The authors have quantified the long-term temperature changes in 139 lakes worldwide. They analysed shifts in thermal habitats and found that as lakes warm, species will need to shift to different depths or seasons. Lakes in the tropics are particularly affected.

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.

Freshwater megafauna are vulnerable to extinction, with over 50% of all classified species considered as threatened on the IUCN Red List. The authors found that human impact and traits related to species’ recovery potential including life span, age at maturity, and fecundity jointly determine their extinction risk. In addition, 17 out of 49 unclassified species were predicted to be threatened.

The year 2020 marked the end of the "UN Decade of Biodiversity". However, the final UN report showed that none of the 20 Aichi-Biodiversity Targets, agreed in 2010, have been achieved. Recognizing the perilous state of freshwater biodiversity, a research team led by IGB has issued 14 recommendations for political follow-up agreements on the protection of biological diversity.
