“…Nevertheless, diversity in native shade trees can augment the presence of functional groups within the tea matrix (; Brady et al, 2011; Mudappa et al, 2014: p. 184; Moonen & Bàrberi, 2008) by providing additional support as refugia or as movement pathways by reducing canopy gaps (Vasudev & Fletcher, 2015), thus rendering the matrix more functional than just being a superficial green cover for some species. In fact, a diversity of native trees scattered within monoculture plantations has an enhanced positive effect on multiple groups of wildlife such as assemblages of bird guilds, bats, and certain soil arthropods (Marsden et al, 2020) such as spiders (Le Roux et al, 2018; Rubio et al, 2019) that are well‐known natural predators of tea pests (Raychaudhuri et al, 2016; Yinfang, 2004). Mammals such as leopards, elephants and other species who may be passive users of the tea landscape have shown to prefer higher density of ground cover (Kshettry et al, 2017; Mudappa et al, 2012; Yashmita‐Ulman et al, 2021) to avoid human interaction during movement between forest patches.…”

1. Despite their distinctive role in regulating agroecosystems, soil fauna is largely excluded from conservation action. With increasing evidence supporting matrix functionality as critical for multiple species in agroecosystems, it is important that efforts meant to enhance biodiversity in managed systems be inclusive and effective for all species and not just charismatic fauna. 2. Third party certifications are a popular mechanism for claiming pro-conservation practises in tropical agricultural lands. Therefore, we asked whether voluntary practises codified by third party certifications of tropical tea plantations support soil biodiversity, and what factors explain soil arthropod abundance and richness in such certified and uncertified landscapes.3. We used pitfall trap data and soil samples across two seasons in large tea plantations, and small tea-growing agroforestry farms in the Darjeeling Himalayas in India.Plantations certified and those not certified were selected for the study.4. Soil arthropod morphospecies abundance, richness and diversity were significantly higher in summer as opposed to winter. Contrary to our expectations, there was no significant difference in soil arthropod abundance, richness and diversity between uncertified small agroforestry farms and certified large monoculture plantations.Our analysis establishes tree species richness and season as the most important predictors of soil arthropod abundance, richness and effective number of species.5. We recommend that increased abundance and diversity of native trees in the tea matrix should be a crucial criterion for agroecosystem management. This would improve matrix functionality for species that are sensitive to management and reflect practises that enhance biodiversity.

“…Tea-dominated landscapes can support many forest-associated bat and bird species because they contain forest fragments and shaded areas ( Imboma et al, 2020 ). As part of a fragmented landscape, yerba mate and tea are perennial agroecosystems that provide habitat continuity for diverse arthropods ( Rubio et al, 2019 ). In a previous study, suitable habitats for tea plant cultivation and areas where these habitats overlap with the Asian elephant distribution to balance the conflict between the expansion of tea plantations and the spatial needs of wildlife in southwestern China were identified ( Dai, 2022 ).…”

Background Tea plantations support regional sustainable development and have the potential to support more biodiversity than urban open spaces. Numerous studies have shown the value of low-intensity agroecosystems for preserving biodiversity, however tea plantations have received less attention. The relationship between tea plantations and the diversity of macro-organisms, such as birds, is still not fully understood. Methods We investigated the bird diversity and vegetation conditions and calculated landscape metrics in 30 tea plantations in Anji County, Zhejiang Province, China. At these 30 sampling sites, we recorded 262 individuals belonging to 37 species, which were classified into two guilds: nature- and urban-dependent birds. We used cluster analysis to group the sampling sites based on the abundance of the birds. Then we evaluated the effects of associated plant diversity in tea plantations and the surrounding landscape composition on these bird guilds using species association computation and a generalized linear model. Results The results show that the maintenance of bird diversity by tea plantations benefits both nature- and urban-dependent birds. We found that landscape-scale factors surrounding the tea plantations mainly affected the bird richness due to their habitat selection. Landscape agglomeration and habitat quality were the dominant landscape-scale metrics. Patch-scale factors of tea plantations, especially the vegetation structure, had a strong influence on the abundance of the birds. Nature-dependent birds preferred to occur in tea plantations with perennial herbs, while urban-dependent birds were attracted by the general distributed plants, as annual herbs. Therefore, we concluded that tea plantations play an important role as a transitional zone between natural habitats and urban areas, thus reducing the impact of urbanization and maintaining bird diversity in low-quality habitats.

“…Batesian mimicry provides protection for Myrmarachne so they are able to have a wild habitat in the field [29]. Myrmarachne occupy a wide range of terrestrial habitats, including rainforests, shrubs, plants, grasses, fields, and even some man-made habitats [30][31][32][33]. Myrmarachne can, therefore, come into direct contact with ETOH.…”

An Ant-Mimicking Jumping Spider Achieves Higher Predation Probability with Lower Success Rate When Exposed to Ethanol

Ethanol (ETOH) affects many animals’ behaviour in nature; for example, honeybees become more aggressive after consuming ETOH. In previous studies, scientists have used honeybees and fruit flies as models to determine if they showed a strong preference to ETOH. Moreover, ETOH could affect their locomotion and learning abilities. However, whether and how ETOH affects spiders is unclear as of yet. In this study, we used empirical experiments to determine whether spiders showed preference for ETOH, as well as the potential benefits of spiders choosing ETOH, by using a common spider, Myrmarachne gisti, which has a high probability of contacting ETOH in their habitat. In our experiment, M. gisti showed a significant preference for ETOH. Although the success rate of the first attack was significantly decreased when M. gisti were exposed to ETOH, they had a significantly higher predation probability, since fruit flies also showed a significant preference for ETOH. Our findings suggested that ETOH could affect the prey capture efficiency of M. gisti, and indicated that spiders might evolve to use ETOH to locate a potential hunting place. Taken together, our findings suggested that M. gisti evolved to adapt to ETOH and could use it as a signal of the presence of food resources.
