In this paper, we report the microspore morphology of 18 species in genus Selaginella P.Beauv. of family Selaginellaceae Willk. from China observed using scanning electron microscopy. Among these species, the morphological characteristics of 17 species have not been reported previously. The results show that the surface ornamentation of microspores...

Building from a continuous-time host-parasitoid model introduced by Murdoch et al. (Am Nat 129:263-282, 1987), we study the dynamics of a 2 host-parasitoid model assuming, for the sake of simplicity, that larval stages have a fixed duration. If each host is subjected to density-dependent mortality in its larval stage, we obtain explicit conditions...
Xerocomus silwoodensis is reported for the first time in Ukraine. For the specimens collected in Khmelnytskyi Region, descriptions of the macro- and microstructures and results of the ITS barcoding are provided. The authors also discuss differences between X. silwoodensis and related species of Xerocomus s. str. (X. ferrugineus, X. subtomentosus, a...
A series solution is constructed in terms of Airy functions for a nonlinear two-point boundary-value problem arising in an established model of steady electrodiffusion in one dimension, for two ionic species carrying equal and opposite charges. The solution includes a formal determination of the associated electric field, which is known to satisfy...
A new species of bent-toed gecko, Cyrtodactylus adleri, is described, based on seven examples from the island of Great Nicobar, India. Although reported as conspecific with C. rubidus, it can be differentiated from the Andamanese species in possessing dark spots (vs. dark bands) on the dorsum; 48-50 imbricate (vs. 38-42 juxtaposed) midventrals; six...

Powdery mildew is a prevalent fungal disease that affects various Veronica spp. (Plantaginaceae), caused by species in the genera Podosphaera and Golovinomyces (Erysiphales). There have been recent taxonomic changes in these groups and ongoing disease occurrence on a range of Veronica species previously unrecognized as hosts; however, the pathogen found in Korea remains unidentified. This study aimed to identify the causative agent of powdery mildew on Veronica spp. in Korea through molecular phylogenetic analysis of internal transcribed spacer (ITS) and large subunit (LSU) sequences of rDNA and morphological examination. Our study identified Golovinomyces bolayi as the sole pathogen affecting all nine Veronica species in Korea and confirmed that G. cichoracearum s. str., which was previously identified as the pathogen, was not the causal agent. These results expand the known host range of G. bolayi, including the addition of five Veronica species in Korea: V. hederifolia, V. kiusiana var. glabrifolia, V. longifolia, V. polita, and V. serpyllifolia. Notably, V. kiusiana has been added as a new global host of powdery mildew. These findings substantially enhance our understanding of the taxonomy of powdery mildew pathogens on Veronica species and provide valuable insights into their evolutionary host expansion.
