Abstract: The unrivaled growth in e‐commerce of animals and plants presents an unprecedented opportunity to monitor wildlife trade to inform conservation, biosecurity, and law enforcement. Using the internet to quantify the scale of the wildlife trade (volume and frequency) is a relatively recent and rapidly developing approach that lacks an accessible framework for locating relevant websites and collecting data. We produced an accessible guide for internet‐based wildlife trade surveillance. We detailed a repeatable method involving a systematic internet search, with search engines, to locate relevant websites and content. For data collection, we highlight web‐scraping technology as an efficient way to collect data in an automated fashion at regularly timed intervals. Our guide is applicable to the multitude of trade‐based contexts because researchers can tailor search keywords for specific taxa or derived products and locations of interest. We provide information for working with the ersity of websites used in wildlife trade. For ex le, to locate relevant content on social media (e.g., posts or groups), each social media platform should be examined in idually via the site's internal search engine. A key advantage of using the internet to study wildlife trade is the relative ease of access to an increasing amount of trade‐related data. However, not all wildlife trade occurs online and it may occur on unobservable sections of the internet.

Abstract: The pet trade is a major driver of both bio ersity loss and the introduction of invasive alien species. Building a comprehensive understanding of the pet trade would improve prediction of conservation and biosecurity threats, with the aim to prevent further negative impacts. We used South Australia’s native wildlife permit reporting system as a data‐rich ex le of a vertebrate pet market, spanning 590 distinct taxa across 105 families of terrestrial vertebrates (mammals, reptiles, birds and hibians). Using a piecewise structural equation modelling (SEM) approach, we tested the influence of 11 a priori variables relating to pets (e.g. species traits), pet owners (e.g. socioeconomic metrics) and regulatory systems (e.g. permit requirements) on the quantities of captive pet keeping, breeding, trading and escapes into the wild. Birds and reptiles with higher annual fecundity were more likely to be kept in captivity and birds with larger adult mass were more likely to be sold. Species with more stringent permit requirements were possessed and escaped, in lower abundances. Pet keeping was weakly correlated with regions of lower human population densities and higher unemployment rates, yet all socioeconomic variables were ultimately poor at explaining trade dynamics. More escapes occurred in regions that possessed larger quantities of pets, further emphasising the role of propagule pressure in the risk of pet escapes. Synthesis and applications . Species traits are a strong determinant of native pet trade dynamics, yet permit systems also play a key role in de‐incentivising undesirable trade practices. While our research highlighted the positive potential of trade regulatory systems, we recommend that consistent permit category criteria are established to reduce trade in threatened species as well as invasive alien species of high biosecurity risk. Implementation of such systems is broadly needed across a greater ersity of wildlife markets and jurisdictions.

Abstract: The Philippine Sailfin Lizard (Agamidae: Hydrosaurus pustulatus) is a nationally protected Philippine endemic species. It is threatened by habitat destruction, pollution and overexploitation for the domestic pet trade, yet less is known about the international component of the trade. Here we investigate the international trade in Hydrosaurus spp. (H. weberi, H. amboinensis, and H. pustulatus) with an emphasis on H. pustulatus. We analysed international seizures combined with international online sales and trade data for the United States of America (USA). The export of H. pustulatus from the Philippines has been prohibited since 1991, except under special circumstances, yet they continue to be traded internationally, and we found evidence for trade in Asia, Europe, and North America. Most of these animals, however, were declared to be captive-bred. While imports to and exports from the US consisted mostly of other species of Hydrosaurus, H. pustulatus was by far the most coveted species online, with prices significantly higher for H. pustulatus than any of the other species. While not many seizures have occurred outside the Philippines, even wild-caught in iduals were found to be ‘legally’ imported to the USA – in apparent violation of the Lacey Act. We recommend H. pustulatus to be listed in CITES Appendix III, in order for countries other than the USA to have a legal basis to seize wild-caught animals trafficked from the Philippines and to monitor trade in captive-bred specimens. Further, we suggest the use of automated cross-referencing between imported species and the national protection status of the species’ native range states to ensure that legislation violations are detected at the point of import.

Abstract: Globalisation of the live pet trade facilitates major pathways for the transport and introduction of invasive alien species across longer distances and at higher frequencies than previously possible. Moreover, the unsustainable trade of species is a major driver for the over-exploitation of wild populations. Australia minimises the biosecurity and conservation risk of the international pet trade by implementing highly stringent regulations on the live import and keeping of alien pets beyond its international CITES obligations. However, the public desire to possess prohibited alien pets has never been quantified and represents a number of species that could be acquired illegally or legally under different future legislative conditions. As such, highly desirable species represent an ongoing conservation threat and biosecurity risk via the pet-release invasion pathway. We aimed to characterise the Australian desire for illegal alien pets and investigate potential sources of external information that can be utilised to predict future desire. Using public live import enquiry records from the Australian Commonwealth Department of Agriculture, Water and the Environment as a proxy for alien pet desire, we tested for differences in the proportion of species with threatened listings and records of invasions, after accounting for taxonomy. Additionally, we used a United States of America (U.S.) live imports dataset to infer pet demand in another Western market with less stringent regulations and determined whether species highly desired in Australia had higher U.S. trade demand than would be expected by chance. The Australian public desire for alien pets is heavily and significantly biased towards species threatened with extinction, species popular in the U.S. trade and species with a history of successful invasions. Not only does this indicate the potential impacts of pet desire on invasion risk and the conservation of threatened species, but we also highlight the potential role of the U.S. trade as an effective predictor for Australian desire. Our research emphasises the value of novel datasets in building predictive capacity for improved biosecurity awareness.

