- Abstract
Wildlife trade is among the main threats to biodiversity conservation and may pose a risk to human health because of the spread of zoonotic diseases. To avoid social, economic and environmental consequences of illegal trade, it is crucial to understand the factors influencing the wildlife market and the effectiveness of policies already in place. I aim to unveil the biological and socioeconomic factors driving wildlife trade, the health risks imposed by the activity, and the effectiveness of certified captive-breeding as a strategy to curb the illegal market in Latin America through a multidisciplinary approach. I assess socioeconomic correlates of the emerging international trade in wild cat species from Latin America using a dataset of >1,000 seized cats, showing that high levels of corruption and Chinese private investment and low income per capita were related to higher numbers of jaguar seizures. I assess the effectiveness of primate captive-breeding programmes as an intervention to curb wildlife trafficking. Illegal sources held >70% of the primate market share. Legal primates are more expensive, and the production is not sufficiently high to fulfil the demand. I assess the scale of the illegal trade and ownership of venomous snakes in Brazil. Venomous snake taxa responsible for higher numbers of snakebites were those most often kept as pets. I uncover how online wildlife pet traders and consumers responded to campaigns associating the origin of the COVID-19 pandemic. Of 20,000 posts on Facebook groups, only 0.44% mentioned COVID-19 and several stimulated the trade in wild species during lockdown. Despite the existence of international and national wildlife trade regulations, I conclude that illegal wildlife trade is still an issue that needs further addressing in Latin America. I identify knowledge gaps and candidate interventions to amend the current loopholes to reduce wildlife trafficking. My aspiration with this thesis is to provide useful information that can inform better strategies to tackle illegal wildlife trade in Latin America.

- Abstract
It is challenging to disentangle the legal and illegal aspects of wild-caught animals that are traded in wildlife markets or online, and this may diminish the value of conducting wildlife trade surveys. We present empirical studies on the trade in birds (ducks, owls, songbirds, non-passerines) in Indonesia (2005 to 2021). Based on visits to wildlife markets, wholesale traders, and monitoring of an Instagram account, we examine if five specific pieces of legislation (domestic and international) are adhered to: (1) protected species, (2) harvest quota, (3) welfare, (4) provincial transport restrictions, and (5) illegal import of CITES-listed species. Our five distinctly different case studies showed that in each case, certain rules and regulations were adhered to, whilst others were violated to varying degrees. When trade involved non-protected species, there was frequently a lack of harvest quotas or trade occurred above these allocated quotas. Basic welfare provisions were regularly and habitually violated. Visiting wildlife markets and recording first-hand what is openly offered for sale is a highly reliable, verifiable, and valuable method of data collection that can give insight in numerous aspects of the animal trade. Our research provides support for recognising the urgency for the government to take appropriate action to curb all the illegal aspects of the bird trade in Indonesia.

The aim of this study was to test the use of measures obtained from freelisting as possible surrogates of the harvest rate of hunted species. For this purpose, we interviewed 100 rural and urban hunters in southwestern Amazonia to obtain the frequency of citations of each hunted species through freelisting and gather information on the number of individuals hunted per species in the last five hunting events through hunting recalls. We assessed the relationship between the percentage of records per species by each method through a generalized linear model, and then compared the predicted values obtained from this model with the values observed in our dataset using Pearson's correlation. During freelisting, fortythree taxa were listed in 608 citations as hunted by the informants. Freelisting provided data on around twice the number of species obtained from recalls. During the last five hunting trips, urban hunters reported the hunting of 164 individuals of 18 species, representing 54.5% of the freelisted species. Rural hunters caught 146 individuals of 21 species, 60.0% of the freelisted species. We found a strong logistic relationship between the harvest rates, i.e., percentage of individuals hunted per species from recalls, and the freelisting percentage citations of hunted species, with the estimated and observed values of harvest rates highly matching (Pearson's R = 0.98, p < 0.0001). The freelisting method allowed a good estimate of the composition and harvest rates of hunted species. The formula produced in this study can be used as a reference for further studies, enabling researchers to use freelisting effectively to assess the composition of hunted species and to address the difficulty of obtaining reliable data on species harvest rates in tropical forests, especially in short-term studies and contexts in which hunters distrust research.

