Abstract:
Visual camouflage is a textbook example of natural selection, and a widespread strategy used by both predators and prey to avoid detection. Background matching, where the animal resembles the colour, brightness, and/ or pattern of the surrounding visual background is a common form of visual camouflage, and can occur through genetic polymorphism, behavioural background choice, or dynamic colour change. Dynamic colour change can occur very rapidly (milliseconds) or gradually, sometimes taking weeks to complete. Visual cues such as colour, brightness, and pattern, have been shown to elicit colour change, and in some colour-changing animals visual cues are sensed outside of the eye using extraocular photoreceptors (EOPs). Colour change research has been focused predominantly on rapid, chromatophore-based colour change, as observed in cephalopods. In contrast, little is known about the physiology and evolutionary origins of gradual colour change. To avoid predation in a wide range of environments, caterpillars of the peppered moth (Biston betularia) masquerade as twigs and gradually change colour to match them. This thesis investigates the colour-changing response in B. betularia larvae: the shape of the reaction norm to colour and brightness gradients; the use and molecular basis of extraocular photoreception; and whether B. betularia alter resting behaviour to maximise concealment. Through a series of artificial twig experiments, I found that B. betularia larvae respond to both colour and luminance cues to produce a continuous range of phenotypes, rather than being restricted to a brown/green polyphenism as previously reported. To test for the possibility of extraocular photoreception, I occluded the eyes (ocelli) of groups of larvae and compared responses to colour and luminance with non-blindfolded control larvae. There was no difference in the colour-changing response of blindfolded larvae compared to controls, and blindfolded larvae also rested on colours that better matched their own colour to the same extent as non-blindfolded controls. I next examined the potential for visual machinery in the larval dermis, finding expression of a suite of visual genes throughout dermal tissue in B. betularia larvae and adults. In larvae, this expression was generally much higher relative to head tissue than found for adults. This finding corroborates the morphological and behavioural evidence for dermal photoreceptors in B. betularia larvae. The final chapter is an attempt to examine the exclusivity of extraocular photoreception in B. betularia, and its evolutionary origins, through tissue-specific measurement of opsin expression in larvae and adults of a phylogenetically broad sample of Lepidoptera. Dermal opsin expression was found in other species, but depended on the gene (UV, blue, LW1, LW2) and developmental stage. Phylogenetic signal was found only for expression of LW1 in larvae, and LW2 in adults. Larval colouration strategy between species also appears to affect dermal opsin expression. The thesis provides strong evidence for a novel physiological phenomenon: extraocular colour photoreception in the dermis of an insect, used to mediate colour change and behavioural background choice. The observation that dermal opsin expression occurs in several other species suggests that EOPs may be widespread in the Lepidoptera. Future work should be directed at the challenging task of understanding the mechanism underlying this class of EOPs, and characterising their functional roles in other species.

Abstract:
Organisms seem exquisitely adapted—like the peppered moths (Biston betularia), camouflaged to avoid predation (Figure 20.1). The story behind their cryptic coloration and pattern is easy to appreciate when looking at both black and mottled white moths set against contrasting backgrounds: one black, one mottled white, like the moths themselves. What half-witted bird would not prey on the obvious moth? This would clearly change the genetic make-up of a population. This popular pair of photos explains natural selection in an instant. The images are so widely reproduced, in biology textbooks and elsewhere, that everyone seems to know the case of the peppered moth. The case gained renown through Bernard Kettlewell. In the 1950s he investigated the survival rates of the moths in the contrasting forests of Birmingham and Dorset (ostensibly portrayed in Figure 20.1). But Kettlewell’s landmark publication, The Evolution of Melanism, also included another image (Figure 20.2). On the top right, it displays the two familiar forms of the moth: typica, the once-common “peppered” form (no. 2), and carbonaria, the nearly black form that proliferated later (no. 1). Arrayed on the left, however, are five other specimens of the same species, each exhibiting an intermediate darkness. Together, they constitute a third form, known as insularia. That is, a series of relatively unknown light and dark forms fills the gap between the two well-known extremes. Do the insularia moths matter? How might simplifying the wide range of forms to just two shape an image of natural selection? Or of nature, generally? In what ways does the difference between the simple story and a more complex reality ultimately affect our thinking? Perhaps we should challenge the implicit assumption (yet another sacred bovine) that nature, and science too, can effectively be reduced to black and white. One easily finds specimens of insularia in museum collections, Kettlewell noted. And he included them in his field studies. Having recruited observers from around Britain, Kettlewell catalogued the relative frequencies of all three forms in various locations. The incidence of insularia was sometimes 40% or more.

