This has heightened the need for the development of new antimalarial drugs as well as other control methods. Plant based antimalarial drugs continue to be used in many tropical areas for the treatment and control of malaria and hence the need for scientific investigation into their usefulness as alternatives to conventional treatment. -
Matses Indian Rainforest Habitat Classification and Mammalian Diversity in Amazonian Peru
Journal of Ethnobiology 20(1): 1-36 Summer 2000 MATSES INDIAN RAINFOREST HABITAT CLASSIFICATION AND MAMMALIAN DIVERSITY IN AMAZONIAN PERU DAVID W. FLECK! Department ofEveilltioll, Ecology, alld Organismal Biology Tile Ohio State University Columbus, Ohio 43210-1293 JOHN D. HARDER Oepartmeut ofEvolution, Ecology, and Organismnl Biology Tile Ohio State University Columbus, Ohio 43210-1293 ABSTRACT.- The Matses Indians of northeastern Peru recognize 47 named rainforest habitat types within the G61vez River drainage basin. By combining named vegetative and geomorphological habitat designations, the Matses can distinguish 178 rainforest habitat types. The biological basis of their habitat classification system was evaluated by documenting vegetative ch<lracteristics and mammalian species composition by plot sampling, trapping, and hunting in habitats near the Matses village of Nuevo San Juan. Highly significant (p<:O.OOI) differences in measured vegetation structure parameters were found among 16 sampled Matses-recognized habitat types. Homogeneity of the distribution of palm species (n=20) over the 16 sampled habitat types was rejected. Captures of small mammals in 10 Matses-rc<:ognized habitats revealed a non-random distribution in species of marsupials (n=6) and small rodents (n=13). Mammal sighlings and signs recorded while hunting with the Matses suggest that some species of mammals have a sufficiently strong preference for certain habitat types so as to make hunting more efficient by concentrating search effort for these species in specific habitat types. Differences in vegetation structure, palm species composition, and occurrence of small mammals demonstrate the ecological relevance of Matses-rccognized habitat types. Key words: Amazonia, habitat classification, mammals, Matses, rainforest. RESUMEN.- Los nalivos Matslis del nordeste del Peru reconacen 47 tipos de habitats de bosque lluvioso dentro de la cuenca del rio Galvez. -

Phytochemical screening of both the methanolic and methylene chloride extracts indicated the presence of tannins, saponnins, terpenes, steroids and about eight different limonoids. Exhaustive extraction, chromatography and spectral analyses led to isolation of three compounds. The spectrometric analyses and the resulting data - including IR, NMR(H-H COSY and 1HNMR) and the LC - ESI - MS spectra and their interpretation helped to propose the structures of the three compounds. -

CRL-Rodent Genetics and Genetic Quality Control for Inbred and F1 Hybrid Strains, Part II
CRL-Rodent Genetics and Genetic Quality Control for Inbred and F1 Hybrid Strains, Part II ASK CHARLES RIVER FREQUENTLY ASKED QUESTIONS ON-LINE LITERATURE WHAT'S NEW Previous | Index | Next WINTER 1992 Rodent Genetics and Genetic Quality Control for Inbred and F1 Hybrid Strains, Part II Genetically defined rodent strains with stable, identifiable phenotypes have played a central role in the advances made in biomedical research. Such strains have been developed by selection and inbreeding, as was discussed in the fall 1991 document (Part I of this two-part series). That Bulletin also defined basic genetic terms, introduced the concept of genetic quality control, and reviewed the role of colony management in detection and prevention of subline divergence. This document addresses the important role of genetic monitoring, especially the monitoring of qualitative biochemical and immunological markers. Routine genetic monitoring is necessary to detect genetic contamination, the most important cause of subline divergence. Ideal markers for monitoring display simple Mendelian inheritance. They have a phenotype that is not altered by environmental factors but corresponds to the genotype. Markers should be monitored on chromosomes or linkage groups found throughout the genome. Alleles should be codominant so homozygotes and heterozygotes can be distinguished. Skin Grafting Skin grafting is a classical and still essential technique for characterizing inbred strains. It was developed in the 1950s by Billingham and others to detect histocompatibility differences. As histocompatibility (H) is determined by several hundred H genes found on virtually every chromosome, skin grafting reveals subline divergence due to mutation as well as to genetic contamination. Acceptance of reciprocal skin grafts, or isohistogenicity, indicates that animals are isogeneic. -

