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 ...

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

Diaspore: Diagnosing Performance Interference in Apache Spark

IEEE Access, 2021
Apache Spark is being increasingly used to execute big data applications on cluster computing platforms. To increase system utilization, cluster operators often configure their clusters such that multiple co-located applications can simultaneously share ...

Padrões morfológicos de diásporos de árvores e arvoretas zoocóricas no Parque Estadual de Itapuã, RS, Brasil Morphological patterns of diaspores from animal-dispersed tree and treelet species at Parque Estadual de Itapuã, Rio Grande do Sul State, Brazil

Acta Botânica Brasílica, 2008
Diásporos são as unidades de dispersão das plantas e sua morfologia está relacionada a adaptações às estratégias de dispersão e estabelecimento. Neste estudo, foram avaliadas características morfológicas de diásporos de 64 espécies de árvores e arvoretas

The influence of vegetation structure on lift-off velocity of diaspores during secondary wind dispersal

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.

Determination of Geochemical Bio-Signatures in Mars-Like Basaltic Environments [PDF]

, 2017
Bio-signatures play a central role in determining whether life existed on early Mars. Using a terrestrial basalt as a compositional analog for the martian surface, we applied a combination of experimental microbiology and thermochemical modeling ...

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.

Seed Dispersal by Ants in Three Early-Flowering Plants

Insects, 2022
Interactions between ants and plants vary from being occasionally beneficial to neutral and negative. Ant-mediated dispersal of obligatory myrmecochorous plants is considered mutualistic interaction, providing benefits to plants in terms of seed ...

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
