Impact of the quality of organic amendments on size and composition of the weed seed bank [PDF]
, 2011 In addition to improving the soil quality, organic amendments of soils may affect weed seed survival, emergence, growth and reproduction. This study evaluated the effects of applications of different qualities of organic amendments on size and ...

Testing mechanisms of compensatory fitness of dioecy in a cosexual world [PDF]
, 2019 Questions: All else being equal, populations of dioecious species with a 50:50 sex ratio have only half the effective reproductive population size of bisexual species of equal abundance. Consequently, there is a need to explain how dioecious and bisexual

Effects of Seed Size and Cache Density on the Seed Fate of Quercus wutaishanica Mediated by Rodents
LifeAnimal-mediated seed dispersal is very important for plant population regeneration and the stability of forest ecosystems. Seed size and cache density are important factors for seed dispersal, but we still know little about seed size selection at ...

Seeding density in wheat: the more, the merrier? [PDF]
Scientia Agricola, 2013 Adjustment of seeding schemes is one of the crop management techniques that most influences grain yield components. This work aimed to characterize the potential grain yield and its components in wheat (Triticum aestivum L.) genotypes with contrasting tillering ability under different seeding densities and environments.

Markedly Divergent Tree Assemblage Responses to Tropical Forest Loss and Fragmentation across a Strong Seasonality Gradient [PDF]
, 2015 We examine the effects of forest fragmentation on the structure and composition of tree assemblages within three seasonal and aseasonal forest types of southern Brazil, including evergreen, Araucaria, and deciduous forests.

Tree density-dependence effects on seed dispersal of a large-seeded tropical tree
Journal of Tropical Ecology, 2023 Abstract One of the biggest issues in plant ecology is determining the interaction outcome between seeds and scatter-hoarding rodents because the latter has a dual role as dispersers and predators of seeds. Density-dependence contexts involving resource abundance largely influence the outcome of this interaction.
