Cím:Comparative Phytotoxicity of Metallic Elements on Duckweed Lemna gibba L. Using Growth- and Chlorophyll Fluorescence Induction-Based Endpoints / Muhammad Irfan, Ilona Mészáros, Sándor Szabó, Viktor Oláh
Dátum:2024
ISSN:2223-7747
Megjegyzések:In this study, we exposed a commonly used duckweed species-Lemna gibba L.-to twelve environmentally relevant metals and metalloids under laboratory conditions. The phytotoxic effects were evaluated in a multi-well-plate-based experimental setup by means of the chlorophyll fluorescence imaging method. This technique allowed the simultaneous measuring of the growth and photosynthetic parameters in the same samples. The inhibition of relative growth rates (based on frond number and area) and photochemical efficiency (F-v/F-o and Y(II)) were both calculated from the obtained chlorophyll fluorescence images. In the applied test system, growth-inhibition-based phytotoxicity endpoints proved to be more sensitive than chlorophyll-fluorescence-based ones. Frond area growth inhibition was the most responsive parameter with a median EC50 of 1.75 mg L-1, while F-v/F-o, the more responsive chlorophyll-fluorescence-based endpoint, resulted in a 5.34 mg L-1 median EC50 for the tested metals. Ag (EC50 0.005-1.27 mg L-1), Hg (EC50 0.24-4.87 mg L-1) and Cu (EC50 0.37-1.86 mg L-1) were the most toxic elements among the tested ones, while As(V) (EC50 47.15-132.18 mg L-1), Cr(III) (EC50 6.22-19.92 mg L-1), Se(VI) (EC50 1.73-10.39 mg L-1) and Zn (EC50 3.88-350.56 mg L-1) were the least toxic ones. The results highlighted that multi-well-plate-based duckweed phytotoxicity assays may reduce space, time and sample volume requirements compared to the standard duckweed growth inhibition tests. These benefits, however, come with lowered test sensitivity. Our multi-well-plate-based test setup resulted in considerably higher median EC50 (3.21 mg L-1) for frond-number-based growth inhibition than the 0.683 mg L-1 median EC50 derived from corresponding data from the literature with standardized Lemna-tests. Under strong acute phytotoxicity, frond parts with impaired photochemical functionality may become undetectable by chlorophyll fluorometers. Consequently, the plant parts that are still detectable display a virtually higher average photosynthetic performance, leading to an underestimation of phytotoxicity. Nevertheless, multi-well-plate-based duckweed phytotoxicity assays, combined with chlorophyll fluorescence imaging, offer definite advantages in the rapid screening of large sample series or multiple species/clones. As chlorophyll fluorescence images provide information both on the photochemical performance of the test plants and their morphology, a joint analysis of the two endpoint groups is recommended in multi-well-plate-based duckweed phytotoxicity assays to maximize the information gained from the tests.

Cím:The draft genome of Spiraea crenata L. (Rosaceae) : the frst complete genome in tribe Spiraeeae / Levente Laczkó, Sándor Jordán, Szilárd Póliska, Hanna Viktória Rácz, Nikoletta Andrea Nagy, Attila Molnár V., Gábor Sramkó
Dátum:2024
ISSN:2052-4463
Megjegyzések:Spiraea crenata L. is a deciduous shrub distributed across the Eurasian steppe zone. The species is of cultural and horticultural importance and occurs in scattered populations throughout its westernmost range. Currently, there is no genomic information on the tribe of Spiraeeae. Therefore we sequenced and assembled the whole genome of S. crenata using second- and third-generation sequencing and a hybrid assembly approach to expand genomic resources for conservation and support research on this horticulturally important lineage. In addition to the organellar genomes (the plastome and the mitochondrion), we present the first draft genome of the species with an estimated size of 220 Mbp, an N50 value of 7.7 Mbp, and a BUSCO score of 96.0%. Being the first complete genome in tribe Spiraeeae, this may not only be the first step in the genomic study of a rare plant but also a contribution to genomic resources supporting the study of biodiversity and evolutionary history of Rosaceae.

Megjegyzések:The dispersal of fish into distant and isolated habitats remains a topic of continuous discussion in the field of fish biogeography. This is particularly relevant due to the perceived limitation of fish movement to what is known as active dispersal. Fish migration is often confined to interconnected water bodies, underscoring the significance of dispersal for fish inhabiting isolated aquatic habitats. However, empirical evidence for a natural (i.e. not human-mediated) mechanism has been limited. Here we explore and provide evidence for waterbird-mediated endozoochory as a possible dispersal mechanism in various fish species and families. We force-fed mallards Anas plathyrynchos with fertilised eggs of nine bony fish species, covering nine taxonomic families. We recovered viable embryos of five fish taxa in the faeces of mallard, proving the ability of fish eggs to survive the passing of the digestive system of waterbirds. Moreover, the recovered eggs successfully hatched into larvae in two fish species. Taking into the flight speed and numerosity of mallards, as well as the high abundance of fish eggs, our results highlight endozoochory of fish eggs by waterbirds as a possible significant, although likely rare natural dispersal mechanism that can occur across more species than previously known in freshwater fish.

