Etude de la régénération naturelle du Symphonia globuliferades forêts humides togolaises au Togo

Journal of Agriculture and Environment for International Development, 2013
Une étude a été menée dans la forêt classée de Missahoé et ses environs en vue d’apprécier la régénération naturelle de Symphonia globulifera. La collecte des données à cette fin a été réalisée sur une dizaine de parcelles.

Potential pollinators of understory populations of Symphonia globulifera in the Neotropics.

Journal of Pollination Ecology, 2018
One difference between the forest canopy and the understory is that animals pollinate the majority of understory species in the tropical wet forest. Pollinators active in the understory are also different from those in the forest canopy and are adapted ...

Floristic composition and turnover analysis in Dahomey Gap and the surrounding sub-humid Togolese mountain minor forest refuges: Importance for biogeography and biodiversity conservation in sub-Saharan Africa. [PDF]

Ecol Evol, 2022
The origin of the DG is one of the central biogeographical questions in sub‐Saharan Africa, which has been addressed in recent phylogenetic studies. Till date, no study based on large floristic data collected in the DG has addressed this question. Our work, based on large floristic data collected in the DG and compared with those of regional floras, is

Widespread introduced species dominate the urban tree assemblage on the endemic-rich tropical island of São Tomé. [PDF]

Ecol Evol
Afrotropical cities are growing rapidly but how this impacts biodiversity is largely unclear. Our study on São Tomé Island, Central Africa, reveals that the urban tree assemblage is impoverished and dominated by introduced species, while the natural forest is essential for the protection of native and endemic species.

Unlocking Tropical Forest Complexity: How Tree Assemblages in Secondary Forests Boost Biodiversity Conservation. [PDF]

Ecol Evol
Secondary forests are crucial for achieving COP15/16 conservation goals. An operational national approach was developed to identify and characterise forest ecosystems based on the dominant tree species in the canopy, serving as indicators for ecosystem extent and condition.

Methane emissions from tree stems in neotropical peatlands. [PDF]

New Phytol, 2020
Summary Neotropical peatlands emit large amounts of methane (CH4) from the soil surface, but fluxes from tree stems in these ecosystems are unknown. In this study we investigated CH4 emissions from five tree species in two forest types common to neotropical lowland peatlands in Panama.

Altitudinal gradients, biogeographic history and microhabitat adaptation affect fine-scale spatial genetic structure in African and Neotropical populations of an ancient tropical tree species. [PDF]

PLoS ONE, 2017
The analysis of fine-scale spatial genetic structure (FSGS) within populations can provide insights into eco-evolutionary processes. Restricted dispersal and locally occurring genetic drift are the primary causes for FSGS at equilibrium, as described in ...

When can we detect lianas from space? Toward a mechanistic understanding of liana-infested forest optics. [PDF]

Ecology
Abstract Lianas, woody vines acting as structural parasites of trees, have profound effects on the composition and structure of tropical forests, impacting tree growth, mortality, and forest succession. Remote sensing could offer a powerful tool for quantifying the scale of liana infestation, provided the availability of robust detection methods.

Globulixanthone F, a New Polyoxygenated Xanthone with an Isoprenoid Group and Two Antimicrobial Biflavonoids from the Stem Bark of [PDF]

Natural Product Communications, 2009
Bioassay-guided fractionation of the stem bark of Symphonia globulifera has yielded three known xanthones, ugaxanthone (1), mbarraxanthone (2) and gentisein (3), two biflavonoid derivatives named GB2 (4) and manniflavanone GB3 (5), and one new ...

Flora of Ceará, Brazil: Clusiaceae [PDF]

Rodriguésia, 2023
The floristic-taxonomic survey of Clusiaceae is presented as part of the project “Flora of Ceará: knowing to conserve”. The study was based on the analysis of specimens deposited in national and international herbaria and observations of natural ...
