This study was carried out to assess the habitat partitioning mechanisms of the two species around Lake Naivasha area. The charactretistics of habitats used by seven groups of each species were studied along the shorelines of lakes Naivasha and Oloiden. The two species differed significantly in the habitat characteristics. Arrow-marked Babbler is restricted to shorelines with dense tree and ground vegetation cover while Black-lored Babbler occupies open areas with sparsely distributed small trees and short ground vegetation cover. Observations on the feeding habits and social behaviours of the two species are also discussed.展开更多

Image oil painting is not just a simple art genre and style, it is a western oil painting the foreign art in the Chinese culturalenvironment to generate the types of oil painting is a kind of Chinese national culture characteristic of painting art for the purpose of art topresent true feelings and true feelings should be created by the artist’s technique, form, style, texture effects such as external factors. And manyof the current oil painting art works are showing the true feelings, because of the wrong style, texture and other external factors as the purpose ofart. Master of art means the long-term growth path is essentially in express their true feelings, and to form the style need to constantly supplementand perfect process. We provide the novel perspective on the corresponding issues that will be meaningful and important.展开更多

And in the literati paintings, Ni Zan＇s paintings are the most representative. The application of the pen and ink in his works is concise and thinly scattered, and the artistic conception is cold and desolate. In this paper, with ＂Map of a fishing village in an autumn sunny day after the rain＂ as an example, the author analyzes Ni Zan＇s painting style and the causes of its formation.展开更多

Rossetti＇s paintings, Elizabeth Siddal appears as a model. In real life, they formed a married couple, and the relatonship was not as idealistic as it might have been, between a muse-figure and an artist. After Elizabeth＇s death, Rossetti seemed to have been preoccupied with the ＂Lilith＂ theme in his painting and poetry and somehow he could not free himself from the haunting memory of the ＂wronged wife＂, the muse. This often found manifestation in his portrayal of the ＂femme fatale＂ images. Applying psychoanalysis to art-criticism and literary appreciation, this paper is an attempt to explore the relationship between a model and an artist, which both psychologically and aesthetically, seemed to be working beyond the former＇s death. Through a detailed analysis of the ＂Lilith＂ image in D. G. Rossetti＇s art, this paper has shown the coplexities of the artist＇s agony and anxiety over the image of a muse, a homely beloved--turned into a threatening ＂femme fatale＂, now distant, unknown, frightening yet fascinating, and mystified by death.展开更多