Cím:The ecological footprint of outdoor activities: Factors affecting human-vectored seed dispersal on clothing / Katalin Lukács,Ágnes Tóth, Réka Kiss, Balázs Deák, Zoltán Rádai,Katalin Tóth, András Kelemen, Zoltán Bátori, Alida Anna Hábenczyus,Csaba Tölgyesi,Tamás Miglécz, Laura Godó, Orsolya Valkó

Megjegyzések:In the Anthropocene, humans are among the most abundant long-distance seed dispersal vectors globally, due to our increasing mobility and the growing global population. However, there are several knowledge gaps related to the process of human-vectored dispersal (HVD) on clothing. In a multi-site field experiment covering various habitat types in three countries of Central-Europe, we involved 88 volunteer participants and collected 251 HVD samples and 2008 subsamples from their socks and shoes. We analysed the number of diaspores and species in the samples. Specifically, we studied the effects of site characteristics (variables related to habitat types and season), vector characteristics (activity type, gender, clothing type, shoe type) and plant characteristics (species pool of the visited habitats and plant traits) on the number of diaspores and array of species dispersed. We assessed the habits of people that could be relevant for HVD with a questionnaire survey. A total of 35,935 diaspores of 229 plant taxa were identified from the samples, which indicates a huge potential of HVD in dispersing diaspores across habitats and regions. Most diaspores were recorded in grassland habitats, and more diaspores were dispersed during fieldwork than excursions. Clothing type also played a decisive role: there were more diaspores and species when wearing short-top shoes and short trousers than long ones. Even though our study was carried out mainly in natural or semi-natural habitats, a large number of dispersed species were disturbance-tolerants and weeds and only a few were specialists, suggesting the controversial role of HVD in conservation. At the individual level, people can reduce the number of diaspores through their clothing choices and diaspore removal habits, while providing adequate equipment for staff, operating cleaning stations, and increasing awareness of employees are main ways in which unintended diaspore dispersal can be tackled at the institutional level.

Cím:Tracking abandoned, lost or discarded fishing gears of anglers by analyzing magnet fishers' catch / Zsolt Neményi, András Nagy, Attila Hagyó, Jenő Nagy, Zoltán Vitál, Balázs András Lukács, Viktor Löki
Dátum:2024
ISSN:0018-8158 1573-5117
Megjegyzések:Abandoned, lost, or discarded fishing gears (ALDFG) are major pollutants in water ecosystems, however, there is a serious lack of estimates on the loss of recreational fishing gears worldwide. To fill this gap, some recreationists like magnet fishers, who use neodymium magnets to retrieve metal items from water, can provide additional information. As they often remove ALDFG, we aimed to carry out the first social media analysis of their online content by searching ALDFG in their posts. During our work, we analyzed Hungarian magnet fishers' posts, covering a total of 6 years from their initial activities on social media. In total, 2,889 posts were scanned of which 1,039 photos and 84 videos were analyzed. Magnet fishers caught 2,018 fishing gears while a total of 31 types of fishing gear were identified. Significant differences were found between flowing (n=1,959, mean ± SD = 12.89 ± 16.51) and standing waters (n=889, mean±SD?=?24.69±31.39) in the numbers of fishing gears. Based on the results, we can conclude that ALDFG is a common freshwater pollutant in the country, and social media activities of magnet fishers can be used in detecting freshwater ALDFG containing metal.

Cím:Changes of the composition of the Noctuoidea fauna along a geographical gradient in the northeastern part of the Carpathian Lowland / Szabolcs Szanyi, Kálmán Szanyi, Antal Nagy
Dátum:2024
ISSN:2676-8615 2676-8607
Megjegyzések:The northeastern part of the Carpathian Lowland is one of the most species-rich parts of the region, despite the long-term and sometimes extreme changes in land use. The fragmented remains of formerly contiguous forests maintain a significant part of the wildlife living in different oak, mixed oak, and gallery forest, and even faunas of connected grassland habitats. To reveal how the parallel Carpathian and Pannonian effects form the local insect fauna, the Noctuoidea assemblages of eight forest patches were assessed and compared, based on the distribution data of 479 species. Three types of assemblages were designated, with similar diversity but different compositions. The most unique and valuable ones can be found in the colline area of Transcarpathia, where the high habitat diversity supported by the topography promotes the coexistence of the species of humid forest fauna and many steppic and southern elements. The protection and planned management of these remained forest patches and their network in international cooperation can maintain a significant part of the fauna of the affected regions.
