“…Gorman, Handrigan, Jin, Wallis, and Breden (2010) studied spinal curvature in an inbreeded curveback guppy (Poecilia reticulate) lineage, and suggested that changes in vertebra bone structure associated with spinal curvature may be due to distortion of normal vertebra shape, or active remodelling of vertebra osteoid bone as a consequence of extrinsic forces. There are many reports of lordosis in wild fish (Ayed et al, 2008;Da Cunha & Antunes, 1999;Jawad, Al-Faisal, & Al-Mutlak, 2014;Jawad & Liu, 2015;Jawad & Öktener, 2007), but this is the first record in a wild gadoid, and also the first record in a wild animal in Norway. In specimen 6, some of the un-deformed vertebra had an elongated appearance.…”

This study describes radiological malformations in the vertebral column of adult sexually mature wild haddock, Melanogrammus aeglefinus collected from Masfjorden, Western Norway, in 2014 and 2015. There were seven deformed fish (33% of sampled fish), five with mild deformities and two with severe deformities. The deformity types discovered were lordosis, vertebra body asymmetry, compression, fusion (ankylosis), remodelling, and haemal spine hyperostosis. The two severely deformed fish were as follows: (a) one specimen with 29 deformed vertebrae within the region vertebrae nos. 1–30, including two sites of lordosis; (b) one specimen with 15 deformed vertebrae within the region vertebrae nos. 31–52 (most caudal vertebrae). The results of this study show that wild haddock can survive severe vertebra deformities, both in the trunk and tail region, and reach adulthood and sexual maturity. Whether normal nondeformed wild conspecifics would mate and spawn with these individuals and thereby complete the life cycle of the deformed individuals is, however, unknown. A possible link between bone fracture and fish hyperostosis is discussed.

“…Within the many levels of investigation supporting the use of fish as bioindicators of environmental degradation (see [29] for a review), morphological anomalies and skeletal anomalies in fish have been proposed [47][48][49] as potential easily detectable indicators of a disturbed development possibly related to environmental disturbance. Skeletal anomalies are taken into account in one of the first proposed multi-metric index based on fish fauna to evaluate anthropogenic pressures acting on water bodies, the Index of Biotic Integrity (IBI) [50].…”

Mediterranean coastal lagoons are increasingly affected by several threats, all concurrently leading to habitat degradation and loss. Methods based on fish for the assessment of the ecological status are under implementation for the Water Framework Directive requirements, to assess the overall quality of coastal lagoons. Complementary tools based on the use of single fish species as biological indicators could be useful as early detection methods of anthropogenic impacts. The analysis of skeletal anomalies in the big-scale sand smelt, Atherina boyeri, from nine Mediterranean coastal lagoons in Italy was carried out. Along with the morphological examination of fish, the environmental status of the nine lagoons was evaluated using a method based on expert judgement, by selecting and quantifying several environmental descriptors of direct and indirect human pressures acting on lagoon ecosystems. The average individual anomaly load and the frequency of individuals with severe anomalies allow to discriminate big-scale sand smelt samples on the basis of the site and of its quality status. Furthermore, a relationship between skeletal anomalies and the environmental quality of specific lagoons, driven by the anthropogenic pressures acting on them, was found. These findings support the potentiality of skeletal anomalies monitoring in big-scale sand smelt as a tool for early detection of anthropogenic impacts in coastal lagoons of the Mediterranean region.

“…Owing to these outstanding properties, aerogels are applied for thermal insulation, catalytic, and oil adsorption-desorption purposes. [3,4] Depending upon the affinity of aerogels toward water, they are classified as hydrophilic aerogels and hydrophobic aerogels. The hydrophilicity of aerogels is due to the presence of Si─OH groups DOI: 10.1002/masy.201800226 on the surface of aerogel.…”

The experimental result on the preparation of sodium silicate–based aerogels using a two‐step sol–gel process and ambient pressure drying is presented. The silica aerogels are prepared by following the procedure, namely, gel preparation, shaking of the gel in water and methanol, silylation/washing of the gel, and finally drying of the silylated gel at ambient pressure. The influence of various sol–gel and preparation parameters such as wt% of silica (2–6 wt%), NH4F:HCl molar ratios (0–0.5), and aging periods (0 to 24 h) on the physical and textural properties of the aerogels is studied. The physical properties such as bulk density, thermal conductivity, optical transmission, as well as the textural properties using BET analysis are studied. It is observed that the silica aerogels prepared using 3 wt% of silica, NH4F:HCl molar ratio of 0.333, and 3‐h aging period have low density ≈0.11 g cc–1, low thermal conductivity ≈0.12 W mK–1, as well as larger BJH (desorption) and BET surface areas of around 900 and 590 m2 g–1, respectively. The as‐synthesized aerogels have reduced processing period of 36 h and posses larger surface area. The as‐synthesized aerogels can be applied for thermal insulation purpose.
