However, the lower initial clonal densities and colonization by other plant species resulted in reduced overall dominance by S. alterniflora in the two more-interior locations. Patterns of FHT were not explained by distance We surveyed 6 forests in Charlotte Harbor (2002, 2003, and 2005) and 16 in, Tampa Bay, Florida (2001, 2002, 2003, and 2005) for total numbers of reproducing trees and trees heterozygotic for albinism, that produce both normal and albino propagules. The greatest selfing (32%) occurred in young (2-yr-old) patches with low diversity. Reexamination of pore water sulfide concentrations and redox, Impact and Response of Southwest Florida Mangroves to the, succession in restored and natural mangrove forests in south-, red mangroves as a bioassay of contamination history in Tampa, 2002.

Our goal was to determine diversity and to ascertain potential population bottlenecks two decades after the event. These results suggest a possible fitness trade-off between clonal growth and the opportunity for outcrossing. Ph.D. Dissertation, Louisiana. In addition to precocious reproduction, propagule size of R. mangle … ... • Respuestas de los manglares a la variabilidad climática: (Bacon, 1994;Dugan, 1994;Ellison, 1994;Field, 1995;Jiménez, 1999;McKee, 2004;Milbrandt et al., 2006; ... Incluso durante los últimos 56 años, los manglares de Key West Florida se han expandido hacia el mar y hacia el continente, a pesar de los huracanes y aún con un incremento del nivel del mar equivalente a 23 cm por cada 100 años. Effects of light and intertidal position on, in a Caribbean mangrove forest: Interact-, Proceedings of the International Symposium. Rhizophora mangle is a small aquatic tree or shrub, that can reach heights between 5-20m and a trunk diameter between 20-50cm. Interested in research on Rhizophoraceae?

Selfing, a tree that has colonized a remote site to, in the absence of other trees and will increase, degree of carry-over of maternal genes to the next, generation. KeywordsRed mangroves-Tampa bay-Maternal genotype-Ecological genetics-Genotype × environment. Since the last major freeze event in 1989, the limits of Rhizophora mangle L. have rapidly extended poleward on the US Atlantic coast (Cavanaugh et al., 2014) and the species is reaching sexual maturity early there (“precocious” reproduction) (Dangremond and Feller, 2016). Effects on genetic diversity only were studied in a second set of sites in southeastern Louisiana (near Bay Junop), where the dieback was more widespread. Enter your International Society for Horticultural Science e-mail or user number. Surface elevation change in mangroves reflects the balance between surface sedimentation processes and sub-surface processes and, exceptionally, responses to hurricane and tsunami impacts. Nowadays Rhizophora mangle grows between latitude 25 north and 35 south from the … Frente al desafío que enfrentan los sistemas económicos, sociales y ecológicos de la zona costera, se presentan evidencias de estructura funcional del sistema ecológico de manglar, revisitando la hipótesis planteada por Yáñez-Arancibia et al. 4 S. alterniflora clonal genotype influenced the degree of suppression of the previously dominant Salicornia bigelovii as well as facilitation of recruitment and growth by other plant species. total soil nitrogen, and total soil carbon were not significantly affected by maternal so regression statistics are not reported. A field experiment revealed that S. alterniflora height and total stem length varied with genotype, while stem density and flowering stem density did not. The bark is gray to brown, thin when a sapling, becoming thick and furrowed with maturity (Duke, 1983). There was no signi, December 2005 data) was minimal, likely in part as, cruitment declined with increasing canopy, but was greater in plots that had large num, reproduction is emphasized by co-occurrence of, and dispersal of propagules, although maj, canes may strand many propagules at elevations, higher than they can survive. Differences between edge and center are interpreted as differences in clone morphology. Genetic diversity was relatively unaffected by the dieback at either the Sabine or Bay Junop sites. Es una especie adaptada a ambientes salinos y tolera mayor salinidad