BIODIVERSITY INDICATOR GROUPS OF TROPICAL LAND‐USE SYSTEMS: COMPARING PLANTS, BIRDS, AND INSECTS
TLDR
Although biodiversity of land-use systems showed taxonomic group- and guild-specific differences, most groups were affected in a similar way by habitat modifi- cation, and land- use systems such as secondary forests and agroforestry systems supported relatively high numbers of species and might play a significant role for biodiversity conservation in tropical landscapes.

Tradeoffs between income, biodiversity, and ecosystem functioning during tropical rainforest conversion and agroforestry intensification
TLDR
It is concluded that low-shade agroforestry provides the best available compromise between economic forces and ecological needs, and Certification schemes for shade-grown crops may provide a market-based mechanism to slow down current intensification trends.

Tree diversity in primary forest and different land use systems in Central Sulawesi, Indonesia
We studied the tree communities in primary forest and three different land use systems (forest gardens, ca. 5-year-old secondary forests, cacao plantations) at 900–1200 m elevation in the environs of…

World checklist of hornworts and liverworts
TLDR
The first-ever worldwide checklist for liverworts and hornworts is presented that includes 7486 species in 398 genera representing 92 families from the two phyla, providing a valuable tool for taxonomists and systematists, analyzing phytogeographic and diversity patterns, aiding in the assessment of floristic and taxonomic knowledge, and identifying geographical gaps.

Methane emissions from tank bromeliads in neotropical forests
Methane concentrations above tropical forests in the neotropics are high, according to space-borne observations. Flux measurements in the field suggest that tank bromeliads, herbaceous plants common…

Vertical stratification of vascular epiphytes in submontane and montane forest of the Bolivian Andes: the importance of the understory
TLDR
Canopy epiphytes (occurring  > 90% in tree zones Z3–5) were mainly represented by orchids and ferns, many with special adaptations to drought stress such as pseudobulbs, succulence, and poikilohydry.

Towards a natural classification of liverworts (Marchantiophyta) based on the chloroplast gene rbcL
TLDR
The results indicate a subdivision of Marchantiophyta into three well sup- ported classes assigned as Haplomitriopsida, Marchantiopsida and Jungermanniopsida which may represent the oldest extant lineage of land plants.
