Seedling mortality in arbuscular mycorrhizal systems. Open
Glomeromycota are an ancient lineage of filamentous fungi that have been studied intensively because they associate with plant roots in a symbiosis, the arbuscular mycorrhiza, which may enhance nutrient acquisition. Agricultural practices …

Analyzing patterns of change in the orchid flora of Britain and Ireland with correlated environmental variability Open
Introduction Fifty-seven orchid species have been so far reported to occur naturally in Great Britain and Ireland, some of which are known to have declined over the last century, primarily due to land use changes. In this paper, we examine…

Integration of attractive and defensive phytochemicals is unlikely to constrain chemical diversification in a perennial herb Open
Summary Diversification of plant chemical phenotypes is typically associated with spatially and temporally variable plant–insect interactions. Floral scent is often assumed to be the target of pollinator‐mediated selection, whereas foliar …

Honest floral signalling traits vary across and within populations in an insect‐pollinated plant Open
In flowering plants that produce concealed rewards, pollinator foraging preferences may select for floral advertisement traits that are correlated with rewards. To date, studies have not focused on the potential for honest signals to vary …

The rate of species extinction in declining or fragmented ecological communities Open
Loss of habitat can take many forms, ranging from the fragmentation of once-continuous habitat to the slow erosion of populations across continents. Usually, the harm leading to biodiversity loss is not immediately obvious: there is an ext…

Models of poisoning effects on vulture populations show that small but frequent episodes have a larger effect than large but rare ones Open
Vultures are among the most threatened avian taxa in the world. When vultures aggregate in large numbers to feed, poisoned carcasses can extirpate entire populations at once. In the light of shrinking numbers worldwide, restocking and rein…
