This paper presents data on 23 beetle species recorded for the first time from the Białowieża Forest (Polish part), and among them two species new for the fauna of Poland. All the beetles were collected using multifunnel (Lindgren) traps, placed in the the selected sites of the study area in 2018. Collected species belong to 13 families: Carabidae (1 species), Corylophidae (1), Curculionidae (1), Dermestidae (1), Elateridae (2), Eucnemidae (1), Laemophloeidae (1), Latridiidae (2), Nitidulidae (1), Ptinidae (3), Staphylinidae (7), Throscidae (1) and Trogossitidae (1). Episernus angulicollis C. G. Thomson, 1863 and E. tatarinovae Toskina et Nikitsky, 2003 (Ptinidae) are recorded for the first time from Poland, and Microrhagus pyrenaeus Bonvouloir, 1872 (Elateridae) and Leptusa norvegica Strand, 1941 (Staphylinidae), for the second time. Distribution of all the above species in Poland is briefly discussed and details on the biology of some of them are given. An identification key for the species of the genus Episernus C. G. Thomson, 1863 from Central Europe is presented. Species diversity of beetles in the Polish part of Białowieża Forest is estimated based on published data.

Attentional Lapses

The worst performance rule (WPR) describes the phenomenon that individuals’ slowest responses in a task are often more predictive of their intelligence than their fastest or average responses. To explain this phenomenon, it was previously suggested that occasional lapses of attention during task completion might be associated with particularly slow reaction times. Because less intelligent individuals should experience lapses of attention more frequently, reaction time distribution should be more heavily skewed for them than for more intelligent people. Consequently, the correlation between intelligence and reaction times should increase from the lowest to the highest quantile of the response time distribution. This attentional lapses account has some intuitive appeal, but has not yet been tested empirically. Using a hierarchical modeling approach, we investigated whether the WPR pattern would disappear when including different behavioral, self-report, and neural measurements of attentional lapses as predictors. In a sample of N = 85, we found that attentional lapses accounted for the WPR, but effect sizes of single covariates were mostly small to very small. We replicated these results in a reanalysis of a much larger previously published data set. Our findings render empirical support to the attentional lapses account of the WPR.

Abstract RFLP and sequences of ITS-rDNA of 45 populations of cyst-forming nematodes collected from different parts of Iran were analysed and identified as representatives of 21 species. Eight enzymes generated RFLP for all studied populations. Comparison of RFLP profiles and sequences of the ITS regions with published data confirmed the presence of Heterodera avenae, H. filipjevi, H. glycines, H. hordecalis, H. latipons, H. schachtii and H. trifolii in Iran. RFLP patterns and ITS sequences for H. elachista, H. turcomanica, H. mothi and C. cacti were obtained for the first time in this study. Heterodera humuli, H. goettingiana, H. fici, H. elachista, H. turcomanica and Cactodera cacti are recorded for the first time in Iran. These results correspond with morphological and morphometric identification of the populations. Several populations were not identified at the species level and are attributed to Heterodera sp.; some of these may correspond to new species. Twenty-one new sequences from Iranian cyst-forming nematodes and 36 known sequences were used for the phylogenetic analyses. The cyst-forming nematodes formed several clades corresponding to their morphological features. Heterodera mothi and H. elachista clustered with high support with other Cyperi group species and H. turcomanica formed a moderately to highly supported clade with the Humuli group.

Abstract: Inventories in Brazilian restingas have been indicating that Myrtaceae are the plant family with the greatest richness of insect galls. A compilation of published data plus new records was elaborated with the aim of stablishing the number of gall morphotypes on this family in this physiognomy of the Atlantic Forest, producing a list of galled species, pointing out the predominant gall features, evaluating the taxonomical knowledge of the gallers, listing the associated fauna, and based on host plant endemisms and monophagy proposing the endemism of some galling species. Myrtaceae harbor 111 morphotypes of insect gall (about 75% induced by Cecidomyiidae, Diptera) on 25 host plant species, 15 endemic. Eugenia L. highlights as the plant genus with the highest number of galled species and gall richness. Leaves are the most galled organ. There is a predominance of globoid and fusiform shapes, green color, glabrous surface and a single internal chamber. The taxonomical data on gallers is deficient as many records have been presented at supraspecific levels. The associated fauna is rich and includes parasitoids, inquilines and predators. Twelve species of Cecidomyiidae, a single species of Curculionidae (Coleoptera) and one species of Eriococcidae (Hemiptera) have been associated exclusively with endemic hosts and then are proposed in the present study as endemic too. The geographical distribution of many galls and respective gallers are restricted to the State of Rio de Janeiro, where most inventories have been carried out. For the first time, Eugeniamyia dispar, previously known from a rural area of Rio Grande do Sul and restinga areas of São Paulo, is recorded in the State of Rio de Janeiro.

