Neoseiulus roumelioticus Papadoulis, Emmanouel & Kapaxidi (Acari: Phytoseiidae), a predatory mite previously known only from its original description Greece, is reported for the first time in Turkey. The species re-described and illustrated, based on specimens collected an unknown of plant family Asteraceae Çilingöz Nature Park Istanbul Province,

1. Predator-mediated coexistence occurs when predation allows competitors to coexist, due to preferential consumption of a superior competitor relative to an inferior competitor. Differences between the native treehole mosquito (Aedes triseriatus) and the co-occurring Asian tiger mosquito (Aedes albopictus) in anti-predatory larval behaviours account, in part, for the greater vulnerability of t...

New hosts and parasitism notes for the mite Leptus (Acari: Erythraeidae) in Brazil. Larval erythraeid mites are common ectoparasites of harvestmen (Opiliones). Studies describing insects as potential hosts have received little attention. Specimens of an undescribed species of the genus Leptus were collected in association with predatory and phytophagous Heteroptera bugs in a secondary forest in...

Mercury (Hg) and its compounds, which pose a health risk to the population not engaged in hazardous industries, enter human body mainly with food items. First of all, these are seafood, fish canned fish. In this study, concentrations Hg muscles different species from water bodies Yaroslavl province were determined. The average values mercury content range 0.03 0.41 mg/kg wet weight. recorded le...

1. Interference between predator species frequently decreases predation rates, lowering the risk of predation for shared prey. However, such interference can also occur between conspecific predators. 2. Therefore, to understand the importance of predator biodiversity and the degree that predator species can be considered functionally interchangeable, we determined the degree of additivity and r...

objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats.  methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...

The tiger shark, Galeocerdo cuvier, is the largest predatory fish in tropical waters. Due to its wide-ranging movements, diverse diet and perceived potential threat to humans, the feeding behavior of this species has received significant attention in the scientific literature for over 40 years. Such studies have identified various prey items and feeding strategies for tiger sharks worldwide, an...

Several spider taxa are specialized to prey on ants. Some species of Zodariidae are known to use specialized tactics to capture ants. In this study, I assessed the diet difference and predatory behavior of the Japanese zodariid Asceua japonica. In a series of surveys, all observed individuals in the field preyed on tiny arboreal ants representing several subfamilies. In addition, the species us...

Callococcithrips gen.n. is erected for the species Rhynchothrips fuscipennis Moulton that lives only among the protective waxy secretions of an eriococcid on Kunzea in south-eastern Australia. Larvae and adults of this thrips move rapidly amongst the sticky wax strands, and their maxillary stylets are unusually long and convoluted. Circumstantial evidence suggests that the thrips is predatory o...

BACKGROUND Understanding the current status of predatory fish communities, and the effects fishing has on them, is vitally important information for management. However, data are often insufficient at region-wide scales to assess the effects of extraction in coral reef ecosystems of developing nations. METHODOLOGY/PRINCIPAL FINDINGS Here, I overcome this difficulty by using a publicly accessi...
