Palaeoendemic invertebrates weakly reflect palaeoendemic plants across a 52-year-old fire boundary
If palaeoendemic invertebrates depend on palaeoendemic plants, and the latter are threatened by an increase in fire incidence, there is a possibility of an extinction cascade. We test whether there is co-occurrence of palaeoendemic plants and invertebrates in the proximity of a 52-year-old fire boundary in subalpine Tasmania, Australia. We used 2 × 2 m quadrats to record the incidence and cover of vascular plants and trapped invertebrates at each of these 33 sites in six time periods using an alpine Malaise trap and a CD sticky trap. The number of co-occurrences of palaeoendemic plant taxa with palaeoendemic invertebrate taxa was greater than expected by chance (p = 0.020), but many palaeoendemic invertebrates co-occurred with non-palaeoendemic plants. Some of the palaeoendemic invertebrate taxa that were associated with palaeoendemic plants were monophagous, while others were associated with environmental conditions created by a long absence of fire. Many may be threatened if increasing fire incidence destroys vegetation dominated by palaeoendemic plants.
期刊介绍:
Austral Ecology is the premier journal for basic and applied ecology in the Southern Hemisphere. As the official Journal of The Ecological Society of Australia (ESA), Austral Ecology addresses the commonality between ecosystems in Australia and many parts of southern Africa, South America, New Zealand and Oceania. For example many species in the unique biotas of these regions share common Gondwana ancestors. ESA''s aim is to publish innovative research to encourage the sharing of information and experiences that enrich the understanding of the ecology of the Southern Hemisphere.
Austral Ecology involves an editorial board with representatives from Australia, South Africa, New Zealand, Brazil and Argentina. These representatives provide expert opinions, access to qualified reviewers and act as a focus for attracting a wide range of contributions from countries across the region.
Austral Ecology publishes original papers describing experimental, observational or theoretical studies on terrestrial, marine or freshwater systems, which are considered without taxonomic bias. Special thematic issues are published regularly, including symposia on the ecology of estuaries and soft sediment habitats, freshwater systems and coral reef fish.
