Field of study
We present the first ever observations of dwarf crocodiles (Osteolaemus tetraspis) selectively utilizing a cave ecosystem. We analysed crocodile diet to preliminarily assess the degree of ecological isolation of cave-dwelling crocodiles from their forest-dwelling conspecifics despite their physical proximity. We additionally conducted the first stu...
As an obsolete underground water supply system, the qanāt is particularly affected by the destruction and demolition taking place within the oases of Saudi Arabia. In a period of economic and demographic growth, the oasis of Dūmat al-Jandal (province of Jawf) is a good example of such an evolution. Qanāts have been replaced by everdeeper pumping sy...
An update is provided of current knowledge of the herpetofauna and batrachofauna recorded from caves in Gabon, western Equatorial Africa. No systematic field survey of reptiles and amphibians in Gabonese cave environments has yet been made, and data are available for only 19 (complexes of) caves. This compilation of published records and new observ...

Distribution map of occurence of bats roosts in the caves of Cameroon, as observed by the author during the 2009-2010-2011 speleological prospections. The order (Megachiroptera, Microchiroptera), based on visual assessment, is noted when available.
Description of the flooded cave Cueva de Macho in the Dominican Republic, the longest underwater cave to date in the country. Preliminary reporting of the abundant fossil bone deposits in the cave, rich in sloths, crocodiles, and millions of bat bones. Preliminary observations of the stygobitic life.
Photographs (annotated) of all 182 artifacts (iron currency knives, hoes, iron and copper bracelets, rings, kindu, gong) and 51 cranium bones visible on the ground during the initial visit of the Iroungou burial cave, Mouila area, Gabon, on september 23, 2018.
