Grevillea trichantha Olde, a rare species in the Triloba Group is described. It appears to be most closely related to another rare species, G. metamorpha Makinson and is more common, though its localised distribution still requires a high conservation priority. Grevillea trichantha is the third species in the Triloba Group in which the perianth is consistently, but not always uniformly, hairy. A short key differentiating the three species is provided.

Morphological and molecular investigations of taxon relationships among rare species of Tetratheca Sm. occurring near Koolyanobbing, Western Australia, have confirmed the distinctness of T. aphylla F.Muell., T. harperi F.Muell. and T. paynterae Alford and identified three new rare taxa from collections affiliated with T. aphylla and T. paynterae. The recognition of these taxa at specific and sub-specific ranks is based on their different degrees of morphological and molecular divergence, combined with geographic disjunction. Cladistic analysis of nrDNA internal transcribed spacer and cpDNA trnL-trnF sequences from a range of Tetratheca species from Western Australia and the eastern states indicates that T. aphylla, T. harperi and T. paynterae belong to three separate evolutionary lineages and that the endemism displayed among these taxa to small, disjunct ranges within the same geographic area, is a result of in situ speciation due to historical fragmentation. These results exemplify the extremely high conservation value of the Yilgarn banded ironstone ranges. The superficial similarity among the study taxa in having a ‘leafless’ habit can be seen to be adaptive convergence in response to the marginal and semi-arid environments in which they occur, and this character is highly homoplastic within the genus.

Progressive Hypoxia

We measured the metabolic rate of three fishes (Lepidogalaxias salamandroides, Galaxiella nigrostriata, Bostockia porosa) that are endemic to the south-west of Western Australia. The first two species have been reported to aestivate, the third does not aestivate when the ponds dry up in late summer. For normoxic conditions, the metabolic rates of B. porosa and G. nigrostriata in water (0.48 mL g–1 h–1 and 0.44 mL g–1 h–1 respectively), are significantly higher than in air (0.21 mL g–1 h–1 and 0.08 mL g–1 h–1 respectively) but for the more benthic and terrestrially mobile L. salamandroides there was no significant difference between VO2 in water (0.29 mL g–1 h–1 ) and air (0.18 mL g–1 h–1). Progressive hypoxia (12, 5 and 2% O2) decreased the metabolic rate of G. nigrostriata and B. porosa in both water and air but there was a reduction in metabolic rate for L. salamandroides only in water. The metabolic physiology of L. salamandroides in water and air is consistent with the capacity to aestivate in moist soil, but the different metabolic response of G. nigrostriata suggests that it adopts a different strategy to L. salamandroides to survive when the ponds dry up in summer. The metabolism of G. nigrostriata in air and water declines with progressive hypoxia (from 12 to 5 to 2% O2). B. porosa does not appear to be able to cope metabolically when out of water or under hypoxic conditions, and therefore would not be able to aestivate.

The Swan Coastal Plain of south-west Western Australia has been extensively cleared since European settlement, with the fertile Pinjarra Plain land system preferentially cleared for grazing; what remains of the native vegetation is of high conservation value despite being highly fragmented and often degraded. The following six taxa of Synaphea R.Br. (Proteaceae), with conservation status corresponding to IUCN Red List categories Threatened and Data Deficient, are restricted to vegetation remnants in this region: S. stenoloba A.S.George, S. odocoileops A.S.George, S. sp. Pinjarra (R. Davis 6578), S. sp. Fairbridge Farm (D. Papenfus 696), S. sp. Pinjarra Plain (A.S. George 17182) and S. sp. Serpentine (G.R. Brand 103). Taxonomic boundaries among these morphologically similar taxa of Synaphea were investigated using morphometric analyses based on characters of leaves, inflorescences, flowers and fruits. Results allow the circumscription of the four informally named taxa from this complex, which will enable their formal description in a subsequent publication. They also provide support for several morphologically closely related taxa, including the provisional distinction of S. sp. Udumung (A.S. George 17058) from close ally S. decorticans Lindl. Two described species (S. odocoileops and S. stenoloba) and several anomalous specimens could not be adequately resolved in these analyses, and further investigation of their boundaries using molecular markers is required.

Significant Difference

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

: The fabaceae are rooted in rosaceae pods known as "vegetables" by the early botanists. They are the third family of angiosperms which includes 642 genus divided into about 18,000 species. The fabaceae family is known as the most important family of the ecosystem as it is indispensable in medicine, agriculture, industry and livestock. The Adenocarpus genus has about 50 species that are frequently found in tropical regions of Northern Africa, the southern part of West Europe and in the central and southern Italy. They are used in traditional medicine for the treatment of several diseases: such as microbial infections, leprosy, scabies, acne, malaria and other plants species are used in agriculture as insecticidal properties. Mainly Adenocarpus mannii species is well represented in the tropical regions of North Africa. It occurs in Angola, Mozambique, Malawi, Guinea, South Africa, Tanzania, and Burundi. In Cameroon, it is encountered in South West Region and West Region. Previous phytochemical studies led to the isolation of several classes of compounds such as flavonoids, alkaloids and triterpenes. Several studies report the phytochemical studies on genus Adenocarpus and chemotaxonomic markers of species of this genus. Herein, we outline all the botanical, pharmacological and phytochemical aspects of Adenocarpus mannii. A brief introduction about fabaceae and the genus Adenocarpus has also been included.

AbstractMadagascar is a high conservation priority. Rainforests receive most of the focus, but the dry deciduous and spiny forests of south-western Madagascar house many endemics, are under high deforestation pressure, and remain largely unprotected. Charismatic vertebrates, like chameleons, face a secondary threat: harvesting for the commercial pet trade. Six chameleons inhabit the arid southwest near Toliara: Furcifer antimena, F. belalandaensis, F. labordi, F. lateralis, F. oustaleti, and F. verrucosus. We measured population densities of three of those species. Furcifer verrucosus has a large distribution, was dense (97.7 ha–1; 95% CI = 60.2-158.6), and inhabited forests and anthropogenic habitats. Furcifer labordi was much less dense (30.8 ha–1; 13.4-70.9), has a restricted range, and has a unique life history that makes it susceptible to perturbations from deforestation or illegal harvesting. Furcifer antimena was the least dense (17.0 ha–1; 9.3-30.9) and has an even smaller distribution range. We lack density data for F. lateralis, but this species was abundant in anthropogenic habitats. Within their respective ranges, there are currently no protected areas for F. antimena and only few for F. labordi; these two species are far less abundant than the more widely spread F. verrucosus. We recommend that high conservation priority be focused on F. antimena and the southern populations of F. labordi due to their restricted distributions, susceptibility to extirpation, lower population densities, and lack of formal protection. Establishing protected areas in the Ranobe region and north of the Fiherenana River, in the Belalanda region, would help protect important populations of these vulnerable species.

I Here describe a few sites on the south side of the valley of the Strymon, which I noticed while stationed there in 1916–1918. All except No. 5 belong to the third type described by Wace and Thompson and consist of large, low flat-topped mounds covered with Hellenistic sherds. This part of the country was anciently inhabited by the Bisaltai.1. At kilometre 70 on the Salonika-Serres road, about three kilometres south-west of Sakavcha, and two-and-a-half kilometres west of Makesh. Round the edges the remains of ancient walls can be easily traced; in places they are still three feet high and the same thickness with small towers at irregular intervals. Remains of house walls can be found everywhere a few feet down.
