Pond ecosystems harbour substantial biodiversity and contribute to several ecosystem services as nature‐based solutions (NbS). Pond restoration and creation projects have been initiated to address these trends, yet while some insights are published, many remain within the expertise of practitioners and are not easily accessible. Moreover, papers sy...

Perchlorates are present at high concentrations in Martian regolith and pose an additional challenge to the survival of terrestrial life on Mars. Some microinvertebrates can resist extreme conditions (e.g. low temperatures, lack of oxygen and radiation), making them suitable model species for space experiments. Clarification of whether they can tol...

The infamous "master manipulators"-intracellular bacteria of the genus Wolbachia-infect a broad range of phylogenetically diverse invertebrate hosts in terrestrial ecosystems. Wolbachia has an important impact on the ecology and evolution of their host with documented effects including induced parthenogenesis, male killing, feminization, and cytopl...

Anhydrobiosis is a desiccation tolerance that denotes the ability to survive almost complete dehydration without sustaining damage. The knowledge on the survival capacity of various tardigrade species in anhydrobiosis is still very limited. Our research compares anhydrobiotic capacities of four tardigrade species from different genera, i.e. Echinis...

Anhydrobiosis is a desiccation tolerance that denotes the ability to survive almost complete dehydration without sustaining damage. However, knowledge on the survival capacity of anhydrobiosis in various species of tardigrades is still very limited. Our research has compared anhydrobiotic capacities of four tardigrade species: Echiniscus testudo, P...

The infamous “master manipulators” – intracellular bacteria from the genus Wolbachia – infect a broad range of phylogenetically diverse hosts in terrestrial ecosystems.

The aim of this study was to determine the impact of the introduction of Pinus sylvestris on the mesofauna of the forest floor in the Central European oak-hornbeam forest, using gastropods as a model group. Data on terrestrial gastropods and environmental variables were collected in 2012–2014 from 25 study plots (14 without pine and 11 with pine) a...

Water availability is one of the most important factors for terrestrial life. Terrestrial habitats may periodically become dry, which can be overcome by an organism's capability to undergo anhydrobiosis. In animals, this phenomenon has been reported for invertebrates, with tardigrades being the best-known. However, different tardigrade species appe...

Temporary water bodies, especially vernal pools, are the most sensitive aquatic environments to climate change yet the least studied. Their functioning largely depends on their phytoplankton community structure. This study aimed to determine how temperature and photoperiod length (by simulating inundation in different parts of the year under five c...

We used high-throughput sequencing of 16S rRNA to test whether tardigrade species are infected with Wolbachia parasites. We applied SILVA and Greengenes databases that allowed taxonomic classification of bacterial sequences to OTUs. The results obtained from both databases differed considerably in the number of OTUs, and only the Greengenes databas...

Temporary water bodies, especially vernal pools, are the most sensitive to climate change, yet the least studied aquatic environments. Their functioning largely depends on the phytoplankton communities structure. This study aimed to determine how temperature and photoperiod length (simulating inundation in different parts of the year under six clim...

Abstract.— Applying an integrative taxonomy approach, we describe a new tardigrade species from Nepal. Light and scanning electron microscopy are used for morphological as well as morphometric analysis of the new species. Furthermore, multilocus molecular data (nuclear markers, i.e., 18S rRNA, 28S rRNA, ITS-2 and mitochondrial COI barcode sequences...

We investigated vertical migration distances of Vertigo moulinsiana (Dupuy) in conditions of (1) 24-hour illumination and (2) 24-hour darkness. The experiments were carried out in the laboratory, at high and constant humidity (RH 100%), and 22 °C temperature. The snails were placed singly in 150 cm long, vertically oriented transparent plastic tube...

Global knowledge of tardigrade diversity is limited, and there still are regions with poorly studied fauna, such as Nepal. We applied an integrative taxonomy approach to describe a new tardigrade species from this area. The presented analysis was based on morphological and morphometrical data (using both light and scanning electron microscopy) and...

