Mangrove understorey absence: a consequence of evolution?
Journal of Tropical Ecology, 1988Recent communications in this Journal (Corlett 1986, Janzen 1985, and Lugo 1986) require some clarification and a search for a more tractable hypothesis to explain the common absence of a mangrove understorey. For ad hoc discussion purposes we define a mangrove understorey species as a plant species that reaches maturity and reproduces beneath the ...

CONTROL OF THE UNDERSTOREY IN WET EUCALYPT FORESTS
Australian Forestry, 1965SUMMARY The dense understoreys found in forests in areas of high rainfall in Tasmania are described. Present practices of logging and burning for regeneration are causing increases in the area covered by understoreys of wet sclerophyll scrub at the expense of rain-forest understoreys.

Understorey vegetation change in a Picea mariana chronosequence
Vegetatio, 1988Eighteen black spruce (Picea mariana) stands, representing postfire ages of 26 to 120 yr, were surveyed for understorey vegetation and site/microsite characteristics at two spatial scales. This enabled comparison of within- versus among-stand compositional variation.

Response of understorey vegetation to heavy metal loading
2000Many heavy metals such as manganese, zinc, copper, iron and molybdenum are essential micronutrients for plants, but are toxic at higher concentrations and disturb most of their primary physiological processes. This results in growth retardation and root damage (Tyler et al. 1989).

Sunflecks and Their Importance to Forest Understorey Plants
1988Publisher Summary This chapter begins with an introduction on the topic, that is, sunflecks and their importance to forest understorey plants. Sunflecks occur when predominantly direct-beam radiation passes through openings in the forest canopy. Measurement of sunfleck activity beneath forest canopies through various techniques namely, area-survey ...

LODGING OF SOYBEAN GENOTYPES IN UNDERSTOREY OF COCONUT PLANTATIONS
Madras Agricultural Journal, 1994Experiments were simultaneously conducted at the Tamil Nadu Agricultural University, Coimbatore with fifteen soybean genotypes in three environments to study the lodging pattern and to identify the lodging resistance or susceptability of soybean genotypes for appropriate use in various cropping systems. Soybean plants lodged severely within two coconut

Facilitation in an unproductive boreal forest understorey community
Journal of Vegetation Science, 2010Questions: We tested the hypothesis that if competition had a significant influence in structuring this boreal plant community, removal of neighbours, addition of fertilizer and addition of water would all benefit the transplanted seedlings. Alternatively, if facilitation had a greater influence, then removal of neighbours would be detrimental to the ...

The complexity of forest borders determines the understorey vegetation
Applied Vegetation Science, 2017AbstractQuestionsWhat are the most important drivers of plant species richness (gamma‐diversity) and species turnover (beta‐diversity) in the field layer of a forest edge? Does the tree and shrub species richness structure and complexity affect the richness of forest and grassland specialist species?LocationSoutheast Sweden.MethodsWe sampled 50 forest ...

Nitrogen storage forms in nine boreal understorey plant species
Oecologia, 1997Storage forms of N were studied in below-ground structures of nine boreal forest understorey plants. The ericaceous shrubs Vacciniumvitis-idaea and V.myrtillus, the fern Gymnocarpium dryopteris, the grass Deschampsia flexuosa, and the herbs Epilobium angustifolium, Maianthemum bifolium, Solidago virgaurea, Geranium sylvaticum and Trientalis europaea ...