Abstract: Abstract ContextAustralia has a high ersity of endemic vertebrate fauna. Yet, transnational human activities continue to increase the rate of transportation, introduction and establishment of new alien vertebrates in Australia, to the detriment of environmental and socioeconomic services. Eradication of invasive vertebrates is often costly and without guarantee of success therefore, methods for detecting, intercepting and preventing the transport of alien species earlier in the invasion pathway provide substantial benefit. AimTo anticipate emergent threats to Australian biosecurity posed by the transport and introduction of new alien vertebrates over time. MethodsWe collated vertebrate interception data from various mainland Australian State, Territory and Commonwealth government reporting agencies, including data from a previously published study, at both pre-border and post-border stages from 1999 to 2016. Using generalised linear and generalised additive modelling, we predicted trends in interception frequency using predictors such as vertebrate taxa, detection category and alien status. Key resultsInterception frequency increased over time for all vertebrate classes, for pre-border stowaways and for post-border captive and at-large interceptions, with no saturation in the accumulation of new species over time. Five species were responsible for almost half of all incidents, of which red-eared sliders (Trachemys scripta elegans), boa constrictors (Boa constrictor) and corn snakes (Pantherophis guttatus) are prominent in Australia’s illegal alien pet trade. Rose-ringed parakeets (Psittacula krameri) are prominent in the legal alien cage-bird trade, which remains poorly regulated. Asian common toads (Duttaphrynus melanostictus) were frequently detected as stowaways, and most stowaway incidents originated from Southeast Asia, particularly Indonesia, via shipping. Data deficiency for pre-border incidents increased rapidly in 2015 and 2016. ConclusionsAustralia is subject to a persistent and increasing risk of alien vertebrate introductions and incursions over time, owing partly to emergent trends in the alien pet trade as well as increased global trade and tourism. ImplicationsThe future of Australia’s biosecurity remains dependent on stringent border security to prevent the arrival of novel species, but our findings also highlight the importance of ongoing management and control of high-risk species already present, often illegally, within Australia.

Abstract: Contemporary wildlife trade is massively facilitated by the Internet. By design, the dark web is one layer of the Internet that is difficult to monitor and continues to lack thorough investigation. Here, we accessed a comprehensive database of dark web marketplaces to search across c . 2 million dark web advertisements over 5 years using c . 7 k wildlife trade‐related search terms. We found 153 species traded in 3332 advertisements ( c . 600 advertisements per year). We characterized a highly specialized wildlife trade market, where c . 90% of dark‐web wildlife advertisements were for recreational drugs. We verified that 68 species contained chemicals with drug properties. Species advertised as drugs mostly comprised of plant species, however, fungi and animals were also traded as drugs. Most species with drug properties were psychedelics (45 species), including one genera of fungi, Psilocybe , with 19 species traded on the dark web. The native distribution of plants with drug properties were clustered in Central and South America. A smaller proportion of trade was for purported medicinal properties of wildlife, clothing, decoration, and as pets. Synthesis and applications . Our results greatly expand on what wildlife species are currently traded on the dark web and provide a baseline to track future changes. Given the low number of advertisements, we assume current conservation and biosecurity risks of the dark web are low. While wildlife trade is r ant on other layers of the Internet, particularly on e‐commerce and social media sites, trade on the dark web may still increase if these popular platforms are rendered less accessible to traders (e.g., via an increase in enforcement). We recommend focussing on surveillance of e‐commerce and social media sites, but we encourage continued monitoring of the dark web periodically to evaluate potential shifts in wildlife trade across this more occluded layer of the Internet.

Abstract: Species traits significantly influence pet trade dynamics, affecting demand, exploitation, and extinction risk. We examined the effect of species- and advertisement-level attributes on tarantula abundance and price in online markets, exploring rarely-considered fine-scale traits. Data from 977 ads showing 217 species and 81 ‘trade names’’ were collected from eight e-commerce websites located in six countries and analyzed using Structural Equation Models. Hairy, aggressive, and popular tarantulas were more abundant in commerce. Big, recently described species with ontogenetic changes in color and urticating hairs, with no evidence of captive breeding, had higher average price. Variability of prices in the ads were mainly explained by differences in website, lifestage and sex of the in idual advertised. After accounting for these drivers of market abundance and price, we found only weak evidence of direct price-rarity relationships, implying they are largely independently determined. This can have important implications for the future management and regulation of the international tarantula trade. Understanding consumer behavior in the pet trade is crucial for effective conservation efforts and we recommend using online ad data to track and understand supply and demand in tarantula trade. Leveraging marketing insights can enhance conservationists’ influence on consumers, promoting sustainable practices and benefit sharing for wildlife-dependent communities. Hobbyist communities may be the most strategic messenger for conservation messaging trying to reach consumers in the tarantula pet trade. Tarantula price and abundance in pet trade are shaped by species traits and advertisement attributes.
