Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

Insect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

Restoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐

The cyanogenic polymorphism in Trifolium repens L. (white clover) [PDF]

Heredity, 1991
The cyanogenic polymorphism in white clover is controlled by alleles of two independently segregating loci. Biochemical studies have shown that non-functional alleles of the Ac locus, which controls the level of cyanoglucoside produced in leaf tissue, result in the loss of several steps in the biosynthetic pathway.

Forage mass, accumulation, and nutritive value of four perennial forages grown in a loblolly pine silvopasture in the Mid‐South United States

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Establishing forage in loblolly pine (Pinus taeda L.) plantations has the potential to increase grazing acreage for cattle farms in the Mid‐South, but appropriate species selection still requires investigation. The objective was to evaluate forage mass, accumulation, and nutritive value of four perennial forage species, novel‐endophyte tall ...

Sowing ratio, NS fertilisation and interactions of Lolium sp. and Festulolium grown in mixtures with Trifolium repens

Plant, Soil and Environment, 2020
Current ecological trends for production of forage for livestock indicate a need for small usage of fertilisers while increasing productivity. The study aimed to assess yield and interactions of selected Lolium and Festulolium species grown in mixtures ...

THE POSTGENITAL FUSION IN THE GYNOECIUM OF TRIFOLIUM REPENS L.: LIGHT AND ELECTRON MICROSCOPICAL ASPECTS

Acta Botanica Neerlandica, 1973
SUMMARY The postgenital fusion between the carpellary margins in the gynoecium of Trifolium repens L. was studied in different ontogenetical stages by means of light and electron microscopy. The results of both methods are correlated. With light microscopy the place of fusion could be inferred by histogenetical analysis of serial sections ...

Whole Genome Assembly and Annotation of Two Invasive Sitona Species

Journal of Applied Entomology, Volume 150, Issue 8, Page 1025-1034, September 2026.
ABSTRACT Weevils are a highly diversified taxon, comprising about 70,000 described species, including many of high economic importance. Here, we present whole genome assemblies and annotations of two Sitona species (Coleoptera: Curculionidae: Entiminae).
