The BEAC, an epigenetic clock for birds

Mikaela Hukkanen, Simon Jarman, Alyssa Maree Budd, Flávia A. N. Fernandes et autres

Abstract Epigenetic clocks are powerful tools for estimating both chronological and biological age, enabling the integration of age information into population monitoring, demographic modelling, and research on the ecophysiology and evolution of ageing. Most epigenetic clocks so far have been developed for …

Contrasting patterns of population structure and historical dynamics between two octopus species, Eledone moschata (Lamarck, 1798) and Eledone cirrhosa (Lamarck, 1798), in the Mediterranean basin

Masoud Nazarizadeh, Tijana Cvetković, Marie Drábková, Jan Štefka

Abstract Understanding the ecological and evolutionary history of marine organisms is critical for the sustainable management of marine resources. Accurate identification of biologically relevant management units, aligned with biological rather than political boundaries, is fundamental to preserving biodiversity, maintaining ecosystem function, and …

Does immunogenetic diversity warrant fewer parasites in European bluethroats?

Dragomir Damnjanović, Masoud Nazarizadeh, Václav Pavel, Bohumír Chutný et autres

Abstract The health and fitness of vertebrates are constantly challenged by environmental stresses that pose significant evolutionary pressures on immune genes. The bluethroat (Luscinia svecica) has been extensively studied for its haemosporidian parasites across Europe, showing high diversity and prevalence rate. The …

Contrasting patterns of population structure and historical dynamics between two octopus species, Eledone moschata (Lamarck, 1798) and E. cirrhosa (Lamarck, 1798), in the Mediterranean basin

Masoud Nazarizadeh, Tijana Cvetković, Marie Drábková, Jan Štefka

This dataset contains genome-wide SNP data (VCF files) and mitochondrial COI sequences used to investigate genetic diversity, population structure, and demographic history of two closely related octopus species, Eledone moschata and Eledone cirrhosa, across the Mediterranean Sea and adjacent Northeast Atlantic Ocean. …

Immunogenetic diversity and haemosporidian parasitization in European bluethroats (Luscinia svecica): do diverse genes warrant fewer parasites?

Dragomir Damnjanović, Masoud Nazarizadeh, Václav Pavel, Bohumír Chutný et autres

The health and fitness of vertebrates are constantly challenged by environmental stresses, which include exposure to diseases that pose significant evolutionary pressures on immune genes. The bluethroat (Luscinia svecica), has been extensively studied for its haemosporidian parasite diversity across Europe showing a …

Complete mitochondrial genome assembly and analysis of a Neotropical lineage of Ligula intestinalis reveals evolutionary and phylogenetic insights

Aarón Mondragón-Martínez, Rosa Martínez-Rojas, Inés Gárate, Jaime R. Sánchez-Venegas et autres

Ligula intestinalis (Cestoda: Diphyllobothriidea) is a cosmopolitan tapeworm parasite characterized by a complex life cycle that includes freshwater fish infection. Ligula disrupts host reproduction, and causes ecological imbalances. Despite its broad geographic distribution and ecological significance, molecular data for South American populations …

Amplicon sequencing reveals the cryptic diversity in the dicyemid parasites of coleoid cephalopods sampled from the Atlantic and Pacific Oceans

Tijana Cvetković, Masoud Nazarizadeh, Tereza Koudelková, Fedor V. Lishchenko et autres

Abstract Dicyemids (phylum Dicyemida), primarily found in the renal organs of coleoid cephalopods, are a unique group of morphologically simple parasites with global distribution. Here, we investigated the diversity and prevalence of dicyemid communities in a wide range of cephalopod hosts across …

Generalist vs. specialist strategy shapes microbiomes in blood feeding parasite Polyplax serrata

Damián Dedecius, Jakub Kolář, Jana Martinů, Jan Štefka et autres

Insects live in association with bacterial communities, collectively referred to as the microbiome. Microbiome composition varies widely across insect taxa and is shaped by multiple factors, including host phylogeny, environmental conditions, geographic distribution, and nutritional ecology. One hypothesis is that microbiome composition …

Host-Associated Genetic Differentiation in the Face of Ongoing Gene Flow: Ecological Speciation in a Pathogenic Parasite of Freshwater Fish

Masoud Nazarizadeh, Milena Nováková, Jakub Vlček, Jan Štefka

Adaptive evolution in response to varying environments, leading to population divergence, is among the most intriguing processes of speciation. However, the extent to which these adaptive processes effectively drive population divergence amidst ongoing gene flow remains controversial. Our study addresses this by …
