ABSTRACT Vertical migration is a geographically and taxonomically widespread behaviour among zooplankton that spans across diel seasonal timescales. The shorter‐term vertical (DVM) has periodicity of up to 1 day was first described by the French naturalist Georges Cuvier in 1817. In 1888, German marine biologist Carl Chun longer‐term (SVM), which ca . year. proximate control adaptive significance DVM have been extensively studied are well understood. generally controlled ambient irradiance,...
A more profound comprehension of various facets biodiversity is essential for advancing sustainable governance and its associated ecosystem services. In this study, we delved into the composition beta diversity within macroinvertebrates communities in Thousand Islands Lake catchment area. Subsequently, investigated factors influencing diverse alpha diversity, ultimately employed structural equation modeling to analyze pathways through which both regional environmental factors, like climate...
Abstract Worldwide, many coastal freshwater ecosystems suffer from seawater intrusion. In addition to this stressor, it is likely that the biota inhabiting these will also need deal with climate change-related temperature fluctuations. The resilience of populations long-term exposure stressors depend on their genetic diversity, a key for adaptation changing environments. Accordingly, study aimed understand effects salinity and population density dynamics rotifer Brachionus calyciflorus by...
Abstract Sea level rise is expected to continue apace, with a concomitant in temperature on the globe's surface. Natural populations genetic pool compromised by increased salinity would contribute decrease resilience under future changes. Therefore, this work aimed understand long-term effects of salinization diversity cladoceran-simulated laboratory population different regimes. For that, six clonal lineages cladoceran Daphnia longispina were chosen based their reported differential lethal...
Agrochemicals are the main pollutants in freshwater ecosystems. Metazachlor and flufenacet two common herbicides applied fall (i.e., August–October) to agricultural fields Northern Germany. High concentrations of these often found adjacent aquatic Phytoplankton one highly susceptible non-targeted organismal groups for effects on phytoplankton may initiate a chain consequences meta communities through trophic interactions. Few studies have focused responses community metazachlor and, no...
Abstract Tenualosa ilisha also known as Hilsa shad is one of the important anadromous fish species in South Asia and some middle eastern countries because its economic, cultural ecological significance. The importance hilsa this region has driven a large number scientific studies quantification these to identify knowledge gaps future research directions. For purpose, we conducted scientometric analysis on published Web Science database between 2000 2022. Our results indicated that articles...
Stream biofilms play an important role in the structure, functioning, and integrity of agricultural streams. In many lowland streams, macrophyte vegetation is abundant functions as substrate for biofilm (epiphyton) addition to gravel stone epilithon on stream bed. We expect that reach-scale habitat conditions streams (e.g., nutrient availability, hydraulic conditions) affect epiphyton biomass composition, this effect will be substrate-specific (macrophytes stones). The objectives our study...
Herbicides are important, ubiquitous environmental contaminants, but little is known about their interaction with bacterial aquatic communities. Here, we sampled a protected natural freshwater habitat and characterised its microbiome in herbicides. We evolved the microbiomes microcosm assay of exposure (28 days) to flufenacet metazachlor at concentrations 0.5, 5 50 μg L-1 . Inhibitory effects herbicides were exemplarily assessed cultured bacteria from same pond (Pseudomonas alcaligenes,...
Trophic state of a reservoir is one the important factors in limnological perspective order to understand its healthiness. This study was focused dynamics trophic and water quality Sooriyawewa Southern province Sri Lanka. Water evaluated six sampling sites from August 2014 March 2015 using standard methods. Significant temporal variation (p<0.05) observed for chlorophyll-a (14.63±14.2 mg L-1), NO3-(2.77±1.4 PO43-(0.21±0.1 total suspended solids (15.24±10 mgL-1), conductivity (253.75±86.2...
