Fichas del conjunto (26)
- 1Major constituents of the Endocrine systemfemale ovaries, male testes, and the adrenal, thyroid, and pituitary glands
- 2sex steroidsandrogens (masculinizing) and estrogens (feminizing)
- 3estrogen resembling contaminantsPCBs and Bisphenol-A; cause estrogen like response/block natural estrogen
- 4Effects of Metals on Reproduction of FishDeleterious effects on reproductive gland growth, hormone concentration, sex expression, oogenesis + lipid content in ooplasm, fertilization success, and sperm motility
- 5Effects of Metals on Other TaxaPolychaetes + corals: Change in #no of eggs fertilized → toxicity to sperm and eggs
Echinoderms: no effects on sperm motility - 6Effects of Metals on CrustaceansDeleterious effects on reproductive glands, egg production and yolk content, hatching rates, maturation, growth, and molting
- 7Effects of Metals on MollusksDeleterious effects on fertility (imposex + sterilization), levels of sex free/esterified hormones, gamete maturation/expression, GSI, sexual maturation, and sperm motility
- 8Effects of Organics on Crustaceansdeleterious effects on gonadal development, hatching success, offspring mortality, development, and mating success
- 9Effects of Organics on Fishdeleterious effects on hormone levels, gonad development/growth, sperm count, egg/oocyte development, migratory/reproductive behavior, offspring survival, hatching rate/fecundity, and offspring development
- 10Effects of Organics on Mollusksdeleterious effects on gonad development/function, gamete development/maturation, gamete production, and offspring development
- 11Effects of Organics on Other Taxadeleterious effects on reproductive success, sex hormone levels, thyroid steroids, larvae release, fertilization, and offspring development/survival
- 12Effects of Climate Change on Fishhigher susceptibility to other pollutants, alteration in reproductive investment/habits
- 13Effects of Climate Change/Acidification on Crustaceanslittle deleterious effect (some hormesis), but at higher levels -> delayed hatching, reduced hatching success, and decreased offspring development/growth
- 14Effects of Acidification on Other TaxaCorals - reduced sperm count + motility
Echinoderms - no effects - 15Effects of hypoxia on fishreduced gonad growth
- 16Effects of Hypoxia on Crustaceansdeleterious effects on offspring survival, fertility; resistant species in estuaries -> only slower brood production
- 17Effects of CECs on Fishdeleterious effects on sex hormone production, fertilization, gonad development, and spawning success
- 18CuO vs CuCl2 effects on Mollusk reproductionnano-CuO had more deleterious effects on reproduction than CuCl2
- 19Effects of Polluted Sites on Fishdeleterious effects on gonadal development, hormone levels, reproductive behavior, egg production/development, fertilization + fecundity, offspring survival, and sexual maturation
- 20Effects of Polluted Sites on Crustaceansdeleterious effects on sex expression/hormone levels, egg development/survival, body size, and offspring production
- 21Effects of Polluted Sites on Mollusksdeleterious effects on spawning rate/period, gametogenesis, oocyte resorption, sex expression, fertilization, offspring survival, and populations of reproductive individuals
- 22Effects of polluted sites on Other taxaCorals: though hormone levels were altered by steroid pollution, no effects on reproductive success were observed
- 23Overall Effects on FishDeleterious effects on gonad development/growth, hormone concentration, sex expression, oogenesis + lipid content in ooplasm, fertilization success, sperm count and motility , migratory/reproductive behavior, offspring survival, hatching rate/fecundity, spawning success, susceptibility to other pollutants, and offspring development
- 24Overall Effects on CrustaceansDeleterious effects on gonadal development/growth, sex expression, hormone levels, fertility, egg production and yolk content, egg survival, hatching rates/success, offspring mortality/development, body size, sexual maturation, and mating success
- 25Overall Effects on MollusksDeleterious effects on fertility (imposex + sterilization), sex expression, levels of free/esterified sex hormones, gamete development/maturation/expression, oocyte resorption, GSI, sexual maturation, sperm motility, fertilization, gonad development/function, spawning rate/period, offspring development/survival, and populations of reproductive individuals
- 26Overall Effects on Other Taxapolychaetes: Change in #no of eggs fertilized (toxicity to sperm and eggs);
corals: Change in #no of eggs fertilized (toxicity to sperm and eggs), fewer breeding colony populations, lower ovary count, premature ejection of larvae, abnormal larval behavior, reduced growth, reduced gonad size, decreased sperm count/motility,
Mammals: premature birth, decreased reproductive success, hormone levels,
