In Brazil, land use and occupation in environmentally vulnerable areas protected by law has been a recurring practice and difficult to combat. Permanent preservation areas (PPPs), especially those adjacent to the watercourses, are used by agricultural activities, causing land losses and soil degradation. The objective of this study was to assess the impact of soil use in the physical quality and emission of greenhouse gases (GHG) in PPPs of the Atlantic forest biome. The study was conducted in Haplic Cambisol (Inceptsol), located in marginal strips of vegetation (70 m) adjacent to the Ribeira de Iguape River, in Registro, a county in the South of São Paulo State, Brazil, There were identified and selected four kinds of land use in the experimental area: banana cultivation (BC), extensive pasture (EP) and native forest (NF). Physical and chemical soil analyses were carried out to assess bulk density, macro and microporosity and total porosity, total organic carbon (TOC), mean weight-diameter of soil (MWD), stability index (SI) and soil erodibility (SE). Soil analyzes were evaluated according to Embrapa (2011). The method used to capture GHG was the closed chamber. Subsequently, from GC Shimadzu® gas chromatograph model GC 2014, N2O and CO2 concentrations were determined by ECD (electron capture) detector, operating at 300°C, and CH4 concentrations by type detector FID (flame ionization). The results from this study showed that, BC area had an average annual loss of 10 times greater than EP, even with higher soil organic matter and structural stability. The values for CO2 and N2O emission were higher in EP, probably due to the type of vegetation, presence of animals, soil exposure to solar radiation and soil compaction by animal trampling. MN area had higher CH4 emission values, probably due to the humidity, favoring anaerobic respiration and greater presence and mineralization of soil organic matter. About soil erodibility and GHG emissions, in the BC area lowest rates of gas emissions found are due to the loss of soil physical properties related to soil structure, to the transport and eluviation of particles, and losses the chemical fertilizers in these areas.

The objectives of this study were to: (1) evaluate the feasibility of ultrasonic biomicroscopy (UBM) for imaging ovarian follicles in vivo in cows and heifers, (2) compare the transvaginal to the transrectal approach, (3) compare the number of follicles detected by UBM to conventional ultrasonography (US), and (4) identify cumulus-oocyte-complexes (COC) within follicles by UBM. Mature cows (n = 5) and peri-pubertal heifers (n = 5) were examined once using conventional B-mode US (Aloka 900) with a 7.5 MHz transrectal, and a 5 MHz transvaginal transducers. A second series of examinations was performed using UBM (Visualsonics Vevo 660) equipped with a 30 MHz transrectal and a 40 MHz transvaginal transducer. A three- to four-fold increase in the number of small follicles (<3 mm) was detected using the transvaginal approach with UBM compared to conventional US in both heifers (32.4 ± 4.24 compared to 7.2 ± 1.4; P < 0.0001) and cows (35.0 ± 13.8 compared to 10.7 ± 7.5; P = 0.0013). However, fewer follicles (all sizes combined) were detected using the transrectal approach with UBM compared to conventional US in both heifers (8.6 ± 5.6 compared to 17.6 ± 4.9; P = 0.02) and cows (5.3 ± 6.1 compared to 20.3 ± 7; P = 0.04). In heifers, COC-like structures were identified in 39 of 202 (19.3%) follicles examined. In conclusion, UBM using a transvaginal approach is feasible and may be used for in vivo assessment of early antral follicles as small as 0.4 mm, and COC within follicles. |
