Key factors affecting metapopulation dynamics of animals include patch size, isolation, and patch quality. For wetlandassociated species, hydrology can affect patch availability, connectivity, and potentially habitat quality; and therefore drive metapopulation dynamics. Wetlands occurring on natural river floodplains typically have more dynamic hydrology than anthropogenic wetlands. Our overall...

Natural images and Photographs sometimes may contain stains or undesired objects covering significant portions of the images. Region completion is a method to fill in such significant portions of an image by using the information from the remaining area of the image. We propose a novel approach to achieve the completion in three steps. First, a spatial-range model is determined to establish the...

According to gap-phase dynamics theory, forests can be divided into four distinct patch types: gap patch (G), building patch (B), mature patch (M), and degeneration patch (D). Varying light conditions across patch types are one of the most important factors affecting the coexistence of vegetation. Mechanisms of coexistence can be understood through detailed knowledge of ecophysiological respons...

landscape characteristics and land use patterns of watershed demonstrate extension, distribution, density and abundance of human interference. these factors can affect water quality of adjacent aquatic systems within a watershed. land use changes have caused various environmental problems for zayandehroud river,turned it as a sink of pollutant. therefore this is investigated that how would land...

1. Patch area and proximity of patch edge can influence ecological processes across patchy landscapes and may interact with each other. Different patch sizes have different amounts of core habitat, potentially affecting animal abundances at the edge and middle of patches. In this study, we tested if edge effects varied with patch size. 2. Fish were sampled in 10 various-sized seagrass patches (...

The fusion between an endoscopic movie and a CT poses a special surface registration problem. The surface extracted from CT is complete and accurate, whereas the surface extracted from endoscopy suffers from serious missing patches and topology change. We propose a surface registration method, Thin Shell Demons, that is robust under these two situations. Motivated by Thirion’s Demons idea, the ...

This article presents the design of a miniaturized wearable patch antenna to be utilized for body area network (BAN) applications. To reduce size crown fractal geometry technique has been adopted, and which resulted in reduction 26.85%. Further, polyester cloth has used as substrate make proposed flexible one, suitable biomedical devices. The designed functions 2.45 GHz ISM band gain bandwidth ...

Urban green space is an important refuge of biodiversity in urban areas. Therefore, it is crucial to understand the relationship between the landscape pattern of green spaces and biodiversity to mitigate the negative effects of urbanization. In this study, we collected insects from 45 green patches in Beijing during July 2012 using suction sampling. The green patches were dominated by managed l...

Contraceptive patches have become a frequently used contraceptive method. We present a mathematical model that describes the serum concentration profiles of Norelgestromin (NGMN) and Ethinylestradiol (EE) released from the contraceptive patch Ortho Evra(®). We propose a simple one-compartment model based on pharmacokinetics data reported in previous studies. The model assumes a time-dependent r...
