“…Empirical studies across a broad range of taxa have revealed that IG predators and IG prey typically show limited spatial overlap (Polis and McCormick 1987, Doncaster 1992, Durant 1998, Fedriani et al 2000, Raymond et al 2000, Sergio et al 2003. In some systems, such as the coral reef interaction web we examined, spatial segregation is achieved by differential use of habitat structure by predators and prey.…”

“…For example, some IGP theory predicts a trophic cascade where the shared prey benefits from the consumption of IG prey by IG predators, although this was not supported by a recent meta-analysis of empirical studies of intraguild predation in unstructured habitats (Janssen et al 2007). Of course, predators and prey frequently are not well mixed in nature (e.g., Fedriani et al 2000).…”

Abstract. The ability to forecast community dynamics requires, among other things, an understanding of indirect effects and nonlinearities in webs of interacting species, together with knowledge of how habitat structure mediates interactions. We explored these aspects for a coral reef system in Moorea, French Polynesia, involving intraguild predation where the shared damselfish prey ( juvenile yellowtail dascyllus Dascyllus flavicaudus) and two species of intraguild (IG) prey (the ambush predators arc-eye hawkfish Paracirrhites arcatus and redspotted coral crab Trapezia rufopunctata) shelter together in branching Pocilloporid corals for protection from mobile IG predators. Field experiments revealed that both IG prey had strong adverse effects on survivorship of juvenile damselfish, but that the dominant underlying process was competition for enemy-free space and not direct consumption. In this case, the combined effect of hawkfish and crabs did not result in either risk enhancement or risk reduction for the damselfish. Similarly, the combined influence of IG predators and IG prey on the shared prey also was indistinguishable from that expected from their independent effects. Habitat structure weakened the IG-prey-IG-predator interaction; IG prey were much stronger space competitors with damselfish than resource competitors with IG predators. As a consequence, there was not a trophic cascade where damselfish benefited by the adverse effect of IG predators on hawkfish or coral crabs. These results highlight the manner by which habitat structure can mediate species interactions and emphasize the need to understand the underlying mechanisms.

“…; unpublished data), even if very little bibliographical material is available (Rigaux & Charruau, 2007;Noblet, 2008;Barré, 2009;Legrand, 2009 ;Rigaux & Charruau, 2009;Hervieu, 2011;Pellegry, 2011;Sorrel, 2011;Rigaux, 2013b). Numerous studies on the water vole, carried out with more effective means (genetic) in the Iberian Peninsula also confirm this (Fedriani et al, 2002;Centeno-Cuadros et al, 2011…). Above all, there is a strong similarity on what is known about the water vole (Arvicola terrestris) in England (Stratchan & Moorhouse, 2006…).…”

“…Some exceptions to this have been found on the Iberian Peninsula (Alis et al, 2009;Fedriani et al, 2002;Román, 2003) are not found in France (unpublished data). When the water disappears from a site (artificial drainage of a pond, natural drying-up of part of the waterway), new indicators about the activity of the water vole could perhaps be found on the site for a short period of time.…”

“…This has stimulated works aimed at validating the use of presence signs as indicators of relative abundance of small mammals (Liro 1974;Mankin-Rogalska et al 1986;Giraudoux et al 1995;Fichet-Calvet et al 1999;Van Horne et al 1999). Consequently, the use of presence signs is now widespread among small mammal ecological studies, namely, for our study species (Borgui & Giannoni 1997;Mira & Mathias 1994), for Microtus cabrerae Thomas, 1906(Santos et al 2005Pita et al 2006), Microtus arvalis Pallas, 1778 (Delattre et al 1996(Delattre et al , 1999, Arvicola sapidus Miller, 1908(Fedriani et al 2002, Arvicola terrestris Linnaeus, 1758 (Giraudoux et al 1997;Duhamel et al 2000;Fichet-Calvet et al 2000;Delattre et al 2006), Psammomys obesus Ctretzschmar, 1828 , Talpa europaea Cabrera, 1907 (Delattre et al 2006), Cryptomys zechi Matschie, 1900 (Yeboah & Akyeampong 2001) and other species (Giraudoux et al 1998). We defend the importance and urgency of developing and validating methods, such as using presence signs only, that allow a rapid assessment of species identity in the field, avoiding the logistical constraints of trapping.…”

The Lusitanian and the Mediterranean pine voles (Microtus lusitanicus Gerbe, 1879 and Microtus duodecimcostatus de Selys-Longchamps, 1839) are fossorial sister species and have an allopatric pattern of distribution in Portugal, which includes a potential sympatry area in the centre of the country. The present study aimed to determine the validity of using presence signs in the field for discrimination of the two species in an area of sympatry (Northern Alentejo) and the characteristics that achieve the best classification accuracy. A total of 175 trapping plots were sampled across the study area. Prior to the set up of traps, ten presence signs were randomly selected for measurements of four variables: proportion of soil mounds, mean diameter of mounds, proportion of burrow openings and mean diameter of burrow openings. On the basis of a classification tree analysis, results showed that presence signs can be used to discriminate plots inhabited by one or the other species in the studied sympatry area. The characteristic that most accurately enables species identification is the proportion of burrow openings: for every ten presence signs found in a plot, if more than eight have an opening, then it is inhabited by M. lusitanicus (i.e. mostly burrow openings with few or no mounds present); if eight or fewer have an opening, M. duodecimcostatus is present (i.e. mostly mounds with few or no burrow openings).
