Esta tese examina as reações sociais ao processo de invasão biológica conduzido pelo javali asselvajado europeu (Sus scrofa) e seus cruzamentos com porcos domésticos, ou “javaporcos”, no Brasil Meridional desde um ponto de vista antropológico. Atualmente, esta espécie figura entre os cem piores organismos invasores do mundo conforme o painel sobre invasões biológicas da União Internacional para a Conservação da Natureza (IUCN, na sigla em inglês). Presente no Brasil desde o final da década de 1980, o javali tem provocado inúmeros danos ao meio ambiente e à produção agropecuária, o que levou o Ministério do Meio Ambiente a decretar sua nocividade e a autorizar sua captura e abate em todo território nacional, por tempo indeterminado. Na região onde a etnografia se concentrou, conhecida como Campanha gaúcha, os suínos asselvajados têm protagonizado ataques ao rebanho ovino, o que os alçou à condição de inimigos da pecuária local. Partindo deste conflito e das negociações estabelecidas entre agentes públicos, proprietários rurais e controladores voluntários, a tese rastreia as controvérsias hoje vigentes no país a respeito do Sus scrofa, bem como as escolhas técnicas efetuadas na região tendo em vista seu controle e manejo. Da mesma maneira, examina os impactos da presença do javali na Campanha gaúcha a partir das relações e analogias estabelecidas pelos agentes locais entre este e outros problemas que afetam o seu cotidiano, como: demais processos de invasão biológica que afetam o bioma Pampa, o declínio socioeconômico da pecuária sulina e o abigeato fronteiriço. Por fim, a tese também analisa os novos contextos de biossegurança produzidos no Brasil a partir da legalização do abate do animal, sob o prisma do conceito antropológico de sacrifício. No plano teórico, a tese se guia pelo conceito de feralidade, nela empregado para refletir sobre a resistência da espécie às tentativas humanas de domesticá-la. / This thesis examines the social reactions to the biological invasion process of European wild boar (Sus scrofa) and their breed with domestic pigs, known as "javaporcos", in southern Brazil from an anthropological perspective. Currently, this species is among the top one hundred worst invasive species in the world, according to the panel on biological invasions of the International Union for Conservation of Nature (IUCN). Present in Brazil since the late 1980s, the boar has caused countless damage to the environment and agricultural production, which led the Ministry of Environment to declare it a harmful animal and to allow its capture and slaughter throughout the country, indefinitely. In the region where the ethnography was focused, known as Campanha gaúcha, feral swine have attacked the sheep, which made them enemies of the local ranching community. From this conflict and the negotiations between government officials, landowners and volunteer controllers, the thesis traces the current controversy in the country regarding Sus scrofa, as well as the technical choices made in the region to control and manage it. Similarly, the thesis examines the impact of the presence of boars in the Campanha gaúcha region, based on the relationships and analogies established by local agents between this and other issues that affect their daily lives, such as other biological invasion process that affect the Pampa biome, the socio-economic decline of the southern livestock raising industry and livestock raiding at the borders. Finally, the thesis also analyzes new biosecurity contexts created in Brazil after the slaughter of the animal was authorized, from the perspective of the anthropological concept of sacrifice. Theoretically, the thesis is guided by the concept of ferality, thus used to reflect upon the resistance of the species to human attempts to domesticate it.

