Recruitment of Seedlings and Vegetative Sprouts in Unburned Chaparral
Ecology, 1992Age structure of 12 stands of chaparral, unburned for 56—120 yr, was investigated. All shrubs produced discernible growth rings, and ring counts on stems from stands of known age, plus synchrony in annual growth ring width among species in the same stand, were taken as evidence that growth rings represented annual rings.

Effects of resource availability on seedling recruitment in a fire-maintained savanna
Oecologia, 2009The herbaceous ground cover of the longleaf pine ecosystem harbors the highest plant species richness in North America, with up to 50 species per square meter, but the mechanisms that regulate this diversity are not well understood. In this system, variability in seedling recruitment events may best explain the extremely high small-scale species ...

Episodic recruitment of the seedling banks in balsam fir and white spruce
American Journal of Botany, 2012• Premise of the study: In ecosystems where seed production is low and masting years are sporadic, or with species that have short‐lived seeds, regeneration is assured by seedling banks rather than seed banks. Seedling establishment and survival play a critical role in determining the composition of these plant communities by supplying new individuals ...

Defaunation and habitat disturbance interact synergistically to alter seedling recruitment
Ecological Applications, 2017AbstractVertebrate granivores destroy plant seeds, but whether animal‐induced seed mortality alters plant recruitment varies with habitat context, seed traits, and among granivore species. An incomplete understanding of seed predation makes it difficult to predict how widespread extirpations of vertebrate granivores in tropical forests might affect ...

Facilitation of Conspecific Seedling Recruitment and Shifts in Temperate Savanna Ecotones
Ecological Monographs, 1999In contrast to documented increases in woody plant dominance of savannas and grasslands of North America, oak (Quercus L.) savannas that form lower tree lines in the southwestern United States and northwestern Mexico have been stable over the last several centuries.

Comparative ecology of seedling recruitment in an oligotrophic wet meadow
Journal of Vegetation Science, 1999Abstract. For the regeneration niche to contribute to the maintenance of species diversity interspecific differences in sensitivity of seedling recruitment to environmental conditions is assumed. We experimentally tested differences between meadow species for the response of seed germination to chilling, and sensitivity of seedling recruitment to ...

Seedling recruitment failure following dipterocarp mast fruiting
Journal of Tropical Ecology, 2004Many rain-forest trees in South-East Asia, including the dominant canopy family Dipterocarpaceae, reproduce in gregarious mast-fruiting events once every 2–11 y (Ashton et al. 1988). The dominant hypothesis for the evolution of masting is that predators are incapable of consuming mast seed crops, so that natural selection has favoured parent trees that

Postfire seedling recruitment at the southern limit of lichen woodland
Canadian Journal of Forest Research, 2009Although fire is the primary mechanism driving regeneration in open black spruce ( Picea mariana (Mill.) BSP) lichen woodland, there are limited data concerning the sources of seedling mortality across the range of burn severity. We monitored planted seedlings in areas of high and low burn severity in Terra Nova National Park (Newfoundland, Canada) to

Seedling recruitment patterns in a tropical dry forest in Ghana
Journal of Vegetation Science, 1992. Studies of seedling demography and dynamics were carried out in a dry forest at Pinkwae, Ghana (rainfall 1100 mm). Seedlings of tree and liana species in permanent transects were tagged, identified, measured and recensused at bimonthly intervals.

Herbivores, seed banks and seedling recruitment in mesic grassland
Journal of Ecology, 19991 An experiment was carried out in a species‐poor acid grassland to determine the effect of insect, mollusc and rabbit herbivory on the size and composition of the seed bank and on seedling recruitment from the seed bank and seed rain. From 1991 to 1997, insects and molluscs were excluded with pesticides, and rabbits with fences.
