There Is More to the Taxonomy of Schoenus apogon (Cyperaceae) Than Meets the Eye: An Unresolved Complex With Cytological DiversityNARA Subscribed
Schoenus apogon s . lat . is widely distributed in Australia, Japan and New Zealand. There has been limited cytological and molecular study of this species complex and putatively related species. Different chromosome numbers have been reported from New Zealand (2 n = 8) and Japan (2 n = 18), perhaps indicating taxonomic differences. We investigate the chromosome diversity and phylogenetic relationships in the S . apogon comple...
Impact of extreme rainstorm on the spatial distribution of population exposure in Haihe River basin in ChinaNARA Subscribed
Based on daily rainfall data from 252 national meteorological stations in the Haihe River Basin of China during 1961–2023, rainstorm events were divided, and four characteristic variables representing the hazard index of rainstorms were statistically analyzed, including total number of rainstorm days ( I day ), cumulative rainfall ( I pre ), average daily rainfall ( I 24pre ), and maximum duration days ( I dur ). Combined with...
The Kulanaokuaiki Tephra Unit 3 (900 C.E.) was a subplinian basaltic scoria eruption, the largest known to have occurred at Kīlauea’s summit. The initiation mechanism and cause(s) of this highly hazardous eruption remain poorly understood, particularly as this style of activity has not been observed in the modern period. We use olivine diffusion timescales from Fe-Mg and lithium zoning to assess magma storage timescales and ev...
