- Description:
- Five species of acanthocephalans of the family Centrorhynchidae are recorded from birds in Bulgaria: Centrorhynchus amphihius Das, 1950 from Buteo buteo (L.) (new host record), C. glohocaudatus (Zeder. 1800) Luhe, 1911 from Falco tin-nunculus L. and F. vespertinus L, (new host record), Sphaerimstris picae (Rudolphi, 1819) Golvan, 1960 from Pica pica (L.) and Lanius excuhitor L. (new host record), S. lancea (Westrumb, 1821) Golvan, 1960 from Vanellus vanellus (L.), and S. turili (Yamaguti, 1939) Golvan, 1960 from Turdus merula L„ Cinclus cinclus (L.) (new host record) and Stumus vulgaris L. (new host record). New geographical record for Europe is this of C. amphihius, and for Bulgaria - this of S. lurdi. The species are described and figured on the basis of Bulgarian specimens. Sphaerimstris picae is recognized as a valid species and S. teres is considered its synonym. A male of S. picae with a copulatory cap is reported.

- Description:
- A new species of Acanthochondria Oakley, 1927 (Copepoda, Poecilostomatoida, Chondracanthidae), parasitic on Serranus auriga (Cuvier) from the Argentinean coastal zone, is described and illustrated. The new species differs from its congeners by the relative length of the neck and the protopod of leg 2. This is the second record of this genus for the South-eastern Atlantic and the first one from a serranid host.

- Description:
- The effect of ultraviolet B radiation (UV-B) on cellular ultrastructure, chlorophyll (Chl), carotenoids, and total phenolics of Acrostichum danaeifolium gametophytes was analyzed. The control group of spores was germinated under standard conditions, while the test group of spores was germinated with additional UV-B for 30 min every day for 34 d. The cell characteristics were preserved in gametophytes irradiated with UV-B, but the number of starch grains increased in the chloroplasts and the more developed grana organization in contrast to the chloroplasts of the control group. Chl a content decreased, while Chl b content increased in the gametophytes cultivated with UV-B for 34 d. Contents of lutein and zeaxanthin decreased and trans-β-carotene concentration was enhanced in the gametophytes irradiated with UV-B. The content of total phenolic compounds increased in the gametophytes cultivated with UV-B. Therefore our data suggest that the gametophytes of A. danaeifolium, a fern endemic to the mangrove biome, were sensitive to enhancement of UV-B radiation at the beginning of their development and they exhibited alterations in their ultrastructure, pigment contents, and protective mechanisms of the photosynthetic apparatus, when exposed to this radiation., A.

1389. Acclimation of C3 photosynthesis to elevated CO2: hypotheses and experimental evidence
- Creator:
- Reining, E.
- Format:
- Type:
- model:internalpart and TEXT
- Language:
- Multiple languages
- Description:
- Acclimation of the photosynthesis of C3 plants to elevated atmospheric CO2 concentrations is ffequently observed. Some hypotheses ffequently proposed to explain this phenomenon are: (7) stomatal closure; (2) inhibition of photosynthesis by starch accumulation, and (5) reduced activity or concentration of ribulose-1,5- bisphosphate carboxylase/oxygenase. These hypotheses are compared with experimental evidence ffom the literature.

- Description:
- a1_The aim of this work was to study the acclimation of photosynthesis in a boreal grass (Phalaris arundinacea L.) grown in controlled environment chambers under elevated temperature (ambient + 3.5°C) and CO2 (700 μmol mol-1) with varying soil water regimes. More specifically, we studied, during two development stages (early: heading; late: florescence completed), how the temperature response of light-saturated net photosynthetic rate (Psat), maximum rate of ribulose-1,5-bisphosphate carboxylase/oxygenase activity (Vcmax) and potential rate of electron transport (Jmax) acclimatized to the changed environment. During the early growing period, we found a greater temperature-induced enhancement of Psat at higher measurement temperatures, which disappeared during the late stage. Under elevated growth temperature, Vcmax and Jmax at lower measurement temperatures (5-15°C) were lower than those under ambient growth temperature during the early period. When the measurements were done at 20-30°C, the situation was the opposite. During the late growing period, Vcmax and Jmax under elevated growth temperature were consistently lower across measurement temperatures. CO2 enrichment significantly increased Psat with higher intercellular CO2 compared to ambient CO2 treatment, however, elevated CO2 slightly decreased Vcmax and Jmax across measurement temperatures, probably due to down-regulation acclimation. For two growing periods, soil water availability affected the variation in photosynthesis and biochemical parameters much more than climatic treatment did. Over two growing periods, Vcmax and Jmax were on average 36.4 and 30.6%, respectively, lower with low water availability compared to high water availability across measurement temperatures. During the late growing period, elevated growth temperature further reduced the photosynthesis under low water availability., a2_Vcmax and Jmax declined along with the decrease in nitrogen content of leaves as growing period progressed, regardless of climatic treatment and water regime. We suggest that, for grass species, seasonal acclimation of the photosynthetic parameters under varying environmental conditions needed to be identified to fairly estimate the whole-life photosynthesis., Z.-M.
