The paper summarizes current knowledge upon taxonomy and distribution of the freshwater Gammarus Fabricius, 1775 in Iran. Based on the literature data, 24 species were recorded so far from the fresh waters in the country. Revision of previously published materials including type collections, and analysis of new materials, revealed presence of 18 valid freshwater Gammarus species in Iran (G. anodon, G. bakhteyaricus, G. baloutchi, G. crinicaudatus, G. hegmatanensis, G. komareki, G. lacustris, G. lobifer, G. loeffleri, G. lordeganensis, G. paricrenatus, G. parthicus, G. pretzmanni, G. pseudosyriacus, G. sepidannus, G. shirazinus, G. sirvannus and G. zagrosensis). Among the remaining six species, three (G. arduus, G. laticoxalis, G. syriacus) were reported as a result of misidentification and further three (G. miae, G. plumipes, G. projectus) appeared to be junior synonyms of other already described species. Distribution ranges of most of the species are restricted usually to only few localities in the mountainous terrain, so they may be treated as Iranian endemics. The only exceptions are: G. lacustris (widely distributed in Holarctic, with only few populations in Iran), G. komareki (widely distributed in the Balkan Peninsula and Asia Minor, in Iran recorded from the entire Alborz region) and G. pseudosyriacus (widely distributed in Asia Minor, in Iran found in the entire Zagros region). A brief remark on taxonomy of each species is presented, with emphasis on misidentifications, synonymies and similar species, supplemented by distribution data, and ecological details if available. An identification key for the freshwater Gammarus of Iran is provided.

The knowledge about distribution, ecology and species composition of caddisflies of the Balkan Peninsula is still not complete. The ongoing investigations of the last years highlight this area as an important hotspot of caddisfly diversity. Polycentropus ierapetra slovenica has been considered a narrow range endemic of Slovenia and surrounding areas. Rhyacophila aurata, a species known from many parts of Europe, according to the current knowledge, is absent from a large part of the Balkan Peninsula. In this paper, we present records of these two rare taxa of Trichoptera from the Republic of Kosovo with exact distribution data, based on sampling carried out randomly during 2014 and 2017. Polycentropus ierapetra slovenica was found in several streams in Bjeshkët e Nemuna Mountains and Karadak Mountains. Rhyacophila aurata was found during this investigation at a single locality in Bjeshkët e Nemuna Mountains. The unexpected finding of these two taxa in Kosovo greatly enlarges their known distribution area and makes a contribution towards the better knowledge of distributional patterns of these rare taxa of caddisflies in this part of Europe.

In this study, we systematized available distribution data, obtained from biological databases and relevant literature, for Mexican species belonging to the tribe Phanaeini. The main objectives were to provide an overall description of the distribution records in biological collections, to detect potential sampling biases, to describe the seasonality of collections and to obtain species distribution models using the Desktop GARP algorithm. A total of 5,562 records, corresponding to 32 species in Mexico, were compiled, including the recently described Phanaeus zoque Moctezuma & Halffter, 2017. This compilation includes 784 unique collection records at 325 localities. These records were mainly distributed along the Trans-Mexican Volcanic Belt, the Sierra Madre Oriental and Sierra Madre Occidental mountain ranges and throughout the states of Chiapas and Veracruz. The Mexican High Plateau, the state of Tlaxcala and the Yucatan Peninsula are lacking in records. Distribution maps were created for species of three genera (Phanaeus MacLeay, 1819, Coprophanaeus Olsoufieff, 1924, and Sulcophanaeus Olsoufieff, 1924) and for 29 species present in Mexico. These species distributions are largely delimited by geomorphological features and vegetation types and coincide with expert descriptions of this tribe; some species show expanded distribution ranges. These maps provide a starting point for further analyses, the planning of future field studies, and the verification of possible new species in the Mexican territory.

Graphene family nanomaterials, with superior mechanical, chemical, and biological properties, have grabbed appreciable attention on the path of researches seeking new materials for future biomedical applications. Although potential applications of graphene had been highly reviewed in other fields of medicine, especially for their antibacterial properties and tissue regenerative capacities, in vivo and in vitro studies related to dentistry are very limited. Therefore, based on current knowledge and latest progress, this article aimed to present the recent achievements and provide a comprehensive literature review on potential applications of graphene that could be translated into clinical reality in dentistry.

Isoetes dubsiisp. nov. and I. santacruzensissp. nov., two new species from lowland areas in South America, are described, illustrated and compared to similar species. Isoetes dubsii can be distinguished from other species of the Brazilian Pantanal wetlands by a set of characters including leaves that are long, flexuous and trigonal in transverse section, tri-lobate stems, rudimentary velum, pustulate megaspores of 310‒390 µm diameter and laesurae of the megaspore at least four times wider than high. Isoetes santacruzensis has flexuous, filiform leaves, 0.4–0.8 mm wide at mid length and reaching up to 15 cm long, black or reddish-black sporangia, sclerified phyllopodia and sparsely verrucate megaspores of 320‒390 µm in diameter. We also include a key for species from the Brazilian Pantanal wetlands and Bolivia and spore images for all species that are discussed. Isoetes dubsii and I. santacruzensis are only known from their type localities and they may deserve special attention concerning their conservation status. However, based on our current knowledge on these species and according to IUCN Red List criteria, they are assessed here as data deficient (DD).

