“…Starting from Rosenzweig's classic works, ecological scholars have placed special emphasis on the study of species distribution [24][25][26], which has carried on into the field of biodiversity conservation [27,28]. Wildlife hunting in Southeast Asia has existed for thousands of years [29,30], providing raw materials for traditional medicine, pets, handicrafts, etc. [31][32][33], which may alter regional species composition [34].…”

Myanmar is located in the Indo-Burma biodiversity hotspot, but lacks understanding of the bio-diversity hotspots and protected areas within its borders. Climate change affects the effective-ness of protected areas and the potential distribution range of species. Based on Myanmar's re-gional characteristics, endangered status, and representativeness, this paper selects species and identifies biodiversity hotspots using the MaxEnt model. We studied the biodiversity within the terrestrial protected area network in Myanmar, as well as the potential for cross-boundary range shifts among protected areas under different climate scenarios. Species populations outside My-anmar's protected area network may not be able to find suitable habitats in the future, further exacerbating climate-related extinction risks. Additionally, some protected areas in Myanmar may not be fully utilizing their biodiversity representation potential, and with scientific spatial planning, Myanmar's protected areas could support a large number of species. In the context of continued warming, identifying new protected areas that encompass the future and current climatic niches of protected areas can increase the capacity for sustained biodiversity conservation. We hope that this study provides insights for increasing the effectiveness of Myanmar's protect-ed area network and emphasizes the urgency of coordinated protection of protected areas and biodiversity hotspots.

Animal trafficking and poaching pose significant threats to global biodiversity, causing irreversible ecological, economic, and social consequences. The illegal trade in wildlife, encompassing both live animals and their body parts, is a lucrative enterprise driven by demand for exotic pets, luxury goods, traditional medicine, and trophy hunting. This multi-billion-dollar industry exploits vulnerable species, pushing many towards the brink of extinction. Loss of keystone species disrupts natural food chains, alters vegetation dynamics, and diminishes biodiversity, thereby compromising the overall stability of ecosystems. Animal trafficking and poaching represent grave threats to global biodiversity, jeopardizing the ecological integrity of ecosystems and the well-being of human societies. The present article provides a comprehensive overview of the detrimental impacts of these illicit activities on wildlife populations and ecosystems.

How Do We Identify Anthropogenic Allee Effects in the Wildlife Trade?

The harvest and sale of wildlife can drive species to extinction when consumers are willing to pay high prices for the last harvested individuals of a very rare species, a phenomenon known as the anthropogenic Allee effect (AAE). Because demand for rarity is an inherent human desire, the AAE has the potential to affect a wide range of exploited species across several geographic regions. Here, we assess the current extent of empirical evidence for the AAE, how such evidence has been measured, and how this evidence interfaces with existing models of the AAE. We find substantial gaps in the empirical evidence base for the AAE and suggest that this deficit prevents assessment of the AAE in species extinctions. We provide a framework for generating empirical evidence that can identify when the AAE is likely occurring or has the potential to occur in the future, and recommend directions for both empirical and theoretical modeling research designed to strengthen our ability to forecast the ecological and market conditions that result in an AAE.