Os quelônios de água doce foram intensamente explorados ao longo de séculos e atualmente figuram entre os grupos de vertebrados mais ameaçados do mundo. Neste estudo, nós discutimos a sustentabilidade do uso de quatro espécies de quelônios de água doce por meio da avaliação de flutuações na produtividade da caça, biomassa corporal de indivíduos caçados e preços de venda em mercados rurais e urbanos ao longo dos anos. Para tanto, nós apresentamos os padrões de exploração de quelônios e aplicamos modelos de aditivos generalizados (GAMLSS) utilizando um monitoramento participativo da caça de quelônios de água doce por 14 anos em 10 comunidades dentro de duas reservas habitadas na Amazônia Central. Nós registramos 2.767 indivíduos de tartarugas de água doce caçados, totalizando 10.186,30 kg de biomassa abatida. Podocnemis sextuberculata foi a espécie mais caçada em número de indivíduos (n = 1538, 55,6%), enquanto que Podocnemis unifilis representou a maior parte da biomassa abatida (n = 4360,6, 63,7%). O comércio de quelônios de água doce movimentou, ao menos, US$ 31.606,60, e enquanto P. unifilis e Podocnemis expansa foram relevantes para o mercado urbano, Peltocephalus dumerilianus e Podocnemis sextuberculata desempenharam um papel crucial na garantia da soberania alimentar para a população rural. Os preços de venda de P. unifilis aumentaram ao longo dos anos de monitoramento, sendo que sua carne alcançou maiores valores nos centros urbanos. Após cerca de 20 anos de proteção e manejo participativo de quelônios nas reservas, detectamos fortes evidências de um início de recuperação populacional dos quelônios na região, uma vez que a captura-por-unidade-de- esforço das fêmeas de P. sextuberculata e P. unifilis aumentou ao longo dos anos. Além disso, a massa corporal de ambos os sexos de P. expansa e P. dumerilianus aumentou fortemente ao longo do período de monitoramento. Nossos resultados destacam a eficácia das áreas protegidas habitadas na conservação de espécies alvos de caça, bem como a relevância do monitoramento comunitário como estratégia para conservar espécies longevas, como os quelônios amazônicos. A recuperação das populações de quelônios é importante não somente para manter a biodiversidade e os serviços ecossistêmicos na Amazônia, mas também por proporcionar benefícios sociais, econômicos e de saúde para os moradores locais. Freshwater turtles have been intensively harvested for centuries and currently figure as one of the most threatened vertebrate groups in the world. Using data from 14-years of participatory monitoring of hunting in 10 communities within sustainable development reserves, we reveal patterns and trends of chelonian exploitation in Central Amazonia. We applied generalized additive models to assess use sustainability of four endangered Amazonian freshwater turtles via fluctuations in hunting productivity, body mass of hunted individuals, and selling prices in rural and urban markets over the study-period. We recorded 2,767 hunted individual freshwater turtles (summed biomass, 10,186.30 kg). Six-tubercled Amazon river turtle (Podocnemis sextuberculata) was the most hunted species by number of individuals (n=1538, 55.6%), while yellow-spotted river turtles (Podocnemis unifilis) accounted for most of the hunted biomass (n= 4360.6, 63.7%). Trade in turtles generated an overall profit of US$ 31,606.60, and while P. unifilis and South American giant river turtles (Podocnemis expansa) were relevant in the urban market, big-headed Amazon river turtles (Peltocephalus dumerilianus) and P. sextuberculata played a crucial role in guaranteeing food security for rural people. Selling prices increased during the monitoring period, with higher values obtained for some species in urban centres. After some 20 years under protection and participatory management, we detected strong evidence of chelonian population recovery in the region, since the catch-per-unit-effort and female body mass of P. sextuberculata and P. unifilis, and the body mass of both sexes of P. expansa and P. dumerilianus increased over the monitoring period. Our results highlight the effectiveness of inhabited protected areas in conserving game species, as well as the relevance of community-based monitoring as an efficient strategy to preserve long-lived chelonians in Amazonia. Chelonian population recovery helps maintain biodiversity and ecosystem services in Amazonia, and also provides social, economic and health benefits for local dwellers.
