Annotated Checklist

An annotated checklist of the free-living freshwater Copepoda recorded in different regions in Ecuador (including the Amazon, the Andes, the coastal region, and the Galapagos Islands) is here provided. We revised all published records, critically evaluated the validity of each taxon and provided short taxonomic and biogeographical remarks for each one. A total of 27 taxa have been reported, including species and records at the generic level only. The species and taxa identified only up to the generic level belong to five families and 14 genera. The Cyclopoida is the most diverse group with 16 records belonging to species (or identified to the generic level only) and eight genera, followed by the Harpacticoida with six species, one identification to the generic level only, and four genera, and Calanoida with four species belonging to two genera. A total of 18 taxa are recorded for the Andes. Six have been recorded in the Amazon, two are recorded for the coastal region, and six for the Galapagos. One species is shared between the Amazon and the Andes. One species is shared between the coastal region and the Amazon. Seventeen are only reported from the Andes and four are only reported from the Amazon. At the current status of the knowledge, any attempt to analyze and generalize distributional patterns of copepods in Ecuador is premature due to the scarcity of available information, and evidently there is an urgent need for more extensive field collections. A few working hypothesis for future studies are identified.

Annotated Checklist

Woodlice are key organisms for nutrient cycling in many terrestrial ecosystems; however, knowledge on this invertebrate group is limited as for other soil fauna taxa. Here, we present an annotated checklist of the woodlice of Belgium, a small but densely populated country in Western Europe. We reviewed all 142 publications on Belgian woodlice, the oldest dating back to 1831 and re-identified all doubtful specimens from the Royal Belgian Institute of Natural Sciences (RBINS) collection. These data is complemented with observations from extensive field surveys dating from March 2014 until December 2017. We report 36 species of woodlice with free-living populations for Belgium. Nine species can be added compared to the latest checklist published in 2000 being Hyloniscusriparius (C. Koch, 1838), Miktoniscuspatiencei Vandel, 1946, Trichoniscoidessarsi Patience, 1908, Haplophthalmusmontivagus Verhoeff, 1941, Porcelliomonticola Lereboullet, 1853, Metatrichoniscoidesleydigii (Weber, 1880), Trichoniscusalemannicus Verhoeff, 1917, Elumacaelata (Miers, 1877) and Philosciaaffinis Verhoeff, 1908. Two species are deleted from the checklist (Ligidiumgermanicum Verhoeff, 1901 and Armadillidiumdepressum Brandt, 1833) because records are doubtful and no material has been preserved. Additionally the data of the field surveys is used to determine a species status of occurrence in Belgium. For each species, a short overview of their first records is provided and their confirmation as part of the Belgian fauna, their current status, as well as a complete bibliography of the species in Belgium.

We present an updated checklist of the rotifer fauna from inland aquatic habitats in continental Ecuador and the Galápagos islands based on published rotifer records found in the literature. The checklist summarizes the status of the current taxonomic and faunistic knowledge on rotifers in Ecuador, updates the nomenclature, and reports the regions where each species has been found in the country. A total of 287 valid species (269 monogononts and 18 bdelloids was found. The Ecuadorian region with the highest number of records was Amazonia (228) followed by the Coastal region (139) and the Andes (121), whereas in the Galápagos Archipelago only 40 species have been recorded. Studies of the rotifer fauna of the areas are scarce and quite recent, pointing to important gaps in our knowledge on taxonomy and biogeography of Ecuadorian rotifers.

Annotated Checklist

Abstract An annotated checklist of the cestode parasites of Argentinean wild birds is presented, as the result of a compilation of parasitological papers published between 1900 and April 2021. This review provides data on hosts, geographical distribution, sites of infection, location of material deposited in helminthological collections, references and taxonomic comments. A host/parasite list is also provided. During this period, 38 papers were published that gather information about 34 cestode nominal species and 11 taxa identified at generic level, belonging to three orders, ten families and 35 genera. The highest number of cestode taxa was recorded in the family Hymenolepididae, with 12 nominal species and two taxa identified at generic level, followed by Dilepididae, with eight nominal species and three taxa identified at generic level. Of the 1042 species of birds reported in Argentina, only 29 (2.8%) were reported as hosts of adult cestodes. The families of birds with the highest number of reported taxa were Laridae and Anatidae, with 20 and 14 taxa, respectively.

