Abstract. 1. Relative to Nepenthes species in West Malaysia near the evolutionary centre of the genus, outlying species of Nepenthes in the Seychelles, Sri Lanka and Madagascar have fewer species of both prey and predator living in them, fewer and smaller guilds of species, much apparently empty niche space, less complex food webs, and a greater connectance. The ratios of prey to predators, and of connectance (C1) to the total number of trophic types present remain approximately constant. 
The metazoan food webs from six Bornean Nepenthes species
Predictions that webs will be more complex, and the food chains they contain will be longer, the closer they are to the centre of Nepenthes species diversity, are supported.
A re-examination of geographical variation in Nepenthes food webs
It is suggested that the structure of Nepenthes webs is influenced by four major factors: geographical, deterministic, stochastic and host pitcher, but that the relative importance of cach factor is highly variable and cannot be quantified at present.
Observations of the natural history and ecology of Nepenthes campanulata
This study conducted the first field-based survey of pitcher dimensions and the prey and invertebrate fauna in N. campanulata pitchers, sampled from plants growing on the cliff face above Deer Cave in Gunung Mulu National Park.
Why are Aedes mosquitoes rare colonisers of Nepenthes pitcher plants?

Aquatic arthropod communities in Nepenthes pitchers: the role of niche differentiation, aggregation, predation and competition in community organization
The structure and organization of aquatic arthropod communities in Nepenthes ampullaria pitchers were studied at two sites in Malaysia, finding that species belonging to the same trophic group commonly shared the same pitcher, because of high occurrence probabilities of dominant species and positive associations between some taxa.
Nepenthacarus, a new genus of Histiostomatidae (Acari: Astigmata) inhabiting the pitchers of Nepenthes mirabilis (Lour.) Druce in Far North Queensland, Australia
A new genus and species, Nepenthacarus warreni, is described from adults, deutonymphs, protonymphs and larvae collected from the fluid-filled pitchers of Nepenthes mirabilis (Lour.) Druce in northern
Variance in composition of inquiline communities in leaves of Sarracenia purpurea L. on multiple spatial scales
It is suggested that independent factors determining the abundances of individual species are important in determining community patterns in pitcher-plant inquilines and bacterial communities were found to vary significantly in composition among individual plants but not among populations or subpopulations.
Immature Diptera (excluding Culicidae) inhabiting phytotelmata in the Auckland and Wellington regions
Diptera larvae were relatively abundant in the leaf axils of the native epiphyte Collospermum hastatum, and in the fallen leaves of thenative nikau palm Rhypalostylis sapida.
Morphological correlates of necromass accumulation in the traps of an Eastern tropical pitcher plant, NepeJthes ampullaria Jack, and observations on the pitcher infauna and its reconstitution
The trap morphology, necromass accumulation rates and pitcher infauna of an eastern tropical pitcher plant, Nepenthes ampullaria, that grew in Madagascar are studied.
Functional morphology as an aid in determining trophic behaviour
This work has shown that the functional morphology of mouth-parts of astigmatic species inhabiting water-filled tree holes in the eastern USA and in Queensland, Australia, reveal a diversity of trophic groups, which allows for the more exact placement of acarine inhabitants in food webs of water- filled tree holes.


Environmental Control of Food Web Structure
The structure of 40 real food webs, representing aquatic and terrestrial communities from all latitudes, is found to be markedly affected by the degree of variability of the physical environment. In
The Role of Habitat Complexity and Heterogeneity in Structuring Tropical Mammal Communities
There was little association between habitat structure and the richness, diversity, abundance, and biomass of small mammals, and new species were added to complex communities primarily through guild expansion rather than guild addition.
Avian Community Organization and Habitat Structure
These results do not coincide with previous attempts at ecological generalization, and great care should be made of meticulously delineated subcommunities, resource measurement, and reproductive success, as well as events in the nonbreeding season.
The Mosquitos (Diptera: Culicidae) of the Seychelles.
One species and one subspecies new to science are here described for the first time and some notes are given regarding the taxonomy, bionomics and local distribution of the species concerned and the zoogeography of the groups to which they belong.

Objective methods, such as Vandermeer's (1972) grain matrix, should prove particularly useful in determining the numbers of trophic resources at different levels in natural communities without further delay.
The connectance of real ecosystems
In the work of Gardner and Ash by1, and May2 it has been shown that ecosystem stability (in the sense of Liapunov stability of equilibria3) imposes nontrivial constraints (summarised below) on
Community food webs have scale-invariant structure
In biological communities, the proportions of top, intermediate and basal species are, on average, independent of the total number of species, so there is a direct proportionality between the numbers of prey and predators.

Several years ago the Director of the Bernice P. Bishop Museum, Honolulu, was kind enough to lend me the Sapotaceous material from the Pacific region preserved in its Herbarium. It has been

It is shown that within habitats of a certain limited physical and temporal heterogeneity, the overlaps among niches, along their trophic dimensions, can be represented in a one-dimensional niche space far more often than would be expected by chance alone and perhaps always.
