| interactions between a sap beetle, sabal palm, scale insect, filamentous fungi and yeast, with discovery of potential antifungal compounds. | the multi-trophic relationship between insects, yeast, and filamentous fungi is reported on sabal palm (sabal palmetto (walter) lodd. ex schult. & schult. f.). gut content analyses and observations of adult and larval feeding of the sap beetle brachypeplus glaber leconte indicate that niche partitioning of fungal food substrata occurs between adults and larvae. this is the first report of specific mycophagous niche partitioning among beetle life stages based on gut content analyses. fungi isolat ... | 2014 | 24586669 |
| teratorhabditis palmarum n. sp. (nemata: rhabditidae): an associate of rhynchophorus palmarum and r. cruentatus. | teratorhabditis palmarum n. sp., an associate of the palm weevils rhynchophorus palmarum and r. cruentatus is described. teratorhabditis palmarum was isolated from newly emerged adults and cocoons of r. palmarum from red-ring diseased coconut palms, cocos nucifera, in trinidad and ecuador, and from red-ring diseased oil palms, elaeis guineensis, in colombia. teratorhabditis palmarum was also associated internally with newly emerged adults of r. cruentatus from mature transplanted cabbage palmett ... | 1990 | 19287730 |
| host response of ornamental palms to rotylenchulus reniformis. | the responses of 20 species of ornamental palms and one cycad (cycas revoluta) to two populations of the reniform nematode, rotylenchulus reniformis, from southern florida were studied in two greenhouse experiments conducted in 1989-1991 and 1991-92. ornamental palms in pots were exposed to initial population densities of 400 and 1,500 r. reniformis/l00 cm(3) soil for 16 and 15 months, respectively. nematode reproduction occurred on acoelorrhaphe wrightii and washingtonia robusta, but not on the ... | 1994 | 19279956 |
| oral rabies vaccine contact by raccoons and nontarget species in a field trial in florida. | rabies is enzootic in raccoons (procyon lotor) in the eastern united states. oral vaccination of free-ranging raccoons against rabies has the potential to control the disease in a principal reservoir and reduce the risk of rabies exposure among domestic animals and humans. free-ranging animal contact with baits containing a vaccinia virus recombinant vaccine expressing the rabies glycoprotein gene (v-rg) was monitored in pinellas county (florida, usa) from february through may 1997. bait contact ... | 1999 | 10574527 |
| the roles of seedling salt tolerance and resprouting in forest zonation on thewest coast of florida, usa. | to determine whether the zonation of seven coastal tree species in north florida correlated with the relative abilities of their seedlings to tolerate soil salinity, we subjected seedlings of sabal palmetto, juniperus virginiana var. silicicola, quercus virginiana, celtis laevigata, ulmus spp., acer floridanum, and liquidambar styraciflua to a range of salinities (ôê+0, 2, 4, 8, 15, and 22 g synthetic sea salt/l; up to 63% full strength seawater salinity) in a 6-mo greenhouse experiment. pots wi ... | 1998 | 21680335 |
| laboratory and field evidence for maleproduced aggregation pheromone inrhynchophorus cruentatus (f.) (coleoptera: curculionidae). | laboratory and field assays were conducted to determine if palmetto weevil,rhynchophorus cruentatus (f.), adults produce an aggregation pheromone. attraction of females in a y-tube olfactometer to conspecific males was greater than to clean air. male and female attraction to conspecific male volatiles combined with host-palm,sabal palmetto (walter), volatiles was greater than to host-palm volatiles alone. similarly, more weevils were caught in the field in traps baited with conspecific males plu ... | 1993 | 24249137 |
| aggregation pheromone of palmetto weevil,rhynchophorus cruentatus (f.) (coleoptera: curculionidae). | 5-methyl-4-octanol is the major aggregation pheromone of the palmetto weevil,rhynchophorus cruentatus (f.). the pheromone (cruentol) was identified by coupled gas chromatographic-electroantennographic (gc-ead) analysis of male-produced volatiles, coupled gc-mass spectrometry (ms) in electron impact and chemical ionization mode, and coupled gc-high resolution ms. in laboratory and field assays, a diastereomeric mixture of synthetic cruentol greatly enhanced attraction of weevils to cabbage palmet ... | 1994 | 24242107 |
| effects of salinity and flooding on seedlings of cabbage palm (sabal palmetto). | sabal palmetto (walt.) lodd. ex schultes (cabbage palm) dominates the coastal limit of many forests in north florida and georgia, united states. changes in saltwater flooding due to sea level rise have been credicted with pushing the coastal limit of cabbage palms inland, eliminating regeneration before causing death of mature trees. localized freshwater discharge along the coast causes different forest stands to experience tidal flooding with waters that differ in salinity. to elucidate the eff ... | 1996 | 28307134 |
| sabal palmetto seed size: causes of variation, choices of predators, and consequences for seedlings. | high variation in seed size, as is common among angiosperms, may be maintained in a plant species when several factors select for seed size. variation may also result from differences among adult plants, such as nutrient and water availability or the amount of photosynthetic tissue. in a study of sabal palmetto seed ecology i found high seed size variation both within- and among-palms, and investigated possible factors maintaining this variation. seed size was positively correlated with the numb ... | 1996 | 28307455 |
| the role of carbohydrate reserves in the growth, resilience, and persistence of cabbage palm seedlings (sabal palmetto). | sabal palmetto (walt.) lodd. ex schultes (cabbage palm) is an arborescent palm common in many plant communities throughout florida, u.s.a., and the caribbean. although its seedlings grow very slowly in forest understories, they survive damage and defoliation well, and the species may increase in dominance following disturbances such as fire, logging, and hurricanes. we investigated the potential importance of total nonstructural carbohydrate (tnc) pools in the ability of cabbage palm seedlings t ... | 1998 | 28307670 |
| quality of rooting environments and patterns of root colonization by arbuscular mycorrhizal fungi in strangler figs in a mexican palmetto woodland. | arbuscular mycorrhizal colonization in strangler figs, spore richness, and abundance of arbuscular mycorrhizal fungi were quantified in epiphytic and ground-rooted trees in a sabal palmetto woodland that had marked heterogeneity in rooting environments for hemiepiphytic plants. an inoculation experiment was performed to assess whether low spore density could limit mycorrhizal colonization. there was no significant difference in mycorrhizal colonization among ficus species, but epiphytic plants i ... | 2007 | 17587066 |
| serenomyces associated with palms in southeastern usa: isolation, culture storage and genetic variation. | serenomyces is a genus belonging to the family phaeochoraceae, which is known to occur only in association with the plant family arecaceae (palms). it is presumed to be one of the causes of a leaf disease referred to as either rachis blight or petiole blight, depending on the palm species affected. the fungus is not readily observed, with few reports in the literature; it cannot be readily isolated from tissue, with only one known instance of it being cultured on artificial media and has no dna ... | 2014 | 24898531 |
| a casualty of climate change? loss of freshwater forest islands on florida's gulf coast. | sea level rise elicits short- and long-term changes in coastal plant communities by altering the physical conditions that affect ecosystem processes and species distributions. while the effects of sea level rise on salt marshes and mangroves are well studied, we focus on its effects on coastal islands of freshwater forest in florida's big bend region, extending a dataset initiated in 1992. in 2014-2015, we evaluated tree survival, regeneration, and understory composition in 13 previously establi ... | 2017 | 28675588 |