que los otros mangles. Mangroves, hurricanes, and lightening strikes: Assessment of, Hurricane Andrew suggests an interaction across two differing. ... And in Hawaii, Rhizophora mangle from Florida were introduced by the American Sugar Company in 1902 in an effort to maintain erroiding coastlines, and later Bruguiera gymnorrhiza and Conocarpus erectus were also introduced. The black mangrove’s propagule must drift for at least 14 days. High incidence of selfing also greatly, reduces genetic diversity and can increase the, deleterious effects of inbreeding depressi, to mid intertidal habitat, the reduced genetic, diversity caused by selfing may affect its ability to, adapt to future changes (e.g., conditions in, seedlings able to survive following colonization o, disturbed areas. forest: A test of the dominance-predation model in northern, in neotropical forests: Biotic and abiotic factors affec, seedling survival and growth. es Rhizophora mangle es la especie más común dentro de su distribución y de importancia para el funcionamiento del ecosistema. In the case of Rhizophora, which has little capacity for vegetative propagation, the presence of a high density of surviving seedlings becomes critical; where there are few remaining seedlings, forest replacement by Avicennia and Laguncularia, which can coppice, is likely (Tomlinson, 1986; Mangroves migrate northward in Florida and colonize marshes historically dominated by salt marsh species. 8 need Most mangroves live on muddy soils, but they also can grow on sand, peat, and coral rock. located in areas of management concern (i.e., restricted connection) had significantly lower stem diameter at breast height Our SEM results indicate that outcrossing increases in this predominately selfing species under conditions of cold and anthropogenic stress, and that this increases reproductive output in the population. were found among species in the size of severely impacted trees. - REARING METHODS AND EFFECTIVENESS OF POLLINATORS IN CROP GERMPLASM REGENERATION, 437_26 FOOD SOURCES IN THE MANAGEMENT OF BUMBLEBEE POPULATIONS AROUND CRANBERRY MARSHES, 437_27 THE NEED FOR “EXTENDED CARE” IN CONSERVATION: EXAMPLES FROM STUDIES OF RARE PLANTS IN THE WESTERN UNITED STATES, 437_28 DIVERSITY AND OVERLAP IN POLLEN SOURCES OF THREE SPECIES OF STINGLESS BEES (APIDAE, MELIPONINAE) IN COSTA RICA, 437_29 POLLINATION ECOLOGY OF PLATONIA INSIGNIS MART. colonize most study plots, possibly because water, access to the site was restricted to a single flushing, channel and to periods of very high tides that, the percent canopy loss at four locations on Sanibel and Captiva, Islands in Charlotte Harbor, Florida and in December 2005, relative to the number of seedlings in April 2005 (hurricane, were calculated via regression analysis. DNA extracted from leaf samples in the Sabine and Bay Junop sites was used to construct genotype profiles using AFLPs and analyzed using the complement of Simpson’s Index (1-D), the richness measure G/N, average heterozygosity , and the estimated proportion of polymorphic genes We hypothesized that stem density, live aboveground biomass, and genetic diversity would be significantly reduced compared to predieback conditions and to nearby unaffected marshes. Further, we wished to determine if mutation rate varied with the stressors and if that affected stand reproduction. The germinated seed can root if it lands on sediment. Rhizophora mangle: Red Mangrove 2 Description Height: 20 to 75 feet Spread: 20 to 30 feet Plant habit: round Plant density: dense Growth rate: moderate Texture: medium Foliage Leaf arrangement: opposite/subopposite Leaf type: simple Leaf margin: entire Leaf shape: elliptic (oval) Leaf venation: none, or difficult to see Leaf type and persistence: evergreen Leaf blade length: 1½ to 6 inches The landfall of Hurricane Charley, a category 4 storm, left pronounced disturbances to Still, the genetic diversity ofS. The number of genotypes in the experimental pool was based on the number of trees at the collection sites that were mast producing that year (i.e., had sufficient numbers of propagules for suitable replication in the experiment). Reproduction: Rhizophora mangle flowers are thought to be self pollinated or wind pollinated. Biparental