Presence of uradenia in male adults of the genus Dismegistus (Hemiptera: Heteroptera: Parastrachiidae)
2018
Uradenia, often referred to as paragenital glands, are usually voluminous paired exocrine glands located ventrally in the abdomen mostly on the intersegmental membrane between abdominal segments (= urites) VII-VIII or VIII-IX, depending on sex or the taxon. They have been previously recorded from eight pentatomomorphan families belonging to Coreoidea, Lygaeoidea and Pyrrhocoroidea (Hemiptera: Heteroptera), found either in males, females or both sexes, and were thought to be absent in Pentatomoidea. We report here the first instance of uradenia in a pentatomoid genus, the African Dismegistus Amyot & Serville, 1843 (Parastrachiidae). Only the male adult possesses uradenia located on the i…
New insight into the systematic position of the endemic Madagascan genus Amberiana (Hemiptera: Heteroptera: Dinidoridae) using 12S rDNA sequences
2015
The systematic position of the endemic Madagascan genus Amberiana Dist. İs studied using DNA sequences (the mitochondrial 12S rDNA subunit) for the first time. The phylogenetic relationships within the superfamily Pentatomoidea were computed using neighbor-joining, maximum parsimony, minimum evolution, and maximum likelihood methods, as well as Bayesian estimation. All results based on the mtDNA analyses stand in contrast with previous morphological data. The mtDNA analysis showed close relationships of the genus Amberiana to the genus Sehirus (Cydnidae: Sehirinae) and to species of the family Parastrachiidae, whereas the morphology indicated that the genus was a typical representative of t…
Tibial combs in the Cydnidae (Hemiptera: Heteroptera) and their functional, taxonomic and phylogenetic significance
2005
Tibial combs in representatives of the family Cydnidae are described in detail for the first time. The structure was studied in 98 species of 58 genera representing all the subfamilies, among them 16 species were investigated using scanning electron microscopic (SEM) techniques. In addition, Parastrachia japonensis (Scott, 1880) of the family Parastrachiidae, and two species of Dismegistus Amyot and Serville, 1843 (a genus of uncertain systematic position within Pentatomoidea) have also been studied. Morphological terminology is proposed for all the structures connected with tibial combs and the term ‘the tibial comb complex’ is suggested; its functional, taxonomic and phylogenetic signific…
Geographic Distribution and Niche Divergence of Two Stinkbugs,Parastrachia japonensisandParastrachia nagaensis
2014
Parastrachiidae is a small stinkbug family containing only one genus and two species, Parastrachia japonensis (Scott) (Hemiptera: Heteroptera: Pentatomoidea) and Parastrachia nagaensis Distant. The geographic distribution of the genus has been poorly studied. Niche conservatism refers to that idea that closely related species are more ecologically similar than would be expected, whereas niche divergence predicts they occupy distinct niche spaces. The existence of only two species within one genus suggests niche conservatism or differentiation might exist among them. Herein, the distribution of the genus was mapped, potential distributions were predicted using ecological niche modeling, and …
Apokalipsa spełniona: casus epidemii AIDS
2020
Disasters are hardly ever unequivocal. Any attempt to sort them out remains a forever open task. A natural part of everyday life in the past, disasters have been reinvented by the modern world as a challenge that essentially needs to be eliminated from public life. Due to the dramatic expansion of humans and human activity, one can hardly call them ‘natural’ anymore. This article focuses on disasters and their significant culture-forming potential, discussing it primarily on the example of the AIDS epidemic. With this new epidemic, the catastrophic vision of history was rekindled and a specific (post-)apocalyptic social climate was created. AIDS, called the plague of the 20th century, reviv…
