“…For example, tropical isolates of a green macrophyte were photoinhibited at suboptimal low temperatures, where they grew at 30% of their maximal growth rate (Eggert et al, 2006). In contrast, supraoptimal temperatures of 30 C were not photoinhibiting.…”

The freshwater cyanobacterium Cylindrospermopsis raciborskii spreads from tropical to temperate regions worldwide. This entails acclimation to varied light and temperature conditions. We studied the thermal and light acclimation of the photosynthetic machinery of C. raciborskii by monitoring alteration of the chlorophyll a and carotenoid content in German strains of C. raciborskii, in African and Australian strains of C. raciborskii, and in German strains of Aphanizomenon gracile, a native cyanobacterium belonging to the same order (Nostocales). Our results showed that temperate and tropical C. raciborskii strains did not differ in pigment acclimation to light and temperature. In contrast, the ratio of photoprotective carotenoids (namely the carotenoid glycoside 4-hydroxymyxol glycoside [aphanizophyll]) to chlorophyll a increased significantly more in C. raciborskii in comparison with A. gracile (1) with decreasing temperatures from 20 to 10 C and a moderate light intensity of 80 mmol photons m À2 s À1 and (2) with increasing light intensities at a suboptimal temperature of 15 C, compared to 20 C.We conclude that below 20 C photoinhibition is avoided by greater photoprotection in the invasive species C. raciborskii compared to the native species A. gracile.

“…Accordingly, seaweeds native to habitats with large annual temperature variations typically display a stronger ability to acclimate than species from habitats with more stable seasonal regimes. Seasonal acclimation of photosynthesis has been described for seaweeds from the temperate regions (Davison 1987;K€ ubler and Davison 1995;Pfetzing et al 2000;Eggert et al 2006;Padilla-Gamiňo and Carpenter 2007). Likewise, acclimation has been described in a number of intertidal species (Smith and Berry 1986;Kim et al 2009;Henkel et al 2009).…”

“…Likewise, acclimation has been described in a number of intertidal species (Smith and Berry 1986;Kim et al 2009;Henkel et al 2009). In contrast, a limited acclimation potential has been described for Antarctic and tropical species (Eggert and Wiencke 2000;Eggert et al 2006). The fact that temperature changes can induce cellular acclimation responses indicates that temperature is sensed and that the temperature signal is immediately transduced into the cell.…”

“…3.2b). Temperate populations of Valonia utricularis (Chlorophyta, Eggert et al 2006) and Asparagopsis taxiformis (Rhodophyta, Padilla-Gamiňo and Carpenter 2007) displayed seasonal (partial) temperature acclimation of photosynthesis, whereas tropical individuals of both species did not. Alternatively, the hypothesis "Colder is better" predicts that an organism acclimated to a low-temperature environment will always have a performance advantage over another organism held at a warmer environment (Fig.…”

Seaweed Responses to Temperature

"Why don't seaweeds spread beyond their present boundaries along an uninterrupted rocky coastline?", asked Breeman in 1988. Two principal aspects play a central role in shaping biogeographical distribution patterns: temperature-dependent effects on performance (e.g., growth, photosynthesis) and temperature tolerance (i.e., survival). The temperature responses of species are often correlated with the local thermal environments, i.e., species are locally adapted, but may vary seasonally or among populations or life stages due to phenotypic plasticity. Accordingly, it is necessary to differentiate three types of temperature responses: (1) genetic adaptation to local conditions, (2) phenotypic acclimation in response to variation of environmental conditions, and (3) short-term physiological regulation. The responses take place over different timescales: seconds to minutes (regulation), hours to days (acclimation), and up to thousands of millions of years (adaptation). This chapter reviews the temperature responses of seaweeds and their biogeographical implications. Local Temperature Adaptation of Growth and PhotosynthesisThe effect of temperature on performance traits, such as growth and photosynthesis, is typically visualized using temperature-response curves. Both growth and photosynthetic rates of seaweeds increase with temperature, plateau at a maximal level, A. Eggert (*)

“…In fact, the filtration process used for water from Lake Taihu is expected to more effectively capture small algal cells (effective pore size 0.45 lm vs. 1.2 lm for Lake Okeechobee) including picocyanbacteria and small flagellates, and likewise ethanol is expected to extract more CHL, not less (Sartory & Grobbelaar, 1984). The CHL differences may be explained by the colder water temperature during the winter in Lake Taihu, which can reduce phytoplankton growth (Falk et al, 2004;Eggert et al, 2006). This hypothesis also could explain the massive algal bloom that occurred in Lake Taihu in 2007.…”

Comparative analysis of nutrients, chlorophyll and transparency in two large shallow lakes (Lake Taihu, P.R. China and Lake Okeechobee, USA)

This article compares limnological attributes of two of the world's largest shallow lakesLake Okeechobee in Florida, USA and Lake Taihu in P.R. China. Both the systems support an array of ecological and societal values including fish and wildlife habitat, public water supply, flood protection, and recreation. Both have extensive research programs, largely because of concern regarding the lakes' frequent cyanobacterial blooms. By evaluating these systems together, we compare and contrast properties that can generally advance the understanding and management of large shallow lowland lakes. Because of shallow depth, long fetch, and unconsolidated mud sediments, water chemistry, and transparency in both the lakes are strongly influenced by resuspended sediments that affect light and nutrient conditions. In the central region of both the lakes, where depth is the greatest, evaluation of limiting factors by a trophic state index approach indicates that light most often limits phytoplankton biomass. In contrast, the more sheltered shoreline areas of both the lakes display evidence of nitrogen (N) limitation, which also has been confirmed in nutrient assays conducted in earlier studies. This N limitation most likely is a result of excessive levels of phosphorus (P) that have developed in the lakes due to high external loads over recent decades and the currently high internal P recycling. Comparisons of these lakes show that Lake Taihu has higher N than, similar total phosphorus (TP) and similar light conditions to that of Lake Okeechobee, but less chlorophyll a (CHL). The latter may be as a result of lower winter temperatures in Lake Taihu (around 5°C) compared to Lake Okeechobee (around 15°C), which could reduce phytoplankton growth and abundance through the other seasons of the year. In these systems, the important role of light, temperature, and nutrients in algal bloom dynamics must be considered, especially due to possible adverse and unintended effects that might occur with projects such as sediment removal, and in the long term, in regard to buffering lake responses to external load reduction.
