Adaptive settlement in sedge warblers Acrocephalus schoenobaenus—focus on the scale of individuals
Breeding site selection can be linked to population dynamics through pre-emptive site selection, by which an individual selects the best (in terms of fitness) available site, preventing others from sharing it. We examined the pattern of territorial settlement and its fitness consequences during a study of sedge warblers Acrocephalus schoenobaenus inhabiting two study plots in the Nida Wetlands ...
متن کاملMolecular characterization of putative Hepatozoon sp. from the sedge warbler (Acrocephalus schoenobaenus).
We characterized partial sequences of 18S rDNA from sedge warblers infected with a parasite described previously as Hepatozoon kabeeni. Prevalence was 47% in sampled birds.We detected 3 parasite haplotypes in 62 sequenced samples from infected animals. In phylogenetic analyses, 2 of the putative Hepatozoon haplotypes closely resembled Lankesterella minima and L. valsainensis. The third haplotyp...
متن کاملPectoral muscle identification in mammograms
In most of the approaches of computer-aided detection of breast cancer, one of the preprocessing steps applied to the mammogram is the removal/suppression of pectoral muscle, as its presence within the mammogram may adversely affect the outcome of cancer detection processes. Through this study, we propose an efficient automatic method using the watershed transformation for identifying the pecto...
متن کاملAutomatic Identification and Elimination of Pectoral Muscle in Digital Mammograms
Computer aided detection/diagnosis aims at assisting radiologist in the analysis of digital mammograms. Digital mammogram has emerged as the most popular screening technique for early detection of breast cancer and other abnormalities in human breast tissue. The pectoral muscle represents a predominant density region in most mammograms and can affect/bias the results of image processing methods...
متن کاملBlood parasite infestation and the leukocyte profiles in adult and immature reed warblers (Acrocephalus scirpaceus) and sedge warblers (Acrocephalus schoenobaenus) during autumn migration
Haemoparasites prevalence in birds can vary among species, age and sex groups and ecological conditions. To comprehend the host–parasite assemblages, it is important to investigate physiological mechanisms underlying the interactions in wild bird species. Here, using blood smears we investigated how leukocyte profiles in reed warblers (Acrocephalus scirpaceus) and sedge warblers (Acrocephalus s...
