Effects of a specific task-oriented training versus its combination with manual therapy on balance and mobility in people post stroke at the chronic stage: study protocol for a pilot randomised controlled trial
Authors: Traxler Kristina , Schinabeck Franz , Baum Eva , Klotz Edith , Seebacher Barbara
Published: December 2020

Background: Large studies have shown that stroke is among the most relevant causes of acquired adult disability. Walking and balance impairment in stroke survivors often contribute to a restriction in daily activities and social participation. Task-oriented training (TOT) is an effective treatment strategy and manual therapy (MT) is used successfully to enhance ankle joint flexibility in this population. No study, however, has compared TOT against its combination with MT in a randomised controlled trial. Aims of this pilot study are therefore to explore the feasibility of a full-scale RCT and the preliminary effects of specific TOT with a combined specific TOT-MT versus a control group in people post stroke.Methods: This is a protocol of a 4-week prospective randomised controlled parallel pilot trial in people post stroke at the chronic stage with limited upper ankle joint mobility and an impairment in balance and mobility. At a German outpatient therapy centre using 1:1:1 allocation, 36 patients will be randomised into one of three groups: 15-minute talocrural joint MT plus 30-minute specific TOT (Group A); 45-minute specific TOT (Group B); controls (Group C). Training will be goal-oriented including tasks that are based on daily activities and increased in difficulty ulilising predefined progression criteria. Interventions will be provided face-to-face 2 times per week, for 4 weeks, in addition to 20-minute concurrent x4 weekly homebased training sessions. Data will be collected by blinded assessors at baseline, post-intervention and 4-week follow-up. The primary outcome will be feasibility assessed by recruitment, retention and adherence rates, compliance, adverse events, falls and the acceptability of the intervention. Secondary outcomes will be walking speed, single and dual tasking functional mobility, ankle range of motion, disability and health-related quality of life.Discussion: Results from this study will inform a larger randomised controlled trial to investigate the effects of specific TOT and specific TOT-MT compared to a post stroke control group. We hope that the study findings help to enhance stroke rehabilitation.Trial registration: German Clinical Trials Register, DRKS00023068.

Published: December 2020

Background. Wilms’ tumor 1‐associating protein (WTAP) was previously reported to play critical roles in the tumorigenesis of different malignancies, and its expression level has been linked to a poor prognosis of several cancers. We evaluated the role of WTAP in endometrial carcinoma (EC) using publicly available data from The Cancer Genome Atlas (TCGA). Methods. The relationship between WTAP expression and clinical characteristics was assessed with the Wilcoxon signed‐rank test and logistic regression. Clinical factors associated with prognosis were evaluated using Cox regression analysis and Kaplan-Meier method. Gene set enrichment analysis (GSEA) was conducted using TCGA dataset. Results. Our results revealed that WTAP was significantly up-regulated in EC. Increased WTAP expression in EC was significantly associated with high-grade tumor (odds ratio [OR] = 2.126) and high-risk histology (OR = 1.915) (all P < 0.05). Patients with high WTAP expression had a worse overall survival (OS) (hazard ratio [HR] = 2.868, 95% confidence interval [CI] = 1.259-6.532; P = 0.0087) and recurrence-free survival (RFS) (HR =3.148, 95% CI = 1.372-7.220; P = 0.004) than those with low WTAP expression. Multivariate analysis showed that WTAP expression remained an independent predictor of OS and RFS. Furthermore, GSEA showed that wnt/β-catenin signaling pathway was differentially enriched in WTAP high expression phenotype. Conclusions. WTAP was over-expressed in EC. WTAP expression was an independent predictor of poor OS and RFS in EC, and it was associated with advanced grade, high-risk EC. Moreover, the wnt/β-catenin signaling pathway might be the key process regulated by WTAP in EC.

