“…Ephemeroptera, Plecoptera, and Trichoptera (EPT), which represent the highest taxon richness in freshwaters, 7) are very sensitive to pesticides. 8,9) Catchment urbanization in Georgia, USA, caused poor water quality in streams due to increased erosion of sediment, nutrients, and pesticide residues, resulting in less taxon diversity, with EPT being the most sensitive orders. 10) By examining the macroinvertebrate communities in six German streams, clean or contaminated with ten pesticides, the canonical correspondence and redundancy analyses showed that the variance in their communities, especially EPT and Diptera, was well described by the summation of toxic units, the pesticide concentration in water normalized to the acute LC 50 in Daphnia magna.…”

Aquatic insects having a high diversity are good biotic indicators for freshwater quality. Their larvae living in freshwater are sensitive to pesticides, and its impacts has been examined not only through laboratory toxicity studies using water and sediment exposure but also through higher-tier micro-/mesocosm studies and field monitoring. Many sophisticated statistical methods have been applied to assess the impacts of pesticides at levels from species to community, but their body burden has been studied much less, especially in relation to toxicity. We review the uptake, metabolism with relevant detoxifying enzymes, and depuration of pesticides in aquatic insect larvae, which determine their body burden and help to understand the toxicity profiles specific to each chemical class. We also discuss experimental conditions, environmental factors, and species sensitivity in relation to the bioconcentration/-accumulation and toxicity of pesticides.

“…As a consequence of agrochemical application, water quality and aquatic biodiversity have been compromised due to the destructuring of the physical and chemical environment and alteration of the natural dynamics of the biological communities (Goulart & Callisto, 2003). According to Biggs et al (2007), it is highly important to regulate the use of an agrochemical and its action against non-target organisms in the aquatic environment. However, specific data on the occurrence and population dynamics of aquatic organisms in agricultural areas are very limited.…”

“…At an individual (alpha, α) scale the richest ponds have a similar number of taxa to adjacent rivers (rivers are typically species rich but relatively uniform), but taxon poor ponds were among the most species deprived, highlighting the considerable heterogeneity in individual pond species richness . However, at a regional scale (gamma, γ) ponds have a significantly greater macroinvertebrate and macrophyte diversity than rivers, streams, and lakes and support a greater abundance of rare species than the other waterbody types in the UK Biggs et al, 2005;Biggs et al, 2007) and Europe (Davies et al, 2008b). Biggs et al (2005) bodies contributes to the high inter-patch species heterogeneity (beta-diversity) and regional diversity Davies et al, 2008b;Zealand and Jeffries, 2009).…”

“…Many have been polluted by diffuse nutrient loading from chemical and organic fertilizer and pesticide contamination Biggs et al, 2007), or are lost as a result of infilling or land drainage leading to an increase in the fragmentation of pond habitats (Boothby et al, 1995b;Boothby and Hull, 1997;Moss, 1998;Davies et al, 2009a).

Ponds are common and abundant features in nearly all landscapes typical of European lowland landscapes yet research on freshwater biodiversity has traditionally focussed on larger waterbodies such as lakes and rivers. This has led to an increased need to understand and quantify the biodiversity associated with pond habitats to better inform the active conservation and management of these small waterbodies. This thesis examines the aquatic macroinvertebrate biodiversity (alpha, beta and gamma) and conservation value of 95 ponds in Leicestershire, UK, across a variety of urban and rural landscape types and at a range of spatial scales. In addition, the relative importance of local (physicochemical and biological) and spatial (connectivity) variables in structuring macroinvertebrate communities within ponds is investigated. At a regional scale, the greatest macroinvertebrate biodiversity and conservation value was recorded within meadow ponds compared to urban, agricultural and forest ponds. Spatially, ponds were highly physically and biologically heterogeneous. Temporally (seasonally), invertebrate communities were most dissimilar in meadow and agricultural ponds but assemblages were similar in urban and forest ponds. In urban landscapes, park ponds supported a greater diversity of invertebrates than 'other' urban or garden ponds and typically had a greater conservation value. Garden ponds were the most taxon poor of those investigated. Perennial floodplain meadow ponds supported a greater biodiversity of invertebrates compared to ephemeral meadow ponds although conservation value was similar. Despite regular inundation from the River Soar, ephemeral ponds supported distinct communities compared to perennial meadow ponds. Aquatic macrophytes supported a higher diversity of taxa than other pond mesohabitats across all landscapes studied. Physicochemical factors were identified to be the dominant influence on macroinvertebrate assemblages although, a combination of local and spatial factors best explained the variation in community composition at a regional scale and for meadow ponds. Spatial factors were not identified to significantly influence urban pond communities. This study highlights the ecological importance and conservation value of ponds in rural and anthropogenically disturbed landscapes. Recognition of the significant contribution of ponds to freshwater biodiversity at regional and landscape scales is important for future conservation of pond habitats and will help focus and direct conservation strategies to where they are needed most.iv