Studies on Antarctic tardigrades started at the beginning of the twentieth century and have progressed very slowly and ca. 75 tardigrade species are known from this region. Paramacrobiotus fairbanksi was described from USA based on genetic markers and later reported from Italy, Poland, and Spain. The "everything is everywhere" hypothesis suggests t...

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...

Large branchiopod crustaceans are among the most threatened freshwater invertebrates of the world. They are regarded as a flagship group in the conservation of temporary waters, and knowledge of their ecology and conservation has developed rapidly in recent years, especially in the Mediterranean region. Little is known, however, about population fu...

The aim of this study was the evaluation of the relationship between the presence of tardigrades and various levels of sewage pollution in different tanks of a wastewater treatment plant. The study was carried out in the wastewater treatment plant located near Poznań (Poland) during one research season. The study was conducted in a system consistin...

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...

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...

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...

Overwintering strategies of land snails are poorly known. This knowledge, however, would help planning effective conservation measures of rare and endangered species. We studied overwintering of two snail species, Vertigo moulinsiana and V. angustior, having high conservation priority according to the European Union Habitat Directive. The study was...

We are reporting the first locality of invasive giant African snail, Achatina (Lissachatina) fulica (Férussac, 1821) in the Ecuadorian Amazon. It was found present in 32 out of 50 urban sites studied. The abundance where present was relatively high when compared to literature from other parts of the world. The snails were found in aggregations, usu...

Using non-lethal methods is especially important for the monitoring and conservation planning of endangered species and their habitats. The goal of this study is to check whether the current method of monitoring endangered micro-snail populations by soil sampling, which involves killing the snails and altering their microhabitat, could be replaced...

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...

Several pulmonary snails search for and / or follow trails left by their species for purposes such as feeding, aggregation and reproduction. In the project characterization of the ecological behavior under controlled conditions among the individuals of the species Lissachatina fulica to know the frequency with which they follow the trail and direct...

Zoogeographical studies on Tardigrada are limited by the extent of our knowledge on tardigrade taxonomy and faunistics. In this paper we analyse the relationships between the tardigrade fauna of North, Central and South America (Nearctic and Neotropical regions) and provide the first test of whether the tardigrade fauna of the Americas has undergon...

Milnesium, with its relatively short and wide buccal tube, is considered carnivorous. Species in this genus exhibit differences in buccal tube length, standard buccal tube width, and the buccal tube length/width ratio. To determine whether buccal tube size is correlated with the type of prey, ˜4000 specimens of various Milnesium species were examin...

Abstract: Distribution data on Achatina fulica Bowdich were obtained from pest control agencies and from a survey of potential localities randomly distributed in all provinces of Ecuador. Among the total of 1,236 localities, 1,065 (86.2%) held populations of the species. The snail was found to spread much faster than predicted and was present in ar...

The diet of nestling Hooded Crows (Corvus cornix) was investigated in Warta Mouth National Park (W Poland) in the breeding season of 2003. We analyzed 82 food samples of which 79% contained snails and bivalves. Hooded Crows prefer Viviparus spp. instead of smaller but more abundant molluscan species present in the studied area. We suspect that unde...

Underground nests of Talpa europaea, known as the common mole, are very specific microhabitats, which are also quite often inhabited by various groups of arthropods. Mites from the suborder Uropodina (Acari: Mesostigmata) are only one of them. One could expect that mole nests that are closely located are inhabited by communities of arthropods with...

Eucobresia diaphana (Draparnaud) is a European land snail which is distributed from France in the west to Bulgaria in the southeast. It is listed in the Red List of Threatened Species in Poland where it occurs in the Sudetes; its range is mainly limited to Lower Silesia. We found five localities of E. diaphana in the Lubuskie province (W. Poland),...

