Nepenthes pitcher plants trap prey in specialized leaves formed into pitchers. Most lowland species live in open, sunny habitats and capture prey to obtain nutrients, principally nitrogen (N). Nepenthes ampullaria is commonly found under closed canopy forest and possesses morphological traits that indicate adaptation to trap leaf litter as a nutrient source. We tested this hypothesis by comparing foliar stable N isotope abundance (δ15N) between plants growing under forest canopy at 20 sites… 
Nutritional benefit from leaf litter utilization in the pitcher plant Nepenthes ampullaria.
The data indicate that N. ampullaria benefits from leaf litter utilization and this study provides the first experimental evidence that the unique nitrogen sequestration strategy of N. Ampullaria provides benefits in term of photosynthesis and growth.
Tree shrew lavatories: a novel nitrogen sequestration strategy in a tropical pitcher plant
It is tested the hypothesis that tree shrew faeces represent a significant nitrogen (N) source for N. lowii, finding that it accounts for between 57 and 100 per cent of foliar N in mature N.Lowii plants.
A Carnivorous Plant Fed by Its Ant Symbiont: A Unique Multi-Faceted Nutritional Mutualism
The carnivorous plant Nepenthes bicalcarata grows in the Bornean peatswamp forests and is believed to have a mutualistic relationship with its symbiotic ant Camponotus schmitzi, which contributes crucially to the nutrition of N. bical carata via protection of assimilatory organs, enhancement of prey capture, and myrmecotrophy.
Effects of arthropod inquilines on growth and reproductive effort among metacommunities of the purple pitcher plant (Sarracenia purpurea var. montana)
This work evaluates the relationship between the communities that colonize pitcher plant phytotelmata and the pitcher plants’ vegetative growth and flower production to better understand the symbiotic role played by phytOTelma communities.
Incorporating ecological context: a revised protocol for the preservation of Nepenthes pitcher plant specimens (Nepenthaceae).
The value of ecological information in distinguishing between controversial montane Bornean taxa is demonstrated and a revised protocol for the collection and preparation of Nepenthes specimens is provided, designed to maximise the amount of ecologicalInformation retained in herbarium material.
A Novel Type of Nutritional Ant–Plant Interaction: Ant Partners of Carnivorous Pitcher Plants Prevent Nutrient Export by Dipteran Pitcher Infauna
It is discovered that C. schmitzi ants not only increase the pitchers' capture efficiency by keeping the pitchers’ trapping surfaces clean, but they also reduce nutrient loss from the pitchers by predating dipteran pitcher inhabitants (infauna).
Adaptive radiation with regard to nutrient sequestration strategies in the carnivorous plants of the genus Nepenthes
It is shown that the plant benefits from nitrogen uptake by increased rate of photosynthesis and growth what may provide competitive advantage over others co-habiting plants and a possible impact of such specialization toward hybridization, an important mechanism in speciation is discussed.
The plant-ant Camponotus schmitzi helps its carnivorous host-plant Nepenthes bicalcarata to catch its prey
A positive effect of C. schmitzi on both prey intake and breakdown is suggested, suggesting this ant–plant interaction could be a nutritional mutualism involving the unusual association of carnivory and myrmecotrophy.
A carnivorous sundew plant prefers protein over chitin as a source of nitrogen from its traps.


Termite Prey Specialization in the Pitcher Plant Nepenthes albomarginata—Evidence from Stable Isotope Analysis
N. albomarginata showed higher δ13C values and a lower estimated intercellular partial pressure of CO2(Ci) than N. rafflesiana, indicating either higher water use efficiency (due to water stress) or greater photosynthetic capacity, and the carbon stable isotope abundance in both species was investigated.
The nitrogen supply from soils and insects during growth of the pitcher plants Nepenthes mirabilis, Cephalotus follicularis and Darlingtonia californica
The data suggest complex patterns of partitioning of insect and soil-derived N between source and sink regions in pitcher plants and possibly higher dependence on insect N than recorded elsewhere for Drosera species.
Effects of leaf litter species on macroinvertebrate community properties and mosquito yield in Neotropical tree hole microcosms
Investigation of the effects of leaf litter from Ceiba pentandra, Dipteryx panamensis, Ficus yoponensis, and Platypodium elegans on macroinvertebrate species composition, richness, and abundance in artificial water-filled tree holes in a lowland moist forest of Panama suggests differences in nutritional quality among litter species can be attributed to differences in nutrients.
Morphological correlates of necromass accumulation in the traps of an Eastern tropical pitcher plant, Nepenthes ampullaria Jack, and observations on the pitcher infauna and its reconstitution following experimental removal
Abstract I studied the trap morphology, necromass accumulation rates and pitcher infauna of an eastern tropical pitcher plant, Nepenthes ampullaria, that grew in `kerangas' heath forest in the Sungei
Carnivory in the Bromeliad Brocchinia reducta, with a Cost/Benefit Model for the General Restriction of Carnivorous Plants to Sunny, Moist, Nutrient-Poor Habitats
A cost/benefit model for the evolution of carnivory is developed to analyze why carnivorous plants are restricted mainly to sunny, moist, nutrient-poor sites and seasons, and why carnivory are rare in epiphytes and other bromeliads.
Prey spectra of bornean nepenthes species (Nepenthaceae) inrelation to their habitat
Examination ofpitcher prey contents of 18 Bomean pitcher plants showed that pitchers attract 17 fauna groups, and pitchers collected below 100 m altitude contained enormous numbers of ants but their number generally decreased with altitude.
Nutrient Retention by the Root Mat of an Amazonian Rain Forest
First evidence supporting the ability of the root map on the surface of poor, depleted tropical soils to efficiently take up dissolved nutrients before they percolate down to mineral soil is shown.
A peak of litterfall occurred on all four sites during a May-June period of high rainfall before the driest time of the year and there was no consistent seasonal variation.
Decomposition and macroinvertebrate colonization of aquatic and terrestrial leaf material in alkaline and acid still water
The effects of low pH on the decomposition of both terrestrial and aquatic macrophyte litter appeared to be caused by interactive effects ofLow pH onThe microbial decomposition, on the detritivorous macroinvertebrate fauna and, in the case of N. alba, onThe resource quality of thedetritus.
Bromeliaceae: Profile of an Adaptive Radiation
This book, first published in 2000, presents a synthesis of the extensive information available on the biology of Bromeliacea, a largely neotropical family of about 2700 described species, concentrates on function and underlying mechanisms.
