Effects of spirometrid plerocercoids on several species of lower vertebrates.

Infections of Ligula intestinalis on Freshwater Fish in Kars Plateau of North-Eastern Anatolia, Turkey.

OBJECTIVE This study was conducted to determine the prevalence of Ligula intestinalis and infections caused by these on freshwater fish in rivers and streams in the Kars plateau of north-eastern Anatolia, Turkey. METHODS This research was conducted between April and July 2011. Fish samples were caught via a casting net and an electro-shocker. The samples were immediately examined to determine...

Influence of public road proximity on ground-dwelling insect communities

Ecological studies on road’s impact on wildlife have concentrated on vertebrates although less is known of their effects on invertebrates. The current study presents public road influences on species richness, abundance, and diversity of ground dwelling insects in Arusha National Park in Tanzania. Values from pitfall traps data were generally higher in core habitat than road verge. Nine species...

Occurrence of Schistocephalus solidus in anadromous threespine stickleback.

Plerocercoids of the cestode Schistocephalus solidus are reported for the first time from the body cavity of anadromous threespine stickleback inhabiting Mud Lake, Alaska. Most infected stickleback harbored a single large plerocerciod (mean weight  =  0.447 g, range  =  0.228-0.716 g). The overall prevalence of plerocercoids across genders and 2 yr of samples was 1.4%, but prevalence was signif...

Fipronil: mechanisms of action on various organisms and future relevance for animal models studies

Because insects had developed resistance to several insecticides, today, neonicotinoids and fiproles are used to combat pests. The difference between this two classes of insecticides is that fipronil acts by inhibiting the receptors of nervous cells, while neonicotinoids perturbs the neuronal transmission. The suitable properties of fipronil make that its use to be more obvious on the pesticide...