ABDEL-RAHMAN 1, CHRISTIAN T. CHIMIMBA, PETER J. TAYLOR, GIANCARLO CONTRAFATTO, JENNIFER M. LAMB 1 Sudan Natural History Museum, Faculty of Science, University of Khartoum P. O. Box 321 Khartoum, Sudan Non-geographic morphometric variation particularly at the level of sexual dimorphism and age variation has been extensively documented in many organisms including rodents, and is useful for establishing whether to analyse sexes separately or together and for selecting adult specimens to consider for subsequent data recording and analysis. However, such studies have largely been based on linear measurement-based traditional morphometric analyses that mainly focus on the partitioning of overall size- rather than shape-related morphological variation. Nevertheless, recent advances in unit-free, landmark/outline-based geometric morphometric analyses offer a new tool to assess shape-related morphological variation. In the present study, we used geometric morphometric analysis to comparatively evaluate non-geographic variation in two geographically disparate murid rodent species, Aethmoys ineptus from South Africa and Arvicanthis niloticus from Sudan , the results of which are also compared with previously published results based on traditional morphometric data. Our results show that while the results of the traditional morphometric analyses of both species were congruent, they were not sensitive enough to detect some signals of non-geographic morphological variation. -

(Chico Mendes) Ao iniciar sua luta mostrando ao mundo uma nova forma de impedir a devastação da floresta, com seus "empates", surgia um novo líder, questionado e combatido por muitos, compreendido por poucos. Passados trinta anos, verifica-se que aqueles empates não foram em vão. Hoje estamos cientes da necessidade de preservarmos mais e melhor, valorizando os Povos da Floresta, verdadeiros guardiões da mata e sua biodiversidade, estes, verdadeiros tesouros passíveis de remuneração e compensação, em busca de um mundo melhor para enfrentar a necessidade de conter o aquecimento global.

(Meliaceae- Cedreloideae). Adansonia, sér. 3, 36 (2): 335-349. http://dx.doi.org/10.5252/a2014n2a13 ABSTRACT Ant-plant interactions mediated by special structures provided by plants such as domatia, extrafloral nectaries (EFNs) and food bodies, are very frequent in tropical ecosystems. To understand why ants are frequently encountered on most species of Carapa Aubl. (Meliaceae), we investigated the presence of ex- tranuptial nectaries (ENNs) in all 27 species of the genus, spanning its entire distributional range in tropical Africa and America. We report for the first time in the genus the occurrence of extrafloral nectaries (at the base of the petiole, along the rachis of the pinnately compound leaf, on bracts) petaline nectaries (on the outer surface of petals), and pericarpial nectaries (on the surface of fruits), and confirm the presence of nectaries on leaflets in Carapa. Petiolar nectaries are the most common, occurring in 85% of the species. Nectaries were mainly active in young developing plant organs. Ants were observed foraging on exu- dates from these nectaries. e secretions from these glands help to explain the KEY WORDS abundance of ants on Carapa trees. -
Biogeography and Ecology in a Pantropical Family, the Meliaceae
Gardens’ Bulletin Singapore 71(Suppl. 2):335-461. 2019 335 doi: 10.26492/gbs71(suppl. 2).2019-22 Biogeography and ecology in a pantropical family, the Meliaceae M. Heads Buffalo Museum of Science, 1020 Humboldt Parkway, Buffalo, NY 14211-1293, USA. [email protected] ABSTRACT. This paper reviews the biogeography and ecology of the family Meliaceae and maps many of the clades. Recently published molecular phylogenies are used as a framework to interpret distributional and ecological data. The sections on distribution concentrate on allopatry, on areas of overlap among clades, and on centres of diversity. The sections on ecology focus on populations of the family that are not in typical, dry-ground, lowland rain forest, for example, in and around mangrove forest, in peat swamp and other kinds of freshwater swamp forest, on limestone, and in open vegetation such as savanna woodland. Information on the altitudinal range of the genera is presented, and brief notes on architecture are also given. The paper considers the relationship between the distribution and ecology of the taxa, and the interpretation of the fossil record of the family, along with its significance for biogeographic studies. Finally, the paper discusses whether the evolution of Meliaceae can be attributed to ‘radiations’ from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion. Keywords. Altitude, limestone, mangrove, rain forest, savanna, swamp forest, tropics, vicariance Introduction The family Meliaceae is well known for its high-quality timbers, especially mahogany (Swietenia Jacq.).
