Bruguiera hainesii (Rhizophoraceae) is one of the two Critically Endangered mangrove species listed in the IUCN Red List of Threatened Species. Although the species is vulnerable to extinction, its genetic diversity and the evolutionary relationships with other Bruguiera species are not well understood. Also, intermediate morphological characters imply that the species might be of hybrid origin. To clarify the genetic relationship between B. hainesii and other Bruguiera species, we conducted… Expand

Bruguiera hainesii C.G.Rogers (Rhizophoraceae), an endangered species recently discovered in Australia
TLDR
The critically endangered Bruguiera hainesii C.G.Rogers (Rhizophoraceae) is newly recorded as occurring on the Australian mainland in north Queensland within the city limits of Cairns. Expand
Observations on Flowers of the Genus Bruguiera from Setiu Mangrove Areas, Terengganu
TLDR
The results showed that B. rhynchopetala were the largest flowers as compared to B. gymnorhiza and B. sexangula, and suggested the same pollination strategy as B. cylindrica, while the large herkogamy in the other four species might indicates cross-pollination by pollinating agents, possibly birds.

TLDR
This comprehensive plant checklist will be a primary reference for the management of the newly gazetted Setiu Wetlands State Park covering more than 400 hectares of lands and water bodies and investigated the most important plants used by the local communities. Expand

Bruguiera (Rhizophoraceae) in the Indo West Pacific: A morphometric assessment of hybridization within single-flowered taxa
TLDR
The first putative hybrid tree species of the genus Bruguiera (Rhizophoraceae), B. × rhynchopetala, is reported from mangrove forests of China and Australia, and is acknowledged as B. sexangula with parent species restricted to different parts of the Indo-West Pacific. Expand
Systematic affinities of Rhizophoraceae and Anisophylleaceae, and intergeneric relationships within Rhizophoraceae, based on chloroplast DNA, nuclear ribosomal DNA, and morphology.
TLDR
A cladistic analysis of sequences from the chloroplast gene rbcL was used to determine the systematic affinities of Rhizophoraceae and Anisophylleaceae and identifies Erythroxylaceae as sister group within the Malpighiales, supported by several morphological and anatomical characters. Expand
The Bruguiera (Rhizophoraceae) Species in the Mangroves of Singapore, Especially on the New Record and the Rediscovery
TLDR
It is suggested that the series or numbers of colleters (finger-like glandular structures inside the base of stipules) could be an aid for identifying members of Rhizophoraceae especially in the absence of reproductive structures. Expand
Inferences of evolutionary history of a widely distributed mangrove species, Bruguiera gymnorrhiza, in the Indo-West Pacific region
TLDR
The results indicated that these two genetic clusters derived from their ancestral population whose effective size was much larger compared to the two extant clusters and function as a geographical or land barrier to prevent gene flow between the West and East clusters. Expand
Pollination in Bruguiera gymnorrhiza and Rhizophora mucronata (Rhizophoraceae) in Ishigaki Island, the Ryukyu Islands, Japan
TLDR
In this locality these three taxa are at their northernmost geographic limit, but plants show no features of reproduction abnormal for the species, even though they are likely to be ecologically limited. Expand
Genomic Markers Reveal Introgressive Hybridization in the Indo-West Pacific Mangroves: A Case Study
TLDR
Genomic data provide insights into the hybridization dynamics of mangrove plants by helping detect novel taxa and/or define species boundaries and concludes that B. × rhynchopetala has not evolved into an incipient hybrid species, and its persistence can be explained by recurrent hybridization and introgression. Expand
Genetic differentiation and phylogeography of partially sympatric species complex Rhizophora mucronata Lam. and R. stylosa Griff. using SSR markers
TLDR
The results serve as the foundation for the conservation genetics of R. mucronata and R. stylosa and highlighted the need to recognize the genetic distinctiveness of closely-related species, determine their respective genetic structure, and avoid artificially promoting hybridization in mangrove restoration programmes.

The bird species Hypsipetes amaurotis and Zosterops palpebrosa var. yonakuni, but no insects, were recorded regularly feeding on flower-nectar of Bruguiera gymnorrhiza in the Miyara River BiologicalExpand
Reconstructing Hybrid Speciation Events in the Pteris cretica Group (Pteridaceae) in Japan and Adjacent Regions
TLDR
The combined results of cytology and the phylogenetic trees suggested that the sexual diploid P. kidoi had played a central role in the diversification of polyploid species in the P. cretica group. Expand
Mangroves as Nurseries: Shrimp Populations in Mangrove and Non-mangrove Habitats
TLDR
Abundance and size composition of the major species suggest a strong nursery role for the riverine mangrove, limited nursery use of the islandMangrove and a non-nursery use in the tidal flat. Expand
