In the era of next‐generation sequencing (NGS) species detection can be performed using environmental samples. However, especially in the case of the main mitochondrial molecular marker, COI, co‐amplification of nuclear mitochondrial pseudogenes—numts or “COI‐like” sequences was noted. Moreover, sequences of co‐occurring non‐target taxa, such as mi...

Bacterial endosymbionts of aquatic invertebrates remain poorly studied. This is at least partly due to a lack of suitable techniques and primers for their identification. We designed a pair of non-degenerate primers which enabled us to amplify a fragment of ca. 500 bp of the 16S rRNA gene from various known bacterial endosymbiont species. By using...

Researchers, governments, agencies, food producers and the civil society are increasingly concerned about ‘emerging food risks’. It is recognised that the successful identification of emerging risks is at the heart of protecting public health and the environment, and that this requires worldwide cooperation between all parties involved in the food...

Abstract The currently applied approaches, procedures and tools used for the identification of emerging risks vary greatly among Member States of the EU. EFSA established a structured approach for emerging risk identification that mainly consists of systematically searching, collecting, collating and analysing information and data. In addition, EFS...

The cytochrome c oxidase subunit I (cox1) gene is the main mitochondrial molecular marker playing a pivotal role in phylogenetic research and is a crucial barcode sequence. Folmer’s “universal” primers designed to amplify this gene in metazoan invertebrates allowed quick and easy barcode and phylogenetic analysis. On the other hand, the increase in...

The list of incorrectly flagged cox1 gene fragment sequences of Gastrotricha originated from another metazoan species. (DOCX)

Although large branchiopods are undoubtedly an important part of the temporary water bodies, they remain the least studied group of macroinvertebrates inhabiting freshwaters. One of these species is the fairy shrimp Branchipus schaefferi. Its known occurrences across the central Europe are limited almost exclusively to temporary pools on military t...

Supplementary file for Celewicz, Czyż, Gołdyn 2018: Feeding patterns in Eubranchipus grubii (Dybowski 1860) (Branchiopoda: Anostraca) and its potential influence on the phytoplankton communities of vernal pools. Journal of Limnology, 77(2):276-284

Filtration patterns in the fairy shrimp Eubranchipus grubii were analysed under laboratory conditions using water containing phytoplankton from their actual locality in western Poland. After 48 hours of feeding, we compared the structure of algal communities in water samples in treatments with males, females and control. The mean filtration rate fo...

The following paper presents the results on the determination of the diversity of species from the Phytophthora genus occurring in the declining oak stands in Krotoszyn Plateau in Poland. From the 50s of the last century, significant deterioration of oak health was observed in these stands, and Phytophthora species were suggested as one of the fact...

In the crustacean Branchipus schaefferi cercopods are brightly coloured caudal rami at the end of the abdomen. The specific life environment of B. schaefferi (highly turbid puddles) may suggest that besides their mechanical function, cercopods may also play an ornamental role to attract a potential mate. We performed standardized major axis regress...

The paper presents data on 20 freshwater snail species: Planorbis planorbis, P. carinatus, Anisus spirorbis, A. leucostoma, A. septemgyratus, A. vortex, A. vorticulus, Bathyomphalus contortus, Gyraulus albus, G. laevis, G. acronicus, G. rossmaessleri, G. riparius, G. crista, Hippeutis complanatus, Segmentina nitida, Planorbarius corneus, Menetus di...

The morphology of resting eggs was studied in Polish populations of 7 large branchiopod species: Branchipus schaefferi, Chirocephalus shadini, Eubranchipus grubii (Anostraca), Lepidurus apus, Triops cancriformis (Notostraca), Lynceus brachyurus (Laevicaudata), and Cyzicus tetracerus (Spinicaudata). Scanning electron microscope photographs for each...

We studied the diet of the American mink (Neovison vison) in small artificial watercourses located in a farmland area of the Barycz River valley in Poland. Rodents, mainly Microtus spp., were the most frequent prey identified, occurring in 88.3% of all analyzed mink scat. Minks also fed willingly on fish, birds and amphibians, whereas insects, cra...

The paper presents data on 13 freshwater snail species: Theodoxus fluviatilis, Viviparus contectus, V. viviparus, Melanoides tuberculata, Bithynia tentaculata, B. leachii, Potamopyrgus antipodarum, Lithoglyphus naticoides, Marstoniopsis insubrica, Valvata cristata, V. pulchella, V. piscinalis and Borysthenia naticina, recorded over the last fifty y...

The morphology of the postembryonic stages of a new quill mite species, Chenophila platyrhynchos sp. nov., parasitising the Mallard Anas platyrhynchos (Linnaeus) (Aves: Anseriformes) in Poland is described in detail. This species is morphologically very similar to Ch. kanduli Bochkov known from Anas querquedula Linnaeus in Russia and differs from i...

First records of Isohypsibius pushkini Tumanov, 2003 (Tardigrada, Eutardigrada, Hypsibiidae) from Poland First records of Isohypsibius pushkini from small ponds in western Poland are described. So far, these are the only records of this species apart from its type locality in Russia. We present some remarks on the ecology of the species, as well. M...