A introdução de espécies cresceu nos últimos séculos e muitas delas têm se tornado problema devido à alta capacidade de invasão, modificando ecossistemas naturais e ameaçando espécies nativas. O javali (Sus scrofa) tem demonstrado grande capacidade de invasão e de produção de danos à biodiversidade e agropecuária. No Brasil, a combinação de ambientes com grãos cultivados e remanescentes de vegetação silvestre parece oferecer aos javalis condições alimentares adequadas. Neste trabalho analisamos o conteúdo estomacal de javalis abatidos por controladores para caracterizar a composição de alimentos explorados em três ecorregiões brasileiras – os Campos Sulinos, as Florestas de Araucária e o Pantanal - e avaliar os possíveis riscos que a espécie pode representar para a produção agropecuária e a conservação da biodiversidade. Examinamos a existência de padrões de dieta em cada ecorregião e sua relação com atributos dos indivíduos, do ambiente e da caça através de métodos de ordenação. Visualizamos a distribuição de macronutrientes através da ferramenta gráfica Triângulo-Retângulo de Mistura. Partes aéreas de plantas frescas e raízes formaram a base da dieta nas três ecorregiões. Quando disponíveis, grãos cultivados nos Campos Sulinos e Florestas de Araucária e frutos e sementes silvestres no Pantanal parecem ser preferidos à forragem, o que pode ser explicado por possuírem alto valor energético. Raízes e invertebrados são importantes alimentos no Pantanal, principalmente no período de vazante. Além do registro do consumo de fauna nativa houve o consumo de ovinos. Nas três ecorregiões estudadas há grande variação na proporção em que itens são encontrados em cada estômago. Estes achados sugerem que as necessidades nutricionais são menos importantes ou de difícil ajuste nas condições limitantes dos ambientes silvestres. Nos Campos Sulinos o consumo de proteínas alcançou níveis ideais para crescimento e lactação quando comparado ao porco doméstico o que sugere melhores condições de expansão e abundância nessa região. De forma geral, a dieta de javalis nas ecorregiões estudadas sugere que os principais danos à biodiversidade estejam mais relacionados com a competição difusa por exploração de recursos e alterações nos hábitats e processos ecossistêmicos pela busca por recursos do que pela predação de espécies de interesse especial de conservação. / Introduction of species has grown in recent centuries and many have become a problem due to high invasiveness, modifying natural ecosystems and threatening native species. Wild boar (Sus scrofa) has demonstrated great capacity for invasion and production of damages to biodiversity and agriculture. In Brazil, the combination of environments with cultivated grains and remnants of wild vegetation seems to offer the wild boars adequate food conditions. In this study, we analyzed the stomach contents of wild boars slaughtered by controllers to characterize the composition of foods exploited in three Brazilian ecoregions characterized by mosaics of fields and forests – the South Brazilian Campos, the Araucaria Forests and Pantanal - and to evaluate the possible risks that the species can represent for agricultural production and conservation of biodiversity. We examined the existence of dietary patterns in each ecoregion and its relation with individuals' attributes, the environment and hunting through ordering methods. We visualize the macronutrient distribution through the right-angle misture triangle (RMT) tool. Aerial parts of fresh plants and roots formed the basis of diet in the three ecoregions. When available, grains grown in the South Brazilian Campos and Araucaria Forests and wild fruits and seeds in the Pantanal seem to be preferred to the forage, which can be explained by their high energy value. Roots and invertebrates are important food in the Pantanal, especially in the period of ebb. In addition to the consumption of native fauna, there was consumption of sheep. In the three ecoregions studied there is great variation in the proportion in which items are found in each stomach. These findings suggest that nutritional needs are less important or difficult to adjust under conditions that limit wild environments. In the Shouth Brazilian Campos the protein consumption reached optimal levels for growth and lactation when compared to the domestic pig, which suggests better conditions of expansion and abundance in this region. In general, the wild boar diet in the ecoregions studied suggests that the main damages to biodiversity are more related to the diffuse competition for resource exploitation and changes in habitats and ecosystem processes due to the search for resources than for the predation of species of special interest to conservation.

