Overall, we discovered 61 symbiotic species, comprising 17 specialized obligate species and 44 generalists (facultative species and species with uncertain status). The total species richness, mean species number and mean abundance per colony were significantly higher in the lagoon than in the forereef, likely due to their respective temperature regimes. The lagoon is characterized by more frequent thermal anomalies than the forereef is, causing greater coral bleaching. This higher frequency of thermal stress apparently results in frequent renovations of coral-symbiotic communities following post-bleaching coral re-covery, which seem to be associated with the increased diversity of commensal fauna and, particularly, with the abundance of facultative symbionts. symbiotic communities from different environments of an isolated atoll: reef lagoon versus forereef // Invert.

More species (5 vs 3) and higher abundance levels (123 vs 86) were observed in the cooler and rainy 2016 compared to the warmer and drier 2021, with the incidence of occurrence varying between ca 74% and ca 66%, respectively. The nests were dominated by Ommatoiulus sabulosus , while Leptoiulus proximus subdominated, during both years of monitoring. Together with the remaining few species of Diplopoda encountered in Pied flycatcher nests there, they can only be considered as purely opportunitic nidicoles. No obligate nidicoly in Karelian Diplopoda could be suggested, facultative nidicoly being common instead.","PeriodicalId":37977,"journal":{"name":"Invertebrate Zoology","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85703740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, we compared P. jaenensis from the studied locality with P. rupestris according to the shell shape by means of geometric morphometric methods. The analysis of the Thin-Plate Spline graph showed that P. jaenensis presented an expansion on the growth to the first whorls and the apex, whereas the height of the body whorl was moderately contracted, while in P. rupestris the opposite was found. We found significant differences between both species based on shell shape.

Both species are morphologically close to the Transcaucasian species, especially P . linearis (Birstein, 1967), but can be easily distinguished by several characters. P . uallagirus sp.n. differs in shape of pleopodes, size ratio of pleopod exopodites and endopodites, and arming of internal surface of the pereopod I propodus. P . irystonicus sp.n. also differs in arming of pereopods I–VII dactiluses.
