The geological, biological and geochemical features of a particular field of hydrothermal vents, discovered in the Panarea Volcanic Complex during a research survey carried out in 2015, are described for the first time. The site, located at 70-80 m depth off the South-western coast of the islet of Basiluzzo, was named Smoking Land for the presence of a large number of wide and high active chimn...

Copper is essential for healthy cellular functioning, but this heavy metal quickly becomes toxic when supply exceeds demand. Marine sediments receive widespread and increasing levels of copper contamination from antifouling paints owing to the 2008 global ban of organotin-based products. The toxicity of copper will increase in the coming years as seawater pH decreases and temperature increases....

The western Antarctic Peninsula is experiencing strong environmental changes as a consequence of ongoing regional warming. Glaciers in the area are retreating rapidly and increased sediment-laden meltwater runoff threatens the benthic biodiversity at shallow depths. We identified three sites with a distinct glacier-retreat related history and different levels of glacial influence in the inner p...

ABSTRACT To determine the presence of emergent contaminants in aquatic environments and to evaluate responses dominant taxa benthic macrofauna, seven stations were sampled along three rivers that serve as public water suppliers sampling campaigns, Upper Iguassu Basin, Brazil. Concentrations ethinylestradiol, fenofibrate, ibuprofen triclosan detected sediment. correlate patterns distribution abu...

plantations may influence soil fauna directly or indirectly. this research was conducted in order to study the influence of species plantations on soil macrofauna. plantations of eight tree species including nitrogen fixing trees and non-nitrogen fixing trees based on complete randomized block design with 3 replicates were established in 1372 in dez riverside. soil macrofauna were studied rando...

The Deepwater Horizon (DWH) accident in the northern Gulf of Mexico occurred on April 20, 2010 at a water depth of 1525 meters, and a deep-sea plume was detected within one month. Oil contacted and persisted in parts of the bottom of the deep-sea in the Gulf of Mexico. As part of the response to the accident, monitoring cruises were deployed in fall 2010 to measure potential impacts on the two ...

Deep-sea ecosystems represent the largest biome of the global biosphere, but knowledge of their biodiversity is still scant. The Mediterranean basin has been proposed as a hot spot of terrestrial and coastal marine biodiversity but has been supposed to be impoverished of deep-sea species richness. We summarized all available information on benthic biodiversity (Prokaryotes, Foraminifera, Meiofa...
