The Environmental Impact Classification for Alien Taxa (EICAT) has been adopted as an International Union for Conservation of Nature (IUCN) standard to measure the severity of environmental impacts caused by organisms living outside their native ranges. This article clarifies the underlying principles, objectives, and uses of EICAT.

Increasing droughts require a better understanding of connectivity and groundwater-surface water interactions. The authors used a multi-proxy approach of isotope tracers, groundwater data and geophysics to develop a conceptual model of landscape connectivity and groundwater recharge and assessed the effects of land use and catchment properties of groundwater systems sensitive to climate change.

Since the simulation of evaporation and vegetation response to moisture deficits is subject to uncertainties, the authors assessed the benefits of integrating satellite-based land surface temperature data into ecohydrological modelling. They show that even few satellite images can reduce uncertainties of vegetation parameters and improve simulated spatial patterns of land surface temperature.

The authors included effects of intraspecific variation to a variance partitioning method that allows quantifying effects of losses and gains of inter- and intraspecific groups to changes in ecosystem functioning. The method will also provide information on how biodiversity loss at different ecological levels changes ecosystem functioning.

By altering essential environmental cues Artificial Light at Night (ALAN) is restructuring if, how and when animals interact. In this publication the authors explored the role of ALAN on ecological interactions and reviewed research studies that addressed this issue, most of whom were just published during the last three to five years.

This study combines experiments in large enclosures with a comprehensive time series and a field survey to assess the joint effects of storm-induced lake browning, nutrient enrichment and deep-mixing on phytoplankton.Browning decreases nutrient enrichment effects on phytoplankton, including shifts in the species composition from cyanobacteria and chlorophytes to mixotrophic cryptophytes. 

Freshwater ecosystems across the world are biodiversity hotspots but also disproportionately threatened by light pollution. In this review the authors provide a synthesis of current knowledge on light characteristics and the ecological consequences of artificial light in inland waters and coupled adjacent ecosystems. The focus is on recent insights into effects and on ways to mitigate them.

This study extends the concept of flagship species to include individual organisms, who can garner public attention and attract conservation support. Flagship individuals typically share a similar suite of characteristics, including: (1) charismatic species-level traits; (2) unique or distinctive individual traits; (3) a high degree of exposure to humans; and (4) a noteworthy life history or fate.
