SEEDLING DEMOGRAPHY OF SWIDA CONTROVERSA: EFFECT OF LIGHT AND DISTANCE TO CONSPECIFICS
Ecology, 2002Some shade-intolerant trees with soil seed banks also have advanced recruits under a closed canopy. To determine the relative roles of advanced recruits and seed banks in regeneration, we studied the demography of seedling cohorts of the deciduous canopy tree, Swida controversa, in an old-growth temperate forest in Japan.

Seedling demography in an alpine ecosystem†
American Journal of Botany, 2003Seedling establishment has long been believed to be rare on alpine tundra because of predicted life history trade‐offs, the clonality of alpine species, and the harshness of the alpine climate. Contrary to the idea that seedlings are rare on alpine tundra, a 4‐yr demographic study of seedlings at Niwot Ridge, Colorado, USA, found seedlings at high ...

Seed Demography and Seedling Survival in a Population of Atriplex triangularis Willd
American Midland Naturalist, 1986Survival of different cohorts of Atriplex triangularis in an inland saline environment was observed. Seedlings developing early in the growing season had a higher probability of surviving to fruit than those from later cohorts. In highly saline habitats no plants survived to maturity. Seed rain in the Atriplex zone averaged 32,902 seeds m2 and the seed

The abiotic and biotic factors causing mortality of Salix lasiolepis (Salicaceae) seedlings were studied along a seasonally flowing stream in northern Arizona. Mortality of first‐year seedlings approached or equaled 100% for the four cohorts observed.

(1) The appearance and survival of Trifolium repens seedlings from naturally deposited seed were monitored for 3 years under different sheep grazing managements and phosphate fertilizer inputs, and in four slope/aspect zones, in summer moist New Zealand hill country.

The effect of management operations on the demography of Eucalyptus globulus seedlings
Forest Ecology and Management, 2019Abstract There has been an increased concern about the invasiveness of Eucalyptus globulus Labill. Much research has been devoted to understanding the factors influencing E. globulus recruitment. Standard management operations, performed inside and outside plantations, cause profound disturbances on soil and vegetation, potentially influence E ...

Seedling bank demography over 11 years in an island laurel forest, Tenerife, Canary Islands
Forest Ecology and Management, 2020Abstract Confined to the humid cloud belt of the Macaronesian Islands the Laurel-forests are sensitive to climate changes. Intense natural disturbances are rare and regeneration includes asexual regeneration and dominance of shade intolerant species in the seedling bank.

Seed and seedling demography of invasive and native trees of subtropical Pacific islands
Journal of Vegetation Science, 2003Abstract. Bischofia javanica is an invasive tree of the Bonin Islands in the western Pacific, Japan. This species has aggressive growth, competitively replacing native trees in the natural forest of the islands. The aim of this study was to examine seed and seedling factors which might confer an advantage to the establishment of Bischofia over native
