“…The reliability of the literature for population assessment is poor (Berryman et al 2023), especially concerning species with minimal information, such as the snoring rail. The population of endemic species will also bring new information about the distribution (Zulkarnaen et al 2022). Consequently, there is a necessity for enhanced fieldwork and data collection methods in future surveys to address the least information about the population and distribution.…”

This study focuses on assessing the critically endangered mandar dengkur, or snoring rails (Aramidopsis plateni Blasius 1886), within Indonesia's Gandang Dewata National Park. Despite its importance in regional biodiversity, the species remains poorly documented. The primary objectives of this research are to investigate the population and ecological role of the mandar dengkur in Gandang Dewata National Park. It aims to understand their population status, the factors influencing their survival, and the level of global threats facing this species. Field surveys from July to August 2023 employed point counts and interviews with local residents, revealing a population of 20 snoring rails. Tondok Bakaru was identified as the primary subpopulation, with the highest count and probability of occurrence. Tondok Bakaru, characterized by remote and isolated areas, plays a crucial role in snoring rails' survival, mirrored by discoveries of other sensitive species like the Anoa. Environmental variables analysis through Generalized Linear Modeling (GLM) identified the nearest food source and settlement as significant factors influencing snoring rail populations, aligning with their elusive nature. The selected GLM model highlighted the impact of average NDVI, distance to the nearest food source, and distance to the nearest settlement on snoring rail density, guiding conservation efforts. This study underscores the urgency of upgrade the snoring rails' conservation status to Endangered (EN) and implementing global conservation measures by improving data collection with technology.

ARTICLE HIGLIGHTS- The palm genus Pinanga is the most diverse in Southeast Asia. - Limited ecological studies on Pinanga show the influence of environmental factors.- High Pinanga endemism in Borneo requires conservation action.ABSTRACTPalms represent some of the keystone species in tropical forests, providing numerous ecosystem services. They are widely studied by botanists because of their iconic and majestic appearance, although ecological studies of palm abundance, distributions, and diversity have only recently begun to gain attention. The abundance and diversity of palms at different spatial scales can be influenced by various factors, such as climate, soil properties, hydrology, topography and forest structure; understanding these influences is essential for conservation. This review details four abiotic factors (climate, soil chemistry, hydrology and topography) and one biotic factor (forest structure) affecting palm distribution and diversity. The genus Pinanga, one of the most diverse genera of palms, is discussed in terms of its distribution and diversity in Southeast Asia. Ecological studies on Pinanga diversity in the region are examined, revealing the influence of micro- and macro-scale variation in environmental factors, such as litter depth and thickness, canopy openness and crown cover, elevation, slope, aspect, light intensity, humidity and air temperature. The existing knowledge gaps on Pinanga ecology in Southeast Asia are discussed, and the need for more studies on population structures, functional traits and determinants of Pinanga diversity and distributions within different lowland forest types in the region are highlighted. The high endemism shown by Pinanga necessitates a more comprehensive ecological understanding of this genus to better inform its conservation and protection.
