Occurrence and ecological notes on Rocinela signata (Isopoda, Flabellifera) off Brazil

This paper discuss the vertical and horizontal distribution of the marine isopod Rocinela signata Schiödte & Meinert, 1879, along Brazil. Published records and new data gathered in recent years were used. The species, widely distributed along Brazil, has its most southern limit of occurrence considerably extended to off State of Santa Catarina (27º08'S, 48º11'W) . It is typically a shelf species. So far it was recorded off Brazil at a maximum depth of 73 m, while particularly in southern Brazil at 53 m. The species has been collected free living on the bottom or as a fish parasite, and a few times has been reported attacking and sucking swimmers. Available data suggest any host specificity. R. signata seems a facultative and not an obligate fish parasite.

For over 130 years, the Atlantic Forest antwren Rhopias gularis (Spix, 1825) remained known in the Brazilian state of Rio Grande do Sul from 2 undated specimens collected by Hermann von Ihering at Taquara in the early 1880s. We located 1 couple plus 2 lone females along the border with Santa Catarina in the Josafaz stream valley, municipality of Mampituba, in October 2017 and January 2018. These records confirm the present-day occurrence of R. gularis in Rio Grande do Sul and establish a new southern limit of its distribution. We briefly discuss the validity of Ihering’s record and the historical occurrence of the species at Taquara.

Rapid Drop

An “explosive extratropical cyclone” is an atmospheric phenomenon that occurs when there is a very rapid drop in central atmospheric pressure. This phenomenon, with its characteristic of rapidly lowering the pressure in its interior, generates very intense winds and for this reason it is called explosive cyclone, bomb cyclone. With gusts recorded of 116 km/h, atmospheric phenomenon – “cyclone bomb” (CB) hit southern Brazil on June 30, the beginning of winter 2020, causing destruction in its influence over. One of the cities most affected was Chapecó, west of the state of Santa Catarina. The satellite images show that the CB generated a low pressure (976 mbar) inside it, generating two atmospheric currents that moved at high speed. In a northwest-southeast direction, Bolivia and Paraguay, crossing the states of Parana and Santa Catarina, and this draft that hit the south of Brazil, which caused the destruction of the affected states. Another moving to Argentina, southwest-northeast direction, due to high area of high pressure (1022 mbar). Both enhanced the phenomenon.

Abstract The aim of the present study was to investigate the occurrence of N. caninum associated with abortions of dairy cattle from Santa Catarina state, southern Brazil by using enzyme-linked immunosorbent assay (ELISA), immunohistochemistry (IHC), and polymerase chain reaction (PCR). Blood from dairy cows that aborted along with intrathoracic fluid and tissue samples (brain, heart, liver, and lung) from their fetuses were collected and used for serology; PCR, histopathological, and immunohistochemistry (IHC) evaluations were also conducted. Twenty-one cows (51.2%) out of 41, and eight fetuses (26.7%) out of 30 were ELISA (HerdCheck, IDEXX) positive for N. caninum. Dams > 36 months of age had a higher risk of being serum positive than younger animals. PCR and IHC revealed that 38.8% (14/36) and 25.0% (9/36) of the fetuses were positive for N. caninum, respectively for each of the tests. Seropositive cows had a higher frequency of fetuses that were also positive by either intrathoracic fluid, PCR, or IHC. In summary, the present study observed a high frequency of N. caninum in abortions from dairy cows from southern Brazil, with a higher N. caninum prevalence found in cows that were older than 36 months. In addition, serology, PCR, and IHC should be used all together for better diagnosis of neosporosis in cattle.

ABSTRACT The incidence of grapevine decline and dye back is quite severe in grapevine-growing regions of southern Brazil, especially in the Midwest of Santa Catarina State. Field studies on problematic areas identified the presence of the Brazilian ground pearl or margarodes (Eurhizococcus brasiliensis Hempel) and soil fungi (Cylindrocarpon, Fusarium and others) associated with the disease. Soil characteristics such as high clay content and poor aeration were associated with the problem. To evaluate the effect of pre-planting tillage in reducing the incidence of grapevine decline, an experiment was carried out with two rootstocks and three pre-planting tillage (regular plowing, drains, and ridges) in an area where high plant mortality had been previously observed. Pre-planting tillage with the use of ridges along the rows gave the best results with a drastic reduction in the decline incidence. The number of ground pearl cysts was unaffected by pre-planting tillage and did not relate with the incidence of decline and death of plants.

Vertical And Horizontal Distribution

The vertical and horizontal distribution of NPEOn and their metabolites of NP and NPEnC in the Upper Nansi Lake, North China were investigated using LC-MS and LC-MS/MS methods, sampling at three sites (St.1, St.2 and St.3) along the water flow direction. The total content of NPEOn (n=1–15) bound onto the sediment of this lake changed in the range of 60.7–631.5 μg/kg-dry with the horizontal flow direction and the vertical direction of the sediment cores with sediment thickness up to 35 cm. Compared to the presence levels of all detected NPEOn species, the content of NP was much higher, falling in 26.5–1,998.4 μg/kg-dry. A general increasing trend of the NP content along the water flow direction of this lake was revealed. NPEnC showed a roughly increasing trend from the upstream to the downstream, with the total concentrations being obviously lower than NPEOn and NP and falling in 2.13–23.1 μg/kg-dry. The short chain NPEOn dominant in NPEO mixtures in these sedimentary cores indicated that this lake received some effluents from STPs, and the sewage treatment ratio is relatively low in this area. Furthermore, the computed magnitudes of NPEO 1-2/NPEO1-15, NP/NPEO 1-15 and NPEC 1-10/NPEO 1-15 suggested that the non-oxidative hydrolytic transformation seemed to be a major process occurring within the sediment phase of Nansi Lake, while the oxidative hydrolytic transformation pathway was probably less involved.
