RESUMO

This is the first study of mineral content and basic physicochemical parameters of honeys of Montenegro. We examined honey samples from eight different micro-regions of Montenegro, and the results confirm that, with the exception of cadmium in samples from two regions exposed to industrial pollution, none of the 12 elements analyzed exceeded the maximum allowable level. The samples from areas exposed to industrial pollution were clearly distinguished from samples from other regions of Montenegro in the detectable contents of Pb, Cd, and Sr. This study showed that chemometric techniques might enhance the classification of Montenegrin honeys according to their micro-regional origin using the mineral content. Linear discriminant analysis revealed that the classification rate was 79.2% using the cross-validation method.

RESUMO

This paper provides a current overview of the diversity of the marine water mite family Pontarachnidae of the Mediterranean Sea. The checklist includes ten species from two genera, i.e. Litarachna Walter, 1925 and Pontarachna Philippi, 1840. Two species i.e., Litarachna muratsezgini sp. nov. and Pontarachna turcica sp. nov. from the Gulf of Antalya (Levantine Sea, Turkey), are described as new for science. Moreover, the key for the identification of Mediterranean Pontarachnidae species and a brief discussion on the current gaps and future prospects of our knowledge of this important but neglected component of the marine meiofauna are given.

RESUMO

A worldwide checklist of the pontarachnid mites is provided based on published reports and original data. A total of 53 valid species of pontarachnid mites have been compiled, of which the genus Pontarachna includes 30 species, while 23 species belong to the genus Litarachna. The highest number of species (n=16) is reported from the marine province Tropical West of the Pacific Ocean. A deutonymph of Litarachna triangularis is reported here from Dongsha Atoll, Taiwan. Patterns of endemism and seemingly incomplete species distributional records are the result of a lack of intensive faunistic surveys in different parts of the world. The taxonomy of Pontarachnid mites will be improved by the use of mite-specific sampling methods and the application of molecular phylogenetics.

RESUMO

Effective identification of species using short DNA fragments (DNA barcoding and DNA metabarcoding) requires reliable sequence reference libraries of known taxa. Both taxonomically comprehensive coverage and content quality are important for sufficient accuracy. For aquatic ecosystems in Europe, reliable barcode reference libraries are particularly important if molecular identification tools are to be implemented in biomonitoring and reports in the context of the EU Water Framework Directive (WFD) and the Marine Strategy Framework Directive (MSFD). We analysed gaps in the two most important reference databases, Barcode of Life Data Systems (BOLD) and NCBI GenBank, with a focus on the taxa most frequently used in WFD and MSFD. Our analyses show that coverage varies strongly among taxonomic groups, and among geographic regions. In general, groups that were actively targeted in barcode projects (e.g. fish, true bugs, caddisflies and vascular plants) are well represented in the barcode libraries, while others have fewer records (e.g. marine molluscs, ascidians, and freshwater diatoms). We also found that species monitored in several countries often are represented by barcodes in reference libraries, while species monitored in a single country frequently lack sequence records. A large proportion of species (up to 50%) in several taxonomic groups are only represented by private data in BOLD. Our results have implications for the future strategy to fill existing gaps in barcode libraries, especially if DNA metabarcoding is to be used in the monitoring of European aquatic biota under the WFD and MSFD. For example, missing species relevant to monitoring in multiple countries should be prioritized for future collaborative programs. We also discuss why a strategy for quality control and quality assurance of barcode reference libraries is needed and recommend future steps to ensure full utilisation of metabarcoding in aquatic biomonitoring.

RESUMO

Springs are often recognized as biodiversity hotspots on the regional scale but at the same time they are among the most endangered freshwater habitats. Water mites are among the aquatic animal groups with highest share of crenobiotic (= spring-dwelling) species and, therefore, are possibly the best indicators of the ecological status of spring habitats. We studied water mites and environmental factors correlated with their distribution pattern along a eucrenon-hypocrenon gradient. The sampling was conducted in 14 karstic springs located in the Mediterranean part of Montenegro. We collected 17 water mite species of which four species were crenobiotic. We did not find significant differences between the water mite assemblages from the source and springbrook. Similarly, there were no significant differences in number of species and abundance between the studied spring sections, neither for crenobiotic taxa nor for non-crenobiotic taxa. We found that the number of non-crenobiotic taxa was predicted mainly by water depth, whereas the abundance of crenobionts was most strongly associated with temperature. No significant predictors for the number of crenobiotic species in spring habitats were found. Our results revealed also that distance from the nearby water body was the main driver of the crenobiotic species abundance in eucrenon suggesting the large effects of the local flooding events on crenobiotic species. Water mites may help in assessing the response of crenobiotic assemblages in those spring habitats which likely to be flooded in future as the results of ongoing climatic changes.

RESUMO

This paper examines the impact of disturbance factors-flooding and intermittency-on the distribution of water mites in the riparian springs situated in the valley of a small lowland river, the Krapiel. The landscape factors and physicochemical parameters of the water were analysed in order to gain an understanding of the pattern of water mite assemblages in the riparian springs. Three limnological types of springs were examined (helocrenes, limnocrenes and rheocrenes) along the whole course of the river and a total of 35 water mite species were found. Our study shows that flooding influences spring assemblages, causing a decrease in crenobiontic water mites in flooded springs. The impact of intermittency resulted in a high percentage of species typical of temporary water bodies. Surprisingly, the study revealed the positive impact of the anthropogenic transformation of the river valley: preventing the riparian springs from flooding enhances the diversity of crenobiontic species in non-flooded springs. In the conclusion, our study revealed that further conservation strategies for the protection of the riparian springs along large rivers would take into account ongoing climatic changes and possible the positive impact of the anthropogenic transformation of river valleys.

