“…Thus, microclimate conditions inside the leaf pocket are associated with the oil palm's understory. The results differed slightly from the previous study by Donfack et al (2021), which stated that the micro-temperature under oil palm stands reached its maximum at 03:00 pm. Another study by Hardwick et al (2015) showed that the maximum temperature understory of oil palm peaked at midday.…”

Abstract. Pradiko I, Farrasati R, Rahutomo S, Sapalina F, Pane RDP, Hidayat F, Ginting EN. 2022. The physical, chemical, and biological characteristics of microhabitats inside oil palm trunk axils in North Sumatra, Indonesia. Biodiversitas 23: 3793-3807. Above-ground ecosystems (AGE) components in oil palm plantations consist of epiphytic plants and fauna in microhabitat within the axil of pruned fronds. This research aimed to identify the characteristics of microhabitat, including microclimate profile, physical and chemical properties of the material deposit, epiphyte abundance, and microbe population. The study sites were located in the eastern and western regions of North Sumatra. Furthermore, vertical observations were taken on oil palm trunks at the height of 20, 100, 150, 200, and 300 cm. The study indicated that the microclimate, nutrients content, physical properties of the material deposit, and bacterial populations in the trunk axils of oil palm in the eastern differed from the western region. There was no obvious pattern in the microclimate profile for individual oil palms. However, there was a change in N, C-organic, and C/N ratios with the increasing height of microhabitat sites. In terms of abundance, Nephrolepis bisserata and Vittaria ensiformis epiphytes were more dominant in the upper and bottom trunk, respectively. The microhabitat at the bottom trunk had a denser bacterial population, negatively correlated with N, C-organic, C/N ratio, Mg, and pH.

“…Further, it implies that dissimilarity in abiotic conditions can directly or indirectly impact multiple taxa. The influence of vegetation structural complexity on multi-taxa diversity may act via altering light and microclimatic conditions 47 and other characteristics associated with variation in local planted tree species diversity and identity – with both shaping vegetation structural complexity 35 . Furthermore, the influence of tree islands on multi-taxa diversity might reflect the removal of environmental filtering associated with conventional management such as liming and fertilisation, which is responsible for biotic homogeneity in monoculture-dominated landscapes.…”

How to enhance biodiversity in monoculture-dominated landscapes is a key sustainability question that requires considering the spatial organization of ecological communities (beta diversity). Here, we experimentally tested if increasing landscape heterogeneity - through tree islands - is a suitable landscape restoration strategy when aiming to enhance multi-taxa diversity. We found that multi-taxa diversity resulted from islands fostering unique species (turnover: between 0.18 - 0.73) rather than species losses and gains (nestedness: between 0.03 - 0.34), suggesting that tree islands enhance diversity at the landscape scale. Through partial correlation networks, we revealed that landscape heterogeneity is associated with multi-taxa diversity (strength = 0.84). Soil biota were also central to the overall community by connecting beta diversity patterns across taxa. Our results show that increasing landscape heterogeneity enhances multi-taxa diversity in monoculture-dominant landscapes. Furthermore, we highlight that strategies aiming to enhance multi-taxa diversity should consider that spatial distributions of above- and below-ground communities are associated.

“…Communities made of shrubs and herbaceous plants serve as better windbreaks and more effectively fix sand [45]. In addition, their hydraulic traits may also allow for an increase in the richness indices [46] that improve resistance and resilience of the shrub community. For example, water use and sharing strategies are likely to differ among species [41][42][43].…”

“…Xu et al [45] suggested that greater species richness can buffer the adverse effects of soil drought, which may be one reason for improvements in resistance and resilience within the shrub community. It is also possible that with an increase in the number of species and individuals, the microclimate of the community changes such that transpiration increases, and climate drought conditions are alleviated [46]. Liu et al [26] also found that shrubs, such as Tamarix chinensis, are drought-resistant, salt-tolerant and sand-resistant, and adapt to a variety of ecological variations in the environment.…”

Changes in the resistance, recovery, and resilience of three desert riparian ecosystems to extreme droughts and the influence of ecological characteristics on them from 2000 to 2020 were analyzed within the Tarim River Basin, Xinjiang, China. The results showed that: (1) The resistance of the Populus euphratica forest community was the highest among the three plant communities. The recovery and resilience of the shrub community were the highest; (2) the resilience increased the most for the shrub community and decreased slightly for the Populus euphratica forest and herb communities as hydrological droughts waned; (3) the relative height and density significantly increased for Populus euphratica, decreased for herbs, and did not change for shrubs from 2000 to 2020; (4) the diversity indexes did not significantly change for the Populus euphratica forest and herb communities, and they increased for the shrub community from 2000 to 2020; (5) the resistance and resilience of the Populus euphratica forest, shrub, and herb communities were significantly affected by ecological characteristics, especially the Margalef richness index; and (6) the shrub community is more likely to rapidly recover (that is an increase of cover, height, and density) from future droughts in the Tarim River Basin, particularly with the implementation of new and more effective ecological restoration projects.
