The study provides insights into how large-bodied marine predators react toward wildlife tourism associated provisioning and allows further discussion about daily energy uptake during provisioning dives, its potential impacts on the ecological role of the target species and associated management measures. 

A research team has studied the close relationships between infectious diseases and biological invasions. The "One Health" approach considers the health of humans as well as animals, plants and other elements of the environment to prevent pandemics and the spread of invasive alien species.

Molecular survey methods detecting DNA released by target-species into their environment (eDNA) provide cost-effective tools for conservation, yet such eDNA-based methods are prone to errors. The authors synthesized recent advances in data processing tools that increase the reliability of interpretations drawn from eDNA data.

Invasion science is the systematic investigation of the causes and consequences of biological invasions. The authors identified four priority areas to advance the field in the Anthropocene: (1) predicting impacts of biological invasions, (2) understanding synergisms of multiple environmental stressors, (3) resolving the taxonomic impediment, and (4) enhancing international biosecurity.

Diversity and community composition of bacteria along vertical gradients were studied in Lake Issyk Kul, Kyrgyzstan, the 6th deepest lake worldwide and the largest high-altitude lake. In the molecular assessment, the 16S rRNA gene analysis revealed significant changes in the composition, responding mainly to depth and salinity with Planctomycetes and Chloroflexi dominating in the deepest layers.

Alien birds can have severe impacts on native birds. The authors wanted to find out whether there are certain factors that make some native bird species more vulnerable to such impacts than others. They identified several factors that increase vulnerability, as well as specific orders of native birds that may require protection, and locations where impacts may be particularly damaging.

Using a dataset of 979 introductions of 173 mammal species worldwide, the authors investigated the hypothesis that the establishment success of alien species depends on the match between environmental conditions in the exotic and native range. The study results support this hypothesis. They are based on the Niche Margin Index, which is presented as a new analysis tool in the paper.

In the current era of Big Data, synthesis tools are critical means to handle the deluge of information. The hierarchy-of-hypotheses (HoH) approach is such a tool that helps to (a) organize evidence, (b) organize theory and (c) closely connect evidence to theory. In this paper, the authors outline the HoH approach and offer guidance on how to apply it, using examples from ecology and evolution.
