田间观察和实验表明，高密度幼苗的存在抑制了随后的沙漠一年生植物的萌发。由于高密度生长的植物面临着对有限资源的激烈竞争，种子的这种反应被解释为一种适应，以避免不利的竞争环境，那里的生长和生存可能很低。
SummaryField observations and experiments indicate that the presence of seedlings at high densities inhibits subsequent germination of desert annuals. Since plants growing at high densities face severe competition for limited resources, this response by seeds is interpreted as an adaptation to avoid an unfavorable competitive climate where growth and survivorship are likely to be low.
