“…Such characteristics provide this fish species an opportunistic life-history strategy effectively adapting to habitats with extreme environmental conditions as observed in MP. Although goby is described as a widespread species, relatively tolerant to fluctuations in environmental conditions [37], the establishment of mummichog in MP suggests that this species is more competitive in this type of habitat [15]. In fact, the majority of the studies observed that mummichog is occupying extreme habitats (empty niches) not previously used by native fish species [24,31,38] as it seems to be the current scenario in Guadiana salt marshes accounting on the low degree of habitat overlap (Pianka's index) between gobies and mummichog.…”

This work updates the characterization of winter fish communities in salt marsh areas of Guadiana estuary (SE-Portugal) and discusses the potential risks of habitat dominance by a nonindigenous species (NIS). To this effect, six field campaigns were carried out during winter season targeting the collection of fish species. Individuals from seven different families (marine and estuarine) were collected although the community was dominated by two estuarine species -the native Pomatoschistus sp. (goby) and the NIS Fundulus heteroclitus (mummichog). Goby controlled the majority of salt marsh habitats, except one specific, marsh pool, where extreme environmental conditions were registered, namely high temperature and salinity. Such conditions may have boosted the intrusion of mummichog in this area. This species is well adapted to a wide range of abiotic factors enabling them to colonize habitats where no predators inhabit. Impacts of mummichog intrusion in the Guadiana salt marsh area are still unpredictable since this is the first recorded in such high density. Nevertheless, in scenarios of increased anthropogenic pressure and, consequently, habitat degradation, there is a potential risk of mummichog spread to other habitats and therefore compete for space and food resources with native species.

“…Berkaitan dengan trofik, beberapa spesies menempati peran fungsional dan memanfaatkan sumber daya yang sama di dalam komunitasnya, kelompok ini diistilahkan sebagai serikat (guild). Elliot et al (2002) mengidentifikasi tujuh kategori kelompok fungsional komunitas ikan di estuari yaitu detritivora, herbivora, omnivora, zooplanktivora, zoobentivora, pisivora, dan oportunis.…”

Abstrak Pengetahuan mengenai ekologi trofik merupakan dasar dalam memahami ekosistem secara keseluruhan yang dapat dijelaskan melalui pola hubungan trofik interspesies ataupun interserikat. Penelitian yang berlangsung dari Abstract Trophic Ecology of the Fish Community in Segara Menyan Coastal Lagoon,Subang, West Java Knowledge of trophic ecology is one way to understanding the whole ecosystem which explained by trophic relationship pattern (interspecies or interguild). The research was examined from January to December 2011. The objective research was described of the trophic ecology, i.e. trophic index and dominant prey, trophic guild and trophic level, and spatio-temporal variation of fish community in

“…Furthermore, in the digestive contents of E. foordi and C. canadensis, all prey have been swallowed head first. This predation mode is also described as a typical predation mode for extant piscivorous fishes (Elliott et al 2002). Piscivores generally reorient their prey after catching it in order to swallow it head first and lying on its side (Reimchen 1991, Nilsson & Brönmark 2000.…”

In past and present ecosystems, trophic interactions determine material and energy transfers among species, regulating population dynamics and community stability. Food web studies in past ecosystems are helpful to assess the persistence of ecosystem structure throughout geological times and to explore the existence of general principles of food web assembly. We determined and compared the trophic structure of two Devonian fish assemblages [(1) the Escuminac assemblage (ca. 380 Ma), Miguasha, eastern Canada and (2) the Lode assemblage (ca. 390 Ma), Straupe, Latvia] with a closer look at the Escuminac assemblage. Both localities are representative of Middle to Late Devonian aquatic vertebrate assemblages in terms of taxonomic richness (ca. 20 species), phylogenetic diversity (all major groups of lower vertebrates) and palaeoenvironment (palaeoestuaries). Fossil food web structures were assessed using different kinds of direct (i.e. digestive contents and bite marks in fossils) and indirect (e.g. ecomorphological measurements, stratigraphic species co-occurrences) indicators. First, the relationships between predator and prey body size established for the Escuminac fishes are comparable to those of recent aquatic ecosystems, highlighting a consistency of aquatic food web structure across geological time. Second, non-metric dimensional scaling on ecomorphological variables and cluster analysis showed a common pattern of functional groups for both fish assemblages; top predators, predators, primary and secondary consumers were identified. We conclude that Devonian communities were organized in multiple trophic levels and that size-based feeding interactions were established early in vertebrate history. • Key words: digestive contents, fossil fish, Devonian, ecomorphology, palaeoecology, bottom-up control, top-down control. Ursulines, Rimouski, Québec, G5L 3A1, Canada; richard_cloutier@uqar.ca The trophic structure of recent ecosystems has long been described as controlled either by lower trophic levels (bottom-up control) or by higher trophic levels (top-down control) depending on species interactions. In extant aquatic ecosystems, both bottom-up and top-down controls are recognized (McQueen et al. 1989, Menge 2000, Arreguín-Sánchez 2011. Large species are represented in the upper trophic level, but in relatively low abundance, whereas smaller and more abundant species represent lower trophic levels (Cohen et al. 1993) implying that relationships between predator and prey total lengths can be estimated.Trophic interactions in taxonomically, environmentally and temporally diverse ecosystems of the past have been reconstructed based on direct (e.g. digestive contents) and indirect (e.g. species co-occurrences) indicators such as for e.g. the Cambrian (Vannier & Chen 2005, Dunne et al. 2008, Vannier 2012, Devonian (Lebedev 1992, Lukševičs 1992, Novitskaya 1992, Mark-Kurik 1995, Habgood et al. 2003 (Maisey 1994, Wang et al. 2005) and the Quaternary (Nenzén et al. 2014). Most of these studies rely on qualitative d...
