Worldwide moderate-resolution mapping of lake surface chl-a reveals variable responses to global change (1997–2020)

Benjamin M. Kraemer; Karan Kakouei; Catalina Munteanu; Michael W. Thayne; Rita Adrian

Whether a lake appears blue or green is also related to its chlorophyll-a content. Researchers led by IGB used satellite data to draw conclusions about the concentrations of the green pigment produced by algae.

Towards critical white ice conditions in lakes under global warming

Gesa A. Weyhenmeyer ... Hans-Peter Grossart ...

The quality of lake ice is of paramount importance for ice safety and lake ecology under ice. In 2020/2021, the researchers conducted a coordinated sampling campaign of lake ice quality during one of the warmest winters since 1880. They showed that lake ice during this period generally consisted of unstable white ice, which at times accounted for up to 100 percent of the total ice thickness.

The era of reference genomes in conservation genomics

Giulio Formenti; Kathrin Theissinger; Carlos Fernandes; Iliana Bista; Aureliano Bombarely ... Michael T. Monaghan

The European Reference Genome Atlas (ERGA) is a pan-European scientific response to the current threats to biodiversity that aims to generate reference genomes of eukaryotic species across the tree of life. ERGA reference genomes will include threatened, endemic, and keystone species, as well as pests and species important to agriculture, fisheries, and ecosystem function.

Antecedent lake conditions shape resistance and resilience of a shallow lake ecosystem following extreme wind storms

Michael W. Thayne; Benjamin M. Kraemer; Jorrit P. Mesman; Bastiaan W. Ibelings; Rita Adrian

The goal was to develop a systematic, standardized and quantitative methodology for the synthesis of resistance and resilience relative to short-term lake and extreme storm conditions. Resistance and resilience following extreme storms are primarily shaped by antecedent turbidity and thermal conditions. Increased storm intensity and duration diminish resistance and resilience of the lake.

Cross-continental importance of CH4 emissions from dry inland-waters

José R. Paranaíba; Ralf Aben; Nathan Barros; Gabrielle Quadra; Annika Linkhorst; André M. Amado; Soren Brothers; Núria Catalán; Jason Condon; Colin M. Finlayson; Hans-Peter Grossart; Julia Howitt; Ernandes S. Oliveira Junior; Philipp S. Keller; Matthias Koschorreck; Alo Laaso; Catherine Leigh; Rafael Marcé; Raquel Mendonça; Claumir C. Muniz; Biel Obrador; Gabriela Onandia; Diego Raymundo; Florian Reverey; Fábio Roland; Eva-Ingrid Rõõmo; Sebastian Sobek; Daniel von Schiller; Haijun Wang; Sarian Kosten

Despite significant progress in quantifying greenhouse gas emissions from dry inland waters, little is known about methane (CH4). The authors determined CH4 emissions from dry sediments across continents and found that the CH4 contribution ranged from 10 to 21% of the equivalent CO2 emissions. Therefore, CH4 emissions from dry inland waters should be considered for the global carbon cycle.

Warming alters juvenile carp effects on macrophytes resulting in a shift to turbid conditions in freshwater mesocosms

Peiyu Zhang; Huan Zhang; Huan Wang; Sabine Hilt; Chao Li; Chen Yu; Min Zhang; Jun Xu

The authors tested the single and combined effects of warmer water (+4.5°C) and benthivorous juvenile common carp on aquatic macrophytes in 24 mesocosms (2500 L). Our study provides evidence for a regime shift from clear-water conditions dominated by submerged or floating-leaved macrophytes to a turbid state triggered by warming impacts on benthivorous fish rather than on macrophytes.

Climate-induced forest dieback drives compositional changes in insect communities that are more pronounced for rare species

Lucas Sire; Paul Schmidt Yáñez; Cai Wang; Annie Bézier; Béatrice Courtial; Jérémy Cours; Diego Fontaneto; Laurent Larrieu; Christophe Bouget; Simon Thorn; Jörg Müller; Douglas W. Yu; Michael T. Monaghan; Elisabeth A. Herniou; Carlos Lopez-Vaamonde

Insects declines are now recognised as a consequence of global change. The authors set out to determine the role of drought-induced forest decline in these changes. Using field samples in the Pyrenees and DNA-metabarcoding to determine the species that occur there, they found no loss of species richness in forests experiencing tree loss, but uncovered large differences in the insect communities.

Rusak; Steven Sadro; Emilie Saulnier-Talbot; Martin Schmid; Ruben Sommaruga; Wim Thiery; Piet Verburg; Kathleen C. Weathers; Gesa A. Weyhenmeyer; Kiyoko Yokota; Kevin C. Rose

The authors analyzed a combined total of 45,148 dissolved oxygen and temperature profiles and calculate trends for 393 temperate lakes that span 1941 to 2017. They found that a decline in dissolved oxygen is widespread in surface and deep-water habitats. Declines in dissolved oxygen in freshwater are 2.75 to 9.3 times greater than observed in the world’s ocean.

Recovery of freshwater microbial communities after extreme rain events is mediated by cyclic succession

Tanja Shabarova; Michaela M. Salcher; Petr Porcal; Petr Znachor; Jiří Nedoma; Hans-Peter Grossart; Jaromír Seda; Josef Hejzlar; Karel Šimek

The authors investigated the resilience of aquatic microbial communities, especially in small ponds, against flooding events. The most interesting result of their high temporal-resolution study was that the microbial communities, in particular bacteria, were surprisingly resilient against flooding events and that bacterial community repeatedly showed a defined path of recovery.

Marine algae facilitate transfer of microplastics and associated pollutants into food webs

Xiangyu Yang; Hui Wang; Lu Zhang; Lingwei Kong; Yi Chen; Qiang He; Ling Li; Hans-Peter Grossart; Feng Ju

In this conceptual paper, the authors argue that micro- and macro-algae represent an underappreciated, yet, important pathway for transporting microplastics and associated pollutants via marine food webs to humans, facilitating potential invasion of pathogens into the human body. For the assessment of human health risks, interactions between microplastics and algae need to be explored.
