“…These results are in agreement with previous studies reporting Ni concentrations in A. pintodasilvae (Brooks and Radford, 1978;Gonçalves et al, 2007;Menezes de Sequeira and Pinto da Silva, 1992;Peterson et al, 2003). Given the bias towards studies concerning hyperaccumulators, Ni concentrations in non-hyperaccumulators are seldom reported.…”

“…Dudley, 1986) is an endemic taxon of the serpentine outcrops in northeast Portugal. This Ni hyperaccumulator (Brooks et al, 1981;Menezes de Sequeira and Pinto da Silva, 1992) can reach more than 50% cover in some locations (Aguiar et al, 1998) and contributes to the flux of Ni to herbivore and carnivore trophic levels in these areas (Peterson et al, 2003). The ecological function and evolutionary value of Ni hyperaccumulation in A. pintodasilvae has already received some attention, with defense hypothesis gathering support.…”

• The defense hypothesis of Ni hyperaccumulation was tested in Alyssum pintodasilvae.• We compared the effects of A. pintodasilvae and A. simplex on Tribolium castaneum.• No-choice and choice tests were performed using diet disks amended with leaves.• Both high-Ni and low-Ni plants caused significant antifeedant effects on Tribolium.a b s t r a c t a r t i c l e i n f o The defense hypothesis is commonly used to explain the adaptive role of metal hyperaccumulation. We tested this hypothesis using two Brassicaceae congeneric species: Alyssum pintodasilvae, a Ni hyperaccumulator, and the non-accumulator Alyssum simplex both growing on serpentine soils in Portugal. Artificial diet disks amended with powdered leaves from each plant species were used to compare the performance (mortality, biomass change) and feeding behavior of Tribolium castaneum in no-choice and choice tests. The performance of T. castaneum was not affected at several concentrations of A. pintodasilvae or A. simplex in no-choice tests. However, the consumption of plant-amended disks was significantly lower than that of control disks, irrespectively of the species fed. Accordingly, when insects were given an alternative food choice, disks of both plant species were significantly less consumed than control disks. Moreover, insects did not discriminate between disks in the combination "A. pintodasilvae + A. simplex". Contrary to our expectations, these results suggest that both plant species have equally effective defenses against herbivory. While Ni is believed to be part of the deterrence mechanism in the hyperaccumulator A. pintodasilvae, it seems likely that organic compounds, possibly glucosinolates, play an important role in the defense of A. simplex or in both species.

“…HM transfer along the trophic chain has been reported, for example for the Ni hyperaccumulator plant Alyssum pintodalsilvae (Brassicaceae), that transfers Ni to grasshoppers (herbivore) and spiders (carnivorous insect), having the spiders higher Ni concentrations [69]. Similar results were reported by Boyd and Wall [66].…”

Heavy Metals

Heavy metals exert their toxic effects through different mechanisms. Lately, increasing attention has been focused on understanding the long-term ecological effects of chronically exposed populations and communities and their consequences to the ecosystem. The long-term exposure to heavy metals in the environment represents a threat to wild populations, affecting communities and putting ecosystem integrity at risk. Therefore, this type of exposure represents a threat to biodiversity. In the field, metal exposure is generally characterized by low doses and chronic exposures. This type of exposure exerts alterations across levels of biological organization. Distribution and abundance of populations, the community structure and the ecosystem dynamics may be altered. This chapter will focus on how chronically metal exposures in the field affect negatively populations and communities becoming a threat to biodiversity. Also, attention is put on the tools that enable to characterize and analyze the detrimental effects of heavy metal exposure on wild populations. Hence, the use and development of biomarkers in ecotoxicology will be discussed.

“…In a study conducted in an ultramafi c (serpentine) soil, where a Ni hyperaccumulating plant (Alyssum pintodasilvae T. R. Dudley) was common, herbivores such as grasshoppers and predators such as spiders had signifi cantly elevated concentrations of Ni [98]. In contrast, the concentrations of Cr and Co, which are also enriched in ultramafi c soils, but are not accumulated by A. pintodasilvaea, were not elevated in the studied invertebrates.…”
