“…In a steady state, a portion of biomass production is transferred into a higher TL through a trophic flow, and the TTE is defined as biomass in TL (n) divided by that in TL (n À 1), assuming a constant biomass stock per unit energy flow across all TLs. Theoretically, the TTE is divided into three components (Kozlovsky 1968;Odum 1968;Burns 1989;Strayer 1991 Chapin et al 2011): consumer production efficiency PE (consumer production/assimilation), assimilation efficiency AE (assimilation/ingestion), and consumption efficiency CE (ingestion/resource production), expressed as the following equation:…”

Knowledge of the diet source and trophic position of organisms is fundamental in food web science. Since the 1980s, stable isotopes of light elements such as 13 C and 15 N have provided unique information on the food web structure in a variety of ecosystems. More recently, novel isotope tools such as stable isotopes of heavy elements, radioisotopes, and compound-specific isotope analysis, have been examined by researchers. Here I reviewed the use of compound-specific nitrogen isotope analysis of amino acids (CSIA-AA) as a useful dietary tracer in food web ecology. Its three key features-(1) offsetting against isotopic variation; (2) universality of the trophic discrimination factor; and (3) sensitivity to source mixing-were compared with conventional isotope analysis for the bulk tissue of organisms. These three advantages of CSIA-AA will allow future researchers to (1) estimate the integrated trophic position (iTP) of animal communities; (2) infer trophic transfer efficiency (TTE) in food webs; and (3) quantify contributions from different resources to animals, all of which are crucial for understanding the relationship between biodiversity and multitrophic ecosystem functioning. Further development of trophic ecology will be facilitated by both methodological refinement of CSIA-AA and its application to a wider range of organisms, food webs, and ecosystems.

Food webs in the ocean: who eats whom and how much?

Responsible Fisheries in the Marine Ecosystem

Over 100 food webs have been published for marine ecosystems to describe the transfer of food energy from its source in plants, through herbivores, to carnivores and higher order predators. The webs suggest that the lengths of the chains that form food webs are typically short (3-4 links), and that ecosystems with long food chains may be less stable than those with shorter food chains.Stomach contents have been the primary means for determining what marine organisms eat. More recently developed techniques include faecal analysis and fatty acid signatures from blood or fat samples. Consumption has been estimated from the volume of food found in stomachs, from the feeding rates of captive individuals and from bio-energetic modelling. Consumption of marine organisms, expressed as a percentage of an individual's body weight per day, ranges from about 4-15% for zooplankton, to 1-4% for cephalopods, 1-2% for fish, 3-5% for marine mammals and 15-20% for sea birds. Immature age classes consume about twice as much (per unit of body weight) as do mature individuals. Furthermore, consumption is not constant throughout the year, but varies with seasonal periods of growth and reproduction. Most groups of species consume 3-10 times more than they produce, and export or pass up the food web about 70-95% of their production. Marine organisms tend to be larger at successive trophic levels and are limited in the sizes of food they can consume. Humans are one of the few species that can prey upon almost any level of the food chain and any size of prey.Food web analysis and estimates of consumption are essential for understanding which ecosystems can support additional species, and which may be less stable and susceptible to species loss through the synergistic effects of fishing or culling. They are also critical tools for understanding changes in ecosystem dynamics as highlighted by a case study from the eastern Bering Sea.

“…Menge et al (1986) distinguiram o termo guilda de grupos funcionais definindo a guilda como um grupo de espécies que utilizam o mesmo recurso e grupos funcionais como método de forrageamento das espécies. Neste trabalhou adotou-se a terminologia "guilda trófica" para definir o grupo de espécies que exploram o mesmo recurso alimentar (Yodzis 1982, Burns 1989.…”

Abstract:This study aimed to evaluate the spatial and temporal variation of the feeding guilds of fish communities of 10 oxbow lakes of the Cuiabá River in the Pantanal. The lagoons were sampled in three periods of the hydrological cycle (beginning and ending of the dry and flooding season of 2005). The feeding guilds were determined through analysis of stomach contents of the most abundant species in the community. Were analyzed 37 species belonging to eight trophic guilds (insectivore, herbivore, omnivore, zooplanktivore, planktivore, detritivore, benthivore and iliophage), whitch varied spatially and temporally. A change in the composition of trophic guilds between the periods and locations was observed, but the number of guilds did not vary for either of them. Our results suggest that spatial and temporal variation in the composition of the guilds can be related to many factors, such as alterations in the composition of the community where new species can contribute to the different trophic guilds; and the exploration of more abundant resources in certain periods of the year favoring the presence of some guilds only in some periods. Keywords: trophic groups, fishes, hydrological cycle, feeding ecology, community structure. Resumo: O presente trabalho teve como objetivo avaliar a variação espacial e temporal das guildas alimentares das comunidades de peixes em 10 lagoas marginais do Rio Cuiabá no Pantanal. As lagoas foram amostradas em três períodos do ciclo hidrológico (início e final da seca e início da enchente de 2005). As guildas alimentares foram determinadas através da análise do conteúdo estomacal das espécies mais abundantes da comunidade. Foram analisadas 37 espécies pertencentes a oito guildas alimentares (insetívora, herbívora, onívora, zooplanctívora, planctívora, detritívora, bentívora e iliófaga), as quais variaram espacial e temporalmente. Observamos uma mudança na composição das guildas tróficas entre os períodos e locais analisados, porém o número de guildas não variou espaço-temporalmente. Nossos resultados sugerem que as mudanças espaciais e temporais na composição das guildas podem estar relacionadas com diversos fatores, como as alterações na composição da comunidade onde novas espécies podem compor as diferentes guildas; a exploração de recursos mais abundantes em determinadas épocas do ano favorecendo a presença de algumas guildas somente em alguns períodos. Palavras-chave: grupos tróficos, peixes, ciclo hidrológico, ecologia alimentar, estrutura de comunidade.
