Marine ecosystems are being continually impacted by human activities and, among these, fisheries have been one of the most damaging. Fisheries modify the structure and functioning of food-webs through biomass removal and physical damage to the seabed, leading to loss of biodiversity and ecosystem services provided by the oceans. The ecosystem-based...

Fisheries provide 24% of animal protein consumed and employ over 72 million people worldwide. In recent years the world per capita fish consumption has been increasing from an average of 9.9 kg in the 1960s to 19.2 kg in 2012. In Bangladesh and Ghana around 50-60% of animal protein is supplied by fish (12% in India). Fishery and aquaculture sectors...

Question
Hi All, I need to apply the Min/Max Autocorrealtion Analysis (MAFA) and Dynamic factor Analysis (DFA) to a short, not stationary time series. These methods have been programmed in R (there is a chapter in one of Zuur books) but now it seems that there are not packages to do so (at least for MAFA). Can anyone help me?
Thank you in advance.
Question
Hi,
I am trying to compute the relative importance of predictors of a set of GLS models in R.
I use
importance(model.avg(M_B, rank = AIC, subset = cumsum(weight) <= .95))
but this calculates the importance of predictors only on a part of the models (6 in total while I have 32 competing models)
SP_bcurrents W_SST W_CHLA SP_SSAL
Importance: 1.00 0.99 0.98 0.97
N containing models: 6 4 4 3

Thank you for your help!
Question
Does anyone know how to extract values from a netCDF? I dowloaded temperature data for the whole Mediterranean Sea from MYOCEAN database for a range of depths (1-5000m). I need to extract values of temperature at the lowest depth (bottom temperature) for my sampled stations (these varies between 10-800m depth.
Thank you very much in advance.
Question
Hi All,
Does anyone know what would be a suitable scale to investigate possible changes in fish assemblages in an area of about 35,000 km2? I have 19 years of fishery-independent survey data with my sampling stations on 10km grid, is that too coarse for this type of study? Thank you

Ecosystem based approaches for fishery management are globally recognised as the most efficient way to achieve the goal of sustainable exploitation of living resources and marine ecosystems conservation. Combined with the implementation of marine spatial planning, optimisation of socioeconomic benefits can be achieved still preserving marine biodiversity. This project represents an application of an ecosystem based approach to fisheries management in central Mediterranean Sea including the identification of spatial areas for the conservation of demersal assemblages by applying two interdisciplinary modelling approaches: multivariate statistics and habitat suitability mapping
