Several fungal plant pathogens induce 'pseudoflowers' on their hosts to facilitate insect-mediated transmission of gametes and spores. When spores must be transmitted to host flowers to complete the fungal life cycle, we predict that pseudoflowers should evolve traits that mimic flowers and attract the most effective vectors in the flower-visiting community. We quantified insect visitation to f...
Previously only ten species of Hercostomus Loew were known to occur in Tibet, of which only two belong to the H. baishanzuensis group. Here the following six species of the H. baishanzuensis group are described as new to science: Hercostomus bisetus sp. nov., H. deltodontus sp. nov., H. flavus sp. nov., H. galonglaensis sp. nov., H. nuciformis sp. nov. and H. pailongensis sp. nov. A key to the ...
Background and purpose: Flies have a high diversity and are able to transmit many pathogens due to their adaptation and close relationship with humans. Therefore, this study was performed to identify the fauna of medically important flies in the city of Joybar in northern Iran. Materials and methods: This descriptive-analytical study was conducted twice a month in Juybar at selected sites, inc...
Studies on animal colour vision typically focus the chromatic aspect of colour, which is related to spectral distribution, and disregard achromatic aspect, intensity (“brightness”) a stimulus. Although component often most reliable for object recognition because it fairly context independent, may provide signal under specific conditions, example at night when light low. Here we make case import...
Due to the difficulty of tracking microbial dispersal, it is rarely possible disentangle relative importance dispersal and species sorting for community assembly. Here, we leverage a detailed multilevel network examine drivers bacterial assembly within flowers. We observed flower visitors 20 focal plant in coflowering Sierra Nevada, revealing 289 arthropods. also analyzed communities on flowers...
Two new species of Didicrum from Argentina are described and illustrated: Didicrum naimae and Didicrum letitiae, based on male and female specimens. Specimens were collected with Malaise traps located in Nahuel Huapi National Park, Patagonian region. Including the two new species of Didicrum, twelve are described from South America.
BACKGROUND AND AIMS Small populations of rare plant species are increasingly reported to have high levels of reproductive failure. The objective of this study was to understand the principal constraints on sexual reproduction in small fragmented populations of a rare clonal self-incompatible plant. METHODS The pollinator spectrum, diversity of flower colour, natural pollination and fruit-set ...
Background and Aim: Some medically important species of Muscidae and Fanniidae families are among synanthropic flies and can be seen in human habitats therefore they can be mechanical vectors of different pathogenic microorganisms. Identification and determination of species of these flies is essential for any control program planning. This study was conducted to determine the faunal diversity ...
