TL;DR: In this article, the authors reviewed the literature with regard to the degree of interlinkage between mangroves and adjacent habitats, a research area which has received increasing attention in the last decade.

TL;DR: Knowing on mangrove carbon dynamics has improved considerably in recent years, but there are still significant gaps and shortcomings, and relevant research directions are suggested.

TL;DR: In this article, the authors review the state of knowledge of mangrove vulnerability and responses to predicted climate change and consider adaptation options, based on available evidence, of all the climate change outcomes, relative sea level rise may be the greatest threat to mangroves.

TL;DR: In this article, the authors review 72 published articles to elucidate characteristics of biomass allocation and productivity of mangrove forests and also introduce recent progress on the study of MANGEO to solve the site and species-specific problems.

TL;DR: There is growing research interest in the ethnobiology, socio-economics and management of mangrove forests as discussed by the authors, with harvesting efforts and impacts concentrated in stands that are closer to settlements and easiest to access (by land or by sea).

TL;DR: In this paper, a review of the mangrove literature focusing on eco-physiological and growth constraints to the establishment and early development of seedlings in the intertidal zone is presented.

TL;DR: The Ocypodidae have now been shown to have the same role as Sesarmidae in terms of retention of forest products and organic matter processing in New world mangroves and it seems likely that ants have positive effects on mangrove performance.

TL;DR: While stand structure in mangrove stands is dependent on age, site conditions and silvicultural management, published data indicates that stem densities are higher in restored mangroves than comparable natural stands; the converse is true for basal area.

TL;DR: For S. salsa from the intertidal zone there appears to be selection for slower growth and producing more brown seeds, which may determine the natural distributions of S.alsa populations in different saline environments.

TL;DR: A suite of models have been developed independently by various academic and government institutions worldwide to understand the dynamics of mangrove ecosystems and to provide ecological forecasting capabilities under different management scenarios and natural disturbance regimes as discussed by the authors.

TL;DR: In this article, the authors used Radiocarbon dating of sedimentary sequences to date palaeoecological successions shown by fossil sequences, or long-term sedimentation rates.

TL;DR: The results show that extreme conditions may affect the fitness of eelgrass and, thus, may potentially limit its distribution in coastal and estuarine waters.

TL;DR: The tolerant cultivar could survive submergence apparently because it possessed 1.7-fold more non-structural carbohydrate content before and after submergence compared to the susceptible cultivar and it had a better capability to restore its photosynthetic capacity during post-submergence periods.

TL;DR: Overall, differences among species were likely due to the recalcitrance of decomposing detritus, whilst process rates were controlled by limitation of microbial processes by nutrients and electron acceptor availability.

TL;DR: Recommendations on the molecular markers and on the sampling design of individuals and populations are given within a conceptual context of evolutionary significant units to increase the number of reliable comparisons of genetic variables across species or regions.

TL;DR: Evidence is added to evidence that rafting of seeds on floating reproductive shoots is an important dispersal strategy for eelgrass, allowing for colonisation of new areas and for recolonisation after die-back events.

TL;DR: Genetic diversity, population structure and interrelationships were investigated in eight populations of the common reed in the Po Plain, Italy, by means of amplified fragments length polymorphisms (AFLPs) and random amplified polymorphic DNAs (RAPDs).

TL;DR: The genetic uniformity of invasive A. donax suggests that classical biological control of the species could be successful and a lack of genetic diversity in the invaded range simplifies identification of native source populations to search for natural enemies that could be used as biocontrol agents.

TL;DR: It is suggested that the salt-induced Pn reduction in the two mangrove species is correlated with the ability to exclude Na+ and Cl− from the chloroplast, rather than with the bulk leaf salt concentration.

TL;DR: This paper reviews the available retrospective methods, and highlights the transdisciplinary way in which retrospective research on a scale between months and centuries can be carried out, but it also includes methods on larger scales that may be marginally relevant.

TL;DR: This study showed that L. peploides and L. grandiflora possess an allelopathic activity that influences the water quality throughout the year and may contribute to the great success of these two invasive Ludwigia in Europe.

TL;DR: The response of RLCs to changes in ambient irradiance varied with the long-term photoacclimation status of the samples, and an inverse relationship was consistently found between αRLC and NPQ, both on LL and HL cultures, causing strong correlations.

TL;DR: In this article, the authors examined the ability of lake and landscape features to predict a variety of macrophyte cover metrics using 54 north temperate lakes using univariate regression analyses.

TL;DR: The [Cd 2+ ] values inhibiting the photosynthetic parameters were greater than those reported for several other species, which suggests that J. rapens may have some degree of tolerance to this toxic metal.

TL;DR: In this article, the authors used echo sounding data to assess the distribution and colonization depth of submerged macrophytes in Lake Balaton and found that the influence of light and exposure on plants could be distinguished by considering the complex interplay of site-specific morphometry and the stochastic wind field in a highly simplified manner.

TL;DR: Germination of V. americana seeds was enhanced and ungerminated seeds were found to maintain high viability, especially at salinities of 10 psu that can have significant negative effects of shoot growth survival, suggesting that seeds may serve as a source of reproductive material for bed recovery after periods of drought or other stressful conditions in estuarine systems.

TL;DR: It is shown that U. lactuca exhibits negative allelopathic effects on harmful bloom-forming microalgae, and a long-term inhibition might need the continuous addition of compounds originated from macroalgae.

TL;DR: Genetic similarity was highest within each of the sites, indicating a low degree of gene flow between populations, and it is recommended that any future restoration and conservation projects use only locally eco-sourced materials for population augmentations.

TL;DR: Patch survival increased with patch size and no direct removal was observed among patches of 5 shoots or more, and most patches grew along the study, shifting patch distribution towards larger sizes.

TL;DR: The results suggest that fungal N demands can be fulfilled at relatively low levels of dissolved nitrate and further increases in the nutrients availability may not result in enhanced fungal activity.
