Effect of Temperature and Light on Ex Situ Germination of Flemingia faginea (Guill. & Perr.) Baker Seeds in Burkina Faso

open access: yesInternational Journal of Forestry Research
Flemingia faginea is a woody species whose various parts are widely used in traditional medicine. However, this species, which typically grows along waterways, is becoming increasingly rare due to poor seed germination in the wild, possibly resulting ...

Harnessing Microbial Agents to Improve Soil Health and Rice Yield Under Straw Return in Rice–Wheat Agroecosystems

open access: yesAgriculture
We clarified the effect of wheat straw return combined with microbial agents on rice yield and soil properties. A field experiment was conducted using hybrid indica rice ‘Chuankangyou 2115’ and five treatments: no wheat straw return (T1), wheat straw ...

Bridging the gap between omics and earth system science to better understand how environmental change impacts marine microbes [PDF]

open access: yes, 2015
The advent of genomic-, transcriptomic- and proteomic-based approaches has revolutionized our ability to describe marine microbial communities, including biogeography, metabolic potential and diversity, mechanisms of adaptation, and phylogeny and ...

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments

open access: yesJournal of Fish Biology, EarlyView.
Abstract The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion‐poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO2 levels (hypoxia and hyperoxia), high PCO2 levels (hypercapnia), high ...

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Species delimitation within the Achnanthidium minutissimum complex (Bacillariophyta), based on morphological, molecular, and ecophysiological approaches

open access: yesJournal of Phycology, EarlyView.
Abstract The benthic diatom species Achnanthidium minutissimum belongs to a species complex with a challenging taxonomy. Achnanthidium minutissimum has been reported to be a widespread and abundant species occurring in a broad range of freshwater habitats. However, differentiating and delimiting it from other Achnanthidium species is challenging due to

Imbalance Water Deficit Improves the Seed Yield and Quality of Soybean

open access: yesAgronomy, 2018
Water imbalance condition (WIC) in a maize-soybean relay intercropping system is the main abiotic stress limiting biomass production and seed yield and, consequently, seed-quality.
