Comparative Systematics of Subterranean Amphipod Crustaceans (Hadzioidea)
… species of <em>Hadzia</em> are described from subterranean waters in the Philippines, Palau and Guam. <em>Liagoceradocus </em>is synonymized with <em>Hadzia</em>and an updated diagnosis for the latter is provided.</p> <p>In the family Melitidae three new species of <em>Tegano</em> are …

Phylogenetics and biogeography of Australian subterranean Parabathynellidae.
The putatively ancient subterranean crustacean family Parabathynellidae has been poorly studied, in part because of the problem of obtaining material from difficult to access subterranean habitats in which they live. Further, the systematics of the group has been complicated by their generally …

Encapsulation of particles using brittle coatings for subterranean applications
The production of a brittle and moisture-resistant coating for particles, which reduce or "break" the viscosity of fracturing fluids, was explored.;The viscosity-reducer was ammonium persulfate. Polyurethane and acrylate coatings were investigated. The coated particles were assessed for dissolution …

Research in Biological Control of the Formosan Subterranean Termite
The Formosan subterranean termite, Coptotermes formosanus Shiraki, is a worldwide distributed pest of wooden structures and living plants that causes huge economic losses. Compared to chemical pesticides, biological control may provide a more environmentally friendly and persistent method for the …

Environmental Influences on Subterranean Termite Foraging Behavior and Bait Acceptance
… were significantly more likely to discover subterranean baits connected by physical guidelines than freestanding baits under both laboratory and field conditions. In the laboratory, subterranean termites built significantly longer tunnels adjacent to cellulosic guidelines than plastic …

BETWEEN LIGHT AND DARKNESS: THE ROUND-TRIP OF SURFACE AND SUBTERRANEAN ANIMALS
Caves are extreme environments, this definition is mostly due to the absence of sunlight that limits the abundance of trophic resources in this environment. The animals that live there, in order to exploit of this ecosystem, must show particular adaptations such as an extremely reduced metabolism, …

Comparative Systematics of Subterranean Amphipod Crustaceans in the Families Crangonyctidae and Bogidiellidae
… systematics of two different taxonomic groups of subterranean amphipods (Crustacea). Therefore, rather than being a single project, this study is divided into several sub-projects. Altogether, the chapters for the sub-projects are composed of five publications. An introductory chapter and a …

Subterranean governance: The political work of artisanal miners in the northern Peruvian Andes
… embedded in local power structures by forming a subterranean state, which refers to actors and institutions that, while publicly operating under a state-like guise, critically depend on revenues from informal mining to fulfill their functions. Third, it reveals the constitution of frontier …

Groundwater management using a GIS case study : Uitenhage Subterranean Government Water Control Area
The area around Uitenhage in the Eastern Cape forms the centre of one of the biggest artesian groundwater basins in South Africa. The Table Mountain Group quartzitic sandstones are overlain by a thickness of postPalaeozoic sediments giving rise to artesian groundwater. The most wellknown of this …

Hexaflumuron Efficiency and Impact on Subterranean Termite (Reticulitermes spp.) (Isoptera: Rhinotermitidae) Gut Protozoa
The effect of competing food sources on termite consumption of hexaflumuron bait and subsequent mortality was examined. Also, the effect of hexaflumuron on the termite gut fauna was evaluated to determine if hexaflumuron could kill termites via a secondary mode of action. Hexaflumuron consumption …

Assessing Subterranean Arthropod Diversity through COI Barcoding in Two Ecoregions of Southwestern Virginia, USA
Subterranean arthropod communities are important components of North American ecosystems, contributing numerous ecosystem services and essential food-web functions. Despite this, fundamental information about species diversity in these communities remains unknown, and their taxonomic composition …

Distribution and behavior of trace metals in the subterranean estuary of an Arctic coastal lagoon
Subterranean estuaries (STEs) can be an important location for biogeochemical reactions that may alter concentrations of chemical constituents of groundwater. With warming in the Arctic and the subsequent permafrost thaw, the relative importance of submarine groundwater discharge (SGD) to ocean …

Physical and chemical controls on carbonate precipitation in surficial hot springs and subterranean cold springs
Rimmed-pool deposits in surficial hot springs at Yellowstone National Park, WY, and cold springs in Fogelpole Cave, IL, are compared to determine physical and chemical parameters controls on carbonate precipitation. Macroscale (> 0.5mm) morphology and depositional patterns of carbonate …
