“…Temperature and salinity are likely the most effective ecological drivers of C. intestinalis demographic trends (Dybern ; Vercaemer et al . ). In the present study, precipitation appears to play no role in shaping the biological parameters analysed at this juncture.…”

Ciona intestinalis sp. A (Tunicata, Ascidiacea) is a marine invertebrate with a widespread distribution and high invasive potential, yet little is known about its ecology. Here, the macrodynamics of demographic and reproductive trends were first determined using archive data covering 2002–2012. Species abundance in the central Tyrrhenian Sea (Campania, Italy ‐ NW Mediterranean) displayed Poisson distribution across 2002–2008, massive die‐off in 2009/2010 and population recovery in 2011/2012. We defined the seasonal ranges of sea surface temperature in which sampling size, animal size and reproductive status reached their highest values. In 2003/2004, self and non‐self fertilization appeared to follow reverse trends across the year. The long‐term recording run here on Ciona intestinalis sp. A provides novel insights into its population biology and ecology, and represents a valuable tool for sampling management and research planning.

“…The combination of temperature above 21 C and salinities below 18‰ reduces the survivorship of C. intestinalis (Carver et al, 2006;Vercaemer et al, 2011), which may explain why its abundance is low during summer but high during winter in Hong Kong. On the contrary, the tropical ascidian A. sydneiensis and H. momus that was largely recruited in summer may be limited by low temperatures.…”

“…Thus, NDX appears to have a weaker phenotypic effect than Ndi1. The temperature-difference in complementation efficiency may be due to the fact that C. intestinalis has a lower optimal temperature in its natural environment than S. cerevisiae [44][45][46]. However, NDX expression in Drosophila had a protective effect from both heat-and cold-stress, suggesting that it is less heat-labile than the fly's own cI.…”

An assembled cDNA coding for the putative single-subunit NADH dehydrogenase (NDX) of Ciona intestinalis was introduced into Drosophila melanogaster. The encoded protein was found to localize to mitochondria and to confer rotenone-insensitive substrate oxidation in organello. Transgenic flies exhibited increased resistance to menadione, starvation and temperature stress, and manifested a sex and diet-dependent increase in mean lifespan of 20-50%. However, NDX was able only weakly to complement the phenotypes produced by the knockdown of complex I subunits.
