The dynamics of predation on parasites within prey has received relatively little attention despite the profound effects this is likely to have on both prey and parasite numbers and hence on biological control programmes where parasites are employed. The nematode Phasmarhabditis hermaphrodita is a commercially available biological agent against slugs. Predation on these slugs may, at the same t...

While carnivores are known to be attracted to herbivore-induced plant volatiles, little is known about how such volatiles may affect the behaviour of omnivorous predators that may use both plants and herbivores as food. Here, we examine how systemically produced plant volatiles, in response to local herbivore damage, differentially attract a key omnivorous predator, Anthocoris nemorum (Heteropt...

The Anthocoris nemorum group belongs to the Anthocoridae (Hemiptera), and is an important group of predators of agricultural pests. A phylogeny was constructed in conjunction with dispersal-vicariance analysis of the Anthocoris nemorum group species in order to discern the relationships between the phylogeographical structuring of A. nemorum group species, and the effects of the Qinghai-Tibet p...

Medicinal plants belongs to the oldest known health care products that have been used by mankind all over the world in the form of folklore medicines or traditional medicines or ethno medicines. The use of herbal drugs, extracts and their remedies have significantly increased throughout the world and the ‘green revolution’ in terms of herbal medicines has now achieved astonishing popularity. Th...

Variation in the shell colour and banding polymorphism of Cepaea nemoralis was recorded 20 sites Minsk, Belarus (a total 3965 adults collected 2014–2021). This variation compared with that 16 from Lviv, Western Ukraine (total 3235 2019–2021). Unlike a remarkable spatial differentiation phenotypic composition found Minsk. The samples north-eastern part Minsk were characterized by greater degree ...

Natural history collections are an important and largely untapped source of long-term data on evolutionary changes in wild populations. Here, we utilize three large geo-referenced sets of samples of the common European land-snail Cepaea nemoralis stored in the collection of Naturalis Biodiversity Center in Leiden, the Netherlands. Resampling of these populations allowed us to gain insight into ...
