“…‘future’ temperature conditions at our northernmost site) and three site treatments (south, central and north), for a total of 86 pots for the nonnative species and 105 pots each for the native species. Eight to nine replicate pots per treatment were made for the native species ( Table 1a ), and seven replicate pots were made per treatment for the nonnative species ( Table 1b ), as the native species have lower germination rates, relative to the nonnative Eugenia species ( Stricker and Stiling 2013 ). The potting dates were 27 January 2012, for the native species, and 9 May 2012, for the nonnative species, in accord with their fruiting phenology and when the seeds were collected.…”

The influence of warming and biotic interactions on the potential for range expansion of native and nonnative species

Plant species ranges are expected to shift in response to climate change, however it is unclear how species interactions will affect range shifts. Because of the potential for enemy release of invasive non-native plant species from species-specific soil pathogens, invasive plants may be able to shift ranges more readily than native plant species. Additionally, changing climatic conditions may alter soil microbial functioning, affecting plant-microbe interactions. We evaluated the effects of site, plant-soil microbe interactions, altered climate, and their interactions on the growth and germination of three congeneric shrub species, two native to southern and central Florida (Eugenia foetida and E. axillaris), and one non-native invasive from south America (E. uniflora). We measured germination and biomass for these plant species in growth chambers grown under live and sterile soils from two sites within their current range, and one site in their expected range, simulating current (2010) and predicted future (2050) spring growing season temperatures in the new range. Soil microbes (microscopic bacteria, fungi, viruses and other organisms) had a net negative effect on the invasive plant, E. uniflora, across all sites and temperature treatments. This negative response to soil microbes suggests that E. uniflora’s invasive success and potential for range expansion are due to other contributing factors, e.g. higher germination and growth relative to native Eugenia. The effect of soil microbes on the native species depended on the geographic provenance of the microbes, and this may influence range expansion of these native species.

“…Other well-described hypotheses that will not be discussed in detail in this review provide explanations of how populations with low genetic diversity can become invasive and include pre-adaptation ( Dlugosch and Parker, 2007 ; Clark et al ., 2013 ; Dostál et al ., 2013 ), phenotypic plasticity and enhanced resource availability ( Callaway and Aschehoug, 2000 ; Graebner et al ., 2012 ; Stricker and Stiling, 2013 ), natural enemy release ( Hinz et al ., 2012 ) or a combination of factors ( Geng et al ., 2007 ; Eriksen et al ., 2012 ; Vergeer and Kunin, 2013 ). Additional studies on the roles of breeding system and pollinator interactions may shed light on these successfully inbreeding invasive plants.…”

Understanding invasion history and predicting invasive niches using genetic sequencing technology in Australia: case studies from Cucurbitaceae and Boraginaceae

The development of genetic profiles of invading plants can provide insight towards a better understanding of niche utilization. Recent advances in sequencing techniques have greatly facilitated genetic assessment and profiling. Here we review our recent studies on selected Australian Cucurbitaceae and Boraginaceae to demonstrate the application of genetic sequencing across a selection of invasive Australian plants.

“…However, the difference in germination success was not statistically significant under controlled laboratory conditions compared to field conditions, and relative growth rates also did not differ significantly between the two species. Stricker and Stiling (2013) found that in garden experiments as well as in the field, seedling emergence, survival, and rate of growth in height were higher for the exotic Eugenia uniflora, which is considered invasive in Florida, compared to the native E. axillaris and E. foetida. In this study, we explored the differences in seed germination, seedling survival, and seedling growth traits between a native and a non-native species of two genera that are in distantly related families-Macaranga (family: Euphorbiaceae) and Cecropia (family: Urticaceae; see APG III 2009)-but share ecological characteristics as tropical, pioneer tree species.…”

Comparing germination success and seedling traits between exotic and native pioneers: Cecropia pachystachya versus Macaranga gigantea

Cecropia is a pioneer genus from the Neotropics, whilst Macaranga is an ecological analog with a center of distribution in Southeast Asia. In the past few decades, introduced populations of Cecropia spp. have spread rapidly in Singapore, Malaysia, and Indonesia. In Singapore, Cecropia pachystachya now occupies habitats that would have been expected to be occupied by Macaranga gigantea. We conducted germination experiments under 0, 20, 50, and 70 % shading and measured the survival rates and functional traits of the seedlings of these two species from material collected in Singapore. Seeds of C. pachystachya germinated in 3-12 days, whereas seeds of M. gigantea germinated from day 13 onwards. Germination success for C. pachystachya was between 90.3 % under fulllight conditions and 55.8 % under 50 % shading, while for M. gigantea only 69.1 % of seed germinated under full-light conditions and germination completely failed when seeds were shaded by 20 % or more. The seedlings of C. pachystachya also had higher survival rates, faster shoot and root biomass accumulation, larger leaves, and lower total water content than those of M. gigantea. Thus overall, C. pachystachya possesses traits that may provide a competitive edge over the native M. gigantea and will be advantageous for its spread given the increasing proliferation of disturbed landscapes in tropical Southeast Asia.
