Immunogold-labeled S-phase neoblasts, total neoblast number, their distribution, and evidence for arrested neoblasts in Macrostomum lignano (Platyhelminthes, Rhabditophora)
Neoblasts in Platyhelminthes are the only cells to proliferate and differentiate into all cell types. In Macrostomum lignano, the incorporation of 5′-bromo-2′-deoxyuridine (BrdU) in neoblastsExpand

Effect of Various Xenobiotics on Hatching Success of Spodoptera exigua Eggs as Compared to a Natural Plant Extract
The effects of fenitrothion, carbaryl, and mancozeb, present in polluted water and plant extracted glycoalkaloids, were examined on hatching success of Spodoptera exigua eggs. All chemicals producedExpand

Demographic Correlates of Sexual Size Dimorphism and Male Genital Size in the Lice Philopterus coarctatus
Abstract Sexual selection is an influential agent of evolution, often shaping the sex ratio, sexual size dimorphism (SSD), and genital size in animals. To explore its effects in ectoparasites, weExpand

Patterns in the distribution of avian lice (Phthiraptera: Amblycera, Ischnocera) living on the great grey shrike Lanius excubitor
The lice parasite community of great grey shrike Lanius excubitor collected in NE Slovakia during 1962–1974 was quantitatively studied. Lice fauna comprised of three species: Docophorulus coarctatus,Expand
