Negative density dependence of seed dispersal and seedling recruitment in a Neotropical palm [PDF]

, 2014
Negative density dependence (NDD) of recruitment is pervasive in tropical tree species. We tested the hypotheses that seed dispersal is NDD, due to intraspecific competition for dispersers, and that this contributes to NDD of recruitment.

Vertebrate herbivory impacts seedling recruitment more than niche partitioning or density-dependent mortality.

, 2022
In tropical forests, resource-based niches and density-dependent mortality are mutually compatible mechanisms that can act simultaneously to limit seedling populations.

Recruitment and mortality of Rhizophora mangle L. seedlings in the Tropical Southwestern Atlantic mangrove [PDF]

Brazilian Journal of Biology
Studies in the long-term recruitment and mortality of mangrove seedlings can help to understand mangrove demography and its relationship with climatic variables, environmental restoration and advances in the ecology of this ecosystem.

Effects of flooding and its temporal variation on seedling recruitment from the soil seed bank of a Neotropical floodplain

Acta Botânica Brasílica
Evaluation of the effects of flooding on seedling recruitment from seed banks helps in understanding vegetation regeneration in floodplains. We studied the effects of simulated flooding on richness and abundance of, and temporal variation in, seedling ...

Recruitment and Patch Establishment by Seed in the Seagrass Posidonia oceanica: Importance and Conservation Implications

Frontiers in Plant Science, 2017
Seagrasses are declining globally, and deeper understanding is needed on the recruitment potential and distribution of new populations for many threatened species to support conservation planning in the face of climate change.

Seed production and recruitment in primary and harvested Nothofagus pumilio forests: Influence of regional climate and years after cuttings

Forest Systems, 2015
Aim of study: Harvesting proposals (e.g. variable retention) for Nothofagus pumilio forests are based on canopy opening, to increase recruitment and enhance seedling growth, by modifying light and soil moisture.

Forest resilience and regeneration dynamics following wildfire disturbance

Ecosphere, 2023
Species that are adapted to specific disturbance regimes may be sensitive to changes such as severity, frequency, and extent of ecosystem perturbation. Along range margins, these sensitivities may be exacerbated by concurrent changes in climate resulting

Seedling Recruitment of Native Tree Species in Active Restoration Forest [PDF]

, 2020
Since the 1970’s, concern has grown over the environmental impact of deforestation over large areas in the northern mountains of Thailand and conversion of forest to agriculture.

Post-fire litter microsites: Safe for seeds, unsafe for seedlings

, 1993
We explore the effect of post—fire microsites on seed and seedling distribution and hence their potential role in community restoration. A summer wildfire and control burn in a sclerophyll shrubland in mediterranean Australia produced mosaics of ...

Facilitative andcompetitive effectsofbrackenfronds and litterontree seedling recruitment

Introduction: Tropical montane forests are diverse ecosystems increasingly threatened by land-use change and frequent uncontrolled fires caused by humans. After these fires, affected areas are often dominated by ferns of the genus Pteridium (bracken), delaying the rate of forest regeneration.
