Hover Fly and you will Bee Travel Variety Variety
Bee Variety Range
Of 2009 so you’re able to 2018, 192 bee species (Hymenoptera: Apoidea: Anthophila) was caught during the Calanques National Playground through both internet and you may pan pitfall selections. They belonged to half a dozen family and you will 38 genera. Megachilidae are the essential variety-steeped members of the family, with Apidae and you can Halictidae, having 53, forty-two, and you will 43 species, respectively. Andrena Fabricius, 1775 was the latest richest genus, which have 33 kinds, while eight genera was indeed portrayed because of the just one species (Stelis Panzer, 1806; Protosmia Ducke, 1900; Pseudoanthidium Friese, 1898; Coelioxys Latreille, 1809; Chelostoma Latreille, 1809; Anthidiellum Cockerell, 1904; Amegilla Friese, 1897; Panurgus Panzer, 1806; Supp Desk step one [on line just] ). Using the jackknife step one and you will 2 indexes, the entire bee variety fullness was projected as ranging from ± 9.89 and you can ± . Brand new noticed fullness ergo represented 71.step 3 to 79.6% of projected bee richness ( Desk dos). The new Chao1 method projected new seen fullness are 76.8% of prospective limitation richness ( Table dos). One particular plentiful kinds try Apis mellifera L. (276 individuals), followed closely by Rhodanthidium septemdentatum (Latreille, 1809), Rh. sticticum (Fabricius, 1787) (174 and 168 people, respectively), and you will Lasioglossum transitorium (Shenck, 1868) (113 anyone). Eventually, fifty variety (26%) was in fact represented of the one individual (singletons).
Ecological Qualities out-of Bees
Regarding the environment qualities from nesting tastes, i known 59 unmarried bee varieties nesting above floor, ninety-five unmarried bee variety nesting below ground and you may 23 cleptoparasitic types, add up to 29.7, 47.nine, and you may several.0% of full bee kinds richness, respectively. I observed four social kinds (bumble bees local sex hookup sites and you can honey bees-dos.1%). Ultimately, the newest nesting choices out of fourteen kinds are unfamiliar (7.3%- Supp Desk step one [online only] ). About your floral eating plan from bee varieties, we found that 105 kinds (54.7%) foraged into many plant variety (i.e., generalist types, polylectic) and you may 51 species (twenty-six.5%) foraged on one bush nearest and dearest otherwise one to/pair bush variety (we.age., pro types, oligolectic). With the left thirty-six bee varieties (18.8%), brand new flowery eating plan wasn’t understood (age.g., to possess cleptoparasitic varieties). However, extremely generalist species exhibited an inclination for just one otherwise a number of plant family members ( Supp Dining table 1 [on the internet simply] ). Towards forty-two singletons, 14 bee variety (28%) were professionals, and you can nine bee kinds (18%) was cleptoparasitic ( Supp Dining table step 1 [on the internet only] ).
An IUCN updates is actually available for 178 types (excluding new types complexes and you will not known kinds). Those types of, 47 variety was indeed categorized just like the investigation deficient (DD-26.4%), 124 varieties have been minimum alarmed (LC-69.6%), half dozen variety were near threatened (NT-3.4%; Andrena ovatula (Kirby, 1802), Colletes albomaculatus (Lucas, 1849), Dasypoda argentata Panzer, 1809, Halictus quadricinctus (Fabricius, 1776), Lasioglossum prasinum (Smith, 1848), and you may L. pygmaeum (Schenck, 1853)), and something variety are noticed endangered (EN-0.6%; L. soror (Saunders, 1901)- Supp Table step one [on the internet simply] ). Three oligolectic variety was in fact among 7 endangered bee kinds. A great. ovatula and C. albomaculatus is gurus towards Fabaceae, D. argentata was a professional with the Caprifoliaceae.
Out of 2009 to help you 2018, 38 types of hover flies (Diptera: Syrphidae) was caught when you look at the Calanques National Playground. It belonged so you’re able to twenty-four genera ( Supp Dining table dos [online just] ). Many plentiful genera was in fact Paragus Latreille, 1804 (33 some one), Meliscaeva Frey, 1946 (fourteen anyone), and Sphaerophoria Lepeletier de- Saint-Fargeau Audinet-Serville within the Latreille, 1828 (13 anyone), while 20 variety (53%) was indeed portrayed by the just one private ( Supp Table 2 [on the web merely] ). The new bee flies (Diptera: Bombyliidae) had been represented of the 20 varieties, in addition to five singletons (25%) ( Supp Desk step three [on the web just] ). The estimation out of complete species richness from hover flies and you will bee flies is between 83 and 97 species using the jackknife step 1 and you may dos spiders, respectively. Therefore, the new seen fullness depicted 59.8–69.9% of the estimated hover fly and bee travel richness ( Table 2).
