The Macaronesia bioregion is experiencing an increase in the frequency, intensity and magnitude of fires. However, impact that this new fire regime may have on endemic fauna flora many islands, such as those Canary archipelago, unknown. In study we analyzed short-term response Gallot’s lizard, Gallotia galloti, to a occurred northwestern part La Palma summer 2023. We carried out 187 linear transects burned unburned pine forest mountain scrub plots June, July, September 2024, hence, almost...
Studying the causes of parasite geographic distribution is relevant to understand ecological and evolutionary processes that affect host populations as well for species conservation. Temperature one most important environmental variables affecting distribution, raising temperatures positively development, reproduction, rate transmission both endo- ectoparasites. In this context, it generally accepted that, in mountains, abundance decreases with elevation. However, empirical evidence on topic...
The genus Karyolysus was originally proposed to accommodate blood parasites of lacertid lizards in Western Europe. However, recent phylogenetic analyses suggested an inconclusive taxonomic position these the order Adeleorina based on available genetic information. Inconsistencies between molecular phylogeny, morphology, and/or life cycles can reflect lack enough information target group. We therefore surveyed 28 localities and collected samples from 828 23 species including lacertids,...
Host abundance might favour the maintenance of a high phylogenetic diversity some parasites via rapid transmission rates. Blood insular lizards represent good model to test this hypothesis because these can be particularly prevalent in islands and host highly abundant. We applied deep amplicon sequencing analysed environmental predictors blood parasite prevalence endemic lizard Gallotia galloti across 24 localities on Tenerife, an island Canary archipelago that has experienced increasing...
SUMMARY In the present study we detected Schellackia haemoparasites infecting blood cells of Lacerta schreiberi and Podarcis hispanica , two species lacertid lizards from central Spain. The parasite morphometry, presence a refractile body, type infected cells, kind host species, lack oocysts in fecal samples clearly indicated these parasites belong to genus . Until now, this have never been genetically characterized its taxonomic position under Lankesterellidae family is based on exogenous...
The current taxonomy on the haemococcidia establishes that two genera of protozoan parasites integrate family Lankesterellidae are L ankesterella and S chellackia . However, phylogeny these genera, as well other coccidia, remains unresolved. In this sense, use type described species is essential for resolution systematic conflicts. study, we molecularly characterize genus , is, bolivari from Europe also a same Asia. At time, contribute with molecular characterization another All put together...
The honesty of structural-based ornaments is controversial. Sexual selection theory predicts that the a sexual signal relies on its cost production or maintenance. Therefore, environmental factors with negative impact individuals could generate high costs and affect expression these signals. In this sense, parasites are main for their hosts. To probe effect coloration lacertid species Lacerta schreiberi, we have experimentally removed ticks from group male Iberian green lizards using an...
Abstract Ontogeny is expected to be a determinant factor affecting production of colour patches in lizards, while immune challenges or sudden weight loss may impair the maintenance pigment-based coloration within breeding season. We translocated males lizard Psammodromus algirus between two sampling plots that differed distance road, vegetation structure, and predator abundance. analysed variation spectral reflectance their same following year. The change first season was explained by...
In the past decades, nocturnal temperatures have been playing a disproportionate role in global warming of planet. Yet, they remain neglected factor studies assessing impact on natural populations. Here, we question whether an intense augmentation is beneficial or deleterious to ectotherms. Physiological performance influenced by thermal conditions ectotherms and increase temperature only 2°C sufficient induce metabolic expenditure. Warmer nights may expand ectotherms' species niche open new...
Abstract Aim Physiological and metabolic performance are key mediators of the functional response species to environmental change. Few environments offer such a multifaceted array stressors as high‐altitude habitats, which differ markedly in temperature, water availability, UV radiation oxygen pressure compared low‐altitude habitats. Species that inhabit large altitudinal gradients thus excellent models study how organisms respond variation. Location Tenerife island, Canary Islands...
Abstract Mitigation-driven translocations represent an increasingly common management solution to reduce animal mortality and habitat loss caused by human development. Although they currently outnumber other translocation types, there is a lack of scientific approaches evaluate the outcome this tool. We designed experimental with two groups translocated males control small (6-14 g) lizard (totaling 120 individuals). Our results suggest that individuals covered longer distances (53 vs. 18 m)...
Abstract
Abstract Several studies of lizards have made an erroneous interpretation negative relationships between spectral brightness and parasite load, thus provided misleading support for the Hamilton–Zuk hypothesis (HZH). The HZH predicts that infected hosts will produce poorer sexual ornamentation than uninfected individuals as a result energetic trade-offs immune signalling functions. To test whether there is relationship pigment content in skin lizards, we used spectrophotometry to quantify...
Better understanding how organisms respond to their abiotic environment, especially at the biochemical level, is critical in predicting population trajectories under climate change. In this study, we measured constitutive stress biomarkers and protein post-translational modifications associated with oxidative Gallotia galloti , an insular lizard species inhabiting highly heterogeneous environments on Tenerife. Tenerife a small volcanic island relatively isolated archipelago off West coast of...
Reptiles are the animals with most described coccidian species among all vertebrates. However, co‐evolutionary relationships in this host–parasite system have been scarcely studied. Paperna & Landsberg ( South African Journal of Zoology , 24, 1989, 345) proposed independent evolutionary origin Eimeria ‐like isolated from reptiles based on morphological and developmental characteristics their oocysts. Accordingly, they suggested reclassification these parasites two new genera,...
Species of Schellackia Reichenow, 1919 have been described from the blood reptiles distributed worldwide. Recently, spp. detected in European and Asian lizards molecularly characterised. However, parasites American lizard hosts remain uncharacterised. Thus, phylogenetic affinities between Old New World parasite species are unknown. In present study, we characterised morphologically hemococcidian (sporozoites) that infect three North America two South America. total, generated 12 new 18S rRNA...
