Responses of agricultural weed community in a corn-soybean intercrop
This dataset was created as a part of an experiment which used a soybean-corn intercrop system for examining how the community structure of agricultural weeds changes with fertilization and with the identity of the crop species. The composition of the weed flora in intercrops was compared with the weed flora of the respective sole crops, with and without fertilization. The experiment was conducted at Kellogg Biological Station (KBS) in southwestern Michigan, USA, in 1993.

Data from: Effect of storage condition on the physicochemical properties of corn-wheat starch / zein edible bilayer films
<p>The functional properties of biopolymer-based film packaging materials are susceptible to external storage conditions. The effects of different storage temperature, relative humidity (RH) and duration on the apparent form, barrier properties, mechanical properties and microstructure of corn-wheat starch/zein bilayer films were studied. From 0 to 150 d, storage temperature and RH, but not storage time, affected the appearance and colour of the bilayer films. The increase in haze of the bilayer films stored at 25°C was much greater than that at low temperatures. With increased storage time, the moisture content first increased and then decreased, while the water resistance and oxygen barrier properties of the bilayer films worsened. After 150 d, the bilayer film stored at 25°C with 54% RH had better water resistance properties. The oxygen barrier properties of the bilayer film stored at 25°C with 43% RH were preferable to those of other groups because the peroxide value of vegetable oil packed in the former bilayer film was the lowest. The tensile strength of bilayer films stored at 25°C with RH of 43%, 54%, and 65% decreased, but were still better than those stored at low temperatures (-17°C, 4°C), which were tough due to their high elongation at break. SEM results showed tight bonds between the bilayer films, and the network structure inside the films disappeared and reappeared during storage. The cross-sectional compactness changed, and there was no film separation after 150 d.</p>
Data from: Introgression between divergent corn borer species in a region of sympatry: implications on the evolution and adaptation of pest arthropods
The Asian corn borer, Ostrinia furnacalis, and European corn borer, O. nubilalis (Lepidoptera: Crambidae), cause damage to cultivated maize in spatially distinct geographies, and have evolved divergent hydrocarbons as the basis of sexual communication. The Yili area of Xinjiang Uyghur Autonomous Region in China represents the only known region where O. furnacalis has invaded a native O. nubilalis range, and these two corn borer species have made secondary contact. Genetic differentiation was estimated between Ostrinia larvae collected from maize plants at 11 locations in Xinjiang Province, and genotyped using high throughput SNP and microsatellite markers. Maternal lineages were assessed by direct sequencing of mitochondrial cytochrome c oxidase subunit I and II haplotypes, and a high degree of genotypic diversity was demonstrated between lineages based on SNP genotypes. Furthermore, historical introgression was predicted among SNP genotypes only at sympatric locations in the Yili area, whereas in Xinjiang populations wherein only O. furnacalis haplotypes were detected no analogous introgressed genotypes were predicted. Our detection of putative hybrids and historical evidence of introgression defines Yili area as a hybrid zone between the species in normal ecological interactions, and furthermore might indicate that adaptive traits could spread even between seemingly divergent species through horizontal transmission. Results of this study indicate there may be a continuum in the degree of reproductive isolation between Ostrinia species, and that the elegance of distinct and complete speciation based on modifications to the pheromone communication might need to be reconsidered.
Data from: Microbial composition play the leading role in volatile fatty acid production in the fermentation of different scale of corn stover with rumen fluid
<p>Rumen fluid is a natural and green biocatalyst that can efficiently degrade biomass into volatile fatty acid (VFA) used to produce value-added materials. But the essence of high degradation efficiency in the rumen has not been fully analyzed. This study investigated the contribution of substrate structure and microbial composition to volatile fatty acid production in the fermentation of corn stover. The ball milled corn stover were innovatively applied to ferment with the rumen fluid collected at different digestion times. Exogeneous cellulase was also added to the ruminal fermentation to further reveal the inner mechanism. With prolonged digestion time, the microbial community relative abundance levels of Bacteroidetes and Firmicutes increased from 29.98% to 72.74% and decreased from 51.76% to 22.11%, respectively. The highest VFA production of the corn stover was achieved via treatment with the rumen fluid collected at 24 h which was up to 9508 mg/L. The ball milled corn stover achieved high VFA production because of the more accessible substrate structure. The application of exogenous cellulase has no significant influence to the ruminal fermentation. The microbial community abundance contributed more to the VFA production compared with the substrate structures.</p>

