“…Such ontogenetic niche shifts have been documented in other taxa (e.g., Dalling et al 2001, Miriti 2006, Molofsky & Augspurger 1992, Parrish & Bazzaz 1985, Redondo-Gomez et al 2008, Song et al 2008, Thomson et al 1996. Such niche shifts can potentially restrict the conditions under which a taxon can persist; conditions that permit survival of both stages must be present within a given location, and this is a situation that is likely to be less common than the occurrence of conditions that permit the survival of only one stage.…”

“…Seasonal or successional changes in vegetation cover, competitive environment, or abiotic factors such as water or nutrient availability often change over the course of the life span of individuals, as does the organisms' exposure to particular environmental factors over the course of development (Bazzaz 1991). When the environment itself changes during ontogeny in a manner that matches the niche, ontogenetic niche shifts could actually be advantageous (Anderson et al 2009, Redondo-Gomez et al 2008.…”

Germination behavior is one of the earliest phenotypes expressed by plants. This fact has several consequences for the evolution of postgermination traits, ecological niches, and geographic ranges. By determining the conditions that plants experience after they germinate, germination influences phenotypic expression of postgermination traits, natural selection on them, and their genetic basis. The breadth of germination niches may influence the ecological breadth and geographic ranges of species. Because germination is expressed early, it is frequently subjected to natural selection before other traits are expressed. We review evidence for natural selection on and adaptation of germination and discuss how the breadth of the germination niche is associated with the ecological niche and range of plant species. We review evidence for the coevolution of germination and postgermination traits and compare germination to postgermination niches. Finally, we discuss how germination responses to altered environments can influence species distribution and the evolution of postgermination traits after environmental change.

“…It is 25.5 ± 0. 86 16,265 in S. monoica and 10,175 in S. nudiflora. The pollen-ovule ratio is equal to the pollen out per anther due to oneovuled flowers in all the three species.…”

“…Chapman (1947) also reported three principal varieties, vulgaris, macrocarpa and flexilis, based on growth habit and seed size. Redondo- Gomez et al (2008) reported that several Suaeda species exhibit seed dimorphism and produce both brown and black seeds simultaneously and these varying colorations reflect two different dormancy and germination strategies for survival in saline habitats. Ponnamperuma (1984) explained that occurrence of different growth forms reflect different soil conditions present in high and low salt marshes due to difference in aeration levels.…”

Floral biology, sexual system, breeding system, pollinators, fruiting and seed dispersal aspects of five mangrove associate species, namely, Clerodendrum inerme, Derris trifoliata, Suaeda maritima, S. monoica, and S. nudiflora were studied. All these species are hermaphroditic, self-compatible, and exhibit mixed breeding systems adapted for pollination by external agents. C. inerme and D. trifoliata are principally entomophilous, while Suaeda species are ambophilous. The study suggests that these plant species are important constituents of mangrove forests. C. inerme and D. trifoliata are useful in stabilizing the banks of back water creeks, while Suaeda species are useful to carpet the saline areas and desalinate the soils which are subsequently useful for agricultural activities. Articolul prezintă studiul asupra biologiei florale, sistemului sexual, sistemului de creștere, polenizatorilor, rodirii și răspândirii semințelor la cinci specii de mangrove asociate, Clerodendrum inerme, Derris trifoliata, Suaeda maritima, S. monoica și S. nudiflora. Toate aceste specii sunt hermafrodite, auto compatibile și prezintă sisteme de creștere mixte adaptate pentru polenizare de către agenții externi. C. inerme și D. trifoliata sunt în principal entomofile în timp ce speciile Suaeda sunt ambophilous. Studiul sugerează că aceste specii de plante sunt constituenți importanți ai pădurilor de mangrove. C. inerme și D. trifoliata sunt utile în stabilizarea malurilor cursurilor de apă, în timp ce speciile Suaeda sunt utile pentru covorul zonelor saline și desalinizarea solurilor care sunt ulterior utile pentru activități agricole. ZUSAMMENFASSUNG: J. S. R. Aluri et al. -Reproductive biology of mangrove plants (31 ~ 68) 32 INTRODUCTIONMangrove conservation has received an increased importance in the recent past as research has increased the understanding of the values, functions, and attributes of mangrove ecosystems and the role they play in providing important ecological services and livelihoods for the mangrove associated communities. Mangrove forests are among one of the world's most productive tropical ecosystems. They are now one of the most threatened ecosystems in the world due to natural and demographic pressures (Roy and Krishnan, 2005). The mangrove vegetation is comprised of unique plant communities consisting of evergreen trees and shrubs belonging to several unrelated families growing in tropical and subtropical intertidal regions where there is constant intertidal exchange of sea water and freshwater (Spalding et al., 1997).The focus of research on the reproductive biology of mangrove plants has almost exclusively been on the fruit and seed or seedling dispersal stage. Surprisingly, less is known about floral biology, pollination, and breeding systems, although knowledge of the effectiveness of floral mechanics and genetic isolating mechanisms is an important prerequisite to the study of successful dispersal and establishment (Primack et al., 1981;Tomlinson, 1986;Juncosa and Tomlinson, 1987;Clarke and Meye...

“…It is possible that a stable quencher was formed in presence of NaCl and that it did not decay during the dark adaptation period before measurement. Alternatively, it could be concluded as well that under low NaCl conditions plants are more prone to photoinhibition, through damage to PSII reaction centres (Redondo-Gómez et al 2010). Redondo-Gómez et al (2007 and found that absence of salt represented an environmental stress factor for Atriplex portulacoides and Suaeda splendens, respectively, since there was a marked midday reduction in F v /F m at 0 mM NaCl.…”
