Official protection of an exploited species sometimes precedes any quantitative understanding of its use, including any dependence of local residents on it for food and livelihood. Conservation initiatives could suffer without this information. The Goliath frog Conraua goliath is iconic globally because of its large size, and is categorized as Endangered on the IUCN Red List. The main threat to this species in Cameroon is overexploitation, but any associated socio-economic aspects of this have not been quantified. We provide insights into local perceptions of the Goliath frog and its consumption through structured interviews with 223 people living alongside this species. The Goliath frog is well known and hunted both for home consumption and the wild meat trade. We trailed seven collaborative Cameroonian Goliath frog hunters over two seasons to determine offtake. A total of 192 Goliath frogs were collected by these hunters, peaking in March. The hunters used nets, shotguns and spears. Their catch was eaten at home or sold fresh within the community or to travellers for XAF 1,500–5,000 (USD 3–10) each. We also studied the Goliath frog trade by examining the databases of the Cameroonian Ministry of Forestry and Wildlife, and CITES. CITES and hunters reported large exports of Goliath frogs but no trade was documented by the Ministry of Forestry and Wildlife. To support conservation planning, this study provides preliminary quantitative information on the extent of the threat of hunting to this Endangered frog.

As the largest felid in the Americas, the jaguar Panthera onca has both ecological and cultural significance in Bolivia. Yet jaguar populations are declining because of multiple pervasive anthropogenic pressures, including domestic and international demand for their body parts. Since 2013, Bolivia has become a centre of the illegal trade of jaguar body parts, driven by demand from Chinese markets. From 2021, there have been anecdotal reports of jaguar body parts being sold to prisons in north-western Bolivia, where inmates use them to make crafts to be sold at local markets. Here we provide further insights into this illegal wildlife trade activity. Specifically, we show that inmates at Mocovi prison in Trinidad purchase skins of jaguars and other wild animals directly from hunters and from vendors at local markets. Goods (wallets, hats and purses) produced from the skins are sold back to vendors by the inmates to provide income for their daily sustenance. Testimony from an inmate also stated that large bulk orders for wildlife products had been received from a non-Bolivian client base. The San Borja municipality in Beni was indicated as a key location where jaguars are being targeted for their skins to supply the illegal production of wildlife products in Mocovi prison. Further studies are required to determine the extent of this illegal activity in Mocovi prison and other prisons in Bolivia, and in other Latin American countries.

Although wildlife trade has received considerable research and conservation attention, much of it has been focused on charismatic species, with taxa such as fungi receiving little or no attention despite being highly sought after. The caterpillar fungus Ophiocordyceps sinensis is highly valued as an ingredient in cosmetics and medicines, and as an aphrodisiac and dietary supplement. Despite its livelihood and socio-economic significance, it has received little attention in either research or wildlife trade policy. Nevertheless, trade appears to be rampant, and growing online, and this is an emerging conservation challenge. Here we present a systematic survey of online trade in the caterpillar fungus during 2021. During this period, 168 advertisements were recorded on eight e-commerce platforms, both national and international. The grade of the caterpillar fungus advertised for sale fell into six categories. Fungi described as pure/organic/wild grade, which we categorized as authentic grade, had the highest median price (24 USD/g) and those described as medicine/food/cosmetic/beverage, which we categorized as consumption grade, had the lowest median price (0.04 USD/g). The highest advertised sale price was for caterpillar fungus of Bhutan origin (155 USD/g) advertised on the eBay e-commerce platform. Trade in caterpillar fungus on national and international online platforms is evident, and trade in other non-charismatic species is also likely burgeoning online but remains poorly documented. Further systematic surveys of online trade are required, not only to improve understanding of such trade but also to facilitate the development of effective conservation interventions and prevent undocumented overexploitation of important natural resources in developing countries.

Commercial use of wildlife is booming. However, knowledge of trade, price structure and benefit distribution mechanisms remain limited for many endemic, threatened and economically valuable species, impeding efforts to develop conservation intervention schemes in line with sustainable objectives. We illustrate the nature of commercialization of the caterpillar fungus Ophiocordyceps sinensis, collected in a high-altitude Tibetan region. Using the value-chain approach, we document how caterpillar fungus is collected in a remote mountainous region and traded across a wide range of middlemen until it finally reaches high-end markets in urban centres. Mapping the caterpillar fungus value chain helps identify the actors involved and the social institutions (i.e. the rules, norms and arrangements that shape people's behaviours) facilitating access to markets and influencing profit distribution and price structure. We present the complex dynamics of this commercialization process, providing a holistic value-chain analysis that encompasses actors, profits and institutions.
