Diatopic variation refers to the differences in language or dialect that occur across geographical regions. It encompasses variations in phonetics, vocabulary, and grammar that arise due to the influence of local culture, history, and social factors, leading to distinct linguistic features in different locations.

Key research themes

1. How can statistical and morphometric methods differentiate diatom species complexes in the presence of overlapping morphological traits?

This research theme focuses on distinguishing taxonomically challenging diatom taxa that form species complexes with overlapping morphological and ecological characteristics. It is critical for achieving accurate identification necessary for ecological monitoring, paleoenvironmental reconstructions, and biodiversity assessments. Researchers investigate the efficacy of morphometry-based classification alone and the integration of morphometric parameters with statistical and computational tools to improve species discrimination.

Key finding: This study tested whether morphometric parameters (valve length, width, stria density) alone, combined with unsupervised statistical classification algorithms, could resolve closely related Gomphonema species complexes.... Read more
Key finding: Using a large dataset of Gomphonema taxa and multiple computational classification methods (mixture analysis, k-means, discriminant analysis), the authors found poor discrimination of morphologically similar species based... Read more
Key finding: By analyzing multiple genera historically grouped and re-assigned based on valve symmetry and ultrastructural characters, this work showed that gross morphological traits like valve shape and symmetry evolved convergently in... Read more

2. What ecological and biogeographical processes shape diatom community assembly and species richness patterns on islands versus continents?

Understanding the assembly mechanisms driving diatom diversity on islands and continents is key to elucidating patterns of microbial biogeography and niche differentiation. This theme investigates how deterministic (environmental filtering, selection) and stochastic (dispersal limitation, drift) processes, along with area, isolation, climate, and local water chemistry, influence community composition and species richness. Island biogeography theory is tested on diatoms at global scales, with comparisons including functional guilds and taxon uniqueness.

Key finding: The study found significant distance-decay relationships (DDS) in diatom community similarity across six tropical reservoirs in Brazil. Similarity decreased with spatial distance and varied between phytoplankton and sediment... Read more
Key finding: This global-scale analysis revealed that species richness of stream benthic diatoms shows a significant positive species-area relationship (SAR) in continental equivalents but not on islands. Richness on islands was closely... Read more
Key finding: Using beta diversity null models and joint species distribution modeling across multiple islands and continents, the authors demonstrated that deterministic homogeneous selection dominates assembly processes within islands,... Read more

3. How can advanced geometric morphometric and mathematical frameworks improve analysis of biological symmetry and shape variation for diatoms and other organisms?

This theme addresses methodological innovations in quantifying biological symmetry beyond bilateral forms common in traditional morphometrics, extending to rotational, biradial, and complex symmetries frequently observed in diatom frustule morphology and colonial organisms. The development of group theory–based frameworks and geometric morphometric methods enables decomposition of shape variation into symmetric and asymmetric components, which is important for evolutionary biology, developmental instability analyses, and functional morphology studies.

Key finding: This paper generalizes the morphometric analysis of symmetry from bilateral forms to any type of symmetry (including biradial, rotational, and translational) through a mathematical framework based on symmetry groups. The... Read more
Key finding: The authors proposed the α-minimum convex polygon (α-MCP) method—traditionally used in ecological home range estimation—to quantify isotopic niches in bivariate stable isotope data of δ13C and δ15N. This approach allows... Read more
Key finding: The extension of Procrustes ANOVA to complex symmetric structures enables quantification of directional and fluctuating asymmetry for multiple symmetry types beyond bilateral, critical for disentangling developmental and... Read more
