Language Label … Webb31 mars 2024 · Abstract. Ants are abundant, diverse, and occupy nearly all habitats and regions of the world. Previous work has demonstrated that ant diversification coincided with the rise of the angiosperms, and that several plant traits evolved as ants began to expand their nesting and foraging habits. In this study, we investigate whether …

Webb6 apr. 2024 · 1.Introduction. Angiosperms exhibit a great diversity of inflorescence types, such as racemes, panicles, corymbs, and cymes, depending on the number and arrangement of flowers on shoots, and their branching patterns (Benlloch et al., 2007; Endress, 2010).The evolution of inflorescences has attracted the interest of botanists for … WebbAngiosperms are a relatively recent evolutionary innovation, but their genome sizes have diversified remarkably since their origin, at a rate beyond that of most other taxa. Genome size is often correlated with plant growth and ecology, and extremely large genomes may be limited both ecologically and evolutionarily.
