Resolving taxa in a challenging orchid species complex using evidence from phylogenetics, morphometrics and floral scent chemistry

TAXON, Volume 74, Issue 4, Page 787-804, August 2025.
Abstract Species can be difficult to circumscribe using morphology alone, and additional data can thus be useful for resolving challenging species complexes. Here we provide a case study of a South African orchid species complex which we resolved by analysing morphology, floral scent chemistry and molecular data.

Dynamics of Phytoplankton Communities and Their Characteristics of Realized Niches in a Drinking Reservoir

Ecology and Evolution, Volume 15, Issue 4, April 2025.
The realized niches in water temperature, pH, DO, and nutrient concentrations contribute to explaining the distribution patterns of the phytoplankton community in a drinking water reservoir. Realized niches contribute to understanding phytoplankton dynamics, offering valuable insights for the scientific management and prevention of phytoplankton blooms

Novel phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon Gothan reveals close affinity with extant Podocarpaceae (Coniferales)

Journal of Systematics and Evolution, Volume 63, Issue 2, Page 469-478, March 2025.
We perform a phylogenetic analysis of the Mesozoic common gymnosperm Xenoxylon to understand the systematic relationship with extant conifers. Data come from four nucleotide regions (trnL‐F, trnK‐matK, rbcL, psbA‐trnH), xylological characters, and biomolecular composition of five extant conifer families and extinct Xenoxylon. Using maximum parsimony in
