Toxicity of tributyltin and triphenyltin to early life-stages of Paracentrotus lividus (Echinodermata: Echinoidea).
Sperm cell and embryo toxicity tests using the Mediterranean sea urchin Paracentrotus lividus were performed to assess the toxicity of tributyltin chloride, bis(tributyltin)oxide, triphenyltin acetate, and triphenyltin hydroxide. Toxicity values (mean effective concentration [EC50]) ranged from 2.97 to 18.5 microg/L for sperm cells and from 1.11 to 2.62 microg/L for embryos. For sperm cells, th...

In a mesocosm study, somatic and otolith growth of common dace (Leuciscus leuciscus) and bream (Abramis brama) differing in body size and body shape were studied in a wave and a no-wave control regime. A low-intensity wave treatment, causing hydrodynamic stress comparable to that resulting from distant ship traffic or moderate wind, caused significant changes in somatic growth and otolith daily...

متن کاملEffects of temperature and drought on early life stages in three species of butterflies: Mortality of early life stages as a key determinant of vulnerability to climate change?
Anthropogenic climate change poses substantial challenges to biodiversity conservation. Well-documented responses include phenological and range shifts, and declines in cold but increases in warm-adapted species. Thus, some species will suffer while others will benefit from ongoing change, although the biological features determining the prospects of a given species under climate change are lar...
