Phytotelmata, small aquatic ecosystems within different structures of terrestrial plants, occur in the inflorescescences and infructescences of Xanthosoma (Araceae). This study reports changes in composition and abundance of arthropods during the anthesis of inflorescences and in the developing infructescences of three species of Xanthosoma at three different geographic locations: (1) X. undipes in a tropical cloud forest of Costa Rica, Central America; (2) X. daguense in a tropical cloud… 
Floral biology of Schismatoglottis baangongensis (Araceae) in West Sarawak, Borneo
Low pollen/ovule ratio of S. baangongensis indicated an efficient pollination mechanism and Ester compound class floral odours, especially the dominant compounds 3-butenoic acid, 3-methyl-, methyl ester, were decisive in attracting pollinators.
Interaction and Distribution of Beetles (Insecta: Coleoptera) Associated with Heliconia bihai (Heliconiaceae) Inflorescences
The objective of this study was to determine the distribution of beetles in Heliconia bihai (L.) (Zingiberales: Heliconiaceae) bracts in cultivated and uncultivated areas in northeastern Brazil and to describe their functional relationships.
Patterns of diversity of flower-visitor assemblages to the understory Araceae in a tropical mountain forest in Colombia
Local strategies for the conservation of the diversity of insect flower-visitors and their interactions should be focused on the implementation of agricultural practices that reduce the use of pesticides within adjacent commercial plantations and the avoidance of illegal clearings, maintaining unbroken elevational gradients of forest, which is the only way to protect the flowering resources for anthophilous insects.
Infructescence size has a larger effect than light environment on the abundance of different arthropod feeding guilds dwelling on the infructescences of a terrestrial bromeliad in a xerophytic forest
Bromelia serra is an understory bromeliad living in xerophytic forests of the Humid Chaco, which shows high phenotypic plasticity when exposed to different environmental conditions.
Floral Associations of Cyclocephaline Scarab Beetles
The most important areas for future research include elucidating the factors that attract cyclocephalines to flowers including floral scent chemistry and thermogenesis, determining whether cyclocephaline dicot visitation is truly limited to the New World, and inferring evolutionary relationships within the Cyclocephalini to rigorously test vicarance hypotheses, host plant shifts, and mutualisms with angiosperms.
Vertical and Horizontal Trophic Networks in the Aroid-Infesting Insect Community of Los Tuxtlas Biosphere Reserve, Mexico
The findings suggest that intrinsic plant factors could influence their occupation, and that the coexistence of distinct insect species in the assemblage could exert a direct or indirect influence on their ability to colonize such resources.
Visitor or vector? The extent of rove beetle (Coleoptera: Staphylinidae) pollination and floral interactions
The role of Staphylinidae as pollinators, and Coleoptera as a whole, is underestimated, and caution must be given to inferring the role of staphyl inids in pollination because rove beetles commonly function as inadvertent secondary pollinators or antagonists there to fulfil other ecological roles.
Local to Continental-Scale Variation in the Richness and Composition of an Aquatic Food Web
The surprising result that these communities are more variable within their host-plant populations than across North America suggests that the food web in S.purpurea leaves consists of two groups of species: a core group of mostly obligate pitcher-plant residents that have evolved strong requirements for the host plant and a larger set of relatively uncommon, generalist taxa that co-occur patchily.
Restoration of Plant–Pollinator Interactions: Pollination Neighborhood and Asymmetric Pollen Flow Between Restored Habitats in a Beetle‐Pollinated Aroid
Results show that the selection of different restoration strategies can alter two major components of plant–pollinator interactions in plants colonizing restored habitats, pollination neighborhoods, and pollen flow within the population.


Beetle pollination and fruit predation of Xanthosoma daguense (Araceae) in an Andean cloud forest in Colombia
This interaction with a fruit predator that is also a potential pollinator resembles brood-site pollination systems in which pollinators prey on part of the fruit set (e.g. Ficus, senita cacti, Yucca), making this system substantially more complex than previously described dynastine-pollinated systems in aroids.
The Aquatic Macrofauna of Water-Filled Bamboo (Poaceae: Bambusoideae: Guadua) Internodes in a Peruvian Lowland Tropical Forest
In the lowland tropical forest at Pakitza, Peru, bamboo (Guadua weberbaueri Pilger) internodes with lateral perforations contain a diverse aquatic fauna. We found a community of 29 species dominated
Beetle pollination of Dieffenbachia longispatha (Araceae)
Experiments demonstrate that the species is self-compatible and that fruit production is pol- experiences, suggesting that floral odors play a role as an attractant in the relationship with beetle pollinators.
Equal and Opposite Effects of Floral Offer and Spatial Distribution on Fruit Production and Predispersal Seed Predation in Xanthosoma daguense (Araceae) 1
The study suggests that the interaction of two ecological processes, pollination and predispersal seed predation, may cancel each other's effects under natural conditions.
Clumps of Heliconia Inflorescences as Ecological Islands
It is postulated that beta diversity is more important in increasing species richness of animals in Heliconia clumps than is alpha diversity (the diversity due to the number of species using a given resource).

It is hypothesized that Heliconia floral morphology, in which flowers are protected in water-filled, cuplike bracts, evolved as a defense against flower-feeding and seed-eating insects, and that local accumulations of insect species inHeliconia inflorescences follow a power function similar to that which is used to describe the accumulation of species on islands.
Succession and Stratification of Aquatic Insects Inhabiting the Leaves of the Insectivorous Pitcher Plant, Sarracenia purpurea
Greenhouse experiments and field collections were used in investigating the ecological relationships of three species of Diptera, Blaesoxipha fletcherl (Aldrich) (Sarcophagidae), Wyeomyla smlthll
The origin of bract liquid in a neotropical Heliconia species
The origin of the deep pools of liquid held in the cuplike bracts of Heliconia imbricata (Heliconiaceae), in which flower bases and fruits are submerged, was examined. Strong evidence was obtained
Effects of pH and resources on a processing chain interaction in simulated treeholes
The conclusion that this interaction is pH dependent gives support to the concept that abiotic factors play a role in determining the outcome of biotic interactions, and that acidification can have complex effects on communities.
Environmental biology: Heat reward for insect pollinators
In neotropical forests, adults of many large scarab beetle species spend most of their time inside the floral chambers of heat-producing flowers, where they feed and mate throughout the night and
