“…Commonly called African tulip tree, S. campanulata (here after Spathodea ) is a large tropical tree native to the wide Equatorial region of Africa (Smith, 1985). Spathodea trees introduced into the Pacific Islands originated from West Africa (Sutton et al, 2017). In 1998, Spathodea was designated a species threatening native biodiversity by the Government of French Polynesia (decree 244 CM of 12 February).…”

Long-distance dispersal is a key factor explaining the success of invasive alien species, particularly across oceanic islands. However, it is often not feasible to reliably measure long-distance seed dispersal (LDD) over many kilometers in the field. Here, we used a three-dimensional kinematic trajectory model (Computing Atmospheric Trajectory tool [CAT]) initiated on the basis of regional wind field data to assess the potential for LDD of a wind-dispersed invasive tree, Spathodea campanulata (African tulip tree), across the Society Islands (French Polynesia, South Pacific Ocean) following its initial planting and spread on the island of Tahiti. The main objective of our study was to determine whether S. campanulata could be expected to spread naturally among islands. Atmospheric dynamics, seed terminal velocity, precipitation, and temperature of air masses were considered to assess the potential for LDD between oceanic islands, with the island of Tahiti serving as the island source for multiple, geographically distant invasions. Aerial trajectories of modeled S. campanulata seeds indicated that wind-dispersed seeds originating from trees on the island of Tahiti could reach most of the Society Islands and disperse as far as 1364 km. This result suggests that Spathodea can be expected to spread naturally among the Society Islands. When rainfall events were modeled as causal agents of seed settlement, fewer seeds reached distant islands, but more seeds settled on the closest island (20 km away). Including effects of island topography ("barrier effects") also resulted in more seeds settling on the closest island and fewer seeds reaching the most distant islands. Overall, our findings suggest that recent atmospheric models can provide valuable insights into LDD and invasion patterns of wind-dispersed invasive species.

“…Natural enemies of C. macrocephalum in the Argentinean part of its native range have been targeted for use as biocontrol agents in South Africa (McConnachie et al, 2011). A close genetic relationship between native and exotic populations, as shown in Gitonga et al (2015) for Argentine and South African pompom weed, is favourable when selecting natural enemies for use as biocontrol agents (Sutton et al, 2017). Given the overlap in geographic distribution of ploidies in Argentina, it is likely that these agents have evolved within the range of polyploids in the native range.…”

“…The success of these biocontrol agents depends on their host specificity and whether they can control the complete genetic range of the weed in question. Matching alien invasive plant populations to source populations in their native range, greatly improves the accuracy of identifying and collecting host‐specific natural enemies for biocontrol in the introduced range (Sutton et al, 2017). AFLP genotyping and DNA sequencing revealed close genetic relationships between South African and Argentine C .…”

Two ploidy levels present in the invasive Campuloclinium macrocephalum (pompom weed) in South Africa – Implications for biocontrol

Campuloclinium macrocephalum (Less.) DC. (Asteraceae) is a perennial herb native to Central and South America (Goodall, 2016). It was first reported in South Africa in the early 1960s and was likely introduced either as an ornamental or through contaminated hay (McConnachie et al., 2011). Genetic evidence suggests that the pompom invasion may have resulted from multiple introductions mainly through Gauteng province in South Africa, with long-distance dispersal playing a major role in its spread across the country (Gitonga

A espatódea, é uma árvore de origem do oeste da África, muito utilizada para ornamentação, com florescimento amplo no verão e outono, com flores atrativas a abelhas, beija flores e outros insetos, porém seu néctar é considerado tóxico podendo ocasionar mortes de abelhas e outros polinizadores, quando há escassez de outras floradas, o que ocorre principalmente no final do outono e início do inverno, na região sul. Em 2019 a Assembleia Legislativa de Santa Catarina aprovou a Lei 17.694, que, “Proíbe a produção de mudas e o plantio da Spathodea campanulata”. Com o objetivo de registrar a ocorrência de espatódea no município de Santa Rosa do Sul, durante o processo de registro foi realizada a divulgação da lei para a população, com a orientação da substituição destas arvores por espécies nativas. Foi detectado a presença de 93 árvores de espatódea, com grande concentração na sede do município, e o desconhecimento da população quanto a legislação vigente.
