Abstract The Leguminosae, the third–largest angiosperm family, has a global distribution and high ecological economic impor tance. We examine how legume systematic research community might join forces to produce comprehensive phylogenetic estimate for ca. 751 genera 19,500 species of legumes then translate it into phylogeny–based classification. review current state knowledge phylogeny highlight where problems lie, example in taxon sampling resolution. approaches from bioinformatics...

Phylogenetic analysis of the chloroplast-encoded rbcL gene in Leguminosae are consistent with previous hypotheses suggesting that family as a whole is monophyletic, but only two its three subfamilies natural. The earliest dichotomies appear to have involved tribes Cercideae or Cassieae (subtribe Dialiinae), followed by Detarieae/ Macrolobieae, all which members subfamily Caesalpinioideae. remainder divided into clades: (1) Mimosoideae and caesalpinioid Caeasalpinieae (subtribes Ceratoniinae...

Abstract A parsimony analysis was conducted on 319 rbcL sequences, comprising 242 from 194 genera of Leguminosae and 77 other families. Results support earlier conclusions molecular data that a monophyletic is part Fabales includes Polygalaceae, Surianaceae, the anomalous rosid genus Quillaja. Within legumes, results previous analyses were also supported, such as paraphyletic nature Caesalpinioideae monophyly Mimosoideae Papilionoideae.

Abstract While many plant species are considered threatened under anthropogenic pressure, it remains uncertain how rapidly we losing diversity. To fill this gap, propose a Global Legume Diversity Assessment (GLDA) as the first step of global diversity assessment. Here describe concept GLDA and its feasibility by reviewing relevant approaches data availability. We conclude that Fabaceae is good proxy for overall angiosperm in habitats much available. As indicators states, comparison richness...

The Air Telang Protected Forest (ATPF) is one of the most dynamic and essential coastal forest landscapes in South Sumatra, Indonesia, because its location between multiple river outlets, including Musi catchment—Sumatra’s largest dense lowland catchment area. While ATPF areas are covered by mangroves, these have been experiencing severe anthropogenic-driven degradation conversion. This study aims to evaluate land cover changes associated carbon emissions over a 35-year period (1985–2020)...

Abstract Aim Mangroves are intertidal plants with sea‐dispersed propagules, hence their population structure can offer valuable insights into the biogeographical processes driving subdivision in coastal species. In this study, we used molecular markers and ocean circulation simulations to examine effects of currents land masses on genetic major mangrove species Rhizophora mucronata . Location Southeast Asia. Methods We assessed 13 R. populations from continental Asia Sumatra using 10...

The global distribution of mangroves is attributed to interactions between long-distance propagule dispersal and geographical barriers, which are manifest in genetic structuring. Uncovering this structure thus provides a window into the ecological, evolutionary, phylogeographic history mangroves.

Mangrove forests are ecologically important but globally threatened intertidal plant communities. Effective mangrove conservation requires the determination of species identity, management units, and genetic structure.

Biogeographic transition zones are promising areas to study processes of biogeographic evolution and its influence on biological groups. The Mexican zone originated due the overlap Nearctic Neotropical biota, which promoted great diversification. However, since most previous studies in this area were focused revealing phylogeography plants, how historical configuration influenced expansion diversification flora remains almost unknown. Using cycad genus Dioon (Zamiaceae), aimed test whether...

Nucleotide sequences of the chloroplast‐encoded rbcL gene were used to examine phylogenetic relationships genus Salix together with other allied genera family Salicaceae. Phylogenetic analyses strongly suggest monophyly three commonly recognized ( Chosenia, Salix, and Toisusu ). Two monophyletic groups are within larger group. They do not correspond any infrageneric taxa proposed so far. With regard character evolution, it is thought that reduction stamen number from more than two stamens...

Ipomoea pes-caprae (Convolvulaceae), a pantropical plant with sea-drifted seeds, is found globally in the littoral areas of tropical and subtropical regions. Unusual long-distance seed dispersal has been believed to be responsible for its extraordinarily wide distribution; however, actual level inter-population migration never studied. To clarify among populations I. across range, we investigated nucleotide sequence variations by using seven low-copy nuclear markers 272 samples collected...

Niche conservatism is the tendency of lineages to retain same niche as their ancestors. It constrains biological groups and prevents ecological divergence. However, theory predicts that can hinder gene flow, strengthen drift increase local adaptation: does it mean also facilitate speciation? Why this happen?

Species detection using environmental DNA (eDNA) is a biomonitoring tool that can be widely applied to mangrove restoration and management. Compared traditional surveys are taxa-specific time-consuming, eDNA metabarcoding offers rapid, non-invasive cost-efficient method for monitoring biodiversity characterising the spatio-temporal distribution of multiple taxa simultaneously. General guidelines well-established aquatic systems, but habitat-specific still lacking. Mangrove habitats, as...
