“…Drought vulnerable species are typically missing [20]. As with oil palm plantations, increased management intensities have a negative influence on epiphyte assemblages in both coffee plantations [21, 22] and ancient tea gardens [23]. Vascular and non-vascular epiphytes have also been studied in monoculture plantations of, for example, Eucalyptus, Quercus, Araucaria and Pinus [8, 24, 25].…”

The ongoing destruction of old-growth forests puts tropical forest species under great pressure because of the resulting loss of habitat. An important biotic component of these forests are vascular epiphytes, which structurally depend on trees. In human-modified landscapes potential hosts may still be present, e.g. in the form of isolated remnant trees, small groups of planted trees, in patches of secondary forests, or in plantations. For this study, we assessed the potential of timber monocultures and secondary forest patches to function as refuges for vascular epiphytes. We studied epiphyte assemblages in teak and pine plantations and secondary forest patches of unknown age along a rainfall gradient (1100-4200 mm) at the Pacific coast of western Panama and also in a few oil palm plantations. Invariably, rainfall had the expected positive influence on epiphyte diversity and abundance. Individual-based rarefaction curves showed that species richness was significantly lower in timber and oil palm plantations compared to secondary forest patches, which in turn hosted less species-rich epiphyte assemblages than (cultivated and wild grown) pasture trees from the same study region. Our results suggest that the value of timber and oil palm plantations as refuges for vascular epiphytes in human-modified landscapes is limited. Secondary forest patches were more promising in that regard.

“…We found forest tea plantations harbored a greater diversity of all arthropods, natural enemies, and insect herbivores than monoculture tea plantations. Previous work demonstrated that vegetation communities of the forest tea plantations are similar to natural forests including herbs, shrubs, vines, and epiphytes, while the monoculture tea plantations are dominated by herbs without trees (Qi et al 2013). Vegetation complexity including structural complexity and plant species diversity may increase the arthropod diversity by creating environmental heterogeneity and resource availability (Li et al 2019).…”

“…Forest tea plantations, also referred to as ancient tea plantations, have a long tradition history in Menghai, Yunnan Province, southwest of China, and likely dates back to the Tang Dynasty (800 yr ago; Qi et␣al. 2013). Different from the monoculture tea plantations which are dwarf shrubs (about 1 m high), the ancient tea trees (about 4 m high) have grown for hundreds of years in mixed stands with many native trees, resulting in a landscape deemed “forest tea plantation” (Fig.…”

Effects of different tea plantation management systems on arthropod assemblages and network structure

Tea plantations are intensive monocultures and vulnerable to various pests due to a low diversity of natural enemies. In ancient tea plantations, the trees have grown for hundreds of years in mixed stands with many native trees, resulting in a landscape deemed as a "forest tea plantation." However, no empirical studies have explicitly examined the effects of forest tea plantations on arthropod communities. Here, we addressed the difference of arthropod assemblages and ecological networks between the forest tea plantations and monoculture tea plantations, specifically focusing on the natural enemies and insect herbivores. Our results showed that the diversity of all arthropods, insect herbivore, and their natural enemies was higher in forest tea plantations compared to the monoculture tea plantations. In contrast, monoculture tea plantations had a higher abundance of all arthropods and insect herbivores due to a sharp increase in the abundance of the pest leafhopper, Empoasca vitis. Furthermore, forest tea plantation had higher co-occurrences among natural enemies and insect herbivores than a randomized network, which suggests that natural enemies may co-occur with some specific herbivore species. These results allow us to predict that forest tea plantations enhance insect herbivore control by increasing diversity of natural enemies and network structure between natural enemies and herbivores. Our study suggests that the ecological network approach opens up new possibilities for improving our prediction and understanding of pest suppression in agroecosystems.

“…Pu-erh tea is defined as a geographical indication product by the General Administration of Quality Supervision, Inspection, and Quarantine of the People’s Republic of China (GB/T 22111-2008), and is one of the most popular tea beverages in Asian countries; in particular, southwestern China and South Asian countries attribute this to its unique flavors and beneficial effects on human health [ 1 ]. It is processed from the sun-dried green tea leaves and can be classified into ancient tea (Gu-shu cha, AT) and terrace tea (Tai-di cha, TT) based upon the source of raw material [ 2 , 3 ]. AT is collected from ancient tea gardens that have good economic and ecological efficiencies such as climate regulation, water and soil conservation whereas TT is gathered from terrace tea plantations that rely on the good management of tea fields including fertilization, pruning, and pesticide spraying.…”

Pu-erh tea processed from the sun-dried green tea leaves can be divided into ancient tea (AT) and terrace tea (TT) according to the source of raw material. However, their similar appearance makes AT present low market identification, resulting in a disruption in the tea market rules of fair trade. Therefore, this study analyzed the classification by principal component analysis/hierarchical clustering analysis and conducted the discriminant model through stepwise Fisher discriminant analysis and decision tree analysis based on the contents of water extract, phenolic components, caffeine, and amino acids, aiming to investigate whether phytochemicals coupled with chemometric analyses distinguish AT and TT. Results showed that there were good separations between AT and TT, which was caused by 16 components with significant (p < 0.05) differences. The discriminant model of AT and TT was established based on six discriminant variables including water extract, (+)-catechin, (−)-epicatechin, (−)-epigallocatechin, theacrine, and theanine. Among them, water extract comprised multiple soluble solids, representing the thickness of tea infusion. The model had good generalization capability with 100% of performance indexes according to scores of the training set and model set. In conclusion, phytochemicals coupled with chemometrics analyses are a good approach for the identification of different raw materials.