Published: December 2020

Background: LncRNA ZNFX1 antisense RNA 1 (ZFAS1) is largely reported to be abnormally expressed in various human cancers and associated with unfavorable prognosis. So this study aims to further investigate its clinical value in multifarious cancers.Methods: Databases of PubMed, Web of science, Cochrane library, Embase, Chinese National Knowledge Infrastructure and Wanfang was retrieved to collect eligible studies until October 22, 2020. The clinical role of ZFAS1 was comprehensively assessed by STATA 12.0. Additionally, the CeRNA network in which ZFAS1 involved was constructed. And function analysis of targeted mRNAs was performed by R package “cluster profiler”.Results: 23 studies of 2263 cancer patients met the inclusion criteria in this meta-analysis. The comprehensive results suggested that patients with elevated ZFAS1 expression got poor overall survival (OS) (HR=1.80, 95%CI: 1.50-2.10, P≤0.001), and they are prone to lymph node metastasis (OR=2.67, 95%CI: 1.73-4.14, P≤0.001), distant metastasis (DM) (OR=3.45, 95%CI: 1.61-7.39, P=0.001), advanced TNM stage (HTS) (OR=2.99, 95%CI: 1.97-4.54, P≤0.001), larger tumor size (LTS) (OR=1.54, 95%CI: 1.05-2.24, P≤0.001), poor histologic grade (PHG) (OR=1.57, 95%CI: 1.09-2.26, P=0.015). The CeRNA network and function analysis revealed the potential mechanism which ZFAS1 may involve in cancers.Conclusion: The current analysis revealed that elevated ZFAS1 expression is common in various cancer and was significantly associated with poor OS and clinical characteristics, thus it may function as prognostic biomarker in various cancer. Nevertheless, larger well-designed clinical research a is still warranted to verify our findings.

Background Chemotherapy resistance based on fluorouracil and cisplatin is one of the most encountered postoperative clinical problems in patients diagnosed with gastric cancer (GC), resulting in poor prognosis. Methods This study aimed to combine autophagy-related genes (ATGs) to investigate the susceptibility of victims with gastric malignancy to postoperative chemotherapy. Based on the TCGA database, gene expression data for GC patients undergoing and during chemotherapy were integrated and analyzed. Prognostic genes were screened based on univariate and various analysis regression models. Subjects were divided into high-risk and low-risk groups and analyzed by the median risk score approach. The product limit estimator method was used to evaluate the OS and DFS. The accuracy of the prediction was resolved by the subject curve analysis. In addition, proper analysis carrying out was done in our work for some detailed assessments. The differential expression of ATGs is mainly related to chemotherapy resistance. Results A total of 9 ATGs of chemotherapy administration outcomes in these suffers were screened. Based on GEO and TCGA databases, the model accurately predicted DFS and OS after chemotherapy administration. Conclusions This study established prognostic markers based on 9 genes, predicting that ATGs are related to chemotherapy susceptibility of GC patients, which can provide better individualized treatment regimens for clinical practice.

Published: December 2020

Introduction: HIV self-testing (HIVST) is effective in improving the uptake of HIV testing among key populations. Complementary data on the cost-effectiveness of HIVST is critical for planning and scaling up HIVST. This study aimed to evaluate the cost-effectiveness of a community-based organization (CBO)-led HIVST model implemented in China. Method: A cost-effectiveness analysis (CEA) was conducted by comparing a CBO-led HIVST model with a CBO-led facility-based HIV rapid diagnostics testing (HIV-RDT) model. The full economic cost, including fixed and variable cost, from a health provider perspective using a micro costing approach was estimated. We determined the cost-effectiveness of these two HIV testing models over a two year time horizon (i.e. duration of the programs), and reported costs using US dollars (2020). Results: From January 2017 to December 2018, a total of 4,633 men tested in the HIVST model, and 1,780 men tested in the HIV-RDT model. The total number of new diagnosis was 155 for HIVST and 126 for the HIV-RDT model; the HIV test positivity was 3.3% (95% confidence interval (CI): 2.8-3.9) for the HIVST model and 7.1% (95% CI: 5.9-8.4) for the HIV-RDT model. The mean cost per person tested was $14.57 for HIVST and $24.74 for HIV-RDT. However, the mean cost per diagnosed was higher for HIVST ($435.52) compared with $349.44 for HIV-RDT.Conclusion: Our study confirms that compared to facility-based HIV-RDT, a community-based organization led HIVST program could have a cheaper mean cost per MSM tested for HIV in China. Better targeting of high-risk individuals would further improve the cost-effectiveness of HIVST.

