Molecular Phylogeny Of Cave Dwelling Eremogryllodes Crickets (Orthoptera, Myrmecophilidae) Across Zagros Mountains And Southern Iran, Mohadeseh Sadat Tahami, Mina Hojat-Ansari, Anna Namyatova, Saber Sadeghi

International Journal of Speleology

Recently, several new species and subspecies from the genus Eremogryllodes Chopard, 1929 (Insecta: Orthoptera: Myrmecophilidae) inhabiting caves of Iran, have been described based on morphology. The high variation of genitalia structure along with high similarity of external morphology between populations hamper the precise species identification. Thus, molecular approaches are critical to determine the taxonomic positions of species/subspecies of this genus. Here we provide the molecular phylogeny, based on the 16S rRNA mitochondrial gene, of recently described species of Eremogryllodes along with some unidentified specimens from the same region. The results support the monophyly of the family Myrmecophilidae. The topology of …

Diversity Of Cultivable Bacteria Involved In The Formation Of Macroscopic Microbial Colonies (Cave Silver) On The Walls Of A Cave In Slovenia, Blagajana Herzog Velikonja, Rok Tkavc, Lejla Pašić

International Journal of Speleology

Karstic caves often support white, yellow, grey or pink microbial colonies that are termed ‘cave silver’ by speleologists. Using various sample pre-treatments and culture media, a wide variety of bacteria associated with these colonies were recovered from a cave in Slovenia, Pajsarjeva jama. Decreasing the inoculum size resulted in significant increases in viable counts, while pre-treatments had the opposite effect with the exception of microwave irradiation. While all growth media yielded viable counts, the maximal counts were observed on a low-nutrient TWA medium.

Based on the 16S rRNA gene sequence of OTU representatives, the majority of the 80 isolates examined …
