20.500.12556/DiRROS-23952 Lizard host abundances and climatic factors explain phylogenetic diversity and prevalence of blood parasites on an oceanic island 1. Host abundance might favour the maintenance of a high phylogenetic diversity of some parasites via rapid transmission rates. Blood parasites of insular lizards represent a good model to test this hypothesis because these parasites can be particularly prevalent in islands and host lizards highly abundant. 2. We applied deep amplicon sequencing and analysed environmental predictors of blood parasite prevalence and phylogenetic diversity in the endemic lizard Gallotia galloti across 24 localities on Tenerife, an island in the Canary archipelago that has experienced increasing warming and drought in recent years. 3. Parasite prevalence assessed by microscopy was over 94% and a higher proportion of infected lizards was found in warmer and drier locations. A total of 33 different 18s rRNA parasite haplotype were identified and the phylogenetic analyses indicated that they belong to two genera of Adeleorina (Apicomplexa: Coccidia), with Karyolysus as the dominant genus. The most important predictor of between-locality variation in parasite phylogenetic diversity was the abundance of lizard hosts. 4. A combination of climatic and host demographic factors associated with an insular syndrome may be favouring a rapid transmission of blood parasites among lizards on Tenerife, which may favour the maintenance of a high phylogenetic diversity of parasites. lizards parasites genetics biogeography habitat data plazilci paraziti genetika biogeografija habitat podatki Gallotia galloti Adeleorina true false true Mendeley, Elsevier Angleški jezik Slovenski jezik Neznano 2025-10-27 11:43:41 2025-10-27 11:43:41 2025-10-28 03:41:56 0000-00-00 00:00:00 2023 0 [London] 2023 [London] Nasl. z. nasl. zaslona; Opis vira z dne 14. 8. 2025; Soavtorji: Gemma Palomar, Javier Martinez, Bernardo Antunes, Katarzyna Dudek, Anamarija Zagar, Nina Serén, Miguel Carretero, Wieslaw Babik, Santiago Merino; 1 spletni vir 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-08-04 591 10.17632/v4w54r7snd.1 245753603 https://doi.org/10.1111/mec.17276 0 d0b58ae4-b321-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35563 https://doi.org/10.17632/v4w54r7snd.1 1 d04c4181-b321-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35562 RAZ_Megia-Palma_Rodrigo_2023.zip RAZ_Megia-Palma_Rodrigo_2023.zip 1 8CC64CE19C83021C6A132D84408570AE fb735b99a20660a49722c5fdec0b87f14ae8a46383e1aa8cbb6f2680bd538a17 f58abe6c-b321-11f0-9bb7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=35564 Nacionalni inštitut za biologijo Lizard host abundances and climatic factors explain phylogenetic diversity and prevalence of blood parasites on an oceanic island 0 0 0