Authors: Jiang Tongchao , Li Nan , Sun Haishuang , Jiang Tongcui
Published: December 2020

Background: This study aimed to compare the use of radiotherapy (RT) in gastric cancer (GC) patients from the SEER database and established a nomogram to assess cancer-specific survival (CSS).Methods: Patients from the SEER database between 2004 and 2013 were analyzed. Survival was analyzed by Kaplan-Meier curves and log-rank test. Prognostic factors in multivariate Cox analysis were screened to construct a nomogram. The performance the nomogram was validated via concordance index (C-index), calibration plots, and decision curve analyses (DCAs). Results: 9653 GC patients were analyzed totally. In the entire cohort, patients who received pre/postoperative RT had better survival than those who did not receive RT (P = 0.043 and < 0.001, respectively). Similar results were observed in lymph node-positive patients. However, no significant survival benefit was seen in lymph node-negative patients between postoperative RT group and no RT group (P = 0.057), but patients who received postoperative RT and those who did not receive RT experienced better survival than those who received preoperative RT (P < 0.001 and 0.001, respectively). Prognostic factors of GC analyzed by Cox regression model included age, race, tumor grade, tumor histology type, primary tumor site, T stage, lymph node metastasis ratio, RT status, and chemotherapy information independently (P < 0.001). The nomogram was established and showed excellent prediction performance, and its C-index of 0.725 were significantly higher than those of nomograms based AJCC system with C-index at 0.643. In addition, the calibration plots performed good consistency between the predicted and actual survival probabilities, and the DCAs indicated better clinical net benefits than the traditional AJCC system.Conclusions: RT can improve CSS in GC patients, especially those with positive lymph nodes. The construction and verification of a nomogram based on SEER database can effectively predict the survival outcomes of GC patients.

Background: Leishmania major and Leishmania tropica cause cutaneous leishmaniasis in humans and dogs in several parts of the world, with a large number of cases recorded in the Middle East. However, when they occur in sympatry, the role of each species of Leishmania in the epidemiology of cutaneous leishmaniasis (CL) is not clear. Methods: To determine the frequency of occurrence and to identify the species of Leishmania that infect humans and stray dogs in Riyadh and Al-Qaseem (Saudi Arabia), 311 stray dogs and 27 human patients who were suspected for Leishmania were examined for CL by a nested polymerase chain reaction (nPCR).Results: The use of nPCR detected seven patients (25.9%) who were positive for cutaneous leishmaniasis. Five patients from Riyadh were infected by L. major and two from Al-Qaseem by L. tropica. In addition, five dogs (1.6%) were infected by L. tropica. Conclusions: This is one of the first molecular studies of leishmaniasis to be conducted in Saudi Arabia. The relationship between the sand-fly vectors and the reservoirs of both Leishmania spp. is still scarcely known in this region, and epidemiological investigations are required in order to progress towards control and prevention of the infection in canine and human populations.

Background: Beta-ketothiolase deficiency (BKTD) is an autosomal recessive disorder caused by biallelic mutations in ACAT1 that affects both isoleucine catabolism and ketolysis. Scant information is available regarding the incidence, newborn screening (NBS), and mutational spectrum in China.Methods: We collected NBS, biochemical, clinical, and ACAT1 mutation data from 18 provinces or municipalities in China between January 2009 and May 2020, and systematically assessed all available published Chinese BKTD patients data.Results: Totally 16,088,190 newborns were screened and 14 were identified through NBS, with an estimated incidence of 1 per 1 million newborns in China. Twenty-nine patients were genetically diagnosed as BKTD and 12 patients were newly identified. Most patients showed typical blood acylcarnitine and urinary organic acid profiles. In particular, almost all patients (15/16, 94%) showed elevated C4OH levels. Eighteen patients presented acute metabolic decompensations and displayed variable clinical symptoms. The acute episodes of 9 patients were triggered by infections, diarrhea, and vaccination. About two thirds of patients have favorable outcomes, one showed developmental delay, while three had died. Twenty-seven distinct variants were identified in ACAT1, among which 5 were found to be novel.Conclusion: This study presented the largest series of BKTD cohort in China. Our results indicated that C4OH is a useful marker for the detection of BKTD. The performance of BKTD NBS could be improved by adding C4OH to the current panel of C5OH and C5:1 markers in NBS. The mutational spectrum and molecular profiles of ACAT1 in Chinese population were expanded with 5 newly identified variants.
The Burden of Pharmacological Treatment on Health-Related Quality of Life in People with a Urea Cycle Disorder – A Qualitative Study
Authors: Yeowell Gillian , Burns Danielle , Fatoye Francis
Published: December 2020

