“…Total capture expressed as the number of specimens before (1991-1994) and after (1999-2003) (Ward & Stanford, 1983) states that, in the case of dams located in lower reaches, the biotic diversity should increase, essentially because of an increase in the photosynthesis-to-respiration ratio. In some cases fish species richness was not altered by the presence of the dam (Travnichek & Maceina, 1994;Goure`ne et al, 1999). However, in many other situations a decrease in species richness has been evidencied (Garcia de Jalon & Camargo, 1994;Gowacki & Penczak, 2000;Quinn & Kwak, 2003;Bernacsek, 1984;Me´rona & Albert, 1999;.…”

“…In many cases, a decrease in species richness was observed either in temperate regions (Garcia de Jalon & Camargo, 1994;Gowacki & Penczak, 2000;Quinn & Kwak, 2003) or in tropical ones (Bernacsek, 1984;Me´rona & Albert, 1999;. Conversely, although fish community structure is very often deeply modified, there are situations where a reduction of fish diversity is not evidenced (Travnichek & Maceina, 1994;Goure`ne et al, 1999).…”

Dams are expected to decrease fish diversity because they deeply alter downstream environment. However, such decline has not been consistently observed although profound modifications in the structure and/or composition of fish communities were generally recorded, and were linked to modifications of the downstream environment. In this work we analyze data from observations made before and almost 10 years after the completion of a hydroelectric dam in the neotropics. We monitored fish diversity below that dam and compared the taxonomic and functional structures of the samples between the pre-and post-dam periods. A significant decrease in species richness was evidenced. Taxonomic and trophic structures were significantly different between the two periods. Conversely, the functional structure of samples based on reproductive traits did not change significantly after the damming. Concerning feeding habits, a large increase in relative abundance of detritivores and a parallel decrease of fish species feeding on terrestrial food sources were observed in samples taken 6-9 years after closure of the dam as compared with samples taken before the dam.

“…The monitoring effort employed a good study design, effectiveness and validation monitoring, pre-and post-change monitoring, and long-term implementation. Within 5-7 years, this work yielded valuable findings about the response of warm water fish community to the initiation of a minimum-flow release downstream from a hydroelectric dam (Travnichek and Maceina, 1994;Travnichek et al, 1995;Bowen, 1998). The monitoring and related analyses continued to yield valuable information and revised hypotheses for further investigation of changes in flow regulation patterns .…”

“…Possibly the best examples of the application of the principles outlined in this paper are the works of Travnichek and Maceina (1994); Bain et al (1988); Bowen (1998) on the response of warm water fish communities to changes in flow management of the Tallapoosa River (MAD: 133 m 3 s À1 ) downstream of Thurlow Dam, USA. The process followed in this work included the development of a conceptual model, key questions and hypotheses (Bain and Boltz, 1989); use of reference (control) streams; careful selection of response metrics, measurement methods and scales (Bain and Finn, 1982;Bain et al, 1988).…”

“…Although many new flow regimes have been adopted by formal or informal rules and regulations, there have been few long term (i.e. greater than 2-3 years) monitoring studies designed to detect the response of aquatic species to these new flows (MacDonnell et al, 1989;Travnichek and Maceina, 1994;Travnichek et al, 1995;Propst et al, 2000;Vinson, 2001).…”

The conclusions of numerous stream restoration assessments all around the world are extremely clear and convergent: there has been insufficient appropriate monitoring to improve general knowledge and expertise. In the specialized field of instream flow alterations, we consider that there are several opportunities comparable to full-size experiments. Hundreds of water management decisions related to instream flow releases have been made by government agencies, native peoples, and non-governmental organizations around the world. These decisions are based on different methods and assumptions and many flow regimes have been adopted by formal or informal rules and regulations. Although, there have been significant advances in analytical capabilities, there has been very little validation monitoring of actual outcomes or research related to the response of aquatic dependent species to new flow regimes. In order to be able to detect these kinds of responses and to better guide decision, a general design template is proposed. The main steps of this template are described and discussed, in terms of objectives, hypotheses, variables, time scale, data management, and information, in the spirit of adaptive management. The adoption of such a framework is not always easy, due to differing interests of actors for the results, regarding the duration of monitoring, nature of funding and differential timetables between facilities managers and technicians. Nevertheless, implementation of such a framework could help researchers and practitioners to coordinate and federate their efforts to improve the general knowledge of the links between the habitat dynamics and biological aquatic responses.
