Competition is one of the key drivers cladoceran community dynamics. Competitive abilities can be measured as Threshold Food Concentration (TFC), i.e., concentration food at which population growth rate equals zero. Species with lower TFC should superior competitors. However, vary environmental conditions. We hypothesized that algal phosphorus (P) content influences and alter outcome competition between large small-bodied cladocerans. conducted life table experiments single clones Daphnia...
Cyanobacteria negatively affect zooplankton through several mechanisms including mechanical interference, toxicity, and poor food quality due to a shortage of essential lipids. To understand the nature each these mechanisms, they should be examined independently. The goal our study was assess influence cyanobacteria on competitive outcomes between small-bodied Daphnia longispina large-bodied magna. We conducted life-table experiments R* (population threshold concentration), competition...
Sea dumping of chemical warfare (CW) took place worldwide during the 20th century. Submerged CW included metal bombs and casings that have been exposed for 50–100 years corrosion are now known to be leaking. Therefore, arsenic-based agents (CWAs), pose a potential threat marine ecosystems. The aim this research was support need real-data measurements accurate risk assessments categorization threats originating from submerged CWAs. This has achieved by providing broad insight into CWAs acute...
During the 20th century, thousands of tons munitions containing organoarsenic chemical warfare agents (CWAs) were dumped into oceans, seas and inland waters around world. As a result, CWAs continue to leak from corroding sediments their environmental concentrations are expected peak over next few decades. There remains, however, lack knowledge about potential toxicity aquatic vertebrates, such as fish. The aim this study was fill in gap research, by investigating acute on fish embryos, using...
Sulphur mustard (HD) was the most widely produced chemical warfare agent (CWA) in history of (CW). Simultaneously, loads HD account as by far largest fraction sea-dumped CW. Nowadays its presence marine ecosystems recognized a serious threat for users and maritime industries. Although, during over decade research much has been done to assess environmental threats linked with underwater munitions. There are, however, essential gaps scientific knowledge including scarce information about...
Several hundred thousand tons of chemical warfare agents (CWAs) were disposed at sea, leading to environmental contamination. Among the most toxic and persistent CWAs is adamsite; however, ecotoxicological data on this compound limited. Presented research focuses long-term effects adamsite fish. A 28-day exposure study was conducted, evaluating impact life history parameters (body length, body mass, growth rate), tissue accumulation, expression/activity detoxification-related enzymes in...
Correlative field studies have shown that the food quality of natural seston for Daphnia is highly correlated with content eicosapentaenoic acid (EPA), indicating growth in nature at least seasonally limited by a low availability this polyunsaturated fatty acid. Here we test hypothesis putative limitation due to EPA should lead genetic adaptation physiological traits reflected genotype‐dependent differences ability sympatric clones cope these shortages. We further if provides another...
Several hundred thousand tonnes of munitions containing chemical warfare agents (CWAs) are lying on the seafloor worldwide. CWAs have started leaking from corroded munitions, and their presence in environment organisms inhabiting dump sites has been detected. The water negatively affects fish, macrobenthos free-living bacteria. It can be expected that would also affect gut-associated bacteria which vital for condition. main aim this study was to test if microbiota cod collected Baltic...
A high genetic variation and recurrent changes in the structure have been found many pelagic populations. However, evidence that directly links these to differences ecological performance of particular genotypes is scarce. We hypothesized within Daphnia, specialization clones occurring a season food quality specific for time year responsible observed population. This hypothesis was tested by comparing fitness spring summer Daphnia longispina group, given biochemical relevant seasons....
Abstract Populations of three sympatric species (Daphnia cucullata, Daphnia galeata, and hyalina longispina complex)) inhabiting lakes in northeastern Poland (Roś, Mikołajskie, Wigry) were checked for interspecific hybrids. Hybrid coexisting with parental individuals detected each the investigated lakes. Several classes hybrids (F1, F2, backcrosses), including D. cucullata×galeata×hyalina individuals, have been detected. Hybrids constituted a substantial (13%–38%) part total abundance...
Summary Interspecific hybridisation is common in freshwater cladocerans. Within the Daphnia longispina complex hybrids frequently dominate over parental species, and environmental heterogeneity pelagial of lakes has been invoked to explain coexistence species. In laboratory conditions, I investigated effects filamentous cyanobacteria on relative fitness hyalina , galeata hyalina×galeata hybrids. For each taxon, performance three clones was measured using animals fed with two diets: (i) a...

Potamopyrgus antipodarum (Gray) was recorded from seven of 24 examined lakes the Wigry National Park and river Kamionka.The snail had not been previously lakes: Staw Wigierski, Pierty, Czarne Huciañskie Koleoene.P. inhabits waters varied character (rivers, different morphometry trophy).Its spread in results probably transport by birds humans, to a lesser degree water currents.

Abstract The embryonic stages of the anomopod Bosmina longirostris family Bosminidae were elucidated by scanning electron microscopy. Along with corresponding coregoni described Kotov (2001), these findings have enabled a comparison to Dunhevedia crassa , as representative species Chydoridae, and Eurycercus lamellatus Eurycercidae. In general, developmental patterns are similar in four species, particularly from blastulation first instar. principal difference during embryogenesis is that D....