Psychospołeczne skutki pandemii COVID-19
2021
Pandemia COVID-19 jest poważnym zagrożeniem dla zdrowia publicznego zarówno w aspekcie fizycznym, jak i psychicznym. Na COVID-19 zachorowało już ponad 80 milionów ludzi na świecie, z czego prawie 2 miliony zmarły. Nawet jeśli u większości osób nie dojdzie do zakażenia, są one narażone na psychologiczne konsekwencje epidemii. Występowanie poważnych chorób zakaźnych przyczynia się do wzrostu strachu i lęku wśród społeczeństwa, co potwierdzono również podczas poprzednich epidemii SARS, MERS i grypy H1N1. W związku z rosnącą liczbą przypadków, dużą liczbą zgonów i brakiem wydolności systemów ochrony zdrowia na całym świecie ludzie odczuwają strach przed zarażeniem, śmiercią, powikłaniami i kont…
Kulturowe obrazy epidemii i wizje świata „od nowa”
2022
This article seeks to describe the social and cultural changes in the aftermath of the COVID-19 pandemic. The (post)pandemic landscape turned out to materialise the long-felt visions – dystopias. The metaphors of alienation and exile have proven dramatically real in the age of the general (self-)isolation. Particularly interesting are the social reactions to ‘new’ threats: from epidemic denialism and scepticism to epidemic panic. The biological cataclysm has triggered an avalanche of social antagonisms, contradicting the optimistic (and, it appears, naïve) thesis about the democratic nature of the disease/epidemic. In the context of the events observed since 2020, one may wonder why the wor…
Future anxiety as a predictor of the fear of childbirth
2017
Lęk przed porodem jest zjawiskiem emocjonalnym, którego łagodnych objawów doświadcza większość kobiet, niezależnie od stanu i etapu ciąży. Lęk przed porodem jest zmienną według większości badań oddziałującą na decyzje prokreacyjne, przebieg ciąży i porodu. Lęk przed porodem jako zmienna silnie wpływa na deklarowanie chęci cesarskiego cięcia. Przebadano grupę (N = 350) polskich kobiet, które były zapraszane do badań poprzez przychodnie ginekologiczne. Kobiety wypełniały ankietę mierzącą następujące konstrukty: lęk przed porodem (Putyński, 1997), lęk przed przyszłością (Zaleski, 1996), orientację temporalną (Zimbardo i Boyd, 1999) oraz metryczkę mierzącą zmienne położnicze i demograficzne. Wy…
Non-monophyly of the “cydnoid” complex within Pentatomoidea (Hemiptera: Heteroptera) revealed by Bayesian phylogenetic analysis of nuclear rDNA seque…
2017
The “cydnoid” complex of pentatomoid families, including Cydnidae, Parastrachiidae, Thaumastellidae, and Thyreocoridae, is morphologically defined by the presence of an array of more or less flattened stout setae (called coxal combs), situated on the distal margin of coxae. These structures, suggested to prevent the coxal-trochanteral articulation from injuries caused by particles of soil, sand or dust, by their nature and function are unknown elsewhere in the Heteroptera. As such, coxal combs were regarded as a synapomorphy of this group of families, and enabled the definition of it as a monophylum. In this study, the monophyly of the “cydnoid” complex of families is tested for the first t…
Strach przed COVID-19, percepcja ryzyka i zagrożenia a poziom stresu u polskich pielęgniarek w czasie pandemii COVID-19
2021
Wstęp. Pandemia COVID-19 powoduje silny stres u pracowników ochrony zdrowia, zwłaszcza u pielęgniarek. Pielęgniarki są w grupie osób szczególnie narażonych na zarażenie wirusem. Są również narażone na odczuwanie psychologicznych negatywnych skutków pandemii, takich jak strach, lęk i stres związany z pracą. Cel. Celem badań było określenie związku między strachem przed COVID-19, postrzeganiem ryzyka i zagrożenia a stresem u polskich pielęgniarek podczas pandemii COVID-19.Materiał i metody. W badaniu wzięło udział 106 pielęgniarek. W badaniu wykorzystano Skalę Odczuwanego Stresu (PSS-10), Skalę Strachu przed COVID-19 (FOC-6), Skalę Postrzeganego Ryzyka Zachorowania na COVID-19 oraz Skalę Post…
