“…Besides, different water facilities for agricultural use are known to provide habitat for vertebrates such as waterbirds, amphibians and fish (Hazell et al 2001;Tourenq et al 2001) as well as for invertebrates (Gastropoda, Odonata, Coleoptera) and aquatic plants (Oertli et al 2002) and may be important for biodiversity conservation. Bird assemblages may be used as bio-indicators of water management (Paillison et al 2002) and waterbirds may also play an important role as mobile links in the conservation of the biodiversity of wetlands Lundberg and Moberg 2003).…”

Abstract. The growth of inter-basin water transfers and the development of new irrigation facilities in southeastern Spain are responsible for a variety of ecological impacts. In spite of this, the construction of artificial ponds to keep water for intensive agriculture may also provide new habitats for breeding waterbirds. We counted waterbirds during the breeding season in artificial ponds that had been built up using different materials and measured their abiotic and biotic attributes. We found that ponds were used as breeding and foraging habitat by 22 different waterbird species and breeding numbers of a few of them seemed to be larger in these artificial facilities than in nearby natural and semi-natural wetlands. Abundance and richness of breeding waterbirds was influenced by construction materials. Ponds constructed with low density polyethylene and covered with sand and stones held more species and their numbers were higher than those constructed with other plastic materials. The presence of emergent and submerged vegetation as well as abiotic attributes, such as pond size, accounted for most of the deviance when modelling richness and species abundance.

“…The presence of waterbirds in these lakes is dependent on resource availability in adjacent and distant (regional) wetlands. The socioecological changes in the lakes need to be constantly monitored in order to understand factors driving waterbird species diversity and abundance in the wetlands and to inform management decisions (Paillisson et al 2002).…”

“…Waterbird community dynamics are complex and are influenced by many natural and anthropogenic factors. Natural dynamics of waterbird populations are mainly driven by rainfall or water availability, which influence the physical structure of habitats and determine resource availability and accessibility (Paillisson et al 2002). Other drivers of waterbird community composition and abundance include bird biology (migration, breeding and moulting) and anthropogenic influences, such as hunting, water extraction for industrial and domestic purposes, and agricultural practices (Caziani et al 2001, van Niekerk 2010.…”

The spatial and temporal structures of waterbird communities are dynamic and complex with many driving factors. We used long-term waterbird census data at two lakes in Zimbabwe to explore the ecological and anthropogenic drivers of waterbird community composition and abundance. Ecological drivers predicted to influence waterbird communities include rainfall quantity and distribution, waterbird movement, breeding and moulting; anthropogenic drivers include activities such as fishing and agriculture. Results suggest that seasonal variations in resource availability influenced the waterbird community composition and abundance, as did movements at local, regional, and intercontinental scales. Bird numbers in the two perennial lakes experienced large changes in structure during two droughts. We also used the study as a baseline for considering the risk of spread of avian influenza virus (AIV) spread in waterbird communities in Zimbabwean lakes, which is likely to be higher in dry seasons and during drought years when waterbird abundance is high. Our study emphasises the importance of long-term ecological data in understanding crucial aspects of biodiversity conservation as well as pathogen dynamics in wild waterbird communities, with important management implications.

“…Wetland birds are sensitive to fluctuating WL, natural or anthropogenic, which can affect their habitat for foraging, nesting, and predator avoidance [14] [15]. The common loon (Gavia immer), a symbol of the northern wilderness, is a recognized indicator of wetland ecosystem health because of its high trophic position, limited dispersal ability, and slow replacement rate [16].…”

Rule curves dictating target water levels for management have been implemented in several water bodies in North America over the last 70 years or more. Anthropogenic alterations of water levels are known to affect several components of wetland ecosystems. Evaluating the influence of rule curves on biological components with simple performance indicators could help harmonize water level management with wetland integrity. We assessed the potential of using the probability of common loon nest viability as a performance indicator of long-term impacts of rule curves on nesting wetland birds. We analyzed the outcome of rule curves on the probability of loon nest viability in Rainy Lake and Namakan Reservoir, 2 regulated water bodies located along the Ontario-Minnesota border. The analysis was focused on 4 hydrological time series between 1950 and 2013: 2 sets of time series simulating rule curves used to manage the water bodies in the past decades (referred to as the 1970RC and 2000RC), one of the historical measured water levels, and one of computed natural water levels. The probability of loon nest viability under the 1970RC was 2× higher than under natural conditions in both water bodies. The probability was also 2× higher under the 2000RC than under the 1970RC in the Namakan Reservoir but not in Rainy Lake. The rule curves generally improved conditions for nesting loons in both water bodies. The presented performance indicator can be used to evaluate future rule curves before they are implemented in the Rainy-Namakan or other similar systems.
