Nutrient content and redistribution in leaves of Hevea brasiliensis and Pinus oocarpa /
Concentração e redistribuição de nutrientes em folhas de Hevea brasiliensis e Pinus oocarpa

open access: yesSemina: Ciências Agrárias, 2000
The content of macronutrients (N, P, K, Ca, Mg, and S) and nutrient redistribution were evaluated in leaves of two species, an 8 years old angiosperm (Hevea brasiliensis) and a 25 years old a gymnosperm (Pinus oocarpa), both cultivated on an eutrophic ...

Contributions of in situ hybridization of sRNA to the study on spatio-temporal gene expression in Hevea brasiliensis [PDF]

open access: yes, 2005
Since the dawn of the genomics era, much research has focused on functional studies of genes of interest. In situ hybridization is a method that can be used to precisely localize the expression of a gene in tissues and cells.

On language, (inter)disciplinarity, and collaboration with local scholars in Papua New Guinea environmental anthropology

open access: yesThe Australian Journal of Anthropology, EarlyView.
Abstract How can anthropologists ensure the accuracy of the statements they make in their publications, especially in an era of ever increasing budgetary and bureaucratic pressures that limit the duration of fieldwork? What should the role of language abilities be in this context and to what degree is it necessary to learn the language of the place ...

A review of the Mycrocylus ulei Ascomycetes fungus, causative agent of South American rubber-leaf blight Revisión sobre el hongo Microcyclus ulei, agente causal del mal suramericano de la hoja del caucho

open access: yesRevista Colombiana de Biotecnología, 2006
The Microcyclus ulei Ascomycetes fungus is the causal agent of south-American leaf blight (SALB), this being one of the most important diseases affecting the natural rubber tree (Hevea brasiliensis) in Latina-America and has been responsible for numerous

Some considerations concerning the panel management in rubber tapping (Hevea brasiliensis) [PDF]

open access: yes, 2006
Research devoted to long term panel management deserved less efforts, mainly due to the long duration required for experimentation. The present study deals with the comparison of two panel management strategies on nine clones tapped in 1/2S, over a total

Chloroplast Genomes of Croton alabamensis and Croton bonplandianus (Euphorbiaceae): Comparative Analysis With Related Croton Species

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Croton chloroplast genomes exhibit substantial structural diversity driven mainly by asymmetric inverted repeats (IRs) contraction and expansion, despite highly conserved gene content. IR boundary shifts predominantly involved the LSC region, indicating an LSC‐driven evolutionary pattern. The preliminary phylogenomic analyses confirmed the monophyly of

Potential of Agricultural Plantations and Orchards to Support Understory Forest Bird Diversity in Southeast Asia

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study assessed the potential of monoculture oil palm and rubber tree plantations, as well as polyculture orchards, to support understory bird diversity compared to forest reserves using mist‐netting. Orchards recorded the highest bird abundance and richness among agricultural lands, but all agricultural lands had less than half the understory bird
