Intraspecific plant-soil feedback in four tropical tree species is inconsistent in a field experiment. [PDF]

Am J Bot
Abstract Premise Soil microbes can influence patterns of diversity in plant communities via plant–soil feedbacks. Intraspecific plant–soil feedbacks occur when plant genotype leads to variations in soil microbial composition, resulting in differences in the performance of seedlings growing near their maternal plants versus seedlings growing near ...

The Use of Medicinal Plants in the Riverside Community of the Mazagão River in the Brazilian Amazon, Amapá, Brazil: Ethnobotanical and Ethnopharmacological Studies. [PDF]

Evid Based Complement Alternat Med, 2019
The inhabitants of the floodplain of the Mazagão River in the State of Amapá in the Brazilian Amazon have inherited from indigenous African and Cabocla cultures indications for the use and forms of preparation of medicinal plants to cure diseases of the body and spirit. This study aimed to perform an ethnopharmacological survey of medicinal plants used

Seedling growth declines in warmed tropical forest soils

Biotropica, Volume 55, Issue 5, Page 897-910, September 2023., 2023
The response of tropical forest plants to a warming climate could have a large feedback on further climatic change. To address this, we tested the response of six tree species seedlings to 3 years of in‐situ experimental soil warming. Our study demonstrates that belowground warming causes species‐specific declines in the growth and photosynthesis of ...

Multi‐scale habitat selection of key frugivores predicts large‐seeded tree recruitment in tropical forest restoration

Ecosphere, Volume 12, Issue 12, December 2021., 2021
Abstract Large‐seeded, animal‐dispersed (LSAD) trees include some of the most valuable and threatened species in the tropics, but they are chronically underrepresented in regenerating forests. Toucans disperse many LSAD species, so attracting toucans to regenerating forests should help re‐establish more diverse tree communities.

Biosynthesis of tetrahydrofuran lignans in Virola surinamensis [PDF]

Revista Brasileira de Ciências Farmacêuticas, 2004
The labelled substrates phenylalanine and phenylpropanoid E-isoeugenol were incorporated to 5-methoxy-4-O-methyl-E-isoeugenol (E-isoelemicin) and to the tetrahydrofuran lignan verrucosin in plantlets of Virola surinamensis (Myristicaceae).

Multi‐dimensionality as a path forward in plant‐soil feedback research

Journal of Ecology, Volume 109, Issue 10, Page 3446-3465, October 2021., 2021
In moving the field forward, future plant‐soil feedback research should take a multidimensional approach by explicitly considering cross‐connections between dimensions, including, for example, spatio‐temporal variation in resource availability, and trait–environment relationships across taxonomic and functional groups of plants and soil organisms. This
