“…Nevertheless, extensive insect herbivory damage to all Ni hyperaccumulator species in Sabah was observed during this study. Specialist insect herbivores may feed on Ni hyperaccumulators without negative effects (Boyd 2009), and one geometric moth species (Erebidae: Erebinae tribe Poaphilini) has been found in this study to feed exclusively on the Ni hyperaccumulator Phyllanthus balgooyi (illustrated in Fig. 3, top).…”

“…The 'Elemental Herbivory Defense' hypothesis (Boyd and Martens 1998;Boyd 2009) suggests that high Ni loading in the leaves of Ni hyperaccumulators could result in reduced (insect) herbivory attack. However, field observations on Mount Bloomfield, Palawan (Philippines), showed that Ni hyperaccumulators did not experience less herbivory (Proctor et al 2000), and the Ni hyperaccumulator Shorea tenuiramulosa suffered as much foliar herbivory damage as 'normal' plant species growing in the area on Mount Silam in Sabah (Proctor et al 1989).…”

Ecology of nickel hyperaccumulator plants from ultramafic soils in Sabah (Malaysia)

Sabah (Malaysia) has one of the largest surface expressions of ultramafic rocks on Earth and in parallel hosts one of the most species-rich floras. Despite the extensive knowledge of the botanical diversity and the chemistry of these substrates, until recently the records for nickel (Ni) hyperaccumulator plants in the area have been scant. Recent intensive screening has resulted in 19 new records, adding to the 5 previously known from Sabah. The results of this study indicate that most Ni hyperaccumulator plants in Sabah are restricted to successional habitats (ridges, river banks, secondary vegetation) at elevations \1200 m a.s.l. Moreover, Ni hyperaccumulators are locally common both in terms of number of individuals and relative number of species. Nickel hyperaccumulation oc-

“…There is indeed evidence that ecological partners of hyperaccumulators have evolved resistance to the hyperaccumulated element. For example, Boyd (2009) reported insects that feed almost exclusively on Ni hyperaccumulators. He identified 15 insect species across three (sub)orders that can tolerate an internal Ni concentration of ≥500 mg/kg −1 .…”

“…Beetles were killed immediately after collection and then dried at 65 o C for 72 h. Analyzing insects immediately after collection means that metal in the gut contents will be included in the measurements (Migula et al, 2007), yet whole-body measurements that include gut contents are relevant measures of the metal dose received by a predator that consumes entire insect prey (Boyd, 2009). Four composite samples of dried beetles were analyzed for their whole-body metal concentrations (Wall & Boyd, 2002).…”

Host plant selection of Chrysolina clathrata (Coleoptera: Chrysomelidae) from Mpumalanga, South AfricaAbstract Hyperaccumulated elements such as Ni may defend plants against some natural enemies whereas other enemies may circumvent this defense. The Ni hyperaccumulator Berkheya coddii Roessler (Asteraceae) is a host plant species for Chrysolina clathrata (Clark), which suffers no apparent harm by consuming its leaf tissue. Beetle specimens collected from B. coddii had a whole body Ni concentration of 260 +g/g dry weight, despite consuming leaf material containing 15 100 +g Ni/g. Two experiments were conducted with adults of this beetle species: a no-choice experiment and a choice experiment. In the nochoice experiment we offered beetles foliage of one of four species of Berkheya: B. coddii, B. rehmannii Thell. var. rogersiana Thell., B. echinacea (Harv.) O. Hoffm. ex Burtt Davey, and B. insignis (Harv.) Thell. The two former species are Ni hyperaccumulators (defined as having leaf Ni concentration > 1 000 +g/g) whereas the latter have low Ni levels (< 200 +g/g) in their leaves. Masses of beetles were monitored for 6 days. Choice experiments used growing stem tips from the same Berkheya species, placed into Petri dishes with five Chrysolina beetles in each, and the amount of feeding damage caused on each of the four species was recorded. Beetles in the no-choice experiment gained mass when offered B. coddii, maintained mass on leaves of the other Ni hyperaccumulator (B. rehmannii var. rogersiana), and lost mass when offered non-hyperaccumulator leaves. In the choice test, beetles strongly preferred B. coddii to other Berkheya species. We conclude that C. clathrata may be host-specific on B. coddii.

High‐nickel insects and nickel hyperaccumulator plants: A review

Abstract: Insects can vary greatly in whole-body elemental concentrations. Recent investigations of insects associated with Ni hyperaccumulator plants have identified insects with relatively elevated whole-body Ni levels.
