Microsoroideae is the third largest of the six subfamilies of Polypodiaceae, containing over 180 species. These ferns are widely distributed in the tropical and subtropical regions of the Old World and Oceania. We documented the spore ornamentation and integrated these data into the latest phylogenetic hypotheses, including a sampling of 100 taxa representing each of 17 major lineages of microsoroid ferns. This enabled us to reconstruct the ancestral states of the spore morphology. The results show verrucate ornamentation as an ancestral state for Goniophlebieae and Lecanoptereae, globular for Microsoreae, and rugulate surface for Lepisoreae. In addition, spore ornamentation can be used to distinguish certain clades of the microsoroid ferns. Among all five tribes, Lecanoptereae show most diversity in spore surface ornamentation.

is one of the most widely cultivated ornamental fern species worldwide and a valuable component of the biodiversity of pantropical forests. In addition to its photosynthetic function, the sporotrophophyll leaves of this species periodically develop a large, clearly demarcated sporangium at the leaf tips, enabling physiological and biochemical measurements both in the active sporulation part and in the non-sporulating leaf area. The aim of this study was to assess anatomical changes, determine thermal effects and the content of selected phytohormones, and analyze the spatial distribution of pigments in the sporophilic and trophophylic part of the same leaf during spore formation.

The additive is already authorised for use in feed and water for drinking for the above-mentioned species. With this application, the company requested the modification of the current authorisations as regards the simultaneous use of the additive with the coccidiostats amprolium and narasin+nicarbazin.

Climate-driven variation in traits is crucial for predicting ecological responses to environmental change, yet global patterns and drivers of microbial trait variation remain poorly understood. Using global datasets of arbuscular mycorrhizal (AM) fungal observations linked to spore morphological traits, we show that climate shapes spore trait variation and functional diversity. Larger spore volumes were more prevalent in warm, wet climates but were associated with smaller species range sizes, suggesting a trade-off between persistence and dispersal potential.
