Temporal variations in fatty acid composition of deep-sea holothurians: evidence of bentho-pelagic coupling
Fatty acid biomarkers were used to examine the diet of deep-sea holothurians. We collected 3 species from the Porcupine Seabight and Porcupine Abyssal Plain, NE Atlantic, between 800 and 4850 m in August 2001 (summer), March 2002 (pre-spring bloom), and October 2002 (autumn). Of these, 2 species, the abyssal Amperima rosea and the bathyal Bathyplotes natans, showed significant variations in fat...
متن کاملEcological and genetical survey on two deep-sea holothurians: Benthogone rosea and Benthodytes typica*
Ecological, biological and genetical features of 2 populations of deep-sea holothurlans have been studied. The 2 species concerned, Benthogone rosea Koehler and Benthodytes typica Theel belong to the strictly abyssal order Elasipoda. In the 2 collect~on areas they represent the dominant species of the megafauna. Trophic resources and other environmental characteristics are quite similar at the ...
متن کاملAsexual Reproduction in Holothurians
Aspects of asexual reproduction in holothurians are discussed. Holothurians are significant as fishery and aquaculture items and have high commercial value. The last review on holothurian asexual reproduction was published 18 years ago and included only 8 species. An analysis of the available literature shows that asexual reproduction has now been confirmed in 16 holothurian species. Five addit...
متن کاملVisceral regeneration in holothurians.
Holothurians, or sea cucumbers, exhibit two processes that have intrigued biologists for decades: autotomy and regeneration. Autotomy includes the loss of body parts by evisceration or fission, and regeneration is the extraordinary process by which the lost organs are replaced. In this article, we review the literature on evisceration, transection, and visceral regeneration in holothurians and ...
متن کاملAre thermal barriers "higher" in deep sea turtle nests?
Thermal tolerances are affected by the range of temperatures that species encounter in their habitat. Daniel Janzen hypothesized in his "Why mountain passes are higher in the tropics" that temperature gradients were effective barriers to animal movements where climatic uniformity was high. Sea turtles bury their eggs providing some thermal stability that varies with depth. We assessed the relat...
