, 2008 Orchids is an intrusion detection tool based on techniques for fast, on-line model-checking. Orchids detects complex, correlated strands of events with very low overhead in practice, although its detection algorithm has worst-case exponential time complexity. The purpose of this paper is twofold.

Biogeography of Orchid Mycorrhizas
2017Most orchid mycorrhizal fungi (OMF) are free-living decomposers that do not depend on orchids for establishment or survival. Despite their importance for completion of the orchid life cycle, the geographical distribution of OMF remains poorly understood.

The present contribution is devoted mainly to a revision of the species of Angraecum occurring on the mainland of Africa, including seven species described here for the first time. There are also descriptions of three new species belonging to other genera of Angraecoid orchids as well as a treatment of some of the species of Eulophia allied to E ...

Orchid seed sensitivity to nitrate reflects habitat preferences and soil nitrate content.
Plant biology, 2019Orchids are distributed around the world, however, the factors shaping their specific distribution and habitat preferences are largely unknown. Moreover, many orchids are at risk for becoming threatened as landscapes change, sometimes declining without ...

This chapter will deal with methods of clonal propagation for members of the two major morphological groups of orchids. The first group, sympodials, includes such genera as Cymbidium, Cattleya, Dendrobium, and Oncidium. They are characterized by a multi-branchingrhizome that can supply an abundance of axillary shoots for use as explants.

Following the treatment of the orchid flora of Thailand in the series “Orchid Genera in Thailand” and the recent paper by G. Seidenfaden & J. J. Wood 1992 on “The Orchids of Peninsular Malaysia and Singapore”, the present paper aims at filling the gap in our knowledge of the orchids of the Southeastasiatic mainland by compiling a survey of the ...

ORCHID BEES DON'T NEED ORCHIDS: EVIDENCE FROM THE NATURALIZATION OF AN ORCHID BEE IN FLORIDA
Ecology, 2006Almost 200 species of orchid bees are the exclusive pollinators of nearly 700 specialized orchids in the neotropics. This well-known mutualism involves orchids, called perfume orchids, which produce species-specific blends of floral fragrances, and male orchid bees, which collect and use these fragrance compounds during their courtship.

Microbiota of the Orchid Rhizoplane
Microbiology, 2001Six bacterial strains isolated from the underground roots of the terrestrial orchid Calanthe vestita var. rubrooculata were found to belong to the genera Arthrobacter, Bacillus, Mycobacterium, and Pseudomonas. Strains isolated from the aerial roots of the epiphytic orchid Dendrobium moschatum were classified into the genera Bacillus, Curtobacterium ...
