“…Lin et al (2007) quantified the total N content of leaves of Aegiceras corniculatum, a mangrove plant from subtropical China, and found values from 0.30% to 1.80%, according to the age of the leaves (a mean value for mature leaves was 1.10%). Current results are also corroborated by Ellis et al (2006), who quantified values from 0.75% to 1.20% of total N in green leaves of L. racemosa. Even though mangrove plants are typically found in environments with rich nutrient Values represent the mean of three replicates ± SD (n = 3).…”

The quantification of total nitrogen in biological samples has wide applications in marine sciences. Different methods are currently used to quantify nitrogen content, but their accuracies have not been extensively tested with samples of marine origin. In this study, we compared results for total nitrogen analysis generated by the Hach method, a relatively new and low-cost technique, with CHN elemental analysis, a widely accepted and costly technique. Sixty aquatic organisms were tested covering substantial biological diversity, including algae, invertebrates, fishes, mangrove plants, salt marsh plants, and seagrasses. Two pure protein standards (bovine serum albumin and bovine milk casein) were also tested. All materials were tested using freeze-dried samples. Fishes showed the highest concentrations of nitrogen, with values always higher than 14%, whereas leaves of mangrove plants showed the poorest N content among all species (<2.0%). In general, animals showed higher values for total nitrogen than algae and spermatophytes. Results obtained with CHN analysis and the Hach method were compared for each species based on triplicate analyses for each method. Comparisons for each species showed no statistical differences between the techniques, which yielded virtually identical nitrogen measurements. In addition, results obtained with both CHN analysis and the Hach method for the two pure protein standards were similar to data provided by the manufacturer. The set of results indicates that the Hach method is suitable for nitrogen analysis of marine organisms and should be considered as an inexpensive and accurate alternative for nitrogen quantification.

“…According to Erickson et al (2004) leaves of Rhizophora mangle, Avicennia germinans and Laguncularia racemosa have N concentrations of 1.2, 1.8 and 1.0% (d.w.) respectively. Ellis et al (2006) reported N percentages ranging from 0.75 to 1.25% in sheets of L. racemosa. Low percentages of N in mangrove plants may be related to the high concentration of salt in the leaves, since these plants accumulate salt in the leaves and then eliminate them (Hogarth, 1999).…”

“…According to the tropical origin, climate warming may enable mangroves to extend their distribution to higher latitudes (Gilman et al 2008;Naidoo 2016). However, mangroves that lie along the latitudinal extremes of their distribution are still vulnerable to the extreme cold events (Ellis et al 2006;Gilman et al 2008, Saintilan et al 2014. In general, successive enhancement of low temperature is a typical characteristic of extreme cold events.…”

“…In general, successive enhancement of low temperature is a typical characteristic of extreme cold events. Several researches reported that low temperature, especially freezing stress, seriously influenced mangrove development and survival (Ellis et al 2006;Stuart et al 2006;Liu et al 2014). For example, a severe winter in Florida, occurred between the 1995 and 1996 growing seasons (minimum air temperature of −8°C in January 1996), killed 12% mangrove trees, and the severe freeze season occurred once approximately 8 years (Stevens et al 2006;Ross et al 2009).…”

Mechanisms on inhibition of photosynthesis in Kandelia obovata due to extreme cold events under climate change

Introduction: Mangroves that grow at the latitudinal extremes of their distribution are susceptible to extreme cold events. Successive enhancement of low temperature stress (seLTS) is a typical characteristic of extreme cold events. Low temperature stress can inhibit mangrove photosynthesis, which often inhibits the growth and development of mangroves. However, the possible reasons for impairment to photosynthesis of mangroves due to extreme cold events remain unclear. Methods: Kandelia obovata seedlings in a growth chamber were exposed to 5°C/−2°C (day/night) for 36 h (−2°C for 16 h) with 12 h light per day at 600 μmol m −2 s −1 photosynthetic photon flux density (PPFD) (a low temperature stress, aLTS), then the plants were transferred to the control condition (15°C/10°C (day/night) and allowed to recover for 5 days (R1). The other seedlings were subjected to low temperature treatment with a day/night temperature of 5°C/−1°C in a growth chamber for 24 h. Then these plants were transferred to 5°C/−2°C (day/night) under the same light and climate conditions for 36 h (two low temperature stresses, tLTS). Following the successive enhancement of low temperature treatment, these plants were returned to 15°C/10°C (day/night) for another 5-day recovery period (R2).
