Insect pollinators of crops and wild plants are under threat globally and their decline or loss
could have profound economic and environmental consequences. Here, we argue that …

Because biodiversity is multidimensional and scale‐dependent, it is challenging to estimate
its change. However, it is unclear (1) how much scale‐dependence matters for empirical …

Concern about biodiversity loss has led to increased public investment in conservation.
Whereas there is a widespread perception that such initiatives have been unsuccessful …

Humans have elevated global extinction rates and thus lowered global scale species
richness. However, there is no a priori reason to expect that losses of global species …

Estimates of recent biodiversity change remain inconsistent, debated, and infrequently
assessed for their functional implications. Here, we report that spatial scale and type of …

To study insect decline, an important threat to biodiversity, long‐term datasets are needed.
Here we present a study of hoverfly (Diptera: Syrphidae) abundance and diversity in a Dutch …

There is increasing concern about the decline of pollinators worldwide. However, despite
reports that pollinator declines are widespread, data are scarce and often geographically …

Aim To quantify spatio‐temporal changes in species richness and assemblage composition
of Danish butterflies over more than 100 years and to assess whether different functional …

Accumulating evidence shows that landscape fragmentation drives the observed worldwide
decline in populations of pollinators, particularly in species of Lepidoptera and …

Natural habitat may deliver ecosystem services to agriculture through the provision of
natural enemies of agricultural pests. Natural or non-crop habitat has strongly positive …
