Regeneration in gap models: priority issues for studying forest responses to climate change

, 2001
Recruitment algorithms in forest gap models are examined with particular regard to their suitability for simulating forest ecosystem responses to a changing climate. The traditional formulation of recruitment is found limiting in three areas.

Temperature, precipitation and biotic interactions as determinants of tree seedling recruitment across the tree line ecotone [PDF]

, 2017
Seedling recruitment is a critical life history stage for trees, and successful recruitment is tightly linked to both abiotic factors and biotic interactions.

Seedling recruitment least square means.

, 2013
Least square means of seedling recruitment across two shade treatments (shade, no shade), two water treatments (water, control), two gradient locations (mesic, xeric) and four collection periods (spring and fall, 2006 and 2007).

Arthropod invasion disruptsCycas micronesicaseedling recruitment

Communicative & Integrative Biology, 2011
We recently described characteristics of reproductive effort for the cycad Cycas micronesica on the island of Guam. The data were serendipitously recorded just prior to the devastating invasion of the armored scale Aulacaspis yasumatsui. This invasion decimated the cycad population and after six years of infestation no recruitment is occurring among ...

Continental Diversity of Chenopodium album Seedling Recruitment

, 2013
Chenopodium album seedling emergence studies were conducted at nine European and two North American locations comparing local populations with a common population from Denmark. It is hypothesized that C. album seedling recruitment timing and magnitude have adapted to environmental and cropping system practices of a locality. Limitations in the habitat (

Directed endozoochorous dispersal by scavengers facilitate sexual reproduction in otherwise clonal plants at cadaver sites

Ecology and Evolution, 2022
The regeneration niche of many plant species involves spatially and temporally unpredictable disturbances, called recruitment windows of opportunity. However, even species with clear dispersal adaptations such as fleshy berries may not successfully reach

Mycorrhizal Fungi Associated With Juniper and Oak Seedlings Along a Disturbance Gradient in Central Mexico

Frontiers in Forests and Global Change, 2022
Competition for resources between arbuscular mycorrhizal (AM) and ectomycorrhizal (ECM) plants can alter belowground mycorrhizal communities, but few studies have investigated host effects on both AM and ECM communities.

Interspecific associations in seed arrival and seedling recruitment in a Neotropical forest

Ecology, 2016
AbstractContagious seed dispersal refers to the tendency for some sites to receive many dispersed seeds while other sites receive few dispersed seeds. Contagious dispersal can lead to interspecific associations in seed arrival, and this in turn might lead to interspecific associations in seedling recruitment.

Recruitment patterns in four species of Physaria (Brassicaceae): implications for maintenance of population density over time in both native and cultivated stands

Ecología Austral, 2016
Seedling recruitment is a critical stage of a plant’s cycle which determines population viability, the potential for invasiveness of a plant species and the success of establishment of a crop, among other processes.

Seedling recruitment pattern and depth of recruitment of 10 weed species in minimum tillage and no-till seeding systems

, 2006
Differences in periodicity and depth of weed seedling recruitment due to agronomic management practices, such as reduced tillage, have implications for weed competitive ability and management strategies.