Background Urea cycle disorders (UCD) are a group of conditions of inborn errors of metabolism, typically presenting neonatally. Excess ammonia builds rapidly within the body, risking hyperammonemic episodes and potentially death. Long-term management of the condition includes restrictive protein consumption, pharmacological interventions and, in extreme cases, liver transplantation. Pharmacological treatments such as sodium benzoate and sodium phenylbuturate have proven effective but not without a multitude of negative attributes including poor taste, elevated volume and associated gastrointestinal discomfort that impacts on health-related quality of life. Glycerol phenylbutyrate (GPB) has recently become a widely available pharmacological treatment with early reports of improved qualities. The following study aims to explore the burden of pharmacological treatment on health-related quality of life in people with a UCD. Results 9 carers of people living with a UCD were interviewed regarding their experiences of pharmacological treatment in relation to their, and their dependent’s health-related quality of life after transitioning to GPB. Three main themes were identified following data analysis: psychological health, physical health and social participation. Carers struggled with anxiety surrounding their dependent’s condition and the relentless battle of administering medication. Medication administration was perceived to have improved since the transition to GPB, alleviating distress for both carer and dependent. Issues involving schooling were commonly described, ranging from difficulties integrating their dependent into mainstream schooling and the impact of treatment on participation in school and extracurricular activities. Based upon participant’s experiences, it could be suggested that some burden had been relieved by the transition to GPB. However, it appeared that the burden would persist despite treatment, owing to the continuing nature of the condition. Conclusions Adhering to a strict pharmacological regime caused immense stress for both carers and dependents, severely impacting on typical social activities such as eating at a restaurant or going on holiday. GPB was perceived to have alleviated some burden in terms of administration. Practitioners should consider these findings when making clinical decisions for UCD patients and the effect of pharmacological treatment on health-related quality of life. Emotional support resources should be made readily available to families to assist with daily living.

Published: December 2020

BackgroundThe Cascades Region, Burkina Faso, has a high malaria burden despite reported high insecticide-treated mosquito net (ITN) use. Human and vector activities outside the hours when indoor interventions offer direct protection from infectious bites potentially increase exposure risk to bites from malaria-transmitting Anopheles mosquitoes. This work investigated the degree of variation in human behaviour both between individuals and through time (season) to quantify how it impacts exposure to malaria vectors.MethodsPatterns in human overnight activity (18:00-06:00) to quantify time spent using an ITN across 7 successive nights in two rural communities, Niakore (N = 24 participants) and Toma (71 participants), were observed in the dry and rainy seasons, between 2017-2018. Hourly human landing Anopheles mosquito catches were conducted in Niakore specifically, and Cascades Region generally, between 2016-2017. Data were statistically combined to estimate seasonal variation in time spent outdoors and Anopheles bites received per person per night (bpppn).ResultsSubstantial variability in exposure to outdoor Anopheles bites was detected within and between communities across seasons. In October, when Anopheles densities are highest, an individual’s risk of Anopheles bites ranged from 2.2 to 52.2 bites per person per night (bpppn) within the same week with variable risk dependent on hours spent indoors. Comparably higher outdoor human activity was observed in April and July but, due to lower Anopheles densities estimated, bpppn were 0.2 – 4.7 and 0.5 – 32.0, respectively. Males and people aged over 21 years were predicted to receive more bites in both sentinel villages.ConclusionThis work presents one of the first clear descriptions of the degree of heterogeneity in time spent outdoors between people and across the year. Appreciation of sociodemographic, cultural and entomological activities will help refine approaches to vector control.

