Mycosphaerella ambiphylla sp. nov. (anamorph: Phaeophleospora) and Mycosphaerella aurantia sp. nov., are described from diseased Eucalyptus globulus leaves. In addition, a new fungal record in Australia, M. mexicana, and two new records for Western Australia, M. gregaria and M. parva, are discussed. A key is provided to Mycosphaerella species on E. globulus in Western Australia.

The river tern (Sterna aurantia) is considered to be a globally vulnerable species. It native breeding resident of eastern and central Pakistan, Pan India (except the Trans-Himalayan region), Bangladesh, Myanmar, Thailand Cambodia. non-breeding in Nepal, southern Bhutan, Laos Vietnam with vagrant records from Afghanistan Iran. breeds on sandy islands freshwater lakes rivers, rarely estuaries.

(2)H-(13)C HETCOR MAS NMR is performed on (2)H/(13)C/(15)N-Pro enriched A. aurantia dragline silk. Proline dynamics are extracted from (2)H NMR line shapes and T1 in a site-specific manner to elucidate the backbone and side chain molecular dynamics for the MaSp2 GPGXX β-turn regions for spider dragline silk in the dry and wet, supercontracted states.

online) offers the first evidence that males of one species of spider undergo programmed death immediately following mating and consider the potential adaptive significance of such an unusual behaviour. The two researchers have been studying a species in the cannibalistic genus of orb-weaving spider, Argiope, where there has been some suggestion males may die after mating. But now the researche...
