Abstract

The expansion of agricultural and plantation areas, and demands for improved accessibility, particularly on gentler slopes, has accelerated deforestation in West Sumatera. This study investigates changes in forest cover in West Sumatera over the period from 2000 to 2050, using two initial cover datasets from 2000 and 2015. We used driving variables, including elevation, slope, and roads, processed through the Change Modeller in IDRISI TerrSet. Modelling results indicate that forest cover changes are significantly influenced by topography, with gentler slopes experiencing faster rates of deforestation compared to steeper areas. Regions with flat land and easy access are particularly vulnerable to large-scale conversion for agricultural use, especially for palm oil plantations. The results underscore the interplay between infrastructure development and forest cover changes, highlighting the need for careful consideration of environmental impacts in planning and policy making. This study urges the policymakers to implement strategic spatial planning and land-use monitoring to mitigate impacts of deforestation to ensure forest sustainability in West Sumatera.

Abstract

Human activity is a major factor in the decline of primate biodiversity, including long-tailed macaques, which thrive in varied habitats, even near human settlements. This overlap can lead to conflicts for both humans and macaques. The objective of this study is to determine the distribution of long-tailed macaques through direct observation and potential distribution based on habitat suitability modelling using MaxEnt. Six environmental variables were selected based on the ecological traits of long-tailed macaques, including forest cover, population density, distance to roads, distance to forests, distance to conservation areas, and land use type. Moreover, 32 coordinate points were identified in Padang for locating long-tailed macaque and modelled using MaxEnt. The results indicate that long-tailed macaques are primarily distributed in areas with forest cover but are close to anthropogenic activities. The modelling reveals that the habitat suitability for this species in Padang tends to be low to moderate. The environmental variables that exert the most significant influence on their distribution are distance to roads and forest cover (53.3% and 20.1% respectively). Consequently, areas with a higher potential of habitat suitability required particular attention to manage conflicts and populations to avoid potential negative impacts that could arise.

Abstract

Insects dominate the animal kingdom, comprising nearly 80% of all animal species, with around 250,000 species found in Indonesia. Among these, stingless bees are a diverse group with over 60 genera. Some stingless bees are cultivated in meliponiculture, practiced around homes and plantations. This study aimed to assess insect diversity near stingless bee colonies in the Education Farm (Edufarm), Universitas Andalas, through a rapid assessment conducted over two days in May 2024. A transect was established with three U-shaped sub-transects surrounding a stingless bee colony. The modify quadra protocol sampling (honey bait traps, leaf litter, soil cores, and hand collecting) was used around the colony. The study identified 1153 individuals from 6 orders, 9 families, and 15 species of insects, with Formicidae from Hymenoptera being the most dominant. This research offers valuable insights into insect diversity around stingless bee colonies at Edufarm and can inform better management strategies for stingless bees and the ecological structure of surrounding environments.
