Opis:
This study investigated the extend to which the snail Columella edentula is more strongly associated with the small balsam Impatiens parviflora than with other plants in the herb layer of an oak-hornbeam forest, and to interpret the character of the interaction Impatiens parviflora - Columella edentula. Numbers of C. edentula and rates of colonization were compared on various plant species under natural and laboratory conditions. Seasonal variation in snail abundance on I. parviflora was observed on permanent plots. The leaf injuries caused by C. edentula were localized in respect of the morphological and anatomical structure of leaves. The results show that I. parviflora is one of the plant species of the herb layer that are most abundantly colonized by this snail in oak-hornbeam forest. Snail finds a plant particularly suitable as a place for resting. The most favoured attachment site is on the underside of the leaf, along the midrib, which provides the highest and relatively stable humidity, as well as protection from direct sunlight and predators. I. parviflora is also a food for the snails, but they do not eat these fragments of leaves where calcium carbonate is accumulated.

Opis:
Laboratory tests using image analysis are one of the types of experimental methods in plant protection. They are used in the evaluation of crop damage by pests, also useful in testing the effectiveness of active substances of plant protection products. The most popular of these analyses are the so called “circular tests”, comprising in administering to the insects and snails the fragments of leaves and measuring the amount of consumed surface. The paper presents a method of analysis of damage to lettuce leaves using ImageJ application. The way of presenting the results was also proposed. This procedure can be used in various analyses of biological sciences and evaluating the dietary preferences of pests. Access to the application ImageJ is free, and flexible configuration allows for any setting parameters of the program, the opportunity to work in different environments and low system requirements allow you to make many accurate measurements in a short time without the need to purchase expensive specialized hardware.
Testy laboratoryjne z zastosowaniem analizy obrazu stanowią jeden z rodzajów metod eksperymentalnych w ochronie roślin. Są one wykorzystywane podczas oceny uszkodzeń roślin przez szkodniki, użyteczne także w testowaniu skuteczności działania substancji aktywnych środków ochrony roślin. Najpopularniejsze wśród takich analiz są tzw. „testy krążkowe”, polegające na podawaniu owadom, ślimakom fragmentów liści i mierzeniu wielkości konsumowanej powierzchni. W artykule zaprezentowano metodę służącą do analizy uszkodzeń liści sałaty przy zastosowaniu aplikacji ImageJ. Zaproponowano również sposób przedstawiania uzyskanych wyników. Procedura ta może znaleźć zastosowanie w różnych analizach biologiczno-przyrodniczych oraz podczas oceny preferencji pokarmowych szkodników. Dostęp do aplikacji ImageJ jest darmowy, a elastyczna konfiguracja, pozwalająca na dowolne ustawienie parametrów programu, możliwość pracy w różnych środowiskach systemowych i niewielkie wymagania sprzętowe umożliwiają wykonanie wielu dokładnych pomiarów w krótkim czasie bez konieczności zakupu drogiego specjalistycznego sprzętu.

Opis:
Small round holes in the tests of fossil echinoids present problems of interpretation, the most obvious questions being who did it and why? Both have been the cause of considerable conjecture by ichnologists and echinoderm palaeontologists. “Drill holes” described from the Miocene of Poland in the echinoid Echinocyamus linearis Capeder are classified within the ichnospecies Oichnus simplex Bromley. Contrary to the original analysis, the possibility remains that some of these holes were the result of eulimid parasitism rather than predation by juvenile cassids. If other, larger echinoids in the fauna suffered predation by adult cassids, then the available samples are probably too small for it to be recognised.

Opis:
Drill holes on tests of Echinocyamus linearis from the Middle Miocene Korytnica Basin represent the first well documented fossil record of cassid predation from Poland. These traces complement the ecological information on the size and structure of cassid populations recorded by body fossils. The high number of drill holes recognised from the Heterostegina Sands, the uppermost part of the Korytnica depositional sequence, indicates the occurrence of a large cassid population during the late stage of development of the Korytnica Basin. The small size of most of the drill holes indicates that juvenile gastropods of the family Cassidae, which are not preserved in the fossil record of the investigated area, were also present in the cassid populations.

