- Description: The decomposition of animal biomass (carrion) contributes to the recycling of energy and nutrients through ecosystems. Whereas the role of plant decomposition in ecosystems is broadly recognised, the significance of carrion to ecosystem functioning remains poorly understood. Quantitative data on carrion biomass are lacking and there is no clear pathway towards improved knowledge in this area. Here, we present a framework to show how quantities derived from individual carcasses can be scaled up using population metrics, allowing for comparisons among ecosystems and other forms of biomass. Our framework facilitates the generation of new data that is critical to building a quantitative understanding of the contribution of carrion to trophic processes and ecosystem stocks and flows. © 2019 Elsevier Ltd. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Philip Barton” is provided in this record**

- Description: Carrion is a highly ephemeral and nutrient rich resource, characterized by extreme biotic and abiotic stressors. We hypothesized that specific constraints of the carrion ecosystem, and especially its nutrient richness, ephemerality, and competition with microbes, have promoted the evolution of social behaviors in necrophagous insects. We show that group living is prevalent among early succession carrion breeding insects, suggesting that this trait has emerged as an adaptation to facilitate survival in the highly competitive environment of fresh carrion. We then highlight how developmental niche construction allows larvae to compete with microbes, efficiently feed on fresh cadavers, and rapidly reach maturity. We observed that larval societies and parental care are two different strategies responding to similar competitive and environmental constraints. We conclude that intra and interspecific competition on carrion are mitigated by social behavior. © 2021 The Author(s) 2021.

- Description: Research disciplines in science have historically developed in silos but are increasingly multidisciplinary. Here, we assessed how the insect ecology literature published in ecological and entomological journals has developed over the last 20 years and which topics have crossed discipline boundaries. We used structural topic modelling to assess research trends from 34 304 articles published in six ecology journals and six entomology journals between 2000 and 2020. We then identified and compared topics that emerged from the entire body of literature, or corpus, with topics that emerged from a subsection of articles that focused only on insects (insect corpus). We found that, within the entire corpus, topics on ‘Community ecology’, ‘Traits, life history & physiology’ and ‘Ecological methods & theory’ became more prevalent over time (hot topics), whereas ‘Population modelling’, ‘Insect development’, ‘Reproduction & ontogeny’ and ‘Plant growth’ declined in prevalence over the 20 years we surveyed (cold topics). In the insect corpus, we found that hot topics included ‘Thermal tolerance’ and ‘Disease vectors’, whereas cold topics included ‘Herbivore phenology’, ‘Insect-plant interactions’ and ‘Parasitoids and parasites’. ‘Landscape ecology’ was a growth topic area for both corpora. Our findings suggest that insect-related research is a major component of the broader ecological discipline, and there are topics in ecology where insect research aligns with general ecological trends. However, specific topics unique to the insect corpora – such as insect taxonomy – are fundamental to both insect and ecology research. © 2021 Ecological Society of Australia
