Nepenthes pitcher plants produce modified jug-shaped leaves to attract, trap and digest insect prey. We used 16S rDNA cloning and sequencing to compare bacterial communities in pitcher fluids of each of three species, namely Nepenthes ampullaria, Nepenthes gracilis and Nepenthes mirabilis, growing in the wild. In contrast to previous greenhouse-based studies, we found that both opened and unopened pitchers harbored bacterial DNA. Pitchers of N. mirabilis had higher bacterial diversity as… 
Comparative Study of Bacterial Communities in Nepenthes Pitchers and Their Correlation to Species and Fluid Acidity
TLDR
A unique microbial community structure was found in Nepenthes ampullaria which could reflect their adaptation to digest leaf litter, in addition to insect prey and provides insights into their community structure in this unique ecological system.
Bacterial Diversity and Community Structure in Two Bornean Nepenthes Species with Differences in Nitrogen Acquisition Strategies
TLDR
Nitrogen-fixing bacteria were present in both study species, which might provide essential nutrients to the plant at times of low prey capture and/or rare encounters with bats.
acterial diversity and composition in the fluid of pitcher plants of the enus
TLDR
The diversity of bacterial communities was assessed in Nepenthes pitcher fluids and the composition of the bacterial community was compared to that in other environments, including the phyllosphere of Arabidopsis, animal guts and another pitcher plant, Sarracenia.
Dipteran larvae and microbes facilitate nutrient sequestration in the Nepenthes gracilis pitcher plant host
TLDR
It is shown that niche segregation occurs between phorid and culicid larvae, with the former fragmenting prey carcasses and the latter suppressing fluid microbe levels, and that pitcher communities facilitate nutrient sequestration in their host.
In Situ Proteolytic Activity in Nepenthes gracilis Pitcher Plant Traps Is Affected by Both Pitcher-Extrinsic and Pitcher-Intrinsic Factors
TLDR
The findings confirm that in situ proteolytic activity of Nepenthes pitcher fluids varies significantly with extrinsic factors and suggest that nepenthesin secretion may be subject to multiple regulation mechanisms.
Convergence between the microcosms of Southeast Asian and North American pitcher plants
TLDR
Using samples from more than 330 field-collected pitchers of eight species of Southeast Asian Nepenthes and six species of North American Sarracenia, it is demonstrated that the pitcher microcosms, or miniature ecosystems with complex communities, are strikingly similar.
Proteome analysis of digestive fluids in Nepenthes pitchers.
TLDR
Nepenthes pitcher plants have evolved an arsenal of enzymes to digest prey caught in their traps and the panel of new proteins identified in this study provides new insights into the digestive process of these carnivorous plants.
Fluid physico-chemical properties influence capture and diet in Nepenthes pitcher plants.
TLDR
In addition to viscoelasticity, the pitcher's fluid acidity and wetting ability influence the fate of insects and hence the diet of Nepenthes.

Local and Regional‐Scale Food Web Structure in Nepenthes alata Pitchers 1
TLDR
Individual pitchers harbored relatively simple communities despite the regional species richness, and only limited kinds of predator-prey encounters seemed to occur frequently in the regional food web.
Culturable Bacteria Present in the Fluid of the Hooded-Pitcher Plant Sarracenia Minor Based on 16S rDNA Gene Sequence Data
TLDR
The culturable microbial community within the pitcher fluid of 93 Sarracenia minor carnivorous plants was examined over a 2-year study and species–area curves suggest that sampling efforts were sufficient to recover a representative culturable bacterial community.
Secreted pitfall-trap fluid of carnivorous Nepenthes plants is unsuitable for microbial growth.
TLDR
The results reveal that Nepenthes pitcher fluids represent a dynamic system that is able to react to the presence of microbes and can avoid and control the microbial colonization of their pitfall traps and, thereby, reduce the need to vie with microbes for the prey-derived nutrients.
Proteome analysis of pitcher fluid of the carnivorous plant Nepenthes alata.
TLDR
The genus Nepenthes comprises carnivorous plants that digest insects in pitcher fluid to supplement their nitrogen uptake, and proteins involved in prey digestion are identified, most of which are designated "pathogenesis-related proteins".
Chemical composition of epicuticular wax crystals on the slippery zone in pitchers of five Nepenthes species and hybrids
TLDR
The compositions and micromorphologies of the wax crystals of five Nepenthes species and hybrids were analysed in order to test whether the chemical principles underlying this ecological function are widespread within the genus.
Evidence for alternative trapping strategies in two forms of the pitcher plant, Nepenthes rafflesiana
TLDR
The present results show that pitcher plants utilize several mechanisms for prey capture and retention, varying in efficiency and relative importance between forms, and it is proposed that these differences represent alternative prey capture strategies that may provide a mechanism to reduce competition and facilitate species co-existence in nutrient-limited habitats.
Slippery or sticky? Functional diversity in the trapping strategy of Nepenthes carnivorous plants.
TLDR
Investigating whether Nepenthes species exhibit diverse trapping strategies and measuring the amount of slippery wax on the pitcher walls of 23 taxa and the viscoelasticity of their digestive liquid and compared their retention efficiency on ants and flies suggested the possibility of an investment trade-off for the plants.
A viscoelastic deadly fluid in carnivorous pitcher plants.
TLDR
The viscoelastic trap constitutes a cryptic but potentially widespread adaptation of Nepenthes species and could be a homologous trait shared through common ancestry with the sundew (Drosera) flypaper plants.
The Development of the Digestive Glands and Enzymes in the Pitchers of Three Nepenthes Species: N. alata, N. tobaica, and N. ventricosa (Nepenthaceae)
TLDR
Results indicate that the genus Nepenthes digestive glands are capable of producing a wide range of digestive enzymes both during and after pitcher development, and are thus functionally carnivorous.