Abstract:
Chapter 5 explores literary texts which develop postgenomic perspectives. Margaret Drabble’s novel-memoir The Peppered Moth mobilizes neo-Lamarckian theories to challenge neo-Darwinian views of inheritance. In tracing the experience of social defeat and its impact across generations, it invokes a process close to transgenerational epigenetic inheritance, opening up questions about the biological transmission of social disadvantage. Jackie Kay’s memoir Red Dust Road also pushes against the limits of neo-Darwinian theory, demonstrating that nurture as well as nature can be somatically inscribed, anticipating research in epigenetics which demonstrates that experience can act as a cue for the modification of gene expression. It contrasts the love Kay receives in early life, which builds an enduring resilience, with the experience of racism associated with her brother’s adoption, which generates lasting insecurity. Catherine Malabou’s work on positive and negative plasticity illuminates these divergent trajectories.

Abstract:
Hot Water Treatment (HWT) provides adequate phytosanitary assurance that treated fruits and vegetables exported abroad are free from devastating quarantine pests. Two systems for HWT are currently available for commercial use namely the batch/jacuzzi and the continuous flow system depending on user requirements. Several protocols have been developed the world over and a few in Africa, but adoption has been lagging because of various factors chief among them lack of large scale validations of experiments to guide application at the commercial level. Mango, Bell pepper, avocado, and French beans play an important role in the livelihoods of people in Africa. However, their export is constrained by pests such as the invasive Oriental fruit fly, the false codling moth, and thrips. To circumvent this issue, disinfestation HWT protocols have been developed which seek to provide quarantine assurance to lucrative export markets. Hot Water Treatment technology has several advantages over other conventional phytosanitary treatments. It provides a triple function of cleaning, disinfesting, and disinfecting and is friendly to users, consumers of the treated commodities, and the environment. We discuss HWT in the context of its future and applicability in Africa. It is the future of postharvest treatments.

With his debut album rapidly ascending the British record charts, Jimi gives a series of revealing interviews in advance of the Experience’s much-anticipated final U.K. show at the Saville Theatre. During this performance, the band stuns Paul McCartney by opening with a cover of the Beatles’ just-released Sgt. Pepper’s Lonely Hearts Club Band. After a series of photoshoots, the Experience flies to New York City in advance of their performance at the Monterey International Pop Festival. Jimi revisits the New York City haunts he’d left behind just nine month earlier. Upon their arrival in Monterey, California, Jimi hand-paints the Stratocaster he’ll use to climax their set. The weekend-long Monterey festival presents a wide array of rock talent and climaxes with the sets by The Who and Jimi Hendrix. Jimi stuns the audience, most of whom have never heard of him, with his charismatic personality and unprecedented approach to performing. He ends the Experience’s set by burning his guitar amid a roaring cacophony of feedback. As Joel Selvin sagely noted, Jimi Hendrix “walked onstage a nobody and walked off a major star, ready to rewrite the language of the guitar.”

