Conservation And Management

Lumholtz’s tree-kangaroo (Dendrolagus lumholtzi) is an iconic species in far north Queensland yet little is known about its health or population status. Studies on this species have been conducted in a limited number of locations and focused primarily on ecology, habitat use and home-range size. The species is relatively common in the Atherton Tablelands but habitat loss, predation by domestic, feral and wild dogs, vehicle strike, low fecundity, and disease have been identified as threats to the population. We review knowledge of population ecology and threats for this species, and include a novel collation of disease reports on all tree-kangaroos with particular reference to Lumholtz’s tree-kangaroo. Health of Lumholtz’s tree-kangaroo appears to be impacted by the increase in humans and domestic animals in their range. There have been reports of melioidosis, toxoplasmosis, tick paralysis and blindness in wild tree-kangaroos. We identify where increased information on health and population viability will improve conservation and management of the species.

Riparian habitat disturbed by reservoir management does not function as an ecological trap for the Yellow Warbler (Setophaga petechia)

Setophaga Petechia

Ecological traps arise when anthropogenic change creates habitat that appears suitable but when selected reduces the fitness of an individual. We evaluated whether riparian habitat within the drawdown zone of the Arrow Lakes Reservoir, British Columbia, creates an ecological trap for Yellow Warblers ( Setophaga petechia (L., 1766)) by investigating habitat preferences and the fitness consequences of habitat selection decisions. Preferences were inferred by examining how habitat variables influenced settlement order, and comparing habitat at nest sites and random locations. Males preferred to settle in territories with more riparian shrub and tree cover, higher shrub diversity, and less high canopy cover. Females built nests in taller shrubs surrounded by a greater density of shrub stems. Habitat preferences were positively associated with fitness: nest sites in taller shrubs surrounded by higher shrub-stem densities were more likely to avoid predation and fledge young, whereas territories with more riparian cover, higher shrub diversity, and less high canopy cover had higher annual productivity. We therefore found no evidence that riparian habitat affected by reservoir operations functions as an ecological trap. Current habitat selection decisions may be associated with fitness because Yellow Warblers are adapted to breeding in a heterogeneous environment subject to periodic flooding.
