“…On the one hand this can be due to environmental factors that were not measured, such as water volume which was shown to affect invertebrate diversity and the archaeal and bacterial community composition and the pathway of methane formation in tank bromeliads (Dézerald et al 2014;Brandt et al 2014;Brandt 2015). On the other hand there is probably a large stochastic component connected with the ephemerality of the plants and dispersal dynamics (Farjalla et al 2012;Jocque and Field 2014).…”

Background and aims Tank bromeliads collect organic matter and rainwater (= tank slurry) between their densely arranged leaf axils for their nutrient demand. Diverse communities of microorganisms inhabit these tanks and are responsible for the breakdown of organic matter. Anaerobic degradation results in the release of substantial amounts of methane. We hypothesized that each individual bromeliad harbors its own microbial community, which is affected by chemical tank-slurry properties. We further hypothesized that methanotrophic bacteria inhabit bromeliad tank slurries, potentially able to oxidize the produced CH 4 . Methods We investigated communities of Bacteria, Archaea, methanogenic and methanotrophic microorganisms measuring their abundance (qPCR) and composition (TRFLP) within eight bromeliad tanks of the species Werauhia gladioliflora sampled in a Costa Rican lowland forest. Tank slurries were analyzed for pH, carbon, nitrogen, oxygen and fatty acid concentrations. Methane oxidation rates were determined in five bromeliad tank slurries.Results Our results showed that microbial communities differed between plants and were affected by chemical tank slurry properties. Further, not only methanogenic archaea but also methanotrophic bacteria were detected in the tanks of all bromeliad plants, the latter being potentially able to aerobically oxidize between 25 and 62 μg CH 4 gdw. Conclusion Our results indicate that every bromeliad tank is a unique island with respect to its resident microbial community. The presence of methanogens and active methanotrophs in all tank slurries further indicates the potential for both methane formation and methane oxidation.

“…In general, there is a positive relationship between invertebrate fauna (abundance and richness) and volume in phytotelmata (Schmidl et al 2008, Jabiol et al 2009, Campos 2013, Dézerald et al 2014. However, water volume has a higher influence on the abundance of invertebrates in environments with frequent droughts, mainly due to egg dehydration and larval mortality (Yanoviak 1999a, Paradise 2004).…”

We assessed the immature stages of Ceratopogonidae (Diptera) in artificial containers in an urban forest fragment in Manaus (Brazil), including their behavioral, biological and ecological information. In addition, we evaluated the effects of deforestation in an open and forested area on Ceratopogonidae communities. Immatures were sampled between August 2012 and July 2014 in artificial containers installed in both habitat types. We collected 685 immatures of seven morpho-species of Bezzia Kieffer, Culicoides Latreille, Dasyhelea Kieffer, Forcipomyia Meigen, and Palpomyia Meigen. In the open area, we recorded higher temperature and electrical conductivity values than in the forested area; however, these variables did not differ between seasons. Water volume was higher in open area and in rainy season, while pH was similar in both areas and seasons. Species richness was higher in forested area, but did not differ between seasons. We did not record differences in abundance between areas or seasons. Community composition differed between areas, but not between seasons. We provide the first records of Culicoides (Hoffmania) insignis Lutz and C. (Haematomyidium) quasiparaensis Clastrier in artificial containers from the state of Amazonas. Our results suggest that the preservation of forested areas in Amazonas is fundamental for the maintenance of the life cycle of some species of Ceratopogonidae.

KIFFER Jr., Compared to other aquatic ecosystems, the dynamics of biotic and abiotic factors in phytotelmata occur at short intervals, given that their permanence in the environment depends on the survival of host plants and rates of water collection and evaporation (Cogliatti-Carvalho et al, 2010;Dézerald et al, 2014). Therefore, small changes in the environmental conditions and characteristics of host plants may result in differences in the structure and composition of phytotelm communities (Ospina-Bautista et al, 2008;Dézerald et al, 2014;Cardoso et al, 2015). Armbruster et al (2002) observed strong correlations among plant morphology and the volume of stored water with the abundance of organisms in bromeliad tanks.…”

“…Furthermore, recent studies have found that food resources, i.e., algae and organic detritus, may vary in phytotelmata held by shaded and unshaded bromeliads (Yee and Willig, 2007;Brouard et al, 2012;Dézerald et al, 2014). According to Kaufman et al (2006), in unshaded bromeliads, algae constitute a high energetic resource to consumers because they provide nutritionally important compounds such as sterols, fatty acids and organic carbon.…”

Assessing the role of canopy cover on the colonization of phytotelmata by aquatic invertebrates: an experiment with the tank-bromeliad Aechmea lingulata

The presence of canopy cover may influence the amount of organic detritus and stored water in bromeliad tanks and, consequently, the colonization of these ecosystems by aquatic invertebrates. The aim of this study was to determine the effects of canopy cover on the colonization of the tank-bromeliad Aechmea lingulata in the restinga, an ecosystem composed of a variety of plant communities in the sandy coastal plains of Brazil. We hypothesized that the taxonomic composition of invertebrate communities would differ between bromeliads covered and not covered by a dense canopy (shaded and unshaded bromeliads). Prior to the beginning of the experiment, bromeliads of similar size were carefully washed to remove all organisms and organic detritus, and their tanks were filled with 1.0 L of spring water. On days 7, 14, 21, 30, 45, 60 and 90, four bromeliad tanks of each shade treatment were sampled to determine invertebrate communities, stored water and organic detritus. Average daily values of water temperature and light intensity were higher in unshaded than in shaded bromeliads. The amount of fine particulate organic matter (FPOM) and stored water did not differ between treatments, but the amount of coarse particulate organic matter (CPOM) was higher in shaded bromeliads. Ostracoda, Hydracarina and Oligochaeta were the most abundant taxa in bromeliad tanks. Among insects, Culicidae, Chironomidae and Ceratopogonidae were the most representative. Invertebrate colonization occurred quickly and values of abundance were higher in unshaded bromeliads compared to shaded bromeliads. The values for biomass and richness did not differ between treatments or colonization times, and the taxonomic composition of invertebrate communities was similar throughout the experiment. Our results showed that canopy cover had a small influence on the colonization of tanks of A. lingulata in restinga, not corroborating the proposed hypothesis. These findings were likely due to the lack of variation in environmental conditions that are relevant to the colonization process, such as stored water and FPOM. However, because the amounts of CPOM were higher in shaded bromeliads, the taxonomic composition of invertebrate communities could have differed if typical shredders were present.
