“…Most plants are adapted to deal with the water deficit stress, but high light incidence imposes strong constraints into plant survival and development (Scarano et al, 2001). Our experimental site can be characterized as having patches of trees and shrubs that are surrounded by open sandy areas, wherein terrestrial tank-bromeliads are particularly abundant (up to 6,360 bromeliads ha -1 in some regions) (Rocha-Pessôa et al, 2008).…”

The primary goal of this study was to evaluate the relative importance of habitat physical properties, bottom-up and top-down factors, and their interaction on algae biomass in tank-bromeliads. We sampled algae biomass (chlorophyll-a concentration), micro-metazoan density, mosquito abundance, and several environmental variables, including nutrient concentrations and characteristics of the habitat physical structure, in a survey of 64 tank-bromeliads of four different species (Aechmea nudicaulis, Aechmea lingulata, Neoregelia cruenta, and Vriesea neoglutinosa). We analyzed the complete and individual bromeliad species datasets using an information-theoretic model selection approach (Akaike's information criterion). Bromeliad species, maximum water volume, and bromeliad diameter comprised the best model for determining chlorophyll-a concentrations for the complete dataset. The maximum water volume also comprised the best model to explain chlorophyll-a concentrations in three of four bromeliad species datasets. Interactions between consumers and nutrient concentration were included in the subsequent models, but they were not statistically significant. Taken together, these results demonstrate that the impact of habitat size on the associated autotrophic biomass occurs possibly via changes in community susceptibility to disturbances, particularly drought. We can conclude that habitat size is more important than resource availability or herbivory on phytotelm autotrophic biomass regulation in these natural microcosms.

“…Depending on its location, each bromeliad receives different amounts of litter and sunlight energy, which affects the metabolism of its entire water column (Guimarães-Souza et al, 2006). Tank bromeliads are usually present at high abundances in mature tropical rainforests and tropical coastal shrub vegetation, reaching 6,360 bromeliads ha -1 in the latter (Cascante-Marin et al, 2006, Rocha-Pessoa et al, 2008. These high natural abundances of discrete aquatic habitats create a large number of replicates at the ecosystem level in a limited area, leading some to suggest that tank bromeliads can act as model ecosystems for aquatic ecology (Srivastava et al, 2004).…”

Evaluating the factors that regulate bacterial growth in natural ecosystems is a major goal of modern microbial ecology. Phytotelm bromeliads have been used as model ecosystems in aquatic ecology as they provide many independent replicates in a small area and often encompass a wide range of limnological conditions. However, as far as we know, there has been no attempt to evaluate the main regulatory factors of bacterial growth in these aquatic ecosystems. Here, we used field surveys to evaluate the main bottom-up factors that regulate bacterial growth in the accumulated water of tank bromeliads. Bacterial production, water temperature, water color, chlorophyll-a, and nutrient concentrations were determined for 147 different tank bromeliads in two different samplings. Bromeliad position and the season of sampling were also noted. Bacterial production was explained by ion ammonium concentration and water temperature, but the total variance explained was low (r 2 = 0.104). Sampling period and bromeliad position were included in additional models that gave empirical support for predicting bacterial production. Bromeliad water tanks are extremely variable aquatic ecosystems in space (among bromeliads) and time (environmental conditions can change within hours), and it is well known that bacterial production responds rapidly to environmental change. Therefore, we concluded that several factors could independently regulate bacterial growth in phytotelm bromeliads depending on the characteristics of each bromeliad, such as location, amount of detritus, and ambient nutrient concentrations. A clear bottom-up limitation pattern of bacterial production in tropical phytotelm bromeliads was not found.

“…The high survival rate of Bromelia antiacantha may be related to its rusticity and plasticity. Rocha-Pessoa et al (2008), during their study in the restinga of Arraial do Cabo, Rio de Janeiro, found a high frequency of this species in a closed wrack zone, which can indicate tolerance to high salinities, characteristic of this vegetation zone. It is worth mentioning that the individuals found alive were in the quadrant "3", i.e., in a shaded area and a closed forest.…”

The state of Rio de Janeiro has been degraded mainly in lowlands, where protected areas harboring most remaining forests are located. The present study aimed to assess the application of compensatory measures (CM) to restore the vegetation of the Bosque da Barra Municipal Natural Park. We analyzed the survival of planted specimens by dividing the area into six quadrants with approximately nove hectares each. For the analysis, we used a frequency class method and assessed the success rate per quadrant, where 2,125 seedlings of 73 native restinga species were planted. We found 1,245 seedlings, which corresponded to 59% of the planting. Among those seedlings, 885 were alive, which represented a survival rate of 42%. The average survival per species was 26%. Forty-seven species survived out of 73 planted species. All in all, environmental compensation is an important public policy tool, and this legal device should be used to ensure the restoration of environmental damages, aiming to maintain what establishes the 225th article of the Federal Constitution for present and future generations.
