Galatella rossica is endangered plant species included in the Red Data Book of the Republic of Mordovia (Central Russia). In the region, it is known from six micropopulations. None of them is located within the regional protected areas network. We have carried out the study of abundance dynamics for two of the known populations: for location 1 –between 2009-2013–, for location 2 –between 2004-2013–. We established that the number of individuals in both studied populations has decreased. It was caused by processes of afforestation and overgrowing in habitats by tall vegetation and shrubs (e.g., Salix spp., Spiraea crenata). We suggest the resumption of more detail population-based studies in the region.

Resumen Los estudios poblacionales de especies de plantas vulnerables brindan importante información sobre sus preferencias ecológicas y condiciones ambientales de sus hábitats. Galatella rossica es una especie de planta en peligro incluida en el Libro Rojo de la República de Mordovia (Rusia Central). Se conocen seis micropoblaciones en esta región. Ninguna de ellas se ubica dentro de la red regional de áreas protegidas. Hemos llevado a cabo el estudio de la dinámica de la abundancia en dos de las poblaciones conocidas: en la ubicación 1 –entre 2009 y 2013–, en la ubicación 2 –entre 2004 y 2013–. Determinamos que el número de individuos en ambas poblaciones estudiadas ha disminuido. Esto fue causado por procesos de reforestación y sobrecrecimiento de vegetación alta y arbustos en sus hábitats (p. ej. Salix spp., Spiraea crenata). Sugerimos la reanudación de estudios de población más detallados en la región.

Introduction Galatella rossica Novopokr. is one of three Galatella species known in the Republic of The genus Galatella Cass. includes Mordovia. This is perennial plant 25–150 between 30 and 45 species distributed mainly cm. Numerous stems erect, covered by throughout Europe, Russia, Iran, and from short hairs. Leaves sessile, linear-lanceolate, India to western China (Ling et al., 1985; glandular-punctate, 8 mm in width and up Nesom & Robinson, 2007; Tzvelev, 1959). to 10 cm in length. Anthodes 7–12 mm in Its main centre of diversity is located within length and 8–12 mm in width. Disk flowers Eastern Europe and Russia. Although main are jonquil-yellow, ray flowers – pinkish- systematic studies of the tribe invariably purple. Fruits – achenes with albescent argued for the independence of the genus pappus (Ignatov, 2014; Merxmüller & Galatella with respect to the genus Aster Schreider, 1976; Tzvelev, 1994). According (Ling et al., 1985; Nesom, 1994a,b; Nesom to different sources this species is named & Robinson, 2007; Tzvelev, 1959), this as Galatella sedifolia (L.) Greuter (Greuter, viewpoint remains debatable in regional 2003), G. punctata (Waldst. et Kit.) Nees and national floras of Europe and Asia (Ignatov, 2014), Aster sedifolia L. subsp. (Brouillet et al., 2009; Ekim, 2012; Ignatov, sedifolius (Merxmüller & Schreider, 1976). 2014; Nesom & Robinson, 2007). We use the name Galatella rossica Novopokr. 240 24 (1): Enero - Junio, 2017 Khapugin & Kunaeva: Abundance dynamics of endangered species Galatella rossica (Asteraceae) in the Republic of Mordovia: Short Report in consistent with a synopsis flora of the species (Chau et al., 2013; Khapugin & Republic of Mordovia (Silaeva, 2010). Chugunov, 2015). Here we report the result of population-based survey of Galatella This species is known from most regions rossica in one of its locations within the of Central Russia, being rare to north. In Republic of Mordovia (Central Russia). Mordovia, it was included in regional Red Data Book with category 3 “Rare species” Material and methods (Resolution, 2015) being known from 6 local populations (Fig. 1). All of them are We investigated two closely located located in the eastern part of Mordovia, micropopulations on flood meadows in primarily along the Sura river. All G. Bolshie Berezniki district of the Republic rossica populations are located outside of of Mordovia near the boundary with the established regional Protected Areas Ulyanovsk Region (Fig. 1). First of them is Network (Khapugin et al., 2017b). As a result a population near lake Belyaevka (location of long-term studies of rare and endangered 1: 54.166 N, 46.152 E). Vegetation cover is plants in the Republic of Mordovia, all presented primarily by representatives of species from regional Red Data Book were families Fabaceae and Poaceae. The bushes of estimated according to IUCN Red List Salix spp. (primarily – Salix cinerea L.) and Categories and Criteria (IUCN 2012a,b, Acer tataricum L. are located around this 2014). Amongst them, Galatella rossica was flood meadow. Second micropopulations assessed as an Endangered taxon (Khapugin is located near the former pioneer camp et al., 2017a). “Zelenaya Polyana” (location 2: 54.177 N, 46.183 E). Here, Galatella rossica population Long-term monitoring of plant is situated at the forest edge. Stand of populations often provides significant nearby forest is presented by Quercus robur data about influence main factors on their L., Ulmus glabra Huds.; shrub layer consists vitality and status (Čtvrtlíková et al., 2016; of Acer tataricum (striving to reach the first Khapugin et al., 2016a; Trowbridge et al., layer), Populus tremula L., Padus avium Mill., 2016; Webster et al., 2005), especially, it Frangula alnus Mill. concerns peripheral populations of plant Fig. 1. Situation of the Republic of Mordovia in Eastern Europe. Studied Galatella rossica populations are designated by circles, other regional populations are marked by squares (Map with modifications from web-site United Nations Geospatial Information Section: http://www.un.org/Depts/Cartographic/english/htmain.htm). 24 (1): Enero - Junio, 2017 241 Khapugin & Kunaeva: Abundance dynamics of endangered species Galatella rossica (Asteraceae) in the Republic of Mordovia: Short Report During vegetative seasons of 2009-2013, individuals in location 1 has increased we have carried out estimation of abundance from 2009 to 2010 in the first year of study dynamics of Galatella rossica individuals in when vegetation cover has been influenced location 1, and during 2004-2013 in location by extremely dry season (Fig. 2). Due to 2. For this purpose, we have counted total oppression state of main competitors, number of individuals in each studied Galatella rossica has increased its own location. In order to count the abundance abundance in location 1. However, in next of individuals in each population, each years its abundance has decreased till 147 aboveground shoot was considered as one individuals in 2013 (minimal value over all individual. study period). Results and discussion This decline of abundance was caused by decrease of grazing and haymaking impacts As a result of conducted investigations, on this flood meadow. As a consequence, we found that abundance of Galatella rossica Fig. 2. Abundance dynamics of individuals in Galatella rossica population near the lake Belyaevka (location 1) during 2009–2013. shrub vegetation became to overgrow in compare with location 1 (the largest those areas. As a result Galatella rossica number of individuals reached 1424 units could not compete with shrubs and tall in 2008), we have observed that Galatella herbaceous vegetation; and its population rossica plants located directly near the forest area gradually had declined. canopy (under shadiness impact) differed by lower vitality. This was reflected in In location 2, in the year 2013 Galatella lower height of individuals and anthode’s rossica population was presented by the diameter; the flowering stage of these smallest number of individuals over a plants has begun earlier
