- Description: Despite the great potential of palaeo-environmental information to strengthen natural resource policy, science and practical outcomes naturally occurring archives of palaeo-environmental and ecosystem service information have not been fully recognised or utilised to inform the development of environmental policy. In this paper, we describe how Australian palaeo-environmental science is improving environmental understanding through local studies and regional syntheses that inform us about past conditions, extreme conditions and altered ecosystem states. Australian innovations in ecosystem services research and palaeo-environmental science contribute in five important contexts: discussions about environmental understanding and management objectives, improving access to information, improved knowledge about the dynamics of ecosystem services, increasing understanding of environmental processes and resource availability, and engaging interdisciplinary approaches to manage ecosystem services. Knowledge of the past is an important starting point for setting present and future resource management objectives, anticipating consequences of trade-offs, sharing risk and evaluating and monitoring the ongoing availability of ecosystem services. Palaeo-environmental information helps reframe discussions about desirable futures and collaborative efforts between scientists, planners, managers and communities. However, further steps are needed to translate the ecosystem services concept into ecosystem services policy and tangible management objectives and actions that are useful, feasible and encompass the range of benefits to people from ecosystems. We argue that increased incorporation of palaeo-environmental information into policy and decision-making is needed for evidence-based adaptive management to enhance sustainability of ecosystem functions and reduce long-term risks.

- Description: As part of a modern review of all Australian Collembola families, a key is provided to the nine genera of Brachystomellidae currently known from Australia, their morphology is compared, their distribution within and outside Australia is noted and the high diversity of genera in southern regions emphasised. Three Australian genera are endemic, five are also found in South America, South Africa and/or New Zealand and one has a cosmopolitan distribution. The distribution, ecology and habitat preferences of Australian genera are compared. Two genera, Cassagnella Najt & Massoud and Rapoportella Ellis & Bellinger, are newly diagnosed and additions to the description of C. anomala Womersley are given. Australian Cassagnella species appear restricted to southern, humid regions and C. anomala possesses some characters that indicate it is adapted to living in habitats that are periodically flooded. A new species, Rapoportella edwardi sp. n. is described in the rarer genus from drier eucalypt forests. The effect of agricultural practices on an introduced species of Brachystomella is noted and its indicator value emphasised. Possible threats to the endemic genera and species are noted.

- Description: Understanding how increasing risk of frequent and severe fires affects biodiversity and ecosystem function is important for effective conservation and recovery, but large knowledge gaps exist for many taxa in many parts of the world, especially invertebrates. After Australia's 2019–2020 catastrophic bushfire disaster, estimates of biodiversity loss and government priorities for post-fire conservation activities were focused on vertebrates and plants because of lack of knowledge about invertebrates. Our synthesis of published evidence reveals a fragmented and ambiguous body of literature on invertebrate responses to fire in Australian ecosystems, limiting the capacity of evidence to inform effective conservation policy in response to extreme fire events. Peer-reviewed studies are available for only six of the more than 30 invertebrate phyla and 88% were on arthropods, predominantly ants. Nearly all studies (94%) were conducted in terrestrial habitats, with only four studies measuring impacts in freshwater habitats and no studies of impacts on marine invertebrates. The high variation in study designs and treatment categories, as well as the absence of key methodological details in many older observational studies, means that there is substantial opportunity to improve our approach to collating meaningful estimates of general fire effects. To understand the full ecological effects of catastrophic fire events, and design effective policies that support recovery of ecosystems now and in future, it is critical that we improve understanding of how fire regimes affect invertebrates. We list key priorities for research and policy to support invertebrate conservation and ecosystem recovery in the face of increasing fire risk. © 2021 Royal Entomological Society. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Kate Umbers” is provided in this record**
