“…So, unlike iron the direct relationship to land use is not with forest cover, but with something else. Others have observed that both urban development and agricultural land use impact concentration of nutrients in a positive manner (Booth & Reinelt, 1993;Faulkner, 2004). However, some studies have indicated that urbanization does not significantly impact concentrations of either nitrates or phosphates (Hickman & Fischer, 2008;O Driscoll et al, 2010).…”

Past studies in the Baton Rouge, Louisiana area considered streamwater quality during storm events but ignored water quality during low flow periods. This study includes determination of streamwater quality during low flow time periods for none watersheds in East Baton Rouge Parish, Louisiana. These samples were collected during dry-low flow periods as indicated by water levels at USGS stream gauging sites for each stream. Chemical analysis for ions was completed using colorimeters and gravimetric analysis for total dissolved solids (TDS) and total suspended solids (TSS). Land use appears to impact concentrations of ions, TDS and TSS in a variety of ways during periods of low flow. The two most rural watersheds, which are mainly underdeveloped, have higher concentrations of Fe and Mn. By contrast the three most urban watersheds, that are mainly commercial, industrial or residential, have higher concentrations of Si, SO4 and TDS.

“…Sin embargo, aun cuando las áreas de reproducción estén protegidas, durante esta etapa las poblaciones pueden ser más sensibles a sufrir una declinación rápida, ya que se concentran en colonias grandes y en ecosistemas tan frágiles como los humedales, que pueden ser contaminados y fragmentados con facilidad (Faulkner, 2004). Para México en particular, los humedales se encuentran entre los ecosistemas más afectados por las actividades del hombre, tanto de manera directa como indirecta (Lara et al, 2008).…”

Temporal variation in spatial distribution by age of Phoenicopterus ruber (Phoenicopteriformes: Phoenicopteridae) in the wetlands of Yucatán, Mexico. The Caribbean Flamingo (Phoenicopterus ruber) in Mexico is distributed throughout the complex of lagoons in coastal wetlands of the Yucatan Peninsula. The species shows a tendency toward differential use of areas between juveniles and adults at different stages of their life cycle, and in different seasons. The aim of this study was to determine the most important areas where flamingos are distributed in Yucatan wetlands, and to describe temporal variations according to age and stages of their life cycle. For this, we used the records of ringed individuals sighted during the period 2010-2015. The areas with the largest numbers of individuals, by stage and season, were identified. Flamingos were recorded in 39 different areas of 43 sampled. In general, the sites with the largest number of records were Isla La Angostura and Punta Mecoh. To both juveniles and adults, areas with higher occupancy rates differed by age between the different stages of the life cycle and seasons. In the Charca Salinera Chel and Isla La Angostura ringed flamingos of almost all ages were recorded. Although already described areas (Celestún, Ría Lagartos) are certainly important, new sites hosting considerable populations at some stage of this species life cycle were detected (e.g. Humedal Progreso; Salamandra, Laguna Rosada; Xcambo). These new sites should be given more attention and important security measures and protection are recommended to all of them. It is necessary to seek new support sources for studies that determine the flamingo population's status in difficult access areas for which little information is available. Rev. Biol.

“…In the meantime, southwestern China experienced rapid urbanization, characterized by extensive urban sprawl, rural-urban migration, and increased Industry and Service shares of GDP (Table 2). It is generally believed that urbanization not only causes environmental problems, such as climate change and pollution (Faulkner, 2004;Grimm et al, 2008;McDonald, 2008;Shen et al, 2008), but also leads to invasion of exotic species and loss of biodiversity (Nagendra et al, 2014). However, urbanization can help increase the soil conservation by reducing soil disturbance from agricultural activities (especially on steep slopes) with the increasing share of Industry and Service (Grau and Aide, 2007;Ricardo and Aide, 2008).…”

Changes in ecosystem service of soil conservation between 2000 and 2010 and its driving factors in southwestern China

Human activities significantly alter ecosystems and their services; however, quantifying the impact of human activities on ecosystems has been a great challenge in ecosystem management. We used the Universal Soil Loss Equation and county-level socioeconomic data to assess the changes in the ecosystem service of soil conservation between 2000 and 2010, and to analyze its spatial characteristics and driving factors in the southwestern China. The results showed that cropland in the southwestern China decreased by 3.74%, while urban land, forest, and grassland areas increased by 46.78%, 0.86%, and 1.12%, respectively. The soil conservation increased by 1.88 × 10 11 kg, with deterioration only in some local areas. The improved and the degraded areas accounted for 6.41% and 2.44% of the total land area, respectively. Implementation of the Sloping Land Conversion Program and urbanization explained 57.80% and 23.90% of the variation in the soil conservation change, respectively, and were found to be the main factors enhancing soil conservation. The 2008 Wenchuan earthquake was one of the factors that led to the degradation of soil conservation. Furthermore, industrial adjustment, by increasing shares of Industry and Service and reducing those of Agriculture, has also promoted soil conservation. Our results quantitatively showed and emphasized the contributions to soil conservation improvement made by implementing ecological restoration programs and promoting urbanization. Consequently, these results provide basic information to improve our understanding of the effects of ecological restoration programs, and help guide future sustainable urban development and regional industrial restructuring.
