ABSTRACT Deciphering sediment provenance is essential to understand depositional patterns and dynamics. This question is particularly important in archaeological contexts to constrain the sedimentological history of unearthed material—an information critically needed, for example, to estimate the age of the deposits—or to apprehend sediment movement ...

Early evolutionary history of the seed
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 ...

Defoliation of common ragweed by Ophraella communa beetle does not affect pollen allergenicity in controlled conditions [PDF]
Ragweed allergy is one of the primary causes of seasonal allergies in Europe and its prevalence is expected to rise. The leaf beetle Ophraella communa, recently and accidentally established in N-Italy and S-Switzerland, represents a promising approach

A spatial representation of the potential ‘adaptation effort’ that might be needed to maintain at least 75% of the species modelled in Biebrza National Park, Poland (white outline), at 1.5°C. The darker the green shading, the less adaptation would be needed.

Entomogenic Climate Change [PDF]
Rapidly expanding insect populations, deforestation, and global climate change threaten to destabilize key planetary carbon pools, especially the Earth's forests which link the micro-ecology of insect infestation to climate.

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

To avoid increased slug damage in strip cropping fields in slug‐prone areas, potential slug‐source crops should be spatially separated from slug‐sensitive crops. However, an increase in slug abundance should not deter the adoption of strip cropping as higher slug damage in strip cropping systems was rarely observed by farmers.

Palaeoenvironment of a mesolithic peat bed from Austin Friars, Leicester [PDF]
A mesolithic peat bed, dated to 9920±100 bp (HAR-4260) (bp = radiocarbon years before the present calculated from A.D. 19S0 within + or - of 100 years in this case. Ed.) was recovered from Austin Friars, Leicester.

Ecological change may be a common initiator of evolutionary pollinator shifts
Summary Although evolutionary pollinator shifts are accepted as major sources of floral and species diversity in angiosperms, the mechanisms triggering pollinator shifts remain largely unexplored. In 1970, Stebbins proposed that ecological change may be a common initiator of evolutionary pollinator shifts, but empirical tests of Stebbins' hypothesis ...
