Ecological Indicators, 2023 Lift-off velocity, the wind speed at which a diaspore starts moving during secondary wind dispersal, representing diaspore mobile capacity, may greatly depend on vegetation where dispersal takes place.

Improving measurements of the falling trajectory and terminal velocity of wind‐dispersed seeds
Ecology and Evolution, 2022 Seed dispersal by wind is one of the most important dispersal mechanisms in plants. The key seed trait affecting seed dispersal by wind is the effective terminal velocity (hereafter “terminal velocity”, Vt), the maximum falling speed of a seed in still ...

Does Atta laevigata (Smith, 1858) act as Solanum lycocarpum seed dispersers?
Sociobiology, 2016 Ants can act as seed dispersers, modifying their distribution, affecting the reproductive success and the vegetation spatial structure. The leaf-cutting ants function, as dispersers of non-myrmecochorous plants, is little known.

Wind-Generated Seed Shadow in Southern Brazil: The Influence of the Mother Plant and Wind Direction
Floresta e Ambiente, 2020 Diaspore dispersal is an essential function of plant species, with effects on plant populations and natural forest dynamics. This study examines how traits of the mother plant (height, crown spread and distance from the diaspores) and the wind (wind ...

Dispersal of non-myrmecochorous plants by a >keystone disperser> ant in a Mediterranean habitat reveals asymmetric interdependence [PDF]
, 2012 In contrast to other plant-animal mutualisms, seed dispersal interactions, and particularly seed dispersal by ants, are generally considered asymmetric, non-specialized relationships in which dispersers depend less on plants than vice versa.

Influence of salinity and sediment resuspension on macrophyte germination in coastal lakes
Journal of Limnology, 2011 The vegetation as well as diaspore banks were investigated in two coastal lakes on the German Baltic Coast. The distribution of vegetation and diaspores was analysed at two depths (0.5, 1.5 m) on transects. Seedling densities and germination rates of the

Flirting diasporically: visits ‘home’ facilitating diasporic encounters and complex communities [PDF]
Journal of Ethnic and Migration Studies, 2017 While generations of Moroccan-origin Europeans have been a focus of policymakers seeking to 'integrate' them in their countries of dwelling, less attention has been paid to how visiting 'home' in Morocco - a perpetuating practice among Moroccan families living in Europe - contributes to their life course trajectories.

Alteration zonation in the Loma Blanca kaolin deposit, Los Menucos, Province of Rio Negro, Argentina [PDF]
, 2010 The Loma Blanca mine is in one of the northwest kaolinized zones of the Los Menucos area (Patagonia, Argentina). The parent rocks are andesites and andesitic tuffs from the Vera Formation, Los Menucos Group (Lower Triassic). Hayase & Maiza (1974)

Semiclassical atom theory applied to solid-state physics
, 2016 Using the semiclassical neutral atom theory, we extend to fourth order the modified gradient expansion of the exchange energy of density functional theory. This expansion can be applied both to large atoms and solid-state problems. Moreover, we show that
