Abstract BackgroundGeographic differences in flower size sometimes reflect geographic differences in pollinator size. However, we know little about whether this flower size specialization to the regional pollinator size occurred independently at many places or occurred once and then spread across the distribution range of the flower species. ResultsWe investigated the relationship between the local corolla tube length of flowers and morphological traits of local pollinators in 12 populations of Lamium album var. barbatum on two different mountains in the Japan Alps. Then, using 10 microsatellite markers, we analyzed genetic differentiation among the 12 populations. The results showed that local corolla tube length was correlated with the average size of relevant morphological traits of the local pollinators: corolla tube length was greater in populations visited frequently by the largest flower visitors, Bombus consobrinus queens, than it was in other populations. We also found that the degree of genetic similarity between populations more closely reflected interpopulation geographic proximity than interpopulation similarity in corolla tube length.ConclusionsAlthough genetic similarity of populations was highly associated with geographic proximity, corolla tube length varied independently of geographic proximity and was associated with local pollinator size. These results suggest that in L. album var. barbatum, long corolla tube length evolved independently in populations on different mountains as a convergent adaptation to locally abundant large bumblebee species.

Изучение растительности городов имеет и теоретическое и практическое значение. Для Санкт-Петербурга имеются публикации лишь по некоторым районам. Классификация растительности является экологической основой ухода за зелеными насаждениями города. Парк Политехнического университета начал формироваться на месте сосняков брусничных и черничных на песчаных отложениях одновременно со строительством университета в 1900 г. Парк находится под воздействием атмосферного загрязнения, в районе наблюдалось выпадение 192–200 кг/гагод оксидов азота (в пересчете на азот). Информацию о растительных сообществах собирали на пробных площадях размером 2020 м. По данным 35 описаний выделены березовая с тремя ассоциациями и сосновая формации с пятью ассоциациями. В живом напочвенном покрове чаще других доминирует сныть – Aegopodium podagraraia, реже гравилат городской – Geum urbanum, ежа сборная – Dactylis glomerata, костер безостый – Bromopsis inermis, крапива двудомная – Urtica dioica, луговик извилистый – Avenella flexuosa, виды устойчивые к вытаптыванию (мятлик однолетний – Poa annua, подорожник большой – Plantago major). Содоминантами и константными являются виды сорно-судубравной группы (Aegopodium podagraraia, Antriscus sylvestis, Geum urbanum, Glechoma hederacea, Lamium album, Stellaria media, Urtica dioica). Насаждения парка растут на дерново-подбурах, более плодородных (БЗ по Раменскому – 7,5–11,5), чем загородные леса на наиболее богатых дренированных местообитаниях (дубравнотравная серия типов леса, БЗ – 7,0–7,5), а тем более сосняки брусничные (БЗ – 3,3–4,6), на месте которых возник парк. Это объясняется загрязнением почв оксидами азота. The study of the vegetation of cities has both theoretical and practical significance. For the city of St. Petersburg, there are publications only on some areas. Classification of vegetation is an ecological basis for the care of the green plantations of the city. The park of the Polytechnic University was found on the place of bilberry- rich pine forest on sand deposits simultaneously with the construction of the University in 1900. The park is under the influence of atmospheric pollution, with a fall of 192 to 200 kg/haper year of nitrogen oxides (in amount of nitrogen). Information on plant communities was collected on sample plots 2020 m each. According to 35 revelés, birch with 3 associations and pine formations with 5 associations were distinguished. In the ground cover, most often dominate the obscure – Aegopodium podagraraia, less often urban gravel – Geum urbanum, hedgehogs – Dactylis glomerata, boneless beet – Bromopsis inermis, nettle – Urtica dioica, wavy hair grass – Avenella flexuosa, species resistant to trampling (Poa annua annual – grasshopper, Plantago major – plantain). Codominant and constant are species of the weed-subnemoral group (Aegopodium podagraraia, Antriscus sylvestis, Geum urbanum, Glechoma hederacea, Lamium album, Stellaria media, Urtica dioica). The forests of the park grow on more fertile soils (FS – fertile-salinity index after Ramenskiy, 7.5–11.5) than the suburban forests of the most rich drained habitats (nemoral series of forest types, FS 7.0–7.5), and more fertile that soils of pine bilberry (FS 3.3–4.6) forests, in the place of which the park appeared. This is due to nitrogen contamination.
