Spatial and temporal dynamics of water isotopes in the riverine-marine mixing zone along the German Baltic Sea coast
The spatial and temporal variability of stable water isotopes were investigated in the Schlei and in the Baltic Sea boddens. The data improve the understanding of hydrological processes behind those dynamics. Further they will be a helpful contribution to multiple IGB projects, e.g. in context of migration studies of pike and analysis of biochemical processes in macrophytes
The LOTUS initiative for open knowledge management in natural products research
Scientists integrated data about natural chemical compounds and the organisms they have been documented in, provided literature references and exposed the information both as a stand-alone database and via Wikidata.The database enables queries that relate natural chemical compounds to the taxa they have been found in and the literature documenting the evidence.
Fate of trace organic compounds in the hyporheic zone: influence of microbial metabolism
The authors investigated the influence of microbial processes on the fate of trace organic compounds in stream sediments. The study demonstrates the usefulness of the fluorescent tracer system resazurin-resorufin for determining microbial metabolism and disentangling specific reactive properties and ultimately their influence on the fate of contaminants in natural hyporheic zones.
Urban affinity and its associated traits: a global analysis of bats
The authors developed indices to quantify the urban affinity of species by using publicly available occurrence data and examined the performance of these indices using a global dataset of bats. The results show that simple indices are appropriate and most practical for producing quantitative assessments of species’ urban affinity.
Organizational principles of hyporheic exchange flow and biogeochemical cycling in river networks across scales
Understanding organizational principles of hyporheic exchange flow and biogeochemical cycling in landscapes is key for generalizing process knowledge.
Dynamics of greenhouse gases (CH4 and CO2) in meromictic Lake Burgsee, Germany
At its deepest point, Lake Burgsee has one of the highest methane concentrations ever measured in a natural freshwater lake.
Identification and characterization of a new family of long satellite DNA, specific of true toads (Anura, Amphibia, Bufonidae)
This newly discovered family of satellite DNAs is present in 15 examined species of amphibians of the systematic family of True toads (Bufonidae). It is formed by monomers of 807 bp, organized in tandem arrays, and has an AT-content of 57.4 Percent.
The EICAT+ framework enables classification of positive impacts of alien taxa on native biodiversity
The IUCN Environmental Impact Classification for Alien Taxa (EICAT) is a global standard to assess negative impacts of alien species on native biodiversity. This paper presents EICAT+, a complementary framework using 5 semiquantitative scenarios to classify the magnitude of positive impacts that alien species have on biodiversity.
Biological invasions reveal how niche change affects the transferability of species distribution models
It is widely debated if species distribution models are transferable across space and time. The authors synthesized results on 217 species from 50 studies to elucidate effects of niche change on model transferability. They found that niche change reduced model transferability; however, a lack of presence points for developing models led to an even stronger reduction in transferability.
Equilibrated evolution of the mixed auto-/allopolyploid haplotype-resolved genome of the invasive hexaploid Prussian carp
The Prussian carp or Gibel carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish. The authors have for the first time described the complete genome of the Prussian carp.This also provides a much better understanding of its unusual reproductive method and to improve its management.
