Horned larks (Eremophila alpestris) had brain cholinesterase activity levels depressed 22% at 3 days posttreatment, and 8% at 16 days. No sick or dead birds found however, no systematic searches were made for the small lark carcasses, nor were specific observations for toxic signs conducted (McEwen etal. 1986)... 

Eremophila sturtii R.Br. and Dodonaea attenuata A.Cunn. in western New South Wales (Table IV). Overgrazing by introduced domestic livestock and the relative absence of fire since European settlement are implicated in the development of this situation which, in several respects, resembles that of the Californian. chaparral communities ( ). Allelopathy is a possible contributing factor. 

Sacculatal (155) and its C-9 epimer, isosacculatal, are two diterpenoid dialdehydes which contribute to the pungent odour of the liverwort, Trichocoleopsis sacculata. Their structures bear a resemblance to the sesquiterpenoid drimanes. A diterpenoid analogue of the cadinene group is found in the structure of dihy-droxyserrulatic acid (156), from Eremophila serrulata (Myoporaceae).

The bicyclic ketone eremophilone 93 (Structure 4.27) was first isolated from wood oil of Eremophila mitchelii. It is also found in many other oils. allo-Er-emophilone 94 is also structurally related.

The isolation and structural elucidation of 12-acetoxy-10,ll-dehydrongaione (19)5 (Stilpnophytum linifolium), freelingnite (20)6 (Eremophila freelingi), and the lactones (21)—(25)7 (Athanasia spp.) have been described. Full details of the...

The only species native to North America is the homed lark (Eremophila alpestris), which breeds in open habitats over much of the continent and south into Central America. This species winters in the southern parts of its breeding range. 

Prezizaene (119) and the related tricyclic sesquiterpenoids (120)—(122) have been isolated from Eremophila georgii. The absolute stereochemistry of these compounds is antipodal to that of the zizaene sesquiterpenoids found in vetiver oil cf. Vol. 3, p. 123 Vol. 4, pp. 94—96) and their biosynthesis probably involves cyclization of 8-acoradiene (115) and rearrangement of the intermediate allocedryl (116) or cedryl (117) carbonium ions or their biological equivalents cf. Scheme 14). ...

Eremophila mitchelli is a rich source of various eremophilane sesquiter-penoids and to those already known can now be added the dienone (285). The chemistry of the eremophilane-related sesquiterpenoid bakkenolide-A (286) has been published. ... 

The absolute configurations of ( + )-calamene (268) and ( + )-7-hydroxy-calamenene (269), metabolites of Eremophila drummondii, have been established by AT-ray crystallographic analysis. These compounds are therefore enantiomeric to calamenenes previously found in other plants. Laevigatin (270), a constituent of the essential oil of Eupatorium laevigatum, has been assigned structure (270) on the basis of spectroscopic evidence and oxidation to-furano-cadalene (271). ... 

The structures of ovatodiolide (101), isolated from Anisomeles indica (Labia-tae), and of its intramolecular cyclization product (102) have been described in full. Macrocyclic diterpenoids have also been obtained from some Eremophila species. The structure (103) was assigned on the basis of an X-ray analysis to an epoxycembradienol obtained from E. george/. A cembrenetriol (104), from...