Opis:
The molluscicidal activity of six monoterpenes and two phenylpropenes against Theba pisana adults was evaluated using fumigation and direct contact methods. In the fumigant toxicity assay, (-)-citronellal showed the highest toxicity with LC50 value of 7.79 µl · l−1 air after 24 h of treatment, followed by (-)-terpinen-4-ol (LC50 = 12.06 µl · l−1), (-)-menthone (LC50 = 12.28 µl · l−1 air) and p-cymene (LC50 = 16.07 µl · l−1 air). Eugenol and trans-cinnamaldehyde were the most potent contact toxicants against T. pisana. Their LD50 values were 0.18 and 0.29 mg · snail−1 after 24 h of treatment, respectively. These two compounds were more toxic than a reference molluscicide, methomyl. In contrast, α-terpinene and (-)-citronellal were the least toxic compounds. In another experiment, the synergistic effect of piperonyl butoxide (PBO) on tested monoterpenes and phenylpropenes by topical application was examined. The results showed that the toxicity of the tested compounds was increased when mixed with PBO at a ratio [compound/PBO (1 : 2)] except for α-pinene and (-)-terpinen-4-ol in which the toxicity of binary mixtures was less than for single compounds. The synergistic effect of PBO improved with increased exposure time. The highest synergistic effect was observed with (-)-menthone and α-terpinene with synergistic ratios of 9.25 and 4.37, respectively. Monoterpenes and phenylpropenes and their mixtures with PBO described herein merit further studies as potential T. pisana control agents.

Opis:
The main goal in gene therapy and biomedical research is an efficient transcription factors (TFs) delivery system. SNAIL, a zinc finger transcription factor, is strongly involved in tumor, what makes its signaling pathways an interesting research subject. The necessity of tracking activation of intracellular pathways has prompted fluorescent proteins usage as localization markers. Advanced molecular cloning techniques allow to generate fusion proteins from fluorescent markers and transcription factors. Depending on fusion strategy, the protein expression levels and nuclear transport ability are significantly different. The P2A self-cleavage motif through its cleavage ability allows two single proteins to be simultaneously expressed. The aim of this study was to compare two strategies for introducing a pair of genes using expression vector system. We have examined GFP and SNAI1 gene fusions by comprising common nucleotide polylinker (multiple cloning site) or P2A motif in between them, resulting in one fusion or two independent protein expressions respectively. In each case transgene expression levels and translation efficiency as well as nuclear localization of expressed protein have been analyzed. Our data showed that usage of P2A motif provides more effective nuclear transport of SNAIL transcription factor than conventional genes linker. At the same time the fluorescent marker spreads evenly in subcellular space.

Opis:
The second site of Pupilla alpicola (Charpentier) was found in Poland in 2010. It is a treeless alkaline fen located close to the village of Czarny Dunajec (Nowy Targ region, S. Poland). The site is the north-western extension of the Western Carpathian distribution of the species, being more than 30 km away from the previously known Polish site near Niedzica village and also from its known sites in Slovakia. The first recent record of Pupilla pratensis (Clessin) in Poland was found in the north-eastern most part of Poland close to the border with Lithuania, in the vicinity of the village of Rowele. It is an extension of the species' distribution in NW. Europe and also the eastern most known record of this taxon. Both species are exclusive inhabitants of calcareous fensand fen meadows, highly endangered and mostly isolated, and deserve attention of nature conservation agencies.They seem to be very rare in Poland, because no further population was documented at 25 suitable alkaline fen sites sampled mainly in 2010 and 2011 across the southern and eastern part of Poland.

Opis:
In order to assess the effect of alternating electromagnetic and direct magnetic field on adult Helix aspersa O. F. Müller and their eggs, adults and eggs of H. aspersa maxima Taylor and H. aspersa aspersa O. F. Müller were exposed to such fields with different parameters, and the following life cycle traits were observed: condition of hibernating adults, their survival rate during hibernation and reproduction, egg mass, hatching success, growth rate of hatchlings and body mass of next generation adults. Adults were exposed to sinusoidal, alternating electromagnetic fields of 50 Hz, 100 Hz and 200 μT, and magnetic induction of 50 Hz, as well as a field of 175 μT and 10–1000 Hz (repetition period 80 minutes). Egg batches were exposed to direct magnetic fields of magnetic induction 5 μT and 10 μT and alternating electromagnetic fields of analogous induction and frequency of 50 Hz. The effects varied depending on the parameters of the fields, subspecies and life cycle stage. Adult H. aspersa maxima was more sensitive to the changes in characteristics of electromagnetic field than H. aspersa aspersa, but the two subspecies showed a similar reaction to exposing their eggs to direct or alternating magnetic field. Probably direct field had a greater selection effect compared to alternating field, removing weaker genotypes at embryonic stage; this resulted in a greater mean body mass of the next generation adults. The results are preliminary; further studies, with further modifications of parameters of the fields applied are necessary.
