Aim To describe the patterns and trends in the spread of crop pests and pathogens around
the world, and determine the socioeconomic, environmental and biological factors underlying …

Global food security is threatened by the emergence and spread of crop pests and pathogens.
Spread is facilitated primarily by human transportation, but there is increasing concern …

Plant disease outbreaks are increasing and threaten food security for the vulnerable in many
areas of the world. Now a global human pandemic is threatening the health of millions on …

Despite the importance of species discovery, the processes including collecting, recognizing,
and describing new species are poorly understood. Data are presented for flowering plants…

The relationship between species richness and ecosystem function, as measured by
productivity or biomass, is of long‐standing theoretical and practical interest in ecology. This is …

A common approach to estimating the total number of extant species in a taxonomic group
is to extrapolate from the temporal pattern of known species descriptions. A formal statistical …

Wheat stem rust, a devastating disease of wheat and barley caused by the fungal pathogen
Puccinia graminis f. sp. tritici, was largely eradicated in Western Europe during the mid-to-…

Emerging fungal and oomycete pathogens infect staple calorie crops and economically
important commodity crops, thereby posing a significant risk to global food security. Our current …

Global food security is strongly determined by crop production. Climate change-induced losses
to production can occur directly or indirectly, including via the distributions and impacts of …

Transport networks are ubiquitous in both social and biological systems. Robust network
performance involves a complex trade-off involving cost, transport efficiency, and fault tolerance…
