The pelicans are a charismatic group of large water birds, whose evolutionary relationships have been long debated. Here we use DNA sequence data from both mitochondrial and nuclear genes to derive a robust phylogeny of all the extant species. Our data rejects the widespread notion that pelicans can be divided into white- and brown-plumaged groups. Instead, we find that, in contrast to all prev...

Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred wh...

We report a boy with chronic central cyanosis since birth. He was otherwise asymptomatic with chocolate brown color of blood. Methemoglobinemia was suspected after exclusion of the cardiac and pulmonary diseases. Hereditary methemoglobinemia was considered by his clinical course. The simple bedside procedure could be performed to determine methemoglobinemia by vigorous shaking his blood with ox...

The current study evaluates consistency among three Normalized Difference Vegetation Index (NDVI) datasets, namely GIMMS, MODIS and SPOT, to characterize alpine vegetation dynamics (greening browning) across High Mountain Asia (HMA) in 2001–2015. utility of these datasets is explored evaluate the vegetation's variability at different spatial-temporal scales and, elevation, compare their spatial...

Alternaria brown spot is a serious disease in mandarins and mandarin hybrids. In this particular research, 9 Alterneria tolerant 2 susceptible mutant individuals obtained from series of vitro vivo studies were used. Endogenous indole acetic acid (IAA) zeatin hormone levels the noted before after inoculations order to determine hormonal variations during research. It was determined that endogeno...

In modern digital agricultural applications, automatic identification and diagnosis of plant diseases using artificial intelligence is becoming popular widespread. Deep learning a promising tool in pattern recognition machine it can be used to identify classify paddy rice. this study, 2 different rice diseases, including blast brown spot, were investigated the district İpsala province Edirne be...

Technological advances have made a major contribution to controlling plant diseases. One method for resolving issues with disease identification is the use of deep learning digital image processing. Tea leaf that requires fast and effective control. So, in this study, we adopted Convolutional Neural Network (CNN) architectures, namely ResNet-50 Inception V3, classify six types diseases attack l...
