Mimesis and mimicry among arthropods
Mimetyzm i mimikra wśród stawonogów
Autorzy:
Barwińska, Wioleta
Opis:
Mimetyzm i mimikra to zjawiska powszechnie występujące wśród stawonogów (Arthropoda). Mimetyzm to zdolność upodabniania się organizmu do otaczających elementów środowiska zewnętrznego, w którym dany osobnik żyje, w celu ochrony przed drapieżnikami. Mimikra to zjawisko polegające na naśladowaniu organizmu modelowego przez organizm zwany naśladowcą, w celu wprowadzenia odbiorcy sygnału (operatora) w błąd.
Mimicry and mimesis are the survival strategies of animals which occur among arthropods in the natural environment. Mimicry is an adaptation of animals that occurs when some animals imitate the appearance or behavior of other animals in order to deceive the predators. Mimesis is an optical deception that occurs when animals resemble the natural objects and the elements of surrounding environment.

Opis:
Cadmium is a toxic heavy metal which can cause numerous alterations in cell functioning. Exposure to cadmium leads to generation of reactive oxygen species, disorders in membrane structure and functioning, inhibition of respiration, disturbances in ion homeostasis, perturbations in cell division, and initiation of apoptosis and necrosis. This heavy metal is considered a carcinogen by the Agency for Toxic Substances and Disease Registry. At least some of the described toxic effects could result from the ability of cadmium to mimic other divalent ions and alert signal transduction networks. This review describes the role of cadmium mimicry in its uptake, reactive oxygen species generation, alterations in calmodulin, Wnt/β-catenin and estrogen signaling pathways, and modulation of neurotransmission. The last section is dedicated to the single known case of a favorable function performed by cadmium mimicry: marine diatoms, which live in zinc deficient conditions, utilize cadmium as a cofactor in carbonic anhydrase - so far the only described cadmium enzyme.

Opis:
This paper reports on a study into the inter-relationships amongst foreign language pronunciation, mimicry ability and a range of personality and attitudinal factors. It will begin with a brief review of studies into affective influences on pronunciation ability (Arnold 1999, Hu & Reiterer 2009) and research into the importance of mimicry talent (Jilka 2009; Piske, MacKay & Flege 2001). This will be followed by a short description of a pilot study carried out prior to the main experiment. In the main study, a group of Polish learners of English completed a number of mimicry tasks in three languages: Italian, Dutch and Chinese, as well as a narration task in English. Mimicry performance and English pronunciation were then assessed by native speakers and compared. Participants also completed a questionnaire concerning their feelings about the languages they were to mimic and a second questionnaire designed to detect affective factors such as language learning anxiety, as well as attitudes towards the pronunciation of Polish and English. The pilot study suggested that the perceived attractiveness of the foreign language to be mimicked did not affect the performance of most participants, and that mimicry skill was fairly constant across languages. However, those who were particularly concerned about their personal appearance showed greater fluctuation in their ability to mimic and their performance appeared to be influenced by their attitude towards the language. This is referred to by the author as the Cecily effect. That study also confirmed the results of my previous experimental work showing that mimicry skill is correlated to some degree with English language pronunciation and that both pronunciation and mimicry are negatively affected by high levels of anxiety. The main study sets out to investigate whether or not these conclusions hold true for a larger sample population and also seeks to determine the effect of confidence and willingness to take risks on scores for both foreign language pronunciation and mimicry exercises.

Opis:
Mimicry is known to produce benefits for the mimicker such as liking, increased prosocial tendencies (e.g., higher donations), and trust. Little is known about the benefits or costs to the mimickee. The aim of this study is to explore this issue. Participants were mimicked or not by a confederate. The confederate then dropped pens and checked if the participants picked them up (a proxy for prosocial behavior). Finally, questionnaires were administered that assessed each participant’s liking of the confederate and self-liking, and self-esteem. As expected, mimicked participants picked up more pens and liked the mimicker more. Surprisingly, mimicked participants reported significantly lower self-like when compared to non-mimicked participants, and their self-esteem tended towards being lower. This research fills an important theoretical gap showing that there is a great cost to mimicry.

Opis:
Nymphalids, the largest lepidopteran family, is represented by altogether 19 species (37% of the total species abundance) from the present study site Taki, West Bengal, India, with multiple habitat profiles exposed to different anthropogenic interventions. Nymphalidae is reported to be with highest occurrence of mimicry, a naturally selected survival tool for lepidopterans. A nymphalid set, including a model [Plain Tiger: Danaus chrysippus (Linnaeus, 1758)] and a mimic component [Danaid Eggfly ♀: Hypolimnus misippus (Linnaeus, 1764)] is selected for studying the specific ecological and functional correlation among them in their natural habitat. Their comparative seasonal and habitat wise distribution shows co-existence, the unpalatable model species outnumbering the mimic, the vulnerable target, corresponding to the Batesian mimicry. The wing morphology pattern is significantly shared, though the larval and adult host plants are exclusive and species specific. The year long field observation indicates the existence of considerable degree of similarity with respect to the ecobiological details, like flight pattern, mudpuddling, resting, basking and alternative resource utilisation activities. Species specific unique foraging attributes is observed. Being potential pollinators, they play key role to maintain the wild floral diversity at landscape level. The study bears conservation value towards these nature’s artwork, acting as the biotope indicator.

Opis:
The article deals with important issues related with the sustainable existence of the Ukrainian society such negative phenomena as social and political mimicry. It considers that political mimicry is generally destructive,and facilitates the adaptation of political actors and their manipulation under citizens consciousness. It is shown that the nature of political mimicry is associated with the necessity of the struggle for power conservation status by political elite. The author defines political mimicry as a means of self-protection in crisis situations. This paper investigates the reasons for political mimicry existence in Ukrainian society, among them the author names „post soviet union „ attributes which are present in Ukrainian politics mental attitudes and behaviors at the level of elites. The author thinks that the main factors, both important components of Ukrainian society political culture which would provide immunity from political mimicry should be considered : the formation and development of public protest activities which demonstrate the appropriate level of political consciousness and culture and the activity of politically critical thinking citizens, specifically reflecting their political consciousness. Nowadays it should be an important feature of Ukrainian society political culture, especially in the context of mimicry politicians activity recognition. Besides it is important to establish real institution of political responsibility in Ukrainian society.
