the main purpose of this survey was to identify and analyze of impacts of watershed plans implement in rural areas of zanjan province. the kind of research method of the study was descriptive-correlation research. the statistical population of the study consisted of all the heads of household in khomarak village (n= 170). according to morgan& krejcie table, 115 persons of them were selected by ...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
The distribution of culturable hyperthermophiles was studied in relation to environmental conditions in the Kubiki oil reservoir in Japan, where the temperature was between 50 and 58 degrees C. Dominant hyperthermophilic cocci and rods were isolated and shown to belong to the genera Thermococcus and Thermotoga, respectively, by 16S rDNA analyses. Using the most-probable-number method, we found ...
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...
The hydrogeochemical characteristics of the significant subterranean water body between “Cecina River and San Vincenzo” (Italy) was evaluated using multivariate statistical analysis methods, like principal component self-organizing maps (SOMs), with objective to study spatiotemporal relationships aquifer. dataset used consisted chemical composition groundwater samples collected 2010 2018 at 16 ...
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...
