Two remarkable new species of the Australian moth genus Gallaba Walker (Lepidoptera: Notodontidae, Notodontinae) from the highlands of Tasmania.

The distinctive notodontine moth genus Gallaba Walker, 1865 is confined to eastern and southern Australia where multiple species inhabit forests, woodlands and heathlands from sea level to montane forests of at least 1650m. The continental island of Tasmania supports four Gallaba species (including these two new endemics) at the current global southern limit of Notodontidae. Two distinctive new species are described from montane and subalpine Tasmania: Gallaba constellata sp.

Shifts in composition of monthly invertebrate assemblages in Moorland differed between lowland and montane locations but not fire-ages.

Understanding seasonal changes in invertebrate populations is important for understanding ecosystem processes and for conservation of invertebrate communities. Few studies have investigated variation in seasonal responses of multiorder and multispecies invertebrate assemblages. To determine whether temporal patterns in invertebrate assemblages and taxa vary between locations and vegetation age since burning, patterns of invertebrate occurrence were investigated monthly for 12 mo in cool temperate buttongrass moorlands at two locations (lowland and montane) containing paired plots with different fire history (young and old regrowth).

Classic metapopulations are rare among common beetle species from a naturally fragmented landscape.

1. The general importance of metacommunity and metapopulation theories is poorly understood because few studies have examined responses of the suite of species that occupy the same fragmented landscape. In this study, we examined the importance of spatial ecological theories using a large-scale, naturally fragmented landscape.
