Macaronesia, with the exception of Azores, is one few Palearctic provinces where basic taxonomic information on freshwater copepods still lacking. We redescribed Eucyclops azorensis, a cyclopid crustacean so far known only in and report occurrence this species Algeria Madeira Island. azorensis was formerly considered to be subspecies E. agiloides (East Africa); therefore, latter here as well based type non-type material. Morphological comparisons between other taxa (E. serrulatus roseus),...
Aquatic ecosystems are under pressure due to human activity. In the summer of 2022, Odra River (Central Europe) suffered a massive death fish and mollusks. This paper aims show selected water quality parameters before during ecological disaster find which may have been crucial development this disaster. We used Kruskal–Wallis test Spearman’s correlation check parameters’ spatial temporal diversification. addition, non-metric multidimensional scaling was performed. The system were analyzed in...
Abstract In a moss sample collected in Ribeiro Frio, Madeira, Paramacrobiotus gadabouti sp. nov. was found and described using the integrative taxonomy approach. The new species is based on morphological morphometric data from both phase-contrast light microscopy (PCM), as well scanning electron (SEM). Moreover, four DNA markers, three nuclear (18S rRNA, 28S ITS-2) one mitochondrial (COI) were used to elucidate phylogenetic position of within family Macrobiotidae. has microplacoid that...
Background: Secondary salinity of river water reduces the value ecosystem services, negatively impacting entire aquatic and reducing possibility use. In Poland, significant anthropogenic rivers reservoirs is usually associated with mining activity consisting pumping salty mine into settling ponds or often directly rivers. However, to assess reasons for Vistula waters, it necessary identify all sources salt in surface enabling assessment load waters. Methods: The paper presents four data...
Transformation of the river catchment and bed cause significant changes in functioning ecosystems. The main effects anthropogenic transformations are hydrological changes, such as lower current velocity or an increase nutrient content, higher temperature. Zooplankton reacts rapidly to new environmental conditions rivers, increasing its richness abundance. We tried answer two questions: what type use has a greater influence on zooplankton communities how do dam impoundments downstream? study...
The main aim of our research was to show that the body size planktonic cladoceran Daphnia cucullata can be used as an indicator ecological status lakes. We selected this species because it is one most common zooplankton in Europe and exhibits a high degree morphological variability depending on environmental conditions. Additionally, D. almost entirely ignored food source by fish unlike other species, often dominates lakes where predation intense. Therefore, we could minimize top-down...
Abstract This study aimed to achieve a better understanding of the features zooplankton assemblages in small water bodies and their biodiversity composition relation presence fish accompanying environmental characteristics. was conducted 16 mid-field ponds. Compositional indexes ordination methods were used analyze relationship between unstable fishless stable A total 121 taxa identified. indicators revealed significant differences ponds (FPs) (FLPs). Canonical correspondence analysis...
Water mites represent the group with highest degree of endemism among all macroinvertebrates living in freshwater habitats Madeira. The water mite fauna this archipelago has been well known for a long time, but until now they have not molecularly investigated. So far, 25 species recorded, most them endemic to library presented here covers 584 COI DNA barcodes grouped into 23 Barcode Index Numbers (BINs), which genetic (more than 80% Madeira fauna). Our study shows that barcode clusters...
Abstract Because of the slow current velocity, man-made ditches may create distinct physical and ecological conditions that are suitable for growth zooplankton populations. However, influence drainage on communities has not been studied yet. This study aims to answer following questions: i) Are a rich source zooplankton? ii) What velocity value leads abundant in ditches? iii) Do differ between connected natural streams? In with water lower than 0.1 m s -1 , abundance was greater majority...
Lake depth and the consequent mixing regime thermal structure have profound effects on ecosystem functioning, because strongly affects availability of nutrients, light, oxygen. All these conditions influence patterns zooplankton diversity. Zooplankton are a key component aquatic environment essential to maintaining natural processes in freshwater ecosystems. However, biodiversity can be different regard depth, type trophic state. Therefore, aim this study was examine how affect diversity...
Abstract Thermal tolerance is a critical factor influencing the survival of living organisms. This study focuses on thermal resistance copepod species, Thermocyclops crassus (Fischer, 1853) and T. oithonoides (Sars G.O., 1863), with overlapping distribution ranges in Europe. Short-term heat shock experiments were conducted to assess these copepods, considering various temperature increments exposure durations. Additionally, explored influence egg sac shedding, vital indicator population...
The reduced zooplankton abundance at the outlet sections of lakes depends on occurrence preying fry. Therefore, light conditions can play a major role in drift along river outlets. aim this study was to determine influence diurnal decline densities lake Photosynthetically active radiation (PAR) levels were measured their effect rate abundance. Cladocerans and copepods showed significantly greater reduction than rotifers nauplii. A significant positive relationship observed between PAR...
Thermal pollution leads to short-term heat shock in aquatic invertebrates; however, the modulation of tolerance and life history these invertebrates by thermal stress varies among regions, phenology, species, their acclimation. To assess effect shock, we conducted experiments on Daphnia magna Eurytemora carolleeae at 25 °C, 30 35 40 °C (in relation 20 °C) a different exposure time stressor (10, 30, 60 min). The results showed that increased mortality reduced fertility studied planktonic...
Abstract Small human‐made dams and beaver ponds cause significant changes in the environment of small streams. The decreased current velocity increased water retention time these impoundments favour development limnetic organisms, for example, zooplankton. However, reservoirs are regulated, deep narrow, whereas beavers create relatively large with numerous shallow patches their impact on stream zooplankton communities can be different. We compared effect Three sample collection sites were...
The threats to small urban streams lead a decrease in their water quality and dysregulate ecological balance, thereby affecting the biodiversity causing degradation of indicators that determine potential. aim our study was impact abiotic conditions induced by intensive human activity on community structures invertebrates (zooplankton macroinvertebrates) stream Bukówka Szczecin agglomeration (NW Poland). This exhibits same characteristics as large river, which mass live organic matter...
The main objective of this study was to examine the spatial distribution patterns aquatic invertebrates in an environment characterized by significant anthropogenic stress. During entire research period, at all sites, we noticed 72 taxa zooplankton and 30 macroinvertebrates. Variation partitioning analysis reveals that assemblages planktonic organisms are much more determined time sampling rather than site, contrary macroinvertebrates where only slightly responsible for composition benthic...
Abstract The predatory cladoceran Bythotrephes is one of North America’s most successful and impactive invasive species in freshwater plankton communities. taxonomic status the genus Leydig, 1860 (Crustacea: Cladocera: Cercopagididae) has remained unclear a subject intensive debate for over 150 years. We applied an integrative taxonomy approach with multi-gene analysis (mitochondrial COI 12S genes, nuclear 18S 28S genes) on 80 individuals (representing at least four morphospecies) from...