Authors: Jentsch Holger F.R. , Flechsig Christian , Kette Benjamin , Eick Sigrun
Published: December 2020

Background: This study was aimed to investigate if the adjunctive use of erythritol air-polishing powder applied with the nozzle-system during subgingival instrumentation (SI) has an effect on the outcome of non-surgical periodontal treatment in patients with moderate to severe periodontitis. Methods: Fourty-two individuals with periodontitis received nonsurgical periodontal therapy by SI without (controls, n=21) and with adjunctive air-polishing using nozzle + erythritol powder (test, n=21). They were analyzed for the clinical variables BOP (primary outcome at six month), probing depth (PD), attachment level (AL), four selected microorganisms and two biomarkers at baseline, before SI as well as three and six months after SI. Statistical analysis included nonparametric tests for intra- and intergroup comparisons. Results: In both groups, the clinical variables probing depth (PD), attachment level and BOP significantly improved three and six months after SI. The number of sites with PD ≥ 5mm was significantly lower in the test group than in the control group after six months. At six months vs. baseline, there were significant reductions of Tannerella forsythia and Treponema denticola counts as well as lower levels of MMP-8 in the test group. Conclusions: Subgingival instrumentation with adjunctive erythritol air-polishing powder does not reduce BOP. But it may add beneficial effects like reducing the probing depth measured as number of residual periodontal pocket with PD ≥ 5mm when compared with subgingival instrumentation only. Clinical relevance: The adjunctive use of erythritol air-polishing powder applied with the nozzle-system during SI may improve the clinical outcome of SI and may reduce the need for periodontal surgery. Trial registration: The study was retrospectively registered in the German register of clinical trials, DRKS00015239 on 6th August 2018, https://www.drks.de/drks_web/navigate.do?navigationId =trial.HTML&TRIAL
A GPU based multidimensional amplitude analysis to search for tetraquark candidates
Authors: Sur Nairit , Cristella Leonardo , Florio Adriano Di , Mastrapasqua Vincenzo
Published: December 2020

The demand for computational resources is steadily increasing in experimental high energy physics as the current collider experiments continue to accumulate huge amounts of data and physicists indulge in more complex and ambitious analysis strategies. This is especially true in the fields of hadron spectroscopy and flavour physics where the analyses often depend on complex multidimensional unbinned maximum-likelihood fits, with several dozens of free parameters, with an aim to study the internal structure of hadrons.
Graphics processing units (GPUs) represent one of the most sophisticated and versatile parallel computing architectures that are becoming popular toolkits for high energy physicists to meet their computational demands. GooFit is an upcoming open-source tool interfacing ROOT/RooFit to the CUDA platform on NVIDIA GPUs that acts as a bridge between the MINUIT minimization algorithm and a parallel processor, allowing probability density functions to be estimated on multiple cores simultaneously.
In this article, a full-fledged amplitude analysis framework developed using GooFit is tested for its speed and reliability. The four-dimensional fitter framework, one of the firsts of its kind to be built on GooFit, is geared towards the search for exotic tetraquark states in the [[EQUATION]] decays and can also be seamlessly adapted for other similar analyses. The GooFit fitter, running on GPUs, shows a remarkable improvement in the computing speed compared to a ROOT/RooFit implementation of the same analysis running on multi-core CPU clusters. Furthermore, it shows sensitivity to components with small contributions to the overall fit. It has the potential to be a powerful tool for sensitive and computationally intensive physics analyses.

Published: December 2020

The problem of improving the quality of state and municipal finance management is very urgent at the present time. The purpose of the study is an attempt to substantiate the need to improve the methodology for assessing the quality of municipal finance management. One of the tasks is to test the hypothesis: municipalities with the population involved in the processes of initiative budgeting are most efficient in managing municipal finances. The object of the study is the municipalities of the Transbaikal region. In the course of the study, an analysis of the regional legal acts concerning the assessment of the quality of municipal finance management was carried out, as well as an analysis of this assessment in the context of some municipalities (urban districts) of the Transbaikal region. The analysis showed that the methodology for assessing the quality of municipal finance management in the constituent entities of the Russian Federation is based on indicators characterizing the state of municipal finance and does not fully cover indicators of the quality of local authorities’ management decisions. The analysis also revealed a correlation relationship between the financial management quality of the municipal entity of the Transbaikal region and the degree of population involvement in the budget process. The article concludes that it is necessary to improve the existing methodology for assessing the quality of municipal finance management. The method based on 3 groups of indicators - the state of municipal finances, the level of municipal programs (national projects) implementation, the quality of municipal finance management is proposed. In order to improve financial discipline and transparency of the budgetary process, the author proposes to introduce a pilot project to develop initiative budgeting in municipalities

