TL;DR: Defaunation is both a pervasive component of the planet’s sixth mass extinction and also a major driver of global ecological change.

TL;DR: A range of mechanisms underpinning the resilience of ecosystem functions across three ecological scales are identified and biodiversity, encompassing variation from within species to across landscapes, may be crucial for the longer-term resilience ofcosystem functions and the services that they underpin.

TL;DR: A simple index is defined that measures the contribution made by different species to phylogenetic diversity and how the index might contribute towards species-based conservation priorities and suggests that global conservation priorities may have to be reassessed in order to prevent a disproportionately large amount of mammalian evolutionary history becoming extinct in the near future.

TL;DR: Users must acknowledge the limitations of taxonomic species and avoid unrealistic expectations of species lists, and decide on a standardized, universal species list to ameliorate the mismatch between taxonomy and the uses to which it is put.

TL;DR: Powney et al. as discussed by the authors used occupancy models to estimate the degree of loss in wild bee and hoverfly species across Great Britain, and report a 55% decline in upland species and a 12% increase in dominant crop pollinators.
