Diasporescence in rubies from Prilep dolomitic marble
Macedonian Journal of Chemistry and Chemical Engineering, 2015 Rubies from the Prilep dolomitic marble contain numerous diaspore inclusions, resulting from oriented intergrowth with corundum. In the world of gemstones, this phenomenon has been recognized as diasporescence, which has to date been researched only in ...

Plant dispersal across the tropical Atlantic by wind and sea currents [PDF]
, 2004 This review brings together evidence on the monophyly and ages of angiosperm lineages ranging across the tropical Atlantic with data on the direction, strength, and speed of sea currents and wind jets across that ocean. Mainly for pragmatic reasons (data

Frontiers in Ecology and Evolution, 2020 Seed dispersal is a vital part of a plant’s life cycle that enables progeny to reach new sites suitable for burial and establishment. Awns are characteristic of many grass species and enable diaspores to self-disperse. Little is known, however, about the

ABA-Induced Vegetative Diaspore Formation in Physcomitrella patens
Frontiers in Plant Science, 2019 The phytohormone abscisic acid (ABA) is a pivotal regulator of gene expression in response to various environmental stresses such as desiccation, salt and cold causing major changes in plant development and physiology.

Species from different taxonomic groups show similar invasion traits [PDF]
, 2015 Invasion ecology tends to treat taxonomic groups separately. However, given that all invasive species go through the same stages of the invasion process (transport, escape, establishment, spread), it is likely that – across taxa – comparable traits help ...

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 ...

Frontiers in Chemistry, 2019 Sodium oleate (NaOl), a collector in diaspore flotation, has been widely used for more than 30 years, while its low selectivity becomes an issue under today's process requirement. This study introduced tert dodecyl mercaptan (TDM) together with NaOl as a
