The lunar semidiurnal influence is already known for tidal rivers. The moon also influences inland rivers at a monthly scale through precipitation. We show that, for some non-tidal rivers, with special geological conditions, the lunar semidiurnal tidal oscillation can be detected. The moon has semidiurnal tidal influence on groundwater, which will then export it to streamflow. Long time series ...

A study was conducted on the length-weight relationship, condition factor and the sex ratio of 14,466 fish representing 46 species belonging to 28 genera from 16 families of economically important freshwater fishes inhabiting the 200 km length of Cross River inlands wetlands, Nigeria. Fish samples were collected with artisanal gears (gillnets, cast nets, seine nets) during January 2006 and Dece...

There are several freshwater systems associated to large rivers in South America, being the inland wetlands one of substantial significance from an environmental and ecological point of view. Largely sub-valued and unknown, the permanent-temporary flooded ecosystems related to the Parana River in Argentina and Paraguay must be studied in view to their conservation. In the particular case of the...

In the eastern U.S. Coastal Plain and Piedmont region, diverse inland wetlands (riverine, depressional, wet flats) have been impacted by or converted to agriculture. Farm Bill conservation practices that restore or enhance wetlands can return their ecological functions and services to the agricultural landscape. We review the extent of regional knowledge regarding the effectiveness of these con...

Inland saline wetlands are complex systems undergoing continuous changes in moisture and salinity and are especially vulnerable to human pressures. Remote sensing is helpful to identify vegetation change in semi-arid wetlands and to assess wetland degradation. Remote sensing-based monitoring requires identification of the spectral characteristics of soils and vegetation and their correspondence...

Background Bangladesh is basically a low lying flat land country, is endowed with enormous inland fishery resources which contribute a significant part of freshwater fish production. Inland fisheries in Bangladesh contain different types of water bodies’ character e.g. flowing rivers, beel—usually deeper depression in the floodplain, haor—extensive low lying areas comprising several perennial b...

As an important part of the global ecosystem, wetlands and their dynamics greatly influence regional eco-environment systems. To understand the distributions, change processes and temporal-spatial characteristics of the wetlands of the inland river basin in an arid region (Heihe River Basin, HRB), this paper employed multi-source remote sensing data to facilitate multi-temporal monitoring of th...

Intertidal wetlands are recognised for the provision of a range of valued ecosystem services. The two major categories of intertidal wetlands discussed in this contribution are saltmarshes and mangrove forests. Intertidal wetlands are under threat from a range of anthropogenic causes, some site-specific, others acting globally. Globally acting factors include climate change and its driving caus...

INTRODUCTION Wetlands are ecologically as well as economically important systems due to their high productivity, their nutrient (re)cycling capacities, and their prominent contribution to global greenhouse gas emissions. Being on the transition between terrestrial and—aquatic ecosystems, wetlands are buffers for terrestrial run off thereby preventing eutrophication of inland as well as coastal ...
