This study deals with the transport behavior of the coarse-sediment at Masudagawa flood mitigation dam (FMD), Japan. Radio frequency identification system (RFID) was used to trace the displacement of the IC tagged particles following major flood events since June 2011. Through this, the relationship between recovery rate of the tagged particles and distribution of shear stress over the FMD bed ...

Skeletal characteristics vary among populations; therefore each population should have specific standards to optimize the accuracy of identification. Although many bones of skeleton present size related sexual differences, those of the hip bone usually displayed marked differences in morphology independent of size due to different reproductive functions mainly influenced by sex hormones. The di...

For centuries, biologists have asked "why are there so many species, and why do we see such magnificent biological diversity?" This dissertation addresses this question by examining sexual size and shape dimorphism hummingbird bills at both a micro and macroevolutionary scale. Specifically, I quantify sexual size and shape dimorphism of bill morphology of 269 species of hummingbirds and begin w...

In the Asellota, sexual dimorphism is often characterized by males that show pronounced morphological differences after the final moult compared to females but also to sub-adult males. Such a sexual dimorphism may strongly complicate allocation of these terminal males to conspecifics. Consequently, we regard it to be a likely explanation for why in 50% of the described species of the family Mac...

Previous experiments based on a masked-priming paradigm revealed robust morphological priming effects induced by two derivational morphemes in Hebrew: the root and the verbal pattern. However, considering the special characteristics of the masked-priming paradigm, the possible contributions of phonological and/or semantic factors to these morphological effects could not be firmly assessed. In t...

background : tropical rat mite ( ornithonyssus bacoti ) is reported from many parts of the world and is considered important in transmitting rickettsial pathogens. there have been scanty reports on prevalence of this parasite from india. following a recent report of o. bacoti infestation in a laboratory mice colony from nilgiris, tamil nadu, in­dia, attempts were made to detect the parasite in ...

raw cane sugar is one of the most important product in the sugar industry and is the main raw material for the white sugar production. morphological and physical properties of this product might influence the final white sugar. for instance, the behavior during centrifugation, transport and storage is related to the characteristics of these crystals. the object of this study was to determine th...

1. The female-limited colour polymorphic damselfly Ischnura elegans has proven to be an interesting study organism both as an example of female sexual polymorphism, and in the context of the evolution of colour polymorphism. The study of colour polymorphism can also have broader applications as a model of speciation processes. 2. Previous research suggests that there exist correlations between ...

New Caledonian Crows Corvus moneduloides are known to be extraordinary tool makers and users, but little is known of other aspects of their biology. Here, we report recent field observations of their behaviour and ecology, along with measurements of 19 morphological traits and two flight performance parameters taken from 22 captured Crows. These measurements showed that the Crows were sexually ...

sooty blotch and flyspeck occur on fruit surfaces and result in economic losses due to less attractive appearance. sooty blotch fungi form dark mycelial mats whereas flyspeck fungal agents are well characterized with black, sclerotium-like bodies on fruit surface. whilst more than 60 species have been reported in association with these two fungal diseases, thus far they have not been studied in...
