Estimating biodiversity change across the planet in the context of widespread human
modification is a critical challenge. Here, we review how biodiversity has changed in recent …

Chapter 2, building on prior assessments, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …

Sparked by reports of insect declines of unexpected extent, there has been a surge in the
compilation and analysis of insect time series data. While this effort has led to valuable …

Although species are being lost at alarming rates, previous research has provided
conflicting results on the extent and even direction of global biodiversity change at the local …

Temporal trends in insect numbers vary across studies and habitats, but drivers are poorly
understood. Suitable long-term data are scant and biased, and interpretations of trends …

There is mounting evidence that terrestrial arthropods are declining rapidly in many areas of
the world. It is unclear whether freshwater invertebrates, which are key providers of …

Widespread and significant declines of insect population abundances and biomass are
currently one of the most pressing issues in entomology, ecology and conservation biology …

Abstract The Millennium Ecosystem Assessment assessed ecosystem change, human
wellbeing and scientific evidence for sustainable use of biological systems. Despite …

Major displacement of arctic-alpine species towards higher elevations and latitudes is
anticipated under climate warming. Disjunct plant populations persisting on mountains at the …

Background Recent studies indicate a partial recovery of European stream
macroinvertebrate diversity. However, the key determinants sha** the overall community …
