Nitrogen fluxes from treefrogs to tank epiphytic bromeliads: an isotopic and physiological approach
It is demonstrated for the first time that vertebrates contribute to bromeliad nutrition, and that this benefit is seasonally restricted.
Spider-fed bromeliads: seasonal and interspecific variation in plant performance.
Bromeliads absorbed more nitrogen coming from spider faeces than from flies, reinforcing the beneficial role played by predators in these digestive mutualisms.
Constraints on the functional trait space of aquatic invertebrates in bromeliads
The ecological strategies and constraints underlying the realized trait space of aquatic invertebrates were examined, using data on 12 functional traits of 852 taxa collected in tank bromeliads from Mexico to Argentina to understand the ecological and evolutionary constraints that result in the functional trait space occupied by interacting species.
The contribution of weak CAM to the photosynthetic metabolic activities of a bromeliad species under water deficit.

Bromeliad subfamilies showed a trade-off between two strategies: Tillandsioideae stored nitrogen into amino acids possibly for transamination reactions during nutritional stress and did not grow, whereas Bromelioidae used nitrogen for soluble protein production for immediate utilization, possibly for fast growth, highlighting that Bromeliaceae evolution may be directly associated with the ability to stock nutrients.

The authors' findings indicate that the low net CO2 exchange and the energy imbalance possibly increased the cyclic transport of electrons and activated the thermal dissipation of energy to avoid damage to the photosynthetic apparatus.
Species-Specific Effects of Ant Inhabitants on Bromeliad Nutrition
It is shown, for the first time, that predatory ants can translocate nutrients from one habitat to another within forests, accumulating nutrients in their feeding sites that become available to bromeliads.
A new species of Xystonotus Wolcott, 1900 (Acari, Hydrachnidia, Mideopsidae) from bromeliad phytotelmata in Brazilian Atlantic rainforest.

The rosette architecture of some bromeliad species traps water and organic matter from the canopy in leaf axils (forming phytotelmata) and harbors many species of invertebrate animals (Frank &…

The results highlight the importance of mineralizing bacteria on phyllosphere as a mechanism of N uptake by bromeliads.

Ants changed the composition and reduced the overall density of aquatic and terrestrial metazoans in bromeliad ecosystems, and effects of ants on species diversity were contingent on site, which demonstrates that the same predator can simultaneously initiate cascades in multiple ecosystems.
