  abstract = {{T}ank bromeliads form a conspicuous, yet neglected freshwater habitat in {N}eotropical forests. {R}ecent studies driven by interests in medical entomology, fundamental aspects of bromeliad ecology and experimental research on food webs have, however, prompted increasing interest in bromeliad aquatic ecosystems. {A}s yet, there is nothing in the literature about the life histories and environmental drivers of invertebrate population dynamics in tank bromeliads. {B}ased on fortnightly samples taken over oneyear, size frequency plots and individual dry masses allowed us to establish the life cycles and growth rates of the dominant aquatic invertebrates in a common bromeliad species of {F}rench {G}uiana. {L}inear mixed-effect models and {M}antel tests were used to predict changes in density, biomass, and growth rates in relation to temperature, rainfall, humidity and detrital resources. {A}nnual variations in invertebrate densities and biomasses could be described according to three types of distribution: unimodal, bimodal or almost constant. {D}espite seasonal variations, precipitation, temperature, relative humidity and detritus concentration accounted significantly for changes in density and biomass, but we found no significant responses in growth rates of most invertebrate species. {S}pecies rather displayed non-seasonal life cycles with overlapping cohorts throughout the year. {T}here was also a trend for delayed abundance peaks among congeneric species sharing similar functional traits, suggesting temporal partitioning of available resources. {B}eyond novel knowledge, quantitative information on life histories is important to predict food-web dynamics under the influence of external forcing and self-organisation. {O}ur results suggest that changes in species distribution that will affect population dynamics through biotic interactions in space and/or time could have greater effects on food webs and ecosystem functioning than changes in environmental factors per se.},
