good night, the protection of escosistemas almost always associated with the protection of a species sombrella generally is the largest carnivore because it is the kind that requires more area for food.

In the event it is a very small area can be associated with the endemic species with greater ecological value.

Dear Guillermo Auad ,  Fisher index can apply for benthic ecosystems of water body?

Hello,

there is also the question of external impact in a system. If you can minimize exteranl (e.g. human) impact, reselience might improve because of natural processes that lead to a better adapted system.

Of course Guillermo is right when he writes that diverse food possibilities improve resilience. But, what do we with monophage  animals (eg. some butterflys)?

Dear Johannes Kostenzer and Guillermo Auad,  so were there is organism living with diverse feeding habit have greater capacity to resilience?

Dear M. Jima, 

I would  in generally agree in this hypothesis, but you also have to consider the vulnerability of the species/ecosystem besides food provision. There can be external reasons for disturbance/natural changes/anthropogenic changes which lead to unviable circumstances. Imho resiliance also depends on palces where species can evade in case of changes. So if there is by far no similar habitat, even good food conditions are not sufficient. Eg. if a icebear living on a icefloe has sufficient feed but climate makes living there insupportable, resilience might also be capacity of adaption to warmer conditions. Very simlified example, of course.

Dear Guillermo Auad,

Can you tell step wise step for calculating it? i cant understand mathematical equations you have provided in paper.  what kind of samples required? what are the parameters we have to collected? how can i begin? please help

ok 

Although the two papers below do not deal with resilience directly, they do imply threshold values for key indicators of sustainability.  I believe the model could be modified for your interests.

Dear Jima

Though I have not worked on the ecosystem, however focused on social vulnerability and adaptation. i developed some indices based on some selected indicators and then used for comparison. 

I mean developing an index and comparing it may be a solution.

it is difficult to make general statements to issues that are usually very specific and complex. One neds to consider aspects that come from the natural environments and those created by humans. E.g. regarding sea level rise one can enhance resilience by moving to higher ground as well as by constructing sea walls or mangrove forests (in tropical countries) that help in containing flooding and coastal erosion....
