1. Leaf size and shape show contrasting relationships with evolutionary lineages in Daphne blagayana FreyerRobert Brus, Živa Fišer, Dalibor Ballian, Kristjan Jarni, 2026, izvirni znanstveni članek Opis: Phenotypic variation does not always correspond closely to genetic structure within species, particularly for morphological traits that are also influenced by environmental conditions. We examined whether leaf morphology in Daphne blagayana reflects previously identified phylogeographic structures and whether size- and shape-related traits differ in the hierarchical distribution of variation. Leaf morphometric analyses were performed on 3439 leaves collected from 596 shrubs in 21 populations covering the entire distribution range of the species. Ten leaf morphological traits were analysed using nested mixed-effects models, principal component analysis (PCA), MANOVA, Mantel tests and additional conservative mixed-effects models accounting for population-level structure. Leaf size-related traits showed stronger population-level differentiation and clearer geographic structuring, whereas shape-related traits exhibited higher within-shrub variation and weaker correspondence with phylogeographic structure. PCA and MANOVA revealed significant morphological differentiation among the three previously defined evolutionarily significant units (ESUs), although overlap among groups remained considerable. When population-level structure was taken into account, ESU effects were reduced but remained detectable for leaf length and selected shape-related traits. The northwestern ESU was characterized by larger and broader leaves, while differences between the central–southeastern and central ESUs were associated mainly with leaf shape traits. Mantel analysis revealed a weak but significant correlation between geographic and morphological distances among populations, indicating that geographic distance contributes to, but does not fully explain, morphological differentiation. The results show that leaf morphology in D. blagayana is associated with the previously identified phylogeographic structure of the species and that size- and shape-related traits differ markedly in their degree of geographic differentiation and hierarchical variation. However, because phylogeographic and geographic structure are spatially confounded in the present dataset, their individual effects on leaf morphology cannot be statistically separated. The study also highlights the importance of hierarchical sampling, appropriate statistical analyses, and cautious interpretation of genotype–phenotype correspondence in observational studies of intraspecific morphological variation.

2. Population genomics and the environmental drivers of population structure in a cosmopolitan marine predator, Tursiops truncatusDaniel M. Moore, André E. Moura, Ada Natoli, Elena Papale, Mónica A. Silva, Tilen Genov, Stefania Gaspari, Giuseppa Buscaino, Per Berggren, A. Rus Hoelzel, 2025, izvirni znanstveni članek Opis: The marine environment comprises vast regions without physical barriers to movement, making the understanding of population isolation and the evolution of diversity challenging. This is especially the case for highly mobile marine species. Here we investigate populations of the common bottlenose dolphin (Tursiops truncatus) across the Mediterranean Sea and adjacent North Atlantic using high-resolution genomic markers (RADseq) and stable isotope analyses to better understand the evolution of population structure in this system. High-resolution genomic data and broad geographic sampling revealed patterns of structure not previously identified, and integration with stable isotope data suggests that prey choice varies across this region. Unexpected patterns included genetic and isotopic similarity between the North Atlantic and the region around Sicily (but not including the medially located Gulf of Cádiz and surrounding regions). The regional habitat within and beyond the Mediterranean Sea is structured with ocean frontal systems including thermal and halocline transitions, several of which show alignment with genetic transitions within our data. Our data help to distinguish among possible drivers of population differentiation for a marine predator that has the potential for long-distance dispersion. 1 Introduction
