Plant size and intraspecific variability in vascular epiphytes
… the prevalent, but barely tested notion of epiphytes as inherently slow growing plants and simultaneously illustrates the profound resource limitations that epiphytes are subjected to in the canopy of a seasonal rain forest. From habitat conditions it seems that size-related differences in …

The influence of epiphytes on arthropods in the tropical forest canopy
… challenge for modern biology. In this context, epiphytes are presumed to play an important role. To investigate the biological reality of this persistent yet insufficiently investigated notion, I conducted the present study. The main questions I intended to clarify were: (1) do epiphytes affect …

Assessing biofilm and epiphytes on seagrass leaves as bioindicators of environmental change
… limited studies within seagrass habitats. Algal epiphytes within seagrass meadows are frequently studied and are considered good bioindicators of light limitation, however, faunal epiphytes have rarely been considered. The objective of this research was to determine the effect of two different …

Exploring Interactions of Phyllosphere Epiphytes with Plant Pathogenic Bacteria Pseudomonas and Xanthomonas on Tomato
<p>Recent studies have indicated the importance of resident microflora of plants in contributing towards overall plant health. Among difference components of the plant microbiome, <em>Methylobacterium</em> and <em>Sphingomonas</em> have been recognized as common residents of the …

Distribution and biomass of epiphytic seaweeds on the kelp Ecklonia maxima (Osbeck) Papenfuss, and the potential effects of two kelp-harvesting methods in the Western Cape
… the Cape Peninsula. The distribution of the epiphytes on the different portions (stipe; primary blade and first 30cm of secondary blades; rest of the secondary blades) of kelp was investigated. E.maxima was sampled at five sites around the Cape Peninsula, and the epiphytes on each portion …

Assessing Feeding Preferences and Spatial Patterns of Lagodon rhomboides Linnaeus
… (<em>Thalassia testudinum</em>) and algal epiphytes. St. Joseph Bay, FL was also surveyed to determine areas within this ecosystem that could be highly impacted by pinfish abundance. Significant spatial patterns were found among pinfish, as well as urchins and invertebrates, suggesting that …

Ecological and biogeographical studies on the rocky shore seagrass Thalassodendron ciliatum (Forsskal) den Hartog and its seaweed epiphytes at the southern limit of its distribution in the western Indian Ocean by Catherine Margot Browne.
… ciliatum and its associated macroalgal epiphytes. Seagrass populations were sampled at Jesser Point (Sodwana Bay) and at Maphelane, the former being larger and the southernmost populations observed, and the latter being the site of an isolated small population further south.

A study of the distribution of algae in the Two Oceans Aquarium, Kelp Tank, Cape Town
… tank. The seaweeds were brought in as either epiphytes on mature macro algae or as epiphytes on boulders that were placed on the floor of the tank. Thus, the community in the tank can be assumed to have established itself naturally. This study looked at the extent of the species diversity, …

Comparisons of habitat use and diet of herbivorous kyphosids (Genus Kyphosus) in tropical and temperate reefs
… kelp and Sargassum than adults and more green epiphytes (e.g. Derbesia sp.) and red algae (Hypnea sp.). Conversely, the diet of K. cornelii consisted almost entirely of red and green epiphytes, such as Hypnea sp. (30-33%) and Ulva sp. (15- 31%) at both life stages. These results indicate that …

The investigation of bacterial pathogens of the red macroalga gracilaria gracilis and its response to bacterial infection
… A large number of culturable bacterial epiphytes isolated from G. gracilis from Saldanha Bay, South Africa, and Luderitz, Namibia were characterised and compared. The number of culturable bacteria isolated from the seawater surrounding the macroalgae was significantly lower than that …

MOVEMENTS, ACTIVITY RANGE, HABITAT USE, AND CONSERVATION OF THE JAMAICAN (YELLOW) BOA, EPICRATES SUBFLAVUS
… DBH are key features of boa habitats. Vines and epiphytes provide resting places, camouflage, and travel routes for boas. Conservation of the Jamaican boa must include an extensive education and outreach program to dispel myths about the boa and increase local peoples’ knowledge of and attitudes …

Cultivation of Palmaria palmata: spore release, vegetative propagation and decontamination techniques.
… of year as the biomass was heavily fouled with epiphytes. There is potential for this species to be grown commercially if further research takes place to overcome the persisting problems described in this thesis.

Biological wastes as plant growth substrate amendments
… but no attempt is made to differentiate between epiphytes and endophytes. Results here indicate that the mode isolates persist endophytically thereby escaping conventional chlorine washes and they may also induce host defenses, which results in their suppression and in negative results in …

Trophic dynamics in Australian seagrass beds : unravelling linkages from nutrients to fish
… trophic levels. Short-term experiments involving epiphytes, grazers and juvenile fish that manipulated nutrient levels and predation rates often behaved in ways that contradicted the patterns described above for long-term studies. In particular, manipulative studies showed strong evidence for …

Molecular Characterization of Spinach (Spinacia Oleracea) Microbial Community Structure and its Interaction With Escherichia coli O157:H7 in Modified Atmosphere Conditions
… In contrast growth enhancement produced by epiphytes was associated to low correlations in carbon source utilization and the ability of E. coli O157:H7 to rapidly utilize carbon resources. In packaged spinach, E. coli O157:H7 altered the composition of the bacterial community and its growth …
