Establishment of new populations is contingent on overcoming abiotic and biotic barriers. While this applies to all species, these hurdles are at the forefront invasion biology where prediction, prevention, eradication, control strategies depend an understanding processes. Terrestrial Arundina graminifolia epiphytic Dendrobium crumenatum two non-indigenous orchids spreading throughout Puerto Ri...

Renanthera imschootiana Rolfe is an extremely rare and endangered tropical epiphytic orchid. Studies on in vitro culture of R. were conducted order to conserve increase the genetic pool this wild orchid species. In study, effect plant growth regulators (BA NAA), ripe bananas combination with potato, humic acid, silver nanoparticles (AgNPs) investigated find a suitable condition for regeneration...

Species of the large family Orchidaceae display a spectacular array of adaptations and rapid speciations that are linked to several innovative features, including specialized pollination syndromes, colonization of epiphytic habitats, and the presence of Crassulacean acid metabolism (CAM), a water-conserving photosynthetic pathway. To better understand the role of CAM and epiphytism in the evolu...

Potential ecophysiological responses to nitrogen deposition, which is considered to be one of the leading causes for global biodiversity loss, were studied for the endangered endemic Mexican epiphytic orchid, Laelia speciosa, via a shadehouse dose-response experiment (doses were 2.5, 5, 10, 20, 40, and 80 kg N ha(-1) yr(-1)) in order to assess the potential risk facing this orchid given impendi...

An efficient in vitro regeneration protocol from seed culture has been established successfully for Dendrobium chrysotoxum, an epiphytic orchid having tremendous ornamental and medicinal values. Seed germination response was encouraging in Mitra (M) medium enriched with different combinations of auxins and cytokinins. Medium supplemented with 0.4% activated charcoal (AC), 2 mg/L 6-benzyl amino ...

Flowering plant density can increase number of visits and fruit set in multi-flowering plants, however this aspect has not been studied on few flower species. We studied the effects of individual floral display and plant density on the fruit production of the epiphytic, moth-pollinated orchid, Ryncholaelia glauca, in an oak forest of Chavarrillo, Veracruz, Mexico. Species is non-autogamous, and...

The destinies of epiphytic orchids (about 70% all orchids) are linked to their host trees. However, there is little information on if differences in trees characteristics can affect the long-term persistence orchid populations, and how this might vary under different climatic conditions. We compared population dynamics two species, Alamania punicea Oncidium brachyandrum growing with contrasting...
