  abstract = {1. {F}unctional traits are commonly used in predictive models that link environmental drivers and community structure to ecosystem functioning. {A} prerequisite is to identify robust sets of continuous axes of trait variation, and to understand the ecological and evolutionary constraints that result in the functional trait space occupied by interacting species. {D}espite their diversity and role in ecosystem functioning, little is known of the constraints on the functional trait space of invertebrate biotas of entire biogeographic regions. 2. {W}e examined the ecological strategies and constraints underlying the realized trait space of aquatic invertebrates, using data on 12 functional traits of 852 taxa collected in tank bromeliads from {M}exico to {A}rgentina. {P}rincipal {C}omponent {A}nalysis was used to reduce trait dimensionality to significant axes of trait variation, and the proportion of potential trait space that is actually occupied by all taxa was compared to null model expectations. {P}ermutational {A}nalyses of {V}ariance were used to test whether trait combinations were clade-dependent. 3. {T}he major axes of trait variation represented life-history strategies optimizing resource use and antipredator adaptations. {T}here was evidence for trophic, habitat, defence and life-history niche axes. {B}romeliad invertebrates only occupied 16%-23% of the potential space within these dimensions, due to greater concentrations than predicted under uniform or normal distributions. {T}hus, despite high taxonomic diversity, invertebrates only utilized a small number of successful ecological strategies. 4. {E}mpty areas in trait space represented gaps between major phyla that arose from biological innovations, and trait combinations that are unviable in the bromeliad ecosystem. {O}nly a few phylogenetically distant genera were neighbouring in trait space. {T}rait combinations aggregated taxa by family and then by order, suggesting that niche conservatism was a widespread mechanism in the diversification of ecological strategies.},
