“…While the Hydryphantidae from the Palearctic zone were represented with 27 species, the other families (Eylaidae: 2, Hydrachnidae: 1, Hydrodromidae: 1, Limnesiidae: 1) had less representation [3] [11]. Table 1 reveals that high amounts of carbon were measured in Hydrachna globosa (51.690%) while the nitrogen levels were high for Hydrachna skorikowi (13.060%), hydrogen was high in Hydrachna processifera (6.938%) and sulfur amounts were high in Eylais extendens (1.333%) whereas the least amount of carbon was found in Hydrachna skorikowi (47.050%), nitrogen in Georgella helvetica (8.647%), hydrogen amounts in Eylais extendens (6.112%) and sulfur in Hydrachna processifera (0.787%).…”

“…However, many of the structural characteristics found in the other supra genus (Hydryphantoidae, Lebetoidae, Hygrobatoidae) are not evident. Therefore, the problems in the systematics of the superfamily continue to date and the differentiation which started in the early Mesozoic age continues [3] [12]. There is wide acceptance in favor of the argument that during different geological ages the Hydracnidia which were essentially polyphyletic transposed from a terrestrial life into aquatic environments and that the initial settlement areas were primarily springs and later extended to other aquatic environments and that this proliferation and differentiation continues [13].…”

Abstract10 different species of water mites which are Georgella helvetica, Eylais extendens, Hydrachna globose, Hydrachna prosifera, Hydrachna skorikowi, Hydrodroma despiciens, Hydryphantes dispar, Limnesia fulgida, Eylais setosa, Hydryphantes flexuosus were used in this study. The total masses of these species were measured as mg with the use of an elemental analyzer to calculate the percentage of the organic components of their structures. The achieved values were assessed separately for each species and element with the interpolation method. Out of these organic elements, the amount of C with an approximately value of 50% was the highest for all species while the amounts of S which was approximately 1% was determined as the lowest for almost all species. The observed values were discussed in terms of the systematic of water mites.

“…The abundances of Ostracoda and Hydracarina in the tanks of A. lingulata are likely related to the high resistance of these organisms to stressful environmental conditions, including desiccation (Smith et al, 2001;Di Sabatino et al, 2008;Rossi et al, 2011). The ability of some aquatic invertebrates to produce dormant eggs is an adaptation that favors success in bromeliad tanks (Williams, 1997(Williams, , 2005.…”

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.

“…There has been much recent progress made by only a handful of taxonomists in the knowledge of Torrenticolidae from Palaearctic (e.g., Di Sabatino and Cicolani 1990;Di Sabatino et al 2003Pešić et al 2011Pešić et al , 2013Tuzovskij 2003Tuzovskij , 2012Tuzovskij , 2013, Afrotropical (Goldschmidt andSmit 2009, Pešić andSmit 2014a), Oriental (e.g., Pešić and Smit 2011Pešić and Smit 2014b;Pešić and Gerecke 2014), and Neotropical regions (Goldschmidt 2007). The present work represents the first in a series of descriptions intended to fill the gap in knowledge of Nearctic species.…”
