Promoting handwashing with soap behaviour in Kenyan schools : learning from puppetry trials among primary school children in Kenya

While previous research clearly shows that handwashing with soap can prevent many serious illnesses and deaths among children in developing countries, handwashing rates remain low in countries like Kenya. This PhD study explored conditions needed for a successful handwashing with soap initiatives in primary schools in Kenya. It explored the use of puppetry as an approach in communicating hygiene messages as a form of interactive, community-driven method. The research considered a range of conditions that affect such interventions including infrastructure; hardware and software; policy that influence health programs; different actors who have a role to play; and factors affecting sustainability.

Medically-attended respiratory illnesses amongst pregnant women in Brisbane, Australia

There are limited community-based data on the burden of influenza and influenza-like illnesses during pregnancy to inform disease surveillance and control. We aimed to determine the incidence of medically-attended respiratory illnesses (MARI) in pregnant women and the proportion of women who are tested for respiratory pathogens at these visits. We conducted a nested retrospective cohort study of a non-random sample of women aged ≥18 years who had a live birth in maternity units in Brisbane, Queensland, from March 2012 to October 2014. The primary outcomes were self-reported doctor visits for MARI and laboratory investigations for respiratory pathogens. Descriptive analyses were performed. Among 1202 participants, 222 (18.5%, 95%CI 16.3%-20.7%) self-reported MARI during their pregnancy. Of those with an MARI, 20.3% (45/222) self-reported a laboratory test was performed. We were able to confirm with health service providers that 46.7% (21/45) of tests were undertaken, responses from providers were not received for the remainder. Whilst one in five women in this population reported a MARI in pregnancy, only 3.7% (45/1202) reported a clinical specimen had been arranged at the consultation and the ability to validate that self-report was problematic. As the focus on maternal immunisation increases, ascertainment of the aetiological agent causing MARI in this population will be required and efficient and reliable methods for obtaining those data at the community level need to be established.

Using harvest statistics to monitor temporal variation in kangaroo density and harvest rate

Management of the commercial harvest of kangaroos relies on quotas set annually as a proportion of regular estimates of population size. Surveys to generate these estimates are expensive and, in the larger states, logistically difficult; a cheaper alternative is desirable. Rainfall is a disappointingly poor predictor of kangaroo rate of increase in many areas, but harvest statistics (sex ratio, carcass weight, skin size and animals shot per unit time) potentially offer cost-effective indirect monitoring of population abundance (and therefore trend) and status (i.e. under-or overharvest). Furthermore, because harvest data are collected continuously and throughout the harvested areas, they offer the promise of more intensive and more representative coverage of harvest areas than aerial surveys do. To be useful, harvest statistics would need to have a close and known relationship with either population size or harvest rate. We assessed this using longterm (11-22 years) data for three kangaroo species (Macropus rufus, M. giganteus and M. fuliginosus) and common wallaroos (M. robustus) across South Australia, New South Wales and Queensland. Regional variation in kangaroo body size, population composition, shooter efficiency and selectivity required separate analyses in different regions. Two approaches were taken. First, monthly harvest statistics were modelled as a function of a number of explanatory variables, including kangaroo density, harvest rate and rainfall. Second, density and harvest rate were modelled as a function of harvest statistics. Both approaches incorporated a correlated error structure. Many but not all regions had relationships with sufficient precision to be useful for indirect monitoring. However, there was no single relationship that could be applied across an entire state or across species. Combined with rainfall-driven population models and applied at a regional level, these relationships could be used to reduce the frequency of aerial surveys without compromising decisions about harvest management.

Reassessing spatial and temporal dynamics of kangaroo populations

Long-running datasets from aerial surveys of kangaroos (Macropus giganteus, Macropus [uliginosus, Macropus robustus and Macropus rufus) across Queensland, New South Wales and South Australia have been analysed, seeking better predictors of rates of increase which would allow aerial surveys to be undertaken less frequently than annually. Early models of changes in kangaroo numbers in response to rainfall had shown great promise, but much variability. We used normalised difference vegetation index (NDVI) instead, reasoning that changes in pasture condition would provide a better predictor than rainfall. However, except at a fine scale, NDVI proved no better; although two linked periods of rainfall proved useful predictors of rates of increase, this was only in some areas for some species. The good correlations reported in earlier studies were a consequence of data dominated by large droughtinduced adult mortality, whereas over a longer time frame and where changes between years are less dramatic, juvenile survival has the strongest influence on dynamics. Further, harvesting, density dependence and competition with domestic stock are additional and important influences and it is now clear that kangaroo movement has a greater influence on population dynamics than had been assumed. Accordingly, previous conclusions about kangaroo populations as simple systems driven by rainfall need to be reassessed. Examination of this large dataset has permitted descriptions of shifts in distribution of three species across eastern Australia, changes in dispersion in response to rainfall, and an evaluation of using harvest statistics as an index of density and harvest rate. These results have been combined into a risk assessment and decision theory framework to identify optimal monitoring strategies.