Available Information

According to recent estimates the mycota of Sri Lanka is highly diverse, yet it has been relatively little studied and remains poorly understood. Sri Lanka may contain up to 25,000 species of fungi, of which only a little more than 2000 are presently known, and this estimate does not take into account the large number of exotics introduced along with food, plantation, and ornamental plants. Mycological research in Sri Lanka has been limited to certain parts of the country, and the available information is widely dispersed, difficult to access, and plagued by synonymy. Commercially cultivable mushrooms were first introduced to Sri Lanka in 1985, and today both endemic and non-native species are cultivated. This paper addresses the current status of Sri Lankan mushroom research, and suggests measures which are needed to support the future development of Sri Lankan mycology.

Abstract We conducted a taxonomical study of epiphytic diatoms on the macrophytes Polygonum hydropiperoides, Ludwigia peruviana and Alternanthera philoxeroides collected in the mesotrophic reservoir Piraquara II flooded in 2009, located in the state of Paraná. A total of 135 infrageneric taxa were identified, among them five at generic level and other five are first records to the state. We provided illustration, valve metrics, meristics limits and taxonomic reference for each taxon. Also, life forms and species frequency are given. The most frequent diatoms totalized 15.3% of total identified taxa and sporadic species represented 54.7%. Achnanthidium minutissimum (Kützing) Czarnecki and Brachysira neoexilis Lange-Bertalot occurred in more than 90% of analyzed samples. Among the very frequent diatoms we found other species included in Achnantidium, Fragilaria and Eunotia. The solitary Discotella stelligera (Cleve & Grunow) Houk & Klee and the short chain Aulacoseira tenella (Nygaard) Simonsen are free living species that entangle among diatoms from the biofilm.

Free Living Nematode

There is increasing interest in the use of the free-living nematode Caenorhabditis elegans as a tool for parasitic nematode research and there are now a number of compelling examples of its successful application. C. elegans has the potential to become a standard tool for molecular helminthology researchers, just as yeast is routinely used by molecular biologists to study vertebrate biology. However, in order to exploit C. elegans in a meaningful manner, we need a detailed understanding of the extent to which different aspects of C. elegans biology have been conserved with particular groups of parasitic nematodes. This review first considers the current state of knowledge regarding the conservation of genome organisation across the nematode phylum and then discusses some recent evolutionary development studies in free-living nematodes. The aim is to provide some important concepts that are relevant to the extrapolation of information from C. elegans to parasitic nematodes and also to the interpretation of experiments that use C. elegans as a surrogate expression system. In general, examples have been specifically chosen because they highlight the importance of careful experimentation and interpretation of data. Consequently, the focus is on the differences that have been found between nematode species rather than the similarities. Finally, there is a detailed discussion of the current status of C. elegans as a heterologous expression system to study parasite gene function and regulation using successful examples from the literature.

This paper presents the modeling of sand ridge deposits located in the coastal region of the Sepetiba bay, at the Itaguaí County, State of Rio de Janeiro, based on a geophysical survey using ground penetration radar (GPR) and electric sounding (VES). Until the present there is no detail regional mapping discussing the origin of these deposits. The purpose of the study is the subsurface geophysical characterization of the sedimentary deposits to be integrated with a geological model for the whole area. The SEV acquired in sand ridges showed high resistivity at the first geo-electrical layer that correlates to sand deposits. However, the VES acquired between sand ridges showed low resistivity on the same deep correlated to clayey deposits. The GPR data on the sand ridges, showed inclined reflectors indicated progradation of the sediments. Gradix IV and IPI2win were used for processing and interpretation of the data. Results showed coherence with the available information about the local geology, beyond a clear correlation with the hand auger soundings in the area.