Abstract:
Diseases caused by Colletotrichum spp. are one of the most important limitations on international strawberry production, affecting all vegetative and fruiting parts of the plant. From 1995 to 1997, C. acutatum infections reached epidemic levels in Israeli strawberry nurseries, causing extensive loss of transplants in fruit-bearing fields and additional reductions in yield. Although C. acutatum also occurs on strawberry in Florida, recent crown rot epidemics have been primarily caused by C. gloeosporioides. Little is known about the basic epidemiology of these important diseases on strawberry. The source of initial inoculum for epidemics in Israel, Florida (other US states including California) and the rest of the world is not well understood. Subspecies relationships between Colletotrichum isolates that cause the different diseases on strawberry (i.e. attack different tissues) are also not well understood. Objectives of this proposal were to detennine the potential of infested soil, strawberry debris and other hosts as sources of primary inoculum for strawberry diseases caused by Colletotrichum spp. in Israel and Florida. In addition, traditional (ie. morphological characteristics, benomyl sensitivity, vegetative compatibility grouping) and DNA based methods were used to investigate the etiology of these diseases in order to resolve epidemiologically important subspecies variation. In Israel it was found that C. gloeosporioides and C. acutatum infecting strawberry could remain viable in sterilized soil for up to one year and in methyl-bromide fumigated soil for up to 4 months; inoculum in mummified fruit remained viable for at least 5 months under field conditions whereas that in infected crowns was not recovered. Therefore, the contribution of these inocula to disease epidemics should be considered. The host range and specificity of C. acutatum from strawberry was examined on pepper, eggplant, tomato, bean and strawberry under greenhouse conditions. The fungus was recovered from all plant species over a three-month period but caused disease symptoms only on strawberry. C. acutatum was also isolated from healthy looking, asymptomatic plants of the weed species, Vicia and Conyza, growing in infected strawberry fruiting fields. Isolates of C. acutatum originating from strawberry and anemone infected both plant species in artificial inoculations. The habitation of a large number of plant species including weeds by C. acutatum suggests that although it causes disease only on strawberry and anemone in Israel, these plants may serve as a potential inoculum source for strawberry infection and pennit survival of the pathogen between seasons. In Florida, isolates of Colletotrichum spp. from diseased strawberry fruit and crowns were evaluated to detennine their etiology and the genetic diversity of the pathogens. Only C. acutatum was recovered from fruit and C. gloeosporioides were the main species recovered from crowns. These isolates were evaluated at 40 putative genetic loci using random amplified polymorphic DNA (RAPD). Genetic analysis of RAPD markers revealed that the level of linkage disequilibrium among polymorphic loci in C. gloeosporioides suggested that they were a sexually reproducing population. Under field conditions in Florida, it was detennined that C. gloeosporioides in buried crowns survived

Abstract:
COVID-19, caused by the SARS-CoV-2 virus, was first reported in China in December 2019. The virus has spread rapidly around the world and is currently responsible for 500 million reported cases and over 6.4 million deaths. A risk assessment published by the Foods Standards Agency (FSA) in 2020 (Opens in a new window) concluded that it was very unlikely that you could catch coronavirus via food. This assessment included the worst-case assumption that, if food became contaminated during production, no significant inactivation of virus would occur before consumption. However, the rate of inactivation of virus on products sold at various temperatures was identified as a key uncertainty, because if inactivation does occur more rapidly in some situations, then a lower risk may be more appropriate. This project was commissioned to measure the rate of inactivation of virus on the surface of various types of food and food packaging, reducing that uncertainty. The results will be used to consider whether the assumption currently made in the risk assessment remains appropriate for food kept at a range of temperatures, or whether a lower risk is more appropriate for some. We conducted a laboratory-based study, artificially contaminating infectious SARS-CoV-2 virus onto the surfaces of foods and food packaging. We measured how the amount of infectious virus present on those surfaces declined over time, at a range of temperatures and relative humidity levels, reflecting typical storage conditions. We tested broccoli, peppers, apple, raspberry, cheddar cheese, sliced ham, olives, brine from the olives, white and brown bread crusts, croissants and pain au chocolat. The foods tested were selected as they are commonly sold loose on supermarket shelves or uncovered at deli counters or market stalls, they may be difficult to wash, and they are often consumed without any further processing i.e. cooking. The food packaging materials tested were polyethylene terephthalate (PET1) trays and bottles; aluminium cans and composite drinks cartons. These were selected as they are the most commonly used food packaging materials or consumption of the product may involve direct mouth contact with the packaging. Results showed that virus survival varied depending on the foods and food packaging examined. In several cases, infectious virus was detected for several hours and in some cases for several days, under some conditions tested. For a highly infectious agent such as SARS-CoV-2, which is thought to be transmissible by touching contaminated surfaces and then the face, this confirmation is significant. For most foods tested there was a significant drop in levels of virus contamination over the first 24 hours. However, for cheddar cheese and sliced ham, stored in refrigerated conditions and a range of relative humidity, the virus levels remained high up to a week later, when the testing period was stopped. Both cheddar cheese and sliced ham have high moisture, protein and saturated fat content, possibly offering protection to the virus. When apples and olives were tested, the virus was inactivated to the limit of detection very quickly, within an hour, when the first time point was measured. We suggest that chemicals, such as flavonoids, present in the skin of apples and olives inactivate the virus. The rate of viral decrease was rapid, within a few hours, for croissants and pain au chocolat. These pastries are both coated with a liquid egg wash, which may have an inhibitory effect on the virus. Food packaging materials tested had variable virus survival. For all food packaging, there was a significant drop in levels of virus contamination over the first 24 hours, in all relative humidity conditions and at both 6°C and 21°C; these included PET1 bottles and trays, aluminium cans and composite drinks cartons.
