Spectral characterization of plant diversity in a biodiversity‐enriched oil palm plantation

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 199-210, April 2026.
How well can airborne imaging spectroscopy detect plant diversity in vertically complex agroforestry systems? We tested this in a biodiversity‐enriched oil palm plantation in Sumatra, Indonesia, using high‐resolution hyperspectral data. We calculated spectral alpha and beta diversity and compared them to field‐based plant diversity.

Screening natural oil palm (Elaeis guineensis Jacq.) populations using SSR markers [PDF]

, 2009
The assessment of genetic diversity and genetic structure of natural oil palm populations is carried out mostly for crop improvement purpose. A set of 16 microsatellite markers was used to genotype 494 palms from 49 populations belonging to ten African ...

Trophic Diversity in Aquatic Food Webs Along a Tropical Coastal River Continuum in West‐Central Africa

Freshwater Biology, Volume 71, Issue 4, April 2026.
ABSTRACT In the wet Afrotropics, information on trophic diversity and resource use in freshwaters is extremely limited. Here we used stable isotope ratios (δ13C, δ15N) from food webs along the continuum of a coastal river in the Republic of the Congo to examine seasonal and spatial patterns of trophic diversity.

The role of phenolic compounds in the determination of wilt disease tolerance of oil palm (Elaeis guineensis JACQ) [PDF]

, 2009
Oil palm defence reaction to the vascular wilt disease was characterized by the production of phenolic compounds in the roots and pseudobulbs infected at the prenursery stage.

Sensory Perception of Visually Impaired People Focused on Descriptive Sensory Analysis of Cosmetic Products

Journal of Sensory Studies, Volume 41, Issue 2, April 2026.
ABSTRACT Some researchers suggest visually impaired people's advantage in performing touch tests reflects not increased sensitivity, but the fact of being attentive to cues normally ignored by sighted people with regular vision or the more efficient use of sensory strategies.

Let there be light : light interception method update for oil palm (Elaeis guineensis Jacq.) canopies [PDF]

, 2018
Light interception (photosynthetically active radiation, PAR) experiments in oil palm (Elaeis guineensis Jacq.) plantations are scarce and often performed decennia ago, in Southeast Asia and without a clear methodology.

Data Mining for Simple Sequence Repeats in Oil Palm Expressed Sequence Tags [PDF]

, 2009
Expressed Sequence Tags or ESTs are small pieces of DNA sequence that are generated by sequencing either one or both ends of an expressed gene. ESTs provide researchers with a quick and inexpensive route for discovering new genes, for obtaining data on ...

Screening of Native Plant Species in the Artisanal Gold Mining Sites of Doko, Guinea: Perspectives for Phytoremediation

CLEAN – Soil, Air, Water, Volume 54, Issue 3, March 2026.
This study focuses on phytoremediation in a gold mining‐contaminated area in Doko, Guinea. Plant, soil, and rhizospheric soil samples were collected and subjected to physicochemical analyses to quantify heavy metal content. Biological indicators: bioconcentration factor (BCF), translocation factor (TF), and biological accumulation coefficient (BAC ...

Assessing labor productivity in the harvest of crops planted with Elaeis oleifera x Elaeis guineensis crossings in an oil palm plantation from Colombia☆

Oilseeds and fats, crops and lipids
In Colombia, crossings of Elaeis oleifera by Elaeis guineensis (OxG hybrids) were planted after Bud Rot outbreaks. These OxG hybrids had not been planted before, so management practices were adapted from those developed for Elaeis guineensis crops.