The aim of this study was to evaluate whether simple geographical data can be used to predict the probability of the presence of two threatened snail species: Vertigo angustior and V. moulinsiana, occurring within wetland areas across their central European range. Our research was based on data from 226 localities across Poland fitting with the spe...

The genus Milnesium Doyère, 1840 is known from many localities, from the Antarctic through tropical and temperate to the Arctic regions. Since the nominal species of genus was recently redescribed many new records and species have been reported from numerous localities throughout the world. Currently, the genus Milnesium comprises 25 valid taxa. Sp...

According to the most widely accepted opinion, Central America owes its high biodiversity to the mixed influence of zoogeographical elements of neighbouring South and North Americas. Approximately three to five million years ago a corridor, connecting previously isolated Neotropical and Nearctic faunas, allowed a rapid interchange between species;...

ABstract: New localities of Vertigo geyeri Lindholm, V. moulinsiana (Dupuy) and V. angustior Jeffreys were found in 2011–2014, in three provinces in Poland: Wielkopolskie, Lubuskie and Podlaskie.

Basic information on biology, ecology and monitoring methods in Polish populations of Natura2000 protected freshwater snail species, Anisus vorticulus (Troschel, 1834)

Shorebird (Charadriiformes) migration phenology is critically synchronised with prey availability at traditional staging sites that allows the birds to stage and complete the migrations. These stopovers, usually in large concentrations, make the migrants vulnerable to local predators. The body mass gained or maintained is considered to be the resul...

Two populations of the fairy shrimp Eubranchipus grubii (Dybowski, 1860) and one population of Branchipus schaefferi Fischer, 1834 from Poland were studied cytogenetically. The aim was to confirm their diploid chromosome numbers and chromosome morphology, as well as to reveal the distribution of nucleolar organizer regions (NORs) and the course of...

Over 700 moss, lichen and hepatic samples were collected from territory of Costa Rica. Tardigrades were present in nearly half of the samples. Overall, more than 7000 tardigrades were found. All specimens were identified as 64 species belonging to 18 genera. The number of species per positive sample varied between 1 and 10, but on average it did no...

We examined the species composition and community structure of mites of the order Mesostigmata (Acari) in nests of the Eurasian griffon vulture (Gyps fulvus Hablizl, 1783) in Croatia. Material collected from 18 nests included 565 mites belonging to seven species. The most abundant species were Leiodinychus orbicularis (C.L. Koch, 1839) (Trematurida...

Fifteen moss samples collected in the Sophia Province (Bulgaria) were examined. In these samples six eutardigrade species were found: Hypsibius convergens, Isohypsibius prosostomus, Macrobiotus binieki sp. nov., M. hufelandi, M. pallarii and Ramazzottius oberhaeuseri. The new species belongs to the Macrobiotus harmsworthi group and differs from the...

Populations of Helix pomatia L. in Poland have been commercially exploited since 1951; the snails are mostly exported. The growing interest in the Roman snail on the European market has resulted in its increased exploitation, in some areas leading to a considerable decrease in its abundance. Introducing export quota in 1964 did not prevent overexpl...

Studies on the distribution and abundance of Cochlodina laminata, Ruthenica filograna and Clausilia bidentata in wintering conditions were based on a network of four permanent monitoring plots. Of the three clausiliids present, C. laminata was the most widely distributed, while the occurrence of R. filograna was limited to one plot. The small distr...

The aim of our study was to as- sess the small scale distribution (up to several m 2 ) of hibernating forest-dwelling snails in relation to small-scale environmental factors, like litter com- position, soil temperature and humidity or vegeta- tion cover. The study was conducted in the "Dębno nad Wartą" (local name) natural reserve, western Poland,...

The Hooded Crow (Corvus cornix) is often considered the main nest predator of many bird species, especially water- birds. Such relationship should be particularly clear during the breeding season in wetlands, when the need to supply their nestlings with the highest quality foods forces predators to intensify their hunting activities. Hence, waterbi...
