“…This study provides support to previous studies that TLs estimated from Ecopath model and SIA are complementary, for example, significant and close-to-one positive correlation were found between TLs estimated by Ecopath and those derived from SIA in Prince William Sound (R 2 = 0.97 in Kline and Pauly, 1998), in a high latitude fjord ecosystem (R 2 = 0.72 in Nilsen et al, 2008), in a subtropical lagoon (R 2 = 0.82, n = 14 in Milessi et al, 2010), and in Bay of Biscay continental shelf food web (R 2 = 0.72, n = 16 in Lassalle et al, 2014). There was also a clear correlation between the TLs estimated by Ecopath and the ␦ 15 N values in Mediterranean marine food web (R 2 = 0.48, n = 24 in Navarro et al, 2011).…”

“…For example, analysis of 14 species in Laguna de Rocha suggested a 13.5% lower in TLs estimated from Ecopath model (Milessi et al, 2010) while analysis of 16 species in Bay of Biscay suggest a <13% underestimation of TLs (Lassalle et al, 2014). The convention of using detritus and discarded material as TL 1 has probably resulted in lower model TL estimates relative to those calculated from SIA (Nilsen et al, 2008;Navarro et al, 2011).…”

“…Several recent studies have shown good agreement between TLs calculated from ␦ 15 N values and those from food web models (Dame and Christian, 2008) although some studies also show that TLs estimated from Ecopath models are different from ␦ 15 N-based TLs (Polunin and Pinnegar, 2000;Milessi et al, 2010). For example, Nilsen et al (2008) shows that TLs from Ecopath are slightly lower than isotope-based estimates and vice versa.…”

“…Specifically, total system throughput is about 411 t km −2 year −1 , near to a subtropical coastal lagoon in Uruguay (451 t km −2 year −1 in Milessi et al, 2010), but just about one fifth of the southern East China Sea (Li et al, 2010b). In addition, estimated mean transfer efficiency of Xiamen Bay ecosystem is 16.9%, very close to 16.3% of the East China Sea (Cheng et al, 2009), higher than Kuosheng Bay in Northern Taiwan (6.5% in Lin et al, 2004), also higher than Daya Bay (8.9% in Wang et al, 2005) and Beibu Gulf (9.1% in Chen et al, 2011) in South China Sea, indicating that the system has high potential for adaptation and resilience capacity.…”

“…Interactions between freshwater and marine sources generate strong gradients of salinity, light, and nutrient availability (Hauenstein and Ramírez, 1986). Biological diversity is generally high in these environments (Milessi et al, 2010). Located in the southern Gulf of Mexico near Campeche Sound, the Tér-minos Lagoon is one of the largest tropical coastal lagoons worldwide, and its recognized environmental importance and protected status are potentially threatened by petroleumrelated industrial activities inshore and offshore (García-Ríos et al, 2013).…”

Biogeochemical cycling and phyto- and bacterioplankton communities in a large and shallow tropical lagoon (Términos Lagoon, Mexico) under 2009–2010 El Niño Modoki drought conditions

Abstract. The 2009-2010 period was marked by an episode of intense drought known as the El Niño Modoki event. Sampling of the Términos Lagoon (Mexico) was carried out in November 2009 in order to understand the influence of these particular environmental conditions on organic matter fluxes within the lagoon's pelagic ecosystem and, more specifically, on the relationship between phyto-and bacterioplankton communities. The measurements presented here concern biogeochemical parameters (nutrients, dissolved and particulate organic matter [POM], and dissolved polycyclic aromatic hydrocarbons [PAHs]), phytoplankton (biomass and photosynthesis), and bacteria (diversity and abundance, including PAH degradation bacteria and ectoenzymatic activities). During the studied period, the water column of the Términos Lagoon functioned globally as a sink and, more precisely, as a "nitrogen assimilator". This was due to the high production of particulate and dissolved organic matter (DOM), even though exportation of autochthonous matter to the Gulf of Mexico was weak. We found that "bottom-up" control accounted for a large portion of the variability of phytoplankton productivity. Nitrogen and phosphorus stoichiometry mostly accounted for the heterogeneity in phytoplankton and free-living prokaryote distribution in the lagoon. In the eastern part, we found a clear decoupling between areas enriched in dissolved inorganic nitrogen near the Puerto Real coastal inlet and areas enriched in phosphate (PO 4 ) near the Candelaria estuary. Such a decoupling limited the potential for primary production, resulting in an accumulation of dissolved organic carbon and nitrogen (DOC and DON, respectively) near the river mouths. In the western part of the lagoon, maximal phytoplankton development resulted from bacterial activity transforming particulate organic phosphorus (PP) and dissolved organic phosphorus (DOP) to available PO 4 and the coupling between Palizada River inputs of nitrate (NO 3 ) and PP. The Chumpan River contributed only marginally to PO 4 inputs due to its very low contribution to overall river inputs. The highest dissolved total PAH concentrations were measured in the El Carmen Inlet, suggesting that the anthropogenic pollution of the zone is probably related to the oil-platform exploitation activities in the shallow waters of the southern of the Gulf of Mexico. We also found that a complex array of biogeochemical and phytoplanktonic parameters were the driving force behind the geographical distribution of bacterial community structure and activities. Finally, we showed that nutrients brought by the Palizada River supported an abundant bacterial community of PAH

Although quantifying trophic interactions is a critical path to understanding and forecasting ecosystem functioning, fitting trophic models to field data remains challenging. It requires flexible statistical tools to combine different sources of information from the literature and fieldwork samples. We present EcoDiet, a hierarchical Bayesian modeling framework to simultaneously estimate food‐web topology and diet composition of all consumers in the food web, by combining (1) a priori knowledge from the literature on both food‐web topology and diet proportions; (2) stomach content analyses, with frequencies of prey occurrence used as the primary source of data to update the prior knowledge on the topological food‐web structure; (3) and biotracers data through a mixing model (MM). Inferences are derived in a Bayesian probabilistic rationale that provides a formal way to incorporate prior information and quantifies uncertainty around both the topological structure of the food web and the dietary proportions. EcoDiet was implemented as an open‐source R package, providing a user‐friendly interface to execute the model, as well as examples and guidelines to familiarize with its use. We used simulated data to demonstrate the benefits of EcoDiet and how the framework can improve inferences on diet matrix by comparison with classical network MM. We applied EcoDiet to the Celtic Sea ecosystem, and showed how combining multiple data types within an integrated approach provides a more robust and holistic picture of the food‐web topology and diet matrices than the literature or classical MM approach alone. EcoDiet has the potential to become a reference method for building diet matrices as a preliminary step of ecosystem modeling and to improve our understanding of prey–predator interactions.
