we examined the photosynthetic responses of submerged marestail in three lakes using pulse amplitude modulated (PAM) fluorometry. Three lakes were studied across a gradient of water temperature, with low water temperature conditions in Grass Lake and Arrow Bamboo Lake, and higher water temperature in Five Colored Lake. In the field, electron transport rates (ETRmax) were measured as rapid light curves (RLCs) by in situ yield measurements. Submerged marestail showed higher photosynthetic activity in Five Colored Lake compared to the other lakes, a response consistent with the adaptation of marestail in Five Colored Lake to high water temperature. The optimal temperature for photosynthesis of submerged marestail in Jiuzhaigou is about 12 °C. These results indicate that in different lakes the function of these aquatic plants is associated with a diversity of place-dependent environmental conditions, especially water temperature that leads to pronounced differences in the plant’s ecophysiological reactions.

AbstractIn this study, we report an unusual homing behavior of the Sichuan Partridge (Arborophila rufipectus) at the Laojunshan National Nature Reserve, Sichuan Province, China. Hen Sichuan Partridges led the chicks back to the nests where they hatched in the evening and roosted there over night. This behavior lasted 6.7 ± 4.3 nights (range = 1–15; n = 13) after the chicks hatched. At this stage, the hens became very vigilant to predators and human disturbance. If disturbed, they often abandoned the nests immediately and no longer returned thereafter. The ambient temperature at night during the early brooding period of Sichuan Partridge at our study site was ~ 12.4 °C. Our findings suggest that hen Sichuan Partridges may make trade-offs between nest predation risks versus the thermoregulatory needs of their young.

The Relationship

We used PAM fluorometry to examine photosynthetic rates of emergedHippuris vulgarisin two lakes characterized by different water temperature conditions. The photosynthetic response of emergedHippuris vulgariswas measured every 2 h throughout daily light cycle from dawn (7 am) to dusk (17 pm). Diurnal changes in the pattern of rapid-light curves (RLCs) were investigated in the field under ambient daylight. Electron transport rates were always significantly higher for emergedHippuris vulgarisin Five Colored Lake than that for plants in Arrow Bamboo Lake. Moreover, emergedHippuris vulgarisin Five Colored Lake had higher light saturation. Such a finding suggests higher photosynthetic activity in Five Colored Lake possibly in response to high water temperature. The relationship between the electron transport rates and temperature suggests that this species is strongly temperature -limited.
