Using the example of Madagascar Fauna and Flora Group (MFG), we look at the factors which contribute to the successful maintenance of an international consortium dedicated to the conservation of Malagasy biodiversity. We discuss the philosophy, mission and set-up of the MFG and how, over its 25-year history, it has enabled the productive collaboration of its diverse international members to achieve the common goal of helping to protect Madagascar's unique biodiversity. We explore the benefits of pooling resources to fund a stable base of personnel and infrastructure to maximise the conservation impact of contributions from organisations that might not otherwise be able to fund viable independent programmes and consider the benefits that accrue to partners in the consortium. We highlight specific examples of plant conservation projects set up as a result of the productive working relationship between MFG and Missouri Botanical Garden to reinforce the argument that like-minded organisations working in successful partnership can far exceed the conservation capacity of individual institutions. 相似文献

A new genus Paraconvexitermes is described, comprising Paraconvexitermes acangapua, new species, P. nigricornis (Holmgren) and P. junceus (Emerson), both previously in Convexitermes Holmgren. Now, Convexitermes comprises C. manni Emerson and C. convexifrons (Holmgren). The worker’s digestive tube of both genera along with those of Atlantitermes species allowed to get a better definition of these three genera. Illustrations on the digestive tube and mandibles of workers, soldier’s head, alate’s head and secondary reproductive female of the new genus and species are provided. The phylogenetic relationships with the other nasute genera are discussed along with the “soil feeding” concept. 相似文献

The article discusses daily religious practice among Seventh-day Adventists in Madagascar in- and outside the formal context of church services. Two points, which make a contribution to the ongoing discussions concerned with the nature of religious belief, are stressed. The first is that Adventist practice is of a distinctly intellectual nature, in particular through its use of a Socratic type of Bible study. The second, related to the first, is that church members view religious knowledge as, above all, providing clarity about empirical truth concerning the universe. This implies the lack of a distinction between the world one knows through one's senses and another, transcendental world one believes in. Given that framework, knowledge is more meaningful than faith. 相似文献

The effects of pressure on the enzyme activities of Lacto-bacillus helveticus LHE-511 were examined. Treatment at 400 MPa at 30°C for 10 min completely inhibited acid-producing activity, but the activities of aminopeptidase (AP) and X-prolyl dipeptidyl aminopeptidase (X-PDAP), which are important for acceleration of cheese ripening, increased. These results showed that pressure treatment of L. helveticus LHE-511 selectively inactivates its acid-producing activity. 相似文献

Microcebus ravelobensis is an endangered nocturnal primate endemic to northwestern Madagascar. This part of the island is subject to extensive human
intervention leading to massive habitat destruction and fragmentation. We investigated the degree of genetic differentiation
among remaining populations using mitochondrial control region sequences (479–482 bases). Nine populations were sampled from
the hypothesized geographic range. The region is composed of three inter-river systems (IRSs). Samples were collected in three
areas of continuous forests (CFs) and six isolated forest fragments (IFFs) of different sizes. We identified 27 haplotypes
in 114 animals, with CFs and IFFs harbouring 5–6 and 1–3 haplotypes, respectively. All IFFs were significantly differentiated
from each other with high ΦST values and sets of unique haplotypes. The rivers constitute significant dispersal barriers with over 82% of the molecular
variation being attributed to the divergence among the IRSs. The data suggest a deep and so far unknown split within the rufous
mouse lemurs of northwestern Madagascar. The limited data base and the lack of ecological and morphological data do not allow
definite taxonomic classification at this stage. However, the results clearly indicate that M.
ravelobensis consists of three evolutionary significant units, possibly cryptic species, which warrant urgent and separate conservation
efforts. 相似文献

Hypocotyl explants of Catharanthus roseus produced hairy roots when cultured on Murashige and Skoog (MS) basal medium after infection by Agrobacterium rhizogenes. Explants gave rise to adventitious shoots at a frequency of up to 80% when cultured on MS medium supplemented with 31.1 M 6-benzyladenine and 5.4 M -naphthaleneacetic acid. There was a significant difference in the frequency of adventitious shoot formation for each hairy-root line derived from a different cultivar. Plants derived from hairy roots exhibited prolific rooting and had shortened internodes. Approximately half of the plants had wrinkled leaves and an abundant root mass with extensive lateral branching, but otherwise appeared morphologically normal. Plants with hairy roots that were derived from the cultivar Cooler Apricot developed flowers with petals that were white in the proximal region, whereas the wild-type flower petals are red. PCR and Southern blot analyses revealed that plants derived from hairy roots retained the Ri TL-DNA.Abbreviations BA 6-Benzyladenine - MS Murashige and Skoog medium - NAA -Naphthaleneacetic acid - SH Schenk and Hildebrandt mediumCommunicated by I.S.

An investigation of the seeds of the Madagascan Meliaceae Quivisia papinae has yielded quivisianthone, a novel evodulone group limonoid, together with the known azadiradione and two novel derivatives: 6 alpha-hydroxyazadiradione and 7-deacetyl-7-angeloyl-6 alpha-hydroxyazadiradione. Quivisianthone is the first reported evodulone group limonoid possessing both a ring A lactone and an azadiradione-type ring D. 相似文献