However, cryopreservation damages spermatozoa, decreasing their fertilizing potential when frozen semen is deposited in the cervix. Sperm damages attributed to cryopreservation may be minimized by the addition of seminal plasma (SP), which contains several factors produced by the testis, epididhymis and accessory glands with potential to prevent premature capacitation. Supplementation of SP prior to freezing would be beneficial for various processes of periods of the selection and freezing process, reported before freezing would be beneficial for the processes of selection and freezing. The supplementation of extenders with SP from ram and boars is associated with increased sperm motility after incubation in vitro, as well as when used for cooling, freezing and thawing. The objectives of this study were to test the addition of 20% boar SP to the extender to freeze ram sperm and to evaluate parameters of sperm quality after thawing. Ejaculates from four rams and three boars were collected to form pooled SP samples. A fraction of each pooled sample was used for protein quantification. Six samples from four rams were collected and diluted in Tris-egg yolk - glycerol for freezing, forming three treatments: control (no SP); inclusion of 20% ram SP; and inclusion of 20% boar SP. After thawing, the samples were subjected to a thermal stress test for five hours. Sperm quality was assessed every two hours. Analyses by flow cytometry were done to evaluate the integrity of acrosome and membrane integrity. For the control, ram SP and boar SP treatments, the evaluated parameters of sperm quality were: motility (30.4 ± 2.0, 24.6 ± 2.0 and 30.0 ± 2.0, respectively); membrane integrity (37.5 ± 2.6; 40.9 ± 2.6 and 31.4 ± 2.6 respectively); mitochondrial functionality (70.0 ± 1.7; 61.8 ± 1.7 and 63.6 ± 1.7); and DNA integrity (91.2 ± 3.1; 96 5 ± 3.1 and 93.6 ± 3.1 respectively). For those parameters, no significant differences were observed across treataments (P > 0.05). However, addition of boar SP to the extenders was related to greater acrosome integrity (59, 3 ± 3.5) than that of the control (46.7 ± 3.5) (P < 0.05), although both means were similar (P > 0.05) to that observed for the treatment with ram SP (56.7 ± 3.5). Despite of the benefit on acrosome integrity related to addition of boar SP, no other positive effects were observed for post-thawing ram sperm viability. / O interesse pelo uso da inseminação artificial (IA) em ovinos vem crescendo, em função do avanço no melhoramento genético. Entretanto, a criopreservação causa danos aos espermatozóides, diminuindo seu potencial fertilizante, quando a IA é feita com sêmen congelado, pela via cervical. Uma alternativa para proteger ou recuperar a célula dos danos da criopreservação é a adição de plasma seminal (PS), que contém vários fatores produzidos pelos testículos, epidídimos e glândulas acessórias do macho, com potencial de prevenir a capacitação prematura e danos gerados pelo congelamento. A adição de PS antes do congelamento seria benéfica para os processos de seleção e congelamento. A suplementação do diluente com PS ovino e suíno foi associada com aumento na motilidade espermática, após a segunda hora de incubação sob condições in vitro, assim como quando usado na refrigeração, congelamento e descongelamento. Este estudo teve como objetivo testar a adição de PS suíno (20%) ao diluente para congelamento do sêmen ovino e avaliar os parâmetros seminais in vitro pós-descongelamento. Ejaculados de quatro machos ovinos e três machos suínos foram coletados para formação de amostras combinando PS de vários machos (pools). Uma fração das amostras de PS foi destinada a quantificação de proteínas. Seis coletas dos quatro machos ovinos foram colhidas e diluídas em Tris-gema de ovo-glicerol, para congelamento, compondo três tratamentos: controle (sem PS); inclusão de 20% de PS ovino; e inclusão de 20% PS suíno. Após o descongelamento, as amostras foram submetidas a um teste de termo resistência durante cinco horas. Avaliações de qualidade espermática foram realizadas a cada duas horas. Também foram realizadas análises por citometria de fluxo para as avaliações de integridade de acrossoma e integridade de membrana. Para os tratamentos controle, PS ovino e PS suíno, não foram observadas diferenças (P > 0.05) quanto a motilidade (30,0 ± 2,0; 30,4 ± 2,0 e 24,6 ± 2,0 respectivamente), integridade de membrana (37,5 ± 2,6; 40,9 ± 2,6 e 31,4 ± 2,6, respectivamente), função mitocondrial (70,0 ± 1,7; 61,8 ± 1,7 e 63,6 ± 1,7, respectivamente) e integridade de DNA (91,2 ± 3,1; 96,5 ± 3,1 e 93,6 ± 3,1, respectivamente). A integridade do acrossoma foi maior (P < 0.05) com inclusão de PS suíno (59,3 ± 3,5) em comparação com o controle (46,7 ± 3,5), mas ambas as médias foram similares (P > 0.05) à observada para o PS ovino (56,7 ± 3,5). Conclui-se que apesar do beneficio do PS suíno a 20% para a integridade de acrossoma, não se obteve resultados positivos nas demais avaliações de qualidade seminal.

