Leaf area of meadow plants under regimes of mowing and protection in the Central Forest Reserve

Abstract

3, gentiana07@yandex.ru 4 Аннотация. Площадь листа и удельная листовая поверхность (УЛП) измерены у 16 видов травянистых растений на косимых и выведенных из использования лугах Центрально-Лесного заповедника (Тверская область). У 12 из 16 изученных видов сенокошение не влияло на эти признаки. У Agrostis tenuis и Plantago lanceolata уменьшилась пло-щадь листа, и увеличилась УЛП на заповедных участках. У Rumex acetosa на заповедных участках увеличилась пло-щадь листьев, а УЛП не изменилась. Участие видов в сообществе не было скоррелировано с площадью листьев и УЛП. Таким образом, сенокошение, по-видимому, не влияет на отбор по этим функциональным признакам.Ключевые слова: площадь листа, удельная листовая поверхность, луга, сенокошение, заповедный режим.Abstract. Leaf area and specific leaf area (SLA) of 16 herbaceous plant species were studied on the mown and abandoned meadows of the Central Forest Reserve, Tver`region. In 12 of 16 studied species, there was no significant impact of mowing to these traits. Agrostis tenius and Plantago lanceolata decreased leaf area and increased specific leaf area on the abandoned sites, Rumex acetosa increased leaf area on the abandoned sites without changes in SLA. Species number in the community was not related to their leaf area and SLA, thus mowing probably has no impact on selection by studied traits.

Vascular plant occurrences in grasslands of Central Forest Nature Reserve (Russia): a dataset

“…The flora and phenology of the Central Forest Reserve were actively studied ( Minayev and Konechnaya 1976 , Konechnaya 2012 , Shuyskaya 2018 , Zorina et al 2020 ), but the works describing the vegetation of the Reserve predominantly focused on the forests and the raised bogs ( Karpov 1983 , Kurayeva et al 1999 , Minaeva et al 2007 , Minaeva 2010 , Korablev et al 2018 ). Therefore, there are few publications concerning the grassland vegetation of the Reserve ( Elumeeva et al 2017 , Cherednichenko and Borodulina 2018 , Cherednichenko et al 2021 , Elumeeva et al 2017 Elumeeva et al 2021 ). Only the paper of Cherednichenko and Borodulina (2018) focused on the diversity of grasslands in the Reserve.…”

“…In this data paper, we describe the dataset providing the basis for identifying four grassland types in the Reserve (managed mesic, abandoned mesic, subruderal mesic and wet grasslands); this dataset is published for the first time. The other three papers focused on functional traits of leaves ( Elumeeva et al 2017 ) and phytomass of two grassland types (managed mesic and abandoned mesic grasslands) ( Cherednichenko et al 2021 ), as well as on the decomposition rate of standard material in grassland soils (Tea bag index) ( Elumeeva et al 2021 ).…”
