We tested the hypothesis that nutrient enrichment affects recruitment of the oyster Saccostrea glomerataand the barnacle Hexaminius popeiana, which are dominant occupiers of space on tree trunks in temperate mangrove forests in New South Wales, Australia. We measured recruitment on artificial settlement plates at high and low intertidal levels under ambient conditions and where we manipulated nutrient levels by adding fertiliser to the water column for 2 mo. To determine whether nutrients influenced temporal patterns of settlement and early mortality of larvae, we quantified recruitment for 2 sampling intervals: on plates that were replaced 4 times at 2 …
Applied Conservation Management Of A Threatened Forest Dependant Frog, Heleioporus Australiacus, Trent D. Penman, F Lemckert, M J Mahony

Threatened species management should be based on reliable scientific research. The giant burrowing frog Heleioporus australiacus is a threatened species in south-eastern Australia, and is often recorded on land managed for commercial forestry. As a result, management prescriptions have been developed in the absence of significant research data. Here, we review the available research data and assess the potential for forest management practices to impact upon this species. The species is restricted to naturally vegetated areas, but avoids steep areas, large rivers and forests with high levels of vegetative ground cover. Individuals spend the majority of the year in the …

Germination Responses Of A Dry Sclerophyll Forest Soil-Stored Seedbank To Fire Related Cues, Trent D. Penman, D Binns, R Allen, R Shiels, S Plummer

Fire is an integral component of many ecosystems worldwide. Many plant species require fire-related cues, primarily heat and smoke, to trigger germination. Despite the importance of this process, the responses of many Australian species to these cues are unknown. Without this knowledge fire management strategies may be developed that are inappropriate for individual species and vegetation communities. In this study we examined the responses of a dry sclerophyll forest seed bank to heat and smoke germination cues. Analysis was possible for 48 taxa within the soil seedbank with 34 of these showing a response to one or both of the …
