Field application of the juvenile hormone analogue fenoxycarb against hopper bands of Locusta migratoria capito in Madagascar
1997
Summary Field trials have been carried out to examine the suitability of the JHA fenoxycarb in locust control. Laboratory tests have shown that a variety of JHAs, including fenoxycarb, applied to last instar larvae increased mortality, induced morphogenetic defects during metamorphosis, reduced fertility and provoked solitarisation of gregarious hoppers. The phase shift was indicated by green coloration and the acquisition of morphological and behavioural characteristics typical for solitary locusts. The present field experiments should clarify whether or not the effects observed in the laboratory are also observed with hopper bands in their natural habitat and if swarm formation and emigra…
Model społeczeństwa a założenia Specjalnej Strefy Demograficznej
2016
Założenia opolskiej Specjalnej Strefy Demograficznej odwołują się do strukturalno-systemowych teorii społeczeństwa. Stan katastrofy demograficznej wymaga, moim zdaniem, przeprowadzenia reprezentatywnych badań empirycznych wśród młodego pokolenia, opracowania socjologicznego studium i uzupełnienia teoretycznych założeń Specjalnej Strefy Demograficznej w regionie opolskim.
Effects of Oral Supplementation with Myo-Inositol and D-Chiro-Inositol on Ovarian Functions in Female Long-Term Survivors of Lymphoma: Results from a…
2022
The progressive improvement of lymphoma treatment has led to an important prolongation of patient survival and life expectancy. The principal international scientific societies of oncology now therefore recommend that long-term survivors of lymphoma join fertility programs. Specifically, fertile-age patients should be assisted by a multidisciplinary team, including specialists dedicated to fertility preservation in oncology, in order to support the completion of their reproductive project. In the general population, the use of Myo-Inositol and D-Chiro-Inositol (MI/DCI) has been demonstrated to be an effective choice to treat ovarian dysfunctions, with a consequent improvement in reproductiv…
Is it possible to understand a book missing a quarter of the letters? Unveiling the belowground species richness of grasslands
2022
Abstract Knowledge of species richness patterns in plant communities is biased toward its hidden belowground part and is derived only from the part visible aboveground. Studies on the relationship of the above- to belowground parts of plant communities suffer from the lack of a consistent and uniform approach to assess their taxonomic composition, particularly in species-rich ecosystems. This study described the proportion between above- and belowground parts of vegetation in three grassland types along with the environmental factors that affect them, using eDNA metabarcoding and an observer survey. The internal transcribed spacer 2 (ITS2) region was used to analyze the total plant richness…
Role of land set-up systems on soil (physicochemical) conditions
2020
Land reclamation and drainage networks represent one of the most ancient human modifications of the Italian soilscape, where tailored land set-up systems were developed in agro- and forestecosystems in three millennia of man’s activity. Most of once manually maintained land settings are currently scarcely working or even disappeared because of the cost needed for their maintenance and the advent of mechanization that have simplified the field organization. The scarce attention to the soil experienced in the last decades, has accelerated soil erosion and flooding events, which entailed high costs in terms of money and human lives, but also caused reduction of soil thickness, water holding ca…
Shifting Long-Term Tillage to Geotextile Mulching for Weed Control Improves Soil Quality and Yield of Orange Orchards
2023
Weed control in urban and peri-urban orange orchards is challenging due to operational and legislative restrictions. Tillage, besides from negatively affecting soil fertility and microorganisms, is demanding for humans. On the other hand, herbicides are advised against due to the possibility to reach waterbodies from the soil surface. Therefore, in urban and peri-urban areas, instead of tillage and herbicides, mulching with black plastic geotextile fabric is often used. This study aimed at assessing the impact of long-term soil mulching with black plastic geotextile fabric on soil fertility, microbial community and yield of an orange orchard in comparison to conventional tillage. To this ai…
Czy "pułapka niskiej dzietności" w województwie opolskim? Perspektywa socjologiczna
2017
Badania społeczne prowadzone w krajach Unii Europejskiej, w tym w Polsce dowodzą, że rośnie popularność i znaczenie alternatywnych form życia rodzinnego i coraz mocniej ujawniają się niekorzystne zmiany demograficzne determinowane niechęcią młodych ludzi do posiadania większej liczby potomstwa lub w ogóle niechęcią do posiadania dzieci. W kraju ta sytuacja dotyczy przede wszystkim Opolszczyzny. Podtrzymuję zatem diagnozę dotyczącą przemian systemu wartości opolskiej młodzieży z 2007 r. i na podstawie wyników badań pilotażowych z 2014 r. formułuję uzupełniającą hipotezę, że być może mamy na Opolszczyźnie do czynienia z „pułapką niskiej dzietności” polegającą na ukształtowaniu nowych wzorców …
