“…different scenarios arising from different laboratories, uncertainty in time series), degree of knowledge of the analyzed species (number of occurrences), data quality, and parameter selection (Peterson et al 2018; Sillero et al 2021). However, the trend in predicted range loss for Mexican didelphid marsupials is evident and agrees with other studies (Ureta et al 2022; Lara-Díaz et al 2023).…”

“…We consider that M. nudicaudatus could be the most critically endangered species, since in addition to its restricted distribution and loss of area, it is a species with very specific feeding habits and behavior (Marineros et al 2016; Sosa-Bartuano 2016). While D. virginiana has habitat plasticity and dietary flexibility and can even be present in sites disturbed by humans (McRuer and Jones 2009; Luna-Jiménez et al 2021; Lara-Díaz et al 2023), it could represent a species of least concern compared to other didelphid marsupials from Mexico.…”

Climate change is one of the main threats to biodiversity in the 21st century. However, the effects that it may have on different mammal species are unknown, making it difficult to implement conservation strategies. In this paper, we used species distribution models (SDM) to assess the effect of global climate change on the potential distribution of the 8 of the 9 marsupial species in Mexico, and analyzed their distribution in the current system of natural protected areas (NPAs). We used presence records for each species and bioclimatic variables from the present and the future (2050 and 2080) with 2 contrasting possible scenarios (representative concentration pathways RCP 4.5 and 8.5). We found that Tlacuatzin canescens would have the most stable potential range under any climate change scenario, while the remaining species (Caluromys derbianus, Chironectes minimus, Didelphis marsupialis, D. virginiana, Philander opossum, Marmosa mexicana, and Metachirus nudicaudatus) would undergo notable range losses in the future, though there would not only be losses—according to our SDMs, for all species there would be some range gain under the different climate scenarios, assuming the vegetation cover remained. The current system of NPAs in Mexico currently protects and under the 2 future scenarios would protect less than 20% of the potential range of marsupials, so a reevaluation of their areas beyond the NPAs is highly recommended for the long-term conservation of this group. Our results provide relevant information on the estimated effects of global climate change on marsupials, allowing us to design more effective methodologies for the protection of this portion of the mammalian fauna in Mexico.

“…Several case-studies have highlighted the positive conservation outcomes of OECMs, ITs, and other types of community conservation areas in Latin America for threatened wildlife (O’Bryan et al, 2021; Boron et al, 2022; Devlin et al, 2023). In Mexico, carnivores are a major focus of current conservation strategies because many are keystone species and contribute to ecosystem functioning (Ripple et al, 2014), hold high cultural and economic value for Indigenous Peoples and Local Communities (IPLCs) (Garcia del Valle et al, 2015; Avila-Najera et al, 2018), and are experiencing rapid population declines (Lara Diaz et al, 2023). In light of expanding human populations and increased human-wildlife interactions, conflicts are intensifying throughout Mexico’s conservation estate, necessitating more efforts to promote coexistence between humans and carnivores (Anaya-Zamora et al, 2017; Flores-Armillas et al, 2020).…”

Area-based conservation remains a pivotal component of global wildlife protection efforts. Mexico hosts a diverse array of area-based approaches, encompassing protected areas (PAs) and other effective area-based conservation measures (OECMs) such as voluntary conservation areas (VCAs) and wildlife management units (UMAs). Indigenous Territories (ITs) also provide heightened conservation potential through traditional ecological knowledge systems. These conservation spaces exhibit significant variations in community involvement, national coverage, and governance. Here, we evaluate the conservation potential of these land management types for 29 terrestrial carnivores, focusing on spatial co-occurrence. We determine areas in Mexico lacking area-based protection and calculate carnivore richness per land management type. Analyzing overlap between land management types and carnivore ranges, we employ heat maps to visualize overlap occurrence and key unprotected areas. We found that across all carnivore ranges, 87% of the area remains unprotected under designated protection areas (PAs & VCAs), decreasing to 65.2% after including non-designated types (ITs and UMAs). We identified several key gaps in the protection estate for Mexican carnivores, most notably on the eastern Mexican coast in the state of Veracruz. Our findings corroborate the importance of including Indigenous Peoples and Local Communities in conservation efforts, emphasizing their contributions to the stewardship of Mexican ecosystems. As the global protected area estate continues to expand under the post-2020 global biodiversity targets, and the importance of a well-designed and diverse portfolio of practices for conservation is recognized, the need for collective action, increased collaboration and inclusivity, and effective communication amongst stakeholders become necessary for carnivore conservation.
