Zusammenfassung Die Studie untersucht die Entwicklung der Grundwasserstände in Deutschland anhand von 5844 Messstellen sowie deren Reaktionsdynamik gegenüber klimatologischen Antrieben im Referenzzeitraum 1991–2020. Zusätzlich wird die Entwicklung seit 2018 im Kontext der außergewöhnlichen Dürreperiode betrachtet, um die Reaktionsfähigkeit und Vulnerabilität der Grundwassersysteme gegenüber extremen klimatischen Bedingungen zu...

There is a common saying in business that “what matters gets measured”. Environmental protection and sustainability certainly should qualify as important concerns for both businesses and governments. The 1970s marked the genesis of the modern environmental movement, with growing concern about water pollution in the United States (U.S.). In 1972, the U.S. enacted the Clean Water Act (CWA) “ to restore and maintain the chemical,...

Organisms inhabiting highly seasonal environments must cope with a wide range of environmentally induced challenges. Many seasonal challenges require extensive physiological modification to survive. In winter, to survive extreme cold and limited resources, insects commonly enter diapause, which is an endogenously derived dormant state associated with minimized cellular processes and low energetic expenditure. Due to the high d...

How organisms that are part of the same trophic network respond to environmental variability over small spatial scales has been studied in a multitude of systems. Prevailing theory suggests a large role for plasticity in key traits among interacting species that allows matching of life cycles or life‐history traits across environmental gradients, for instance insects tracking host‐plant phenology across variable environments (...

Diapause is a common adaptation for overwintering in insects that is characterized by arrested development and increased tolerance to stress and cold. While the expression of specific candidate genes during diapause have been investigated, there is no general understanding of the dynamics of the transcriptional landscape as a whole during the extended diapause phenotype. Such a detailed temporal insight is important as diapaus...

Although cyanobacterial harmful algal blooms (CHABs) are promoted by nutrient loading and elevated temperatures, the effects of these processes on bloom diversity are unclear. This study used traditional and next‐generation sequencing approaches to assess shifts in phytoplankton, cyanobacterial (16S rRNA), and microcystin‐producing ( mcy E) communities during CHABs in western Lake Erie (Maumee and Sandusky Bays) in response to...

Diarrhetic Shellfish Poisoning (DSP) is a globally significant human health syndrome most commonly caused by dinoflagellates of the genus Dinophysis . While ecosystem studies suggest that blooms of this mixotrophic dinoflagellate can be promoted by excessive nitrogen (N) loading, it is unclear whether these effects are direct (nutrient stimulation of Dinophysis ) or indirect (nutrient stimulation of prey) since this alga is mi...
