Conservation Physiology, a fully open access journal (authors and readers can publish and access the content for free), is published on behalf of the Society for Experimental Biology and it is part of the Oxford University press in the UK.
The purpose of Conservation Physiology is to publish research on all taxa related to how organisms, populations, and ecosystems respond physiologically to environmental changes. Research related to restoration of populations and ecosystems including policy and management is also suitable for this journal.
Even though this journal does not address directly open access, they have a link offering information about open access from the publishing company, Oxford University Press (OUP). The mission of the OUP, on open access, is to facilitate the widest possible dissemination of high quality research, while embracing both green and gold open access.
The OUP has adopted publishing open access journals since 2004, and has accomplished it in different ways. For instance, the journal of Nucleic Acids Research, a former subscription publication, was moved to an open access model in 2005; thereafter in 2013 it achieved its highest impact factor ever. The OUP has also launched new, fully open access journals, such as Conservation Physiology.
The OUP recognizes economical constrains of offering fully open access for all journals. In fact, they identify publication expenses such as article processing charges. Although, they highlight the importance of scholarly societies and associations to cover those charges in fully open access journals. In the near future the OUP expects the publishing industry to be mixed; some areas of research might fit fully open access better, while others might require optional open access (i.e. authors pay extra for this feature).
Conservation Physiology fits the model of the OUP by partnering with the Society for Experimental Biology to cover publishing expenses. My guess is that the professional society obtains funds to cover the journal expenses from both membership and meeting registration fees. In the end, researchers, universities and institutes appear to still be paying, indirectly, to be able to publish. Nevertheless, the benefit to the general community of open access is that everyone is able to attain the information for free.
