A trophic analysis of target species of macrobenthos in a subtropical coast community: a taxa relationship essay

Studies on the feeding habits of aquatic organisms are a requirement for the management and sustainable use of marine ecosystems. The aim of the present research was to analyze the habits and trophic similarities of decapods, starfish and fish in order to propose trophic relationships between taxa, using Hennigian methods of phylogenetic systematics. This new grouping hypothesis, based on shared and exclusive food items and food types, corresponds to the broad taxonomic groups used in the analysis. Our results indicate that algae, Mollusca, Polychaeta, Crustacea, Echinodermata and Actinopterygii are the most exploited common resources among the species studied. Starfish were differentiated from other organisms for being stenophagic, and were grouped for feeding on bivalve mollusks. A larger group of fish and crustaceans shares algae and mainly crustaceans as food items. A third group united all eight species of Actinopterygii. This largest subgroup of fish is typically carnivorous, feeding on Anthozoa and a great quantity of Crustacea. Synodus foetens has a special position among fishes, due to its unique feeding on nematodes. A Euclidean distance dendrogram obtained in a previous publication grouped S. foetens with starfish. That result was based on a few non-exclusive shared similarities in feeding modes, as well as on shared absences of items, which are not an adequate grouping factor. Starfish are stenophagic, eating bivalves almost exclusively. Synodus foetens and Isopisthus parvipinnis have restricted food items, and are thus intermediary in relation to starfish, decapods, and other fish, which are euryphagous. The trophic cladogram displays details of food items, whether or not shared by all species. The resulting trophic analysis is consistent with known historical relationships.

14, de Jean Echenoz, un récit de guerre à l’épreuve du pathos

14 is a recently published novel by a French contemporary writer, Jean Echenoz. Having the First World War as its core subject, the text covers the main traditional themes of war novels. Its interest, however, does not lie in what it says about the war, but rather in how the war is told. In fact, 14 points out the main horrors of the war, without engaging in pathos. In order to do so, Echenoz resorts to two groups of techniques, whose main purpose is to lighten the dramatic effect of the war scenes depicted. Surprisingly, the result is a text which recounts the crude horrors of war.
