The global extinction crisis is intensifying rapidly, driven by habitat loss, overexploitation, climate change, invasive species, and disease. This unprecedented loss of species not only threatens ecological integrity but also undermines ecosystem services vital for human survival. In response, many countries have set ambitious conservation targets...

Accounting for the cost of repairing the degradation of Earth’s biosphere is critical to guide conservation and sustainable development decisions. Yet the costs of repairing nature through the recovery of a continental suite of threatened species across their range have never been calculated. We estimated the cost of in situ recovery of nationally...

Changes in buoyancy of marine mammals can be used to infer environmental changes. In multiple seal species, how "fast" an animal sinks reveals body condition changes through shifts in buoyancy as the ratio between lean and lipid tissue changes. However, quantifying similar at-sea changes in Weddell seals (Leptonychotes weddellii) has remained unexp...

Budgeting for biodiversity conservation requires realistic estimates of threat abatement costs. However, data on threat management costs are often unavailable or unable to be extrapolated across relevant locations and scales. Conservation expenditure largely occurs without a priori cost estimates of management activities and is not recorded in ways...

Due to climate change, megafires are increasingly common and have sudden, extensive impacts on many species over vast areas, leaving decision makers uncertain about how best to prioritize recovery. We devised a decision‐support framework to prioritize conservation actions to improve species outcomes immediately after a megafire. Complementary locat...

In the summer of 2019–2020, southern Australia experienced the largest fires on record, detrimentally impacting the habitat of native species, many of which were already threatened by past and current anthropogenic land use. A large-scale restoration effort to improve degraded species habitat would provide fire-affected species with the chance to r...

1.Budgeting for biodiversity conservation requires realistic estimates of the costs of threat abatement. However, data on the costs of managing threats to biodiversity is often unavailable or unable to be extrapolated across relevant locations and scales due to a lack of transparency and consistency in how it was collated. Conservation expenditure...

Australia is in the midst of an extinction crisis, having already lost 10% of terrestrial mammal fauna since European settlement and with hundreds of other species at high risk of extinction. The decline of the nation's biota is a result of an array of threatening processes; however, a comprehensive taxon-specific understanding of threats and their...

Range expansions can be shaped by sex differences in behaviours and other phenotypic traits affecting dispersal and reproduction. Here, we investigate sex differences in morphology, behaviour and genomic population differentiation along a climate‐mediated range expansion in the common bluetail damselfly (Ischnura elegans) in northern Europe. We sam...

The X-chromosome and sex-specific selection can alter the evolutionary trajectory of species. Assessing these processes in a climate-induced range expansion can help us understand species’ persistence. The blue-tailed damselfly (Ischnura elegans) is expanding poleward across northern Europe in response to climate change. In this study we analysed 1...