The specificity of the territory of the upper Amur basin is shown, which consists in a significant variety and complexity of natural complexes. The object of the study was the Onon river, the subject-riverbed processes that occur in the territory under the influence of natural factors. The purpose of the study is to identify, analyze and evaluate the scale of development of riverbed processes in the upper Amur basin. The tasks were to identify active areas of water erosion. Onon, spatial analysis of the received information, identification of the dynamics and intensity of riverbed processes in active areas during the destructive leash of 2018 and beyond. The relevance of the work has been determined by the need to quickly identify and prevent the development of riverbed processes for erosion control and rational use of land resources for further industrial use. The research methods used are analysis and interpretation of high-resolution satellite images and other multi-time cartographic materials, processing and digitization of images. The main natural channel-forming factors of the Onon river that determine the current dynamics of channel deformations are identified and analyzed. The theoretical and practical significance of the study is to determine the degree of influence on riverbed processes of various riverbed-forming natural factors. The necessity of carrying out measures on the territory of the upper Amur basin to solve water management problems is justified

Change of species set and abundance along a short time gradient: The impact of weather conditions on the conservation of butterflies.
Authors: Brunzel Stefan , Elligsen Henning
Published: December 2020

In einer artenarmen Region im Märkischen Sauerland (Nordrhein-Westfalen) wurde 1989-1991 eine rasterfeldbezogene Dauerbeobachtung von Tagfaltern begonnen und 1997 wiederholt. Gegenüber 1989-1991 zeigten sich 1997 Unterschiede im Artenset und der Abundanz einiger Arten. In Übereinstimmung mit anderen Untersuchungen wird diesbezüglich der Einfluß von Witterungsbedingungen diskutiert.
In einem Betrachtungszeitraum von 1987 bis 1995 sind die Witterungsbedingungen im Untersuchungsgebiet seit 1989 günstiger geworden. Die mittleren Monatstemperaturen und die monatliche Sonnenscheindauer sind vor allem zwischen 1989 und 1992 deutlich angestiegen, während die monatliche Niederschlagssumme stark abgenommen hat. Dieser Anstieg war sowohl während der hauptsächlichen Falterflugzeit (April bis September) als auch von Oktober bis März (möglicherweise für Präimaginalstadien relevant) festzustellen. - Einige vergleichsweise xerothermophile Arten konnten 1997 erstmals nachgewiesen werden. Andere, während der letzten 30 Jahre verschwundene Arten, wurden wiedergefunden. Mehrere Arten mit individuenarmen Vorkommen während der Erfassungen 1989-1991 besaßen 1997 eine größere Zahl und individuenstärkere Vorkommen, obwohl sich weder die Landschaftsstrukturen noch die Habitatbedingungen im Untersuchungsgebiet wesentlich geändert haben. Witterungsbedingungen werden hierfür als Ursache diskutiert und mit möglichen Auswirkungen von Habitatmanagement verglichen.StichwörterButterfly monitoring, species set, impact of weather conditions, Germany, nature conservation.

Species-specific foraging strategies of the syntopical and synchronous bees Panurgus calcaratus (Scopoli, 1763) and Dasypoda hirtipes (Fabricius, 1793) (Hymenoptera: Apidae).
Authors: Levermann Eva-Maria , Bischoff Inge , Wagner Thomas
Published: December 2020

