\subsection{How should we use different

What for and how we can use networks is perhaps one of the biggest
`gaps' we have in network ecology (Tim's EBV ms), and there is a serious
need to start drawing clear, ecological links between network form and
function (although see Delmas et al., 2019). That being said one of the
most important things we can do is to be aware of the parameter space
that is possible given a specific definition of a network and operate
within those parameters. See table for an overview. Also tie it back to
scale - specifically the idea that the fact that metawebs operate at
evolutionary scales they are not suitable for `dynamic' processes,
although they do have the potential to think about novel species
entering the network/community\ldots{}

\section{The future value of
networks}\label{the-future-value-of-networks}

It should be clear that there is a high degree of interrelatedness and
overlap between the way a network is constructed (modelled or predicted)
and the process(es) it captures, these are encoded (embedded) within the
network and ultimately influences how the network can and should be used
(Berlow et al., 2008; Petchey et al., 2011). It is probably both this
nuance as well as a lack of clear boundaries and guidelines as to the
links between network form and function (although see Delmas et al.,
2019) that has stifled the `productive use' of networks beyond
inventorying the interactions between species. Here we will attempt to
address this by linking some of the different network `types' to some of
the current global challenges in biodiversity.

\begin{quote}
what is the future value of networks?
The Terry \& Lewis (2020) paper looks at some methods but is
specifically looking at a bipartite world\ldots{}
\end{quote}

I think a big take home will (hopefully) be how different approaches do
better in different situations and so you as an end user need to take
this into consideration and pick accordingly. I think Petchey et al.
(2011) might have (and share) some thoughts on this. I feel like I need
to look at Berlow et al. (2008) but maybe not exactly in this context
but vaguely adjacent. This is sort of the crux of the argument presented
in Brimacombe et al. (2024) as well.

Do we expect there to be differences when thinking about unipartite vs
bipartite networks? Is there underlying ecology/theory that would assume
that different mechanisms (and thus models) are relevant in these two
`systems'.
