Inferring species interactions in tropical forests [PDF]

Proceedings of the National Academy of Sciences, 2009
We present 2 distinct and independent approaches to deduce the effective interaction strengths between species and apply it to the 20 most abundant species in the long-term 50-ha plot on Barro Colorado Island, Panama. The first approach employs the principle of maximum entropy, and the second uses a stochastic birth–death model.

Evaluation of lodgepole pine (Pinus contorta Dougl. ex Loudon) on a provenance plot situated in a formerly air-polluted area of the Krušné hory Mts. at the age of 34 years

Journal of Forest Science, 2018
The article evaluates 27 provenances of three subspecies of lodgepole pine on the Kovářská research plot (Krušné hory Mts.). The plot is part of a series of three established plots in various stand conditions.

Third-generation sequencing and metabolome analysis reveal candidate genes and metabolites with altered levels in albino jackfruit seedlings

BMC Genomics, 2021
Background Most plants rely on photosynthesis; therefore, albinism in plants with leaves that are white instead of green causes slow growth, dwarfing, and even death.

Factors influencing successful establishment of exotic Pinus radiata seedlings with co-introduced Lactarius deliciosus or local ectomycorrhizal fungal communities

Frontiers in Microbiology, 2022
An introduction of exotic or non-native trees may fail due to a lack of suitable fungal partners. We planted exotic Pinus radiata in Xifeng, Guizhou Southwest China. Strategies to introduce P.

Comparison of growth development of micropropagated and generatively reproduced wild cherry (Prunus avium (L.) L.) on the Polná demonstration plot (Czech Republic) up to the age of 15 years

Journal of Forest Science, 2016
Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristics of cherry trees were determined each year during the

Spatiotemporal distribution patterns of soil nematodes along an altitudinal gradient in the cold temperate zone of China

Global Ecology and Conservation, 2023
As important components of the cosmopolitan soil biota, soil nematodes are found at multiple trophic levels of the belowground food web and play an important role in soil function.

Markedly Divergent Tree Assemblage Responses to Tropical Forest Loss and Fragmentation across a Strong Seasonality Gradient [PDF]

, 2015
We examine the effects of forest fragmentation on the structure and composition of tree assemblages within three seasonal and aseasonal forest types of southern Brazil, including evergreen, Araucaria, and deciduous forests.

Third-generation sequencing found LncRNA associated with heat shock protein response to heat stress in Populus qiongdaoensis seedlings

BMC Genomics, 2020
Background As air temperatures increase globally, more and more plants are exposed to heat-stress conditions. Although many studies have explored regulation networks in plants with the aim of improving their heat-stress tolerance, only few have revealed ...

Mycelial DNA persistence in a forest soil

Environmental DNA, 2021
Living fungi can be identified and monitored in their soil habitat using an array of molecular methods. However, DNA originating from dead fungal tissue may become stabilized in the soil and remain detectable for some time after cell death rendering ...
