Ecology and Evolution, Volume 15, Issue 6, June 2025.This study evaluates the relative importance of Submersed Aquatic Vegetation (SAV) and filamentous mats in shaping epifaunal invertebrate communities in the central Baltic Sea. Our results showed that diversity, vertical structure, and biomass of SAV were all positively associated with higher total epifaunal abundance and greater abundance of ...

Testing for polytomies in phylogenetic species trees using quartet frequencies
, 2018 Phylogenetic species trees typically represent the speciation history as a bifurcating tree. Speciation events that simultaneously create more than two descendants, thereby creating polytomies in the phylogeny, are possible.

Cladistics, Volume 41, Issue 3, Page 283-303, June 2025.Abstract Using a new character matrix composed of revised matrices of previous analyses and new morphological findings, the phylogeny of Malacostraca (Pancrustacea) is analysed anew with 207 characters for 35 terminal taxa across all recognized orders. Particular emphasis was placed on methodological versatility, including different degrees of implied ...