Corn Springs Miners Cabin
Corn Springs Miners Cabin Corn Springs Cabin is located near Desert Center California. Corn Springs Mining District was established in 1897. Miners came to the area and used the water for processing their gold ore, in the late 19th century. The most notable resident of the spring was Gus Lederer. The self-proclaimed "Mayor of Corn Springs", was Gus Lederer. He lived at the spring until 1932, when he died from a black widow spider bite. There is a Bureau of Land Management (BLM) campground nearby and Chemehuevi, Desert Cahuilla and Yuma bands carved elaborate petroglyphs in the nearby rocks. In 1998, the springs were added to the United States National Register of Historic Places. This 3D model was created in Pix4D merging double grid and orbits. Mavic Pro 2.

Data to accompany from: Effects of neonicotinoid seed treatments on wildbee populations and soybean and corn fields in eastern Ontario
<p><span>Neonicotinoid-coated corn and soybean seeds are a common crop in Canada and the US. A growing body of research is demonstrating that, through various exposure routes, neonicotinoids can impact a suite of non-target organisms including beneficial insects such as bees. However, to date, only a few studies have examined the effects of neonicotinoids in field settings. We assessed the relationship between agricultural crop soil neonicotinoid levels and wild bee abundance and diversity at 16 agricultural sites representing different soil neonicotinoid levels. We detected clothianidin at 11 sites, thiamethoxam at three sites; imidacloprid was not detected. Hedgerow and crop soils were consistent in terms of where clothianidin was detected; thiamethoxan was not detected in hedgerow soils. Based on model outcomes, fields with higher levels of soil neonicotinoids exhibited significantly lower wild bee abundance and diversity than those with low or no neonicotinoids detected. Crop soil neonicotinoid level, hedgerow floral resource abundance and crop type were consistent predictors of bee abundance across models; only neonicotinoid level and crop type were significant predictors of diversity. Our results are consistent with recent findings in the midwestern US, and underscore the potential risk of soil neonicotinoids to wild bee populations across regions and crop systems.</span></p>
Elevated temperature increases reproductive investment in less preferred mates in the invasive European corn borer moth
<p>Rapidly changing environments may weaken sexual selection and lead to indiscriminate mating by interfering with the reception of mating signals or by increasing the costs associated with mate choice. If temperature alters sexual selection, it may impact population response and adaptation to climate change. Here, we examine how differences in temperature of the mating environment influence reproductive investment in the European corn borer moth (<i>Ostrinia nubilalis</i>). Mate preference in this species is known to be related to pheromone usage, with assortative mating occurring between genetically distinct E- and Z-strains that differ in the composition of female and male pheromones. We compared egg production within and between corn borer lines derived from four different populations that vary in pheromone composition and other traits. Pairs of adults were placed in a mating environment that matched the pupal environment (ambient temperature) or at elevated temperature (5ºC above the pupal environment). At ambient temperature, we found that within-line pairs produced eggs sooner and produced more egg clusters than between-line pairs. However, at elevated temperature, between-line pairs produced the same number of egg clusters as within-line pairs. These results suggest that elevated temperature increased investment in matings with typically less preferred, between-line mates. This increased investment could result in changes in gene flow among corn borer populations in warming environments.</p>

Kõtkõra asisi 'Kõtkõra's corn' or 'The origin of maize and other crops among the Sakurabiat people'
<p>This short narrative is a fragment of a mythological tale that describes the origin<br> of maize and other crops, such as beans and manioc (yucca), among the Sakurabiat people. Sakurabiat is pronounced [sa’kɨrabiat]. In the orthographic convention for the language the grapheme <u> represents the hight central vowel<br> [ɨ].The Sakurabiat are very reduced in number. In the last survey done in 2016,<br> there were only 65 people living in the Rio Mekens Indigenous Land.<br> The Kõtkõra asisi story is told by Mercedes Guaratira Sakyrabiar, one of the<br> oldest speakers of Sakurabiat at the time of the recording. Sadly, she passed away<br> in December of 2015. Mercedes’s age was not known for certain, but she was<br> believed to be more than 75 years old when she told this story in 2006. The story<br> was recorded in audio as part of a long term project for the documentation and<br> study of the Sakurabiat (Mekens) language, which had partial support from the<br> Endangered Language Documentation Program, funded by the School of Oriental<br> and African Studies (SOAS).</p> <p> </p> <p> </p> <p>This dataset contains the mediafiles.
