Contribution to bee fauna (Hymenoptera: Apoidea: Anthophila) of Poland. VII. The genus Andrena Fabricius, 1775. Part 3

Ecological amplitude and indication potential of mining bees (Andrena spp.): a case study from the post-agricultural area of the Kampinos National Park (Poland)

“…Its presence might due to climate change, as the records in KNP are at the northernmost part of its range. Furthermore, the occurrence of Andrena gallica in Poland was also confirmed after more than 50 years, based on a specimen collected in KNP 34 .…”

“…Information on: habitat preferences is marked by number preceding species name (1—eurytopic, occurring from lowlands to high mountains, both in open and forested areas; 2—polytopic, inhabiting wide range of habitats but preferring either open or forested areas; 3—oligotopic, associated with particular types of habitats, mostly dry and on sand or of steppe character), nesting preferences connected with soil moisture is marked by the letter preceding the species name (a—dry, b—dry and moderately moist, c—moderately moist, d—moderately moist and moist). Categories of threat according to verified list of threatened species 10 , 34 : CR—critically endangered, EN—endangered, VU—vulnerable, NT—near threatened, LC—least concern, DD—data deficient, remaining species—not threatened.…”

“…The verified list of threatened Andrena species in Poland, based on Motyka 10 and Wiśniowski et al 34 , shows that 19 mining bee species (41%) recorded in the KNP are threatened, namely one species has the category CR ( Andrena gallica ), one species has the category EN ( A . symphyti) , seven species are assigned as VU and 10 species as NT (Table 6 ).…”

“…The Red List of Vanishing and Endangered Animals in Poland in 2002 included half of the species recorded in the country 33 , with most of these records assessed as Data Deficient. The list of the genus Andrena was more preliminary in character, because no species was listed in the categories EX/RE (extinct/regionally extinct) or CR (critically endangered), although some taxa were not recorded in Poland for a relatively long period of time 34 . According to the verified Red List of the genus Andrena 10 , over 87% of the species that occur in the country are more or less endangered.…”

“…An updated Red List of threatened wild bees in Poland is clearly necessary. In selected Andrena species, verification of their threat status has mostly led to the reclassification of the species into higher categories of threat 10 , 34 compared to the previous Red List 33 .…”