Abstract A review of the current knowledge on the diversity of inquiline oak gall wasps (Hymenoptera: Cynipidae: Cynipinae) from Colombia is conducted for the first time. A new species, Synergus dawnus Lobato-Vila and Pujade-Villar, is formally described and illustrated, and an undescribed specimen from the same genus is diagnosed and discussed. New biological, morphological, and distribution data of the only two previously known species from this country (Synergus colombianus Nieves-Aldrey, 2005 and Synergus pedroi Pujade-Villar, Lobato-Vila, and Fernández-Garzón, 2017), as well as an identification key to the Colombian species of Synergus Hartig, 1840, are provided. The morphological variability of the Colombian species of Synergus, especially of S. pedroi, is discussed.

Censuses were conducted from 15 June to 6 July and from 15 to 24 October 2003 throughout Lake Titicaca to determine the current distribution and abundance of the Titicaca Flightless Grebe Rollandia microptera. We surveyed 22 of an estimated 25 local population distribution ranges. We defined these as shallow offshore feeding areas in combination with coastal beds of tule-rushes (Schoenoplectus tatora). At this large spatial scale we found variously sized populations of grebes in all 22 of the areas surveyed and a negative correlation between the total area of tule-bed within each area and grebe density. Absolute counts of grebes pooled across all sites produced a total of 2,582 individuals on Lake Titicaca. Given that some sites were either partially surveyed or not surveyed at all we feel that this is an underestimate of the total lake population. Limitations in methodologies used precluded the classification to development stage of approximately 43% of the individuals counted. Among the remaining 57% of the individuals counted we identified 732 mature adults within the total population of Lake Titicaca. When combined with information from other sources and current knowledge of habitat fragmentation our results support the classification of the species in the IUCN Red List as Endangered under criterion C2a. Of 20 local fisherman interviewed on the Bolivian side of Lake Titicaca, 90% confirmed that individuals of Titicaca Flightless Grebe incidentally drown in their fishing nets although responses varied from weekly to monthly estimates of by-catch. Although this study provides the first estimate of the total population of Titicaca Flightless Grebes on Lake Titicaca, a standardized monitoring programme will be required in order (1) to provide a baseline for the interpretation of future population trends in the context of impacts generated by human activities and (2) to aid in future management decisions for the long-term conservation of the species.

Local Sampling

Spatial variations of polychaetes along the Baja California Peninsula continental shelf were analysed in two ways: (1) by evaluating the species richness and defining the faunal assemblages from local sampling, and (2) by characterizing the latitudinal variation of beta-diversity based on the distribution of all polychaetes reported up to now. Twenty-seven stations from three oceanographic expeditions were sampled, and 2858 individuals from 38 families and 231 species were identified. Polychaetes were abundant (mean = 37.5 ind 0.1 m−2) and diversified (mean = 15 species station−1). Differences in species composition defined seven faunal assemblages, but their number of species did not show significant latitudinal changes. The beta-diversity analysis was based on distribution data of 730 species from 47 families. The presence of a group of islands in the middle Gulf could have a negative effect on the species distribution, since the lowest values of βT-diversity (0.39) were found in the northern Gulf, but their species were different from those recorded in the central region. The wide variation in βT-diversity (0.5–0.87) showed latitudinal changes in the species composition, mainly in the Gulf mouth (0.86–0.87), which indicated that the fauna inside the Gulf was different from that inhabiting the Pacific coasts. The ICE and Chao2 estimators showed that the polychaetes in the study area are relatively well known (>80%), and that most species (415) have small distribution ranges. The effects of these infrequent species were similar at each latitudinal band, which suggested that the observed βT-diversity pattern could represent a suitable estimation.

The focus of this study is on Preussia sensu lato species with 8-celled ascospores. Two new species, P. alpina and P. octocylindrospora are introduced based on morphological characters and discussed in relation to similar species in the genus. New records are provided from Sporormiella corynespora, S. octomegaspora, P. octomera and P. octonalis. This greatly expands or reduces their geographical distribution ranges, as well as substrate preferences. In addition, a key to the coprophilous species with 8-celled ascospores is provided.

Four, morphologically similar species of crested newts (genus Triturus) meet and hybridize in Serbia, making a complex system with several hybrid zones. The puzzling and rapidly changing taxonomic status of crested newts has been a major issue in getting hold of their distribution. We provide an overview of the current knowledge on Triturus taxonomy and compile available faunistic data into a distribution map, highlighting the species contact and hybrid zones. At the present state of faunistic and genetic research, the northwestern , northeastern , Eastern and southeastern parts of Serbia transpire as areas that are exceptionally important for the diversity of crested newts.
