Bacterial and Archaeal Communities Change With Intensity of Vegetation Coverage in Arenized Soils From the Pampa Biome
2019
Arenization occurs in regions that present sandy soils with normal rainfall levels. Predatory use of environmental sources, the dissolution of arenitic rocks and reworking of non-consolidated surface sands intensify this degradation scenario. Thus, this work aimed to evaluate the impact of the arenization process in the Brazilian Pampa Biome and how this phenomenon affects the soil microbial and plant communities. For this purpose, three arenized areas in Southern Brazil (Pampa Biome) were selected and, in each one, three sampling points were studied: arenized (ARA), arenized to grassland transition (AGT), and grassland (GRA) areas. In the three sampling points, soils presented low levels o…
Growth and Physiological Performance of a Coastal Species Trifolium fragiferum as Affected by a Coexistence with Trifolium repens, NaCl Treatment and…
2021
The aim of the present study was to analyze the growth and physiological performance of two coexisting species, Trifolium fragiferum, and Trifolium repens, under the effect of NaCl and rhizobial symbiosis. Seeds of T. fragiferum and T. repens were collected from populations in the wild, and plants were cultivated in an automated greenhouse, two plants per container. Three basic types of planting were performed: (1) both plants were T. fragiferum (single species), (2) one T. fragiferum and one T. repens (species coexistence), (3) both plants were T. repens (single species). For every basic type, three subtypes were made: (1) non-inoculated, (2) inoculated with rhizobia taken from T. fargifer…
Zoonotic Dirofilaria immitis and Dirofilaria repens infection in humans and an integrative approach to the diagnosis
2021
Abstract Dirofilariosis by Dirofilaria immitis and Dirofilaria repens is endemic in dogs from countries of the Mediterranean basin. Both species may infect humans, with most of the infected patients remaining asymptomatic. Based on the recent description of the southernmost hyperendemic European focus of heartworm disease in dogs from the Pelagie archipelagos, we performed a serological and molecular survey in human population of that area. Human blood samples were collected in the islands of Linosa (n=101) and Lampedusa (n=296) and tested by ELISA and molecular test for the detection of D. immitis and D. repens. Samples were also screened for filarioid-associated endosymbionts, Wolbachia s…
Ložņu āboliņa (Trifolium repens L.) Eiropas populāciju ģenētiskās daudzveidības salīdzinājums
2021
Ložņu āboliņam ir plašs izplatības areāls – no arktiskiem reģioniem līdz augstkalnu (6000 m) reģioniem. Tas ir plaši izplatīts arī vietās ar augstu vides piesārņojuma līmeni. Maģistra darba mērķis ir noteikt ložņu āboliņa Eiropas populāciju ģenētisko daudzveidību atkarībā no dažādiem augšanas apstākļiem. Ģenētiskās daudzveidības noteikšanai tika izmantota iPBS metode un izstrādāta metode UV-B starojuma izraisītas retrotranspozonu pārvietošanās noteikšanai. Rezultāti liecina, ka analizētā Eiropas populācija iedalās divos lielos klāsteros, atsevišķi izdaloties augstkalnu apgabalam. Secināts, ka augstkalnu reģionos izplatītās populācijas ģenētiski ir atšķirīgas no zemienēs izplatītājām. Analiz…
Does plant growth phase determine the response of plants and soil organisms to defoliation?
2005
Abstract To test a hypothesis that the effects of defoliation on plant ecophysiology and soil organisms depend on the timing of defoliation within a growing season, we established a greenhouse experiment using replicated grassland microcosms. Each microcosms was composed of three plant species, Trifolium repens , Plantago lanceolata and Phleum pratense , growing in grassland soil with a diverse soil community. The experiment consisted of two treatment factors—defoliation and plant growth phase (PGP)—in a fully factorial design. Defoliation had two categories, i.e. no trimming or trimming a total of four times at 2 week intervals. The PGP treatment had four categories, i.e. 1, 3, 7 or 13 wee…

New Triterpenoidal Saponins fromGypsophila repens
2007
Six new triterpene glycosides, repensosides A–F (1–6, resp.), were isolated from the roots of Gypsophila repens L. Their structures, established by extensive 1D- and 2D-NMR spectroscopic experiments as well as MS analyses, were found to be based on gypsogenic acid (or gypsogenin) as aglycone, with three to nine branched or unbranched sugar moieties.

Ložņu āboliņa (Trifolium repens L.) Karpatu kalnu un Latvijas populāciju ģenētiskās daudzveidības salīdzinājums
2019
Sandra Dombrovska (2019): Ložņu āboliņa (Trifolium repens L.) Karpatu kalnu un Latvijas populāciju ģenētiskās daudzveidības salīdzinājums. Ložņu āboliņš (Trifolium repens L.) ir viens no plaši izmantotajiem lopbarības augiem visā pasaulē. Izmantots kā modeļobjekts. Bakalaura darba mērķis ir salīdzināt Karpatu kalnu savvaļas populāciju un šķirnes “Daile” materiālu daudzveidību un retrotranspozonu kustību pēc UV gaismas stresora ietekmes. Bakalaura darba izstrādes laikā tika izdalīts DNS no 117 izkaltētiem paraugiem. Tika veikta iPBS analīze, klasteru analīze, UV-B starojuma ietekmes analīze. Rezultāti liecina, ka šķirnes "Daile" populācija iedalās divās atsevišķās grupās un Slovākijas genoti…
