scientific advisors (https://ec.europa.eu/ research/sam/index.cfm?pg=hlg) whose effectiveness has yet to be determined. Politics and advocacy can also have a role. The closure by Canada of its CSA office coincided with a strong ideological shift in the national government, although a recently elected government has promised to re-instate the position ( http://pm. gc. ca/eng/minister-science-mandate-letter). The EC decision to rescind the position was preceded, and arguably heavily influenced by, advocacy-based, lobbying efforts [3]. Discontent by vested interests with independent scientific advice is not uncommon, challenges to the listing advice from COSEWIC on polar bear (Ursus maritimus) providing one illustrative example [16].

To fully realize the benefits of societal investments in science, it is self-evident that governments should fully utilize the ultimate product of science (evidence) to strengthen policy and better inform decision-making. Societies invest a great deal to generate peer-reviewed scientific evidence; it can also cost a great deal not to use it wisely and not to communicate it responsibly. It need not, and should not, be wasted.

Concluding Remarks The compelling argument has been made that science advisory systems should comprise three fundamental components: deliberative advice; informal advice; and advice in emergencies [1,11,12]. Deliberative or formal advice can be provided, albeit not coordinated, by a combination of some of the models considered here. Informal advice can also be requested of, and provided by, a subset of advisory models; having chaired an LRAB (J.A.H.) and a national academy (N.C.S.), we can attest to the value that decision-makers place on such advice. However, in addition to other deficiencies (Figure 1, Table 1), none of these models provides for regular and direct communications between those providing the advice and national heads of government and their cabinets. We feel that such a connection is vital. We conclude that a well-supported CSA, with strong links to the advisory capacities of government departments (possibly through their own CSA offices, as in the UK), STACs, national academies, and supranational bodies is optimal for ensuring the integrity of science advice throughout the decision-making system of a government, and for providing informal advice when necessary, especially during emergencies.

them to contemporary conservation issues for a non-technical audience is long overdue. Gillson's contribution has a broad, international target audience, ranging from researchers and senior undergraduate and postgraduate students in a palaeoecology, conservation, and natural resource management, to conservation practitioners, educators, and policymakers. The first chapter sets the context by discussing the shift from a static view of nature to one which recognises the dynamic complexity of ecosystems that has often confounded a ‘fortress conservation’ approach. From establishing the need to consider change along a past–present–future continuum, the book develops key arguments through a series of case study chapters, beginning with an example that Gillson knows well: managing elephant habitat and populations in African parks and reserves. Extinction, rewilding, fire management, climate change, ecosystem services, and cultural landscapes provide the focus for subsequent chapters.

endeavour, but it does provide an excellent resource list on the current state of knowledge in both palaeoecology and conservation ecology. Perhaps inevitably to maintain a strong thematic focus, some sources that are likely to be familiar to the target audience, for example, the Millennium Ecosystem Assessment, are cited repeatedly, while awareness of other topics is assumed, including the complex process of stakeholder engagement.

Gillson's emphasis on narratives brought to mind a suggestion that I have heard repeated at workshops convened to ‘bridge the gap’ between managers, ecologists, and palaeoecologists – the value of storytelling to communicate landscape histories. While this approach has been put to good use in history and archaeology, scientists have often been reluctant to relinquish the rigour of their analyses [3,4]. The power of Gillson's narrative approach is evident by its absence in the concluding chapter, where messages about collaborative learning, multifunctionality, and shared vision seemed someThe main strength of the book is that its what unsatisfying as general principles engaging narratives of long-term change after the preceding detail, which is where clearly and consistently relate palaeoecol- the undoubted strength of the book lies. ogy to contemporary environmental and conservation management challenges.

potential that Gillson describes and applied palaeo data to their strategic plans or management goals; the sections on wetland restoration and fire management provide good illustrations of where this has been achieved. Gillson has clearly opted to emphasise the positive, setting out opportunities and possibilities for a wider audience in response to the formidable challenges facing conservation, rather than encumbering readers with uncertainties and potential obstacles to closer working [7]. Does this imply that my criticism about a lack of critical evaluation should be retracted? Integrating alternative disciplinary views into already complex situations is not straightforward and does require particular attention, as ecologists have learnt [8]. However, to get to that stage, a book like this that raises awareness and sets a strong case for making the effort is very necessary and should be widely welcomed.
