Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Patterns of understorey bird diversity across Amazonian forests: survey effort and range maps predict local species richness

open access: yesEcography, EarlyView.
Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Succession stages‐dependent shifts in grassland community stability from asynchrony to population stability mediated by nitrogen enrichment

open access: yesEcography, EarlyView.
Understanding the stability dynamics of naturally occurring grassland succession under nutrient enrichment is crucial for effective ecosystem management. We carried out an 11‐year field experiment to examine how grassland community stability responds to nitrogen (N) enrichment across the three successional stages (early‐, mid‐ and late‐successional ...
