Relative collections of house flies were compared on two Florida dairy farms using several monitoring methods: sticky cylinders, baited jug traps (Farnam Terminator and Victor Fly Magnet), and bait strips (Wellmark QuikStrike). Bait strips were placed over collecting pans and under 61 cm square plywood roofs to protect the toxicant from sunlight ("sheltered QuikStrike traps"). Sticky cylinders ...

Abstract The Atlantic slipper snail, Crepidula fornicata, is a filter-feeding gastropod. C. fornicata is a sequential hermaphrodite with a unique reproductive behavior that involves smaller, mobile male slipper snails stacking on top of larger female slipper snails. This association allows males to release sperm in close proximity to fertile females. This study examined the mean size of basal C...

Studies of allozyme variation may reveal unexpected patterns of genetic variation which challenge earlier conclusions of species delimitations based on morphological data. However, allozyme variation alone may not be sufficient to resolve this kind of problem. For example, populations of the marine intertidal snail Littorina fabalis (=Littorina mariae) from wave exposed parts and from protected...

S employment is expanding in many countries with various types of institutions offering an increasing number of positions to persons with disabilities who wish to work. The structures involved are also showing a growing desire for recognition as full participants in the economy and as employing higher professional standards. In fact, many providers of sheltered employment are now using manageme...

INTRODUCTION The study 'Mental healthcare provision for adults with intellectual disability and a mental disorder' (MEMENTA) is a cross-sectional epidemiological study carried out in three different regions of Germany. Its main aim is to assess the prevalence of mental disorders in adults with intellectual disability (ID) as well as quality of mental healthcare for this population. METHODS AN...

Antlion larvae that construct conical pits to capture prey may strongly affect foraging of ants and other arthropods, yet are usually abundant only in sheltered microhabitats. Larval antlion (Myrmeleon crudelisWalker) densities increased in exposed areas in central Texas in late summer and early autumnof 1998, presumably because of extended dry conditions. I conducted a study to quantify larval...

Cats have been shown to provide the only known reservoir of Bartonella henselae, the causative agent of cat scratch disease. To determine the prevalence of Bartonella bacteremia and antibodies in Dutch cats, blood samples from 113 cats from shelters (sheltered cats), 50 pet cats, and 25 specific-pathogen-free (SPF) cats were analyzed. Culture and subsequent PCR-restriction fragment length polym...
