“…This study showed that both heavy metal concentrations and stocks in S. salsa at MM and LM presented temporal fluctuations, and similar results were drawn by previous studies (Duman et al 2007;Ramirez et al 2001). The temporal variations of heavy metals in plants were generally dependent on metabolic factor ("dilution effect" during growth), biological characteristics, and environmental factors (such as levels of metals in sediment and interactions between metals and other elements).…”

To understand the temporal variations and bioaccumulation of heavy metals in the coastal marshes, the concentrations of heavy metals (Cr, Ni, Pb, and Cu) in the two Suaeda salsa marshes [middle S. salsa marsh (MM) and low S. salsa marsh (LM)] of the Yellow River estuary were determined from May to November in 2008 by in situ sampling and inductively coupled plasma mass spectrometry (ICP-MS) analysis. Results showed that heavy metal concentrations in S. salsa of MM and LM were generally in the order of Cu>Cr>Pb>Ni, while those in sediments fell in the order of Cr>Ni>Cu>Pb. Heavy metal concentrations of S. salsa in MM and LM were different, and significant differences were observed in stems (F = 4.797, p= 0.046) and litters (F=6.799, p=0.026) for Ni. Litter was the main stock of heavy metals, and the allocations of Cr, Ni, and Pb reached 31. .64 % (in LM), respectively. The ratios of roots/ leaves (R/L) and roots/stems (R/S) for Cr and Ni in MM were mostly greater than 1, while those ratios in LM were mostly less than 1, indicating that Cr and Ni in S. salsa at LM had greater mobility compared with those at MM. Moreover, the [accumulation factor, AF] plant of Cr, Ni, Cu, and Pb in LM, especially [AF] root and [AF] stem of Cr and [AF] litter of Ni, was also higher than that in MM. These indicated that S. salsa grown in LM was more suitable for potential biomonitor or phytoremediation of Cr, Ni, Cu, and Pb if intertidal sediments were seriously contaminated with an increase of pollutant loading (especially heavy metals) in the Yellow River estuary. The use of biomonitor (S. salsa) living and growing in LM could yield valuable information not only on the presence of anthropogenic stressors, but, more importantly, on the adverse influence the stressors are having on the environment.

“…Groenewald et al (1967) did not find any seasonal trend in the P concentration of C. apiculatum and C. mopane leaves, while Ramírez et al (2001) found that the mineral concentrations in shrub species in Mexico were generally higher in spring and summer than in the other seasons. No consistent seasonal pattern could be observed for any of the other minerals.…”

“…Due to higher Ca levels they measure an even wider Ca : P ratio than in the present study. Topps (1992) summarised the results of different studies on legume shrubs and trees in which wide Ca: P ratios of up to 21.3:1 were measured, and Ramírez et al (2001) reported similar wide Ca : P ratios for browse species in Mexico. Ruminants can tolerate a relatively wide Ca : P in the diet provided that the P intake is high (Underwood & Suttle, 1999).…”

The foliage of three Combretum species, C. apiculatum, C. molle and C. zeyheri, as well as that of Colophospermum mopane was collected over a period of two years. The chemical composition, in vitro organic matter digestibility (IVOMD) and the rumen degradability of dry matter (DM) and nitrogen (N) were determined on these samples. Mean values for crude protein (CP) concentration varied from 92 g/kg DM for C. molle to 141 mg/kg DM for C. mopane, the neutral detergent fibre concentration from 323 g/kg DM for C. apiculatum to 392 g/kg DM for C. molle and that of acid detergent fibre from 247 g/kg DM for C. apiculatum to 355 g/kg DM for C. molle. The calcium (Ca) concentration in the foliage was high (8-16 g/kg DM) compared to the phosphorus (P) concentrations of between 0.8-2.1 g/kg DM, resulting in an average Ca : P ratio of 9.3 : 1. The foliage contained relatively low levels of sodium (Na), 0.041 g/kg DM, based on beef cattle standards. The IVOMD ranged from 53% for C. mopane to 64% C. apiculatum and the rumen degradability of DM from 78% for C. molle to 94% for C. apiculatum. The DM degradability was substantially higher than that of nitrogen, which varied between 47% for C. apiculatum and 60% for C. zeyheri. It was concluded that the foliage tested would not be suitable sources of N to supplement protein deficiencies in low quality herbage. Furthermore, browsers would require additional sources of P and Na to avoid deficiencies in these elements.

The contents of Cu, Fe, Mn, and Zn were seasonally determined in the leaves of the native shrubs Á Castela erecta, Celtis pallida, Forestiera angustifolia, Lantana macropoda, and Zanthoxylum fagara Á that are browsed by the white-tailed deer (Odocoileus virginianus). The study was conducted at the Tamaulipan thornscrub region, northeastern Mexico, between summer 2004 and spring 2006. Leaf tissues were collected from three county sites (China, Linares, and Los Ramones). Mineral contents were measured using an atomic absorption spectrophotometer. All minerals, in all plants, were significantly different among sites, seasons, and years, as well as the double and triple interactions. In general, plants at the Linares site, that had the highest rainfall, had higher trace element content. Moreover, during the second year, all plant species were higher in micromineral content. Furthermore, during summer were also higher. Regardless of spatiotemporal variations, all plants had suitable levels of Fe and Mn to satisfy the adult range of white-tailed deer requirements. The Cu and Zn presented marginal deficiency in some plants especially during dry seasons (winter and spring). Seasonal variations in minerals could be associated to soil water deficits, excessive irradiance during summer, and extreme low temperatures during winter and spring that could have affected leaf development and micromineral concentrations.
