The organic-walled genera Resigella and Conicotheca (Protista, Foraminifera) at two Arctic deep-sea sites (North Pole and Barents Sea), including the description of a new species of Resigella

Abstract

We describe a new organic-walled foraminiferan species from the central Arctic Ocean (North Pole; 4,300 m water depth) and the Håkon Mosby Mud Volcano (HMMV) at the south-western

Nematode species distribution patterns at the Håkon Mosby Mud Volcano (Norwegian Sea)

“…(2006) studied benthic Foraminifera from the HMMV, focusing on the stable isotope chemistry of their calcareous shells, while Wollenburg & Mackensen (2009) described associations of hard‐shelled Foraminifera from different habitats inside and outside the mud volcano. Gooday et al. (2010) described a new organic‐walled foraminiferan species from the HMMV.…”

“…In addition, Mackensen et al (2006) studied benthic Foraminifera from the HMMV, focusing on the stable isotope chemistry of their calcareous shells, while Wollenburg & Mackensen (2009) described associations of hard-shelled Foraminifera from different habitats inside and outside the mud volcano. Gooday et al (2010) described a new organic-walled foraminiferan species from the HMMV. De performed a series of field and laboratory measurements in four different habitats (the centre of the mud volcano with plain sediments, white Beggiatoa mats, grey bacterial mats, and siboglinid fields) to determine process rates and responsible microorganisms, their distribution patterns, and their link to mass transfer phenomena.…”

Foraminifera of the Kuril–Kamchatka Trench area: The prospects of molecular study

“…These peculiar organicwalled forms are very common in the deep-sea samples, dwelling even at the greatest depths (Gooday et al, 2008b;Sabbatini et al, 2002;Todo et al, 2005). However, their origins remain enigmatic, as none of them has been sequenced so far (Gooday et al, 2008a(Gooday et al, , 2010. Their test morphology and the appearance of the cytoplasm strongly suggest their affinity to Foraminifera, but just as in case with komoki their pseudopodia have never been observed, and their unusual organic wall in combination with the tendency to develop test segments (in Nodellum) or even chambers (in Resigella) leaves open questions on the precise taxonomic placement.…”

Monothalamous soft-shelled foraminiferal image dataset from the Kveithola Trough (NW Barents Sea)

“…Species identification followed previous studies from the high latitude environments and in particular for the soft-shelled monothalamous foraminifera taxonomy we followed the scientific works conducted by [13] , [14] , [15] , [16] .…”
