Studies on Cladocera biodiversity in Brazilian freshwater ecosystems are intensifying. However, the fauna of some hydrographic regions is still poorly known. We investigated the richness and species composition of cladocerans in lakes of the Pantanal from the state of Mato Grosso (Paraguay hydrographic region), Brazil. In addition, we cataloged the known cladoceran species in each hydrographic region of the state. Occurrence data were obtained from the literature and samples collected from 50 lakes in the northern Pantanal. We recorded 120 cladoceran species from eight families in the state of Mato Grosso. The occurrence of these species was recorded in the Amazon and Paraguay hydrographic regions. We are unaware of studies on cladocerans conducted in the Tocantins-Araguaia hydrographic region. We reported 17 new records in the Pantanal samples (Paraguay hydrographic region). Overall, richness estimates reveal that 72.6% of the state's cladoceran fauna is already known, while for the Paraguay hydrographic region this estimate is 72.2%. In general, the cladocerans from the Amazon and Paraguay regions did not differ. Our findings allow us to infer the need for further studies in the different hydrographic regions found in Mato Grosso in order to improve the knowledge of cladoceran biodiversity. We suggest a greater sampling effort, particularly in the littoral zone of aquatic ecosystems in this state, which can harbor great biodiversity.

The Way

To solve the ecological deterioration problems of the medium and small reservoirs’ downstream areas caused by water interception, the ecological restoration technique for dam’s downstream area is studied in this paper. Based on the investigation and analysis of the current ecological environment of a medium and small reservoirs’ downstream area in Qingyuan county of Liaoning, the downstream minimum ecological flow, with which the ecological environment of downstream can connect to that of upstream, is calculated. In the way of drawing water above the dam and building underground dam, the minimum ecological flow for the ecological environment of the downstream area will be able to reach a level where the continuity of the ecological environment is maintained. Consequently the aquatic habitats and stream ecological environment of the dam’s downstream channel can be improved and recovered.

Ecological Treatment

Large-scale controlled planting of water hyacinth has become one of the most important measures of Dianchi Lake’s treatment in the “12th Five-Year Plan”. This paper firstly introduced the present situation of large-scale controlled planting of water hyacinth in Dianchi Lake. The water quality of Caohai and Waihai of Dianchi Lake were compared before and after the project of planting water hyacinth. This paper concluded that the effects of large-scale controlled planting of water hyacinth on the ecological restoration of Caohai lake were outstanding. The area of controlled planting could be spread among other water areas of Dianchi lake where is suitable for the growth of water hyacinth in the future, and water hyacinth will pay a greater role in the ecological treatment of Dianchi Lake.

Este artículo identifica las condiciones de vulnerabilidad y riesgo al cambio climático que presenta la ciudad de Pedernales (Ecuador) en relación con el agua. Caracteriza estas problemática en función de cuatro ejes: el estado de los recursos hídricos, las formas de ocupación sobre riberas, los mecanismos de circulación del agua y el sistema sociocultural de uso de este recurso. Luego describe cómo el enfoque de adaptación basado en un diseño urbano sensible al agua puede disminuir la vulnerabilidad que genera la contaminación de las riberas del principal río de la ciudad. A partir de esto se busca debatir los retos que para la agenda local implicaría la recuperación integral de riberas y ríos a través de procesos de restauración ecológica y mejoramiento paisajístico. Abstract This article identifies the conditions of vulnerability and risk to climate change presented by the city of Pedernales (Ecuador) in relation to water. It characterizes these problems according to four axes: the state of water resources, the forms of occupation on riverbanks, the mechanisms of water circulation, and the sociocultural system of use of this resource. Then he describes how the adaptation approach based on an urban design sensitive to water can reduce the vulnerability generated by pollution of the banks of the main river in the city. From this, it is sought to discuss the challenges that for the local agenda would imply the integral recovery of banks and rivers through processes of ecological restoration and landscape improvement.

Ecological restoration has become an important tool for mitigating and adapting to environmental degradation caused by global urbanization. However, current research has focused on single indicators and qualitative analysis, meaning that ecological restoration has not been effectively and comprehensively addressed. This study constructed a spatial priority identification system for ecological restoration, with landscape area, landscape structure and landscape function as the core indicators. The system has wide adaptability. In this work, the spatial classification of ecological degradation was performed by overlay analysis. The results showed the following: (1) In the Shanghai metropolitan area, the landscape quality showed a trend of degradation, with built-up areas encroaching on forests and cropland. (2) Ecological degradation in the suburbs was more severe than that in the urban center. Forests had the highest landscape area indicator (LAI) stability. Significant degradation of landscape structure indicators (LSIs) occurred when built-up area and cropland were transformed into forests. (3) Different types of ecological restoration had significant spatial distribution patterns. Through this identification system, this study aimed to help planners/managers of ecological restoration to recognize the changing patterns of regional landscape quality and its relationship with land cover. It ultimately provides a basis for the formulation of regional ecological objectives and spatial strategies.
