Trees, tenure and conflict: Rubber in colonial Benin [PDF]

Journal of Development Economics, 2014
Tree crops have changed land tenure in Africa. Farmers have acquired permanent, alienable rights, but have also faced disputes with competing claimants and the state. Para rubber had many similar effects in the Benin region of colonial Nigeria. Farmers initially obtained land by traditional methods.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Winter tapping of cold-tolerant rubber clone Yunyan 77-4: a viable strategy to reschedule the production season and capture potential market premiums in China

Frontiers in Plant Science
Natural rubber production in China is constrained by a relatively cold climate, a short tapping season, and concentrated rainfall, leading to lower yields than that in tropical nations.

Impact of Chronosequence of Rubber Tree Plantations on Soil Microbial Activity

Journal of Pure and Applied Microbiology, 2018
Soil microorganisms play a central role in decomposition, nutrient mineralization, and nearly all ecological processes in a soil ecosystem. A number of soil microbiological parameters, notably microbial biomass carbon and basal respiration, have been ...

Ex Vitro Propagation of Rubber Tree (Hevea Brasiliensis) using Stem Cuttings [PDF]

, 2018
Stem cutting propagation preserves the genetic traits and leads to transfer of superior and genetically similar traits of parent plants to progenies. This method is also used to propagate recalcitrant, nonviable and difficult to germinateseeds.

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Opposing consensus science through scholarly practices: The role of claims maintenance

Journal of the Association for Information Science and Technology, EarlyView.
Abstract This study examines how three US‐based communities who oppose consensus science produce and disseminate scholarly‐like artifacts: pro‐life activists, Young Earth Creationists, and Anthropogenic Climate Crisis skeptics. Prior research shows that industry‐ or church‐backed advocacy campaigns often generate claims supported by these communities ...

Mitochondrial genome variation and intergenomic sequence transfers in Hevea species

Frontiers in Plant Science
Among the Hevea species, rubber tree (Hevea brasiliensis) is the most important source of natural rubber. In previous studies, we sequenced the complete nuclear and chloroplast genomes of Hevea species, providing an invaluable resource for studying their

Population genetic structure based on microsatellite markers in rubber tree (Hevea brasiliensis) germplasm collection : [P483] [PDF]

, 2014
Hevea brasiliensis is native to the Amazonian rain forest and an important source of natural rubber. All high-yielding cultivars of rubber tree in the world originated from breeding programs initially developed in Southeast Asia with a very narrow ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
