Evolution of Seed Dispersal Modes in the Orchidaceae: Has the Vanilla Mystery Been Solved?
Orchid seeds are predominantly wind-dispersed, often developed within dry, dehiscent fruits that typically release millions of dust-like seeds into the air. Animal-mediated seed dispersal is a lesser-known phenomenon in the family and predominantly occurs in groups belonging to early-diverging lineages bearing indehiscent, fleshy fruits with hard, rounded, dark seeds.

Effect of habitat fragmentation on seed dispersal ability of a wind-dispersed annual in an agroecosystem
Deficient dispersal ability due to habitat fragmentation adversely impact demographic connectivity and gene flow among population in a metapopulation, and therefore potentially leads to local extinction. A rich body of theoretical work provides distinct predictions regarding the distribution of dispersal abilities in relation to fragmentation gradient. Yet, empirical data remains...Chen, Si-Chong ; Dener, Efrat ; Altman, Ariel ; Chen, Fang ; Giladi, Itamar

Trade‐off between seed dispersal in space and time.
Seed movement and delayed germination have long been thought to represent alternative risk‐spreading strategies, but current evidence covers limited scales and yields mixed results. Here we present the first global‐scale test of a negative correlation between dispersal and dormancy. The result demonstrates a strong and consistent pattern that species with...Chen, Si‐Chong ; Poschlod, Peter ; Antonelli, Alexandre ; Liu, Udayangani ; Dickie, John B.