Shedding Light on the Microbial Community of the Macropod Foregut Using 454-Amplicon Pyrosequencing

Twenty macropods from five locations in Queensland, Australia, grazing on a variety of native pastures were surveyed and the bacterial community of the foregut was examined using 454-amplicon pyrosequencing. Specifically, the V3/V4 region of 16S rRNA gene was examined. A total of 5040 OTUs were identified in the data set (post filtering). Thirty-two OTUs were identified as 'shared' OTUS (i.e. present in all samples) belonging to either Firmicutes or Bacteroidetes (Clostridiales/Bacteroidales). These phyla predominated the general microbial community in all macropods. Genera represented within the shared OTUs included: unclassified Ruminococcaceae, unclassified Lachnospiraceae, unclassified Clostridiales, Peptococcus sp. Coprococcus spp., Streptococcus spp., Blautia sp., Ruminoccocus sp., Eubacterium sp., Dorea sp., Oscillospira sp. and Butyrivibrio sp. The composition of the bacterial community of the foregut samples of each the host species (Macropus rufus, Macropus giganteus and Macropus robustus) was significantly different allowing differentiation between the host species based on alpha and beta diversity measures. Specifically, eleven dominant OTUs that separated the three host species were identified and classified as: unclassified Ruminococcaceae, unclassified Bacteroidales, Prevotella spp. and a Syntrophococcus sucromutans. Putative reductive acetogens and fibrolytic bacteria were also identified in samples. Future work will investigate the presence and role of fibrolytics and acetogens in these ecosystems. Ideally, the isolation and characterization of these organisms will be used for enhanced feed efficiency in cattle, methane mitigation and potentially for other industries such as the biofuel industry.

Life history aspects of 19 rockfish species (Scorpaenidae: Sebastes) from the Southern California Bight

The authors investigated various life history aspects of 19 rockfish species (Sebastes chlorostictus, S. constellatus, S. dalli, S. elongatus, S. ensifer, S. entomelas, S. flavidus, S. goodei, S. hopkinsi, S. levis, S. melanostomus, S. miniatus, S. ovalis, S. paucispinis, S. rosaceus, S. rosenblatti, S. rufus, s. saxicola, S. semicinctus) from the southern California Bight. These aspects included depth distribution, age-length relationships (of 7 species), length-weight relationships, size at first maturity, spawning season, and fecundity. Growth rates of female S. elongatus, S. hopkinsi, S. ova/is, S. saxicola, and S. semicinctus were higher than male conspecifics. Multiple spawning per season was found in 12 species. Generally, most species spawned between late winter and early summer, though there was some spawning within the genus throughout the year. Spawning season duration ranged from 2 (S. flavidus) to 10 months (S. paucispinis). Spawning seasons tended to start earlier in the year and be of longer duration in the southern California Bight, compared to published data on central California conspecifics. Males matured at a smaller length in 7 of the 17 species studied. Maximum fecundities ranged from 18,000 (S. dalll) to about 2,680,000 (S. levis). (PDF file contains 44 pages.)

Assembleia de aves consumidoras de frutos de sub-bosque em diferentes altitudes em uma área de Mata Atlântica no estado do Rio de Janeiro

Neste estudo, investigamos a distribuição altitudinal da composição, riqueza, abundância das espécies de aves consumidoras de frutos em cinco altitudes e avaliamosa influência da estrutura da vegetação nas diversidades de aves. O estudo foi realizado na Reserva Ecológica de Guapiaçu (REGUA) contígua ao Parque Estadual dos Três Picos (PEPT), no município de Cachoeiras de Macacu, RJ. Coletamos os dados das aves em 24 excursões a campo, incluindo seis bimensais (jul./2010 a maio/2011) e 18 mensais (jul./2011 a dez./2012). Para amostragem das aves, utilizamos o método de captura-marcação-recaptura com redes de neblina, expostas durante sete h/dia em cinco altitudesao longo de uma variação altitudinal de 1000 m. O esforço amostral foi de 8400 h-rede. Para amostragem da estrutura da vegetação, sorteamos três parcelas de 100 m2 adjacentes às linhas das redes em cada altitude, nas quais foram analisadas as densidades de diferentes hábitos de vida. Das árvores, arvoretas e arbustos coletamos as medidas de altura total e diâmetro da altura (no caso dos arbustos, o diâmetro foi coletado a 50 cm do solo). Capturamos 448 indivíduos correspondentes a 35 espécies de aves, distribuídas em 16 famílias. Destas, 26% são endêmicas de Mata Atlântica, incluindo quatro espécies categorizadas com algum grau de vulnerabilidade. Dezesseis espécies foram classificadas como frugívoras enquanto 19 como insetívoras-frugívoras. Leptopogon amaurocephalus, Mionectes rufiventris, Lanio melanops, Chiroxiphia caudata foram capturadas nas cinco altitudes, sendo as últimas duas espécies as mais abundantes. Registramos maior riqueza e abundância de aves nas altitudes de 370 e 770 m. A composição de aves diferiu entre as altitudes, sendo 170 e 1000 m as mais dissimilares. As espécies de aves insetívoras-frugívoras predominaram nos sub-bosques das cinco altitudes. Registramos deslocamento altitudinal de cinco espécies de aves, sendo o maior deslocamento realizado por um indivíduo de Attilarufus, capturado a 770 m e, recapturado a 370 m. Encontramos maior densidade de plantas no sub-bosque nas altitudes 170, 370 e 1000 m. Bambus foram registrados apenas a 1000 m, enquanto que as ervas foram limitadas às altitudes de 170 e 370 m. A estrutura da vegetação apresentou baixa similaridade entre as altitudes, principalmente devido a diferentes densidades das formas de vida e altura das plantas. Três altitudes, 170, 370 e 1000 m, apresentaram alta densidade de indivíduos no sub-bosque, sendo que esta última evidenciou uma estrutura da vegetação relativamente mais simples devido ao alto número de árvores de baixa altura, ao maior número de arvoretas e à presença de bambus. A diversidade de aves foi sensível à estrutura da vegetação, em especial à altura das árvores que apresentou um decréscimo da altura com o aumento da altitude. Esta relação entre a diversidade de aves e a estruturada da vegetação destaca a importância da preservação da estrutura da vegetação para a manutenção da diversidade de aves consumidoras de frutos da REGUA e do PETP
