1. Notes on Abutilon (Malvaceae) in the Mediterranean and MacaronesiaFilip Verloove, 2025, ni določena Povzetek: Recent field- and herbarium studies in the genus Abutilon in the Mediterranean and Macaronesia yielded some noteworthy results. The invasive South American weed A. grandifolium is reported for the first time from Algeria. A recent claim of A. grandiflorum from the Canary Islands is erroneous and referable to A. grandifolium. Historical records of the South African A. sonneratianum from Madeira are also discussed. This species is included in the list of invasive species in Portugal. However, it is shown that the invasive species in Portugal (Madeira) is A. grandifolium, not A. sonneratianum.

2. Lizard host abundances and climatic factors explain phylogenetic diversity and prevalence of blood parasites on an oceanic islandRodrigo Megía-Palma, Gemma Palomar, Javier Martínez, Bernardo Antunes, Katarzyna Dudek, Anamarija Žagar, Nina Guerra Serén, Miguel A. Carretero, Wiesław Babik, Santiago Merino, 2024, izvirni znanstveni članek Povzetek: 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. 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. 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 haplotypes 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. We conclude that 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.
