The first catalogue of the Romanian Cholevinae (excluding Leptodirini) is presented, based on revised and new records. The overall distribution and distribution in Romania are documented for every species, with particular reference to subterranean environment (caves and subterranean superficial environment). Epigeal and hypogeal records are listed separately. Thirty two of forty nine species gr...
Subterranean mammals spend their lives in dark, unventilated environments that are rich in carbon dioxide and ammonia and low in oxygen. Many of these animals are also long-lived and exhibit reduced aging-associated diseases, such as neurodegenerative disorders and cancer. We sequenced the genome of the Damaraland mole rat (DMR, Fukomys damarensis) and improved the genome assembly of the naked ...
INTRODUCTION There are two time frames in considering terrestrial subterranean ecology, the classical period of 1832−1980 dealing with caves, and the modern period after the 1980s when a wide range of other subterranean habitats were also considered. After Schmidt (1832) published the first scientific description of an invertebrate well adapted for living in hypogean habitats, the beetle Leptod...
Two new species of the genus Cylindroiulus Verhoeff, 1894, C. julesvernei and C. oromii, are described from the subterranean ecosystem of Madeira Island, Portugal. Species are illustrated with photographs and diagrammatic drawings. The new species belong to the Cylindroiulus madeirae-group, an insular species swarm distributed in the archipelagos of Madeira and the Canary Islands. We discuss th...
This study was conducted to identify lines of subterranean clover (Trifolium spp.) with resistance to Meloidogyne arenaria (Neal, 1989) Chitwood, 1949, race 1; M. incognita (Kofoid and White, 1919) Chitwood, 1949, race 3; and M. javanica (Treub, 1885) Chitwood, 1949. A collection of 134 subterranean clover lines was evaluated and all had intermediate to high susceptibility. Root galling was neg...
Hydrostatic balances between fresh and saline groundwater and saline surface water control the physical and chemical framework of subterranean estuaries, but they are responsive to high frequency (waves and tides), low frequency (seasonal recharge patterns), and episodic (storm) events. In this study, we document a salinity and pressure perturbation to the subterranean estuary in east-central F...
The need for reliable maps of subterranean spaces too hazardous for humans to occupy has motivated the development of robotic mapping tools. For such systems to be fully autonomous, they must be able to deal with all varieties of subterranean environments, including those containing loops. This paper presents an approach for an autonomous mobile robot to determine if the area currently being ex...
The cave barb habitat is located in a Karst formation along the Sezar River. The springs on the walls of the Sezar River valley may provide a means for fish in surface waters to penetrate into the underground waters. These observations propose the probability for a migratory relationship between Garra gymnothorax in the Sezar River and the cave barbs (Garra typhlops and Garra lorestanensis). In...
VASILEVA, V., E. VASILEV and R. TZONEV, 2016. Subterranean clover (Trifolium subterraneum L.) as a promising forage species in Bulgaria. Bulg. J. Agric. Sci., 22: 222–227 The paper presents an overview of the possibility to use the subterranean clover (Trifolium subterraneum L.) (an annual leguminous self-seeding species, widespread component in the pastures of the temperate areas of Central an...
Spatial learning and memory is an important skill for the survival and fitness and may vary between the sexes depending on differences in space use. This is particularly true for animals that explore the subterranean niche as it is associated with high travelling costs. In subterranean rodents the complexity of burrow systems varies with differing degrees of sociality possibly posing stronger s...
