The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

open access: yesAdvanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Fixing tropical forests

open access: yesNature Ecology & Evolution, 2018
An extensive dataset indicates that nitrogen-fixing trees are most abundant in young, dry tropical forests. The finding expands the potential for natural nitrogen fertilization and carbon dioxide sequestration in areas recovering from land use.

A Modular PLUG‐IN Photosynthetic Chassis With Tunable Thermal Control for Mammalian Systems

open access: yesAdvanced Science, EarlyView.
This work establishes a “plug‐in” chassis compatible with mammalian systems that synchronizes growth, production, and cell‐wall re‐configuration, providing a versatile platform for photosynthetic bioproduction and microalgal synthetic biology. ABSTRACT Microalgae are promising photosynthetic platforms for high‐value compounds, yet their industrial use ...

Tropical Forest Regeneration

open access: yes, 2013
Following large-scale human or natural disturbances, the regeneration of tropical forests follows a progression of stages through which forest assemblages gradually become enriched with species and increase in structural and functional complexity. Successional pathways and rates of change vary widely according to the nature of prior land use, the ...

Do outgrower schemes enhance technology adoption and productivity? Evidence from maize farmers in Northern Ghana

open access: yesAgribusiness, EarlyView.
Abstract Nucleus outgrower schemes are contractual arrangements where well‐resourced large‐scale farmers (nucleus farmers) are empowered by development support agencies to take charge of smallholder farmers, by providing them with market access and the necessary training on agronomic practices and farm inputs for production.

Responses of leaf-litter ant communities to tropical forest wildfires vary with season [PDF]

open access: yes, 2012
Fire is an important land-management tool in tropical forest landscapes. However, these fires sometimes escape into surrounding forests (Uhl & Buschbacker 1985), and are one of the most severe disturbances threatening tropical forest biodiversity (Barlow

The impact of forest management on saproxylic beetles and other arthropods in a semi-deciduous forest in Southern Benin [PDF]

open access: yes, 2004
Tropical forest ecosystems worldwide are suffering from anthropogenic pressures leading to deforestation and forest degradation, and resulting in a loss of biodiversity.

Factorization Machine‐Based Active Learning for Functional Materials Design with Optimal Initial Data

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work investigates the optimal initial data size for surrogate‐based active learning in functional material optimization. Using factorization machine (FM)‐based quadratic unconstrained binary optimization (QUBO) surrogates and averaged piecewise linear regression, we show that adequate initial data accelerates convergence, enhances efficiency, and ...

Energy and water dynamics of a central Amazonian rain forest [PDF]

open access: yes, 2002
This paper presents measurements of the energy and water budgets of a tropical rain forest near Manaus, Brazil, in central Amazonia, collected between September 1995 and August 1996.

Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...
