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.

Response of Grain Yield and Yield Components of Triticale to Sowing Date and Plant Density [PDF]
Journal of Agricultural Science and Sustainable Production, 2013 In order to study of sowing date and plant density on Triticale (Tritico secale), a field experiment was carried out under dry farming in the Rice Research Institute of Iran, during 2008-2009.

Herbaceous Filter Strips in Agroecosystems: Implications for Ground Beetle (Coleoptera: Carabidae) Conservation and Invertebrate Weed Seed Predation [PDF]
, 2018 A 9.3-ha crop field flanked by two filter strips was selected to: 1) assess carabid beetle activity-density and community composition and 2) assess post-dispersal weed seed predation by invertebrates in these habitats.

Global patterns of potential future plant diversity hidden in soil seed banks
Nature Communications, 2021 Soil seed banks represent a critical but hidden stock for potential future plant diversity on Earth. Here we compiled and analyzed a global dataset consisting of 15,698 records of species diversity and density for soil seed banks in natural plant ...

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

Seeding Density Directly Influences Crambe Productivity
Revista de Gestão Social e AmbientalObjective: The objective of this study was to evaluate the development and production characteristics of crambe, under different planting densities and different spacing between rows. Theoretical Framework: For crops that are still little explored, such as crambe, sowing management in new regions lacks information that would enable rural producers to
