The coupling of recruitment and disturbance by fire in two resprouting Proteaceae species

Abstract: Recruitment in plant populations is often tightly coupled to major disturbances such as fires. For species with persistent seed banks, fire-related cues may allow or enhance germination. The litter layer influences germination and may modify the impact of seed predators on seeds and seedlings. The litter layer is obviously affected by fire, providing one mechanism by which disturbance can determine recruitment. We tested the role of litter in the disturbance-recruitment coupling of two species with contrasting… Show more

“…For example, as mentioned earlier, low dormancy thresholds could reduce bet-hedging ability by exhausting the seed bank. While serotinous species generally commit all seeds to the one fire event (Keeley et al 2011), this strategy is often offset by seeds much larger in size than soil seed bank species (e.g., those from the genus Banksia or postfire flowering species such as Telopea speciosissima; Denham et al 2011) Lamont 1985; Whelan and Brown 1998). There was some support that facultative species in our study spread germination over a slightly longer time period than the obligate species, which could be indicative of some bet-hedging capability.…”

“…Seed size is also important for emergence as a high-intensity fire can kill seeds at shallow depths ( Bond et al, 1999 ) and larger seeds may have an advantage as they are more capable of germinating successfully from deeper within the soil ( Liyanage and Ooi, 2017a ). Favourable conditions for seedling establishment tend to be short-lived in fire-prone systems and seeds with faster germination rates and faster seedling growth rates, leading to bigger seedlings at any given time, can have an advantage in capturing the increased availability of resources, such as light, space and nutrients ( Moles and Westoby, 2004a ; Denham et al, 2011 ). Factors, such as ploidy and range size, that can be related to traits during early life history stages may have important, perhaps interacting, impacts on regeneration and performance in fire-prone systems.…”
