“…Reef sounds show promise for reef orientation (14,16,42,43), but we still need to know how far the acoustic reef signal extends above the noise or how it relates to the hearing frequency range of these fishes (44); it may be limited to relatively short distances (Ϸ1 km) (25). Superficial lateral line is useful for rheotactic responses (45,46), particularly in shear layers near solid surfaces and among water masses. However, although directional per se, none of these acoustic and hydrodynamic senses would allow animals suspended in the water column without external frame of reference to select favorable currents.…”

Many marine fish and invertebrates show a dual life history where settled adults produce dispersing larvae. The planktonic nature of the early larval stages suggests a passive dispersal model where ocean currents would quickly cause panmixis over large spatial scales and prevent isolation of populations, a prerequisite for speciation. However, high biodiversity and species abundance in coral reefs contradict this panmixis hypothesis. Although ocean currents are a major force in larval dispersal, recent studies show far greater retention than predicted by advection models. We investigated the role of animal behavior in retention and homing of coral reef fish larvae resulting in two important discoveries: (i) Settling larvae are capable of olfactory discrimination and prefer the odor of their home reef, thereby demonstrating to us that nearby reefs smell different. (ii) Whereas one species showed panmixis as predicted from our advection model, another species showed significant genetic population substructure suggestive of strong homing. Thus, the smell of reefs could allow larvae to choose currents that return them to reefs in general and natal reefs in particular. As a consequence, reef populations can develop genetic differences that might lead to reproductive isolation.coral reef ͉ olfaction ͉ population genetics

“…surrounding river banks), unless they are a benthic fish and in constant contact with the river bed. Thus, when deprived of visual cues, midwater fish may need to alter their behavior so that they are periodically in contact with the substrate to provide a (tactile) external frame of reference, as suggested previously (Lyon, 1904;Baker and Montgomery, 1999a). The effect of these fundamental differences in sensory input on behavioral output remains largely undocumented, except in the context of obstacle entrainment behaviors (Sutterlin and Waddy, 1975;Liao et al, 2003;Montgomery et al, 2003;Przybilla et al, 2010), which have a rheotactic component.…”

“…Optic flow cues appear to be sufficient for many species (Lyon, 1904), but not necessary, as rheotaxis persists in the absence of visual cues in species like the blind cavefish (Montgomery et al, 1997;Baker and Montgomery, 1999b). Nonvisual cues implicated in rheotaxis include tactile (Lyon, 1904;Baker and Montgomery, 1999a;Baker and Montgomery, 1999b), vestibular (Pavlov and Tjurjukov, 1993) and lateral line (Montgomery et al, 1997;Baker and Montgomery, 1999a;Baker and Montgomery, 1999b) cues. In the absence of lateral line cues, substantial reduction in rheotactic performance (to chance levels) has been observed in blind cavefish and several other species, but only at flow speeds less than ~5cms -1 [~1fish body length (BL)s -1 ] (Montgomery et al, 1997).…”

“…Typically reported is the instantaneous proportion of fish (usually in a group of four or five fish) that are heading within some angular criterion (e.g. ±45deg) of upstream (Pavlov and Tjurjukov, 1993;Montgomery et al, 1997;Baker and Montgomery, 1999a;Baker and Montgomery, 1999b). Unfortunately, the various angular criteria applied in these prior studies appear to be arbitrarily selected and they vary widely (from ±20 to ±90deg of upstream).…”

“…In the near field, vision and the lateral line system are of primary importance (Giske et al, 1998). The mechanosensory lateral line is used to monitor the local hydrodynamic environment, and is sensitive to water velocity and thus important for rheotaxis (Montgomery et al, 1997;Baker and Montgomery, 1999) and the acceleration component of oscillatory water flow (Montgomery et al, 1997;. Studies designed to identify the relative roles of vision and the lateral line system have often relied on experimental manipulation of the fish, e.g.…”

One "2020 vision" for fluvial geomorphology is that it sits alongside stream ecology and hydraulic engineering as a key element of an integrated, interdisciplinary river science. A challenge to this vision is that scientists from these three communities may approach problems from different perspectives with different questions and have different methodological outlooks. Refining interdisciplinary methodology is important in this context, but raises a number of issues for geomorphologists, ecologists and engineers alike. In particular, we believe that it is important that there is greater dialogue about the nature of mutually-valued questions and the adoption of mutually-acceptable methods. As a contribution to this dialogue we examine the benefits and challenges of using physical experimentation in flume laboratories to ask interdisciplinary questions. Working in this arena presents the same challenges that experimental geomorphologists and engineers are familiar with (scaling up results, technical difficulties, realism) and some new ones including recognising the importance of biological processes, identifying hydraulically meaningful biological groups, accommodating the singular behaviour of individuals, understanding biological as well as physical stimuli, and the husbandry and welfare of live organisms. These issues are illustrated using two examples from flume experiments designed (1) to understand how the movement behaviours of aquatic insects through the near-bed flow field of gravelly river beds may allow them to survive flood events, and (2) how an understanding of the way in which fish behaviours and swimming capability are affected by flow conditions around artificial structures can lead to the design of effective fish passages. In each case, an interdisciplinary approach has been of substantial mutual benefit and led to greater insights than discipline-specific work would have produced. Looking forward to 2020, several key challenges for experimentalists working on the interface of fluvial geomorphology, stream ecology and hydraulic engineering are identified.3
