Abstract

The global pet trade in invertebrates remains poorly understood and underrepresented in policy and research. Tarantulas are a highly traded invertebrate group. Many individuals in trade are wild caught, and trade regulation is often lacking, raising concerns about the effect of trade on local ecosystems and populations. We addressed local concerns surrounding the international trade of Tapinauchenius rasti (Caribbean diamond tarantula), which is endemic to Saint Vincent and the Grenadines. We assessed the extinction risks associated with this widely traded species by analyzing supply of and demand for the species with the COM-B (capability, opportunity, motivation, behavior) model. This model breaks down decision-making into capability, opportunity, and motivation. We interviewed stakeholders throughout the supply chain and analyzed content of an online hobbyist forum and a time series of prices for this species and other tarantulas. In terms of motivation, there was limited preference for the Caribbean diamond tarantula due to its morphology and behavior. In terms of opportunity, the species was readily available, primarily through captive breeding. Collecting wild specimens is challenging due to enforcement measures and logistical difficulties, making it an unprofitable endeavor. In terms of capability, the species was relatively low in price, likely because it is easy to breed in captivity. As a result, the current wildlife trade does not pose a significant threat to the Caribbean diamond tarantula. Our methodology can serve as a valuable tool for assessing potential threats posed by trade to other spider species and possibly other invertebrates. Understanding these threats is crucial for promoting responsible and sustainable trade practices that minimize risks to wild populations while ensuring equitable benefits for communities coexisting with wildlife.

评估宠物贸易中狼蛛物种的过度开发风险。
人们对无脊椎动物的全球宠物贸易仍然知之甚少,在政策和研究中的代表性也不足。毛蛛是一种交易量很大的无脊椎动物。贸易中的许多个体都是野生捕获的,贸易监管往往缺失,这引发了人们对贸易对当地生态系统和种群影响的担忧。我们探讨了当地对圣文森特和格林纳丁斯特有的加勒比钻石蛛(Tapinauchenius rasti)国际贸易的担忧。我们利用 COM-B(能力、机会、动机、行为)模型分析了该物种的供需情况,从而评估了与这一广泛贸易物种相关的灭绝风险。该模型将决策分解为能力、机会和动机。我们采访了整个供应链中的利益相关者,分析了网上爱好者论坛的内容以及该物种和其他狼蛛的价格时间序列。在动机方面,由于加勒比钻石狼蛛的形态和行为,人们对它的偏好有限。就机会而言,该物种很容易获得,主要是通过人工繁殖。由于执法措施和后勤方面的困难,采集野生标本具有挑战性,因此无利可图。就能力而言,该物种的价格相对较低,这可能是因为它易于人工繁殖。因此,目前的野生动物贸易不会对加勒比钻石蛛构成重大威胁。我们的方法可以作为一种宝贵的工具,用于评估贸易对其他蜘蛛物种以及可能对其他无脊椎动物造成的潜在威胁。了解这些威胁对于促进负责任和可持续的贸易行为至关重要,这种贸易行为可以最大限度地降低对野生种群的风险,同时确保与野生动物共存的社区获得公平的利益。

期刊介绍: Conservation Biology welcomes submissions that address the science and practice of conserving Earth's biological diversity. We encourage submissions that emphasize issues germane to any of Earth''s ecosystems or geographic regions and that apply diverse approaches to analyses and problem solving. Nevertheless, manuscripts with relevance to conservation that transcend the particular ecosystem, species, or situation described will be prioritized for publication.
