A new technique for stain-marking of seeds with safranine to track seed dispersal and seed bank dynamics

Accurate monitoring of seed dispersal is essential for understanding gene flow and seed bank dynamics, as well as predicting population distributions and dissemination. Here we introduce a new seed-tracking technique by safranine stain seeds/fruits by immersing or spraying with staining solution. The staining of seeds in Safranine was not found to have an effect on seed weight or germination ability, regardless of whether the seeds were stained ex situ or in situ. The magenta color of stained seeds remained recognizable for more than 5 months after seeds were buried in soil for 44 of 48 species. In arable land and in disturbed and natural terrestrial or hydrophytic ecological ecosystems, this technique can be widely used to staining most of the seed plant species and the investigation of seed dispersal.

Stone Age hunter-gatherer ceramics of North-Eastern Europe: new insights into the dispersal of an essential innovation

Time-tested trajectories in early ceramics history are revived by combining existing knowledge with the results of extensive statistical evaluation of 17 selected early ceramic complexes with total 535 vessel units from Finland, Estonia, Lithuania, and Russia. As a result, three distinct lines of early pottery development are thought to have played a role in the origins of early ceramic groups east and north of the Baltic Sea.

The effect of interplays among climate change, land-use change, and dispersal capacity on plant redistribution

The range shifts of plants are a result of dynamic interactions among climate change, land-use change, and dispersal capacity. Our research sought to investigate the vital roles of climate change, land use change, and dispersal ability in five warm-adapted evergreen broadleaved plants, namely, Pittosporum tobira, Raphiolepis indica var. Four dispersal scenarios, including dispersal, short-distance dispersal, and full dispersal of five species under two climate change scenarios, realistic habitat pathways 4. 5 and 8. 5, were included in this report, including dispersal, no dispersal, long-distance dispersal, and four dispersal scenarios. Climate change and land-use change were, on average, more influential than dispersal capacity in plant range dynamics, as shown by this article. However, the determining power of those factors was species-specific, demonstrating the strong influence of dispersal capacity on the future range of P. to Bira.

Implications of habitat‐driven survival and dispersal on recruitment in a spatially structured piping plover population

We estimated hatchu2010year reproduction to adulthood and natal dispersal rates among two breeding groups of Northern Great Plains piping plovers from four cohorts. The natal dispersal rates increased when more vegetation was available at the natal site this year than in the previous year. Overall, unbalanced, high natal dispersal rates within the Northern Great Plains indicate high connectivity among multiple regions with different watersheds along the Missouri River and in the United States Alkali Wetlands, owing to fluctuating habitat availability, particularly in the Midwest. Our findings indicate that plovers in the Northern Great Plains take advantage of highly populated habitats in a wide geographic area rather than a true metapopulation, but further study on adult breeding dispersal is needed to establish population structure.

Large‐scale PVA modeling of insects in cultivated grasslands: The role of dispersal in mitigating the effects of management schedules under climate change

Dispersal was included in the HiLEG software, which we previously developed to investigate the relationship between climate change and agricultural land use in single populations. The model was developed for the large marsh grasshopper in North Germany's cultivated grasslands to assess species growth and dispersal success, depending on the severity of climate change in subregions, the additional effect of grassland covers on dispersal success, and the role of dispersal in compensating for defunct grassland mowing. The LMG could thrive and expand purely due to climate change alone, but grassland cover was a minor factor. More widespread climate change could encourage LMG expansion to uninhabited regions, but it would necessitates specific mowing schedules along the route.

Environmental filtering rather than dispersal limitation dominated plant community assembly in the Zoige Plateau

Abstract : The discovery of plant communities under the leadership of plant communities is vital to plant conservation in terrestrial habitats. In alpine meadows, it is not commonly measured or quantified how much deterministic versus stochastic processes contribute to community assembly. In the Zoige Plateau, we measured community similarity with spatial and geographic distance. In addition, we used redundancy analysis to divide the differences in the relative abundance of plant families into four categories to determine the effects of environmental and spatial. The assemblage similarity liner in Species slowed with geographic distance, but it decreased dramatically as distance from total phosphorus, alkali nitrogen, and ammonia nitrogen decreased significantly as the distance between species assemblage similarity liner decreased with increasing distance. Our research reveals the process of plant community assembly in the alpine ecosystem, in which environmental filtering plays a more vital role than dispersal limitation.

Effects of spatial distance and woody plant cover on beta diversity point to dispersal limitation as a driver of community assembly during postfire succession in a Mediterranean shrubland

In Central Spain, we analyzed the distribution of beta diversity and its components in a herbaceous plant community following fire and in relation to dispersal capability. During the first three years after wildfire, multiple sites in the United Kingdom were analyzed by multiple-u2010site beta diversity and its key traits of turnover and nestedness of all herbaceous plants, or grouped by dispersal syndrome. We investigated the correlation between pairwise beta diversity, the component's, and geographic distance or differences in woody plant cover, a measure of biotic interactions. Multiple u2010site beta diversity was dominated by turnover, which was shown by high multiple u2010site beta diversity. Species with less dispersal capabilities had a longer spatial pattern of dissimilarity, which was evident in the case of dissimilarity in the region. Also for species with high dispersal ability, these results show that dispersal limitation reigns over biotic interactions with woody plants as a source of local community assembly.