inbreeding was minimal in all populations, never exceeding 1%. Rhizophora mangle is self‐compatible and usually wind‐pollinated. a dominant salt marsh plant (Travis et al. State University, Baton Rouge, Louisiana. The two fringing mangrove populations (Hurricane Hole and New Found Bay) evinced low observed heterozygosity and high inbreeding coefficients, while the fully forested sites showed higher heterozygosity and lower inbreeding frequencies. alterniflora-dominated marshes may be promoted by occasional disturbance events, which produce open areas in which seedling recruitment can occur. The, authors also wish to thank J. N. ‘‘Ding’’ Darling National Wildlife, Refuge for permission to establish and monitor forested study, plots. However, despite its importance, the underlying drivers of mangrove dispersal have typically been studied in isolation, and a conceptual synthesis of mangrove oceanic dispersal across spatial scales is lacking. mangrove forests on southwest Florida barrier islands. 7 We hypothesize that as genotypic diversity increases in populations of a dominant plant species like S. alterniflora, the number and diversity of interactions with other species will increase as well. Stem densities and biomass levels approached predieback conditions 14 months after first observance of the dieback in the Sabine marsh and were similar to or exceeded the same measures for a nearby unaffected marsh. the resiliency of estuarine habitats is unknown.

Different areas of these mangrove forest, and compare with data from Tampa Bay, Flo, Because propagule dispersal is pre-domina, colonization rates can be strongly affected by, We also provide ancillary information on the, outcrossing rate in each stand. , K. A. Rhizophora mangle ne possède pas de glandes à sel, on pense que c'est principalement au niveau des racines que se fait l'absorption différentielle de l'eau et du sel. Hurricane Charley devastated large areas of mangroves in Charlotte Harbor, Florida, and Sonneratia alba Griff. on heterozygotic trees expected with 100% selfing was used to estimate outcrossing. Reproductive aspects of life history are known to be important in recovery following disturbance in many plant species although However, either adaptation or plasticity provides a basis for maintenance of Rhizophora dominance over a wider range of environmental conditions and may be important for adaptation to conditions that will vary The white mangrove’s dispersal period is the shortest at 5 days, which also includes germination. Under optimal conditions, this mangrove tree can grow to heights of over 80 feet (25 m), however, in Florida, red mangroves typically average 20 feet (6 m) in height. Outcrossing of sentinel trees was 2.5 times greater, in Charlotte Harbor (mean site−1=33.6±6.7%; with 17% of forest sites completely selfing) than in Tampa Bay (mean site−1=13.4±4.7%; with 40% of sites completely selfing), although the implications for seedling recruitment of this difference are Recovery following disturbance is influen, al, soil edaphic factors, and the suite of seedling, predators in the area. More new recruits occurred in sites that had higher densities of pre-stormRhizophora seedlings and greater relative dominance byRhizophora. We used significant, 3:1 ratio of green:albino propagules in sent, found at sites surveyed to estimate the outcross, rate (100% selfing produces propagules in a 3:1, ratio, see Lowenfeld and Klekowski [1992] and, Proffitt and Travis [2005] for details). benthos at McMurdo Sound, Antarctica, p. 81–96. While no data are available regarding the number of genotypes that may naturally be found at the spatial scale used in this experiment, both reproduction and recruitment of R. mangle is generally low in the years following hurricanes, ... Propagules remained on adult mangrove trees after Hurricane Matthew, and propagule abundances were similar in vegetated microhabitats for the 3 observed propagule seasons (Fig. for assistance with 2003 surveys in Charlotte Harbor. -Authors. impacts on mangrove forest structure and an evaluation of. The authors acknowledge funding from the U.S. Geological, Survey Tampa Bay Project (C. E. Proffitt and S. E. Travis) and the, Sanibel-Captiva Conservation Foundation’s Core Research Pro-.

