Recruitment of ponderosa pine seedlings in the Cascade Range

Forest Ecology and Management, 2009
Abstract Abiotic stresses on seedling regeneration in xeric ecosystems are great, hence recruitment processes can be facilitated by stand factors that ameliorate the germinant-scale microenvironment. An experiment was conducted on the eastern slope of the Cascade Range to test the effects of shrub cover, simulated seed caching, and substrate on the ...

Seedling recruitment in the perennial herb Lathyrus vernus

Flora, 1996
Summary Seedling recruitment in the low-fecund perennial herb Lathyrus vernus was investigated during 4 years in 11 patches. Emergence and seedling survival were studied in unmanipulated quadrates and in quadrates where additional seeds had been sown. Experimental addition of seeds increased both the proportion of quadrates with recruitment and the

Development and testing of a mechanistic potential niche model of riparian tree seedling recruitment [PDF]

Ecological Modelling
Seedling recruitment is an important reproductive process for sustaining riparian tree populations in arid and semi-arid environments. Riparian tree species such as cottonwoods and willows are highly adapted to the dynamic riparian environment; their ...

Competition and Facilitation in the Recruitment of Seedlings in Patagonian Steppe

Functional Ecology, 1992
The Patagonian steppe consists of shrubs encircled by relatively dense stands of grasses; the areas between shrubs have scattered tussocks, interspersed with bare soil. This study investigates the seed bank and the establishment of a perennial grass, Bromus pictus, around shrubs and in the scattered-tussock patches, with special attention to root ...

Birds and neotropical mistletoes: effects on seedling recruitment

Oecologia, 1983
Two groups of neotropical mistletoes differ in fruit structure and consequently in the manner their seeds are deposited by avian frugivores. Birds defecate seeds of one group in clumps, but deposit seeds of the other group singly by regurgitation. A significant proportion of adult plants of both species were found growing alone, indicating a higher ...

Manchurian ash seed bank and seedling recruitment

Journal of Northeast Forestry University, 1991
To understand the natural regeneration of manchurian ash and the seed banks under various secondary stands, we have investigated the seed quantity and vitality of major trees in the ground floor of the stands. In natural secondary stands and dahurian larch plantations with seed source of manchurian ash around them, the vital seed numbers of valuable ...

Seedling Recruitment in Forests: Calibrating Models to Predict Patterns of Tree Seedling Dispersion

Ecology, 1994
Recruitment, the addition of new individuals into a community, is an important factor that can substantially affect community composition and dynamics. We present a method for calibrating spatial models of plant recruitment that does not require identifying the specific parent of each recruit.

Riparian vegetation model to predict seedling recruitment and restoration alternatives

Journal of Environmental Management, 2020
Native riparian vegetation communities have declined downstream of large water infrastructure like dams and diversions, owing to water management operations that prevent successful seedling colonization and recruitment. Altered timing and magnitude of reservoir releases to fulfill competing water demands often lead to reduced peak discharges and flow ...

Review: Microsite characteristics influencing weed seedling recruitment and implications for recruitment modeling

Canadian Journal of Plant Science, 2012
Bullied, W. J., Van Acker, R. C. and Bullock, P. R. 2012. Review: Microsite characteristics influencing weed seedling recruitment and implications for recruitment modeling. Can. J. Plant Sci. 92: 627–650. A weed seedling recruitment microsite is the location of a weed seed in the soil profile which affects germination, time of emergence and seedling ...

Seedling Recruitment Strategies in Obligate‐Seeding and Resprouting Banksia Shrubs

Ecology, 1987
Banksia ericifolia is killed by fire and so depends upon seeds for persistence. In contrast, B. oblongifolia can persist after fire by resprouting from protected buds, as well as by recruiting seedlings. These serotinous species coexist in the fire—prone scrublands of the Sydney Basin.
