Data from: Seeing spots: quantifying mother-offspring similarity and assessing fitness consequences of coat pattern traits in a wild population of giraffes (Giraffa camelopardalis)
Polymorphic phenotypes of mammalian coat coloration have been important to the study of genetics and evolution, but less is known about the inheritance and fitness consequences of individual variation in complex coat pattern traits such as spots and stripes. Giraffe coat markings are highly complex and variable and it has been hypothesized that variation in coat patterns most likely affects fitness by camouflaging neonates against visually hunting predators. We quantified complex coat pattern traits of wild Masai giraffes using image analysis software, determined the similarity of spot pattern traits between mother and offspring, and assessed whether variation in spot pattern traits was related to fitness as measured by juvenile survival. The methods we described could comprise a framework for objective quantification of complex mammal coat pattern traits based on photographic coat pattern data. We demonstrated that some characteristics of giraffe coat spot shape were likely to be heritable, as measured by mother-offspring regression. We found significant variation in juvenile survival among phenotypic groups of neonates defined by multivariate clustering based on spot trait measurement variables. We also found significant variation in neonatal survival associated with spot size and shape covariates. Larger spots (smaller number of spots) and irregularly shaped spots (smaller aspect ratio) were correlated with increased survival. These findings will inform investigations into developmental and genetic architecture of complex mammal coat patterns and their adaptive value.

Ductile, High-Lignin-Content Thermoset Films and Coatings
<p>Although lignin is a highly abundant and renewable polymer with very interesting properties, the preparation of high-lignin-content materials is challenging due to the brittleness and poor reactivity of lignin. Herein, high lignin content films and coatings were prepared by a simple and efficient method. A glyoxylic acid lignin (GA lignin), rich in carboxylic acid groups and hence highly reactive towards epoxy cross-linkers, was reacted with poly(ethylene glycol) diglycidyl ether and glycerol diglycidyl ether cross-linkers to achieve freestanding films containing up to 70 wt% lignin, and covalently attached surface coatings containing up to 90 wt% lignin. These films and coatings, potentially 100% biobased, show high antioxidant activity and UV barrier property, still maintaining good visible transparency. They hence are promising for application as sustainable food packaging films.</p>
The PERFECOAT Project – Bio-Based Ingredients for Paint and Coatings (Extented Version)
<p>Conventional paint contains many fossil-based ingredients. To mitigate the resulting effects of climate change, the PERFECOAT projects developed different bio-based ingredients like binders, pigments and functional nano materials to be tested in paint and coating formulations for wood and decorative applications. This video shows the objectives and achievements in an easy to understand visualized way. This is the extented version of the video including two interview sequences with PERFECOAT researchers. </p><p><a href="https://perfecoat-project.eu">https://perfecoat-project.eu</a></p>

A third pair of thinner, parallel stripes runs down the neck between the nuchal stripes, extending to about one fourth of the mid-dorsal line, where they vanish or diverge as the first row of flank spots. The black mid-dorsal line is continuous and is flanked on each side by four rows of oblong to squared spots, and by a few small-scattered spots below. There is a dorsal erectile crest. The face has a dark mask and a pair of white sub-ocular spots. The tail has seven to nine black rings, alternating with pale rings; the intervening white spaces are pigmented with a brownish tinge on the dorsal midline. The width of the pale rings relative to the dark rings in the middle of the tail is 50-75%; the tip of the tail is dark. The hindlimbs and forelimbs are black; there are white hairs on the metacarpals and metatarsals. [he posterior parts of the feet are dark. There are two pairs of teats.

Improving dryland seedling recruitment using fungicide seed coatings
<p>The success of seed-based restoration in dryland regions of the world is often low or sporadic, with most mortality occurring between germination and emergence. Fungal pathogenesis is one process that may reduce seedling emergence and limit restoration success.</p> <p>Our objective was to determine whether fungicide seed coatings constitute an economically viable strategy for increasing emergence by reducing fungal pathogenesis and mortality.</p> <p>We performed an experiment across two sites and three years, using bluebunch wheatgrass (Pseudoroegneria spicata) as a model species. We found that fungicide coatings increased germination by 8.8% and emergence by 54.0% on average compared to the control. A cost analysis indicated that the fungicide coating was economically viable with an average estimated effective cost reduction of 18.8% under the study conditions.</p> <p>There was a strong interaction (P < 0.001) between the effects of the fungicide coating, site, and year on emergence. The fungicide coating increased emergence compared to the control in five of the six sites and years, with the effect ranging from a 33.7% decrease (P = 0.042) to a 150.9% increase (P = 0.004).</p> <p>The observed interaction was likely related to the effect of the hydrothermal microsite environment on disease severity. In the site and year that the fungicide coating performed worse than the control, prolonged periods of exceptionally low soil moisture may have reduced disease severity through a variety of individual and community scale mechanisms.</p> <p>Overall, these results indicate that fungicide seed coatings have the potential to improve dryland restoration efforts.</p>

Data from: Shelf life and quality of tomato (Lycopersicon esculentum Mill.) fruits as affected by neem leaf extract dipping and beeswax coating
<p>The data was generated to investigate the effect of Beeswax (BW) coating and Neem leaf extract (NLE) dipping on the shelf life and quality of tomatoes (<em>Lycopersicon esculentum</em> Mill.) over a storage period of 36 days. A factorial combination of four levels of Neem plant extract (control, 15%, 20% and 25%) and four levels of beeswax coating (control, 3%, 6% and 9%) storage treatments with three replications were applied on fully matured green tomatoes in the study. The treatments were arranged in a randomized complete block design. The average storage room air temperature and relative humidity varied from 15.2 ºC to 20.4 ºC and 55.53% to 69.46% RH during 36 days of storage period at Haramaya University from February to April 2020. Data were recorded on 4, 8, 12, 16, 20, 24, 28, 32, and 36 days after storage. Data on physiological loss in weight, chemical compositions (total soluble solids, pH, titratable acidity, and ascorbic acid), decay (%), percentage marketability, and shelf life were assessed at an interval of four days during 36 days of storage period under ambient conditions.</p>
