“…The characteristics of pine species that are successful invaders, such as P. elliottii, include anemophily and anemochory, a high germination and productivity of the small seeds, a short chilling period required to overcome dormancy, a high seedling growth rate and short generation times (seven-year seed dispersal age with a three-year interval versus large-seed crops) (USDA, 1974;Richardson, 1996;Grotkopp et al, 2002;Richardson and Rejmanek, 2004).…”

“…Natural ecosystems invaded by pine occur in open phytophysiognomies or marginal habitats, such as grasslands, the vegetation of coastal sandy plains, dunes, scrubs, steppes, hilltops, savannas and lithological environments or disturbed areas in the pioneer stages of succession (Richardson and Bond, 1991;Richardson and Higgins, 1998;Zalba and Villamil, 2002). The 21 invasive Pinus species (Petit et al, 2004;Richardson and Rejmanek, 2004;Richardson, 2006), especially those of the sub-genus Diploxylon (Rejmanek and Richardson, 1996), are well documented to have high invasiveness in both the Northern (Richardson and Bond, 1991;Sturgess and Atkinson, 1993;Richardson and Higgins, 1998;Richardson and Rejmanek, 2004;Catling and Carbyn, 2005) and, particularly, Southern Hemisphere (Chilvers and Burdon, 1983;Corbett, 1991;Richardson et al, 1992;Richardson et al, 1994;Rejmanek and Richardson, 1996;Richardson and Higgins, 1998;Richardson and Rejmanek, 2004;Williams and Wardle, 2005;Richardson et al, 2008;Langdon et al, 2010;Simberloff et al, 2010). Richardson and Higgins (1998) verified the regular dispersion of Pinus seeds up to 8 km from its matrices and, occasionally, a more distant dispersal up to 25 km.…”

Pinus is the most invasive woody taxon, exceeded only by herbaceous plants. This study reports the reproductive biology and early establishment of Pinus elliottii Engelm. var.elliottii, describing its invasive properties in a protected natural area of the Brazilian coastal sandy plains. We evaluated the seed germination and rain, longevity of seed viability and the initial dynamics of the seedlings of Pinus elliottii var elliottii through field and laboratory experiments. We recorded a continuous seed rain of about 204.0 viable seeds m -2 per year, with a 90 % germination rate. The seeds exhibited a low longevity of viability in the soil and a dense, permanent seedling bank that may explain the high levels of pine invasion. The environmental impact caused by the pine's biological invasion suggests the recommendation for its immediate eradication, together with a restoration plan to restitute the native biodiversity gradually.

“…Disturbance events also provide windows of opportunity for invasive species 24 . Many invasive plant species are adapted to exploit temporarily favourable conditions through their short life cycles, rapid growth, high reproductive allocation, persistent soil seed banks and rapid germination (the Ideal Weed Hypothesis) 25 .…”

The Human Release Hypothesis for biological invasions: human activity as a determinant of the abundance of invasive plant species

et al. 2014

Research on biological invasions has increased rapidly over the past 30 years, generating numerous explanations of how species become invasive. While the mechanisms of invasive species establishment are well studied, the mechanisms driving abundance patterns (i.e. patterns of population density) remain poorly understood. Invasive species typically have higher abundances in their new environments than in their native ranges, and patterns of invasive species abundance differ between invaded regions. To explain differences in invasive species abundance, we propose the Human Release Hypothesis. In parallel to the established Enemy Release Hypothesis, this hypothesis states that the abundance of invasive species may be partly explained by the level of human activity or landscape maintenance, with intermediate levels of human activity providing optimal conditions for high abundance. The Human Release Hypothesis does not negate other important drivers of species invasions, but rather should be considered as a potentially important additional or complementary mechanism. We illustrate the hypothesis via a case study on an invasive rose species, and hypothesize which locations globally may be most likely to support high abundances of invasive species. We propose that more extensive empirical work on the Human Release Hypothesis could be useful to test its general applicability.

“…Many studies of plant competitive ability, fecundity, and invasiveness have attempted to detect the life-history strategies that contribute to successful competitors and invaders (Rejmánek & Richardson, 1996;Gerlach & Rice, 2003). One approach involves comparative studies of weedy and nonweedy species (Baker, 1965;Crawley et al ., 1996;Williamson & Fitter, 1996;Sutherland, 2004).…”

Competition alters life history and increases the relative fecundity of crop–wild radish hybrids (Raphanusspp.)

Summary• The evolutionary impact of crop-to-wild gene flow depends on the fitness of hybrids under natural, competitive conditions. Here, we measured the performance of third-generation (F 3 ) radish hybrids ( Raphanus raphanistrum × Raphanus sativus ) and weedy R. raphanistrum to understand how competitive interactions affect life history and relative fecundity.• Three wild and three F 1 crop-wild hybrid radish populations were established in semi-natural, agricultural conditions in Michigan, USA. The effects of competition on life-history traits and fecundity of F 3 progeny were measured 2 yr later in a common garden experiment.• Third-generation hybrid plants generally produced fewer seeds per fruit and set fewer fruits per flower than wild plants, resulting in lower lifetime fecundity. With increasing competition, age at reproduction was delayed, the relative number of seeds per fruit was reduced in wild plants and differences between hybrid and wild fecundity diminished.• Competition may enhance the fecundity of advanced-generation hybrids relative to wild plants by reducing differences in life history, potentially promoting the introgression of crop alleles into weed populations.