Studies in zoo-archaeological Neolithic contexts is the study of early animal domestication in relation to humans transitioning into a more sedentary species. Research and documentation are vital for reconstructing the mechanisms behind the threshold event. In this thesis, teeth of Suidae have been documented, analysed and compared osteologically and interpreted cross-culturally. In addition, aDNA, isotope, coat colour and physical mammal size affecting factor studies are presented to contextualise this thesis. Primary osteological methods are Mandibular Wear Stage (MWS), Linear Enamel Hypoplasia (LEH) recordings and lower jaw third molar (M3) length measurement. These methods can detect biometric domestication markers. The analysed Suidae teeth are from the Middle Neolithic site of Ajvide, Gotland, Sweden. A collection of modern wild boar act as Control sample. These teeth are compared primarily with known domestic pig teeth sample statistics from the British Late Neolithic site of Durrington Walls, Wiltshire, United Kingdom. Results indicate that the Middle Neolithic Pitted Ware culture (PWC) on Gotland hunted during winter and kept limited numbers of captive wild boars as totemic animals (pets) possibly bound to land and ancestry. However, an exact reconstruction of the PWC pig pet keeping practices are uncertain due to human-pig relationships being highly dynamic. Intensified pig hunting, not pet keeping should be considered early domestication. Domestication carries with it detectable biometric markers, which seem to be rare in the Neolithic. The cross-cultural comparisons on traditional pig ‘low-intensity husbandry’ can attest to a human-pig relationship of hunter-gatherers keeping captive wild animals. The pig was not a staple food for the PWC and thus not intensively hunted, rather pigs were rare ritualistic commodities and likely highly praised. Perpetuating this human-pig relationship could have been maintained by PWC ‘big men’ that engaged in socio-political lavish giveaways at festivities and funerals, thus ‘hogging wealth’, but never domesticated the pig. / Studier i neolitiska zoo-arkeologiska sammanhang är undersökningar av tidig domesticering av djur i förhållande till mänsklighetens övergång till en mer stillasittande art. Forskning och dokumentation är avgörande för att rekonstruera mekanismerna bakom övergången. I denna uppsats har svintänder dokumenterats, analyserats och jämförts osteologiskt och tolkats tvärkulturellt. Studier i aDNA, isotop, pälsfärg och fysiska storleksfaktorer hos däggdjur presenteras också för att kontextualisera denna uppsats. Primära osteologiska metoder är tandslitage i underkäke (MWS), linjär emaljhypoplasi (LEH) och underkäkens tredje molar (M3) mätningar. Dessa metoder kan finna biometriska domesticeringsmarkörer. De analyserade svintänderna kommer ifrån den mellanneolitiska lokalen Ajvide, Eksta socken, Gotland. En samling moderna vildsvin agerar kontrollmaterial. Dessa tänder jämförs i första hand med kända domesticerade stenåldersvin från den Brittiska senneolitiska lokalen Durrington Walls, Wiltshire, Storbritannien. Resultaten indikerar på att den mellanneolitiska gropkeramiska kulturen (GRK), jagade på Gotland under vinterhalvåret och tog tillfånga ett begränsat antal svin som husdjur (totemdjur). Troligen togs svin tillfånga av olika ’hus’ till följd av att svinet var bundet till land och förfäder. En exakt rekonstruktion av GRKs svinhållningspraktik är dock osäkert på grund av att människo-svin relationer är dynamiska. Intensifierad svinjakt, inte tillfångatagandet av enstaka djur bör betraktas som tidig domesticering. Domesticering medför speciella biometriska markörer som är ovanligare i neolitisk tid. De tvärkulturella jämförelserna i traditionell "lågintensiv svinhållning" kan intyga på ett sådant förhållande mellan jägare-samlar grupper och vildsvin. Även om svinet inte var en basföda åt GRK, och därmed inte intensivt jagade, var svinen sällsynta ritualistiska handelsvaror och troligen högt värdesatta. Gropkeramiska "stormän" kan ha varit de drivande bakom denna praktik. Dessa ”stormän” engagerade sig i sociopolitiska aktiviteter, festligheter och begravningar, och därmed hade "hamstrat välstånd", men domesticerade aldrig svinet.

Various animal or vegetable origin bio-indicators are used for the assessment of the environmental contamination. The wild animals were chosen for monitoring of xenobiotic based organohalogen compounds. The district health facility staff collected the samples of wild boars in the territory of Central Bohemia. The controlled substances were isolated from the matrix by an extraction. The extraction was made by a petrolether and then it was purified by a column chromatography. A final cleansing of the extract was made by an acid hydrolysis. The determination of the selected analytes was finished by the method of gas chromatography with an electron capture detector. The results gave us basic information about the wild boar contamination of organohalogen pollutants.

