[Effects of aerated irrigation on CO and NO emission from protected melon soils under different nitrogen application levels].

Ying Yong Sheng Tai Xue Bao 2019 Apr;30(4):1319-1326

Ministry of Education Key Laboratory of Agricultural Soil and Water Engineering in Arid and Semiarid Areas, Northwest A&F University, Yangling 712100, Shaanxi, China.

To reveal the effects of coupling nitrogen (N) application and aerated irrigation on soil CO and NO emission, and their relationship with soil temperature and moisture, an experiment was conducted in greenhouse melon fields by using the method of static chamber/gas chromatography to determine the CO and NO emissions of different nitrogen rates under aerated irrigation. There were two irrigation factors (AI: aerated irrigation; CK: conventional irrigation) and three N levels (N: 0; N: 150 kg·hm, the traditional nitrogen application rate was 2/3; N: 225 kg·hm, traditional nitrogen application rate). The results showed that soil CO and NO emissions in AI treatment were higher than those in CK, but no significant difference was observed between the two irrigation methods. Read More

Toxicological effects of toxic metals (cadmium and mercury) on blood and the thyroid gland and pharmacological intervention by vitamin C in rabbits.

Environ Sci Pollut Res Int 2019 Apr 16. Epub 2019 Apr 16.

Department of Zoology, University of the Punjab, Lahore, Pakistan.

Cadmium and mercury are non-biodegradable toxic metals that may cause many detrimental effects to the thyroid gland and blood. Vitamin C has been found to be a significant chain-breaking antioxidant and enzyme co-factor against metal toxicity and thus make them less available for animals. The current study was performed to find the effect of individual metals (cadmium and mercury), their co-administration, and the ameliorative effects of vitamin C on some of the parameters that indicate oxidative stress and thyroid dysfunction.

Tracking temporal shifts in area, biomes, and pollinators in the radiation of Salvia (sages) across continents: leveraging anchored hybrid enrichment and targeted sequence data.

Am J Bot 2019 Apr 15. Epub 2019 Apr 15.

Department of Botany, University of Wisconsin-Madison, Madison, WI, 53706, USA.

Premise Of The Study: A key question in evolutionary biology is why some clades are more successful by being widespread geographically, biome diverse, or species-rich. To extend understanding of how shifts in area, biomes, and pollinators impact diversification in plants, we examined the relationships of these shifts to diversification across the mega-genus Salvia.

Methods: A chronogram was developed from a supermatrix of anchored hybrid enrichment genomic data and targeted sequence data for over 500 of the nearly 1000 Salvia species. Read More

Unmanned Aerial Vehicle-Based Phenotyping Using Morphometric and Spectral Analysis Can Quantify Responses of Wild Tomato Plants to Salinity Stress.

Front Plant Sci 2019 29;10:370. Epub 2019 Mar 29.

Hydrology, Agriculture and Land Observation, Water Desalination and Reuse Center, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia.

With salt stress presenting a major threat to global food production, attention has turned to the identification and breeding of crop cultivars with improved salt tolerance. For instance, some accessions of wild species with higher salt tolerance than commercial varieties are being investigated for their potential to expand food production into marginal areas or to use brackish waters for irrigation. However, assessment of individual plant responses to salt stress in field trials is time-consuming, limiting, for example, longitudinal assessment of large numbers of plants. Read More

Plastic film mulching increased the accumulation and human health risks of phthalate esters in wheat grains.

Environ Pollut 2019 Mar 22;250:1-7. Epub 2019 Mar 22.

College of Natural Resources and Environment, Northwest A&F University, No.3 Taicheng Road, Yangling, 712100, Shaanxi, China; State Key Laboratory of Crop Stress Biology for Arid Areas, Northwest A&F University, Yangling, 712100, Shaanxi, China.

Plastic film mulching is a common practice to increase crop yield in dryland, while the wide use of plastic film has resulted in ubiquitous phthalate esters (PAEs) releasing into the soil. PAEs in soil could be taken up and accumulated by dietary intake of food crops such as wheat, thus imposing health risks to residents. In the present study, samples from a long-term location-fixed field experiment were examined to clarify the accumulation of PAEs in soil and wheat, and to assess the human health risks from PAEs via dietary intake of wheat grain under plastic film mulching cultivation in dryland.

Evolutionary agroecology: Trends in root architecture during wheat breeding.

Evol Appl 2019 Apr 26;12(4):733-743. Epub 2018 Dec 26.

State Key Laboratory of Grassland Agro-ecosystems, Institute of Arid Agroecology, School of Life Sciences Lanzhou University Lanzhou Gansu Province China.

Root system characteristics determine soil space exploration and resource acquisition, and these characteristics include competitive traits that increase individual fitness but reduce population performance. We hypothesize that crop breeding for increased yield is often a form of "group selection" that reduces such "selfish" traits to increase population yield. To study trends in root architecture resulting from plant breeding and test the hypothesis that increased yields result in part from group selection on root traits, we investigated root growth and branching behavior in a historical sequence of wheat () cultivars that have been widely grown in northwestern China.

Improving Illumina assemblies with Hi-C and long reads: an example with the North African dromedary.

Mol Ecol Resour 2019 Apr 11. Epub 2019 Apr 11.

Research Institute of Wildlife Ecology, Department of Integrative Biology and Evolution, Vetmeduni Vienna, Vienna, Austria.

Researchers have assembled thousands of eukaryotic genomes using Illumina reads, but traditional mate-pair libraries cannot span all repetitive elements, resulting in highly fragmented assemblies. However, both chromosome conformation capture techniques, such as Hi-C and Dovetail Genomics Chicago libraries and long-read sequencing, such as Pacific Biosciences and Oxford Nanopore, help span and resolve repetitive regions and therefore improve genome assemblies. One important livestock species of arid regions that does not have a high-quality contiguous reference genome is the dromedary (Camelus dromedarius). Read More

Hierarchical distance sampling to estimate population sizes of common lizards across a desert ecoregion.

Ecol Evol 2019 Mar 20;9(6):3046-3058. Epub 2019 Feb 20.

Center for Conservation Biology University of California Riverside Riverside California.

Multispecies wildlife monitoring across large geographical regions is important for effective conservation planning in response to expected impacts from climate change and land use. Unlike many species of birds, mammals, and amphibians which can be efficiently sampled using automated sensors including cameras and sound recorders, reptiles are often much more challenging to detect, in part because of their typically cryptic behavior and generally small body sizes. Although many lizard species are more active during the day which makes them easier to detect using visual encounter surveys, they may be unavailable for sampling during certain periods of the day or year due to their sensitivity to temperature.
