“…Blount et al (2002Blount et al ( , 2004 similarly found that female lesser black-backed gulls (Larus fuscus) deposit more carotenoids in egg yolk and raise more offspring when supplemented with dietary carotenoids (but see Bortolotti et al 2003 for the lack of an effect on reproductive output in red-legged patridges, Alectoris rufa). Certain fish (Torrissen and Christiansen 1995;Shahidi et al 1998), sea urchin (Tsushima et al 1997;George et al 2001), and mammal (Chew and Archer 1983;Brief and Chew 1985) species also gain reproductive benefits by consuming large amounts of dietary carotenoids. Female animals might also be expected to maximize fitness by biasing the sex ratio of their offspring, favoring the production of sons when breeding conditions are favorable and when variance in male reproductive success is higher than that of females (Trivers and Willard 1973).…”

In egg-laying animals, mothers can influence the development of their offspring via the suite of biochemicals they incorporate into the nourishing yolk (e.g. lipids, hormones). However, the long-lasting fitness consequences of this early nutritional environment have often proved elusive. Here, we show that the colorful carotenoid pigments that female zebra finches (Taeniopygia guttata) deposit into egg yolks influence embryonic and nestling survival, the sex ratio of fledged offspring, and the eventual ornamental coloration displayed by their offspring as adults. Mothers experimentally supplemented with dietary carotenoids prior to egg-laying incorporated more carotenoids into eggs, which, due to the antioxidant activity of carotenoids, rendered their embryos less susceptible to free-radical attack during development. These eggs were subsequently more likely to hatch, fledge offspring, produce more sons than daughters, and produce sons who exhibited more brightly colored carotenoid-based beak pigmentation. Provisioned mothers also acquired more colorful beaks, which directly predicted levels of carotenoids found in eggs, thus indicating that these pigments may function not only as physiological 'damage-protectants' in adults and offspring but also as morphological signals of maternal reproductive capabilities.

“…The cytotoxic acetylenic carotenoids diatoxanthin, and alloxanthin were present in the gonads of Australian and Japanese species of the echinoids Heliocidaris erythrogramma and H. tuberculata (380); in the sea urchin Pseudocentrotus depressus (381); in the sea urchin Peronella japonica (382); in seven species of sea urchins, belonging to the orders Cidaroida, Echinothurioida, Diadematoida, and Arbacioida, as well as pectenolone (308) and 4-keto-cynthiaxanthin (309) (383).…”

This review is a comprehensive survey of acetylenic lipids and their derivatives, obtained from living organisms, that have anticancer activity. Acetylenic metabolites belong to a class of molecules containing triple bond(s). They are found in plants, fungi, microorganisms, and marine invertebrates. Although acetylenes are common as components of terrestrial plants, fungi, and bacteria, it is only within the last 30 years that biologically active polyacetylenes having unusual structural features have been reported from plants, cyanobacteria, algae, invertebrates, and other sources. Naturally occurring aquatic acetylenes are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifouling, antifungal, pesticidal, phototoxic, HIV-inhibitory, and immunosuppressive properties. There is no doubt that they are of great interest, especially for the medicinal and/or pharmaceutical industries. This review presents structures and describes cytotoxic and anticancer activities only for more than 300 acetylenic lipids and their derivatives isolated from living organisms.

“…To obtain the highest dietary concentration of carotenoids it would be beneficial to feed on the freshest organic matter -as supported by the high chlorophyll a concentration found in some A. rosea gut content samples. Experiments on shallow water echinoderms have shown that the larvae of adults fed carotenoids were larger throughout development, developed faster and had higher survival rates (Tsushima et al, 1997;George et al, 2001;George & Lawrence, 2002). Assimilating a high carotenoid load into its ovaries may give A. rosea an additional reproductive advantage.…”

suggested by the interspecific differences in holothurian ovarian biochemistry. This may lead to large community changes as seen at the PAP, which can alter the reworking rates of sediment, probably affecting carbon burial. The study also demonstrated that using the presence of biomarkers in gut contents to infer feeding selectivity should be used with caution. Only biomarkers in gut contents that are not present in the tissues of the holothurians (e.g chlorophyll a) should be used to determine their feeding selectivity.
