style de 2-3 mm de long. Selon les critères de l’UICN, A. izmirense Pirhan, sp. nov. est suggéré comme étant en danger critique d’extinction (CR) B2ab (ii, iii, v).Allium izmirense Pirhan, sp. nov. (Amaryllidaceae) is described here as a new species. Diagnostic morphological characters, a full description, and detailed illustrations are given herein. Allium izmirense Pirhan, sp. nov. is restricted to Mt. Güme, a part of the Aydın Mountains series near the Tire District of İzmir Province in western Anatolia, Turkey. According to its morphological features, it belongs to Allium sect. Codonoprasum. It shows morphological similarities to A. carlstroemi C. Catt., A. stamineum Boiss., A. armenum Boiss., A. tchihatschewii subsp. dumanii (Koyuncu & Koçyigit) Yild., A. hoshabicum Fırat, and A. huber-morathii Kollman, which belong to the same section. Allium izmirense sp. nov. is close related to A. carlstroemi. It is easily distinguished from this species mainly by its outer tunic papyraceous; cylindrical and pubescent leaves; leaf sheaths for 1/3-1/2 of the stem length; spathe shorter valves 0.5-1.4 cm long, longer valves 1.4-3(-6) cm long; pedicels length 0.5-1.5 cm; tepal pinkish purple, with distinct midrib, length 2.5-3.5 mm; style 2-3 mm long. According to the IUCN criteria A. izmirense Pirhan, sp. nov. is suggested as Critically Endangered (CR) B2ab (ii,iii,v).</p

Chaenorhinum semispeluncarum sp. nov. and C. yildirimlii sp. nov. (Scrophulariaceae) from east Anatolia, Turkey
No full textChaenorhinum semispeluncarum H. Yildirim, Kit Tan, S. Şenol & A. Pirhan sp. nov. and C. yildirimlii Kit Tan, H. Yildirim, S. Şenol & A. Pirhan sp. nov. (Scrophulariaceae, C. sect. Microrrhinum) from east Anatolia are described and illustrated. They are both narrow endemics related to the rare C. cryptarum, also from east Anatolia. Chaenorhinum semispeluncarum occurs on calcareous marl rich in potassium nitrate at the entrance of wet caves in Malatya and differs from C. cryptarum by its erect habit, smaller corollas, shallowly ribbed and tuberculate, bicoloured seeds. Chaenorhinum yildirimlii from the neighbouring province of Erzincan was found on alluvial soil of stream banks and differs from C. semispeluncarum by its seed characters which are similar to those of C. cryptarum. Chaenorhinum yildirimlii differs from C. cryptarum, most conspicuously by the violet lower corolla lip spotted dark purple at the apex. © 2010 The Authors

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
