Insights into the Time Evolution of Slowly Photodegrading Contaminants by Davide Vione

“…Photochemical degradation plays an important role in the attenuation of many recalcitrant pollutants in surface freshwaters. Photoinduced transformation kinetics are strongly affected by environmental conditions, where sunlight irradiance plays the main role, followed by water depth and dissolved organic carbon (DOC). …”

Monitoring Duckweeds (<i>Lemna minor</i>) in Small Rivers Using Sentinel-2 Satellite Imagery: Application of Vegetation and Water Indices to the Lis River (Portugal) by Romeu Gerardo, Isabel P. de Lima

“…Duckweed species, particularly <i>Lemna minor</i>, are widely found in freshwaters all over the world. This macrophyte provides multiple ecosystems’ functions and services, but its excessive proliferation can have negative environmental impacts (including ecological and socio-economic impacts). …”

Are all copepods the same? Variation in copepod stoichiometry with taxonomy, ontogeny, latitude, and habitat by Emily M. Herstoff, Cédric L. Meunier, Maarten Boersma, Stephen Baines

“…Copepod C:N was higher in inland waters compared with animals from marine environments in both copepodites and adult females, matching the higher C content of seston in many inland freshwaters. For both copepodites and adult females, mid‐latitude animals had higher C:N and C:P than high‐latitude animals, which matched predictions based on the availability of nutrients or adaptation to cold environments. …”

Examination of the Metallothionein Gene Family in Greater Duckweed <i>Spirodela polyrhiza</i> by Orathai Pakdee, Shomo Tshering, Prayad Pokethitiyook, Metha Meetam

“…Duckweeds are aquatic plants that proliferate rapidly in a wide range of freshwaters, and they are regarded as a potential source of sustainable biomass for various applications and the cost-effective bioremediation of heavy metal pollutants. …”

Microbial nutrient limitation in Arctic lakes in a permafrost landscape of southwest Greenland by B. Burpee, J. E. Saros, R. M. Northington, K. S. Simon

“…Permafrost is degrading across regions of the Arctic, which can lead to increases in nutrient concentrations in surface freshwaters. The oligotrophic state of many Arctic lakes suggests that enhanced nutrient inputs may have important effects on these systems, but little is known about microbial nutrient limitation patterns in these lakes. …”

A Non-Stressful Temperature Rise and Greater Food Availability Could Increase Tolerance to Calcium Limitation of <i>Daphnia</i> cf. <i>pulex</i> (Sensu Hebert, 1995) Populations in... by Eloísa Ramos-Rodríguez, Carmen Pérez-Martínez, José María Conde-Porcuna

“…Calcium (Ca) is an important driver of community structure in freshwaters. We examined the combined effects of increased temperatures and variations in food quantity on the tolerance to low Ca of <i>Daphnia pulex</i>. …”

Metabarcoding as an effective complement of microscopic studies in revealing the composition of the diatom community – a case study of an oxbow lake of Tisza River (Hungary) with... by Tibor Bíró, Mónika Duleba, Angéla Földi, Keve T. Kiss, Péter Orgoványi, Zsuzsa Trábert, Edit Vadkerti, Carlos E. Wetzel, Éva Ács

“…However, in recent years, DNA-based methods have been proposed and are rapidly growing in the scientific literature as a complementary tool to assess the ecological status of freshwaters. Diatom-based ecological status assessment uses indices calculated from sensitivity and tolerance values as well as relative abundance of species. …”

Detailed analysis of prey taxonomic composition indicates feeding habitat partitioning amongst co-occurring invasive gobies and native European perch by Joanna Grabowska, Mateusz Płóciennik, Michał Grabowski

“…One of the negative impacts of non-native invasive species on trophic interactions in an invaded ecosystem occurs via increased interspecific competition for food resources between the invader and local species of the same food niche. In freshwaters, there are usually several fish species that feed on similar food resources. …”

Temperature Influences the Production and Transport of Saxitoxin and the Expression of sxt Genes in the Cyanobacterium Aphanizomenon gracile by Samuel Cirés, Adrián Delgado, Miguel González-Pleiter, Antonio Quesada

“…The cyanobacterium Aphanizomenon gracile is the most widely distributed producer of the potent neurotoxin saxitoxin in freshwaters. In this work, total and extracellular saxitoxin and the transcriptional response of three genes linked to saxitoxin biosynthesis (sxtA) and transport (sxtM, sxtPer) were assessed in Aphanizomenon gracile UAM529 cultures under temperatures covering its annual cycle (12 °C, 23 °C, and 30 °C). …”
