ABSTRACT
Context: Globally, forest landscapes are rapidly transforming, with the role of institutions as mediators in their use and management constantly appearing in the literature. However, global comparative reviews to enhance comprehension of how forest management institutions (FMIs) are conceptualized, and the varying determinants of compliance, are lacking. And so too, is there knowledge fragmentation on the methodological approaches which have and should be prioritized in the new research agenda on FMIs. Objectives: We review the regional variations in the conceptualization of FMIs, analyze the determinants of compliance with FMIs, and assess the methodological gaps applied in the study of FMIs. Methods: A systematic review of 197 empirically conducted studies (491 cases) on FMIs was performed, including a directed content analysis. Results: First, FMIs literature is growing; multi-case and multi-country studies characterize Europe/North America, Africa and Latin America, over Asia. Second, the structure-process conceptualization of FMIs predominates in Asia and Africa. Third, global south regions report high cases of compliance with informal FMIs, while non-compliance was registered for Europe/North America in the formal domain. Finally, mixed-methods approaches have been least employed in the studies so far; while the use of only qualitative methods increased over time, the adoption of only quantitative approaches witnessed a decrease. Conclusion: Future research should empirically ground informality in the institutional set-up of Australia while also valorizing mixed-methods research globally. Crucially, future research should consider multidisciplinary and transdisciplinary approaches to explore the actor and power dimensions of forest management institutions.

ABSTRACT
The information available on the diversity of ant species and their distribution and interaction with forest health in Nepal remains limited. As part of a nationwide project on forest health, we conducted inventories to assess the diversity and distribution of forest ants and their role in forest management in Nepal. Ants were collected from 187 plots of 10 m × 10 m size along the north-south belt transects in eastern, central, and western Nepal. We used vegetation beating, sweeping, and hand collection methods in selected forest types. In each transect, we designed six plots in each major forest type (Sal, Schima-Castanopsis, and broadleaf mixed forests) and three plots each in deodar, Alnus, riverine, and Cryptomeria forests. We recorded 70 ant species from 36 genera and six subfamilies. This includes five genera and nine species new for the country, as well as eight tramp species, four of which are major ecological, agricultural, and/or household pests. Our study indicates that forest ant species richness is high in western Nepal and the Siwaliks, and it decreases as elevation increases. The high diversity of ant species in the forests of Nepal needs to be assessed with further exploration using multiple sampling methods covering all seasons and forest types. Ants can be useful indicators for ecosystem management and human impacts on forests. Reports of invasive ants in Nepalese forests indicate the relevance of urgent interventions through sustainable forest management initiatives to prevent future incursions.