SYSTAT for Windows, version 10.2. However, recovery will ultimately be contingent upon hydrological connectivity and environmental improvements. Flowering of R. mangle is induced by increasing temperatures and the onset of rains. 2005). not known. density in regions closer to the eyewall where there were complete losses of crown structures. In theory, this migration should be facilitated by greater numbers of propagules stemming from increased reproductive activity and greater genetic variability caused by outcrossing. Seedlings were spatially very patchy and tended to occur near clones that probably produced them. In northeast Florida, the black mangrove Avicennia germinans is expanding into salt marshes, where it interacts with the dead litter (wrack) of the native marsh cordgrass Spartina alterniflora . Nitrogen limitation of growth and nutrient dynamics in. C. E. Proffitt and S. E. Travis thank Carole McIvor, various staff of, the U.S. Geological Survey for assistance with logistics and field, work in Tampa Bay, and Ernie Estevez of Mote Marine Laboratory. Although rainfall is predicted to increase by about 25% globally by 2050 in response to climate change (Houghton et al., 2001), rainfall is predicted to decrease in most subtropical regions, especially among the poleward margins of the subtropics (Solomon et al., 2007). In the region farthest from the eyewall, increases in canopy Leaf and stipule production showed a seasonal trend, decreasing during the cool and dry winter months. from the bay mouth or the degree of urbanization. These ecosystems provide a suite of services including carbon storage, pollution and nutrient abatement, soil formation, fisheries support, and flood and storm protection. Evidence from field observations and the results of the genetic analyses suggest that seedling recruitment is an important factor in the recovery of both the Bay Junop and C83 sites, although re-growth from surviving below-ground rhizomes appeared to dominate recovery at the latter site. Further, we find that increased mutation rates suppress stand reproductive output but there is no significant relationship between outcrossing and mutation rate. Still, the genetic diversity ofS. cohorts of seedlings from different maternal trees, out as a covariate (Devlin 2004; Proffitt and Trav, unpublished data). For this purpose, we sampled maternal tissue and seeds from discrete patches in the field and then genotyped both maternal and seedling tissue (germinated in a growth chamber) using standard molecular protocols. Rhizophora mucronata is very important locally as a source of wood and non-wood products to the local community (Dahdouh-Guebas et al., 2000; Kairo et al., 2009). 1994) in … The study of the water relations and anatomy during vivipary of this species is crucial, because it could be a plant model to understand productivity and seedling establishment for mangrove conservation programs. N numbers are shown in association with the bars. 2002.

Such distribution is possible because it has various physiological and anatomical adaptations, among which viviparity stands out, where the parent plant has a close relationship with the growing propagules to provide nutrients, water and carbohydrates required. The trend lines were calculated via regression analysis. We investigated five populations of red mangrove (Rhizophora mangle) from St. John, USVI, an UNESCO Biosphere Reserve, which were impacted by Hurricane Hugo in 1989. A trend, seen of more new recruits to sites that had more, suggest that most of the new recruitment was from, local trees within or near the plots and is consistent, Sengupta et al. Reduced reproduction in Charlotte Harbor was accompanied by fewer Determinants of mangrove species distribution, , K. L. 1995. The seafaring propagules (fruits and seeds) of mangroves represent an excellent example of such passive dispersal. Here, we review current knowledge on mangrove propagule dispersal across the various stages of the dispersal process. . The mangrove´s incredible method of reproduction - Duration: 2:03. Seedlings in canopy removal areas had higher survivorship, grew twice as fast, produced more leaves, and had less than half the herbivory of seedlings growing beneath an intact canopy. field experiment to assess differences in responses among 86 half-sibling (same maternal tree) seedling families of the red This effect was independent However, there was a significant positive relationship between tree size Elevation differences over distances of a few meters influenced total stem length and flowering stem density but not other response variables. from Donna Devlin, David Crewz, and two unidentified reviewers.
