“…Other regions, however, seem to have less endangered sites in comparison to Eastern Poland. Sikorska and Wolnicki (2011) indicated only one site in the Wielkopolskie voivodeship, and Wolnicki et al (2011c) found two sites in the Kujawsko-Pomorskie voivodeship classified as critically threatened. Generally, at least 75% of habitats of lake minnow are currently in danger of being destroyed (Kaczmarczyk and Wolnicki 2016).…”

“…In Poland, there are about 160 sites distributed non-uniformly in five voivodeships: Pomorskie, Wielkopolskie, Kujawsko-Pomorskie, Mazowieckie, and Lubelskie (Radke et al 2011, Sikorska et al 2011, Wolnicki et al 2011a, b, c). The vast majority of the sites are found in the Pomorskie Voivodeship and in the Lubelskie Voivodeship (Wolnicki et al 2011a).…”

In Poland, lake minnow ( Eupallasella percnurus Pall.) inhabit 160 sites, including 44 in the eastern part of the country. Their habitats are mainly small and shallow peat holes vulnerable to complete destruction due to being dried or overgrown. Such processes are regularly observed, with ~ 60% of sites having vanished since the 1950s. Therefore, this species is one of the most endangered fish species from the Cyprinidae family in Polish inland waters. A GIS approach was adopted to fully analyze their habitat loss. The habitat area was marked in four time periods (from the 1960s to 2018) in reference to 26 sites composed of 111 reservoirs and representing almost 60% of all those documented in Eastern Poland. On this basis, the rate at which the habitat will vanish and the predicted time when this will happen were calculated. The results showed that the mean vanishing rate oscillates between 1 and 2% of the area per year for 50% of the analyzed sites ( N = 13). For three sites (11%), this value does not exceed 1% of each area per year and is higher than 2% for the rest of the sites (39%). The results indicate that if the process of overgrowing and shallowing is not stopped, 58% of the analyzed sites will disappear in the next 50 years (including 8 (31%) in the next 20 years). This trend may lead to a serious decline in the species population or even its extinction in the next decades. Passive protection has proven to be insufficient in preserving lake minnow habitats. Therefore, there is an urgent need to undertake decisive protection action, as proposed in this manuscript.

“…Among the 165 sites known in Poland, over 120 are under threats of anthropogenic or natural origin, in particular swamp draining, amelioration, deforestation and infilling. Most of the historic sites have disappeared over the last two decades (Wolnicki et al , ). Eupallasella percnurus is included among the animal species with the highest priority in the Natura 2000 European Ecological Network, in the group of species that requires active protection measures (Radtke et al , ).…”

Characterization of lake minnow Eupallasella percnurus semen in relation to sperm morphology, regulation of sperm motility and interpopulation diversity

Sperm morphology and regulation of sperm motility of lake minnow Eupallasella percnurus, an endangered cyprinid, were investigated. Milt characteristics from two isolated populations of E. percnurus were compared to characterize the interpopulation diversity. Electron microscopic studies revealed that E. percnurus spermatozoa comprise simple, uniflagellate, anacrosomal aquasperm with species-specific features as an eccentrically located implantation of nuclear fossa and eccentric insertion of flagellum. Sperm motility was significantly inhibited by relatively low ion concentrations (150, 150 and 8 mM for NaCl, KCl and CaCl2 , respectively). Sperm maintained a high motility rate over a wide pH range (5.5-10.5), which may reflect adaptation to a highly variable environment. The two E. percnurus populations were markedly different in milt volume, sperm concentration, seminal plasma pH, sperm motility and beat cross frequency, which may result from genetic differences and environmental conditions.

“…Consequently, almost 50% of the sites in this region are considered to be threatened to low degree (Table 1). In other voivodeships the share of such sites is generally lower (Wolnicki and Radtke 2009, 2010, Radtke et al 2011, Wolnicki et al 2011a, 2011b.…”

Abstract. This paper presents updated information on the past and present occurrence of the endangered cyprinid lake minnow, Eupallasella percnurus (Pall.), in Lubelskie Voivodeship in Poland. It includes an approximate assessment of threats to its existence and perspectives for its protection. The area of today's voivodeship was the largest national sanctuary for this species as early as in the 1950s; however, of 52 known historical sites, only seven are currently extant. Wide-ranging field inventories conducted in the voivodeship in 2002-2010 revealed the existence of 40 previously unknown sites. The present state of E. percnurus occurrence was assessed for 44 sites, nearly half of which are located in the Dorohuskie Depression mesoregion around the
