The Regeneration Niche in Bottomland Hardwood Forests: Tree and Herbaceous Communities Along Interacting Gradients of Flood and Light in East Texas Floodplains
… in this document characterizes environmental niches of bottomland hardwood (BLH) plant species, focusing on how gradients in light availability and flooding shape understory composition and exploring a potential trade-off between shade and flood tolerance. Field surveys demonstrated that small …

Seed and seedling ecology of four Agulhas Proteaceae
… reciprocal transplants were used to test whether regeneration niche requirements were determinants of adult distributions. There were no germination niche differences, but limestone species showed greater seedling mortality on the transplanted colluvial sands than limestone. There were also …

Persistence potential of Great Basin high-elevation conifers under novel climates and disturbance regimes
… novel conditions or migrate to track ecological niches. Contemporary climate change outpaces the adaptive capacity of long-lived, geographically isolated tree species, therefore differential regeneration success and proactive management will shape the future composition and distribution of …

Ecological significance of seed traits in the genus Macaranga
According to the regeneration niche hypothesis, the transition from seeds to seedlings is critical in determining plant distribution patterns. This initial stage of recruitment may be strongly influenced by seed mass via effects on the sensitivity to light quality and soil moisture availability for …

Fate of Eucalyptus marginata seed from canopy-store to emergence in the northern jarrah forests of Western Australia: Research to help improve regeneration following shelterwood treatment
The establishment of seedling regeneration is a key process in and indicator of ecologically sustainable forest management. The availability of seed and the creation of a suitable seedbed are recognised as important factors limiting seedling recruitment. A silvicultural method commonly used across …

Revisiting Aloe dichotoma’s suitability as an indictor of climate change in southern Africa
… (and longitudinal) range, a greater focus on the regeneration niche and physiological thresholds would help advance our understanding of A. dichotoma’s susceptibility to moisture and temperature deficits arising from climate change. Assessment of the suitability of A. dichotoma as a sentinel of …
