this study investigated the relationships between nutrients and chlorophyll, a concentration in the international alma gol wetland. chlorophyll a is the major photosynthetic pigment in lots of phytoplanktons and has been used as a trophy index in aquatic ecosystems. water samples were collected fortnightly from five stations in the wetland during summer and autumn. chlorophyll-a ranged between ...

1. Introduction The wetland is mostly distributed in the moist low temperature area at high latitudes. The wetland has the peat bog, which forms the accumulation of undecomposed plants. The important thing to notice is that the peat bog is similar to the aerial part of biomass in accumulating carbon. Since the amount of carbon cannot be ignored in the wetland, there is an urgent need to monitor...

This issue of Marine and Freshwater Research celebrates 50 years the Ramsar Convention on Wetlands, which was signed in 1971. It contains papers that describe development its implementation, including listing wetlands international importance maintenance their ecological character. The latter is a fundamental for wetland management as illustrated address range issues, impact climate change, app...

1. introduction wetlands are unique ecosystems that often appear on the sidelines of aquatic or terrestrial systems. they are among the most productive ecosystems on earth, the loss of which can lead to disastrous effects on the wild life and biodiversity. scientists believe that the destruction of wetlands results in the extinction of native species and their specific habitat. as the livelihoo...

The International Joint Commission has recently completed a five-year study (2000-2005) to review the operation of structures controlling the flows and levels of the Lake Ontario - St. Lawrence River system. In addition to addressing the multitude of stakeholder interests, the regulation plan review also considers environmental sustainability and integrity of wetlands and various ecosystem comp...

Although quarrying is often cited as a potential threat to wetland systems, there is a lack of relevant, quantitative case studies in the literature. The impact of pumped groundwater discharged from a quarry into a wetland area was assessed relative to reference conditions in an adjacent fen wetland that receives only natural runoff. Analysis of vegetation patterns at the quarry wetland site, u...

Background: The Gharana wetland conservation reserve (GWCR) is a semi-arid wetland adjacent to agricultural areas on the Indo-Pakistani border. Despite being declared an Important Bird Area (IBA) by Birdlife International, the occurrence and distribution of birds has not been well-documented in this area. Our aims were to systematically document the composition, relative abundance and feeding g...

The Conceptual Wetland Mitigation Plan for Phase II expansion to the John J. Briscoe Reservoir (Briscoe Reservoir) near Monroe, Georgia uses innovative approaches to restoring palustrine wetland functions to existing lacustrine habitats. This paper presents strategies for the design of forested and scrub-shrub wetland habitats in former wastewater treatment ponds and wetland design approach and...

BACKGROUND Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil mana...