RESUMO

Intermittent rivers and ephemeral streams (IRES) are common across Europe and dominate some Mediterranean river networks. In all climate zones, IRES support high biodiversity and provide ecosystem services. As dynamic ecosystems that transition between flowing, pool, and dry states, IRES are typically poorly represented in biomonitoring programmes implemented to characterize EU Water Framework Directive ecological status. We report the results of a survey completed by representatives from 20 European countries to identify current challenges to IRES status assessment, examples of best practice, and priorities for future research. We identify five major barriers to effective ecological status classification in IRES: 1. the exclusion of IRES from Water Framework Directive biomonitoring based on their small catchment size; 2. the lack of river typologies that distinguish between contrasting IRES; 3. difficulties in defining the 'reference conditions' that represent unimpacted dynamic ecosystems; 4. classification of IRES ecological status based on lotic communities sampled using methods developed for perennial rivers; and 5. a reliance on taxonomic characterization of local communities. Despite these challenges, we recognize examples of innovative practice that can inform modification of current biomonitoring activity to promote effective IRES status classification. Priorities for future research include reconceptualization of the reference condition approach to accommodate spatiotemporal fluctuations in community composition, and modification of indices of ecosystem health to recognize both taxon-specific sensitivities to intermittence and dispersal abilities, within a landscape context.

RESUMO

The water mite genus Protolimnesia Lundblad, 1927 is distributed in South and Central America, the Caribbean (Haiti) and southern parts of the USA (Goldschmidt 2004). One odd record is known from Oman (Smit & Pesic 2010). In addition to the nominate subgenus, the genus also includes Protolimnesella Cook, 1980 and Voldroguella Cook, 1981, typical inhabitants of interstitial habitats (Goldschmidt 2004). The nominate subgenus includes seven species and subspecies, most of them are stream-dwellers, but Protolimnesia longa Besch, 1963 appears to be a characteristic inhabitant of the interstitial of intermittent streams. This species was described by Besch (1963) based on a single male from the interstitial of a dry stream at 1200 m altitude in Argentina. Since then, no further records of this species were published. In the original description Besch (1963) illustrated only the ventral and dorsal side. Smit (2002) and Goldschmidt (2004) re-examined the holotype of P. longa deposited in the Viets Collection (SMF) and provided illustrations of the palp and ejaculatory complex, respectively. However, some important characteristics are neither given in the original description nor are visible in the type material. Smit (2002) mentioned that both fourth legs in the holotype slide are positioned in such a way that examination of the claws of IV-L-6 is not possible, Goldschmidt (2004) stated that the ejaculatory complex in the type is mounted laterally and most probably squashed.

RESUMO

The rosette architecture of some bromeliad species traps water and organic matter from the canopy in leaf axils (forming phytotelmata) and harbors many species of invertebrate animals (Frank & Lounibos 2009). Some water mites are adapted to live in phytotelmata; typically recorded from water-filled tree holes, bromeliad tanks, and a range of plant axils. Karl Viets (1939) was the first acarologist who discovered Micruracaropsis phytotelmaticola (Viets, 1939) in the water contained in the leaf bases of epiphytic Bromeliaceae in Surinam. Later on, Orghidan et al. (1977) described Arrenurus bromeliacearum Orghidan, Gruia & Viña Bayés, 1977 from phytotelmata in Cuba. Orghidan & Gruia (1987) reported Arrenurus andrewfieldi Orghidan & Gruia, 1983 from phytotelmata of epiphytic bromeliad Vriesea platynema in Venezuela. Smith & Harvey (1989) described Arrenurus kitchingi Smith & Harvey, 1989 from water-filled tree holes in Queensland, Australia. The same authors (Smith & Harvey 1989) also reported that members of genus Thyopsis occur in water-filled tree holes in Ohio, USA. Rosso de Ferradás & Fernández (2001) reported two Arrenurus species from water accumulated in Guzmania mucronata (Bromeliaceae) in Venezuela, A. andrewfieldi Orghidan & Gruia, 1983 and A. caquetiorum Rosso de Ferradás & Fernández, 2001.

RESUMO

Adults of Bromeliacaruscardoso gen. n., sp. n. are described from phytotelmata of Quesneliaarvensis (Vellozo) Mez. (Bromeliaceae) in the subtropical area of the Atlantic rainforest, São Paulo State, Brazil. The new genus Bromeliacarus is proposed and diagnosed, based primarily on the autapomorphic presence of 7-9 pairs of acetabula flanking the gonopore. A possible relationship between Bromeliacarus and other Wettinidae are discussed.

RESUMO

A new water mite species, Hygrobates zawali n. sp., is described from material collected in the ancient Lake Ohrid on the Balkan Peninsula. This species has been confused for a long time with the rhithrobiontic H. diversiporus Sokolow, 1927, known from the Caucasus (Russia) and Turkey. The new species closely resembles H. quanaticola Schwoerbel & Sepasgozarian, 1976, a little documented species described from Iran, which is here illustrated based on re-examination of the type material. Furthermore, a key for the identification of species of the subgenus Rivobates Thor, 1897, from the Western Palaearctic is given.

RESUMO

NEW RECORDS OF PONTARACHNID MITES (ACARI: Hydrachnidia) from the Caribbean island of Puerto Rico are presented. Litarachna lopezae sp. n., from substrata collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, is described as new to science. The new species was collected from nearly 70 m depth, the greatest depth from which pontarachnid mites have been found until now. In addition, a Litarachna sp. was also found in association with the tube of the polychaete Sabellastarte magnifica (Shaw, 1800) at the shallow waters of north Puerto Rico.
