Aquatic macrophytes are important components of wetland ecosystems, and studying them contributes to a better understanding of ecological succession in the Pantanal. The function and history of floating macrophytes on the shores of Lake Uberaba, located on the Paraguay River floodplain, were examined. A multitemporal analysis of Landsat satellite images in the years 1984-2015 was conducted. For the analysis, a land cover map was generated with three classes: water, aquatic macrophytes, and surroundings (undefined vegetation). The results revealed ~21.4% decrease in open water area of the lake over a period of 26 years (-4.7 km2/yr.). The expansion of vegetation helps explain the loss of open water and the recent shrinkage of Lake Uberaba. Macrophyte surface area along the lake margins grew by 1.4 km2/yr. Through ecological succession, the growth and decay of aquatic plants (r-strategists) along the lake shore likely provided the soil substrate needed for colonization by terrestrial plant assemblages (k-strategists). This hypothesis that we propose to describe the evolution of dynamic geomorphological processes in Lake Uberaba should be tested in other areas to verify its applicability to similar systems. |

The Rural Collective Actions are presented with the aim of facing and overcoming difficulties and particularities of the agricultural business, as well as obtaining gains and advantages, in an environment that suffers from constant transformations. This study investigates which reasons determine the choice of the Rural Collective Action model Rural Warehouse Condominium, under the perspective of the Theory of Logic of Collective Action. For this purpose, we conducted the Statistical Analysis, Multiple Correspondence and Correlation Analysis. The results indicate motivating factors for the rural model through Social, Logistics, Political, Economic, Management and Collective Action Logic variables, being of more significant burden: (i) smaller collective actions are easier to promote collective interest; (ii) rural producers work together to promote common interests; (iii) in a small collective group, individual efforts have a higher influence on results; and, (iv) the smaller is the collective group, the closer is the individual will be to achieving collective benefits. The correlation analysis shows stronger relationships between cost reduction with freight and cost reduction with transport (0.833); and, between the lack of financing lines for small and medium producers and the lack of financing lines for agricultural warehouse (0.741). |