Alpheid Shrimp

Six rare or little-known genera from the shrimp family Alpheidae are reported from French Polynesia, five of them for the first time. Distribution ranges are significantly extended for the recently described Acanthanas pusillus Anker, Poddoubtchenko & Jeng, 2006 and Richalpheus palmeri Anker & Jeng, 2006, previously known only from two and one type specimens, respectively, from the Philippines. The original description of A. pusillus, based on two females, is completed with the description and illustration of the male cheliped and pleopod; accordingly, the diagnosis of Acanthanas is slightly emended. The genus Leptalpheus Williams, 1965 was not known from French Polynesia before, but is represented there by two species: L. denticulatus Anker & Marin, 2009, previously known from Vietnam, the Philippines and Fiji; and L. pacificus Banner & Banner, 1974, previously considered as a Hawaiian endemic. The genus Prionalpheus Banner & Banner, 1960 is represented in French Polynesia by two species: P. triarticulatus Banner & Banner, 1960, reported for the first time, and P. brachytomeus Banner & Banner, 1971, reported with some doubts (P. cf. brachytomeus) for the first time since the original description. Rugathanas borradailei (Coutière, 1903), a widespread but rather uncommon and easily overlooked species, is also reported for the first time from French Polynesia. Colour patterns are illustrated for all species, this being for the first time for R. palmeri, L. pacificus, P. triarticulatus and P. cf. brachytomeus.

Abstract The COVID-19 pandemic has posed significant challenges globally. Countries have adopted different strategies with varying degrees of success. Epidemiologists are studying the impact of government actions using scenario analysis. However, the interactions between the government policy and the disease dynamics are not formally captured. We, for the first time, formally study the interaction between the disease dynamics, which is modelled as a physical process, and the government policy, which is modelled as the adjoining controller. Our approach enables compositionality, where either the plant or the controller could be replaced by an alternative model. Our work is inspired by the engineering approach for the design of Cyber-Physical Systems. Consequently, we term the new framework Compositional Cyber-Physical Epidemiology. We created different classes of controllers and applied these to control the disease in New Zealand and Italy. Our controllers closely follow government decisions based on their published data. We not only reproduce the pandemic progression faithfully in New Zealand and Italy but also show the tradeoffs produced by differing control actions.

Although the field of otolaryngology has experienced a decline in the number of applicants to our residency programs, otolaryngology remains a highly competitive field with an extremely strong applicant pool. Many highly qualified candidates cannot obtain a position in our field each year, and many of these candidates choose to reapply the next year. Data are lacking regarding reapplicants’ success rate and the best gap year employment and training options for these reapplicants. Reapplicants were studied prospectively via a two-stage survey during the 2014–2015 and 2015–2016 application cycles. Success rates for the overall group were compared to those from published data, and success rates between subgroups were also compared. First-time reapplicants in the study performed extremely well. Their match rate (19/22) was not significantly different from that of traditional otolaryngology applicants (551/619, p = 0.73) and was significantly higher than that of nontraditional applicants not in our cohort (23/62, p < 0.001). No significant difference was found between applicants by employment/training activities, with both researchers (11/12) and surgical interns (8/10, p = 0.57) performing well. Predictors of reapplicant success could not be assessed because only 3 reapplicants in the cohort were unsuccessful. First-time otolaryngology reapplicants remain a highly competitive group of applicants to our field, regardless of employment/training activities undertaken after graduating medical school.

The response of rabbit tongue, placed in a modified Ussing chamber, to salts [KCl, NaCl, NH4Cl, tetraethylammonium chloride (TEACl)], sweeteners (D-glucose, sucrose), acid (HCl), and a bitter tastant, quinine, was investigated for the first time. These experiments were conducted to further explore the new paradigm of taste transduction that correlates changes in the electrical behavior of lingual epithelia with neural responses. In addition, the responses of rabbit tongue data were compared with previously published data on dog and frog tongues. When increases in short-circuit current (Isc) for rabbit tongue induced by hyperosmotic concentrations of several salts were compared, the following sequence was found: KCl greater than NH4Cl greater than NaCl greater than TEACl. These results are consistent with previously published integrated chorda tympani responses (ICTR) as well as behavioral studies that showed that rabbits prefer KCl to NaCl with their natural diet. Pharmacological studies using ouabain and amiloride suggest that K and Na are traversing rabbit tongue through different pathways. The maximal stimulation of Isc by D-glucose and sucrose (in 50 mM NaCl) was significantly smaller than those measured for KCl and NaCl. The rabbit tongue was sensitive to HCl at concentrations less than 1 mM in agreement with ICTR measurements.
