| Eutrophication is one of the most important anthropogenic pressures impacting coastal seas. In Europe, several legislations and management measures have been implemented to halt nutrient overloading in marine ecosystems. This study evaluates the impact of freshwater nutrient control measures on higher trophic levels (HTL) in European marine ecosystems following descriptors and criteria as defined by the Marine Strategy Framework Directive (MSFD). We used a novel pan-European marine modeling ensemble of fourteen HTL models, covering almost all the EU seas, under two nutrient management scenarios. Results from our projections suggest that the proposed nutrient reduction measures may not have a significant impact on the structure and function of European... |

| Philippine reefs are mega-diverse but, to date, few ecosystem models have been developed to understand their dynamics and functioning. This study assessed the status of reefs in 12 municipalities of Leyte Gulf, Philippines. It is an important fishing ground experiencing degradation and impacts of super-typhoons—the strongest one was Haiyan (local name: Yolanda). Empirical and literature data were used to develop Ecopath (trophic) models and Ecosim simulations to evaluate the impacts of reduction and increase in productivity on the Leyte Gulf Reef (LGR) ecosystem. Results showed that the LGR’s ecosystem is in a degraded state—dominated by small-medium herbivores and carnivores, with most productivity immediately returned to detritus. In addition, a... |

| The entrance of poultry products into the trade world requires changes in the configuration of these products, such as programs that ensure their quality and biosafety for the consumers. This article aims at presenting new perception on poultry biosafety programs in broiler breeder farms from an ecological perspective, making these programs more efficient and cost-effective, i.e., more competitive. Using literature review, some convergences were found between ecology concepts and biosafety programs. One of these convergences is understanding the farm as an open ecosystem, integrating through adaptation the natural environment with the exotic environment. This also allows understanding how the production area interacts with the environment as to energy... |

| A framework for web-based collaborative teaching has been created. This framework is implemented as an ecological modeling course (http://iee.umces.edu/AV/Simmod.html), but should be flexible enough to apply to other disciplines. I have developed a series of tools to facilitate interactive communication between students and instructors, and among students taking the course. The course content consists of reading materials that describe the theory of systems analysis and modeling, guidelines on how models can be built, and numerous examples and illustrations. The interactive part includes exercises that can be discussed with and evaluated by the instructor, and provides a means to mimic class discussions. To what extent this approach can replace... |

| Ecological modeling has been used as a tool to estimate potential impacts caused by aquaculture to the surrounding environment. In this work, a mathematical model was applied to estimate the maximum amount of pink shrimp (Farfantepenaeus paulensis) culture units (3,100m2 pen enclosures) that could be installed at two shallow estuarine bays of Patos Lagoon (known as Coreia and Porto do Rei) with no significant effects on either water quality or viability of the culture system. To calibrate the model, information about the culture of Litopenaeus vannamei and F. paulensis as well as field data (influence of netting material, water current speed and nitrogen concentrations) were used. Under a bad scenario (water current velocity of 0.01m s–1 and a mesh... |
