“…Twenty intact seeds were randomly selected to measure the dimension, shape index, mass, projected area, wing loading and terminal velocity. Three dimensions (length, width and height) of each seed were measured using digital caliper (0.01 mm accuracy) (Zhu et al ., 2016). Seed mass was determined by electronic balance (0.1 mg accuracy).…”

“…Seed mass was determined by electronic balance (0.1 mg accuracy). Seeds were scanned and then analyzed by WinSEEDLE (Regent Instruments Inc., Canada) image analysis system to measure projected areas (PA) (Zhu et al ., 2016).

“…Seed dispersal trajectory may be influenced by wind conditions (wind speed and orientation), release height and seed traits such as seed weight, appendage, wind loading and terminal velocity (Savage et al ., 2014; Thomson et al ., 2011; Zhu et al ., 2016). Horizontal wind can disperse seeds far away from their mother plants (Augspurger, 1986; Soons et al ., 2004; vanDorp et al ., 1996).…”

“…In reality, wind conditions are so complicated that it is almost insurmountable to measure (Jones and Muller-Landau, 2008; Jongejans and Telenius, 2001). The wind tunnel, manufacturing controllable wind conditions, is necessary for quantifying the primary seed dispersal distance and distribution pattern (Dauer et al ., 2006; Zhu et al ., 2016). It can also be used to determine the dispersal trajectory if special facilities and techniques could be applied.…”

1 determine seed dispersal trajectory of Calligonum (Polygonaceae) 2 species 3 Wind speed, release height, seed morphology determine seed 4 dispersal trajectory 5 Abstract 26 How seed dispersal trajectory shifts with abiotic and biotic factors and what is the 27 relationship between seed dispersal distance and dispersal trajectory are remain 28 unclear. We used wind tunnel and video camera to track the seed dispersal trajectory 29 of 7 Calligonum species with different appendages under the different wind speeds 30 and the release heights. Dispersal trajectories and distances were determined by video 31 analysis and spatial coordinate transformation. Based on perspective principle, 4 32 modes of trajectories were determined. Wind speed, seed mass and release height 33 were the key factors determining seed dispersal trajectory modes. Release height and 34 wind speed tended to have the strongest explanatory power on seeds with bristles and 35 wings, respectively. Different trajectory modes lead to different dispersal distance, 36 while the same dispersal distance can be the result of different trajectory modes. The 37 proportion of species' trajectory modes formed its trajectory spectrum. Wind speed 38 tends to have strong influence on light and low-wind-loading seeds, release height 39 tends to have that on heavy and high-wind-loading seeds. Species with high 40 proportion of horizontal projectile and projectile have high dispersal capacity, vice 41 versa. Therefore, trajectory spectrum of a species reveals its primary dispersal 42 strategies and evolutionary consequences. 43

Citation: Moyano, J., M. A. Rodriguez-Cabal, and M. A. Nuñez. 2020. Highly invasive tree species are more dependent on mutualisms. Ecology 101(5):Abstract. Why some species become invasive while others do not remains an elusive question. It has been proposed that invasive species should depend less on mutualisms, because their spread would then be less constrained by the availability of mutualistic partners. We tested this idea with the genus Pinus, whose degree of invasiveness is known at the species level (being highly and negatively correlated with seed size), and which forms obligate mutualistic associations with ectomycorrhizal fungi (EMF). Mycorrhizal dependence is defined as the degree to which a plant needs the mycorrhizal fungi to show the maximum growth. In this regard, we use plant growth response to mycorrhizal fungi as a proxy for mycorrhizal dependence. We assessed the responsiveness of Pinus species to EMF using 1,206 contrasts published on 34 species, and matched these data with data on Pinus species invasiveness. Surprisingly, we found that species that are more invasive depend more on mutualisms (EMF). Seedling growth of species with smaller seeds benefited more from mutualisms, indicating a higher dependence. A higher reliance on EMF could be part of a strategy in which small-seeded species produce more seeds that can disperse further, and these species are likely to establish only if facilitated by mycorrhizal fungi. On the contrary, big-seeded species showed a lower dependence on EMF, which may be explained by their tolerance to stressful conditions during establishment. However, the limited dispersal of larger seeds may limit the spread of these species. We present strong evidence against a venerable belief in ecology that species that rely more on mutualisms are less prone to invade, and suggest that in certain circumstances greater reliance on mutualists can increase spread capacity.
