The Key Role of Vicariance for Soil Animal Biogeography in a Biodiversity Hotspot Region

Global Ecology and Biogeography, Journal Year: 2025, Volume and Issue: 34(5)

Published: April 27, 2025

ABSTRACT Aim The Indo‐Australian Archipelago is known as a biodiversity hotspot with high levels of endemism typically ascribed to vicariance reflected by the ‘Wallace's line’. However, it unknown how has affected belowground biodiversity, especially process‐based beta diversity. Here, we relate diversity soil oribatid mite (Oribatida, Acari) assemblages geographic distance well climatic and factors explore shaping mites across 11 regions Archipelago. Location Time Period Present. Major Taxa Studied Oribatida, Acari. Methods We compiled list 2549 species in investigated level at species, genus family level. then summarised biogeographical dissimilarity patterns using ordination clustering methods compared zoological boundaries based on aboveground taxa such Wallace's, Lydekker's, Weber's Holt's lines. integrated data geography, climate reveal key drivers compositional among Mantel tests. Results Generally, was high; they formed three groups (west New Guinea, Guinea south Guinea) changing from northwest southeast. reflect integrate lines Weber, Lydekker Holt. Species turnover generally correlated distance, reflecting critical role dispersal‐limited mites. Main Conclusions Our results, for first time, demonstrate contrasting below‐ organisms Archipelago, elucidate distance‐based structured animal this region.

Phylogenetic position, supplementary description and phytochemical analysis of Camellia hekouensis (Theaceae), a critically endangered tree native to Hekou, Yunnan, China

PhytoKeys, Journal Year: 2025, Volume and Issue: 256, P. 185 - 195

Published: May 29, 2025

Camellia harbors unique diversity along Sino-Vietnamese border. Some species of them are under threat due to human activity. Camelliahekouensis, a native Hekou, Yunnan, China, was once considered extinct as the previously known "last living tree" died in 2024. Fortunately, 11 in-situ and 32 ex-situ trees have been protected propagated by staff Hekou Administration Branch Dawei Mountain National Nature Reserve Yunnan with their great unpublicized efforts. Molecular phylogenetic analysis suggests that C.hekouensis is nested main clade CI forms C.corallina, C.gracilipes C.pubicosta, which generally distributed Vietnam. Morphological characters capsule seed supplementally described. The leaves contain 1.18 mg/g theobromine, disagrees previous chemotaxonomic claim. Though economic ecological values little for C.hekouensis, should be conserved effectively promptly prevent extinction.

Southeast Asia is a biodiversity hotspot characterized by complex paleogeography, and its Polypodiopsida flora particularly diverse. While hybridization recognized as common in ferns, investigations into the relationship between events fern diversity are notably lacking. Lecanopteris s.s., an ant-associated fern, has been subject to debate regarding species delimitations primarily due limited DNA markers sampling. Our study integrates 22 newly generated plastomes, transcriptomes, flow cytometry of all native along with two cultivated hybrids. objective elucidate reticulate evolutionary history within through integration phylo-biogeography reconstruction, gene inference, genome size estimation. Key findings our include: (1) An enlarged plastome Lecanopteris, attributed extreme expansion Inverted Repeat (IR) regions; (2) The traditional ‘pumila’ ‘crustacea’ groups paraphyletic; (3) Significant cytonuclear discordance flow; (4) Natural introgression ‘darnaedii’ groups; (5) L. luzonensis maternal parent ‘Yellow Tip’, pumila suggested possible paternal parent; (6) ‘Tatsuta’ hybrid crustacea; (7) first diverged during Neogene then middle Miocene climatic optimum Indochina Sundaic regions. In conclusion, biogeographic speciation have profoundly shaped past climate changes geodynamics Asia. Dispersals, act pivotal factors trajectory Lecanopteris.
