The orientation and position of hard substrata used to test ecological hypotheses about sessile marine plants and animals have often been based on logistical convenience. Much of our understanding of the ecology of epibiota is based on artificial habitats (particularly the undersides of floating pontoons), despite epibiotic organisms being an important and conspicuous component of natural hard ...

The paper deals with the standing stock of macrobenthic infauna and associated environmental factors influencing the benthic community in the shelf region of the northwest Indian coast. The data were collected onboard FORV Sagar Sampada during the winter monsoon (January-February, 2003) to understand the community structure and the factors influencing the benthic distribution. The environmental...

Polychaetes inhabiting deep-sea soft bottoms from the southeastern Gulf of California were collected during four oceanographic cruises during 2000 and 2001. Sampling of benthic organisms was performed with a benthic sledge to collect epifauna and a Karling dredge for epifauna and infauna, in a depth range from 732 to 2 250 m. A list of the polychaetes that were collected and their distribution ...

Multispecies, or mass, spawning of different invertebrate species is well known for coral reef systems; however, incidences involving polychaetes are poorly documented. In this study we report on mass swarming, prior to spawning, of Nereididae at Ambon Island, Maluku, on three occasions: in 1866, inferred from an historical sample deposited in Naturalis, Leiden, and in March, 2009 and 2014, bas...

The continuous increase of CO 2 emissions in the atmosphere due to anthropogenic activities is one most important factors that contribute Climate Change and generates phenomenon known as Ocean Acidification (OA). Research conducted at vents Castello Aragonese (Ischia, Italy), which represents a natural laboratory for study OA, demonstrated some organisms, such polychaetes, thrive under acidifie...

conclusion this study demonstrated that repeating the tfna procedure in pulmonary lesions improves the diagnostic yield without an increase in the rate of pneumothorax. objectives we aimed to investigate whether repeating ct-guided transthoracic fine needle aspiration (tfna) increases diagnostic yield and complication rate. patients and methods patients underwent tfna and the final diagnoses ac...

background: the aim of this study was to estimate the frequency and rate of the first 50 common types of invasive procedures in iran. methods: data about the number of all invasive procedures and each type of procedure that were conducted in iran in 2010 were collected using the main insurance organizations database. these numbers were sorted in an excel database, and the first 50 invasive proc...
