Humboldt's woolly monkeys Lagothrix lagotricha have been systematically hunted, mostly for food, to the point of becoming locally extinct wherever humans share their habitat. Remaining populations in the extensive lowland Amazonian range of this species are restricted to remote, unflooded terra firme forests. These populations are, however, quickly wiped out once access is opened by new roads. Terra firme forests, even in entirely undisturbed sites, are seasonally far less productive and can only sustain relatively low population densities. Woolly monkeys are currently more susceptible to hunting than perhaps any other vertebrate in the New World tropics and, as such, should be regarded as highly endangered.

ABSTRACTChemical baits corresponding to natural orchid fragrance chemicals were used to attract and sample male orchid bees in terra firme and flood plain forest sites on the Tambo-pata Reserve in south-eastern Perú. The study was conducted monthly for two years. A total of 38 species of bees was collected at these chemical baits, and although most species were collected from both habitats, 11 species were significantly more common in one habitat than the other. There was considerable variation in the number and types of chemicals to which each of the orchid bee species was attracted.Two cycles of seasonal abundance occurred annually in the number of orchid bee individuals and species collected at the chemical baits. A major peak occurred a month following onset of the wet season, and a minor peak occurred during the dry season. Species body size was related to seasonal activity, but additional factors such as flowering phenology and nest parasites were also probably involved.The number of orchid bee species found on the Tambopata Reserve was similar to the number found in forest sites of eastern and central Brazil, Costa Rica, and Panamá. This homogeneity in species richness is in marked contrast to other insect groups such as Odonata, Lepi-doptera, Asilidae (Diptera), Tabanidae (Diptera), and Cicindelidae (Coleoptera), for which the species numbers recorded on the Tambopata Reserve are the highest for any similar sized area in the world.

The response of two accessions each of black gram (Vigna mungo), adzuki bean (V. angularis) and green gram (V. radiata) to sowing arrangement was evaluated in November, December and January sowings in south-eastern Queensland. Plants were grown in rows 100, 75, 50 and 25 cm apart with a constant within-row density of 20 plants per m, providing population densities of 200, 267, 400 and 800 thousand plants per ha respectively. Dry matter production was generally maximized at the highest population density. However, significant species x sowing arrangement and sowing date x sowing arrangement interaction occurred for seed yield. Yields of black grams were least responsive to population density/sowing date combinations, apparently because of their indeterminate growth habit. The green grams (determinate habit) and adzuki beans (weakly indeterminate) responded to progressively higher population density as sowing was delayed from November to January, reflecting progressively shorter growth duration with later sowing. In each species, yields were generally depressed at the lowest density because vegetative growth was inadequate to achieve complete canopy closure prior to podfilling. Yields were depressed at the highest density for most sowings of the black grams, and the November sowings of the adzuki beans and green grams, because of lodging. It is suggested that sowing date x sowing arrangement interactions might be used to advantage in manipulating sowing date to minimize risk of weather damage in southern Queensland.

Background: The amniotic fluid is fundamental for proper fetal development and growth. Ultrasound visualization of the amniotic fluid permits both subjective and objective estimates of the amniotic fluid. Objective: The objective of this study was to determine the reference values of normal single deepest pocket (SDP) – upper and lower limits, mean SDP and variation of the SDP with gestational age among Igbo women of South-Eastern Nigeria extraction carrying uncomplicated singleton pregnancy. Methodology: This was a prospective cross sectional study involving 400 women carrying uncomplicated singleton pregnancies and who were sure of the date of the first day of their last menstrual period. The single deepest pocket / maximum vertical pool were determined once at presentation at the hospital.. The study was conducted from January 1st to December 31st 2015. The second author carried out all the scanning. The SDP was obtained. Results: The womens’ mean and median ages were the same at 28 years. The gestational age range of the pregnancies was 14-41 weeks. The mean SDP was 5.8cm, while the 5th and 95th percentiles were 3.3cm and 8.5cm respectively. There was no difference in the mean SDP in both term and preterm. There was irregular but continuous rise of mean SDP to a peak of 6.8cm at gestational age of 39 weeks. In conclusion, the participants had a mean SDP of 5.8cm. There was also a positive correlation between SDP and Gestational age. We therefore recommend a longitudinal study to assess perinatal outcome and abnormal amniotic fluid volume among Igbo women of South-Eastern Nigeria. Key words: Single Deepest Pocket, Uncomplicated Singleton Pregnancy, Igbo Women.
