Abstract: Habitat loss and degradation can undermine wildlife communities and ecosystem functioning. However, certain generalist wildlife species like mesopredators and omnivores can exploit these disturbed habitats, sometimes leading to population increases (e.g. ‘mesopredator release’ in degraded areas). Although mesopredator release may cause negative effects on food webs and zoonotic disease management, some disturbance‐tolerant species may help perpetuate important ecological interactions, such as seed dispersal. We evaluated the habitat associations of common palm civets Paradoxurus hermaphroditus , which are widespread generalist mesopredators in Southeast Asia. Common palm civets are also high‐quality seed dispersers, and potential zoonotic disease hosts. We used published and new camera trapping data to map their probability of presence across Southeast Asia and evaluate regional‐scale associations between capture rates and habitat variables such as elevation, ecoregion intactness and Human Footprint Index, among others. We also assessed the influence of habitat variables on their relative abundance at the local scale. At the regional scale, we found that common palm civets showed significant positive associations with landscapes characterized by lower ecoregion intactness, higher Human Footprint Index and lower elevations. At the local scale, their relative abundance showed a significant positive association with higher Human Footprint Index, but only to a certain point, after which it started decreasing. They also favoured lower elevations at the local scale. These multi‐scale results indicate that common palm civets' abundance can increase under certain levels of human disturbances, consistent with the ‘mesopredator release’ hypothesis. This suggests they may be crucial seed dispersers in degraded forest landscapes, especially where more sensitive seed dispersers have disappeared. Our results are also consistent with previous studies reporting that habitat degradation increases populations of potential zoonotic disease hosts, and thus risks of transmission to humans.

Abstract: This book examines the rules and mechanisms of international law relevant to the suppression of state organized crime, and provides a normative justification for developing international legal mechanisms specifically designed to address this phenomenon. State organized crime refers to the use by senior state officials of the resources of the state to facilitate or participate in organized crime, in pursuit of policy objectives or personal profit. This concept covers erse forms of government misconduct, including partnerships with organized criminal groups involved in drug trafficking, the plundering of a country’s resources by kleptocratic rulers, and high-level corruption schemes. The book identifies the distinctive criminological characteristics of state organized crime, and analyses the applicability, potential, and limits of the norms and mechanisms of international law relevant to the suppression of state organized crime. In particular, it discusses whether the involvement of state organs or agents in organized crime may amount to an internationally wrongful act giving rise to the international responsibility of the state, and highlights a number of practical and normative shortcomings of the legal framework established by relevant crime-suppression conventions. The book also sketches proposals to develop an international legal framework designed to hold perpetrators of state organized crime accountable. It presents a normative justification for criminalizing and suppressing state organized crime at the international level, proposes draft provisions for an international convention for the suppression of state organized crime, and discusses the potential role of the UN Security Council and of international criminal courts and tribunals, respectively, in holding perpetrators accountable.

Abstract: As long as distinct legal regimes apply to international and non-international armed conflicts, the determination of the nature of the conflict by a court of law directly impacts on the criminal responsibility of the accused for war crimes. As this article shows, the approach traditionally used in international criminal law to characterise mixed conflicts is not sufficiently reliable for the addressees of penal norms. Low-ranking perpetrators have generally little chance of being aware of the international character of the conflict. This article argues that the principle of in idual guilt requires establishing the mens rea regarding the nature of the conflict. Accordingly, a mistake of fact, or alternatively, a mistake of legal element should be admissible defences. Furthermore, it is submitted that both the method of conflict characterisation and the definition of the corresponding mental element are not compatible with the requirements of the principle of legality.

Abstract: This article discusses the offence of participation in a terrorist group or conspiracy under French law, as applied by the French criminal justice system to prosecute and convict in iduals who travel or attempt to travel abroad to participate in armed jihad. In light of a critical assessment of decisions rendered by French courts in cases involving jihadi fighters, it proposes to reflect on the orientation of the criminal law in matters relating to the participation of European nationals in armed jihad in foreign territory. Expressing concern over the excessive reach of substantive criminal-law provisions and of related prosecutorial policies, the article argues that the current legal framework and newly proposed legislation no longer serve the legitimate objective of protecting public order and safety from a tangible threat, and that the criminal law is at risk of becoming a tool of ideological warfare against designated enemies of the state.

Abstract: Southeast Asia supports the greatest ersity of felids globally, but this ersity is threatened by the severe forest loss and degradation occurring in the region. The response of felids to disturbances appears to differ depending on their ecology. For ex le, the largely terrestrial and nocturnal leopard cat ( Prionailurus bengalensis ) thrives near forest edges and in oil palm plantations where it hunts rodents (Muridae) at night, thereby avoiding human activity peaks. Conversely, we hypothesized that the sympatric and similar‐sized marbled cat ( Pardofelis marmorata ) would respond negatively to edges and relatively open oil palm plantations as they are more arboreal than leopard cats, rely on tree connectivity for hunting, and are diurnal so have less potential to temporally avoid humans. We used camera trapping from Southeast Asia to test habitat associations at multiple spatial scales using zero‐inflated Poisson generalized linear mixed models and hierarchical occupancy modeling. We found that marbled cats were positively associated with large intact forests and, in contrast to leopard cats, negatively associated with oil palm plantations. Furthermore, we found preliminary evidence suggesting marbled cats may adapt their diel activity to become more crepuscular in degraded forests, likely shifting their activity to avoid humans. These findings suggest that the marbled cat's International Union for Conservation of Nature (IUCN) Red List conservation status should potentially be upgraded from Near Threatened to Vulnerable, matching other forest‐dependent felids in the region. We posit our findings may be generalizable such that semi‐arboreal and diurnal felids could face greater threats from habitat degradation than their terrestrial and nocturnal relatives.

Abstract: Habitat loss and degradation threaten forest specialist wildlife species, but some generalist mesopredators exploit disturbed areas and human‐derived food, which brings them into closer contact with humans. Mesopredator release is also important for human health for known zoonotic disease reservoirs, such as Asian civets (Viverridae family), since this group includes the intermediator species for the SARS‐CoV‐1 outbreak. Here we use camera trapping to evaluate the habitat associations of the widespread banded civet ( Hemigalus derbyanus ) across its range in Southeast Asia. At the regional scale, banded civet detections among published studies were positively associated with forest cover and negatively associated with human population. At the local scale (within a landscape), hierarchical modeling of new camera trapping showed that abundance was negatively associated with forest loss and positively associated with distance to rivers. These results do not support mesopredator release and suggest a low likelihood overlap with humans in degraded habitats and, therefore, a low risk of zoonotic disease transmission from this species in the wild. We also estimate that banded civet distribution has contracted to under 21% of its currently recognized IUCN Red List range, only 12% of which falls within protected areas, and a precipitous recent decline in population size. Accordingly, we suggest the banded civet's Red List status should be re‐evaluated in light of our findings.
