The Rediscovery and Distribution of Rumex drummondii (Polygonaceae) in South-Western Australia

Rumex drummondii Meisn., a south-western Australian endemic vascular plant species recorded from widely separated localities, had not been collected for 46 years and was considered possibly extinct. The methods developed from search theory, which has been used for finding lost people or objects, were applied to finding R. drummondii, starting from previous records. Eleven populations of the species were discovered within a 50 km radius in the Kalgan River and Manypeaks region. A disjunct population of six plants was found in 1992 in a parking area at a crossing of the Moore River, 480 km north north west of the others, but had disappeared by 1994. Surveys in the Gingin Brook and Moore River region and between Kalannie and Kulja, another disjunct record, failed to find further plants. The species occupies temporarily wet depressions, lake edges and roadside excavations and dam edges protected from grazing by sheep; habitats also occupied by congeneric weedy species. The species occurs on road verges and farmland and is known from one nature reserve. The rediscovery of R. drummondii enables it to be included in the assessment of potential biological control agents for related weed species in the genera Emex and Rumex.

THE desert mouse Pseudomys desertor is a medium sized rodent (15 – 30 g) which has a widespread distribution throughout the arid zone of Australia (Menkhorst and Knight 2001). It is considered locally abundant in habitats containing samphire, sedge, nitrebush or mature spinifex grasslands. A tolerance to disturbed habitat (from mining or grazing) has also been noted (Read et al. 1999). The distribution of the species once extended from the Murray-Darling through the Flinders Ranges to the Gibson and Great Sandy Deserts, to the west coast and onto Bernier Island (Read et al. 1999; Menkhorst and Knight 2001). Since European colonisation there has been a contraction of the species’ range to the central deserts (Kerle 1995; Read et al. 1999). In Western Australia, the most southerly historical or contemporary record, is from the Wanjarri Nature Reserve (near Mount Keith), 370 km north of Kalgoorlie (D. Pearson pers. comm.; Western Australian Museum fauna database: http://203.30.234.168/). Recently, however, a suspected P. desertor was caught north-west of Queen Victoria Springs (QVS) in the Great Victoria Desert (GPS 30o 03’ 56’’S; 122o 55’ 28’’E), approximately 350 km to the south-east of its most southern known locality. The specimen had the distinctive buff-orange eye ring, size and general features of P. desertor described in Kerle (1995) and Menkhorst and Knight (2001). Prior to release of the specimen, an ear biopsy was obtained for DNA investigation and genomic DNA was extracted from the biopsy via a variation on the salting out procedure of Miller et al. (1988).

The aim of the work is to supplement and clarify the annotated list of vascular plants of “Castel” nature reserve on the Southern coast of the Crimea. Methods. The work is based on the results of long standing field research, which was carried out by the traditional route-reconnaissance method, analysis of YALT herbarium materials and data from literary and Internet sources. Arealogical and biomorphological characteristics of species are given according to "Biological Flora of the Crimea" by V.N. Golubev, biotope coding according to EUNIS habitat classification. The nomenclature of taxa corresponds to the " Spontaneuos flora of the Crimean peninsula" by A.V. Yena and to international databases Euro+Med PlantBase, The Plant List, Catalog of Life. Results. An additional annotated list of vascular plants of “Castel” nature reserve has been compiled, including 152 species, subspecies and cultivars from 97 genera of 38 families, of which 53 genera and 11 families have also not been cited for this territory before. Arealogical, biomorphological, biotopic and sozological characteristics of the taxa are given. As a result of a critical analysis of the list previously published by E.S. Krainyuk, four species were redefined, two species were proposed to be excluded from the flora of the specially protected natural area, several taxa are considered doubtful. Conclusions. The list of vascular plant taxa in “Castel” nature reserve has been supplemented with 11 families, 53 genera, and 152 species, subspecies, and cultivars; several species from the previously compiled list have been proposed to be excluded or considered doubtful. Thus, the flora of the protected area includes at least 425 species from 68 families. For the first time, the biotopic characteristic of the flora of the reserve was established.

This paper deals with the description of two new species of Horismenus Walker (Hymenoptera: Eulophidae) from Brazil, parasitoids of larvae of Adetus analis (Haldeman) (Coleoptera: Cerambycidae). Both species are similar to Horismenus steirastomae (Girault), a species that also parasitizes cerambycids. Adetus analis is a pest of Sechium edule (Jacq.) Swartz (Cucurbitaceae), a minor crop in Brazil, Argentina and U.S.A., but also feeds in stems of Pereskia aculeata Miller (Cactaceae), an ornamental plant that has become a problematic weed species in Africa, where it was introduced. The two new Horismenus species are described, diagnosed, and compared to H. steirastomae.

Patterns of plant assemblages in habitats located within agroecosystems are poorly understood. A study of the seedbank and standing vegetation in 10 soybean [Glycine max (L.) Merr.] fields, their adjacent boundaries, and adjoining woody hedgerows was undertaken in Ontario. The objective was to examine the composition of plants of conservation value and weedy species in these habitats. The seedbank of each habitat was determined from soil cores in quadrats located at regular intervals along transects, using the seedling emergence method in the greenhouse. The vegetation was surveyed in plots adjacent to the seedbank sampling areas. There was no significant difference in total species richness of vegetation or the seedbank among habitat types. However, there was a marked difference in species composition. In the seedbank, no difference in weed species richness among habitats was observed. In vegetation, however, fields harboured significantly more weedy species than adjacent boundaries and hedgerows. The dissimilarity between the seedbank and the vegetation was confirmed in detrended correspondence analyses, which showed that hedgerow vegetation, and to a lesser extent boundary vegetation, differed from field vegetation and all the habitats of the seedbank. The analysis of soil properties indicated that organic matter and nutrient levels were often higher in hedgerows than in fields. It can be concluded that hedgerows are valuable habitats for plant diversity and that weed species represent a minor component of their overall vegetation composition.

AbstractThe seasonal abundance and rates of parasitism of three species of Mesoclanis seed flies was studied in South Africa. The three species occur on Chrysanthemoides monilifera, and were recorded during most months of the year, whenever C. monilifera was flowering. At three sites in KwaZulu-Natal, numbers of eggs per capitulum of Mesoclanis polana Munro were highest on C. monilifera rotundata between June and November (winter/spring), towards the end of the main flowering flush. Parasitism of M. polana was between 50% and 90% for most of the year. Two other species of Mesoclanis (M. magnipalpis Bezzi and M. dubia Walker) occurred together on C. m. rotundata in the Eastern Cape (St Francis Bay), where parasitism during the year was between 55% and 95%. Peak numbers of eggs per capitulum (M. magnipalpis and M. dubia combined) occurred in May/June (winter), in the latter part of the main flowering flush. Mesoclanis magnipalpis was the only species recorded on C. m. pisifera in De Hoop Nature Reserve (Western Cape), where there was only one peak of oviposition (May/June), coinciding with the short and discrete flowering period of this subspecies. Parasitism was between 50% and 65%. At least nine species of parasitoid were reared from immature Mesoclanis stages. Eurytoma sp. (Eurytomidae) was a dominant parasitoid at all sites. Results are discussed in relation to the possible effectiveness of species of Mesoclanis seed flies as biological control agents of C. monilifera in Australia.
