We used a monospecific polyclonal antiserum against mitochondrial carbonic anhydrase (CA V) from rat liver to study tissue localization of this new member of the carbonic anhydrase gene family. Strong granular immunostaining reaction of CA V was observed in hepatocytes, myocardium, and in certain populations of skeletal muscle fibers. This is the first time that mitochondrial carbonic anhydrase is described in cardiac tissue of rat or any other species. Different epithelial cells revealed very heterogeneous staining reaction, suggesting that mitochondria are a heterogeneous population with respect to their CA V content. Many cells in different glandular epithelia did not show any CA V, whereas some cells, such as gastric parietal cells, were intensely stained with CA V antibodies. No systematic co-expression of CA V with CA I, CA II, or CA III was observed, although the distribution of CA V in skeletal muscle was somewhat similar to that of CA III. Connective tissue cells such as fibroblasts, chondroblasts, and osteoblasts were negative.

Abstract The Ulva prolifera green tides in the Yellow Sea, China, which have been occurring since 2007, are a serious environmental problem attracting worldwide attention. Despite extensive research, the outbreak mechanisms have not been fully understood. Comprehensive analysis of anthropogenic and natural biotic and abiotic factors reveals that human activities, regional physicochemical conditions and algal physiological characteristics as well as ocean warming and biological interactions (with microorganism or other macroalgae) are closely related to the occurrence of green tides. Dynamics of these factors and their interactions could explain why green tides suddenly occurred in 2007 and decreased abruptly in 2017. Moreover, the consequence of green tides is serious. The decay of macroalgal biomass could result in hypoxia and acidification, possibly induce red tide and even have a long-lasting impact on coastal carbon cycles and the ecosystem. Accordingly, corresponding countermeasures have been proposed in our study for future reference in ecosystem management strategies and sustainable development policy.

The world’s largest macroalgal blooms, Ulva prolifera, have appeared in the Yellow Sea every summer on different scales since 2007, causing great harm to the regional marine economy. In this study, the Normalized Difference of Vegetation Index (NDVI) index was used to extract the green tide of Ulva prolifera from MODIS images in the Yellow Sea in 2016–2018, to investigate its spatiotemporal patterns and to calculate its occurrence probability. Using the standard deviational ellipse (SDE), the morphological characteristics of the green tide, including directionality and regularity, were analyzed. The results showed that the largest distribution and coverage areas occurred in 2016, with 57,384 km2 and 2906 km2, respectively and that the total affected region during three years was 163,162 km2. The green tide drifted northward and died out near Qingdao, Shandong Province, which was found to be a high-risk region. The coast of Jiangsu Province was believed to be the source of Ulva prolifera, but it was probably not the only one. The regularity of the boundary shape of the distribution showed a change that was opposite to the variation of scale. Several sharp increases were found in the parameters of the SDE in all three years. In conclusion, the overall situation of Ulva prolifera was still severe in recent years, and the sea area near Qingdao became the worst hit area of the green tide event. It was also shown that the sea surface wind played an important part in its migration and morphological changes.
