Summary1. Non-consumptive effects of predators are increasingly recognized as important drivers of community assembly and structure. Specifically, habitat selection responses to top predators during colonization and oviposition can lead to large differences in aquatic community structure, composition and diversity. 2. These differences among communities due to predators may develop as communities assemble, potentially altering the relative quality of predator vs. predator-free habitats through time. If so, community assembly would be expected to modify the subsequent behavioural responses of colonists to habitats containing top predators. Here, we test this hypothesis by manipulating community assembly and the presence of fish in experimental ponds and measuring their independent and combined effects on patterns of colonization by insects and amphibians. 3. Assembly modified habitat selection of dytscid beetles and hylid frogs by decreasing or even reversing avoidance of pools containing blue-spotted sunfish (Enneacanthus gloriosus). However, not all habitat selection responses to fish depended on assembly history. Hydrophilid beetles and mosquitoes avoided fish while chironomids were attracted to fish pools, regardless of assembly history. 4. Our results show that community assembly causes taxa-dependent feedbacks that can modify avoidance of habitats containing a top predator. Thus, non-consumptive effects of a top predator on community structure change as communities assemble and effects of competitors and other predators combine with the direct effects of top predators to shape colonization. 5. This work reinforces the importance of habitat selection for community assembly in aquatic systems, while illustrating the range of factors that may influence colonization rates and resulting community structure. Directly manipulating communities both during colonization and post-colonization is critical for elucidating how sequential processes interact to shape communities.

“…There are few empirical data to confirm that vertebrate predators of other vertebrates forage optimally or that they select the most vulnerable rather than the most available prey. Many data that are available come from studies of invertebrates or fish (Ebert 1991; Christensen & Persson 1993; Kohda 1994; Krause & Godin 1995; O’Keefe, Brewer & Dodson 1998; Snyder & Peterson 1999), many of which are laboratory‐based and may reflect behaviour in wild populations only poorly (Lima 1998). For terrestrial predators there are fewer studies (Scheel 1993), although many studies make inferences about prey choice rules from the ratio of prey killed to its abundance (Götmark & Post 1996; Tornberg 1997) or to factors that affect hunting success (Fitzgibbon 1990; Funston, Mills & Biggs 2001).…”

Summary1. Game theoretic models of how animals manage predation risk have begun to describe predator responses to prey behaviour relatively recently. This is partly because our understanding of how terrestrial predators select vertebrate prey is often limited to numerical and functional responses to measures of prey abundance. Prey vulnerability, however, may improve our understanding of predation because predators could maximize foraging success by selecting prey on this basis. 2. We tested the hypothesis that sparrowhawks ( Accipiter nisus L.), a typical generalist predator, hunt redshanks ( Tringa totanus L.), a favoured prey species on coastal shores, primarily on the basis of their vulnerability rather than their abundance. 3. Five direct measures or indicators of redshank behaviour predicted sparrowhawk attack success in a multipredictor statistical model and therefore serve as measures of redshank vulnerability. 4. These and other vulnerability measures influenced whether sparrowhawks decided to hunt redshanks on saltmarsh habitat. A model that included most of these measures predicted correctly whether sparrowhawks hunted redshanks (attack decision) 90% of the time and accounted for up to 75% of variation. Prey abundance accounted for no additional variation. 5. Thus the hunting behaviour of some predators can only be predicted well by several highly dynamic and interacting factors related to prey vulnerability. These results mean that, theoretically at least, the management of prey populations may sometimes be achieved best by manipulating prey vulnerability, rather than by culling their predators.

Centrarchid Fishes

The family Ccntrarchidae (Order: Perciformes) is one of the most diverse, widespread, and conspicuous fish families native to freshwater habitats of North America. Aniong endemic fish families of North America, only the North American catfish family (lctaluridae) has more species. The family name, Centrarchidae. refers to the anal fin spines of species in the family, and the common name. sunfishes, to the bright breeding colors displayed by males of some species in the family. Because of their diversity, wide distribution, and economic value, some of the earliest taxonomic descriptions and natural history observations on North American freshwater fishes focused on the centrarchids (e.g., Linnaeus 1758; Lacépède 1801; Rafinesque 1820; Abbott 1870).The family contains 34 extant species classified in eight genera, but morphological and genetic evidence suggests that additional, but currently unrecognized, diversity exists within most of the genera. The most diverse genus. Lepomis. the bream (or panfish) of anglers, is comprised of 13 extant species, but at least 8 of these show evidence of polytypy (e.g.. Bermingham and Avise 1986; Fox 1997;Harris 2005). The genus Micropterus, referred to collectively as black basses (Philipp and Ridgway 2002), contains eight extant species. but again, at least three species are polytypic (e.g., Stark and Echelle 1998;Kassler 2002;Miller 2005). The genera Anthloplites (rock basses). Enoeacaothus (banded sunfishes). and Poo,o.vis (crappies) contain four, three, and two extant species, respectively, and at least one species each of Ambloplites and Enneacaothus is polytypic (Koppelman 2000; T. Darden, South Carolina Department of Natural Resources, personal communication). The genera Acantha echos, Archoplites. and Centrorchos are monotypic. but populations of both Acantliarchus poniotis and Archoplites lolerruptus show geographical patterns of morphological divergence (Cashner ci (il. 1989;Moyle 2002).The natural range of extant centrarchids is confined primarily to warm, freshwater habitats in North America east of the western continental divide except for the Sacramento perch (A. interrupius). whose native range is west of the divide in the Central Valley of California (San Joaquin-Sacramento. Pajaro. Salinas river drainages. Moyle 2002). The northern natural continental limit of the family is occupied by members of Leponiis. Ainhiopliles, Poinoxis, and Microptertis in the St. Lawrence River. northern Great Lakes. and southwestern Hudson Bay drainages in eastern Canada (Scott and Ciossman 1973). The Rio Conchos (Rio Grande drainage) (Lepomis) and Rio Soto la Marina (Micmpterus. Miller and Smith 1986;Miller 2005) of northern Mexico delimit the southern continental limits of the native range of extant centrarchids. The Mississippi River Basin and, to a lesser extent, the Gulf and Atlantic Slope drainages harbor the most diverse assemblages of native centrarchids (Warren ci (il. 2000). The native ranges of Po,noxis and Lepomis largely coincide with that of Micropierus, but both exte...
