Episodic Recruitment and Climate Analysis of Ponderosa Pine on the Palmer Divide, Eastern Colorado
<p>Previous recruitment studies on populations of ponderosa pine (<em>Pinus ponderosa</em> P. & C. Lawson) in Colorado have been limited to the western mountains and the Front Range. In this research I used tree-ring data to reconstruct recruitment for ponderosa pine near the eastern limits of its …

A simulated history of Aloe dichotoma recruitment and its link to rainfall : insights from an isolated population near Kenhardt
… dichotoma populations differ in their rates of recruitment and mortality across the species distribution in South Western Africa. Little is known about how recruitment and mortality rates are affected by local climate and ecological factors. Using repeat photography and a statistical recruitment …

Substrate dependant survivorship of Ecklonia maxima, in southern African kelp communities
… Establishment on rock may occur through episodic recruitment escaping grazing pressure. In areas with low grazing intensity, recovery from catastrophic storms may be limited by competition with understorey algae.

The dynamics of the Afromontane forest remnants in the Southwestern Cape
… scree fynbos areas at Orange Kloof suggests an episodic recruitment strategy which is influenced by local species composition and seed production.

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
… as important factors limiting seedling recruitment. A silvicultural method commonly used across northern and eastern jarrah forest blocks is shelterwood cutting. The primary objective of treating jarrah forest to shelterwood is to promote seedling regeneration in areas lacking sufficient …

Life history traits of South African Encephalartos spp. (Zamiaceae) and their implications for understanding population structure, responses to threats and effective conservation action
… structure is valuable for determining whether recruitment in a population is adequate for species survival. Static life tables and Chi-Squared analyses were used to test differences in the population structure and survivorship patterns of species between and within the life history groups. If …
