Although the distribution and composition of cool temperate rainforest in eastern Australia may be regarded as well documented, the recent discovery of cool temperate rainforest stands dominated by Atherosperma moschatum in the Pilot Wilderness area of Kosciuszko National Park shows that our knowledge is still incomplete. The additional discovery of 10 plant species previously unrecorded for the park including large specimens of Elaeocarpus holopetalus highlights the fact that although the flora and vegetation of the alpine and subalpine tracts of Kosciuszko National Park are relatively well studied, the remainder of the park is by comparison understudied and under sampled. Although not actively protected or managed, these cool temperate rainforest stands appear to have been little affected by the 2003 fires in the Australian Alps, with only 2 stands out of 25 showing any fire incursion. However, whether the direct effects of climate change or the indirect effects of human reaction to climate change poses the greatest threat to the continued existence of these stands is an open question. The aim of this short communication is to: a) examine the distribution and composition of these newly discovered stands of cool temperate rainforest and b) to briefly describe the impact of the 2003 fires on this restricted vegetation type.
Unique features of a global human ectoparasite identified through sequencing of the bed bug genome
(2016)
The bed bug, Cimex lectularius, has re-established itself as a ubiquitous human ectoparasite throughout much of the world during the past two decades. This global resurgence is likely linked to increased international travel and commerce in addition to widespread insecticide resistance. Analyses of the C. lectularius sequenced genome (650 Mb) and 14,220 predicted protein-coding genes provide a comprehensive representation of genes that are linked to traumatic insemination, a reduced chemosensory repertoire of genes related to obligate hematophagy, host–symbiont interactions, and several mechanisms of insecticide resistance. In addition, we document the presence of multiple putative lateral gene transfer events. Genome sequencing and annotation establish a solid foundation for future research on mechanisms of insecticide resistance, human–bed bug and symbiont–bed bug associations, and unique features of bed bug biology that contribute to the unprecedented success of C. lectularius as a human ectoparasite.