Die Sammelstrategie der beiden endogäischen, oligolektischen syntop und synchron auftretenden Wildbienenarten Panurgus calcaratus (Scopoli, 1763) und Dasypoda hirtipes (Fabricius, 1793) wurden im Naturschutzgebiet Wahner Heide (Rheinland, BRD) untersucht. Saisonale und diurnale Rhythmik sowie die Sammelstrategien beider Arten wurden erfaßt, um eventuell bestehende Trennungsmechanismen oder Nischendiffenzierung aufzudecken. Neben dem Verproviantierungsverhalten der Bienen wurde die Oligolektie durch Pollenentnahme von Weibchen und durch Beobachtung an den Pollenquellen überprüft. Beide Arten nutzen ausschließlich gelbe, photonastische, zungenblütige Asteraceae als Pollenquellen, präferieren sandige Flächen mit geringer Vegetation als Nistplatz und sind von Anfang Juli bis Ende August aktiv. Eine Spezialisierung innerhalb der Oligolektie auf einzelne Arten zungenblütiger Asteraceae konnte nicht erkannt werden. Dasypoda hirtipes wies eine allgemein längere diurnale Aktivität auf und war zudem auch bei geringeren Temperaturen noch aktiv. Die Pollensammelaktivitäten werden bei beiden Arten maßgeblich von den photonastischen Pollenquellen limitiert. Desweiteren ist die Bienenaktivität von klimatischen Faktoren wie Lichtintensität, Bewölkung und Lufttemperatur abhängig. Artspezifische diurnale und saisonale Verhaltensweisen und Aktivitätsrhythmen werden im Hinblick auf Körpergröße und -farbe, Hitzeabsorptions- und Reflektions-Fähigkeit, Überhitzungsgefahr sowie Effekte der Ekto- und Heterothermie auf den Wärmehaushalt diskutiert. Jede Art verfolgt eine eigene Sammelstrategie, welche hauptsächlich durch ultimative Faktoren wie die Physiologie der jeweiligen Bienenart beeinflußt und zugleich limitiert wird. Weder Nistplatzangebot noch die Ressourcen Pollen oder Nektar sind im Untersuchungsgebiet begrenzt, so daß keine Evidenz für Konkurrenz zwischen den beiden Arten besteht.StichwörterInterspecific competition, oligolecty, optimal foraging strategies, photonasty, resource partitioning, separation mechanisms.
Beiträge zur Collembolenfauna der Höhlen deutscher Mittelgebirge Teil II (mit Anhang über einige Dipluren).
Authors: Palissa Alfred
Published: December 2020

Das Untersuchungmaterial (über 30000 Collembolen) wurde in den Jahren 1988-1991 aus 102 Höhlen deutscher Mittelgebirge (Harz, Thüringer Bergland, Kyffhäuser und Zittauer Gebirge) vorwiegend über Barber-Fallen gesammelt. Die Collembolen konnten 82 Arten zugeordnet werden, einige Tiere waren nur bis zur Gattung bestimmbar.
Die Anzahl der in den untersuchten Gebieten auftretenden Arten war sehr unterschiedlich: MH=32, SH=52, Thü=42, Ky=31; Zi=20, was aber z. T. durch die unterschiedliche Intensität der Aufsammlungen in den Höhlen bedingt ist. 32 Arten, das sind etwa 40%, waren gebietsspezifisch. Der relative Anteil gebietsspezifischer Arten war mit 30% im Zittauer Gebirge am höchsten. - Eine Art, Arrhopalites troglophilus erwies sich als neu für die Wissenschaft. - Die vorkommenden Collembolenarten werden vorgestellt unter Bezug auf faunistische, taxonomische und ökologische Fragen. - Das untersuchte Material enthält 10 Arten (einschließlich der von Schulz, 1994 vorab publizierten), die in Deutschland bisher nicht bekannt waren. Das sind Schaefferia sexoculata, Paranura sexpunctata, Neanura longiseta, Onychiurus schoetti, Onychiurus heterodoxus, Cryptopygus garretti, Isotoma tigrina, Orchesella longifasciata, Arrhopalites boneti, Arrhopalites troglophilus. - Erstmals in Höhlen aufgefunden wurden 24 Arten (ebenfalls einschließlich der bereits vorab publizierten): Hypogastrura burkilli, Willemia intermedia, Xenyllodes armatus, Paranura sexpunctata, Pseudachorutes asigillata, Pseudachorutes corticicola, Pseudachorutes subcrassus, Neanura conjuncta, Onychiurus absoloni, Onychiurus heterodoxus, Onychiurus vanderdrifti, Onychiurus sublegans, Folsomia manolachei, Folsomia penicula, Isotoma fennica, Isotoma neglecta, Isotoma tigrina, Entomobrya marginata, Lepidocyrtus nigrescens, Orchesella longifasciata, Arrhopalites principalis, Arrhopalites troglophilus, Sminthurinus niger, Dicyrtoma minuta.
Für die in den Höhlen mitteldeutscher Gebirge auftretenden Schaefferia-Arten wird ein aktuelles Verbreitungsbild vorgestellt. - Tetrodontophora bielanensis wird erstmals aus dem Kyffhäuser nachgewiesen, weit ab vom bisher bekannten Verbreitungsgebiet.StichwörterCollembola, Diplura, Faunistics, Taxonomy, German highlands.Nomenklatorische Handlungentroglophilus Palissa, 2000 (Arrhopalites), spec. n.