Background: In recent years, several new ELISAs for the detection of antibodies against the porcine reproductive and respiratory disease virus (PRRSV) in pig serum have been developed. To interpret the results, specificity and sensitivity data as well as agreement to a reference ELISA must be available. In this study, three commercial ELISAs (INgezim PRRS 2.0 - ELISA II, Priocheck® PRRSV Ab porcine – ELISA III and CIVTEST suis PRRS E/S PLUS - ELISA IV, detecting PRRSV type 1 antibodies) were compared to a standard ELISA (IDEXX PRRS X3 Ab Test - ELISA I). The serum of three pigs vaccinated with an attenuated PRRSV live vaccine (genotype 2) was tested prior to and several times after the vaccination. Furthermore, serum samples of 245 pigs of PRRSV positive herds, 309 pigs of monitored PRRSV negative herds, 256 fatteners of assumed PRRSV negative herds with unknown herd history and 92 wild boars were tested with all four ELISAs. Results: ELISAs II and III were able to detect seroconversion of vaccinated pigs with a similar reliability. According to kappa coefficient, the results showed an almost perfect agreement between ELISA I as reference and ELISA II and III (kappa > 0.8), and substantial agreement between ELISA I and ELISA IV (kappa = 0.71). Sensitivity of ELISA II, III and IV was 96.0%, 100% and 91.5%, respectively. The specificity of the ELISAs determined in samples of monitored PRRSV negative herds was 99.0%, 95.1% and 96.4%, respectively. In assumed negative farms that were not continually monitored, more positive samples were found with ELISA II to IV. The reference ELISA I had a specificity of 100% in this study. Conclusions: All tested ELISAs were able to detect a PRRSV positive herd. The specificity and sensitivity of the tested commercial ELISAs, however, differed. ELISA II had the highest specificity an ELISA III had the highest sensitivity in comparison to the reference ELISA. ELISA IV had a lower sensitivity and specificity than the other ELISAs.

Naturbetesmarker är ett av de artrikaste markslagen vi har, för att hålla dem öppna med betande djur finns ett miljöstöd från landsbygdsprogrammet utformat för att gynna den biologiska mångfalden. Vildsvinen (Sus Scrofa) har under de senaste årtiondena ökat markant, vilket har lett till stora ekonomiska konsekvenser för lantbruket genom skador på jordbruksmark. Av tidigare forskning kan vi se att skadorna inte påverkar den biologiska mångfalden negativt. Biologisk mångfald är en central del i det miljöstöd som lantbrukarna får för att hålla sina naturbetesmarker öppna. Men vad säger markägarna om vildsvinsproblematiken på naturbetesmark och hur ser de på framtiden? Studien utgår från markägarnas perspektiv, där vi undersöker hur markägarna upplever vildsvinsskador på deras naturbetesmarker och hur skadorna påverkar deras skötsel. Vi undersöker även hur markägarna upplever den rådgivning och stöd som de får från berörd myndighet samt vilka förändringar de vill se i vildsvinsförvaltningen. Vi valde i studien att använda oss av kvalitativa forskningsintervjuer, där sex markägare intervjuades. Resultatet i studien visar att markägarna upplever att det största problemet är att skadorna är tidskrävande och kostsamma att rätta till. Det framkom även kritik mot dagens utformning av miljöstödet och att trycket från vildsvinsstammen måste minska för att man ska orka att hålla sina marker öppna i framtiden. Slutsatsen är att det måste till ett större helhetsgrepp kring vildsvinsförvaltningen för att minska skadorna och mer individuell rådgivning för den enskilda markägaren. / Pasturelands is a land with high biodiversity, in order to keep them open with herbivores, there is environmental support from Landsbygdsprogrammet designed to benefit the biological diversity. Wild boars (Sus Scrofa) have increased markedly in recent decades, which has led to major economic consequences for agriculture and it´s land. From previous research, we can see that the damage does not adversely affect biodiversity. Biodiversity is a central part of the environmental support that the farmers receive to keep their pasturelands open. But what does landowners say about the problems with wild boar on pasturelands and how do they look on the future? The study is based on the landowners ‘perspective, we examine how landowners experience wild boar damage to their pasturelands and how the damage affects their management. We also examine how landowners experience the advice and support they receive from the authority and what changes they want to see in wild boar management. In the study, we choose to use qualitative research interviews, in which six landowners were interviewed. The result of the study show that landowners feel that the biggest problem is that the damage is time-consuming and costly to repair. There was also criticism of today´s design of environmental support and the pressure from the wild boar population must be reduced in order to keep their land open in the future. The conclusion is that there must be a greater holistic approach to wild management to reduce the damage and more individual advice for the individual landowner.

