An infrageneric classification of the genus Lejeunea (Marchantiophyta: Lejeuneaceae) using molecular phylogeny and morphology
Background and aims – The genus Lejeunea, with about 375 accepted species, is one of the most species-rich and intricate genera of liverworts. Here, we present the first integrative, worldwide infrageneric classification of Lejeunea based on morphology and molecular-phylogenetic analyses. Material…

Extending the fossil record of Miocene neotropical epiphyte communities
Dominican amber (15–20 Ma) and Mexican amber (15–23 Ma) are valuable sources of fossil epiphytic bryophytes, ferns, and lichens. Both ambers derive from resins of Hymenaea, a genus in the Fabaceae family still occurring in Mexico, Central America, and the Caribbean today. The amber inclusions…

Volatile Organic Compounds of Bryophytes from Peninsular Malaysia and Their Roles in Bryophytes
Volatile emissions from 22 bryophyte species from Peninsular Malaysia were collected using a dynamic headspace technique and analyzed by gas chromatography–mass spectrometry (GC-MS). Thirty organic compounds (VOCs) from eight different groups were detected in bryophytes from the montane forest in…

Can Joint Carbon and Biodiversity Management in Tropical Agroforestry Landscapes Be Optimized?
Managing ecosystems for carbon storage may also benefit biodiversity conservation, but such a potential ‘win-win’ scenario has not yet been assessed for tropical agroforestry landscapes. We measured above- and below-ground carbon stocks as well as the species richness of four groups of plants and…
