The Impact

The brown marmorated stink bug (BMSB) Halyomorpha halys (Heteroptera: Pentatomidae) is an invasive pest in North America and Europe that damages many plant species and invades human dwellings. It is regularly intercepted at Aotearoa/New Zealand’s borders but is not yet known to have established. Māori are partners in New Zealand’s biosecurity community and an understanding of the potential impact of any invasive alien species to their interests is essential. The known impacts of BMSB in published literature were reviewed with a focus on Māori plant taonga (valued or treasured plant species) in: (1) Māori commercial enterprises; (2) mara kai (food gardens); and (3) the natural estate. Many fruit and some vegetable species are likely to be affected by BMSB in commercial and non-commercial Māori horticulture but the impact of BMSB on indigenous/native and other taonga plant species in mara kai and the native estate is difficult to evaluate. BMSB poses a serious economic threat to some crop species of commercial value to Māori, as well as threat to some native taonga species. A kaupapa Māori approach examining unpublished mātauranga (knowledge) would considerably broaden this understanding. He ngārara raupatu kaha nei i te tini o ngā tipu, te urutomo noa i te hunga tangata te ngārara nei. Ka kaha haukotingia te ngārara nei e te mana ārai o Aotearoa heoi anō, kāore anō kia whakawhenua i a ia.

Lantana camara L. (Verbenaceae) is native to tropical America and has been introduced into many other countries as an ornamental and hedge plant. The species has been spreading quickly and has naturalized in more than 60 countries as an invasive noxious weed. It is considered to be one of the world’s 100 worst alien species. L. camara often forms dense monospecies stands through the interruption of the regeneration process of indigenous plant species. Allelopathy of L. camara has been reported to play a crucial role in its invasiveness. The extracts, essential oil, leachates, residues, and rhizosphere soil of L. camara suppressed the germination and growth of other plant species. Several allelochemicals, such as phenolic compounds, sesquiterpenes, triterpenes, and a flavonoid, were identified in the extracts, essential oil, residues, and rhizosphere soil of L. camara. The evidence also suggests that some of those allelochemicals in L. camara are probably released into the rhizosphere soil under the canopy and neighboring environments during the decomposition process of the residues and as leachates and volatile compounds from living plant parts of L. camara. The released allelochemicals may suppress the regeneration process of indigenous plant species by decreasing their germination and seedling growth and increasing their mortality. Therefore, the allelopathic property of L. camara may support its invasive potential and formation of dense monospecies stands.

The Impact

Climate change has impacted biodiversity, affecting species and altering their geographical distribution. Besides understanding the impact in the species, it has been advocated that answering if different traits will be differently impacted could allow refined predictions of how climate change will jeopardize biodiversity. Our aim was to evaluate if climate change will potentially impact plant species differently, considering their traits. We evaluated 608 plant species that occur in the naturally open areas of ferruginous outcrops (namely, cangas) in the National Forest of Carajás (Eastern Amazon). Firstly, we estimated the effects of climate change on each species using species distribution modeling, and analyzed this impact in the set containing all species. Secondly, we classified plant species considering the following traits: (i) pollination syndromes (melittophily, phalaenophily, psychophily, cantharophily, entomophily, ornithophily, chiropterophily, anemophily); (ii) habit (tree, shrub, herb, liana, parasite); and (iii) the main habitat of occurrence (open areas and forests). Thirdly, we investigated if the effects of climate change could be significantly more intense considering all the different traits quoted. Our results showed that most plant species will potentially face reduction of suitable habitats under future climate and the scenarios showed that 42% of them may not find suitable areas in the cangas of Carajás. We found no significant difference within each analyzed trait, considering the potential impact of climate change. The most climatically suitable areas (i.e., areas with high probability of species occurrence in the future) are those in the southwest of the study area. These areas can be considered as priority areas for species protection against climate change.