The study was focused on disturbances by wild boar (Sus scrofa) and their impact on vegetation of semi-dry grasslands (Festuco-Brometea) dominated by Brachypodium pinnatum. The research was conducted in military area Hradiště in hilly region of the Doupovské hory. Wild boar rooting activities is main source of disturbances regime in this abandoned, previously agricultural area. The vegetation of artificial small scale soil disturbances was compared to undisturbed control plots and vegetation of natural disturbances by wild boar. Experimental plots were established during the summer 2007. Consequently a vegetation survey of these plots was carried out and soil was mechanically disturbed. Succession on disturbances was annually monitored. The surrounding natural disturbances were also mapped three times a year as a potential source of diaspores and to assess their frequency and effect on the landscape level. The list of species in the 2m, 4m and 16m distance from the experimental plot was also made. Results: Disturbances by wild boar increased species diversity and spatial heterogeneity of semi-dry grasslands. There were some species found on experimental plot, which were present not in the surrounding matrix. Most of them belong to hemicryptophytes and species with long-term persistent diaspores. Presence of...

The wild boar is known to disturb the forest floor by rooting in the soil as they search for food. Soil is a vital part of the carbon cycle and stores large amounts of carbon. There is limited knowledge on how this feeding behavior may alter the content of organic matter in the soil and consequently the ability of the soil to store carbon. The objective of this study was to examine the effects of rooting on organic matter concentration by (1) comparing soil from rooted and un-rooted plots and (2) investigating whether the density of rooted areas within each plot affects organic matter concentration. Our results showed no effects of rooting on organic matter concentration. The soil in our study area contained very high concentrations of organic matter (83%) which could have been a factor in why no effects were detected. Our overall results indicate that rooting does not, in the short term, affect the ability of the soil to store carbon in a coniferous forest in southern Sweden. However, this does not exclude rooting as a potential factor influencing soil carbon storage, as several other studies have detected significant differences in soil concentration. The complexity of ecosystems and factors influencing their properties leads to contrasting results between studies. It is relevant in a climate change perspective to further investigate the effects rooting may have on carbon storage in the soil.

Studien är ett designdrivet forskningsprojekt som besvarar frågeställningen: Vilka materiella designkvalitéer finns det i svenskt vildsvinsläder och hur kan dessa appliceras i produktdesign? Frågeställningen undersöks främst genom en material driven designmetod och resultatet analyseras genom teorier om design för hållbar utveckling och design för emotionell varaktighet. Den material drivna designmetoden inleddes med fri utforskning av materialet, första intryck dokumenterades och hypoteser kring materialet dömdes inkorrekta. För att undersöka de tekniska egenskaperna utfördes materialtester. Materialupplevelsen utforskades genom ett metodverktyg där 10 deltagare besvarade frågor kring materialets performativa, sensoriska, affektiva och tolkande egenskaper. Testerna avslutades med en reflektion av materialets positiva, negativa och unika egenskaper. Kunskapen av vildsvinslädrets designkvalitéer används sedan i en idégenerering process för att skapa en hållbar produkt med emotionell varaktighet. Idégenerering mynnar ut i studiens designförslag, en stol med dyna och ryggstöd av vildsvinsläder. Studien avslutas med en slutsats som bekräftar designkvalitéerna i vildsvinläder och en diskussion som belyser insikter som uppkommit under studiens genomförande. / The study is a design-driven research project that answers the question: What material design qualities are there in Swedish wild boar leather and how can these be applied in product design? The question is primarily investigated through a material-driven design method and results is analysed through theories of design for sustainable development and design for emotional durability. The material-driven design method began with free exploration of the material, first impressions were documented and hypotheses about the material were deemed incorrect. To investigate the technical characteristics, tests were carried out. The material experience is explored through a tool where 10 participants answered questions about the material's performative, sensory, affective, and interpretive properties. The tests ended with a reflection of the material's positive, negative, and unique properties. The knowledge of the design qualities of wild boar leather was then used in an idea generation process to create a sustainable product with emotional durability. The idea generation culminates in the study's design proposal, a chair with cushion and backrest made of wild boar leather. The study concludes with a conclusion that confirms the design qualities of wild boar leather and a discussion that highlights insights that emerged during the study's implementation.
