Partitioning of rainfall in a eucalypt forest and pine plantation in southeastern australia: II stemflow and factors affecting stemflow in a dry sclerophyll eucalypt forest and a pinus radiata plantation

In the face of accelerating climate change, conservation strategies will need to consider how marine animals deal with forecast environmental change as well as ongoing threats. We used 10 yr (2009-2018) of data from commercial fisheries and a bather protection program along the coast of New South Wales (NSW), southeastern Australia, to investigate (1) spatial and temporal patterns of occurrence in bull sharks and (2) environmental factors affecting bull shark occurrence along the coast of NSW. Predicted future distribution for this species was modelled for the forecast strengthening East Australian Current. Bull sharks were mostly harvested in small to larger estuaries, with average depth and rainfall responsible for contrasting patterns for each of the fisheries. There was an increase in the occurrence of bull sharks over the last decade, particularly among coastal setline fisheries, associated with seasonal availability of thermal gradients >22°C and both westward and southward coastal currents stronger than 0.15 and 0.60 m s-1, respectively, during the austral summer. Our model predicts a 3 mo increase in the availability of favourable water temperatures along the entire coast of NSW for bull sharks by 2030. This coastline provides a uniquely favourable topography for range expansion in the face of a southerly shift of warmer waters, and habitat is unlikely to be a limiting factor for bull sharks in the future. Such a southerly shift in distribution has implications for the management of bull sharks both in commercial fisheries and for mitigation of shark-human interactions.

Survey Results

Soil-dwelling millipedes were methodically hand-sampled in two second-rotation Pinus radiata stands in Stoodley Plantation in north-central Tasmania. Eleven of 14 species collected were natives, and native millipedes comprised 83% of the 1 456 identified specimens. The average millipede catch in 40 x 0.5 m2 quadrats was 74 individuals/m2. All nine of the native species of Chordeumatida, Polydesmida and Polyzoniida found in the survey had previously been collected in native forest within a 10 km radius of the pine plantation. Historical records indicate that Stoodley Plantation was established on abandoned farmland, and the two sampled areas have carried P. radiata for at least 60 years. The survey results support the suggestion that plantation development on cleared farmland can assist in local-scale conservation of native invertebrates.

Rattus Fuscipes

Before, during and after a clearing operation for pine plantation establishment, small mammals were trapped on ridges which were to be cleared of all vegetation, and in adjacent gullies which were to be permanently retained under native forest. Rattus fuscipes was the most abundant native species on all grids throughout the study, while R. lutreolus, Antechinus stuartii and A. swainsonii were in low abundance. Clearing in early summer, the breeding season in most of these species, resulted in an acceleration and accentuation of population turnover. Some juveniles and subadults may have moved from the ridges during clearing, while breeding adults remained and probably perished. Populations of R. fuscipes on ridge areas were drastically reduced by clearing and windrowing, but subadults recolonized the affected areas within 1-2 months. Results for the other three native species were inconclusive, due to the few individuals captured at any time during the study. The exotic species Mus musculus began to invade immediately following windrow burning.
